Penn, Mafor; Ramnarain, Umesh – Chemistry Education Research and Practice, 2019
This mixed method study investigated changes in 3rd year Bachelor of Education students' attitudes towards chemistry after learning interventions with virtual chemistry simulations. After participant students identified certain concepts from their 3rd year chemistry module as being abstract and not easily comprehensible, these concepts were…

Ramnarain, Umesh; Ramaila, Sam – Chemistry Education Research and Practice, 2018
This study investigated the self-efficacy of first-year Chemistry students at a South African university. The research involved a quantitative survey of 333 students using the College Chemistry Self-Efficacy Scale (CCSS) developed by Uzuntiryaki and Capa Aydin (2009). Descriptive statistics on data for the CCSS scales suggested that students have…

Veale, Clinton G. L.; Krause, Rui W. M.; Sewry, Joyce D. – Chemistry Education Research and Practice, 2018
Pharmaceutical chemistry, medicinal chemistry and the drug discovery process require experienced practitioners to employ reasoned speculation in generating creative ideas, which can be used to evolve promising molecules into drugs. The ever-evolving world of pharmaceutical chemistry requires university curricula that prepare graduates for their…

Nimmermark, Anders; Ohrstrom, Lars; Mårtensson, Jerker; Davidowitz, Bette – Chemistry Education Research and Practice, 2016
Almost 700 Swedish and South African students from the upper secondary school and first-term chemistry university level responded to our survey on concepts of chemical bonding. The national secondary school curricula and most common textbooks for both countries were also surveyed and compared for their content on chemical bonding. Notable…

Mathabathe, Kgadi C.; Potgieter, Marietjie – Chemistry Education Research and Practice, 2014
The ability to make realistic judgments of one's performance is a demonstration of the possession of strong metacognitive skills. In this study we investigate the relationship between accuracy of self-evaluation as an expression of metacognitive skill, and learning gain in stoichiometry. The context is an academic development programme at a South…

Siweya, Hlengani J.; Letsoalo, Peter – Chemistry Education Research and Practice, 2014
This study investigated whether formative assessment is a predictor of summative assessment in a university first-year chemistry class. The sample comprised a total of 1687 first-year chemistry students chosen from the 2011 and 2012 cohorts. Both simple and multiple linear regression (SLR and MLR) techniques were applied to perform the primary aim…

Ramnarain, Umesh; Joseph, Aleyamma – Chemistry Education Research and Practice, 2012
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…

Potgieter, Marietjie; Davidowitz, Bette – Chemistry Education Research and Practice, 2011
The development of the Chemistry Competence Test was prompted by the extensive curriculum changes in the South African school system after democracy was established in 1994. As chemists, we were concerned that there might be a lack of articulation between secondary and tertiary levels, since we anticipated that curriculum changes would have an…

Davidowitz, Bette; Rollnick, Marissa – Chemistry Education Research and Practice, 2011
Teaching organic chemistry at the undergraduate level has long been regarded as challenging and students are often alienated by the mass of detail which seems to characterise the subject. In this paper we investigate the practice of an accomplished lecturer by trying to capture and portray his pedagogical content knowledge, PCK, in order to reveal…

Potgieter, Marietjie; Ackermann, Mia; Fletcher, Lizelle – Chemistry Education Research and Practice, 2010
Early identification of students at risk of failing first-year chemistry allows timely intervention. Cognitive factors alone are insufficient predictors for success; however, non cognitive factors are usually difficult to measure. We have explored the use of demographic and performance variables, as well as the accuracy of self-evaluation as an…
