Modeling the user knowledge by belief networks

This paper describes the user modeling component of EPIAIM, a consultation system for data analysis in epidemiology. The component is aimed at representing knowledge of concepts in the domain, so that their explanations can be adapted to user needs. The first part of the paper describes two studies aimed at analysing user requirements. The first one is a questionnaire study which examines the respondents' familiarity with concepts. The second one is an analysis of concept descriptions in textbooks and from expert epidemiologists, which examines how discourse strategies are tailored to the level of experience of the expected audience. The second part of the paper describes how the results of these studies have been used to design the user modeling component of EPIAIM. This module works in a two-step approach. In the first step, a few trigger questions allow the activation of a stereotype that includes a "body" and an "inference component". The body is the representation of the body of knowledge that a class of users is expected to know, along with the probability that the knowledge is known. In the inference component, the learning process of concepts is represented as a belief network. Hence, in the second step the belief network is used to refine the initial default information in the stereotype's body. This is done by asking a few questions on those concepts where it is uncertain whether or not they are known to the user, and propagating this new evidence to revise the whole situation. The system has been implemented on a workstation under UNIX. An example of functioning is presented, and advantages and limitations of the approach are discussed.

Curriculum theory, curriculum policy and the problem of ill-disciplined thinking

This paper examines the implications of policy fracture and arms length governance within the decision making processes currently shaping curriculum design within the English education system. In particular it argues that an unresolved ‘ideological fracture’ at government level has been passed down to school leaders whose response to the dilemma is distorted by the target-driven agenda of arms length agencies. Drawing upon the findings of a large scale on-line survey of history teaching in English secondary schools, this paper illustrates the problems that occur when policy making is divorced from curriculum theory, and in particular from any consideration of the nature of knowledge. Drawing on the social realist theory of knowledge elaborated by Young (2008), we argue that the rapid spread of alternative curricular arrangements, implemented in the absence of an understanding of curriculum theory, undermines the value of disciplined thinking to the detriment of many young people, particularly those in areas of social and economic deprivation.

Developing international business managers through international study visits to China

Globalization is a key factor in the success of business organizations today, impacting many aspects of management performance. Understanding the global business environment has therefore become a key objective in the teaching of international business on Executive MBA programs. Drawing on the theory of experiential learning, this study examines the relationship between program structure and learning activities of an international study visit (ISV) to China and the learning experience for Executive MBA students. The findings indicate that learning experience may be most effective where the structure of an ISV incorporates certain activities that promote experiential and deep-level learning. Educational implications are discussed.

”Det är ju troligen inte en overheadapparat de kommer att använda sig av i framtiden…” : Om skolans tekniksprång, en undersökning om datorns användning på gymnasiet

The aim of this qualitative respondent investigation is to delve into the various views that teachers have concerning the “One-to-One project”, as well as the use of computers as an aid in teaching. One-to-One means that teachers and students will be equipped with a laptop they can use at home and at school.This essay looks at how several factors have changed as a result of this. These factors are threefold: the role of the teacher, the teaching experience, and the student´s learning process. In order to answer the mentioned questions, four interviews have been conducted at two different high schools in southern Norrland. The theory used is the socio-cultural perspective. One result has been that computers can simplify teaching in various ways. Students have faster access to information, and there exists a platform for further communication between the teacher and student outside the classroom. However, there are also several negative aspects. One of these is that the students spend time doing non-school related activities, such as interacting using social mediums. Results also show that the role of the teacher has due to the "One-to-One project" gone from being structural to being interactional. The conclusions reached by the investigation are that today’s schools are experiencing a paradigm shift. Old teaching methods are being replaced by new methods and an altered teaching practice has developed as a result of the presence of the computer in the classroom.

À la recherche des facteurs de réussite au lycée : Apprentissage de langues en ligne au lycée - une étude

The aim of this academic essay is to research into Distance teaching in language education at a comprehensive upper high school in a region in Sweden. Qualitative and quantitative studies are combined by using evaluation and interview methods with students who have completed their studies and with those who have decided to terminate them 2012/2013. The goals are to identify success factors and elements in devising and compiling on-line language courses thus eliminating failure by students unable / choosing not to complete courses. Present Distance teaching is mostly applicable for the already motivated students and research shows that measures can be taken to increase the percentage of successful and satisfied students.

