This qualitative case study involves a high school science teacher with a special education background in an urban school in the English School District of Newfoundland and Labrador. Conceptualized within the theoretical framework of Universal Design for Learning (UDL), this study examined the teacher's instructional practices and the tensions she…

Evolution is a difficult topic to teach; teachers admit not having enough knowledge of evolution and they face student opposition to learning evolution, especially based on religious grounds. Teachers are therefore motivated to gain knowledge in the field of evolution. We conducted a 30-hour evolution teacher training course, which included…

This study reports on eleven second-year teachers who were all students in the same practice-based secondary science methods courses framed around ambitious science teaching. In this qualitative embedded single case study, we examined if, how, and why novice teachers linked their current critical pedagogical discourses and instruction back to any…

The study investigated how explicit instruction of argumentation-in the context of socioscientific issues (SSI)- and explicit instruction of NOS, compared with explicit instruction of argumentation only, can develop grade 10 students' argumentation skills and NOS conceptions. Participants were 36 grade 10 students enrolled in two sections that…

Many high school classrooms in the United States have physics teachers who are teaching the subject outside their certified content areas because of a severe shortage of physics teachers. There is a critical need to improve the knowledge base of these out-of-field teachers. This comparative case study examined the instructional practice of…

Recent adoption of the Next Generation Science Standards (NGSS) across the United States has prompted teacher educators to reexamine effective strategies to improve science teaching practices that align with the principles of the NGSS. Past research attempted to address changing teaching practices by examining the alignment--or lack thereof--with…

The inclusion of engineering practices poses a challenge for many science teachers trying to meet the expectations of the Next Generation Science Standards because they lack formal training in engineering. This, however, may provide an opportunity for science teacher educators striving to improve the use of learner-centered teaching practices by…
