Enhancing conceptual teaching in organic chemistry through lesson study : a TSPCK-Based approach
(De Gruyter, 2025-04) Ndlovu, Bongani Prince; Nsele, Sphesihle Winile; Khoza, Hlologelo Climant
Conceptual teaching in science education and its implications for pedagogical research have been extensively studied. Likewise, lesson study (LS) has been recognized as a powerful tool for continuous professional development and effective teaching practices. Despite the recognized importance of LS and the affordances of topic-specific PCK (TSPCK) in developing conceptual teaching, the connection between these two approaches in fostering conceptual teaching, remains under-explored within science education. This study aims to explore the development of a conceptual teaching from the dynamic interplay of TSPCK components for teaching a section of organic reactions through a TSPCK-based LS. A qualitative research approach was followed with four teachers from Umkhanyakude district in KwaZulu-Natal. These teachers participated in a TSPCK-based LS to develop a conceptual teaching strategy using Content Representation (CoRe). The findings revealed that teachers progressed from a basic to a developing level of conceptual teaching expertise through LS, as measured by TSPCK component interaction. While the findings are not generalizable, they offer valuable insights into teacher development, highlighting LS as an effective approach for enhancing conceptual teaching in science. This study concludes by recommending large-scale research exploring the role of reflection and feedback during LS in developing conceptual teaching within TSPCK interventions.

Healthcare professionals' perspectives on interprofessional collaboration differ, although structured organisational environments and professional relationships remain essential for quality healthcare. We aimed to determine healthcare professionals' perspectives regarding interprofessional collaboration in tertiary hospitals in Gauteng, South Africa. Healthcare professionals older than 18 participated in this cross-sectional survey, conducted in Tshwane district. Snowball sampling recruited registered healthcare professionals who worked more than a week at the participating hospitals. A Google link with a consent form and questionnaire was shared with departmental heads to share with their co-workers; 77 people completed the questionnaires. All ethical principles were followed. Statistical Package for Social Science version-27 analysed data. A five-point Likert scale determined perspectives of healthcare professionals’ level of collaboration. A signed-rank test determined the significant difference between hospitals' personal and organisational factors. The participants perceived personal relationships among healthcare professionals as better than the organisational environment in interprofessional collaboration. The organisational environment requires improvement for better collaboration.
Evolving domestic tourism destination preferences post-apartheid
(Routledge, 2025) Struwig, Jare; Du Preez, Elizabeth Ann; elizabeth.dupreez@up.ac.za
Tourism is embedded within societal structures, and imbalances upheld through social structures, like systemic racism, leave symbolic boundaries where certain activities perceivably belong to designated population groups. Further, socio-economic factors impede travel behavior especially in emerging markets. Resultantly, marginalization becomes a barrier to inclusive tourism. Domestic tourism patterns in post-apartheid South Africa were explored to determine whether changes have occurred, and whether these changes are a function of race, ethnicity, or socio-economic status. Preferences for three different destinations were compared using two nationally representative samples from the 2006 and 2017 South African Social Attitude Survey. Results indicate that, although race and economic status remained significant, ethnicity was the main impacting variable and interactional effects between ethnicity, age, poverty status, and geotype explained most of the variance. While travel habitus and cultural distance influence preferences, the youth market within certain ethnic groups is most likely to transition to new tourism destinations.
