    Web-based and mailed questionnaires: A comparison of response rates and compliance2005Inngår i: Epidemiology, ISSN 1044-3983, E-ISSN 1531-5487, Vol. 16, nr 4, s. 577-579Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: We assessed response rates and compliance for a printed questionnaire and a Web questionnaire in a Swedish population-based study and explored the influence of adding personalized feedback to the Web questionnaire. Methods: We assigned 875 subjects to I of 3 groups: printed questionnaire, plain Web questionnaire, or Web questionnaire with personalized feedback. The questionnaire had 2 parts, first a general section and then a dietary section. Results: The response rate for the general section was 64% for the printed questionnaire, compared with 50% for the Web questionnaire with feedback. For the dietary questionnaire, the rates were reversed, resulting in a total response rate for the dietary questionnaire that did not differ between printed and web questionnaire with feedback. Conclusions: Interactivity in the Web questionnaire increased compliance in completion of the second section of the questionnaire. Web questionnaires can be useful for research purposes in settings in which Internet access is high.

    A longitudinal study of attitude changes in a medical service organisation after an email introduction2002Inngår i: Interacting with computers, ISSN 0953-5438, E-ISSN 1873-7951, Vol. 14, nr 5, s. 503-519Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A health care organisation was observed over a period of four years during their introduction of email to 6000 employees. The observed managers were positive to email from the start, despite problem with attachments and concerns for lacking computer knowledge. Email had a positive effect on employees attitudes to perceived computer knowledge as well as their abilities to learn more about computers. Negative for all was the blind mass mailings from within the organisation.

    Abstract [sv]

    E-posten är en välsignelse: det blir så mycket lättare att nå folk. Men den är också en förbannelse: vi drunknar i brevflödet. Olle Bälter, forskare vid Tekniska högskolan och Karolinska institutet i Stockholm, lade för två år sedan fram en avhandling om hur e-posten används på svenska arbetsplatser. Här presenterar han sina resultat och ger råd till den som vill ta herraväldet över sin e-post.

    Diagnostic Web-based Monitoring in CS12009Inngår i: Proceedings of the 9th Koli Calling International Conference on Computing Education Research, 2009, s. 63-66Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Students that fall behind during a course are a concern in any teaching situation. Falling behind has negative effects both for students, teachers and the university. Close monitoring of the learning and development can be effective, but is in general timeconsuming and expensive. The use of a web-based diagnostic system that can generate a large (infinite) number of questions could make monitoring both time and cost effective.

    Effektivare e-post: konkreta råd för ett bättre e-postliv2012 (oppl. 1)Bok (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    Trots nya medier och medföljande spådomar om e-postens snara död räknar man med en årlig tillväxt i antalet brev på 6% 2012–2016. Det betyder att du om fyra år förväntas hantera ytterligare 25% mer e-brev än idag. Vi kan inte påverka hur andra använder e-post, men vi kan förändra vårt eget sätt att läsa, skriva och skicka brev vilket kan underlätta situationen avsevärt.

