- Description: The Department of Basic Education (DBE) examiners’ diagnostic reports for 2012-2019 indicate that National Senior Certificate (NSC) learners mostly perform poorly in examination questions based on scientific investigations. The low performance by learners in these questions has been attributed to the failure by teachers to effectively mediate the learning of scientific concepts due to lack of science laboratories or poorly resourced laboratories in most rural schools. As a result, most learners are finding that scientific concepts are decontextualized and hence abstract. Thus, this study explored making use of Virtual Lab to mediate learning of scientific investigations using the topic Energy transformations. The study was located within an interpretive paradigm and a qualitative case study approach was employed. The study was conducted in four different rural schools in the Joe Gqabi district and seven Grade 11 Life Sciences teachers participated. Data was generated using semi-structured questionnaires, semi-structured interviews, lesson observation, workshop discussions, and journal reflections. The study was informed by Vygotsky’s (1978) Socio-Cultural Theory (SCT) as the theoretical framework, and Thompson and Mishra’s (2006) Technological Pedagogical Content Knowledge (TPACK) as the analytical framework. The results of this study showed that most educators have a positive predisposition towards the integration of Information and Communication Technologies (ICT) in their practice. The study found that using the Virtual Lab to teach Life Sciences has several benefits such as safe environment for conducting experiments; convenience and accessibility; positive teacher and learner attitudes and improvement on learner performance; elimination of physical limitations of a real lab; and availability top-class lab equipment and up-to-date reagents. The study also revealed some shortcomings that were associated with the use of the Virtual Lab. These are; lack of lab partner and peer-learning; and lack of direct supervision by a more knowledgeable facilitator. This study concluded that using the Virtual Lab enhances the quality of teaching scientific experiments in the selected under-resourced rural secondary schools. The study recommends the adoption of the Virtual Lab as a viable alternative to the conventional lab.

- Description: This study investigated the possible effects that the use of guided play using the 6 Brick Duplo Block approach might have in terms of the development of aspects of visual perception in pre-literate 5-7year old children. An explanatory sequential mixed-method design was employed. Seventy-seven Grade R learners in two schools, one in the Republic of South Africa and the other in the Republic of Kenya, comprised the purposive convenience sample. Quantitative pre- and post-intervention data were generated using the Visual Perception Aspects Test (VPAT) and analysed using Excel functions to generate descriptive and inferential statistics. The pre-test mean score in the Kenyan school was statistically and practically significantly lower than the South African pre-test mean score. This difference was attributed to the amount and type of play that took place in the natural settings of these schools prior to the intervention and the nature and amount of play material available in each. The largest improvements from the pre- to post-tests occurred in the South African and Kenyan experimental groups and the difference between them dropped from the 99% level of confidence in the pre-test to the 95% level of confidence in the post-test. These findings suggest that using the 6 Brick Duplo Block approach may accelerate the development of aspects of visual discrimination in pre-literate 5-7-year-old children and that the approach may be most effective when used with children who have had little previous exposure to guided play at school. Qualitative data were obtained through open-ended classroom observations and semi-structured teacher interviews with the experimental group class teachers. Classroom observation revealed that the learners were enthusiastic about the guided play and the semi-structured interviews revealed that they realise the importance of using guided play for developing the visual skills necessary for reading, writing and numeracy. The overall findings of this study suggest that the development of aspects of visual perception were accelerated in the study sample of pre-literate Grade R learners when their teachers facilitated guided play using the 6 Brick Duplo Block approach. Recommendations are made that curriculum developers, early childhood advisors and teachers should be made aware of the potential of using guided play and reconsider the Piaget‟s stages of cognitive development to design appropriate instructional materials that promote learners‟ visual perceptual growth and development.

- Description: This research report focuses on an investigation into the prevalence and nature of boredom in Grade 10 Mathematics classrooms in the Grahamstown region, South Africa. Boredom seems to be strongly evident in our classrooms. Quantitative data was derived from an initial survey questionnaire while semi-structured interviews were used to elicit qualitative data. The data from the survey was analysed quantitatively using descriptive statistics. The quantitative data was categorised according to the structure of the survey. The data was represented in bar graphs and then discussed accordingly. In the final narrative I infused extracts from the interviews with my quantitative analysis. The qualitative data was analysed and coded according to different categories and themes that emerged through repeated engagement with the interview transcripts. The findings revealed that boredom is a common problem in the 8 Grade 10 Mathematics schools in the Grahamstown region and this finding answered my first research question. To answer my second research question, the results showed that learners were bored due to many factors, such as; lack of understanding, repetition and the teacher’s actions and many more. My findings align with what is highlighted by Nett, Goetz, & Hall. (2011) that many learners from particularly the senior secondary schools frequently report episodes of boredom. The study recommends that teachers make their teaching more interesting, much use of concrete teaching materials and make mathematics tasks to be relevant and real.
