Recursion is an important concept for any computer science student to master. Many first year students develop the viable "copies" mental model of recursion and can successfully trace the execution of a simple recursive function. This article discusses a study focused on determining whether the ability to successfully trace a recursive…

Information Communication Technology (ICT) implementation in Namibian schools is still in its infancy in rural science classrooms at junior secondary school level. The research reported in this paper adapted the Four-in-Balance model that reflects the pillars of the use of ICT in classrooms. In order to explore the extent of the implementation in…

Project-based learning (PBL) is the recommended approach for teaching technology in South Africa. The implementation of this approach, however, is problematic since the vast majority of technology teachers are not formally trained in technology education. Consequently, many of these teachers rely on technology textbooks for guidance. Therefore,…

In this article I present a discussion of mathematics teacher educators' descriptions of their practice, in particular, how they see their role in promoting home languages as the language of learning and teaching in Malawi. I also explore how mathematics teacher educators prepare pre- service teachers to teach mathematics in home languages in…

Learning support materials, including commercially prepared textbooks, play a central role in the implementation of a new curriculum. In South Africa, classroom resource materials such as textbooks are reported to have had a considerable influence on Teachers' pedagogical practices. The aim of the article is to explore the criteria that Grade 9…

This study shows how worksheets can be used to support learning in an informal learning environment. Although there has been some research into the use of worksheets in museum settings in developed countries, it is still not clear whether worksheets enhance or inhibit learning. Using a case study of grade 4-7 learners visiting a biology exhibition…

This study focuses on the effects of the exposure of pre-service education students (n=87) to a variety of toys used as educative curriculum material in an attempt to develop their understanding of energy. Changes in their knowledge, their confidence in terms of this knowledge, and the reasons they attributed for any changes in both their…

This paper reflects on the difficulties students have in understanding, designing and constructing electrical circuits through an analysis of errors they have made in drawing wiring and circuit diagrams. Prior to wiring a model house, a sample of 114 primary school teacher trainees were taken through a programme of instruction in current…

The research reported in this paper investigates the impact of, and challenges with, encouraging argumentation on students' conceptual development in physics. It draws its theoretical framework from two socio-cultural perspectives of learning, i.e. that learning science occurs in a social setting and secondly that learning science is a discursive…

The international community looks towards Education for Sustainable Development (ESD) to address global problems such as environmental degradation, poverty and ill-health. This article focuses on the integration of ESD into science lessons. It reports Junior Secondary School (JSS) science Teachers' perceptions of the ESD concept; its integration…

Research has shown that affordances of computers may be exploited in the design of mathematical tasks so as to provide interesting and challenging activities. At the same time, opportunities for learning mathematics may be constrained if the design of the task is not appropriate. A tool which allows teachers, researchers and task designers to…

This study focuses on Grade 6 learners' perceptions of 'learning as design' during the creation of a collaborative hypermedia product. Data were generated via a Likert Scale questionnaire, semi-structured interviews, learner journals, observational notes, Task Elicitation List, Task Ranking List and open-ended learner evaluation reports. The…

This qualitative study document action research which explored existing teachers' views and practices during the implementation of professional development to strengthen learner centred teaching. The paper discusses changes in teachers' practice that culminated in the delivery of enhanced lessons. The paper documents a two year process of change…

The purpose of this qualitative case study involving six secondary school teachers was to obtain insight into how geometry is taught in selected Nigerian and South African high schools. It also aimed, by making use of the van Hiele model of geometry instruction, to elucidate what possible learning opportunities observed instructional methods could…

The purpose of the study was to assess the level of gender awareness of science teachers in Zimbabwe's two education districts. A semi-closed questionnaire was administered to a sample of 100 science teachers. The questionnaire assessed teachers' gender awareness based on content, teaching methods, classroom dynamics and their general perception…