    Electronic mail in a working context1998Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Electronic mail, email, is one of the most widespread computer applications today.While email in general is very popular among its users, there are also drawbacks withemail usage: an increasing amount of messages that overwhelm users, systems that aretoo complex for naive users and at the same time do not support the needs of experiencedusers.In order to answer the main research question “Which design solutions couldimprove the situation of individual email users in a working context when it comes tocommunication and handling large numbers of incoming and stored email messages?”three studies conducted in email users’ working environment are described. The studiedorganisations are one academic research laboratory, one technical company, andone primary medical service organisation. The studies are focused on email usage,organisation of email messages, novice versus experienced users’ needs, managers’email usage, and information and communication overflow.The results indicate that the different strategies used to handle email are a matter ofa balance between advantages and disadvantages of these strategies. The choicebetween them is depending on the users’ total work situation and cannot be understoodby investigating the email communication alone.One advantage of email is the cognitive comfort it brings to its users by liberatingthem from thinking about tasks that can be solved by sending an email message, butthis advantage disappears when the sender cannot trust that the receiver will act uponthe message.Users develop their handling of email with experience and work position. Themedia that managers use to handle the increased communication that follows with ahigher position are email and meetings. One habit that do not change with position isto allow incoming messages to interrupt other work tasks, despite the asynchronousnature of email. This is particularly remarkable for managers who often complain thatthey need more uninterrupted time. The interruptions may partly be attributed to thelack of functionality in email systems to adapt the interfaces to the users’ work habits.In this case incoming messages result in a signal regardless the importance of them.Email is a part of an information and communication flow. Some users have problemshandling this flow. Overflow problems could be diminished by making senders ofmessages more aware of the receivers’ communicative situation. Email systems couldprovide feedback to senders of messages based on the receivers’ perception of his/hersituation.One of the studies indicates that it may be even more complicated to replace an oldemail system than introducing an email system for the first time in an organisation.The investment experienced users have made in the old system may be substantial.A model of time usage for organisation of email messages is also presented in orderto compare different strategies.Several design solutions are suggested with respect to folder usage, sorting emailmessages into folders, reducing the number of stored messages, and tailoring the emailsystem to the user’s work habits.

    How to replace an old email system with a new2000Inngår i: Interacting with computers, ISSN 0953-5438, E-ISSN 1873-7951, Vol. 12, nr 6, s. 601-614Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    All organizations that use email face changes in their email systems. While some of these are only a change of version that has little effect on the organization, many will replace old email systems with new ones, and this may have severe consequences. A case study is presented where the replacement of two old mainframe-based email systems with Lotus Notes failed. Based on this failure, seven important requirements are defined to reduce problems organizations face when replacing old email systems with new ones. These requirements are supported with results from other research.

    Ideas for Engineering Education Inspired by Liberal Arts Colleges: Part 0ne2009Inngår i: Proceedings of  2:a Utvecklingskonferensen för Sveriges ingenjörsutbildningar, Lund December 2-3., 2009, s. 123-124Konferansepaper (Fagfellevurdert)
    Abstract [en]

    After spending the fall 2008 at one of the best colleges in the United States, Williams College, I have stolen several ideas that could be used to improve Swedish engineering education. The first four of these ideas regard admission, study results monitoring, examination demands and sabbaticals. I hope that the remaining ideas can be presented at this conference next year.

    Keystroke level analysis of email message organization2000Inngår i: CHI 2000 - Conference on Human Factors in Computing Systems 'The Future is Here', New York: ACM , 2000, s. 105-112Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Organization of email messages takes an increasing amount of time for many email users. Research has demonstrated that users develop very different strategies to handle this organization. In this paper, the relationship between the different organization strategies and the time necessary to use a certain strategy is illustrated by a mathematical model based on keystroke-level analysis. The model estimates time usage for archiving and retrieving email messages for individual users. Besides explaining why users develop different strategies to organize email messages, the model can also be used to advise users individually when to start using folders, clean messages, learn the search functionality, and using filters to store messages. Similar models could assist evaluation of different interface designs where the number of items increase with time.

    Abstract [sv]

    En vanlig uppfattning är att utbildningskvaliteten vid liberal arts college i USA är mycket svår att överträffa. Många av studenterna lyckas bra i arbetslivet, och fler studenter än vid andra typer av lärosäten går vidare till forskarstudier. Vad är det som skapar denna framgång? Liberal arts education är en utbildningsmodell med rötter i antikt och medeltida bildningstänkande. Den har sitt starkaste fäste vid amerikanska liberal arts college där grundutbildningen är ämnesbaserad och inte yrkesinriktad. Boken ger en fyllig bild av den idémässiga bakgrunden och av centrala pedagogiska metoder, attityder och tänkesätt. Det handlar om det goda lärandet.Boken vänder sig till lärare vid högskolor och universitet, till andra som arbetar inom det högre utbildningssystemet och till alla som har ett allmänt intresse för bildningsfrågor och den pedagogiska praktiken vid högskolor och universitet.