Undersökande arbetssätt i NO-undervisningen i grundskolans tidigare årskurser

This thesis deals with the use of inquiry-based approaches in primary school science. The aim is to investigate the goals and purposes that are constituted by the curriculum and by the teachers in interviews and through their teaching in the classroom. The results are used to develop conceptual tools that can be used by teachers’ in their work to support students’ learning of science when using an inquiry-based approach. The thesis is comprised of four papers. In paper one a comparative analysis is made of five Swedish national curricula for compulsory school regarding what students should learn about scientific inquiry. In paper two 20 teachers were interviewed about their own teaching using inquiry. Classroom interactions were filmed and analyzed in papers three and four, which examine how primary teachers use the various activities and purposes of the inquiry classroom to support learning progressions in science. The results of paper one show how the emphasis within and between the two goals of learning to carry out investigations and learning about the nature of science shifted and changed over time in the different curricula. Paper two describes the selective traditions and qualities that were emphasized in the teachers’ accounts of their own teaching. The results of papers three and four show how students need to be involved in the proximate and ultimate purposes of the teaching activities for progression to happen. The ultimate purposes are the scientific purposes for the lesson (as given by the teacher or by the curriculum), whereas the proximate purposes are the more student-centered purposes that through different activities should allow the students to relate their own experiences and language to the ultimate purpose. The results show the importance of proximate purposes working as ends-in-viewin the sense of John Dewey, meaning that the students see the goal of the activity and that they are able to relate to their experiences and familiar language.

Klassrumsinteraktion i de tidiga skolåren : flerspråkiga elever i skolans språkliga vardag

Classroom interaction is particularly important for those students who learn school knowledge in a second language. In this article two episodes of whole class teaching in pre-school and standard one are analyzed. The analysis shows the importance of making teachers aware of interactional patterns in classrooms. Although knowledge was presented clearly and concretely and teachers used routines that made norms explicit, inconsistencies in interactional patterns made the role of the teacher stand out as unclear. Whole class teaching of this type does not provide students with such linguistic and intellectual demands that are necessary for their language development.

"Men skolan kan inte bara lägga sig platt på rygg" : Attityder till värdegrundsarbetet inom vuxenutbildningen

Syftet med denna studie är att belysa attityder som finns hos lärare i svenska för invandrare (SFI) och svenska som andraspråk (SVA) till integreringen av värdegrundsuppdraget i vuxenutbildningen och i det sammanhanget även uppmärksamma deras berättelser om yrkesetiska konflikter som de upplevt i värdegrundsarbetet. Studien söker att svara på följande frågeställningar: Hur definierar SFI- och SVA-lärarna vuxenutbildningens värdegrund? Hur förhåller sig lärarna till integreringen av värdegrundsfrågor i undervisningen? På vilket sätt integrerar SFI- och SVA-lärarna värdegrundensmålen i sin dagliga verksamhet? Vilka svårigheter möter lärarna och vilka yrkesetiska konflikter uppstår i deras arbete med värdegrundsfrågor? och Vad styrs lärarna av när de löser yrkesetiska konflikter som uppstår i värdegrundsarbetet? Metoden som används i undersökningen är kvalitativ och bygger på intervjuer med totalt sex SFI- och SVA-lärare. Intervjuerna kompletteras med en enkätundersökning som genomförts med samma lärare. Studiens resultat diskuteras utifrån en teori om sociala attityder och dess antagande att individers kunskaper om, och positiva känslor till, en social företeelse kommer att manifesteras i deras handlingar. Resultatanalysen visar att SFI- och SVA-lärarna förknippar skolans värdegrund med demokrati, jämställdhet mellan kvinnor och män, alla människors lika värde och trygg inlärningsmiljö och har ett positivt förhållningssätt till värdegrundsarbetet, som de medvetet integrerar i språkundervisningen.

