Assessment of preparedness of first-year chemistry students: development and application of an instrument for diagnostic and placement purposes

Author: Potgieter, Marietjie ; Davidowitz, Bette ; Venter, Elsie Date: 2008 Many universities in South Africa use alternative admissions tests together with results of the Grade 12 examinations for access of placement. These tests focus on academic literacy and mathematical skills and do not provide information about ... Read more
Characterising learning in a demonstrator community serving first-year chemistry students at a South African university

Author: Wallace, P Karen Date: 2010 Teaching assistants (or demonstrators as they are called at South African universities) have become indispensable to the delivery of teaching particularly to first-year students, due mainly to the growing need in tertiary institutions to ... Read more
Development and validation of instruments to assess content knowledge and topic specific pedagogical content knowledge of teachers of organic chemistry

Author: Vokwana, Nonkanyiso Queen Date: 2013 In 1986, Shulman described Pedagogical Content Knowledge (PCK), as the transformation of Content Knowledge into various forms which help students to understand the concepts. In a later study, Shulman (1987) identified the construct of PCK ... Read more
Facilitating adjustment to higher education: towards enhancing academic functioning in an academic development programme

Author: Davidowitz, Bette ; Schreiber, Birgit Date: 2008 Several studies have emphasised the importance of addressing social and emotional factors in facilitating adjustment to tertiary education. This article describes the Skills for Success in Science programme at the University of Cape Town. The ... Read more
Grade 12 Achievement Rating Scales in the New National Senior Certificate as Indication of Preparedness for Tertiary Chemistry

Author: Potgieter, Marietjie ; Davidowitz, Bette Date: 2010 There has been much discussion on the impact of the new curricula for Grades 10–12 on the preparedness for tertiary studies of the 2009 cohort in subjects such as mathematics, chemistry and physics. Using the Chemical Competence Test that was ... Read more
Improving performance in a second year chemistry course: An evaluation of a tutorial scheme on the learning of chemistry

Author: Davidowitz, Bette ; Rollnick, Marissa Date: 2005 Throughput of students is a concern for academic departments especially since it will be the basis of a new funding formula for tertiary institutions. In order to reduce content for increased mastery, and ensure student engagement with chemical ... Read more
Increasing the signal to noise ratio in a chemistry laboratory. Improving a practical for academic development students

Author: Davidowitz, Bette ; Rollnick, Marissa ; Fakudze, Cynthia Date: 2003 In practical sessions students lack sufficient time or opportunity for deep processing of information. If the signal to noise ratio is too low, it can obscure the ‘chemical message’ which the lecturer is trying to convey. This study reports ... Read more
Preparedness for tertiary chemistry: issues of placement and performance of academic development programmes

Author: Davidowitz, Bette ; Potgieter, Marietjie ; Mathabatha, S. S. Date: 2008 The introduction of an outcomes-based curriculum in South Africa together with a new syllabus for physical sciences for grades 10-12, prompted the development of an instrument to monitor conceptual understanding in chemistry at the ...

Preparedness for tertiary chemistry: multiple applications of the chemistry competence test for diagnostic and prediction purposes

Author: Davidowitz, Bette ; Potgieter, Marietjie Date: 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 ... Read more
Reactivity studies of phosphoric amides and esters

Author: Davidowitz, Bette Date: 1984 The effect of protonation and Lewis acid-base interaction on the ¹H n.m.r. chemical shifts of the ester and amide bonds in selected phosphoramidates (RO)₂P(O)NR'₂ was investigated. The results are interpreted in terms of the interaction of ... Read more
Stakeholder perceptions of the efficacy of a capstone course introduced to assist accounting students in developing pervasive skills

Author: Maughan, Paul Date: 2016 A capstone course, Business Analysis and Governance (BAG), compulsory for all students studying towards becoming chartered accountants, was introduced at the University of Cape Town (UCT) in 2012. It was designed to develop pervasive skills ... Read more
Students learning-approach profiles in relation to their university experience and success

Author: Rollnick, Marissa ; Davidowitz, Bette ; Keane, Moyra ; Bapoo, Abdool ; Magadla, Lizo Date: 2008 What is the connection between student success and their approaches to learning? Do learning approaches develop with university experience? We explored these questions by constructing profiles using a specially developed fixed response ... Read more
Studies directed towards the synthesis of metal-containing ketones

Author: Davidowitz, Bette Date: 1977 The photochemistry of organometallic compounds is receiving increasing attention in the current literature, but as yet, little work has been reported on the photochemistry of metal-containing ketones. The objective of the work reported in ... Read more
Use of the Rasch measurement model to explore the relationship between content knowledge and topic-specific pedagogical content knowledge for organic chemistry

Author: Davidowitz, Bette ; Potgieter, Marietjie Date: Jun 2016 Research has shown that a high level of content knowledge (CK) is necessary but not sufficient to develop the special knowledge base of expert teachers known as pedagogical content knowledge (PCK). This study contributes towards research to ... Read more
What lies at the heart of good undergraduate teaching? A case study in organic chemistry

Author: Davidowitz, Bette ; Rollnick, Marissa Date: 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 ... Read more
