Reports that a conference for professional chemists, educators in chemistry, and students was held to explore the issue of teaching chemistry to handicapped students. The ideas generated from the participants are intended to be used in preparing a manual of guidelines. (Author/SA)

Describes the use of undergraduate teaching assistants in electronic circuits and engineering management courses. Teaching assistants guide discussions and assist in laboratory exercises. Requirements for using teaching assistants effectively, benefits to teaching assistants, and possible problems are also discussed. (DS)

Discusses concept of covalent bonding as related to homonuclear diatomic molecules. Article draws attention to the existence of bound rare gas and alkaline earth diatomic molecules. Summarizes their molecular parameters and offers spectroscopic data. Strength and variation with distance of interatomic attractive forces is given. (Author/SA)

Discusses some problem areas as they presently exist in many secondary school laboratories in Australia, and presents some views on how safety in science should be presented to the Australian students. (Author/HM)

Instructions for making a simple respirometer, to measure rates of oxygen consumption of organisms, are presented. The instrument incorporates most of the basic elements of commercial respirometers but can be made inexpensively by high school students. Operating instructions and applications are given. (Author/SA)

This is an account of the discovery of a potentially dangerous high explosive chemical on storeroom shelves of secondary schools in Pennsylvania. A list of guidelines is given to eliminate problems in the future. (SA)

Models, based on Gowin's Epistomological V model, are presented which are intended to be useful in illustrating ideas to students about how knowledge is acquired and how to relate laboratory work to the concept being learned. (SA)

Details undergraduate physiology laboratory experiments that demonstrate mechanical properties of cardiac muscle, using strips from the ventricle of a rat heart. Includes procedures for obtaining length-tension curves, demonstrating the role of calcium in excitation-contraction coupling, and showing effects of several cardiovascular drugs…

Describes the development and implementation of an investigative laboratory class. The new laboratory design has been determined to be a success by faculty, teaching assistants, and students. Includes a sample laboratory description. (DKM)

Describes a repeat-measure study that provided data regarding learning styles based on social interaction and perceptions of a scientific collaboratory system from 40 university science students working face-to-face and remotely. Results showed students with strong competitive learning style preference had slightly more positive perceptions of the…

Presents an activity on chemical changes and experimentation with testing the roles of various reactants in accomplishing the changes. (Author/KHR)

Analyzes student performance on solution calorimetry problems in an introductory university chemistry class. Includes data from written classroom exams for 207 students and an extensive longitudinal interview with a student. Indicates learning difficulties, most of which appear to originate from failure to understand, that net increases and…

Introduces chemistry laboratories in which students have the opportunity to conduct laboratory projects in multiple sessions that promote planning, thinking, technical performance, and responsibility. Defines the process of experimentation and its applications to science laboratories and describes successful project applications. (YDS)

Describes a literature-based approach that was used successfully at the University of Cincinnati in a one-quarter advanced undergraduate inorganic chemistry laboratory course. (KHR)

Describes an inquiry-based teaching method implemented in an undergraduate exercise physiology laboratory course. Indicates students' strong, positive feelings about the inquiry-based teaching method and shows that inquiry-based learning results in a higher order of learning not typically observed in traditional style classes. This teaching method…
