This dissertation study uses an alternative dissertation format to deliver two separate but interrelated studies. As a whole, the dissertation is connected by a single overarching research question: "What are the characteristics of effective, meaningful, and equitable science instruction through modeling and how do teachers' pedagogical…

Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

The purpose of the study is to investigate how pre-service elementary teachers' orientation about science inquiry impacts their implementation of inquiry-based instruction. Teaching orientation is one of the levels of pedagogical content knowledge (PCK) which impacts on teachers' instructional practice. With thirty-one pre-service teachers, data…

Background/Context: The emphasis on scientific practices articulated by the National Research Council framework and the Next Generation Science Standards requires significant pedagogical shifts for U.S. science teachers. Purpose/Objective/Research Question/Focus of Study: This study provides a rare window into the challenges and opportunities…

Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

The purpose of the study reported on here was to investigate the role of partnerships in helping in-service teachers overcome the difficulties associated with performing practical work prescribed in the Life Sciences Curriculum and Assessment Policy Statement (CAPS), an educational policy intended to transform the South African school curriculum…

This paper reports an empirical study of teacher development in the process of implementing an integrated science curriculum in a junior high school in China. Six science teachers with different subject backgrounds were invited to participate in this study. A pragmatic model of teacher learning that includes both cognitive and situated-learning…

Research on science-education reform affirms the importance of taking into consideration teachers' pedagogical beliefs in relation to the constructivist perspective to ensure successful implementation of a reform-oriented curriculum. In addition, prominent studies pinpoint the need for teachers to have sufficient pedagogical content knowledge…

Secondary school teachers in Tanzania have been attempting to implement the inquiry-based science curriculum since 2005. This study is descriptive and was designed within the realms of a Type IV case-study design (Yin, R. K. 2014. "Case study research: Design and methods" 5th ed. SAGE) to investigate their concerns in dealing with this…

Curriculum initiatives with intercultural educative aims are not uncommon in many schools around the world. This paper argues that these initiatives and their classroom implementation by teachers is strongly impacted and influenced by the prevailing neoliberal context of schooling. The findings of a project working with teachers on implementing…

Background: Foundation phase teachers are not science specialists; however, they are expected to teach science. It is important that research determines where teachers face challenges in teaching science in order to assist them to bridge the gaps and to improve their competence in teaching science. Aim: The aim of this research was to explore…

Background: Professional learning communities are increasingly recognized for their significance in building teachers' competencies for educational reform. However, the knowledge development cycle of technological pedagogical content knowledge (TPACK) through multiple professional learning communities is not well researched. Purpose: This…

This study explored the implementation of Project Lead The Way (PLTW) integrated science, technology, engineering, and mathematics (STEM) curriculum in four first grade classrooms. Data was collected from four teachers and two media specialists via interviews and student PLTW Light and Sound unit assessment scores. A self-efficacy survey was…

Designing professional development that effectively supports teachers in learning new and often challenging practices remains a dilemma for teacher educators. Within the context of current reform efforts in science education, such as the "Next Generation Science Standards," teacher educators are faced with managing the dilemma of how to…

This study explores foundation phase teachers' understanding of the natural science curriculum within the life skills learning programme. The theoretical framework for this study is entrenched in the relationship between the intended and the implemented curriculum. The Zone of Feasible Innovation (ZFI) is the proposed theory of implementation and…
