Describing the processes that characterize children's thinking at successive stages of development, Jean Piaget's theories provide guidelines for the study of the intellectual development of children. These conference proceedings relate Piagetian theory to the helping professions. Through the use of panel discussion, symposia, test demonstrations,…

A group of 161 kindergarten and first grade children were instructed in mathematics using exercises in linear measurement to increase understanding of unit-quantity relations. A comparison group made up from two adjacent and comparable middle-class schools was taught mathematics without intervention into the mathematics content. Treatment and…

Studied were 48 retarded children, 9- to 18-years-old, (mental age 4 to 8 years) to determine effects of task screening and objectivity of protocol scoring on achievement of the concept of conservation. Results indicated no significant differences in achievement of conservation as a function of either experimental variable. Also data indicated…

According to the cognitive-congruency principle, humor appreciation peaks when the cognitive demands of the stimulus are congruent with the cognitive level of the child. This study tested the principle with jokes based on concepts associated with concrete operational thinking, conservation of mass and weight. This method provides a satisfactory…

Reported is a study to determine whether 249 ninth-grade students completing the third year of the Intermediate Science Curriculum Study (ISCS) instructional sequence performed differently on 19 conservation tasks than did 239 non-ISCS ninth-grade students. The tasks were presented via 35-mm color slides and a tape-recorded protocol. Students in…

The value of verbal rules given to learners as an instructional aid in forming desired concepts was investigated in this study. Two programs dealing with the concept of conservation of energy in heat exchange between liquids were prepared in the form of self-instructional booklets. One presentation used a picture-rule or expository treatment, and…

The study concerns the performances of first grade children in solving problems involving subtraction situations and the relationship of these performances to levels of conservation of numerousness and to I.Q. groups. The subjects were grouped into levels of conservation by a pretest administered prior to the main test of problem solving in…

A study was conducted to measure the degree to which groups of infants could generalize color across objects of different forms and sizes and generalize from across objects of different color and sizes and to see whether color or form would dominate in their generalizations. Ss were 8-13-month-old Caucasian infants. All tests had 16 Ss except the…

The purpose was to determine (1) if there was a significant difference in the performance on five science-related Piaget type tasks by fifth graders who were currently involved in different elementary science programs, and (2) if the tasks formed a hierarchical sequence of difficulty for the students. Three groups of fifth graders were studied;…

Twenty second- and third-grade children were tested on their ability to make judgements of certain area and volume equivalences. The children were then presented a conservation-of-liquid task. Of the 17 children who gave correct conservation responses, only two had solved the area and volume problems. Thus, contrary to what is suggested by…

The objective of this study was an attempt to clarify the nature of number conservation with number conservation tasks using variations in length, area, and volume. According to Piagetian theory, conservation is attained successively for number, length, area, and, finally, volume. It was hypothesized that success on the number conservation tasks…

This study examined the effects of a specified set of activities on the ability of educable mentally retarded (EMR) children to use the transitive property and conserve the three relations "same number as,""more than," and "fewer than." Thirteen EMR students, aged 12 to 15, were taught eleven lessons on establishing and conserving these relations,…

This report deals with the elements of a neighborhood conservation program which will require the formulation of criteria for selecting a project area, the testing of those criteria in a particular location, and the definition of specific tasks within the project area. The projects described are intended to provide the Michigan State Housing…

This publication was prepared as a guideline for citizens of Alabama who want to improve the environment of their state. This booklet includes 200 suggestions for improving the environment. These suggestions are divided into the following sections: (1) Our Ailing Air; (2) Our Ailing Earth; (3) Our Ailing Water; and (4) What Else You Can Do. The…

Presented is an outline of the program and abstracts of most presented papers for the 23rd National Conference of the Conservation Education Association held in August, 1976. The theme of the conference was Education's Role in Land Use Planning. Papers presented include a variety of topics related to land use, conservation education, natural…
