- Description: The current study investigated the determinants of Internet services’ adoption and use among high school learners in the East London Education District, in the Eastern Cape. Underpinned by the Unified Theory of Acceptance and Use of Technology, the research questions included: (1) What is the effect of performance expectancy on the learner’s intention to adopt and use Internet services? (2) What degree of variation exists for effort expectancy on the learner’s intention to adopt and use Internet services? (3) How much of the determinants explain the usage of Internet services? (4) Which is (are) the best predictor(s) of Internet service usage given a set of determinants? (5) What is the effect of confounding variables (if any) on Internet services’ adoption and usage? (6) Which model can be designed based on the best predictor(s) of Internet services’ adoption and usage for secondary school learners? A quantitative approach based on the positivist paradigm was used to quantify the relationships among various factors that contribute to Internet services’ adoption and use. The research design used was a survey. Data were collected through structured questionnaires. Out of 286 questionnaires issued, the response rate was 40.6%. The study sample size was 116 high school learners using simple random sampling. The data was analysed using the multiple regression analysis technique, and Pearson correlations. Out of the four determinants from the UTAUT, performance expectancy was the strongest predictor of intention to adopt Internet services. Large positive correlations ranging from r = 0.638 up to r = 0.989 were found among performance expectancy and effort expectancy variables towards the intention to use Internet services, significant at p < 0.05. To enhance the efficiency of the UTAUT model, this study has designed the Adoption and Application of Technology for Learning (AATL) model, which added the price of Internet, persistent use of Internet, and perceptions about Internet use.

- Description: The present study investigates the National Curriculum Statement (NCS) Mathematics curriculum Design issues which have a bearing on underachievement at Grade 12 in selected schools in the King Williamstown Education District. It stems from the premise that curriculum design is plausible explanation for Mathematics achievement. In pursuit of this line of thought, the study looked at curriculum design types such as linear, sequential, and spiral arrangement of contents, as well as curriculum design aspects such as sequencing, progression, integration, pacing and organisation of contents. The study also looked at the perceptions educators and subject advisors have with respect to the bearing that these aspects have on underachievement in Mathematics. The interpretive paradigm was used to frame and focus the study. The sample included five schools selected on purpose, with underperformance in Mathematics as an inclusion criterion. These schools constituted the cases of this research. Data was obtained from the interviews which were conducted with the Mathematics educators of the selected schools, and the Mathematics subject advisor of the district to find out about their perceptions with regard to the impact of Mathematics curriculum design on students’ underachievement in Grade 12. In addition, the contents of the National Curriculum Statement for Mathematics documents were analysed. The findings revealed that the scope (contents coverage) is too wide, and that the skills which are supposed to be developed in learners per term are not fully developed. Time allocation is unreasonably limited as a result learners are unable to cover the scope for the term. Revisiting of topics done every year in a spiral fashion is good but the balance between superficiality and depth is not achieved, and that it is done without checking and understanding learners’ previous knowledge on the topic. The sequencing of certain topics has to be looked into and revised. The study also revealed that Mathematics curriculum design, link and progression from primary to high school is good but not all details covered which leave students with content gaps that impede the learning of certain topics. The researcher came out with the following recommendations: From this case study, it appears that teachers still need more empowerment in NCS. Educators still need training on the NCS so they can be confident with the Mathematics NCS content. In most schools the scope is not covered and skills that are supposed to be developed in learners every term are not developed because of slow learners and the time factor. Therefore, the Department of education needs to give the scope taking into consideration the slow learners and make sure that the time they give every term also takes into consideration the time used for tests. It also appears that the learners are slow because of the language barrier. Educators spend a lot of time saying the same things to the learners so that they can understand. Since the learners do almost all the subjects in English and write their examination in English if they are from an English medium school, it would be a good idea for the DOE to introduce English to the learners as early as grade R, as in the model C schools. If that is done, it might remove the language barrier and hence reduce underachievement in Mathematics. It appears that the educators revisit topics every year but do not balance superficiality and depth. Educators should be encouraged to take every topic seriously every year and not just repeat what they covered in the previous grade. They should use it as a base for the new content. If that is done, it might help the achievement in Mathematics.
