This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

An approach to teaching biology to mixed ability groups which primarily relies on individualized instruction is described. (BR)

Evaluated was the effectiveness of programed materials developed to present elementary college physics experiments in mechanics to non-science college majors. The group working with the materials were compared with a group receiving instruction in a conventional lecture-demonstration situation. No significant differences were detected between the…

Presents the procedures, results, and conclusions of a study designed to examine the differential effects of instruction, audio-tutorial mode and the teacher-directed group mode. Subjects were 60 third grade pupils using the Interaction Unit of the Science Curriculum Improvement Study. The effects of a combination of the two instructional modes…

The laboratory approach to science and mathematics is described as a refreshing change for both teacher and students. Suggestions are given for planning a laboratory-based program. Guidelines for teachers of both handicapped and non handicapped are included. A school for handicapped children in Minneapolis is described. (EB)

Describes an experiment using an analog computer which allows students to work with familiar problems, and to program the computers themselves. (SL)

Reviews the advantages of computer simulated environments for experiments, referring in particular to acid-base titrations. Includes pre-lab instructions and a sample computer printout of a student's use of an acid-base simulation. Ten references. (PR)

Discusses the use of self-directed learning in a large group class. Describes a workshop for developing group communication skills. (YP)

Explains the equipment and procedure necessary to conduct a successful field study of birds. Lists books, periodicals and recordings helpful in bird study and outlines a series of activities that students can conduct with birds. (GS)

The first of two brief articles describes the programming of a traditional English Physics course for the Sixth Form; the second describes the activities and specimens used in an introductory exhibition'' in Nuffield Combined Science at one school. (AL)
