Presents two examples of laboratory exercises using the World Wide Web for first-year medical students. The first example introduces the physical laws that apply to osmotic, chemical, and electrical gradients and a simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module…

The relationship between high stakes testing and the teaching of science was studied through case studies of two school districts and interviews and observation with 80 teachers and with principals, students, and district personnel in grades 8, 10, and 12 in British Columbia (Canada). Examinations discouraged teaching that promoted inquiry and…

Field experiences in a teacher certification program for elementary science, math, and technology were evaluated for their effectiveness in improving participants' cognitive, affective, and psychomotor ability. Surveys and interviews indicated participants felt little connection between the content coursework and educational methods course. They…

A study found first-year physics students at the University of Namibia (UNAM), considered to be a select group of students, to be as prepared for laboratory work as Australian tenth-graders. Comparison with students of Potchefstroom University (South Africa) found UNAM students deficient in both cognitive and affective aspects of laboratory work.…

Describes a project in which students exchange research and information about renewable energy. Describes exchange visits including conferences and field trips to relevant places of interest. Reveals that great Britain lags behind Germany in the use of renewable resources. (DDR)

Describes a unit that applies constructivist teaching methods to a science concept. Contains mini-lessons in math that present to students information that they need to know in order to perform their experiments. Gives students the opportunity to construct their own knowledge about the natural phenomenon of light as they apply their mathematical…

A grade 6/7 teacher and a teacher educator-researcher team-taught science to 29 students by framing science projects as adventure. Ethnographic data revealed that small-group instruction, whole-class discussions, and presentations to outside audiences provided progressive opportunities for students to exchange ideas and motivated students and…

A study of eighth grade science students compared the instructional effectiveness and the cost effectiveness of an interactive video system with the use of 16mm films for teaching a science unit. Results indicated that interactive video can be significantly more effective than conventional methods of instruction. (eight references) (LRW)

Described are the camps, competitions, and tests of the U.S. National Chemistry Olympiad. International competition, local exams, participating high schools, and national exams are highlighted. A summary of test results from the 1988 national examinations are presented. (CW)

Presented are reviews of two computer software packages for Apple II computers; "Organic Spectroscopy," and "Videodisc Display Program" for use with "The Periodic Table Videodisc." A sample spectrograph from "Organic Spectroscopy" is included. (CW)

Discusses a microcomputer-based laboratory (MBL) study (n=75) which uses multiple temperature gathering devices (mercury thermometer, digital thermometer, and computer probe) and graphing methods (hand graphs, delayed computer graphs, and real-time graphs). Reports that MBL real-time graphing provides significant increases in graphing skills. (MVL)

Discusses changes in chemistry education from 1983 to 1988. Describes the past and present situation of chemistry education. Reports on current teacher education programs. (MVL)

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Discusses the use of local networks and integrated learning systems in delivering instruction. Presents a summary of projects initiated by the states of Maryland, Florida, Michigan, Minnesota, and North Carolina. Notes that although network software is gaining popularity, most software is still for the individual user. (MVL)

Summarizes a workshop at the 1988 AAAS Annual Meeting to examine ethics and values education and research. Issues a series of conclusions and recommendations for expanding and improving work in the field. Notes a need to increase preservice and inservice training in ethics and values studies for science teachers. (MVL)
