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…

An artificial, and generally unhelpful, divide between lecturers and students frequently occurs in higher education, especially among recent school-leavers. Bridging that divide allows lecturers and students to develop collaboratively to the benefit of both parties. Residential field courses provide an important forum to develop more mature…

This commentary talks about the worldwide health impact of lack of access to potable water. Household water treatment and storage (HWTS) is described as one approach to improving potable water accessibility in which students and educators can make a contribution to alleviate the problem of lack of access. The author suggests that, as chemists,…

This study describes an evaluation of the Peer-Led Team Learning (PLTL) reform model in first-semester general chemistry. PLTL was implemented in place of one-third of the available lecture time, maintaining the same amount of structured class time under the reform. The evaluation demonstrates that classes implementing the PLTL reform at the…

This article summarizes our experience at McGill University in developing a strong connection not only with a large number of students but also with the general public. This has led to the establishment of a cooperative team to deliver useful information about chemistry and science broadly via the radio, television, the Internet, lectures,…

Nature of science refers to the processes of scientific activity and the social and cultural premises involved in the creation of scientific knowledge. Having an informed view of nature of science is important in the development of scientifically literate citizens. However, students often come to the classroom with misconceptions about nature of…

A term-paper assignment that encompasses the full scientific method has been developed and implemented in an undergraduate science writing and communication course with no laboratory component. Students are required to develop their own hypotheses, design experiments to test their hypotheses, and collect empirical data as independent scientists in…

There has been much interest in magnetite (Fe[subscript 3]O[subscript 4]) due to its utility in adsorbing high concentrations of arsenic in contaminated water. The magnetic properties of the material allow for simple dispersion and removal from an aqueous system. An inquiry-based laboratory has been developed that illustrates these unique…

This study examined the representational competence of students as they solved problems dealing with the temperature-pressure relationship for ideal gases. Seven students enrolled in a first-semester general chemistry course and two advanced undergraduate science majors participated in the study. The written work and transcripts from videotaped…

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…

Successful completion of organic chemistry is a prerequisite for many graduate and professional programs in science, technology, engineering, and mathematics, yet the failure rate for this sequence of courses is notoriously high. To date, few studies have examined why some students succeed while others have difficulty in organic chemistry. This…

This study examined the effect of different anatomic representations on student learning in a human anatomy class studying the muscular system. Specifically, we examined the efficacy of using dissected cats (with and without handouts) compared with clay sculpting of human structures. Ten undergraduate laboratory sections were assigned to three…

Background: The need to evolve with our ever-changing student bodies has never been as great as it is today, particularly given the advanced technological aptitude of today's students. Purpose: This retrospective study evaluates student outcomes as they relate to overall course score and composite quiz and examination scores from a basic…

The Wii is a very popular gaming console. An important component of its appeal is the ease of use of its remote controller, popularly known as a Wiimote. This simple-looking but powerful device has a three-axis accelerometer and communicates with the console via Bluetooth protocol. We present two experiments that demonstrate the feasibility of…

Personalized, online homework was used to supplement textbook homework, quizzes, and exams for one section of a course in material and energy balances. The objective of this study was to test the hypothesis that students using personalized, online homework earned better grades in the course. The online homework system asks the same questions of…