    Enjoying python, processing, and java in CS12010Inngår i: ACM Inroads, ISSN 2153-2184, Vol. 1, nr 4, s. 28-32Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Here we describe an introductory course in computer science where we combined Python, Processing, and core Java. The main reason for this structure was to make the initial contact with programming as gentle, enjoyable, and understandable as possible, while still having the power of graphics and suffi cient Java knowledge for more advanced courses in computer science. This course was designed with a few informal pedagogical principles that facilitated the students' abilities to learn how to learn on their own. Informal results suggest that students may be interested in a greater diversity of programming assignments.

    Demands on web survey tools for epidemiological research2005Inngår i: European Journal of Epidemiology, ISSN 0393-2990, E-ISSN 1573-7284, Vol. 20, nr 2, s. 137-139Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In countries where the Internet access is high, a web-based questionnaire could save time and money compared to printed questionnaires, mainly by eliminating the two steps of transferring answers from printed to a digital data set and manually completing missing and impossible answers. However, many of the features wanted for conducting large epidemiological studies are not available in many web survey systems. Here we describe design issues the investigator needs to be aware of when using web-based questionnaires in epidemiological research.

    Lärstrategier på längden och tvären2015Inngår i: 5:e Utvecklingskonferensen för Sveriges ingenjörsutbildningar, Uppsala universitet, Uppsala universitet, 2015Konferansepaper (Fagfellevurdert)
    Abstract [sv]

    Studiestrategier påverkar vad studenter får ut av sin utbildning. Vi har genomfört enkätstudier (ASSIST och RSPQ) för att mäta strategierna hos civilingenjörsstudenter på två olika program (Datateknik respektive Medicinsk teknik) på KTH. Resultaten visar att för denna tämligen homogena studentgrupp finns det inga större skillnader mellan årskurser eller program, men studenter med ytinriktad studiestrategi kommer efter eller hoppar av i större utsträckning än andra. Eftersom det åtminstone går att normalisera studiestrategier är det viktigt att arbeta för att normen är konstruktiv, det vill säga minska inslaget av ytinriktade strategier. De bägge instrumenten korrelerar runt 0,5 med varandra och enstaka frågor går att ifrågasätta, varför tolkningar av enstaka mätningar bör göras med försiktighet.

    Wizard-of-Oz Test of ARTUR - a Computer-Based Speech Training System with Articulation Correction2005Inngår i: proceedings of ASSETS 2005, 2005, s. 36-43Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study has been performed in order to test the human-machine interface of a computer-based speech training aid named ARTUR with the main feature that it can give suggestions on how to improve articulation. Two user groups were involved: three children aged 9-14 with extensive experience of speech training, and three children aged 6. All children had general language disorders. The study indicates that the present interface is usable without prior training or instructions, even for the younger children, although it needs some improvement to fit illiterate children. The granularity of the mesh that classifies mispronunciations was satisfactory, but can be developed further.

    The effect of short formative diagnostic web quizzes with minimal feedback2013Inngår i: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 60, nr 1, s. 234-242Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To help students gauge their understanding of basic concepts and encourage good study habits, we administered short online quizzes that use generic questions in the crucial first few weeks of a course. The purpose of the study was to investigate whether the combination of these web quizzes with generic questions with only binary feedback (right or wrong) would be beneficial for students' learning. We implemented these quizzes in three classes in two different subjects at two different universities, one in Sweden and one in the USA. The students' views on the quizzes' effect on their learning was investigated with surveys and interviews.

    Almost all students appreciated having these quizzes and 38% of them changed their view on how much they knew of the material covered in the course. Furthermore, over 20% of the students reported altering their study habits as a consequence, in particular studying harder or earlier.

