Years of research on teacher quality indicate that the quality and effectiveness of teachers have a significant influence on learner achievements. The quality of teachers and their teaching practice is widely debated where quality may depend on the teacher having acquired sound and relevant knowledge and skills to ensure effective teaching. The…

Direct linkKritzinger, Angelique; Lemmens, Juan-Claude; Potgieter, Marietjie – International Journal of Science Education, 2021
Growing class sizes and the rapid advancement of information technology have prompted institutions to implement blended learning in their academic offering. There are few reports in the literature on a holistic assessment of the effectiveness of the instructional design of blended learning courses for large classes. We defined effectiveness from a…

Stott, Angela Elisabeth – Chemistry Education Research and Practice, 2023
The unit factor method, a generic strategy for solving any proportion-related problem, is known to be effective at reducing cognitive load through unit-cancellation providing step-by-step guidance. However, concerns have been raised that it can be applied mindlessly. This primarily quantitative prepost study investigates the efficacy of…

van Staden, S.; Graham, M. A.; Harvey, J. C. – Perspectives in Education, 2020
This study investigated the reading demands of restricted-use items administered to South African grade 9 learners as part of the Trends in International Mathematics and Science Study (TIMSS) 2015. The method proposed by Mullis, Martin and Foy (2013) was used to categorise items into low, medium and high readability groups. The 'knowing' domain…

James, Angela A.; Beni, Saritha; Stears, Michele – South African Journal of Childhood Education, 2019
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…

Van De Heyde, Valentino; Siebrits, André – Research in Science & Technological Education, 2019
Background: Students' well preparedness for laboratory sessions is of importance for a number of reasons including them being able to engage in and learn from the session and in acquiring the necessary laboratory skills needed for the scientific community and for possible further work in industry. To enhance the preparedness of the students an…

Stott, Angela Elisabeth – Chemistry Education Research and Practice, 2021
Stoichiometry calculation competence tends to be particularly poor in the developing world, even among teachers. Various methods, including the unit factor method, have the potential to be effective in developing such competence. To evaluate the likelihood of such a generic proportion method, which downplays traditional formula usage, succeeding…

Mnguni, Lindelani – Problems of Education in the 21st Century, 2019
Science is generally expected to respond to students and societal needs by adopting student and social accountability principles. Therefore, school science curricula are revised regularly to address emerging socio-economic, political, and scientific issues. Similarly, the National Curriculum and Assessment Policy Statement of South Africa was…

Sebatana, Motlhale Judicial; Dudu, Washington Takawira – Science Education International, 2022
The concept of self-directedness is a missing link in South African science classrooms, and as a result, science teachers are often not self-directed in employing innovative teaching and learning strategies such as blended problem-based learning (BPBL) that might enhance self-directed learning. The literature is replete with studies showing that…

Christine E. Mundy; Marietjie Potgieter; Michael K. Seery – Chemistry Education Research and Practice, 2024
General spectroscopy is known to be difficult for novice students due to its complex and abstract nature. In this study we used a first-year chemistry Mini Spec laboratory activity to uncover language barriers to student learning in spectroscopy. Analysis revealed that language barriers generated conceptual difficulties for English as Second…

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about…

Hencke, Juliane; Eck, Matthias; Sass, Justine; Hastedt, Dirk; Mejia-Rodriguez, Ana Maria – International Association for the Evaluation of Educational Achievement, 2022
Using IEA's Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief explores the relationship between students' gender, their confidence and achievement in mathematics and science, and their aspirations to pursue careers in these fields. We find that more boys than girls at grade 8 want to have a mathematics- or…
