In this study, the role of science and computational thinking (CT) in teaching self-efficacy and design thinking variables were examined to explain the technological pedagogical content knowledge (TPACK) knowledge forms needed by science teachers for integrated Science, Technology, Engineering and Mathematics (STEM) within the framework of the…

Background: The importance of diagnostic and scaffolding activities for early science learning has been shown consistently. However, preschool teachers scarcely engage in them. We developed an instrument to assess preschool teachers' willingness to engage in diagnostic and scaffolding activities in science learning situations and examined its…

There is a collective agreement about the necessity of content knowledge (CK) as a prerequisite for pedagogical content knowledge (PCK). However, most PCK models lack explanatory power because of the missing link between CK and PCK. Thus, the study firstly attempts to develop a theoretical model that consists of knowledge of students' learning…

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…

This mixed-methods study investigated the relationships among preservice teachers' efficacy beliefs, pedagogical content knowledge (PCK) and their domain knowledge (DK) as related to mathematics and science teaching. Quantitative results revealed that participants' PCK was significantly correlated with their mathematics and science efficacy…

The aim of the current study is to analyze the relationship among teachers' TPACK levels, students' self-efficacy and the academic achievement. Another purpose of this study is to determine whether there is significant difference in teachers' TPACK levels according to their gender and professional experience. In this study, singular survey model…

Pre-service teachers need to acquire information and communications technology (ICT) competency in order to integrate ICT into their teaching practices. This research was conducted to investigate to what extent ICT-related variables--such as perceived ICT competence, perceived competence in ICT integration, attitudes toward ICT, anxiety around ICT…

This paper examines students' achievement and interest and the extent to which they are predicted by teacher knowledge and motivation. Student achievement and interest are both considered desirable outcomes of school instruction. Teacher pedagogical content knowledge has been identified a major predictor of student achievement in previous…

Background: Beginning teachers encounter several constraints with respect to scientific inquiry. Depending on their prior beliefs, knowledge and understanding, these constraints affect their teaching of inquiry. Purpose: To investigate quantitatively the longitudinal relationship between pre-service teachers' knowledge and attitudes on scientific…

Prior research has established that learning by teaching depends upon peer tutors' engagement in knowledge-building, in which tutors integrate their knowledge and generate new knowledge through reasoning. However, many tutors adopt a "knowledge-telling bias" defined by shallow summarizing of source materials and didactic lectures.…

Joellen Killion reports on the results of a five-year professional development intervention consisting of workshops and curriculum units conducted in six elementary schools in an urban district to gauge teacher knowledge and practices in science instruction for English language learners. The study looked at predictors of teacher change that…

The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers' teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers' beliefs about GM foods (content…

This study is a quantitative investigation of the relation of middle school science teachers' attitudes and beliefs about inquiry-based instruction to their accumulated amounts of science content preparation, content and pedagogical professional development, and their pedagogical content knowledge. Numerous researchers have found that even though…

What is effective teaching? It is not enough to say "I know it when I see it"--not when we are expecting so much more from students and teachers than in the past. To help teachers achieve greater success with their students we need new and better ways to identify and develop effective teaching. The Measures of Effective Teaching (MET)…

New K-12 science education standards emphasize teaching and learning grounded in authentic scientific practices. A first step toward supporting teachers' adoption of scientific practice-based pedagogies is to develop a clear picture of how teachers are currently teaching science, and what factors predict their pedagogical choices. A recently…
