Describes a first-year laboratory course designed to fulfill laboratory objectives of reinforcing lecture material, teaching experimental methodology, developing hands-on skills, and imparting a sense of error. The course's six segments examine: digital electronics with students building a photogate timer; error analysis; linear accelerated…

Presents a unit of three lessons to teach Newton's Laws of Motion. After rotating through learning centers, answering questions, and recording observations, students are asked to generate a "class law" that explains the scientific phenomenon they observed. (MDH)

The Don River watershed is located within Canada's most highly urbanized area--metropolitan Toronto. Many residential and commercial uses, including alterations to the river's course with bridges, have had a significant impact on the Don's fauna and flora. Pollutants have degraded the river's water quality, a situation exacerbated by the…

Phonological awareness is thought to become increasingly analytic during early childhood. This study examines whether the proposed developmental sequence (syllable[right arrow]onset-rime[right arrow]phoneme) varies according to the characteristics of a child's native language. Experiment 1 compares the phonological segmentation skills of English…

A major challenge in teaching the process of science to students is designing and implementing laboratory activities that emulate what is actually done in a research laboratory. To facilitate this effort, science educators have been encouraged to design exercises that span multiple laboratory periods, encourage independent thinking, promote…

The research reported here focuses on links between teachers' comprehension of the underlying physics and their development of educational strategies for classroom work during in-service training. It deals with the teaching of hydrostatics, a topic considered particularly interesting by teachers. Starting from the analysis of simple experiments…

This study applied self-efficacy theory to assess empowerment to advocate on behalf of tobacco control policies. The Youth Tobacco Survey with added policy advocacy self-efficacy, attitudes, and outcome expectations scales was given to 9,177 high school students in Texas. Asians showed the lowest prevalence of experimentation and current smoking,…

This book brings together leading experts to offer an in-depth examination of how computer technology can play an invaluable part in educational efforts through its unique capacities to support the development of students' understanding of difficult concepts. Focusing on three broad themes-the nature of understanding, the potential of technology…

For several years at the Rural and Small Schools Conference, a special effort has been made to address the needs that are unique to rural science educators. This publication is a compilation of materials presented at those conferences reflecting the following themes: "In Search of Excellence" (1985); "Rural Education: A Proud…

To provide practice in making design decisions, collecting and analyzing data, and writing and documenting results, a professor of statistics has his graduate students in statistics and research methodology classes design and perform an experiment on the effects of fertilizers on the growth of radishes. This project has been required of students…

This packet contains four science learning activities on the subject of animal science that can be used in agricultural education courses. The activities cover these topics: (1) identifying internal parasites in domestic livestock; (2) the effect of feed preparation on feed palatability and consumption; (3) determining the absorption abilities of…

The curriculum materials contained in this document were developed through a cooperative effort by educators in the state of Maryland. It was a curriculum project aimed at the meaningful integration of mathematics and science. It is suggested that these materials be used in two significant ways. First, this document can serve as an instructional…

This document was compiled to help keep science and mathematics teachers in Australia abreast of the results of important research endeavors in education. The monograph is divided into 12 chapters. Chapter one, "Exemplary Science and Mathematics Teachers," (Barry Fraser and Kenneth Tobin) describes a study focusing on examples of…

This paper examines a research paradigm that is particularly suited to experimentation-related computer-based instruction and integrated learning systems. The main assumption of the model is that one of the most powerful capabilities of computer-based instruction, and specifically of integrated learning systems, is the capacity to adapt…

Minimal class participation by students with limited English proficiency (LEP), and LEP student failure to pass regular classroom tests were addressed through cooperative learning in a second grade science class. Classroom techniques used included strategies for using the scientific method of investigation, hands-on activities, experiments, music,…
