Abstract

This exploratory study examined the relationship between the knowledge of selected physics concepts from the South African National Senior Certificate curriculum and the self-efficacy beliefs of preservice science teachers. Forty-one preservice physical science teachers between the ages of 16 and 30 enrolled in a higher education institution to earn a Bachelor of Education degree made up the participants. Of these, 56.1% were female and 43.9% were male. Every respondent was a recent high school graduate from South Africa enrolled in a second-year university course on basic physical science. The preservice teachers completed the Science Teaching Efficacy Belief Instrument (STEBI-B) and a teaching confidence ranking scale. A confidence ranking for teaching topics from a typical high school science curriculum was determined by analyzing the data. According to the data analysis, preservice teachers are confident and self-sufficient enough to teach science concepts.

Abstract

Errors in solving quadratic equations are common among high school students and can significantly impact their mathematical proficiency. This study aimed to investigate the types of errors made by Grade 10 students and identify the factors contributing to these errors. The study was conducted in three senior secondary schools in Lebowakgomo District, Limpopo Province, involving ninety-nine Mathematics students, with nine selected for interviews. Data were analyzed quantitatively through students’ test scores and qualitatively using document analysis and interviews. The findings revealed that students’ difficulties were often reflected in errors related to carelessness, misapplication of numerical operations, order of operations, and challenges in handling algebraic equations. These conceptual and procedural inconsistencies hinder students' problem-solving abilities. The implication of this study is the urgent need for targeted instructional strategies that address conceptual understanding and procedural fluency to improve students' academic performance in Mathematics.

Abstract

This research examines the impact of pre-existing disparities on Grade 12 examination performance in Gauteng and the Western Cape Provinces of South Africa, utilising propensity score matching to balance influencing factors. The analysis focuses on learners from both provinces who participated in Grade 12 examinations from 2017 to 2019. Based on the 2017 datasets, it was found that learners in the Western Cape had significantly lower odds of passing compared to those in Gauteng when using unmatched datasets. However, after matching, the likelihood of passing for Western Cape learners improved to 69%, though they remained less likely to pass than their Gauteng counterparts. This trend was observed for the years 2018 and 2019. These findings emphasise the importance of using matched data to avoid misleading conclusions in comparative assessments of educational performance.
