The application of principles learned in a first course in chemistry to chemical problems of interest to home economics majors specializing in clothing and textiles or fashion merchandising is described. Concept transfer--teaching difficult concepts in terms of an everyday analogue--is also explained and relevant laboratory experiments are…

Described are activities designed specifically for visually impaired students, demonstrating (1) meiosis, (2) mass, (3) enzyme-substrate reactions, (4) function and relationships of flowering parts. Employed are tactile and auditory learning aids, such as the tape recorder, electric eye, Braille typewriter, textured fabrics, and three-dimensional…

This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)

The use of the planetarium as a device for teaching elementary level deaf students is presented. The problems involving preparation of slides in English and in sign language are discussed. (SA)

Reviews a curriculum series entitled Examining Your Environment published by Holt, Rinehart and Winston of Canada, Ltd. Unit organizations, teacher's guides, activities, and materials are discussed. (SA)

Describes an undergraduate automatic controls course in which the teaching-learning process is regarded as a closed loop feedback system. The three basic components of the system: the controller, the plant, and the learning sensors are identified as the teacher, the student, and student feedback respectively. (SMB)

Some positive ways for educators to look at the decline in enrollment in Britian's secondary schools are presented. One large benefit at present appears to be that science teachers will be able to focus more attention on individual students and their needs. (SA)

A series of ten secondary-level, winter ecology experiences developed to accompany the BSCS Green Version is discussed. Results from a review by a panel of experts and ratings from experimental teachers are presented. (SA)

Tests and rejects the hypothesis that mixed-ability grouping enhances pupils' science achievement. Significant differences were found when 11 and 12 year olds (N=160) were compared. Mixed-ability groups using individualized methods performed at a lower level than did homogeneous ability groups. Also reports findings regarding teacher and student…

Tests Suggestology as an appropriate teaching-learning method for college juniors and seniors in an elementary science methods course. Results indicate higher levels of achievement in the Suggestology classes than in the traditional teaching-learning method classes. (CS)

Describes how to construct a game for elementary children who need to acquire skills in ordering or sequencing of items. Suggestions for its use in instruction are given. (SA)

Presents an evaluative study of the Nuffield A-level organic chemistry course which was conducted in the United Kingdom. Questionnaire surveys were used to compare the course content with the content Nuffield teachers and university lecturers thought should be included in an A-level course. (HM)

Outlines some recent developments in test-item analysis which are based upon a model of educational measurement developed by the Danish mathematician Georg Rasch. Illustrations of how science teachers in the United Kingdom can use the Rasch model are also included. (HM)

Presents the results of a survey study conducted in the United Kingdom to identify the opinions of 65 chemistry teachers from Middlesex and Buckinghamshire about the use, costs, design, and content of 0 level and A level chemistry books. (HM)

Describes an experiment, designed for use in the undergraduate laboratory, that measures the bond energies of molecules using a small commercial mass spectrometer and low-cost digital voltmeters. (BT)