    In conclusion, this study indicated that short quizzes using generic questions with limited correct/incorrect feedback on each question, have positive effects when administered early in courses.

    The combination of generic questions and short quizzes could be of value for those contemplating automatic formative assessment, particularly if there is some hesitation with respect to the resources needed for constructing and validating the automatic feedback.

    Feedback in web-based questionnaires as incentive to increase compliance in studies on lifestyle factors2012Inngår i: Public Health Nutrition, ISSN 1368-9800, E-ISSN 1475-2727, Vol. 15, nr 6, s. 982-988Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: We explored the use of feedback in interactive web-based questionnaires for collecting data on lifestyle factors in epidemiological studies.

    Design: Here we report from a cohort study on lifestyle factors and upper respiratory tract infections among 1805 men and women. We introduced interactivity in the form of personalized feedback and feedback on a group level regarding dietary intake, physical activity and incidence of infections in web- based questionnaires as incentives for the respondents to continue answering questions and stay in the study.

    Setting: The study was performed in Sweden.

    Subjects: All participants were randomly selected from the population registry.

    Results: Personalized feedback was offered in the baseline questionnaire and feedback on a group level in the five follow-up questionnaires. In total, 88 % of the participants actively chose to get personalized feedback at least once in the baseline questionnaire. The follow-up questionnaires were sent by email and the overall compliance at each follow-up was 83–84 %, despite only one reminder. In total, 74 % completed all five follow-ups. However, the compliance was higher among those who chose feedback in the baseline questionnaire compared with those who did not choose feedback.

    Conclusions: The results show that it is possible to use feedback in web ques- tionnaires and that it has the potential to increase compliance. The majority of the participants actively chose to take part in the personalized feedback in the baseline questionnaire and future research should focus on improving the design of the feedback, which may ultimately result in even higher compliance in research studies.

    Walking with Seminars2019Inngår i: KTH SoTL 2019, Stockholm: KTH Royal Institute of Technology, 2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background and purpose

    Low levels of physical activity and sedentary behaviour are a growing health problem globally and physical inactivity is associated with increased risk of numerous ailments, cardiovascular disease and mortality. To counteract this, the Walking seminar was invented at KTH in 2015. It is a small step towards a less sedentary lifestyle for students and teachers. Several teachers have already adopted walking seminars, but since it can be perceived as unorthodox, at least before you have tried it yourself, we offer this workshop to give hand-on experience on how to conduct a walking seminar.

    Work done/work in progress

    We started by transforming an on-campus course into a blended course to make sure all participants had accessed the information that would be discussed during the seminar. These walking seminars were evaluated among 131 students and nine teachers leading the walking seminars (Bälter et al. 2018). The responses to the student survey and teacher interviews indicate that discussions, sense of well-being and the general quality of the seminar improved, regardless of how physically active participants were the rest of the time.

    Results/observations/lessons learned

    Students might be sceptical towards a walking seminar, before they have tried it. However, if introduced a day with pleasant conditions, very few are willing to go back to sitting indoors. There is some time lost for the organisation (putting on clothes, dropping of bags, opening doors), but since the discussions outdoors are way more intense than the indoor discussions, this more than makes up for the lost time. The methodology for walking seminars has evolved since its beginning and at this workshop you will get a feel for state-of-the-art when it comes to promoting and arranging a walking seminar.

    Walking Outdoors during Seminars Improved Perceived Seminar Quality and Sense of Well-Being among Participants2018Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 15, nr 303Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Low levels of physical activity and sedentary behaviour are a growing health problem globally. Physical inactivity is associated with increased risk of numerous ailments, cardiovascular disease and mortality. Our primary aim was to perform a feasibility study on how to incorporate physical activity among students and teachers in regular teaching activities. The second aim was to investigate how students and teachers perceived the differences between outdoor walking seminars and regular indoor seminars. By transforming an on-campus course into a blended course, we were able to conduct seminars outdoors in nearby nature while walking. These walking seminars were evaluated among 131 students and nine teachers leading the walking seminars. The responses to the student survey and teacher interviews indicate that discussions, sense of well-being and the general quality of the seminar improved, regardless of how physically active participants were the rest of the time. The study shows one way to increase physical activity with small means; in our case, a reorganization of how we prepared for the seminars which allowed for walking discussions.

