Both failures and successes have been experienced in the application of the computer to the teaching of introductory chemistry at Simon Fraser University. Chemistry teachers looked to computer assisted instruction (CAI) to improve instruction because CAI effectively dealt with chemical concepts and their practical application and with the wide…

The major features of Computer Managed Instruction (CMI) are diagnosis and testing, analysis, record keeping, and prescription. Diagnosis and testing are used to evaluate each student's performance at regular intervals. The results are analyzed to update the student's record and provide a prescription which suggests the learning process the…

Papers presented at the University of Birmingham, England, focus on teaching of a second language for the explicit purpose of facilitating the study of scientific materials written in English, French, and German. Articles include: (1) "Alternatives to Daffodils," (2) "English in the Teaching of Science and Technology throughout the World," (3)…

Evaluating a 1975 summer science workshop designed to help upgrade science teaching skills among Bureau of Indian Affairs personnel (administrators, teachers, and education specialists), this report focuses upon program effectiveness and participant utilization of the training. Specifically, this report presents: (1) project objectives (to train…

This teacher's guide to Spanish language at the kindergarten level includes a recommended subject presentation sequence for the Spanish curriculum, a sample schedule, a grouping of students using three stations, and a classroom layout. The grouping would be effective when at least one-third of the children are Spanish-speaking or bilingual. The…

A study was conducted to test and compare the effects of a group-paced, multimedia, non-lecture method and a traditional lecture method of instruction in General Biology, and to determine if the type of evaluation used influenced a student's chances of successfully completing the course. Subjects were 308 students enrolling in General Biology…

Describes a laboratory exercise designed to introduce students to the Pourbaix diagram for cobalt. Discusses the use of a Pourbaix diagram as a potential-pH plot which displays some of the most thermodynamically stable species for a given element. Outlines a laboratory demonstration and a student investigation. (TW)

Outlines five simple and inexpensive methods for students to use in identifying unknown substances. Provides a table of general solubility data for ions, a suggested list of unknown substances that can be tested using the methods described, and some prelaboratory information. (TW)

Uses capillarity as an example of a problem in physics which has been explained mathematically in two different ways. Argues that only one explanation is indeed valid and demonstrates this opinion through experimentation and discussions. Proposes that mathematics should be used in physics as a tool to predict, not to explain. (TW)

Describes the reasoning patterns characteristic of the abstract thinking required for higher levels of school science. Discusses control and exclusion of variables, ratio and proportion, conservation involving models, compensation and equilibrium, correlation, probability, combinatorial thinking, coordination of frames of reference, and…

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Focuses on the development of a pilot unit for use in an advanced separations process laboratory in an effort to develop experiments on such processes as reverse osmosis, ultrafiltration, adsorption, and chromatography. Discusses reverse osmosis principles, the experimental system design, and some experimental studies. (TW)

Discusses the effects of fiber-optics and other new technologies on communication technology courses. Explores several of the technologies that are applicable to this type of course. Describes how various applications can be presented and highlighted using inexpensive classroom demonstrations. (TW)

Reports on a study to test the effectiveness of a cognitive motivational model of course selection patterns to explain the continued participation of men and women in college chemistry courses. Results indicated that a person's belief about their ability was the major factor in deciding to continue in chemistry. (Author/TW)

Provides the syllabus for an undergraduate course on "Technology and Society" offered at the University of Missouri (Kansas City). Includes a general description of the course goals, required media log, and student mini-projects. Contains the list of assigned readings and a weekly breakdown of topics and assignments. (TW)
