The present study assessed the views of students on school-related determinants with respect to liking or disliking technology. In determining students' views, two self-report instruments, the Classroom Learning Environment Survey (CLES) and Attitudes Toward Science Scale (ATSS) were used. Also, an interview schedule was arranged with a selected group. Participants were 200 first years registered for Diplomas in Primary -, Secondary -, and Technology Education. Results indicated a positive relationship between attitudes towards technology and each of teacher characteristics, student characteristics and the classroom environment. Regression analysis showed that attitudes toward technology were predicted by the three study variables. On the other hand, no statistically significant gender differences were established. Recommendations and suggestions for further research are also advanced. / Mathematics, Science & Technology Education / M. Sc. (Technology Education)

M.Ed. (Media Studies) / Despite the availability I variety and virtually limitless properties of the different types of educational materials and equipment, it would appear that there are still many teachers who are opposed to the use of educational media. For the purposes of this study it was necessary to investigate the reasons why teachers do not use educational materials and equipment during their lessons. A literature study was done to investigate the factors which could contribute to resistance I the areas where resistance could appear and resistance of teachers to the use of media in their classrooms. An empirical study was conducted into the possible reasons for resistance to media usage at East Rand high schools. Research yielded the following results: The majority of teachers are willing to discuss media related matters with colleagues and superiors. Teachers are willing to experiment with a variety of media. The majority are willing to change their methods and use the ideas of others in their own classrooms.

M.Ed. / Students exhibit misconceptions or deviations from universally accepted concepts. Constructivists trace these misconceptions back' to the unique conceptual frames of reference of students. Ausubel (1985:82) named prior knowledge as the single most important factor influencing learning. New teaching strategies were designed to prevent or eliminate these misconceptions. The strategies are based on guidelines postulated by researchers such as Posner and his co-workers (1982:211). Several strategies use media to motivate students or provide a more concrete base for concept formation. The side effects of the utilization of media are important to designers and users of media. An empirical investigation was launched to determine whether media could also stimulate the formation of misconceptions. The investigation indicated that two dimensional representations of atoms, molecules and ion lattices can lead to misconceptions. Greater care should be taken in the selection of illustrations for textbooks and other media. If these side effects are taken into account by media designers and teachers, media can play a major role in the prevention and elimination of misconceptions.

Thesis (MEd)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis explores the use of educational technologies in grades 10 to 12 life sciences classrooms at a local high school. I argue that the application of educational technologies in science classrooms has the potential to engender critical teaching and learning, and to contribute to professional development. By reflecting on my own professional development as a science teacher over the past three years (2008-2010), I show that the use of educational technologies cultivates moments of critical pedagogy that link strongly with reflective teaching, critical thinking and transformative learning. Drawing on two intertwined narratives, I show how educational technologies can enhance reflective teaching whereby, firstly, teachers can take seriously theories and expertise in their practices; secondly, organise their classrooms so as to facilitate critical learning; and, thirdly, take up broader institutional and social issues. In addition, I show that the use of educational technologies opens up pedagogical spaces for critical thinking and transformative learning – that is, whereby learners learn creatively, actively, engagingly and reflecting on their own practices. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die gebruik van onderwystegnologie in grade 10 tot 12 lewenswetenskapklaskamers by ʼn plaaslike hoërskool. Ek argumenteer dat die toepassing van onderwystegnologie in wetenskapklaskamers die potensiaal het om kritiese onderrig en leer teweeg te bring, en ʼn bydrae tot professionele ontwikkeling te maak. Deur te reflekteer op my eie professionele ontwikkeling as ʼn wetenskaponderwyser oor die afgelope drie jaar (2008-2010), dui ek aan hoedat die gebruik van onderwystegnologie krities pedagogiese oomblikke kultiveer wat sterk aanklank vind by reflektiewe onderrig, kritiese denke en transformatiewe leer. Met betrekking tot twee narratiewe dui ek aan hoedat onderwystegnologie reflektiewe onderrig kan bevorder deurdat, eerstens, onderwysers teorieë en kundighede in hulle gebruike ernstig opneem; tweedens, klaskamers organiseer om kritiese leer te fasiliteer; en derdens, breër institusionele en sosiale kwessies aanspreek. Daarenbowe dui ek aan hoedat onderwystegnologie ook pedagogiese ruimtes vir kritiese denke en transformatiewe leer bied – dit is, waarby leerders kreatief, aktief en betrokke is, en op hulle eie praktyke reflekteer.

