- Description: Each society on earth uses essential symbols which resemble the key ideas, attitudes and values that unite its members. Places are key symbols of many cultures around the world that shape the social, economic, religious, political and psychological aspects of a people’s world view. Its study, therefore, is of primary significance in the systematic reconstruction of a people’s cultural and spiritual experience and provides us with a reliable means of information about different subcultural zones of many a tradition. Oceans, mountains, forests, grasslands, deserts, lakes and rivers form the word’s generalized natural areas. Cameroon is one of the few countries in Africa that has been blessed with all the five broad symbolic places. It is this ecological endowment that must have influenced the authorities to refer to Cameroon as ‘Africa in miniature’. In other words, Cameroon is a microcosm of Africa. Since the life and spirit of Cameroonians are invariably affected by the contrasts in the ecosystems, we intend in this article to demonstrate how a place like mountains can provide an indispensable resonance of symbolization in the cultural evolution of Cameroonians and how the influence of a particular ecosystem like the mountain can be used to establish, consolidate and propagate cultural identity in Cameroon. We shall examine the symbology of each of the major ecosystems briefly before concentrating on that of the mountain.

- Description: This study aimed at investigating the conceptions and alternative conceptions regarding the optical phenomena ‘reflection’, ‘refraction’ and ‘total internal reflection’ amongst Grade 11 learners at a selected school in Mthatha, Eastern Cape, South Africa and developing remedies to enhance their conceptual understanding of this area. The study adopted a quasi-experimental pre-test – post-test design. To enhance the credibility of the findings of the study, the data were collected using mixed methods (both questionnaires and interviews). The questionnaires developed for the study were 4 tier Optics Diagnostic Instruments (4ODIs) which were designed in such a way that both qualitative and quantitative data could be collected. To explore the findings from the pre-tests, face-to-face interviews with selected learners from both the groups were conducted. This stage was followed by the design an optics teaching module which aimed at enhancing the experimental group learners’ conceptual understanding of the optical phenomena, whereas the comparison group was taught in the traditional teaching method. To test the effectiveness of the designed teaching module, the 4ODIs were administered as post-tests to both groups. To enhance the credibility of the findings from the post-tests, face-to-face interviews were conducted with some selected learners from the experimental group. Since the aim of the interviews at this stage was to test how the designed optics teaching module helped the experimental group learners in enhancing their conceptual understanding, the comparison group learners were not interviewed at this stage since they were taught in the traditional teaching method. The quantitative analyses were carried out using Microsoft Excel and the statistical software, IBM SPSS Version 20. The qualitative analysis was carried out manually by coding and categorizing the learners’ responses from the questionnaires and the interviews. The item analysis of the 1st tiers was carried out using Microsoft Excel. The statistical comparisons of the test scores of the 1st tiers of the tests (pre-test – post-test comparison of both the groups and the experimental group – comparison group comparison of both the pre-tests and the post-tests) were performed using t-tests (independent samples t-test and paired samples t-test). The 2nd tiers (learners’ confidence levels in their responses to the corresponding 1st tiers) and the 4th tiers (learners’ confidence levels in their responses to the corresponding 3rd tiers) were analysed by (using SPSS) calculating measures of central tendencies of their responses. The 3rd tiers (open-ended questions) and the interviews were analysed manually by coding and categorizing learners’ responses. Before the implementation of the optics teaching module, both the experimental and the comparison groups were found to hold a variety of alternative conceptions about the optical phenomena. Moreover, the performances of both the groups were the same. It was also found that the learners from both the groups were not confident when they approached the pre-tests. The qualitative analyses of the learners’ responses to the 3rd tiers and the interviews suggested that most of the correct responses given by the learners to tier-1 of the pre-test questionnaires originated from a faulty or vague understanding of the scientific concepts. Moreover, some of the incorrect responses identified could not be considered as alternative conceptions because of the very low confidence levels the learners displayed in these responses. Such responses were categorized as ‘errors due to lack of knowledge’. The analyses of the post-test questionnaires, and face-to-face interviews conducted immediately after the post-tests, revealed that the experimental group outperformed the comparison group in terms of their conceptual understanding of the optical phenomena. In other words, the number of experimental group learners who held scientifically-accepted concepts increased for some questions of the post-tests and in some other questions, the experimental group learners developed new scientific understanding of many situations with regard to the optical phenomena. To conclude, the findings of the study proved that the Grade 11 learners in the selected school held a variety of alternative conceptions and errors due to lack of knowledge. However, the optics teaching module, which was designed by taking into consideration the learners’ prior knowledge regarding the particular learning area, could remedy most of the alternative conceptions and errors which were merely due to lack of knowledge.

Peer-Assisted Learning Programme: Supporting Students in High-Risk Subjects at the Mechanical Engineering Department at Walter Sisulu University

- Description: The majority of the students who enroll at the Walter Sisulu University (WSU) in South Africa are not equipped with the necessary academic/learning skills to cope with the university environment, especially in Mechanical Engineering. The Department of Higher Education and Training (2013, p. 17), further states that “students’ support is crucial to ensure that students adapt to the demands of college life and that they can meet the demands of college programmes”. Particularly in South Africa, the school environment might also contribute to poor student performance as a result of insufficient student support, and a lack of facilities and resources. In order to address this gap, a Peer-Assisted Learning (PAL) programme was implemented to provide support targeting high-risk subjects for at-risk students in Mechanical Engineering at WSU. The programme therefore is pro-active and student-driven in that senior students assist junior students with their academic work and learning processes. The programme is designed to encourage collaborative and cooperative learning approaches during group sessions and active student engagement to support student learning (Laal & Laal, 2012). The programme requires substantial resources and time commitments. It is important from an operational, learning, and student perspective to understand in what ways the PAL programme assists students (if at all). Eliciting the experiences of students also helps the department to design interventions from a student-centred perspective using the lens of learning theories. This qualitative case study explores the student experience of the Peer-Assisted Learning (PAL) programme. Open-ended questionnaires/survey from 20 first-year students elicited their perceptions and experiences of the PAL programme. Responses were analysed thematically. Findings indicated that the students had useful insights that may contribute to revising the programme. Aspects mentioned were improved study skills, improved time management, and improved communication, problem-solving and presentation skills. The study suggests that the PAL programme also creates a safe (where students of the same age come together to discuss concepts of the subject under the guidance of the senior student as an experienced student), comfortable and conducive environment for first-year students’ learning. However, the gender dynamics within the programme point to revisions needed in the programme to address the gap on the gender balance as only six out of the twenty participants in this study were female. The study contributes to our understanding of aspects of PAL for first-year Mechanical Engineering students at WSU, as it affords students the opportunity to interpret, integrate and apply information/knowledge acquired during lectures and to interact effectively in small-group sessions.
