Discusses the program's planning phase, some method development projects done by students, experiences received in laboratory operations, and the evaluation of student…

Describes a simple experiment done in a quantitative analysis course that illustrates the chemistry of the breath alcohol test. Discusses the development and use of the Breathalyzer. Outlines the experimental procedure, along with the appropriate calculations and discussion of the results. (TW)

Describes some of the features of Lehigh University's (Pennsylvania) process modeling and control program. Highlights the creation and operation of the Chemical Process Modeling and Control Center (PMC). Outlines the program's philosophy, faculty, technical program, current research projects, and facilities. (TW)

Reports on a study designed to determine the relative effectiveness of different instructional approaches on chemistry laboratory achievement. Investigated differences in achievement in spectrophotometry among college freshmen who received either traditional, learning cycle, or computer simulation instruction. Results indicated that students…

Describes the use of bubble-type plastic packing material to make "pop-and-sniff" materials that contain common smells from chemicals such as amyl acetate (banana smell). Discusses how these materials can be used by elementary school teachers to enhance thinking skills. (TW)

Reports on student attitudes toward science-technology-society (STS) after visiting a science-technology museum and considers what variable factors of the visitation impacted these attitudes. Results indicated that significant differences in attitudes were present between visiting and nonvisiting students and between grade levels. (TW)

Describes a research strategy designed to examine learning and behavior when students interacted with microcomputers and software interfaced with a videotape cassette recorder (VCR). Utilized the VCR to record the video output from the microcomputer and students' verbal comments using a microphone unit. (TW)

Highlights science learning activities and experiences from elementary and middle schools. Includes "Highest Tech Science," an innovative science lab; "Swap Meets," lessons exchanged by mail by two schools; "Students Ahoy," an outdoor experience at the shore; and two cooperative programs between colleges and elementary schools. (CW)

Describes a project in the Bellingham Cooperative School (Washington) in which teachers and students, along with parents and community volunteers, are involved in a 24-acre wildlife enhancement effort. (TW)

Discusses some of the concepts that are central to the courses offered by the Department of Technology and Society at the State University of New York at Stony Brook. Emphasizes the integration of technology concepts into courses dealing with problem solving, space technology, military technology and environmental studies. (TW)

Reports on a study into the perceived problems that foreign graduate students in engineering pose to engineering faculty, as well as the solutions to those problems. Summarizes survey responses relating to communication and language difficulties, program and academic performance, and social and cultural factors. (TW)

Describes a course recently developed at the University of Pennsylvania in mechanical engineering which emphasizes computer applications to laboratory instruction. Discusses the course objectives and explains the computer simulations and experiments utilized in the course. (TW)

Presents a case study of science education in Papua, New Guinea and discusses efforts for implementation of a "Science for All" policy. Includes a description of the physical, cultural, and political setting of the nation and explains its approach to primary, lower secondary, and upper secondary schools. (ML)

Discusses a study of students' conceptualizations and misconceptions of how objects sink and float. Results showed little difference in the levels of understanding of the "sink and float" concepts by groups ranging from primary age to college. As age increased, terminology used by students varied, and misuse of terms increased. (TW)

Describes a collaborative effort involving art, earth science, and computer lessons in teaching the theory and practice of contour mapping. Discusses the approaches and activities contained in the unit for seventh-grade students. Includes the computer program which was written for use with Terrapin LOGO on an Apple II. (ML)
