Available in Afrikaans only Die navorsingsverslag dokumenteer die instruksionele ontwerpproses van 'n rekenaar gesteunde tutoriaal (RGT), "Random Variables", een van 'n reeks van nege soortgelyke tutoriale wat as aanvulling tot die geskrewe studiegids vir 'n eerstejaar kursus in Statistiek by die Universiteit van Suid?Afrika (Unisa) gebruik word. Die instruksionele benadering wat in die RGT gebruik is, probeer om kognitiewe ondersteuning te verskaf en om 'n intuitiewe begrip van abstrakte konsepte aan te moedig. Die doel is om die geisoleerdheid waarin afstandsonderrig studente verkeer, te verlig en om groter interaktiwiteit met die studiemateriaal tot stand te bring. Formatiewe evaluering het 'n sentrale plek in die instruksionele ontwerpmodel, wat analise, ontwerp, onwikkeling en implementering insluit, ingeneem. Die formatiewe evaluering is in vier mikro?stadia, naamlik vakkundige resensie, prototipe, loodstoetsing en veldtoetsing gedoen. Die navorsingsresultate het daartoe gelei dat die tutoriale as sulks verbeter is. Dit kan ook verdere navorsing op die gebied van summatiewe evaluering rig en lei. Die navorsingsverslag moet saamgelees word met die loop van die program "Random Variables", wat op disket beskikbaar is. / Thesis (PhD)--University of Pretoria, 2002. / Humanities Education / PhD / Unrestricted

This dissertation is the developmental research report on the design and development of a multimedia tutorial on Anthropometry for university-level health science students. The practical implication of using Merrill's Model of Instructional Design for developing course work for senior students in the health sciences was investigated. The multimedia tutorial was designed and developed, and the prototype evaluated by a team consisting of subject and education experts. The prototype was tested by third-year dietetic students who had completed the lecture-based and paper-based course. The students were observed while using the program, then completed a structured questionnaire and finally were given the opportunity to express their views in an informal group discussion. It was found that if the activation of relevant existing knowledge does not take place, Merrill's Model will be turned inside-out: the student's own problem replaces the instructional problem. / Thesis (MEd (Computer-integrated Education))--University of Pretoria, 2003. / Social Studies Education / unrestricted