A report issued in 2012 by the United States Government Accountability Office (US Government Accountability Office, 2012) concluded that the United States is not producing enough graduates in Science, Technology, Engineering, and Mathematics (STEM) to meet the demands of its economy. According to the National Center for Educational Statistics (2001), fewer than fifty percent of students nationally possess a solid command of mathematical content. This study tested whether the insertion of Academic Service Learning (ASL) into intermediate algebra courses improved students’ performance, their motivation to learn the subject, and attitudes towards mathematics learning. ASL is an educational strategy that integrates meaningful community service with instruction and reflection to enrich the learning experience, teach civic responsibility, and strengthen communities (Duffy, Barrington, West, Heredia, & Barry, 2011). The subjects in this study were thirty-four students enrolled in intermediate algebra at a large public university in southeast Florida. The participant group consisted of fifteen students who completed the requirements of the ASL program and the comparison group consisted of nineteen students who initially showed interest in the program but dropped out of the study early in the semester. Through a mixed method analysis, the study found that the proportion of students who passed the course in the ASL group was greater than the proportion of students in the non-ASL group. Similarly, the mean final course grade in the ASL group was higher than the mean final course grade in the non-ASL group. The results of the qualitative analyses showed that all the participants enjoyed the ASL experience. In addition, some participants felt that the ASL project raised their motivation to learn mathematics and increased their competence in mathematics. However, both quantitative and qualitative analyses revealed that the students’ participation in the ASL project did not affect their attitudes towards mathematics learning. The study concluded that Academic Service Learning has the potential to help improve students’ success rates in developmental mathematics courses as well as increase their motivation to learn the subject. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Despite widespread use of web-based e-learning applications, insufficient attention is paid to their usability. There is a need to conduct evaluation using one or more of the various usability evaluation methods. Given that heuristic evaluation is known to be easy to use and cost effective, this study investigates the extent to which it can identify usability problems in a web-based e-learning application at a tertiary institution. In a comparative case study, heuristic evaluation by experts and survey evaluation among end users (learners) are conducted and the results of the two compared. Following literature studies in e-learning - particularly web-based learning - and usability, the researcher generates an extensive set of criteria/heuristics and uses it in the two evaluations. The object of evaluation is a website for a 3rd year Information Systems course. The findings indicate a high correspondence between the results of the two evaluations, demonstrating that heuristic evaluation is an appropriate, effective and sufficient usability evaluation method, as well as relatively easy to conduct. It identified a high percentage of usability problems. / Computing / M.Sc. (Information Systems)

The use of interactive e-learning tutorials is an effective form of teaching and learning. It is therefore important that attention is paid to their usability. This research relates to the evaluation of a CD-based e-learning tutorial for learning Business English, with the aims of investigating its usability and identifying problems. Particular attention is paid to aspects that hinder the learner from achieving the learning objectives. The study uses two usability evaluation methods (UEMs), namely controlled usability testing in an HCI laboratory and a user questionnaire survey. The main aim of the study is to compare the findings and determine the impact of using two methods in combination. The first outcome of the research was a synthesized framework of evaluation criteria that was applied in the two UEMs. Secondly, findings of the evaluations indicated that two UEMs identified similar problems, thus confirming their reliability in usability evaluation. Another finding was instances where one method produced results not obtained by the other, which shows the complementary value of two different UEMs. A third benefit of the study was that it identified usability problems in the target system. / Information Systems / MA (Information Systems)
