Two separate subject matter areas, which were felt to represent two distinct types of learning situations, were selected for investigation, namely, a kind of logico-mathematical procedure--the transportation technique, and a visual form discrimination task--aircraft recognition. Two separate courses were developed for each subject matter area. One…

This paper is concerned with the question of relationship among preferred perceptual modes, selected independent variables which cause individual differences, and the resulting effects on conceptual behavior. Subjects ranged from four and one-half years to eight and one-half years of age. Each child chosen by the plan was screened for color…

The purpose of this study was to examine the relationship between the various techniques used to estimate the time required by the human to process a visual stimuli, i.e., recognize a stimulus input into the visual perceptual system. Sixteen tests of visual processing speed were administered to 110 undergraduate students. In summary, scores tended…

The reported research was designed to investigate the impact of learner control on performance and anxiety in a computer-assisted instruction (CAI) task. The first phase entailed the development of a two-hour CAI program on the identification of edible plants. The second phase was experimentation to determine the effectiveness of learner control.…

The primary purpose of this study was to identify and describe individual differences in teaching style (i.e., teachers' patterns of questioning and explaining) in a standardized teaching situation. The secondary purpose was to explore relationships between teaching behavior and other teacher characteristics: teaching experience; sex and selected…

The relative effects of chronological age, mental age, IQ or Piagetian task performance were investigated among 143 Ss of high, average, and low IQ. Two kinds of group comparisons were made on fifteen tasks: (1) groups of the same chronological age, but different mental age and IQ, and (2) groups of the same mental age, but different chronological…

This paper contains the argument that the major focus of social learning must be on the development of people who value a variety of cultural and subcultural life styles. Four major concerns confront the classroom teacher or curriculum developer: (1) valuing cultural diversity in the classroom, (2) organizing curriculum processes to encourage the…

In order to gather data bearing on the effects of individual differences of the "invariant stages" assumption of cognitive-developmental theory, 270 black, Chinese, and white subjects from 5th, 7th, and ninth grades were administered a new, 25-item, spatial reasoning task. It was predicted that age, ethnic group, and sex would…

This study compared various instructional practices and problems in open plan classrooms with practices and problems in conventional plan school buildings. One secondary and three elementary schools having open plan classrooms were each paired with a comparable school having conventional classrooms. Instruments were used to record: teaching…

Individual differences in general intelligence and in 8 different special aptitudes or skills were hypothesized to be independent of family size and birth order indices. Evidence to the contrary, in the form of linear correlations, was predicted to be due to the confounding influence of socio-economic factors. Among the more familiar demographic…

This report is a portion of a study of attachment behavior: behavior promoting contact and/or proximity of an infant to his mother figure. This report deals specifically with crying, response to brief everyday separations from the mother and to her return, and behavior relevant to physical contact with her. The subjects, 26 infant-mother pairs…

This monograph explores and develops the concept of nongraded schools and establishes a more precise definition for this concept. The first part of the monograph reveals the degrees to which nongrading has been bent and collapsed to accommodate grading, and interprets the values and data supporting the rationale presented for nongrading. The…

This study was undertaken to determine the progressive development in movement and movement patterns (coordinated movements of body parts used involuntarily to achieve an objective) of children 2- to 6-years-old, to identify general characteristics which may be studied for appraisal of growth and development, and to study variations in movement…

Two experiments were conducted to investigate the relationships between individual difference variables and discovery vs. non-discovery instructional treatments in learning of an imaginary science. All subjects were able to learn the material, but presentation of examples and rules (non-discovery) led to more rapid learning. There was no…

Research on which aspects of the instructional process are most appropriately placed under learner control is reviewed. The review covers representative experiments from the 1960's in brief and experiments at the University of Texas from 1970 to 1973 in more detail. Although it appears that learner control can be helpful in mainline…
