This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

[This paper is part of the Focused Collection on Astronomy Education Research.] We examined teachers' spatial-scientific reasoning and the alternative conceptions they held regarding Earth-space content. While participating in a professional development (PD) workshop, teachers engaged in an integrated mathematics and science project-based unit…

This paper analyzed elementary teacher education (hereafter 'TED') programs in the top performing European (TIMSS) countries to help inform future elementary TED policy in the Kingdom of Saudi Arabia. Methodological emphasis revolved around how much emphasis should be placed on general content knowledge (GCK), as opposed to general pedagogical…

To identify links among professional development, teacher knowledge, practice, and student achievement, researchers have called for study designs that allow causal inferences and that examine relationships among features of interventions and multiple outcomes. In a randomized experiment implemented in six states with over 270 elementary teachers…

This paper reviews Ghana's performance in the TIMSS 2011 survey in comparison with other African and some high performing countries which participated in the TIMSS assessment. Students' achievement in the science content areas assessed were summarized and teacher preparation constructs of teachers of the students who took part in the assessment…

One chronic challenge facing professional development providers is the need to convene and support groups of role-alike K-12 teachers who require similar kinds of discipline-and grade-level-specific training. Online courses have become an increasingly common way to meet this challenge. This article reports on a randomized control trial that tested…

According to the National Research Council (NRC 2007), three critical components significantly influence students' science learning: teacher knowledge, teachers' opportunities to learn, and instructional systems. If students' science achievement is strongly correlated with teachers' science competence, and core competencies are central to…

Few elementary school teachers command a science background sufficient to offer children early and sustained opportunities to develop an understanding of science concepts, and facility with scientific modes of reasoning. This four-year, NSF-funded study was designed to investigate how and to what extent particular combinations of science content…

This article reports on issues arising from the external evaluation of a teacher development project--the Active Learning in Primary Science (ALPS) project--undertaken in eight Bristol (UK) primary schools during 2007. The ALPS project aimed to raise pupil attainment in science by developing participating teachers' skills, knowledge and enthusiasm…

This study has two parallel research agenda: (1) the development of social skills and pedagogical content knowledge in teacher candidates as they work collaboratively in pairs, and (2) the development of conceptual understanding and social skills in elementary school students who are taught by teacher candidates with cooperative learning…
