Understanding how the periodic table of elements is organized and how to read information from it is fundamental for understanding chemistry. Introductory chemistry courses usually include discussions detailing what elemental information can be determined by virtue of its position on the periodic table. Although many people have been exposed to…

A low-cost, low-tech colorimeter was constructed from a film canister. The student-constructed colorimeter was used to show the Beer-Lambert relationship between absorbance and concentration and to calculate the value of the molar absorptivity for permanganate at the wavelength emission maximum for an LED. Makes comparisons between this instrument…

Presents an example of a take-home discovery-based activity that supplements the lecture component of a general chemistry course. Involves the student in chemistry exploration outside the class. Extends the context of content and experimentation into a nontraditional laboratory environment. Reports that students find the challenges useful in…

Reports on a first-year laboratory sequence known as the Interdisciplinary Laboratory (ID Lab) introduced at Harvey Mudd College. The course seeks to illustrate commonality of investigative methods and laboratory techniques in biology, chemistry, and physics and introduce discipline-specific principles. Provides details of the experiments…

One of the goals of developing a new chemistry courses is to foster positive student attitudes toward chemistry and to capitalize on both positive and negative experience in helping students to see how teachers can influence students' interests in science with inquiry-based and discovery learning. Additionally the courses are conclusively helpful…

Defines an exploratory lab as consisting of a series of hands-on, qualitative activities that are safe, simple, and inexpensive, use readily available supplies, and illustrate a concept being studied concurrently in the course. Summarizes the results of four years of testing the exploratory program. (DDR)

Describes a course specifically designed to allay the fear of science in elementary teachers by teaching them science in a laboratory-activity setting. Provides valuable laboratory experience often lacking in general education science courses. Lists topics covered in guided discovery exercises. Contains 12 references. (JRH)

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

The task force of the American Chemical Society's Division on Chemical Education, which was formed to implement curricular change in chemical education, outlines recommendations that should be part of the curricular change process. The recommendations are divided into groups of areas altering course material and areas altering process goals of the…

Proposes that the psychological problem of students expecting a particular result in an organic chemistry laboratory and, therefore, working in an unthinking manner be attacked by assigning experiments that give students unexpected results. Gives four examples of such experiments with strategies for teaching them. (CW)

Advocates the use of discovery or guided inquiry experiments for developing critical thinking in problem solving. Provides a stepwise method for creating inquiry experiments and provides an example by comparing the two methods for a freezing point experiment. (JM)

Discusses the format of a semester course and provides details about grading, formative assessment, research papers, lecture activities, cooperative examinations, use of spreadsheets, and open-ended laboratory projects. Contains 15 references. (DDR)

Describes the application of the Piaget-based learning cycle technique for teaching an introductory organic chemistry course. Explains the step-by-step process used to convert a lecture course into a discussion-based active learning course. A learning cycle provides students with concrete material and aids them in understanding abstract concepts…

Describes implementation of the "process workshop" model for university chemistry classroom instruction. Defines process workshop as a classroom environment where students are actively engaged in learning a discipline and developing essential skills by working in self-managed teams on activities that involve guided discovery, critical thinking,…

Explains how the Mathcad computer program can promote the development of higher-order chemical thinking skills of students taking junior-level physical chemistry courses. The kinetics of first-order series and reversible reactions is used as an example of how this can be implemented within an interactive laboratory or lecture format. (PVD)
