Developing students' understanding of and about science is an important educational goal. Learning the nature of science (NOS) has been recognized as a critical component of science literacy, affecting how students (our future citizens) make informed decisions. Textbooks can be useful teaching materials if the content presented aligns with…

Literature shows that science teachers' development and practice of PCK have always been a concern in science education research. Globally, national policies have begun to underscore the instruction of science teachers as a great concern. This study is considered worthwhile, as it intended to address this gap by exploring a beginner teacher's PCK…

The technological, pedagogical and content knowledge (TPACK) framework was developed incorporating content, pedagogical and technological knowledge. Studies used TPACK constructs and reported on teachers' TPACK and student learning, but none explored the correlation between teachers' TPACK and the achievement of their learners. This research…

This study explored teachers' experiences in the teaching of electricity and magnetism during a Lesson Study intervention. Using a case study research design, a sample of 4 physical sciences teachers was conveniently selected from schools in rural and suburban areas. Due to logistical challenges, the 4 participants were grouped into 2 separately…

It has recently been suggested that pedagogical content knowledge (PCK) has a concept-specific nature, beyond the topic-specific level of PCK. This paper reports a case study of three pre-service teachers' reported PCK about three fundamental concepts within the topic of electrostatics, namely electrostatic force, electric field and electric field…

In an exploratory study, 36 South African physical science teachers' understanding of basic concepts concerning electric and magnetic fields was studied from a perspective of possible concept confusion. Concept confusion is said to occur when features of one concept are incorrectly attributed to a different concept, in the case of this study to…

This article reports an exploratory multi-case study on how science teachers understand and envisage addressing learners' misconceptions about electric circuits. Four teachers from schools in and around a large South African city participated in the study. An open-ended questionnaire was designed in a novel way, questioning teachers about wrong…

The impact of computer simulations on the performance of 65 grade 11 learners in electromagnetism in a South African high school in the Mpumalanga province is investigated. Learners did not use the simulations individually, but teachers used them as an interactive demonstration tool. Basic concepts in electromagnetism are difficult to understand…

This study diagnosed the understanding about energy and biological-context energy concepts held by 90 first-year South African university biology students. In particular, students' explanations of energy in a biological context, how energy is involved in different biological situations and whether energy is present and what types of energy are…

This study focuses on the effects of the exposure of pre-service education students (n=87) to a variety of toys used as educative curriculum material in an attempt to develop their understanding of energy. Changes in their knowledge, their confidence in terms of this knowledge, and the reasons they attributed for any changes in both their…

This article considers the relationship between gender and self-efficacy in teacher trainees engaged in an electricity-related design and construction task. Quantitative data (examination scores, task assessment, and questionnaire) and qualitative data (interviews and written student reflections) were collected. There is a gender bias in student…

Written for students participating in the Close Up government studies program, a week-long field experience in Washington, D.C., the readings in this booklet may be incorporated into social studies units on government, political science, or current events. Following an introduction to members of the Reagan Administration and the Supreme Court and…
