Teaching physical sciences in English as the Language of Learning and Teaching (LOLT) has presented numerous challenges, particularly for learners who are not proficient in the language. The South African government is increasingly considering the use of indigenous languages as the medium of instruction for subjects such as physical sciences,…

The importance of the enactment of formative assessment as a pedagogical tool in science teaching and learning cannot be over-emphasized. Teachers encounter pedagogical challenges when enacting formative assessment in science classrooms. These pedagogical challenges underscore the need to explore teachers' perspectives on pedagogical strategies…

With the introduction of the Life Sciences (LS) Curriculum Assessment Policy Statement (CAPS) in 2012 in South African schools, a practical examination has become compulsory in grades 10 and 11. The LS CAPS policy stipulates the types of practical work that needs to be conducted to develop specific process skills in learners. This interpretive…

South African teachers experience challenges with the implementation of the national school curriculum -- the "Curriculum and Assessment Policy Statement" (CAPS). In this regard, teachers may not feel empowered to effectively deal with the demands of the current educational policy. Concerns have been expressed about learners' poor…

In South Africa, where multilingualism is prevalent, codeswitching--a practice of alternating between languages--plays a significant role in shaping classroom dynamics and learning outcomes. This study explores the beliefs of both teachers and learners regarding code-switching in Life Sciences classrooms. Utilizing quantitative methods, the…

Redox reaction is an important concept in chemistry, and a well-organized knowledge structure of redox reaction is beneficial for concept learning. This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and…

Background: Although cutting-edge chemistry research can be an interesting and motivating context for students in pre-university education, few characteristics of supportive and effective learning materials based on such contexts are available. Purpose: In this study we investigated the design, implementation, and evaluation of context-based…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

This research is a needs analysis study aimed at developing a curriculum based on an interdisciplinary context-based learning approach within the 10th-grade physics course, focusing on the electricity and magnetism unit. The research was designed according to the case study model and data were collected from expert, teacher, and student sample…

This research aimed to explore the upper-secondary school chemistry teachers' and students' conceptual structures of atomic structure by using multidimensional scaling. Atomic structure is considered to be one of the most difficult concepts in upper-secondary school chemistry course so that the conceptual structure regarding atomic structure held…

This study assessed teachers' understanding about the nature of scientific inquiry (NOSI) and whether this understanding was reflected in their students' responses. The data were collected through the 'Views About Scientific Inquiry' (VASI) questionnaire, a reliable tool for assessing understanding about the NOSI. The sample included science…

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…

As COVID-19 accelerated through spring of 2020 the question became how will schools cope with protracted closure? Devising strategies to engage and educate students through full-time, online learning became a priority. At Tufts CSE we specialize in creating high school biomedical science curricula that foster engagement with science and build…

This study explores the perceptions of five in-service chemistry and mathematics teachers in using productive lesson study as a framework for teaching and learning. Introductory professional development workshops on horizontal articulation, productive pedagogy and lesson study were given to teachers at the onset of the project. Teachers were then…

Despite growing consensus regarding the value of inquiry-based teaching and learning, the implementation of such a pedagogical practice continues to be a challenge for many South African teachers, especially at rural schools. The research reported in this article concerns the interaction between Grade 10 Physical Sciences teachers' beliefs about…
