Preservice teacher education, when viewed through a constructivist lens, should consider preconceptions because it is important that students be initially aware of their own attitudes and of the beliefs that they carry with them. Preconceptions also provide a reference point about which students may reflect as new meanings are acquired. This paper…

Scientific literacy seems to be one of those recurring preoccupations in the scene of science education in the United States. As usual, the science education community is not unanimous about there being a crisis. There is either a healthy pluralism and ongoing discussion or a complete lack of orientation in science education on this topic.…

Students at the secondary and postsecondary levels exhibit difficulty in the oral reading of scientific terminology, in part because of the abundance of polysyllabic words derived from Greek and Latin. Some of the problems observed include faulty stress placement, vowel insertion and deletion, vowel discrimination, and consonant insertion. Such…

Due to data released in several reports in recent years, concern has been growing regarding the status of undergraduate science in two-year colleges, four-year colleges, and universities. Recommendations of reports on this topic are summarized. Types of programs and activities that have been developed with precollege schools and students; current…

The search for new energy resources as alternatives to fossil fuels have generated new interest in the heat of the earth itself. New geothermal areas with a variety of characteristics are being explored, as are new ways of extracting work from naturally heated steam and hot water. Some of this effort is discussed in this three-part module. Five…

Variables to predict grades in a noncalculus, preprofessional college physics course at Xavier University of Louisiana, a historically-black institution, were identified using linear regression. The two-semester, noncalculus physics course emphasizes the application of physics in the health professions. The study population consisted of 123…

The "Unesco Reports in Marine Science" are designed to serve as a complement to the "Unesco Technical Papers in Marine Science." This report focuses on the current situation in marine sciences in Arab universities. A special meeting was convened in Jordan during December, 1985, to discuss the objectives of teaching and research…

This paper analyzes the hardware and software features that would be desirable in a computer-based semantic network system for representing biology knowledge. It then describes in detail a prototype network of molecular biology knowledge that has been developed using Filevision software and a Macintosh computer. The prototype contains about 100…

A promising new development in science education is the use of microcomputer-based laboratory tools that allow for student-directed data acquisition, display, and analysis. Microcomputer-based laboratories (MBL) make use of inexpensive microcomputer-connected probes to measure such physical quantities as temperature, position, and various…

Chemical engineers play a key role in industries such as petroleum, food, artificial fibers, petrochemicals, plastics and many others. They are needed to tailor manufacturing technology to the requirements of products and to integrate product and process design. This report discusses how chemical engineers are continuing to address technological…

A cadre of thinkers called cognitive scientists has been investigating some of the same issues that first possessed the Greeks. As did the Greeks, they seek to understand what is known, ponder the sources of knowledge, conjecture about the various vehicles of knowledge, reflect on language, and speculate on the nature of the activity of knowing.…

The College Board's Advanced Placement (AP) biology program is explained and options within it are explored in this guide for teachers. Experienced AP biology teachers were surveyed for information concerning approaches that were effective in their programs. Descriptions and suggestions from the 14 respondents are reported in the area of: (1)…

This study was designed to determine if the final grade in college biology at a suburban community college was a true measure of student's knowledge. One hundred and seventy undergraduates taking a semester course in biology took part in the study. This population was randomly separated into a control, placebo, and experimental group. The progress…

Research has shown that nuclear radioisotope power generators can supply compact, reliable, and efficient sources of energy for a broad range of space missions. These missions range from televising views of planetary surfaces to communicating scientific data to Earth. This publication presents many applications of the advancing technology and…

This four-chapter resource book provides both general and specific state-of-the-art information on the various technologies and strategies available to educators of physically handicapped students in "regular" junior/senior high school and college science classrooms. It provides information about accommodating students with physical…
