Preservice Primary Teachers' Perceptions of STEM-Based Teaching in Natural Sciences and Technology Classrooms.

The teaching of natural sciences and technology in primary schools presents an opportunity to use innovative approaches to teach STEM-based activities. The subject presents opportunities for learners to experience STEM-based instructional approaches in their early school years; therefore, it is essential that preservice primary school teachers are adequately prepared for the task. This study explored the perceptions of preservice teachers of STEM-based teaching in natural sciences and technology classrooms. Using a qualitative research approach and a single case study of a science and technology teaching methods course at a South African university, five participants were purposively selected from a group of 42 preservice teachers who had participated in a project to develop lesson plans and reflect on how to teach STEM. The data collected were analysed using thematic content analysis techniques. The findings indicate that the preservice teachers used natural sciences as an entry point to teach STEM and underestimated the technology component. The preservice teachers had the perception that STEM is taught through activity-based strategies while incorporating assessment for learning. Although they identified activities that could be used to teach STEM, they did not link the activities with developing specific skills in the lesson plans. The study recommends that preservice teachers be taught to link STEM activities with the development of specific STEM skills.
