This Special Issue aims to present evidence about the relationships between content knowledge (CK), pedagogical knowledge (PK) and pedagogical content knowledge (PCK); the development of these types of knowledge in novice and experienced secondary science teachers; and how CK, PK and/or PCK impact students' learning. Since Shulman's introduction…

The "Dance Entry Level Teacher Assessment" (DELTA) measures pedagogical content knowledge and subject-specific content knowledge in dance. Created and administered jointly by the National Dance Education Organization and the State Education Agency Directors of Arts Education, DELTA represents a first step toward reaching national…

The Framework for K-12 Science Education and the Next Generation Science Standards (NGSS) underscore the importance of including engineering design process (EDP) within the science curriculum. The Framework and the NGSS raised engineering design to the level of scientific inquiry in an attempt to prepare a STEM-literate workforce for the 21st…

Pedagogical content knowledge (PCK) and content knowledge (CK) are important dimensions of teachers' professional knowledge that are addressed in education programs for science teachers. In this article we present the structure, content, and evaluation of a preservice biology teachers' training program (N=173) to develop an elaborate understanding…

Various inquiry approaches have been promoted in science classrooms as a way for students to engage in, and have a deeper understanding of scientific discourse. However, there is a paucity of empirical evidence to suggest how children's actions and engagement in these approaches, or "practical epistemologies" (Sandoval, Science Education…

In low- and middle-income countries, cascade models of teacher professional development are often used as routes to educational reform. In these models, external agents deliver professional development, which is then disseminated by in-country facilitators. However, little is known about how to support facilitators of professional development,…

Teachers' self-efficacy and engagement in classroom teaching play critical roles in making the integrated science, technology, engineering, and mathematics (STEM) education happen. However, the potential factors influencing teachers' self-efficacy and engagement in STEM teaching have yet to be examined. This study constructed a hypothesized model…

With increasing global requirements for the use of technological tools and resources in K-12 settings, there is a need to examine the technological pedagogical content knowledge (TPACK) levels of mathematics teachers because technology use in class may enhance students' engagement and motivation in learning mathematics. Hence, the purpose of this…

This research was carried out to investigate the effect of graphing calculator program supported problem solving instruction on mathematical achievement and attitude in transformation geometry subject. The study was carried out with 49 seventh grade students in a middle school in Balikesir province. A pre-test post-test quasi-experimental design…

Researchers and policy makers agree that all children can learn mathematics and that teachers play an important role in student learning. This phenomenological study interviewed 12 primary school teachers, providing insights into their experience and perspectives of mathematics education, highlighting the challenges and successes experienced by…

In this paper, we report on changes to teachers' knowledge and practices as a result of their participation in a professional learning initiative focused on cognitively challenging tasks and the pedagogies for enhancing student reasoning as such tasks unfold. Data from 239 primary teachers who responded to an online pre- and post-professional…

The purpose of this descriptive phenomenological study was to examine teachers' and students' perceptions of the impact of a semi-departmentalized classroom structure on mathematics teaching and learning in upper elementary grades. Participants were purposefully selected from teachers and students at the selected school, each completing at least…

Informal inference is a critical practice for students to engage in if they are to understand formal statistical methods. However, during informal inference students often utilize complex ideas that many in-service teachers are not prepared for as they have not had the opportunity to think deeply about statistics and develop statistical knowledge…

The study was aimed at determining the effectiveness of learning using Technological Pedagogical and Content Knowledge (TPACK) framework in helping the change of reasoning patterns and modes of Biology prospective teachers so that it facilitates in encompassing the Embryology as one of abstract concepts. The subjects used were 49 students of…

Learning model in Kazakhstani Universities is being focused on transforming education from teacher-centered to student-centered approach. This transformation requires academic staff retraining and a significant modernization of educational process. In this article we discuss issues of methodological readiness of academic staff for student-centered…