    Walking with Seminars2015Inngår i: KTH Scholarship of Teaching and Learning 2015, KTH Royal Institute of Technology, 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Sedentary behavior is a growing health problem in the Western world. According to WHO, physical inactivity is the fourth most common cause of death in the world and behind 6 % of deaths. Students in teaching and learning situations are no exception where for example students from Luleå University of Technology on average sits around 10 hours per day, of which more than 6 hours are when at their university (Dijkstra & Syrén Sandström, 2014).

    There is, therefore, from a public health aspect, reasons to find alternatives to sedentary teaching and learning situations. However, we have gone a step further and looked at opportunities to move also from a learning perspective. For example, "mind- wandering" is very widespread in teaching situations, where studies show that students can focus on average between 3-5 minutes before they lose focus (Rosen, Cheever & Carrier, 2012; Judd & Kennedy, 2011), which increased physical activity could possibly counteract . Furthermore, studies have shown that walking lead to increased creativity Oppezzo & Schwart, 2014).

    In our study, four groups of 5-8 students performed a seminar while walking outdoors with a twofold purpose: to achive the health benefits mentioned above, but also to improve the quality of the seminars. In a questionnaire we examined how students experienced these seminars compared to traditional classroom-based seminars and their perception of communication during the seminars, the overall quality of the workshops and how they felt after the seminars.

    The results are in favour of the walking seminars: the 23 students of 27) who answered the questionnaire report improved communication, sense of well-being and quality and 3 would like to see more such walking seminars at their university.

    The Challenge of Identifying the Importance of Drivers and Barriers for Implementation of Technology Enhanced Learning2018Inngår i: The 11th Pan-Hellenic and International Conference: ICT in Education, 2018, s. 283-290Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The potential of technology enhanced learning (TEL) can have both pedagogical and administrative benefits. In a previous study, we investigated the drivers and barriers for TEL in higher education using Force Field Analysis (FFA). In this follow-up study, we collected new data through a questionnaire to a group of pedagogical developers and at a presentation at a university internal conference for teachers. A Kruskal Wallis test was carried out to test if the groups filling out questionnaire deviated from each other in their ranking. A comparison was also done to the scores in the previous study. As a result of this triangulation, deviations were found between ratings for seven of the 20 identified forces. While the assessments of strengths in FFA is debated, we argue that each group’s view is an important component to understand the situation, and triangulation of data is helpful in understanding the different views.

    Effective Feedback for Faster Learning2019Inngår i: KTH SoTL 2019, Stockholm: KTH Royal Institute of Technology, 2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background and purpose The Open Learning Initiative (OLI) at Carnegie Mellon University and Stanford University showed already in 2008 (Lovett, Meyer & Thille) that by using the OLI methodology, teaching and learning time could be reduced with 50% with maintained results. One key in this methodology is to use online questions with answer-depending feedback. In this workshop we will work with you to formulate OLIinspired questions for your course. Work done/work in progress We have previously worked with online quizzes in several forms (Bälter, Enström & Klingenberg, 2013) and analyzed learning data from OLI courses (Bälter, Zimmaro & Thille, 2018). The online learning material where the questions and feedback is embedded is in campus courses used in flipped classroom settings. In 2017 we ran a pilot of preparatory course in programming based on a Stanford course with OLI methodology in the OpenEdX environment. During the fall semester 2018 questions with answer-depending feedback was added to the course material in an online introductory programming course given in Canvas at KTH. Results/observations/lessons learned While a full implementation of the entire OLI methodology requires infrastructure that is not in place at KTH yet (event handler, analytic engine), the actual learning for the students takes place in the interaction with the questions and their feedback and this part can already be implemented in Canvas at KTH. Take-home message Well-formulated questions with forward focused feedback can dramatically speed up both teaching and 1 2 1 1 2 Page 25 KTH SoTL 2019 (A-K) learning. This workshop brings that speed to your course with practical exercises based on your own course.

