Covers use of cryogenic fluids, discussing physical properties, hazards to personnel, flammability, storage, transfer, and disposal. (JM)

Presents a series of tried and tested ideas for making the college and high school biology laboratory a place where students can become active investigators. Focuses on infusing investigative laboratories into existing courses, laboratory equipment, student capabilities, instructor time, and student and instructor attitudes toward laboratory…

Described is the status of science education reform in 1990. Different groups working on change, demographic trends in the US, student anecdotes, lab operations, the role of Sigma Xi, goals set by the state governors, industry efforts, and programs for the improvement of middle school teachers are discussed.

Reports on a naturalistic study conducted with 24 low-achieving high school biology students that determined how the teacher and students used two computer-based videodisk programs, a print-based activity, and a dissection laboratory to learn about frog anatomy and to conduct a frog dissection. Future research is suggested. (Contains 14…

This study documented the teaching practices of 2 exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Teaching practices are identified that may be considered exemplary and worthy of attention and analysis by other science teachers and science teacher educators. (PR)

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate),…

This study examined how, in some instances, participation in the cultural practices of high school science classrooms created intrapersonal conflict for ethnic minority students. Discourse analysis of videotaped science classroom activities, lectures, and laboratories was the primary methodology employed for analyzing students' discursive identity…

Because cell biology has rapidly increased in breadth and depth, instructors are challenged not only to provide undergraduate science students with a strong, up-to-date foundation of knowledge, but also to engage them in the scientific process. To these ends, revision of the Cell Biology Lab course at the University of Wisconsin-La Crosse was…

Student achievement, attitude, and instructional efficiency were determined for hands-on and for live and videotape demonstration laboratories for nonscience majors. Each of 3 laboratory sections experienced 3 different teaching methods for one 4-wk unit. No significant difference in achievement was found among the laboratory methods. An attitude…

Research suggests that undergraduate students learn more from lab experiences that involve longer-term projects. We have developed a one-semester laboratory sequence aimed at sophomore-level undergraduates. In designing this curriculum, we focused on several educational objectives: 1) giving students a feel for the scientific research process, 2)…

The third edition of this guide for teaching chemistry at all levels to students with disabilities covers classroom adaptations, testing and evaluation, computers in the classroom and laboratory, laboratory design, and laboratory safety. The needs of the growing population of students with learning disabilities are addressed, along with the needs…

An action research project was conducted to find ways of increasing the productive use of time in middle school applied technology laboratories. The population targeted for the study consisted of 26 middle school students in a growing middle-class Illinois community. The problem of nonproductive use of class time was documented through test…

This book presents 16 papers on problems and innovations in postsecondary engineering education. An introduction discusses the major issues currently facing engineering education. Chapter 2 briefly reviews the papers which are grouped under topics. Three of thee papers comment on teaching non-technical matters and attitudes. Two papers point out…

In response to a 1982 request by the U.S. Department of the Army, the National Research Council's Board on Army Science and Technology established the Committee on Army Manpower to investigate the professional environments and use of civilian and military scientists/engineers in Army laboratories. The committee's primary objective was to identify…

Canada is one of nearly 40 countries involved in the Second International Science Study (SISS). The Ontario Ministry of Education used the data generated in the study as a vehicle for assessing science education in the province, and comparing the province to the rest of Canada. Each chapter of this report contains a non-technical summary of…
