Relates some teaching experiences and observations of the 1976 recipient of the James Bryant Conant Award in High School Chemistry Teaching. (MLH)

Discussed are (1) the changes in secondary school science courses in Australia; (2) factors influencing these changes, particularly external assessment of grade 12 students; and (3) the introduction of physical science as a new subject. (SL)

Described is a three-level self paced high school chemistry course developed for Queensland, Australia schools. The design involves a modification of the Keller Method. A sample unit test is included. (SL)

Described is a physics experiment in which small bits of metal on a water surface will move towards, and away from an electrostatically charged rod. The explanation for the motion of the metal bits deals with their shape and the electrical force on the water surface. (SL)

Described is a personalized self-instruction science program implemented at Cambridge School, Boston. The program consists of five-week modules, in each science area, which the students select. (SL)

Discusses a Japanese secondary school curriculum that emphasizes two themes: light and substances, and the earth and living things. Examines the way several specific topics are taught, and presents an overall course outline including approximate hours spent on each topic. (MLH)

Results of pre- and post-testing the tree identification skills of a group of 4-H members showed that adolescents aged 9-11 respond better to lecture demonstration teaching methods, while adolescents aged 12-14 respond better to an inquiry process that used nature trails as the primary instructional tool. (MLH)

A description of four rapid tests to determine the viability of stored seeds are given. Typical results are reported and some possible applications of the tests are discussed. (Author/EB)

This study compared two groups of high school biology students and teachers with respect to teaching method and resultant behavior, learning climate, and achievement. The use of an open-inductive method yielded significantly different results from the traditional deductive method of instruction. (JR)

Reports the results of an investigation of the accuracy of self-evaluation on test performance, in which junior high school students were asked to predict their scores before and after taking each unit test. Some students learned to improve their evaluations of self-performance on cognitive tasks without formal instruction. (JR)

Discusses the advantages of visiting a science museum to supplement the school science program. Lists 20 major science/technology centers, and in particular, describes the main attractions at the Chicago Museum of Science and Industry. (JR)

Briefly describes the ecology of a deciduous forest, and suggests activities for observing and appreciating the changes that occur during the Fall. Simple experiments relating to mosses and lichens are outlined. (JR)

Describes the experimental procedures used for detecting DNA and RNA synthesis in xenopus cells by autoradiography. The method described is suitable for senior high school laboratory classes or biology projects, if supervised by a teacher qualified to handle radioisotopes. (JR)

Discusses applications of techniques developed for the remote sensing of infrared radiation. In addition to military applications, remote sensing has become important in collecting environmental data and detecting ecological problems. (JR)

Presents an interim report on a study of the interaction between secondary school chemistry and mathematics, which was undertaken by the British Committee on Chemical Education. (JR)