    Abstract [en]

    Many email users, especially managers, receive too many email messages to read in the time available to them. The solutions available today often require programming skills on the part of the user to define rules for prioritizing messages or moving messages to folders. We propose a different approach: categorize messages in the inbox with predefined rules that do not require maintenance and are scalable to handle anything from 50 to thousands of messages

    Estimating the minimum number of opportunities needed for all students to achieve predicted mastery2018Inngår i: Smart Learning Environments, E-ISSN 2196-7091, Vol. 5, nr 15Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We have conducted a study on how many opportunities are necessary, on average, for learners to achieve mastery of a skill, also called a knowledge component (KC), as defined in the Open Learning Initiative (OLI) digital courseware. The study used datasets from 74 different course instances in four topic areas comprising 3813 students and 1.2 million transactions. The analysis supports our claim that the number of opportunities to reach mastery gives us new information on both students and the development of course components. Among the conclusions are a minimum of seven opportunities are necessary for each knowledge component, more if the prior knowledge among students are uneven within a course. The number of KCs in a course increases the number of opportunities needed. The number of opportunities to reach mastery can be used to identify KCs that are outliers that may be in need of better explanations or further instruction.

    Moving Technology-Enhanced-Learning Forward: Bridging Divides through Leadership2017Inngår i: International Review of Research in Open and Distributed Learning, Vol. 18, nr 3, s. 167-177Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A study of academics and professional staff engaged in the emerging field of Technology Enhanced Learning (TEL) reveal three areas of significant difference in reference to perspectives about TEL. These differences rest on the following individual characteristics: 1) research areas and competencies, 2) academic level, and 3) attitudes towards teaching. While the number of respondents is small, the data set is rich due to a diverse group of respondents. Leadership strategy that rests on appreciative inquiry to draw these perspectives together could begin with implementation of five ways of working collaboratively: acknowledge unique skills different from one’s own, understand driving forces from different vantage points, learn enough about other views to show respect, identify common goals and incentives for all, and include people from all relevant groups.

    Student Approaches to Learning in Relation to Online Course Completion2013Inngår i: Canadian Journal of Higher Education, ISSN 0316-1218, Vol. 43, nr 3, s. 1-18Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study investigates the relationship between approaches to studying and course completion in two online preparatory university courses in math- ematics and computer programming. The students participating in the two courses are alike in age, gender, and approaches to learning. Four hundred and ninety-three students participating in these courses answered the short version of the Approaches and Study Skills Inventory for Students (ASSIST). Results show that students demonstrating a deep approach to learning in ei- ther course are more likely to complete. In the mathematics course, a com- bination of deep and strategic approaches correlates positively with course completion. In the programming course, students who demonstrate a surface approach are less likely to complete. These results are in line with the inten- tions of the course designers, but they also suggest ways to improve these courses. Furthermore, the study demonstrates that ASSIST can be used to evaluate course design.

    Keystroke-level analysis to estimate time to process pages in online learning environments2018Inngår i: Interactive Learning Environments, ISSN 1049-4820, E-ISSN 1744-5191, Vol. 26, nr 4, s. 476-485Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is challenging for students to plan their work sessions in online environments, as it is very difficult to make estimates on how much material there is to cover. In order to simplify this estimation, we have extended the Keystroke-level analysis model with individual reading speed of text, figures, and questions. This was used to estimate how long students might take to work through pages in an online learning environment. The estimates from the model were compared to data collected from 902 volunteer students. Despite the huge differences in reported reading speeds between students, the presented model performs reasonably well and could be used to give learners feedback on how long it takes to work through pages in online learning environments. This feedback could be used to support students’ motivation and effort regulation as they work through online course components. Although the model performs reasonably well, we propose giving feedback in the form of intervals to indicate the uncertainty of the estimates.

