This research project report discusses the development of a commercial, consignment-based library (a) of reusable software components to be accessed using the World-Wide Web. The research project consists of two parts: the development of a prototype system that provides interface and information retrieval functionality for such a system, and an analysis of the technical and business issues involved in making the library operational as a commercial entity. <p>The prototype system uses a hypertext browser and a query-based search mechanism to access descriptions of reusable software components; these descriptions are structured by a variation of a faceted classification system. The issues addressed include the classification and description of reusable software components; methods of retrieval, especially library browsing methods based on component classification; and analysis of incentives for reuse. / Master of Science

Magistro darbo objektas – mokomųjų kompiuterinių priemonių leidyba. Darbo tikslas – ištirti lietuviškų mokomųjų kompiuterinių priemonių leidybos procesą, pasiūlą ir ją įtakojančius veiksnius. Pagrindiniai darbo uždaviniai: išanalizuoti MKP gamybos procesą; išanalizuoti Lietuvoje leidžiamų MKP pasiūlą; sudaryti lietuviškų originalių MKP sąrašą; ištirti MKP leidybą labiausiai įtakojančius veiksmus; ištirti MKP platinimo veiksnius, analizuojant pasirinktos leidyklos atvejį. Naudojantis informacijos paieškos ir sisteminimo, dokumentų analizės, anketiniu ir lyginamuoju metodais, prieita prie išvados, kad MKP yra viena iš svarbiausių skaitmeninių mokymo priemonių. MKP sujungia vaizdinę, garsinę ir tekstinę informaciją, ko negalima padaryti jokioje kitoje mokymo priemonėje. Taip pat šios priemonės gali būti interaktyvios, kas padeda mokiniui geriau įsisavinti medžiagą ir mokymosi procesą daro įdomesniu. Darbe pateikiamas lietuviškų MKP sąrašas, kuriame suregistruotos originalios lietuviškos MKP, skirtos arba tinkamos naudoti bendrojo lavinimu mokyklose. Ištyrus MKP pasiūlą Lietuvoje galima teigti, kad mokyklose vienodai naudojamos originalios lietuviškos, adaptuotos ir užsienio šalių sukurtos kompiuterinės priemonės. Valstybė, vykdydama švietimo politiką skatina kurti originalias, bendrojo lavinimo mokyklų programoms pritaikytas MKP. Mokykloms daugiausiai sukurta lietuvių kalbos ir istorijos disciplinoms pritaikytų priemonių. Šių priemonių leidybą stipriai įtakoja mokinių...

The aim is to investigate the process of Educational Software publishing, its supply and factors that influence it. Major goals of the study: analysis of Educational Software production process; analysis of Educational Software supply published in Lithuania; provide a list of Lithuanian Educational Software list; analysis of most influential factors of Educational Software publishing; analysis of Educational Software promotion factors, choosing one publishing house. Keywords: Educational software, Educational Software research, Educational Software classification, study of teachers work with Educational Software, Educational Software distribution, Educational Software promotion. After information search and systematization, analysis of documents, usage questionnaire and comparative survey methods, findings show that Educational Software is one of the most important digital educational means. Educational Software comprises video, audio and textual information which can not be achieved by other educational means. As well these means can be interactive which helps students learn material better and learning process becomes more interesting. This study includes a list of original Lithuanian Educational Software which is designed and appropriate for secondary school use. After investigation of Educational Software supply in Lithuania we can assume that schools use original Lithuanian and adapted foreign software... [to full text]

Cette thèse questionne l'enseignement de la proportionnalité à des élèves de 11 à 16 ans relevant de l'adaptation scolaire et de la scolarisation des élèves handicapés. Les travaux de didactique des mathématiques ont montré l'inaboutissement fréquent du projet d'appropriation de la proportionnalité auprès des élèves jusqu'au collège, et tout particulièrement en ASH.Afin de savoir si une adaptation peut se faire sans dénaturer le savoir, nous proposons donc une progression sur l'enseignement de la proportionnalité en classe de Quatrième SEGPA.Nous insistons sur l'importance de l'organisation des savoirs au sein de cette progression et sur la pertinence des contextes et des valeurs des variables didactiques numériques. Les analyses de nos observations se font dans le cadre de l'analyse statistique implicative, de la Théorie des Situations Didactiques ainsi que de la double approche utilisée dans l'analyse des pratiques des enseignants.La mise en œuvre de la progression construite nécessite pour les enseignants des connaissances mathématiques. Afin de réactiver ces connaissances, nous proposons des représentations symboliques qui illustrent les techniques de résolution de problèmes relevant de la proportionnalité simple. / The purpose of this thesis is to investigate the teaching of proportionality to 11 to 16-year old pupils registered in special-needs schools including pupils with more severe learning disabilities.Studies related to the teaching of mathematics have shown that the understanding of proportionality by pupils up to middle school age and more particularly by children with significant learning difficulties is often inappropriate. In order to find out if an adjustment can be made without any impact on the knowledge requirements, we experimented a teaching plan concerning the learning of proportionality by children with special-needs in the context of our study. We insist on the importance of the organization of the different types of knowledge within this teaching plan and also on the relevance of backgrounds and values of numerical didactical parameters. Analysis of our observations is carried out with statistical implicative analysis, Theory of Didactical Situations and with the frame of the double approach used to analyse the practices of teachers.The implementation of such a teaching plan requires, for teachers, mathematical knowledge. In order to reactivate this knowledge, we propose a symbolic scheme for each resolving technique applied to problems involving direct proportionality.
