This paper reports a mapping of the astronomy content knowledge held by a sample of 171 Chilean in-service teachers, both from primary and secondary education, using a multiple-choice test. The responses were analysed by total achievement, and the proportion of alternative conceptions for each item was identified. Moreover, the test items were…

Teachers are increasingly expected to incorporate Project-based learning (PBL) pedagogy to teach science. While teachers' definitions and challenges in the use of PBL are widely studied, very few studies focus on the development of a teacher's knowledge of the use of PBL over multiple projects. The current research is an in-depth case study aimed…

The study assessed the science teaching confidence of preservice teachers in teaching elementary science by addressing two research questions: (1) Did preservice teachers understand the science concepts well enough to be effective in teaching elementary science content? (2) Did preservice teachers have the necessary science concepts and skills to…

An empirical investigation of elementary school teacher candidates on classification activities dealing with animate and inanimate objects in terms of being living or non-living demonstrates that as the size of the objects increases, subjects are more likely to classify them correctly as either being an animal or having living characteristics.…

The purpose of this report is to examine the performance of assessment items designed to measure elementary teachers' content knowledge for teaching (CKT) science as part of the ETS® Educator Series. The Elementary Education: CKT Science assessment is 1 component of licensure examination through the PRAXIS® assessments. The Elementary Education:…

This study investigated the differences between Taiwanese experienced and preservice elementary school science teachers' content knowledge (CK) about electric circuits and their ability to predict students' preconceptions about electric circuits as an indicator of their pedagogical content knowledge (PCK). An innovative web-based recruitment and…

This research summary accompanies the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in…

Systematic studies on the effectiveness of in-service teacher professional development (PD) are important for science education research and practice. Previous studies have mostly focused on certain outcomes of PD, for example, the effectiveness of PD for improving teachers' knowledge or students' learning outcomes. This study, however, explores…

Science learning environments should provide opportunities for students to make sense of and enhance their understanding of disciplinary concepts. Teachers can support students' sense-making by engaging and responding to their ideas through high-leverage instructional practices such as formative assessment (FA). However, past research has shown…

STEM education was a systematic teaching and/or learning process in the STEM fields and a positive correlation existed between STEM education, and the economic prosperity and power of a nation in the globalized world. In recent years, rising concerns have emerged about American STEM education. Many stakeholders wondered that whether the nation has…

Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the release of the Next Generation Science Standards (NGSS) in 2013. The new standards set off a chain reaction of standards adoption and…

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…

These appendices accompany the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the…

Since the beginning of the reform movement in science education, there has been concern that elementary teachers lack the science content knowledge (SCK) needed to engage students in authentic scientific inquiry. This study included 19 preservice elementary teachers and examined the development of their SCK within the context of a uniquely…

Pre-service science teachers' conceptual understanding of astronomical concepts and their misconceptions in these concepts is crucial to study since they will teach these subjects in middle schools after becoming teachers. This study aimed to explore both seventh-grade students' and the science teachers' understanding of astronomical concepts and…
