A simple teaching model, designed to show rapidly which are the principal factors in population growth and how they are related, is presented. The apparatus described allows students to play several different active roles. (MP)

Compares an individualized audiotutorial (IAT) approach to teaching biology to ninth-grade students with the more commonly employed frontal classroom-laboratory (FCL) method. Indicates the IAT method was effective in increasing achievement and motivation in Israeli kibbutzim junior high school science students. (MP)

Steps to be used in the development of a comprehensive mathematics program for learning disabled children are outlined. While the suggestions given deal mainly with mathematics, it is felt that the identification of strengths in pupils can and should be part of planning in all curriculum areas. (MP)

It is noted there are few reported studies on programs that focus on parents and their middle-school children learning science together. Details of a zoo course are provided as well as data from a survey designed to find out what other courses could be taught in a similar manner. (MP)

Examines the impact of the aptitude treatment interaction (ATI) between cognitive style and study method on mathematical achievement of disadvantaged students. The findings are thought to suggest that individualized study methods should be investigated further as viable aids for disadvantaged elementary students. (MP)

Alternative techniques are suggested to some of the conventional approaches to teaching problem solving. Three general, conventional approaches are noted, and the nature and use of visual thinking is detailed as the fourth alternative. Examples of lessons with fifth graders using the fourth approach are provided to promote this method. (MP)

Details results of an 18-month project aimed at assessing the common practices, problems, and areas of difficulty faced by teachers and administrators in the instruction of elementary science. It is viewed as the most in-depth study in elementary science education ever undertaken in North Carolina. (MP)

A new instrument, the Animal Apprehension Scale (AAS), was tested with elementary education majors and inservice elementary teachers. It was indicated that females expressed more apprehension toward animals than males and that many animals have been "type cast." Twenty animals were chosen to make up the scale. (MP)

Suggestions are given for ways to help students sharpen their mathematical skills and clarify the value systems that underlie their present and future consumer decisions. Focuses on determining costs, solving household problems involving measurement, reading and interpreting graphs and tables, and using concepts of average and percent. (MP)

A recently developed and validated group assessment instrument, the Piagetian Logical Operations Test (PLOT), is described focusing on how teachers can use PLOT in improving learning in science classrooms. PLOT is an untimed 51-item instrument consisting of 13 content, 18 decision, and 20 reason items. (MP)

The needs of mathematics teachers who wish to provide relevance in their lessons, and the need to infuse energy topics into all disciplines in the curriculum at all grade levels, are addressed. It is felt children could be adversely impacted by present energy practice, and education is essential. (MP)

A 32-week program to improve earth science in-service preparation was instituted at Purdue University during 1978-1979. Results indicate that positive attitudes toward science and instruction were achieved. It is felt that programs can be successful in fostering positive attitudes and creativity only if they are 16 to 32 weeks long. (MP)

The relationship between content readability measures and mathematics test item difficulty was measured. An attempt was made to use readability to predict item difficulty. Results from the study are noted as somewhat discouraging, with only about 11 percent of the item difficulty variance explained by the selected readability measures. (MP)

Data from 79 physics teachers are analyzed to determine: (1) what were the inservice needs identified by at least 65 percent of this group; and (2) if physics teachers' inservice needs differ from science teachers in general. The top 13 needs appeared consistent with recent efforts to make physics more humanistic. (MP)

Thirty-eight classes--categorized as College Algebra, Mathematics for Elementary Teachers, and Applied Mathematics-- were selected at four state and six community colleges during the first semester of the 1976-77 school year. Results reinforced the notion there is actually no difference in ability due to sex. (MP)