Lärares syn på undervisning i närområdet utanför klassrummet : En intervjustudie om hur lärare ser på undervisning som sker i närområdet utanför klassrummet inom de samhällsorienterande ämnena i årskurs 1-3

Syftet med studien var att ta reda på hur lärare ser på närområdet och hur de bedriver undervisning i närområdet utanför klassrummet inom de samhällsorienterande ämnena i årskurs 1-3. Vidare var syftet att undersöka vad lärare hade för åsikter om undervisningens inverkan på elevers lärande i årskurs 1-3 samt vad de såg för möjligheter och problem med undervisningsformen. För att besvara studiens syfte intervjuades sex lärare genom semistrukturerade intervjuer. Intervjuerna analyserades med en innehållsanalys där mönster söktes i informanternas svar. Resultatet visade att samtliga lärare anser att undervisning i närområdet utanför klassrummet har en positiv inverkan på elevers lärande men att alla lärare inte bedriver undervisning i denna form. Problem som hindrar lärare från att bedriva undervisning i närområdet är tids- och ekonomibrist samt bristen på forskning inom ämnet och vissa lärare saknar även viljan till att bedriva undervisning på detta sätt. I resultatet presenteras även några olika exempel på hur lärare undervisar i närområdet utanför klassrummet och vad de ser för möjligheter med denna undervisningsform.

L’image comme outil didactique dans l’enseignement du français dans des collèges et des lycées en Suède

Le travail actuel a été rédigé dans le but d’éclaircir en quoi consiste le rôle de l’image comme outil didactique aux cours de français aux collèges et aux lycées suédois. Nous avons abordé notre thème sous des perspectives différentes : d’un côté, nous avons analysé les images dans deux livres, puisque les manuels font souvent partie de chaque leçon de français ; de l’autre côté, nous avons fait un questionnaire que nous avons distribué aux professeurs à travers les médias sociaux et par email. Nous avons également étudié les données récoltées aux cours des entretiens avec trois professeurs de français au lycée suédois, pour savoir comment les professeurs intègrent des images dans la pratique. Selon les résultats de notre étude, il nous a été possible d’affirmer que l’image est un outil qui n’est pas omniprésent, mais qui est parfois utilisé afin de rendre les leçons plus variées. La photographie est le type d’image le plus répandu dans la pratique des professeurs et dans les manuels ; le format numérique est le plus fréquent en tenant en compte de la révolution technologique et de l’habitude des jeunes à travailler avec les ordinateurs. Cependant, l’image n’est pas un outil indépendant. Elle est très souvent complétée par d’autres outils didactiques et sert principalement à accompagner la lecture, à développer l’expression orale et le vocabulaire et aussi à illustrer des phénomènes culturels. En conclusion, il ressort de notre mémoire, qu’il est important que le professeur accompagne le travail avec des images avec des instructions et des commentaires, afin de rendre l’apprentissage plus efficace.

Degree projects improving co-operation between the teacher education program and schools : - Swedish experiences

In 1977, when teacher education inSwedenwas incorporated into the university system, the main reason was to transform it into an academic tradition. Now, nearly 30 years later, there is still tension between the academic and the vocational tradition; they show up as different and separated elements in a program that is meant to prepare students for a career as a teacher and for a possible future career as a researcher in this field. This tension gives rise to a risk of allowing parallel “tracks” to develop and of isolating the degree thesis work from other courses. On the teacher-training program in which we are involved, close co-operation with partner-schools, where the practical part of the program takes place, has been established. Here, the students´ degree theses are an important factor in making this co-operation work on a concrete level. Accordingly, the purpose of the degree thesis is both to reflect problems in schools and contribute to better teaching in the individual school, but also to offer relevant educational subject matter to the students, which may be adapted as an element in the university’s research environments. From these points of view, the degree thesis is an important part of teacher education and rather more than just a single course. The degree thesis should be an element that gives the students an opportunity to show that they have reached central goals in the teacher education program. It should also be an integral part in the development of critical and scholarly thinking, deepening pedagogical and didactic knowledge and giving the students an opportunity to apply research methods. We will here use two minor case studies: one that compares teacher education programs in five Swedish universities and one minor study at one of those universities, in order to elaborate on the questions: - What purpose has a degree thesis and what role does it play in teacher education? - What criteria are relevant to assessing a degree thesis and what qualities do the degree theses have? - Is it possible to assess a degree thesis fairly and what happens to students who do not pass? - How could the degree thesis be used to improve the contact between the teacher education program and its partner schools in order to contribute to the development of the individual school?
