AN EXPERIMENT WAS CONDUCTED TO DETERMINE THE FUNCTIONAL RELATIONSHIPS BETWEEN SUCH VARIABLES AS TYPE OF MATERIAL, NUMBER OF RELEVANT ATTRIBUTES, AND PERFORMANCE OF A PERSON ATTAINING CONCEPTS. CONCEPT ATTAINMENT BOARDS OF THE BRUNER (1956) TYPE WERE USED, AND VARIOUS PARAMETERS CONTAINED IN THE BOARDS WERE MANIPULATED. THE NUMBER OF RELEVANT AND…

TWO METHODS OF RESPONSE DESCRIBED BY PIAGET AND INHELDER FOR DRAWING APPROPRIATE BOUNDARIES AND SELECTING APPROPRIATE PREDRAWN BOUNDARIES FOR HYPOTHETICALLY CUT, SOLID GEOMETRIC FIGURES WERE INVESTIGATED TO SEE WHETHER SECONDARY SCHOOL STUDENTS COULD RESPOND IN APPROPRIATELY TO THE MATHEMATICAL TASKS. THE RESPONSES OF 8TH-, 10TH-, AND 12TH-GRADE…

A SEQUENCE OF LEARNING TASKS WHICH USED NONVERBAL STIMULI TO INTRODUCE CONCEPTS OF VECTOR SPACES WAS CONSTRUCTED. THE SAMPLE WAS 20 CHILDREN FROM GRADES 5 AND 6 WHO WERE MATCHED ON THE BASES OF INTELLIGENCE, READING, AND ARITHMETIC ACHIEVEMENT. EACH STAGE OF THE PROGRAMED SEQUENCE WAS PRESENTED TO EACH SUBJECT AS A CONCEPT-FORMATION PROBLEM.…

This study examined the transition from concrete to formal operations in very bright children in an effort to determine whether high ability in concrete operations would carry over into formal operational ability, and also to investigate precocity in regard to formal operations. Subjects were 38 white middle-class children ranging in age from…

The relationships among the perception, representation, and construction of series are examined within a model of the acquisition of seriation abilities. The model is then related to two experiments with three-, four- and five-year-olds. The key feature of the model is the delineation of parallels among developmental changes in three arenas:…

This paper describes a series of studies which examine the early development of recall. Subjects were children about 2 1/2 and 5 years of age. Recall was tested on nine-item lists which were either composed of three objects from each of three conceptual categories or nine objects from nine different conceptual categories. Age differences were…

The article emphasizes the importance of the teacher listening to the student's questions and problems in math classes in order to understand exactly what the student is misunderstanding. (CD)

Describes laboratory activities which relate the mass, volume, density, and radii of atoms through the assumption that the smallest unit of matter is a cubic box containing one atom. From calculations based on macroscopic materials, the author feels that the concept of an atom may be better developed. (CP)

Demonstrations are presented in which children can be introduced to evidence of specific concepts enabling them to participate in such a way that any conceptual conflicts that might arise in this learning situation can be gradually reduced. (EB)

The development of the associative structure of physics concepts as a result of the content presented to the learner and the relationship between associative structure and academic achievement was investigated using a treatment and a control group. Assessment of associative structure may allow insight into a learner's progress which complements…

Discussed are "moves" in teaching mathematics that can serve as a basis for defining understanding. How to characterize and use moves is discussed, with specific examples and research evidence. (MP)

Describes the positive response to and the success of a course, called "Science in Action," that was offered to elementary school children on Saturdays, and took place in college laboratories of physical science and biology. (GA)

Based on the presumption that art teachers ought to be able to describe the value of what they do and place it within a framework for rationalizing the contributions of their work to the educational development of the students they teach, this research is an attempt to describe what children learn when they paint, draw, or make three-dimensional…

The community education concept is defined in terms of increased school-community relations and use of facilities, integrated k-12 curriculum, community involvement, programs and services for all age groups, and interagency coordination. The possibilities for community education centers and programs in rural areas are discussed in this article.…

Performance of over 200 third and fourth graders on a post test and a two-month follow-up measure showed that groups receiving lessons based on a task analysis instructional design performed significantly better than groups receiving placebo lessons at two levels of advanced mastery for the concepts, "equilateral triangle" and…
