Describes and evaluates the effectiveness of some optical media enabling visually impaired students to become active learners in the science classroom. (SK)

Described is the secondary science teacher's answer to the needs of their limited English proficiency students. Topics include the parallels between acquiring a first and a second language, the kind of learning environment most conducive to language learning, and scientific processes which are used for instructing students with English as a second…

Discussed are incorrect uses of matriculation examinations. Suggestions are made for possible changes in the secondary school systems including several types of senior secondary schools for those not seeking employment after four years of schooling. Recommendations are made for ways of matriculation examination scores. (DS)

The authors provide criticisms of the teaching of organic chemistry in the United States. They suggest that changes be made in the method of presentation of the material, with topics introduced early in the course providing framework for subsequent material. (Author/SA)

Describes an introductory physics laboratory course, used at the University of California in Berkeley, designed to teach students some general intellectual skills. Results of the course evaluation are also discussed. (HM)

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)

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)
