Presents the mathematics of body size and surface area to volume. Examines arguments used related to the topic. Concludes that while some of the traditional arguments are valid, most are not. One analysis for an organism is provided in an appendix. (YP)

Described are the idea of chaos and the ability to control the chaotic behavior of a real-world physical system. Included is an explanation of the methodology and applications in biology and chemistry. (KR)

Describes an empirical study that was conducted to examine the relationship among scientific co-authorship (i.e., collaboration), research funding, and productivity. Bibliographic records from the MEDLINE database that used the subject heading for schistosomiasis are analyzed, global and local collaborators are discussed, and scientific…

Examines the conceptual development of high school students' understanding of scientific research over a school year. Results indicate that students' notions of scientific questioning are uniformed and they have little experience with data analysis or communication of results. Contains 18 references. (DDR)

Describes construction of citation network systems and some subsystems (time sequence network, cocitation network, couple network). Establishes structural modeling of these systems by means of system engineering. Explains and analyzes citation network systems. Includes graphs and charts. (JAK)

Describes a study of students' (n=106) written questions about topics they considered extremely interesting and not very interesting. Finds that there were significant positive relationships for questions written for high and low interest levels, and also significant positive relationships between question level and achievement in reading,…

Campbell and Skinner used an A-B design to evaluate the effects of the Timely Transitions Game (TTG) on room-to-room transitions in a sixth-grade classroom. The TTG incorporated explicit timing, publicly posted feedback, and an interdependent group contingency with randomly selected transitions and criteria. The purpose of the current study was to…

A unique behavioral paradigm has been developed for "Periplaneta americana" that assesses the timing and success of memory consolidation leading to long-term memory of visual-olfactory associations. The brains of trained and control animals, removed at the critical consolidation period, were screened by two-directional suppression subtractive…

This paper considers the unique and successful combination of using Direct Instruction programs with special education populations. The introduction establishes the need for valid, scientifically based materials. Next is a description of studies using Direct Instruction with students who have high-incidence disabilities. Thirty-seven studies were…

Most studies on feedback compare elaborated feedback types presenting knowledge on the correct response (KCR) immediately together with further information to simple feedback types providing knowledge of result (KR) or KCR. This study uses bug-related tutoring feedback (BRT-feedback) offering strategic information for error correction, but no…

It is hard and getting harder to strike a satisfying balance in teaching. Time dedicated to student-generated models or ideas is often sacrificed in an effort to "get through the syllabus." I describe a series of RNA interference (RNAi) experiments for undergraduate students that simultaneously explores fundamental concepts in gene regulation,…

This paper examines the relationship between industry and university research, focusing on developments in the United States from the 1950s through the 1980s. It found that while industry spent less than 2 percent of its research funds on academic research in 1965, it spent almost 5 percent on academic research in 1989. It also found that in the…

Problems exist in the use and application of information from scientific research in decision-making processes in education. On a macrosocial level, a theme is present in the use of information in decision making that is applicable to relationships between science and politics. This theme is strongly influenced by the prevailing national culture…

A study was done of the transfer of knowledge between academic and firm scientists. Beginning with theories of university and university scientist behavior and a theory of firm and firm scientist behavior, the research used a bibliometric analysis of articles prepared by firm-based scientists within the computer equipment and aircraft industries.…

This Office of Technology Assessment report on the current state of research and development in the telecommunications industry in the United States examines four specific areas of research as case studies: computer architecture, artificial intelligence, fiber optics, and software engineering. It discusses the structure and orientation of some…
