Presents information on the perceptions of students (from third, seventh, and eleventh grade) and young adults concerning science classes, their science teachers, and the value of science content. Includes data from the Third Assessment of Science (1977), National Science Supervisors Association Study (1982), and National Science Teacher…

Describes five ways that high school students explain a chemical change. Discusses the differences in conceptual understanding of the students based upon their responses to questions about simple reactions. Presents additional classifications of conceptions of chemical reactions done by other researchers. (TW)

Describes the rationale for using computer-assisted videodisc lessons to enhance introductory chemistry courses at University of Illinois, and presents sample lessons to illustrate what students see and do as they proceed through the lessons. Lesson construction and use are reviewed. (MBR)

Describes laboratory exercises which demonstrate a new simplified technique for deforming thin samples of crystalline materials on the stage of a petrographic microscope. Discusses how this process allows students to see the development of microstructures resulting from cracking, slipping, thinning, and recrystallization. References and sources of…

Contains the appendix for the Naturescope issue dealing with wetlands. Includes a glossary of terms, a partially annotated bibliography (categorized into general reference books, field guides, childrens books, audio-visual materials, booklets, kits, maps, posters, other activity sources and courseware), and an index to the magazine "Ranger…

Describes several laboratory experiments that are adaptations of clinical tests for certain genetic diseases in babies. Information and procedures are provided for tests for phenylketonuria (PKU), galactosemia, tyrosinemia, cystinuria, and mucopolysaccharidosis. Discusses the effects of each disease on the infants' development. (TW)

Examines the hypothesis that there are preliminary stages in problem solving that are often neglected in teaching chemistry. Discusses correlations calculated between the student's ability to handle disembedding and cognitive restructuring tasks in the spatial domain and ability to solve chemistry problems. (TW)

Describes a school-wide science event which focused on the theme of earth in space. Reviews how the teach-in was organized and includes examples of student involvement. Provides a listing of activities and topics for grades K-6. (ML)

Discusses faculty development efforts within the medical education field. Argues that most faculty development programs primarily stress instructional improvement. Urges that increased attention be given to other responsibilities of faculty besides teaching, the varying needs of faculty at different career stages, and needs identified by faculty…

Describes a teaching game designed to train clinicians about effective management practices and strategies. Provides the goals and objectives of the same, along with the specific instructions for participants involved in this simulated operation of an imaginary health center. (TW)

Addresses some concerns about the safety of handicapped students in school science laboratories, along with some of the litigating factors involved in not addressing those concerns. Offers some general suggestions for teachers in working with handicapped students, and describes specific laboratory teaching approaches for students with different…

Presents a technique for eliminating errors in the analysis of the nickel subgroup of the aluminum-nickel group cations. Describes the process of color and chemical changes that occur in this group as a result of ligand and coordination number changes. Discusses opportunities for student observations. (TW)

Describes a high school chemistry student's research project in which limonene was isolated from the oil of lemons and oranges. Outlines the students' tests on the use of this chemical as an insecticide. Discusses possible extensions of the exercises based on questions generated by the students. (TW)

High school counselors in Virginia were surveyed on their recommendations for academic programs in science and mathematics for fictitiously named male and female students at different levels of academic achievement. The counselors were apparently not influenced by the sex of students. (MNS)

Addresses the need to present beginning chemistry students with a variety of experiences dealing with chemical reactions to develop the individual student's concept of these processes. Presents information and experiments dealing with the heat effect of chemical reactions. Includes a discussion on exothermic and endothermic processes in laboratory…
