Recently, theorists have raised concerns that pedagogical content knowledge (PCK) has become "a stale metaphor" that disregards diversity and equity, offers little to help teachers address students' misconceptions, and portrays knowledge as "in the head" versus in practice. We refute these notions using grounded theory to…

Organic chemistry students struggle with understanding the energetics of chemical reactions. Reaction coordinate diagrams are one tool that is widely used in organic chemistry classrooms to assist students with visualizing and explaining the energy changes that take place throughout a reaction. Thirty-six students enrolled in organic chemistry II…

As astronomers further develop an understanding of the fate of the Universe, it is essential to study students' ideas on the fate of the Universe so that instructors can communicate the field's current status more effectively. In this study, we examine undergraduate students' preinstruction ideas of the fate of the Universe in ten semester-long…

It is necessary to focus on environmental education at every stage of education in order to raise the awareness of the students about the environment and make the information permanent. Before setting priorities for educational policy and taking precautions, necessary studies relating the determining the views of the students should be performed.…

Much research has identified organic chemistry as an area of difficulty for learners. There is also much literature pertaining to the factors that contribute to learners' difficulties. This paper explores the intersections of teachers' and learners' perceptions of teaching and learning organic chemistry respectively. Understanding these nuances…

This study aimed to document pre-service elementary teachers' (PSTs'), who are going to teach K-5, ability to construct as well as evaluate justifications varied in terms of levels of sophistication. Additionally, this study aimed to investigate how PSTs' knowledge of content in which they were being asked to prove influenced their ability to…

This study investigated prospective elementary (PEMTs) and secondary (PSMTs) school mathematics teachers' statistical reasoning. The study began with the adaptation of the Statistical Reasoning Assessment (Garfield, 2003) test. Then, the test was administered to 82 PEMTs and 91 PSMTs in a metropolitan city of Turkey. Results showed that both…

Both scientists and policy-makers emphasize the importance of education for influencing pro-environmental behavior and minimizing the effects of climate change on biological and physical systems. Education has the potential to impact students' system knowledge--their understanding of the variables that affect the climate system--and action…

Introduction: This paper reports the findings of a study of risk management in public libraries. The focus of the research was to determine whether the libraries had a risk management and disaster plan for major disasters. Method: A qualitative study was done to investigate risk management and disaster recovery in public libraries in South…

Conceptual change requires learners to restructure parts of their conceptual knowledge base. Prior research has identified the fragmentation and the integration of knowledge as 2 important component processes of knowledge restructuring but remains unclear as to their relative importance and the time of their occurrence during development. Previous…

The nature of science is a prevalent theme across United States national science education standards and frameworks as well as other documents that guide formal and informal science education reform. To support teachers in engaging their students in authentic scientific practices and reformed teaching strategies, research experiences for teachers…

Using the symbolic interactionist perspective that meaning is constituted as individuals interact with one another, this study examined how group thinking during cooperative inquiry-based activity on chemical bonding theories shaped and influenced college students' understanding of the properties of ionic compounds in solution. The analysis…

Youth suicide is a serious public health issue in the United States. It is currently the third leading cause of death for youth aged 10 to 19. School-based prevention programs may be an effective method of educating youth and enhancing their help-seeking. Most school-based suicide prevention programs have not been rigorously evaluated for their…

In 2011, a small Midwestern school district referred an increasing number of 2nd-4th grade students, with reading problems due to phonetic and phonological awareness deficits, to the district's intervention team. Framed in Shulman's pedagogical content knowledge model and the International Dyslexia Association's phonological deficit theory of…

The paper focuses on analysing grade 12 learner errors and the misconceptions in calculus at a secondary school in Limpopo Province, South Africa. As part of the analysis the paper outlines the nature of mathematics errors and misconceptions. Coding of learners' errors was done through the lens of a typological framework. The analysis showed that…
