Luria's tapping test (tap once when E taps twice, tap twice when E taps once) was administered to 160 children (80 males, 80 females) between 31/2 to 7 years old. Older children were faster and more accurate than younger children, with most of the improvement occurring by the age of 6. All children tested demonstrated understanding of the instructions during the pretest, and most started out performing well, but younger subjects could not sustain this. Over the 16 trials, percentage of...

This document reviews studies of professional development for teachers to examine benefits to students in science and mathematics education. A major finding from this review was that programs that focused on teaching classroom management strategies or attaining knowledge of how students learn specific school subject matter provided later benefits to students. The more successful professional development programs were not simply courses in mathematics or science, but instead were about what...

The gender gap in schooling is puzzling given that the expected returns to an individual for increased schooling — as measured by proportional wage increments — does not differ by gender. This paper explores possible explanations for the disparity using a model of parental investment in children. The model allows for differences in investments due to differences in costs — including the opportunity cost of the child's labor as well as school fees and availability. Moreover, it indicates that...

In this paper we suggest using general system theory (GST) as a unifying theoretical framework for science and technology education for all. Five reasons are articulated: the multidisciplinary nature of systems theory, the ability to engage complexity, the capacity to describe system dynamics and change, the ability to represent the relationship between the micro-level and macro-level of analysis, and the ability to bring together the natural and human worlds. The historical origins of...

Much social and behavioral research involves hierarchical data structures. . . . Recent developments in the statistical theory of hierarchical linear models now afford an integrated set of methods for such applications. This introductory text explicates the theory and use of hierarchical linear models (HLM) through rich, illustrative examples and lucid explanations. The presentation remains reasonably nontechnical by focusing on three general research purposes—improved estimation of effects...

Discusses India's Special Orientation Programme for Primary School Teachers (SOPT), a new technology used to train large numbers of teachers so that the losses in transmission inherent in the "cascade model" are avoided. Responses from teachers and trainers show there is considerable potential for the exploitation of this technology. Contains 20 references. (VWC)

It is time to recognize that educational technology cannot be considered a panacea for educational reform. Technology, when properly used, can be a very effective tool for improving and enhancing instruction and learning experiences in the content areas. However, incorporation of electronic tools, such as computers and videodiscs, into classrooms must be accompanied by systemic change in the educational process. Successful utilization of technology depends on how we provide teachers with the...
