Background: The Classroom Observation Project employs direct observations of geoscience teaching across the USA using the Reformed Teaching Observation Protocol (RTOP) to quantify the use of reformed teaching practices. We report on 345 RTOP observations used to evaluate the extent of teaching reform when curricular materials developed as part of…

Graduate teaching assistants (GTAs) play an essential role in the teaching of introductory chemistry courses at many higher education institutions. On the basis of best practices suggested by the literature, we developed our GTA training course to focus on modeling best practices in the classroom, providing opportunities for incoming GTAs to try…

The study investigated the relative effects of two activity-based instructional strategies on students' attitude towards Physics practical in secondary schools. The study adopted the quasi-experimental design of pretest, post-test and control group. The sample for the study comprised 74 Senior Secondary two (SS II) Physics students who were…

The study addressed the gap in fifth-grade science proficiency between English language learners (ELLs) enrolled in two different science programs in a large school district in the Southeast United States. The Inspire program was implemented in 125 schools, while a combination of Inspire and Promoting Science among English Language Learners…

This study investigates the effect of the science writing heuristic (SWH) approach on the quality of prospective science teachers' (PSTs) argumentative writing and their understanding of the components of argumentation in the SWH approach and their own learning. Ten SWH approach activities were implemented during the semester. The study was…

Recent policy reports and standards documents advocate for science teachers to adopt more student-centered instructional practices. Four secondary science teachers from one school district participated in a semester-long video club focused on honing attention to students' evidence-based reasoning and creating opportunities to make students'…

At universities where introductory physics labs are taught by graduate student teaching assistants (TAs), there is a need for specialized professional development for those TAs. This paper presents a specific instantiation of a model for lab TA professional development that uses a combination of cognitive apprenticeship and expectancy-value…

The purpose of this study was to explore the impact of an intervention on pre-service science teachers' self-efficacy to teach science through argumentation and explore the challenges they experienced while implementing argumentation. Forty pre-service science teachers in their final semester of schooling participated in an intervention that…

We describe the implementation of a graduate teaching assistant (GTA) training program in the Department of Chemistry designed to integrate with the professional development initiatives of the Graduate School at a large, public, research-intensive university. The program is a 1-year course of study that offers graduate students a chance to…

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…

The aim of this study is to determine the effect of activities developed in accordance with PDEODE teaching strategy on students' understanding of the particulate nature of matter. The sample of the study consists of the first grade students who study in the Primary School Teacher Education Program. In order to determine the conceptual change on…

This paper aims to gain insight into language production and academic language of 4- and 5-year-old students and their teachers in the course of a teacher intervention during kindergarten science education. The study is based on videotaped classroom observations, and specifically focuses on the academic language use of students (N[subscript…

For many years, changing beliefs has been considered a prerequisite for changing classroom practices. However, professional development research has also shown that the opposite relationship is also true--change in practice can precede change in beliefs. This study investigated the effect of a one-year professional development program on…

Students who struggle with vocabulary knowledge often see a decline in comprehension of content. Even students who receive strong reading instruction in the early elementary years may still experience the fourth-grade slump (Chall, 1983), which more often affects students from underserved populations. Many of those same students are also affected…

Background and purpose: To date, there has been little research on the Teacher Professional Development (TPD) for delivering a mobile technology-supported science curriculum. To address this, a TPD model for a science curriculum supported by mobile technology was developed and evaluated in this paper. The study reported focuses on the…
