In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers' perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers…

Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

This study explores Ethiopian preservice primary science teachers' perception of mentoring practices. Using a survey design, the Amharic translation of Mentoring for Effective Primary Science Teaching (MEPST) was administered to 239 graduating preservice science teachers, enrolled in four teacher education colleges. In addition, we interviewed 20…

The purpose of this study was to understand how biology teachers experienced and learned from professional development (PD) in which the 5R Instructional Model was used as a framework for planning inclusive lesson for emerging multilingual learners (EML). The PD integrated biology content with the scientific practices of using mathematical…

We studied how the practices of modeling supported preservice teachers (PSTs) as a reflection tool for knowledge integration in their science methods courses. In this exploratory study, elementary (n = 4) and middle/secondary (n = 7) PSTs drew models of the process of teaching and learning, including what occurred before, during, and after…
