An experiment was conducted on the effects of two teacher variables and student engagement on science achievement. The variables included: teacher wait-time, defined as the length of the pause preceding a teacher utterance; and questioning quality, a generic term used to describe cognitive level, clarity, and relevance of questioning. Thirteen…

Daily newspapers may be used to broaden and enrich the curriculum in both elementary and secondary schools in a variety of ways. The newspaper can be useful in strengthening skills in the language arts and in the social studies and contains information relevant to students of all ages and levels of ability. The variety of topics a newspaper covers…

This paper reports research aimed at understanding how teachers use innovations and suggests that the intentions of teachers, explored through forms of self-report, are an important clue. Eight teachers in three English comprehensive schools participated in a study of their use of the United Kingdom Schools Council Integrated Science Project…

The course outlines presented in this report are intended to be used to teach astrophysics to nonscience majors at the junior and senior college level. An extensive set of notes are included which can be useful to an instructor as guidelines for presentation. Additional equipment and references for use in teaching astrophysics are suggested. (SA)

This guide introduces the study of fossils and means through which this study may provide clues to ancient environments and geology. Presented are discussions about the origin of many types of organisms, origin of organic communities, evolution, and extinction of species. Suggestions are provided for likely collection sites, methods of collection,…

To achieve economy in the teaching of earth sciences, an audiovisual-tutorial program was designed in the pattern of a simulated field trip. Twelve weekly exercises combining slides, filmstrips, and audiotapes were produced and tested on an experimental group of 50 students, who also received one lecture a week. The program was evaluated and…

This article reports on the experience of the Language Centre of Tabriz University in Iran. The Centre is responsible for teaching English in 7 faculties: Engineering, Medicine, Agriculture, Pharmacy, Science, Education, and the School of Nursing. The article first gives the background of the students that are to be taught, followed by an outline…

Audio-tutorial teaching, originated at Purdue University, employs an audio tape as a vehicle for guiding the student through a series of learning experiences. The student may be directed to use his textbook for an explanation of a diagram, to refer to his laboratory manual, or to observe the specimens and experimental materials prepared for his…

Two problem-solving IBM 1130 computers were installed in two New Orleans high schools for a project designed to enrich the mathematics, science, and physics curricula, to provide student motivation through individualized instruction, to develop course materials, to develop programing skills, and to encourage broader computer use in schools. Four…

Steps that should be taken to design and implement computer-based instruction (CBI) for undergraduate science and engineering courses are outlined, and these steps are based on the experience of faculty at the University of Texas at Austin. Among the steps described are development of course material, developmental and validation testing of…

Six areas of computer use in undergraduate education, particularly in the fields of mathematics and physics, are discussed in these proceedings. The areas included are: the computational mode; computer graphics; the simulation mode; analog computing; computer-assisted instruction; and the current politics and management of college level computer…

This report is an evaluation of the attempt of the Boston resource team to improve the physical and educational conditions in the Dearborn school district during the 1970-71 school year. The team identified four goals for its work in the Dearborn annex: (1) improving the physical appearance of the Dearborn school; (2) involving more parents in the…

Describes a technique used extensively in the chemical industry to find and control unanticipated safety hazards. Discusses how a team of individuals can consider how equipment or processes operate and deviations from normal conditions. Suggests this technique could be used in educational laboratories. (TW)

Describes a program in which six experiments in chemistry were used in an elementary school science program. Discusses the problems encountered in initiating the program, and some of the ways the problems were solved. Lists the six experiments, along with the reaction or process being studied, and the application of each. (TW)

Reports on a study that examined and compared the cognitive effectiveness of a traditional hands-on laboratory exercise with a computer-simulated program on the same topic. Sought to determine if coupling these formats would provide optimum student comprehension. Suggests hands-on exercises be followed by computer simulations as postlaboratory…
