This study investigated the extent to which the proposed Factory of Ideas (FOI) teaching approach impacted on students' understanding of energy based on their prior knowledge. The FOI is a didactic approach that, unlike the classic cognitive conflict approach, employs a variety of activities to offer students a scientific conception for comparison…

The derivative is a central concept in calculus and has applications in many disciplines. This study explored students' understanding of derivatives with a particular focus on the graphical (geometric) representation. The participants were four Mathematics Honours students from a university in Lesotho. Data were generated from the written…

This study explores the nature of classroom talk as a way of teaching physics implemented by newly trained teachers. Their training introduced them, among others, to sociocultural theory and the promotion of classroom talk as a deliberate teaching strategy. This study is framed by Mortimer and Scott's framework for productive classroom talk. Data…

Teacher-centred strategies have dominated most physics lessons in Lesotho. This study attempted to understand the contributing factors for the choice of teacher-centred teaching instead of learner-centred teaching with the goal of informing a professional development programme designed to address this problem. The paper responds to the research…

African traditional healers (THs) were interviewed in order to explore their indigenous knowledge (IK) concerning natural science topics and science teaching, with potential implications for school science curriculum. First, THs in Lesotho were interviewed about their general ideas and these were compared with ideas obtained from THs in a previous…

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…

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…

This paper analyses discourse produced in a larger study aimed at encouraging students in Lesotho to talk the language of science as a meaningful way of learning. The paper presents a semiotic and activity based analysis of discourses of students learning to talk physics while enrolled in a pre-tertiary access programme. Prior to the access…
