Despite the importance of evolution to understand biology, there is significant evidence that many biology teachers have difficulties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers' pedagogical content knowledge for evolution (PCK[subscript evo]) was…

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…

Competence-based, science e-testing (CBSeT) is a novel external assessment tool which provides feedback to science teachers about their students' competence-based skills, thereby giving relevant assessment information which teachers could potentially use in their teaching practice. The aim of this study was to determine the extent to which…

This study reveals the transformation of prospective science teachers into knowledgeable individuals through classical, combination, and information theories. It distinguishes between knowledge and success, and between knowledge levels and success levels calculated each through three theories. The relation between the knowledge of prospective…

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…

The purpose of this study is twofold. Firstly, it attempts to determine the pre-service science teachers' misconceptions about floating and sinking. Secondly, it aims to reveal the level of pre-service science teachers' misconceptions, scientific knowledge, lack of knowledge, and lack of confidence related to floating and sinking. To conduct the…

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…

The purpose of the study was to investigate Junior High School science teachers' knowledge about contextualised science instruction. The study employed descriptive survey design to collect data. A test, Test of Science Teacher Knowledge of Contextualised Science Instruction was developed and administered to collect data on teachers' knowledge of…

It is a known fact that South African learners underachieve in mathematics. One possible factor that might have an influence on their mathematics achievement is the conceptual knowledge of mathematics teachers. In order to facilitate conceptual understanding, mathematics teachers themselves must possess profound mathematical knowledge. One key…

Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is…

Teacher knowledge of science content is an important but under-studied construct. A curricular and professional development intervention consisting of a fifth grade science curriculum, teacher workshops, and school site support was studied to determine its effect on teachers' science content knowledge as measured by a science knowledge test,…

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…

Science teachers' content knowledge is an important influence on student learning, highlighting an ongoing need for programs, and assessments of those programs, designed to support teacher learning of science. Valid and reliable assessments of teacher science knowledge are needed for direct measurement of this crucial variable. This paper…

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…
