Autonomy: The importance of a scientific theory in education reform

The six national goals established by the National Governors' Association for education reform in the 1990s were conceived by people who had the power to decide what outcomes they wanted based on their own values and priorities. Although it is impossible to avoid questions of values, it is necessary in defining goals for education to consider scientific, explanatory theories about how human beings acquire knowledge and moral values. Jean Piaget's conceptualization of autonomy, in his unusual sense of the term, provides an overall aim for the development of individuals as well as of society, both in the intellectual and the moral realms. Autonomy as the aim of education is based on constructivism, a scientific theory, and would obviate the outdated conceptualization and contradictions among the six national goals.     

Differential costs of curricula in Illinois public junior colleges: Some implications for the future

The purpose of this study was to determine and analyze the annual cost of operation including depreciation of movable capital equipment for educating one student in each curriculum of selected community colleges and to show the relationship of costs of vocational-technical curricula to the cost for common baccalaureate oriented curricula.A stratified sample of eight community colleges was drawn from those that had been in operation for at least five years.These data indicate that a majority of the courses offered in highly specialized curricula in both the occupational and baccalaureate categories were more expansive than those courses that were common to a wide variety of curricula.This study supports differential program funding to assure continued development of high quality vocational-technical programs in community colleges.

Rates of responding in the pigeon generated by simple and complex schedules which provide the same rates of reinforcement

Four pigeons pecked for food reinforcement on variable interval 1-min schedules and on the variable-interval 1-min components of multiple, concurrent, and pseudoconcurrent schedules. The pseudoconcurrent schedule provided only one schedule of reinforcement; but, any reinforcer could be collected by responding on either of two keys. The rate of responding generated by the variable interval schedule was not greater than the rates of responding generated by the components of the complex schedules. But, the rate of reinforcement obtained from the variable interval schedule was greater than the rates of reinforcement obtained from the components of the multiple schedule. These results may contradict the equation proposed by Herrnstein (1970). The equation predicts that the rate of responding generated by a schedule of reinforcement will be greater when the schedule appears alone, than when it appears as one component of a complex schedule.     

In the dark II: spatial choice when access to extrinsic spatial cues is eliminated

Rats were tested in a specially constructed radial-arm maze that eliminated access to extramaze visual cues and allowed any effects of intramaze cues to be controlled. Despite this, choice accuracy was controlled by the spatial location of previously visited arms. Part of this control was attributed to vestibular or kinesthetic cues. This conclusion was corroborated by the finding that when explicit visual cues were moved from their standard (trained) spatial locations to novel locations, control of spatial choices was completely disrupted. The latter finding indicates that cues intrinsic to the rat (kinesthetic or vestibular information) and cues extrinsic to the rat (visual stimuli) operate in an integrated fashion.
