Outlines a variety of laboratory procedures, discussions and demonstrations including the preparation and analysis of a square planar copper (11) complex, thermit reactions in a sand mould, product solubility, an aid for learning common oxyanions, thermal decomposition of nitric(v) acid. and nine others. (GS)

Outlines a variety of laboratory procedures, discussions, and demonstrations including a no-solder circuit board, damped to maintained oscillations with L-C circuits, polaroid strobe photos, resistive putty, soldering and circuit checking exercise, electromagnetic radiation, square pulses in C-R circuits, and testing an oscillating system. (GS)

Presents notes on the objectives of laboratory instruction, the design of assessment systems on the principles of criterion-referenced measurement, student ability to measure, and student attitudes toward the importance of physics. (GS)

Presents arguments for and against the viewpoint that the teaching of chemistry and of physics should fall in line with modern mathematics. Concludes that modern mathematics has been beneficial in some respects and harmful in others. (CS)

Presents examples of combination, decomposition, replacement metathesis, and neutralization chemical reactions. Suggests that students will gain knowledge of some general trends in the chemical properties of the main group and transition elements by examining reaction types. (JN)

Discusses the use of games to facilitate learning scientific concepts and principles. Describes the Cell Game, which simulates plant and animal cells; the Energy Quest, which requires players to buy property that generates largest amounts of electricity; the Blood Flow Game, which illustrates circulation of blood through the human body. (CS)

Focuses on (1) the current crisis in physics teaching in secondary schools and colleges due to decreases in student enrollment, and (2) the growing shortage of secondary school physics teachers. Discusses reasons for the crisis and presents an approach to solve this problem. (SK)

Describes method for locating images in simple and complex systems of thin lenses and spherical mirrors. The method helps students to understand differences between real and virtual images. It is helpful in discussing the human eye and the correction of imperfect vision by the use of glasses. (Author/SK)

Describes an exercise involving the use of kinematics to decide if one should stop or try and get through an intersection when the traffic light turns yellow. Gives students' experience in recording data, doing simple calculations and connecting classroom studies to real world experiences. (Author/SK)

Investigates the influence of the student teaching experience on the change in attitude toward classroom management in secondary preservice science teachers (N=19). Two measures of classroom management orientation administered before and after the student teaching experience were examined, along with demographic dimensions of gender, science area,…

Reports results of a project focusing on the development of inquiry skills as a goal of science education. Specifies the "desired status" for effective inquiry learning; determines the "actual status" by analyzing four recently completed status studies; and compares desired and actual status to identify needs and recommend actions. (CS)

The Australian Web of Life biology course is evaluated as to its philosophy and mode of instruction. The study reveals that the use of inquiry-oriented practices is relatively low and that teachers consider the objectives of the course more important than do their classes. (Author/DS)

Discusses an aviation/aerospace program as a science elective for 11th and 12th year students. This program is multi-faceted and addresses the needs of a wide variety of students. Its main objective is to present aviation and space sciences which will provide a good base for higher education in these areas. (SK)

Investigates the opinions of 991 Israeli junior high school students with regard to their choices and preferences of science subjects. Findings show that preferred subjects were chosen both from school curricula and from having agents outside the school. (HM)

Described is a science program in Hawaii for high school students in which students are trained in a variety of tasks at a local zoo during the morning hours and then return to campus for coursework. The program offers opportunities to develop responsibility and self-esteem. (SA)
