On the basis of studies reported elsewhere (SE 019 717 and 719) the author discusses the implications of research on cognitive development for teachers whose subjects involve an understanding of proportionality. Several common methods of teaching chemistry students to use proportionality in chemical problems are described. Research on the…

"Quest into Matter," produced by Ontario (Canada) Instructional Television, aimed to investigate the "heart of matter" at the college freshman level of chemistry. Specifically, its purpose was to demonstrate the relevance of "shape" in relation to the properties of matter from the molecular level to the galactic. Some…

This article presents the subject of English for Specific (or Special) Purposes (ESP) from the point of view of the school teacher or university lecturer attempting to teach science to students for whom the medium of instruction is a second language. The skills a student needs in order to achieve success in a science are analyzed as: (1)…

Science requirements in home economics undergraduate programs and contributions of science courses to home economics classroom teaching were investigated. Following a review of related literature, college catalogs were surveyed to determine what proportion of American home economics departments required chemistry courses to obtain a bachelor's…

This study was designed to determine if students taking junior high school science would receive greater understanding and retention of science principles and procedures from the Earth Science Curriculum Project (ESCP) than would students taught grneral science via the lecture-demonstration method. No attempt was made to group the students (28 in…

An audiotutorial approach to problem-solving in college chemistry relying upon audio tapes is available. The program is designed to increase the teacher's effectiveness by providing individualized attention to student difficulties related to problem-solving. Problem solutions are recorded on audio tapes (designed for use with Sony TC-160 cassettes…

A computer-assisted instructional program used at the United States Naval Academy to provide students in introductory physics with practice in problem-solving is described. The author first discusses the rationale for using a time-shared, tutorial approach and presents the steps involved in building a tutorial problem drill. Following this, the…

The Paris Faculty of Science is developing programs in computer-assisted instruction (CAI). Their first goal is to develop "questionnaires" (instructional sequences) administered by teletype machines which check on a student's knowledge in an area and draw his attention to basic concepts, definitions, and theorems in that area. Using an…

This curriculum guide permits the use of a great variety of materials and encourages creativity on the part of teachers and children. Listed are suggested activities to be considered as minimum learning experiences, leaving each teacher with the freedom and responsibility to provide variety and achieve individualized educational experiences for…

THREE APPROACHES TO INSERVICE TEACHER EDUCATION WERE EXAMINED TO DETERMINE WHICH WAS MOST EFFECTIVE IN PREPARING TEACHERS TO USE A NEW CURRICULUM IN SCIENCE. THE CURRICULUM, "SCIENCE - A PROCESS APPROACH," HAD BEEN DEVELOPED THROUGH EFFORTS OF THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE FOR SCIENCE INSTRUCTION IN GRADES K-3.…

An instructional television program, "Place of Doors," developed by the New York State Education Department's Bureau of Educational Communication to teach science, ecology, health, social studies, and consumerism to fourth graders was evaluated. The program was used to provide mainline rather than supplemental instruction. Nine hundred…

This handbook is designed to assist teachers of technical mathematics in developing practically-oriented curricula for their students. The underlying assumption is that, while technology students are not a breed apart, their needs and orientation are to the concrete, rather than the abstract. It describes the nature, scope, and content of…

Lists 40 things to do to have a safer chemistry laboratory. Discusses the evolution of these guidelines for schools from safety suggestions originally developed by industry. Categorizes the 40 steps into those requiring minimal cost and those requiring moderate expense. (TW)

Discusses the properties of carbon dioxide in its solid "dry ice" stage. Suggests several demonstrations and experiments that use dry ice to illustrate Avogadro's Law, Boyle's Law, Kinetic-Molecular Theory, and the effects of dry ice in basic solution, in limewater, and in acetone. (TW)

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)
