This paper describes a student-centered approach to teaching and learning physics in a high school classroom. The teacher designs and uses a 5E learning cycle to teach series and parallel electric circuits. This article provides an example of the implementation of 5E model for a physics lesson to address three-dimensional learning-science and…

Educational researchers have been interested in studying teachers' professional identity to understand this dynamic and multifaceted construct within personal and professional processes through different experiences. In this study, we designed a qualitative case study with Cultural--Historical Activity Theory (CHAT) to examine physics teachers'…
