- Description: In this study toys were used as educative curriculum material in an intervention on the topic of energy aimed at Intermediate Phase pre-service science teachers (n= 87) registered for a BEd degree at the Nelson Mandela Metropolitan University, South Africa. The intervention consisted of, amongst other elements, lectures, assignments and toy workshops, with the latter being a key driver in the process. The choice of toys as the educative curriculum material was informed by the fact that there is a huge variety of simple, reasonably priced and easily procured toys that are suitable to demonstrate the concept of energy from both theoretical and practical perspectives. The conclusions that can be drawn from the study are that the use of toys in the preparation of pre-service primary school teachers has the potential to substantially improve their subject content knowledge (SCK), pedagogical content knowledge (PCK), and their confidence related to these two constructs with respect to their understandings of energy. The data generated also suggest that when appropriate educative curriculum materials are integrated into a topic in science-teacher education, there may be a substantial positive impact on pre-service teachers‘ confidence in both their understanding of the science content and their perceptions of their ability to teach this content. An additional finding of the study was that, despite its popularity, status and usefulness over many years, the Science Teacher Efficacy Belief Instrument (STEBI-B) shows low sensitivity to measuring changes in efficacy as a consequence of the so-called ‗ceiling effect‘. The ceiling effect is a result of initial high scores which provide little opportunity to show iii substantial positive change as a result of an appropriate intervention that is designed to improve efficacy. While this study did not directly address this lacuna in STEBI-B, it made use of an innovative descriptive statistic, ‗percentage gain of potential‘, in an attempt to describe and interpret even small changes in efficacy as measured by STEBI-B.

- Description: Many theories on the nature of science and the nature of learning have been proposed. In particular, two theoretical orientations have been identified as having a decisive impact on activities in the school science classroom, namely "Inductivism" and "Constructivism". Inductivism views observations as objective, facts as constants and knowledge as being obtained from a fixed external reality. The constructivist view sees all knowledge as "reality" reconstructed in the mind of the learner. Each view predisposes certain orientations towards the science curriculum and within it particularly to assessment. It is postulated that teachers' views on science will influence how they teach and assess it. An "inductivist" teacher is more likely to reward certain approved responses from learners whereas a "constructivist" teacher is more likely to attend to learners' unique observations as evidence of their thinking. In this study a questionnaire was developed in an attempt classify science teachers according to their views on the nature of science and learning, and during this process encourage them to reflect on these views. It is hoped that the instrument could measure any changes in teacher's views as a result of the teachers becoming more reflective practitioners over time. Research indicates that the majority of teachers have a predominantly inductivist view of science. The study confirmed the results of other researchers by showing that a majority of non-tertiary science educators could be classified as being strongly inductivist. However, the overall proportion of these teachers was not as high as expected. Of possible concern was the indication that the strongly constructivist group showed very strong inductivist tendencies when assessing written tests which involved pupils' responses to laboratory observations.
