The primary objective of the current project was to convey authentic science to students in out-of-school student laboratories. High school students have diverse and partially wrong concepts of scientists' work. To convey more realistic concepts, we developed videos of scientists working on relevant and up to date scientific topics. These videos,…

This article aims to investigate how science teachers engaged with the macroscopic, sub-microscopic and symbolic levels of representations in their Chemistry teaching. Data were collected in Limpopo province in South Africa from 15 "lead" teachers and this paper reports on five lessons presented by the teachers during professional…

This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants…

Derived from basic language, VB (Visual Basic) is a programming language focused on the video interface component. With graphics and functional components implemented, the programmer is able to bring and use their components to achieve the desired application in a relatively short time. Language VB is a useful tool in physics teaching by creating…

This study evaluated the effects of a short-term professional development session. Forty volunteer high school biology teachers were randomly assigned to one of two professional development conditions: (a) developing deep content knowledge (i.e., control condition) or (b) evaluating student errors and understanding in writing samples (i.e.,…

According to many documents, there is a strong need to renew science education. One way could be to work with SSI (socio-scientific issues). This paper reports on both students' and teachers' experiences and learning when working with socio-scientific issues in science education in secondary school (aged from 13 to 16). The approach is…
