The National Center for Science Teaching and Learning (NCSTL) located at The Ohio State University conducts research on factors that while influencing the teaching and learning of science are generally outside teacher control. This NCSTL digest deals with the professional status and responsibility of science teachers in schools. While giving…

A unit of study for gifted fourth and fifth graders is described on the subject of mathematical periodicity and chaos and the underlying physical processes which produce these phenomena. Hands-on activities, data analysis tools and computer aids are used for instruction in simple periodic motion (pendulum), complex superposition of motions…

Provides a brief introduction to ways functional grammatical concepts can be used to understand the distinctive literacy demands of school science and history texts. Distinguishes this grammar from that of everyday language; examines the characteristic grammatical and discourse forms of content area learning; and discusses developing functional…

Using the problem of trash disposal as an example, students participate in science activities designed to develop the following science skills: classifying, observing, measuring, communicating, inferring, and predicting. Activities are described in detail and a reproducible page is provided. (JL)

Discusses two of the major research trends that are broadening the understanding of fluvial processes and changing the approach to investigations of stream behavior. These trends include research on rivers that do not flow in alluvial channels and detailed field studies on the mechanics of fluvial processes. (JN)

Discusses the role and value of scaffolding student discussions in advancing students' ability to coconstruct theories and models from data they have collected while investigating floating and sinking. (Author/CCM)

In this article, we examine the role that different participant structures can play in supporting inquiry-based science learning. We frame mastering scientific inquiry as mastering the "what," "why," and "how" of the cultural tools that scientists employ. We present a participant structure we call the teacher as partner and show how it renders the…

Reported are the results of a study involving 838 students (ages 5-15) from Australia, Great Britain, Sweden, Canada, and the United States to determine their knowledge, via a structured interview, about the aging process; parents; sex differences and preferences; birth, conception, and gestation; sex education; and clothes and nakedness.

Presents research results on photosynthetic, carbon monoxide utilizing bacteria. Discusses applications of the research and offers three sets of experimental procedures and data that students analyze to determine which bacterium from a soil sample uses carbon monoxide fastest. (Contains 21 references.) (MDH)

Describes personal experiences of a participant in the National Science Foundation program, Teachers Experiencing Antarctica. Uses the study of the temperature history of Taylor Dome to provide teachers with the experience of research and help other teachers recognize that there are opportunities outside the classroom for personal and professional…

Discusses the sociohistorical approach to tools and change. Explores the possibilities of computer-supported cooperative work. Discusses formative experiments on the educational environment as research opportunities. Illustrates the organizational impact of school technology by describing a project intended to create an environment for…

Poses some questions and practical answers to help teachers and students use computers effectively in science classes. Sample questions include: Does the increased use of computers in classrooms inhibit any student's progress toward scientific literacy? How do males and females respond differently to computer use in science classrooms? and How can…

This study examined the extent to which minority individuals with baccalaureate origins as non-traditional students (baccalaureates completed at age 25 or over) completed doctoral degrees in science and engineering. It compared the efficacy of their degree completion, i.e., elapsed time and registered time to degree, with that of counterparts with…

This report provides an analysis of issues and recommendations for further implementation of the National Education Goals and the America 2000 National Education Strategy related to education in mathematics, science, engineering, and technology. This report considers teachers and teaching at every level. The report focuses on the need to build a…

The increasing use of microcomputers and hand-held calculators has implications for mathematics and science instruction, achievement testing, and educational research. The potential effects of these technologies on curricula involve both content and delivery. In mathematics instruction, the focus may shift from manipulative to higher order skills.…
