Developing teacher self-efficacy via a formal HIV/AIDS intervention

This study investigated the effects of a HIV/AIDS module on teachers' sense of self-efficacy regarding their ability to bring about behaviours in their learners which contribute to responsible living and a reduction of the spread of HIV in their communities. The sample was 128 in-service teachers studying in nine different centres in three South African provinces in their second year of a parttime degree in education. A modified Science Teaching Efficacy Belief Instrument (STEBI) was used to generate quantitative data, while semi-structured individual and focus group interviews provided qualitative data. Statistical analyses (ANOVA and MANOVA) revealed statistically significant differences between the participants pre- and post-test self-efficacy scores. Interview data suggested that improved confidence enabled the teachers to gain a better understanding of cultural barriers to HIV/AIDS education and the impediments to developing an effective HIV/AIDS policy in their schools. The study also highlighted the importance of leadership from school management for the successful adoption and implementation of an effective HIV/AIDS policy in schools. Enhanced confidence is noted as a motivating factor for teacher participation in community efforts to support those affected by HIV/AIDS.     

Simulation of Limb Frostbites in Air Medium

The clinical course of frostbites of the limbs was studied in 3 animal species (swine, dog, rabbit) with frostbites of different intensity and duration. Animals of different species exhibited different sensitivity of their limb tissues to cold. The rabbit proved to be the most adequate animal for frostbite simulation. Frostbites of similar area and depth of lesions can be induced by cooling according to different protocols.