    Abstract [en]

    Student engagement is crucial for successful self-paced learning. Feeling isolated during self-paced learning with neither adequate supervision nor intervention by teachers may cause negative emotions such as anxiety. Such emotions may in turn significantly weaken students' motivation to engage in learning activities. In this paper, we develop a self-paced learning environment (FishBuddy) that aims to reduce anxiety and promote student engagement. We construct and implement a physiologically-state-aware performance-evaluation model for identifying potentially fruitful moments of intervention when students show frustration during learning activities using an Apple Watch application that measures heart rate and alerts the student to watch a visualization of his or her own physiological state. We have conducted an experiment with 20 first-year undergraduate students, randomly separated into an experimental group and a control group, who carry out online, self-paced English grammar exercises. The students in the experimental group used FishBuddy and those in the control group did not. The self-reports from both groups show that FishBuddy significantly reduced reported experiences of anxiety and isolation in the experiment. Further to this, students who used FishBuddy were engaged longer with the exercises. The average scores on the exercises between the two groups, however, were not significantly different.

    Relative Validity of Micronutrient and Fiber Intake Assessed With Two New Interactive Meal- and Web-Based Food Frequency Questionnaires2014Inngår i: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 16, nr 2, s. e59-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The meal-and Web-based food frequency questionnaires, Meal-Q and MiniMeal-Q, were developed for cost-efficient assessment of dietary intake in epidemiological studies. Objective: The objective of this study was to evaluate the relative validity of micronutrient and fiber intake assessed with Meal-Q and MiniMeal-Q. The reproducibility of Meal-Q was also evaluated. Methods: A total of 163 volunteer men and women aged between 20 and 63 years were recruited from Stockholm County, Sweden. Assessment of micronutrient and fiber intake with the 174-item Meal-Q was compared to a Web-based 7-day weighed food record (WFR). Two administered Meal-Q questionnaires were compared for reproducibility. The 126-item MiniMeal-Q, developed after the validation study, was evaluated in a simulated validation by using truncated Meal-Q data. Results: The study population consisted of approximately 80% women (129/163) with a mean age of 33 years (SD 12) who were highly educated (130/163, 80% with >12 years of education) on average. Cross-classification of quartiles with the WFR placed 69% to 90% in the same/adjacent quartile for Meal-Q and 67% to 89% for MiniMeal-Q. Bland-Altman plots with the WFR and the questionnaires showed large variances and a trend of increasing underestimation with increasing intakes. Deattenuated and energy-adjusted Spearman rank correlations between the questionnaires and the WFR were in the range rho=.25-.69, excluding sodium that was not statistically significant. Cross-classifications of quartiles of the 2 Meal-Q administrations placed 86% to 97% in the same/adjacent quartile. Intraclass correlation coefficients for energy-adjusted intakes were in the range of .50-.76. Conclusions: With the exception of sodium, this validation study demonstrates Meal-Q and MiniMeal-Q to be useful methods for ranking micronutrient and fiber intake in epidemiological studies with Web-based data collection.

