Three experiments were conducted to examine the effects of providing extrinsic rewards for engaging in an activity on children's subsequent intrinsic interest in that activity. In each study, preschool children were asked to engage in an activity of initial intrinsic interest in individual experimental sessions. The children agreed to engage in…

Few concepts have ever raised simultaneously as many hopes and fears about the future of American education as has the idea of educational vouchers. Voucher proponents want to change the traditional system of using tax funds for financing public schools to an arrangement of providing tax vouchers to individual parents, who would purchase education…

This curriculum guide is the third in a series of general science guides modified from the New York State Experimental Syllabus, Science 7-8-9 to meet the needs of students whose interests are in areas other than science. The guide is laboratory-oriented and contains many open ended, pupil activities in five activity blocks: orientation, forces at…

This report explores the evolutionary process of the concepts of accountability and performance contracting from their inception through mid 1970-71. Six major topics are discussed: (1) ideological, managerial, and pedagogical underpinnings, (2) definitions and history of the concepts, (3) five performance contracting projects, (4) the political…

In two separate paired-associate learning experiments each employing 40 university students as subjects, the contribution of individual differences (IDs) in arousal to short- and long-term retention was investigated using IDs in salivary response to lemon juice stimulation as an index of arousal. Experimental subjects were pre-selected out of 184…

While science films can differ widely in their content and purpose, the making of such films rests on a pattern of principles, techniques, and matters of routine. This book traces that pattern and presents descriptions of how some particular problems were tackled previously. The history and state of the medium are overviewed, with information on…
