The ability to do inquiry does not necessarily translate to understandings about scientific inquiry or the processes by which scientific knowledge is generated. The study reported in this paper focuses on what students know about scientific inquiry and what impact school science may have on this knowledge. We investigated grade 12 physical and…

The advocacy for writing in science and STEM-related fields through reasoning-based writing, critical thinking and argumentation has been accentuated as a core competence in curriculum documents. In South Africa, the CAPS document for Physical Sciences acknowledged the importance of writing and consequently, call on teachers to engage in teaching…

Textbooks remain an important resource in the hands of science teachers in ensuring that curricular aims and educational reforms are realised in school science. In a publication of the National Research Council (NRC) entitled "A Framework for K-12 Science Education," emphasis is placed on students experiencing inquiry-based practices and…

The South African science curriculum advocates an inquiry-based approach to practical work. Inquiry is a complex and multifaceted activity involving both cognitive and physical activity; thus, paper-and-pencil items do not provide the authentic context for this assessment. This study investigates the construct validity of inquiry-related questions…

This paper reports on an analysis of student conceptions in responses to explanation-type questions in a grade 12 (17-18 years) South African national physics examination. We were guided in our analysis of 921 examination scripts by a framework developed by Dagher and Cossman on types of explanations in science which enabled us to understand the…

This study investigated the learning difficulties of grade 12 South African students in a national chemistry examination. A quantitative analysis of students' performance in the examination revealed there was a significant difference between student performance in questions where students needed to execute a transformation across levels of…