    Two New Meal- and Web-Based Interactive Food Frequency Questionnaires: Validation of Energy and Macronutrient Intake2013Inngår i: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 15, nr 6, s. e109-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Meal-Q and its shorter version, MiniMeal-Q, are 2 new Web-based food frequency questionnaires. Their meal-based and interactive format was designed to promote ease of use and to minimize answering time, desirable improvements in large epidemiological studies. Objective: We evaluated the validity of energy and macronutrient intake assessed with Meal-Q and MiniMeal-Q as well as the reproducibility of Meal-Q. Methods: Healthy volunteers aged 20-63 years recruited from Stockholm County filled out the 174-item Meal-Q. The questionnaire was compared to 7-day weighed food records (WFR; n=163), for energy and macronutrient intake, and to doubly labeled water (DLW; n=39), for total energy expenditure. In addition, the 126-item MiniMeal-Q was evaluated in a simulated validation using truncated Meal-Q data. We also assessed the answering time and ease of use of both questionnaires. Results: Bland-Altman plots showed a varying bias within the intake range for all validity comparisons. Cross-classification of quartiles placed 70%-86% in the same/adjacent quartile with WFR and 77% with DLW. Deattenuated and energy-adjusted Pearson correlation coefficients with the WFR ranged from r=0.33-0.74 for macronutrients and was r=0.18 for energy. Correlations with DLW were r=0.42 for Meal-Q and r=0.38 for MiniMeal-Q. Intraclass correlations for Meal-Q ranged from r=0.57-0.90. Median answering time was 17 minutes for Meal-Q and 7 minutes for MiniMeal-Q, and participants rated both questionnaires as easy to use. Conclusions: Meal-Q and MiniMeal-Q are easy to use and have short answering times. The ranking agreement is good for most of the nutrients for both questionnaires and Meal-Q shows fair reproducibility.

    Pronunciation feedback from real and virtual language teachers2007Inngår i: Computer Assisted Language Learning, ISSN 0958-8221, E-ISSN 1744-3210, Vol. 20, nr 3, s. 235-262Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this paper is to summarise how pronunciation feedback on the phoneme level should be given in computer-assisted pronunciation training (CAPT) in order to be effective. The study contains a literature survey of feedback in the language classroom, interviews with language teachers and their students about their attitudes towards pronunciation feedback, and observations of how feedback is given in their classrooms. The study was carried out using focus group meetings, individual semi-structured interviews and classroom observations. The feedback strategies that were advocated and observed in the study on pronunciation feedback from human teachers were implemented in a computer-animated language tutor giving articulation feedback. The virtual tutor was subsequently tested in a user trial and evaluated with a questionnaire. The article proposes several feedback strategies that would improve the pedagogical soundness of CAPT systems.

    Designing the user interface of the computer-based speech training system ARTUR based on early user tests2006Inngår i: Behavior and Information Technology, ISSN 0144-929X, E-ISSN 1362-3001, Vol. 25, nr 4, s. 353-365Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study has been performed in order to evaluate a prototype for the human - computer interface of a computer-based speech training aid named ARTUR. The main feature of the aid is that it can give suggestions on how to improve articulations. Two user groups were involved: three children aged 9 - 14 with extensive experience of speech training with therapists and computers, and three children aged 6, with little or no prior experience of computer-based speech training. All children had general language disorders. The study indicates that the present interface is usable without prior training or instructions, even for the younger children, but that more motivational factors should be introduced. The granularity of the mesh that classifies mispronunciations was satisfactory, but the flexibility and level of detail of the feedback should be developed further.

    The activity of human metadata creation and the Semantic Web2015Inngår i: International Journal of Metadata, Semantics and Ontologies, ISSN 1744-263X, Vol. 10, nr 2, s. 64-74Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents an explorative study of the human activity of creating metadata, done with the purpose of exploring the practices of this activity and how those can potentially impact the utility of the metadata as it is exposed on a level that enables semantic collaboration, like the Semantic Web. Previous research around human metadata creation seems to indicate that how the activity is carried out has a common core, but is unique in each situation on how it can be improved. The data for this study was gathered through interviews and analyzed using activity theory. The analysis of the data gathered through the interviews indicate that the main objective of the activity is to enable discovery within a collection. Metadata is however created with a community of users in mind, which is sometimes reflected in metadata creation guidelines. These guidelines can in turn impact the discoverability across these communities as metadata is exposed on the Semantic Web.
