The editorial maintains that the perspective of hierarchical learning used in school science teaching should also be realized at college level science teaching. Perhaps the best teachers and intense attention should be devoted to the teaching of a introductory course where the concepts upon which further knowledge is based are learned. (PS)

Describes major theses of Piaget's work on development of intelligence. Implications of this work are significant in terms of methods, curriculum, and sequence of topics and activities used in science classrooms. Author cautions, however, that work of other child psychologists should not be completely forgotten because of Piaget's ideas. (PS)

The article presents numerical procedures for the validation and comparison of hierarchically organized curricula. Examples of specific hypotheses one should test, and calculations of five statistics for testing these hypotheses are given (consistency ratio, adequacy ratio, inverse consistency ratio, inverse adequacy ratio, and completeness…

English composition for the learning disabled child is discussed. Methods and sequence of the instructional principles are described. (CD)

Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…

Describes a study that attempted to establish whether or not a hierarchy exists among selected reading skills, to establish the direction and strength of such a relationship, and to compare empirical methodologies for establishing hierarchical relationships. (MKM)

The age of onset for tactual exploration of the fingers, body (torso), knee, foot, and penis by the fingers was determined in 100 normal infants. Journal availability: see EC 113 765. (Author)

Describes programed classroom instruction, indicating that it should be sequenced in small steps around complete concepts to elicit responses from students and provide immediate feedback. Notes that this instructional method involves students completely but requires more preparation time and training for the teacher. A sample of programed material…

A study involving 60 blind children (in grades k-2) was conducted to validate the hypothesized order of a series of tactual discrimination tasks and to determine the grade level(s) at which most "normal blind" children successfully perform simple tactual discrimination tasks presented on the Optacon.
