Graduate teaching assistants (TAs) are hired to assume some of the teaching duties in large general chemistry programs. They serve as liaisons between students enrolled in the course and the professor in charge. Being assigned to teach immediately on arrival at graduate school may be overwhelming to novice graduate students. When sending them into…

Active engagement in the classroom is one of the best tools available for overcoming conceptual difficulties. Science educators agree that students of all ages learn more by participating actively in the interpretation of scientific phenomena (NAS 2003; NSF 1998). In this article, the authors describe demonstrations in class using paper wads as an…

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis, which usually attacks the lung and is spread through the air from one person to another. Researchers from Johnson & Johnson Pharmaceutical Research and Development, the Swedish Institute for Infectious Disease Control and The Pitie-Salpetriere School of Medicine began their…

The undergraduate chemistry club of the Southwest Minnesota State University offers assistance in lead-testing through the anodic stripping voltammetry (ASV) technique to elementary and secondary schools. Emphasis is given to this community service activity, which has increased club membership, and promoted discussion of water quality problems in…

This article is a general summary of the James Flack Norris Award Lecture given in November 2003. It chronicles various events leading up to the award centering on teaching chemistry to very large classes and providing information to the general public through a unique University Office for Science and Society.

A survey of 1988-1992 doctoral graduates from 11 highly ranked chemistry departments found no statistical difference in the percentages of men and women who pursued tenure-track positions at Ph.D.-granting institutions. The goal of the survey was to determine whether the top National Research Council (NRC)-rated institutions were also the top…

A method designed to facilitate prediction of mechanism and products by developing critical thinking skills and reducing memorization is presented. The mechanistic disc method requiring students to utilize their understanding of charge stabilization, structural organic chemistry, and the fundamental mechanisms of aliphatic substitution and…

The purposes of this study were: to compare students' performance on conceptual and algorithmic chemistry problems; to investigate the relationships between learning orientation, formal reasoning, and mental capacity and students' performance on conceptual and algorithmic problems; and to investigate interactions among learning orientation, formal…

This contribution presents a tool elaborated from a theoretical framework linking epistemological, learning and didactical hypotheses. This framework lead to design teaching sequences from a socio-constructivist perspective, and is based on the role of models in physics or chemistry, and on the role of students' initial knowledge in learning…

This paper reports upon a study addressing teaching and learning about solubility to Turkish first-year secondary school students (age 14-15). The principal aim of the research was to investigate the impact on students' understanding of solubility, of introducing a simple particle model of matter. A teaching intervention to fit within the existing…

Even though philosophical themes in science education have been advocated for several decades, little attention has been paid to how these themes can be contextualized in the teaching of a particular domain of science. The purpose of this paper is to provide an example theoretical framework for applying a philosophical theme, reduction, in…

This study, based on constructivist learning theory, examined how effectively preservice chemistry teachers (N = 43) can be educated to think flexibly and to reorganize their thinking in a way that may complement diverse ways students approach the subject domain. The teacher's cognitive structure was assessed prior to and after a conceptual change…

In view of the research on education--and subject-related education in particular--that has been conducted in recent years, it would seem useful to describe the current state and future trends of research on science teaching and learning. In the present article, research findings are described, the deficits of science education are analyzed, and…

Many mathematics departments usually teach a variety of courses for students from different science departments and even from different faculties. These "service" courses are usually taught in the same way as the courses for mathematics major students. However, in science, because of the need to better analyse and interpret experimental…

The traditional order in which science courses are taught in U.S. high schools is biology, chemistry, physics. The physics course usually is regarded as very difficult because it requires both high-level mathematical skills and high-level thinking skills; it is taught in the final year of high school to provide time for students to develop the…
