This multidisciplinary, self-contained curriculum unit focuses on the management of the Chesapeake Bay, a threatened and complex environmental system. Major unit goals include identifying and analyzing conflicting interests, issues, and public policies concerning the Bay, and determining their effects on people and the environment. The unit…

Aptitude treatment interaction (ATI) for the two most widely used science teaching strategies (lecture method and lecture method augmented with classroom activities) was investigated. The aptitude variables examined were cognitive ability level expressed in Piagetian terms and cognitive learning style (field independence/dependence). A sample of…

Over 12,000 transcripts from a sample of 1982 high school graduates were collected and analyzed as part of the High School and Beyond Study. The analysis produced four statistics: the average number of years that students took courses in science and mathematics; the percentages of students who had taken three or more years each of science and…

This study examines to what degree opportunities for scientific literacy were provided or denied to college bound and non-college bound students and the extent to which students utilized the available opportunities. An ethnographic approach was employed in this 3-year study of six high schools. Population descriptions and data are presented for…

This unit is one of a group of units written to fit the Certificate of Sixth Year Studies (CSYS) chemistry course, but it could be used in most Sixth Form courses. It includes: (1) teacher notes on contents, methods, and preparation; (2) two sets of data booklets and decision sheets for two new drugs (one data booklet based on 1960 information and…

Many students have difficulty in science because they are passive readers, readers who receive information without understanding. Passive readers begin reading assignments without thinking about the subject. Their counterparts, known as active readers, interact with text to construct meaning. They make predictions, ask questions, generate…

This document is a collection of 43 overhead transparency masters to be used as teaching aids in a course of study involving soils such as geology, agronomy, hydrology, earth science, or land use study. Some transparencies are in color. Selected titles of transparencies may give the reader a better understanding of the graphic content. Titles are:…

This publication is the second product of a project to update and reorder the Science Syllabus for Middle and Junior High Schools in the State of New York.

This study, an extension of previous studies, compared the views of freshmen college biology, chemistry, and physics students (N=229) with those of high school seniors (N=437), focusing on: (1) interest in different high school topics; (2) nature of high school laboratory experiences; (3) use of innovative instructional strategies in high school;…

A self-report instrument (questionnaire/reaction scale) was developed and administered to students in grades 9-12 to: (1) determine the number of science courses taken by each grade level; (2) estimate the number of science courses requested for future years and indicate where recruitment efforts would be needed; (3) examine other-directed reasons…

School science textbooks and reference books used in New Zealand were examined to investigate the types and number of roles assigned to males and females and the place of men and women in the world as implied in science textbooks. Data recorded included the number of different types of roles and activities assigned to each sex, number of times…

Selected materials needed to teach an astronomy unit as well as suggested procedures, activities, ideas, and astronomy fact sheets published by the Manitoba Planetarium are provided.
