This study ascertained whether or not computer assisted instruction (CAI) enhanced the quality of the educational experience and resulted in increased learning. The study involved the teaching of a 3-week instructional unit on population genetics and evolutionary processes to advanced placement biology students. The control group (N=38) received…

Presented in this document is a full-year, two-semester course in geology for high school students. Composed of 5 units and 20 chapters, the course emphasizes the practical aspects of geology with special attention to the relationship between geoscience processes and the environment and to the application of scientific and technical expertise to…

The 1982 Yearbook of the Association for the Education of Teachers in Science (AETS) is the second in a series of three AETS yearbooks in which Ralph Tyler's 1949 curriculum rationale is used to analyze science curriculum. This publication is focused on the secondary school science curriculum (the 1981 yearbook was concerned with teaching science…

From 1968 to 1970, three separate studies of North Carolina science teachers were conducted in the areas of biology (N=177), chemistry (N=101), and physics (N=71). The three studies shared three major purposes, to determine: the academic preparation of the science teachers being investigated, (2) the relationship between the level of academic…

For the past two decades, increasing numbers of scientists have been optimistic about finding other intelligent life forms in our galaxy. On the other hand, as knowledge has grown regarding how life developed on earth, a scientific counterrevolution has evolved. Simply stated, it questions the inevitability of widespread life within our galaxy,…

Following a list of objectives for secondary school science for Alberta (Canada), science objectives for grade 7 (biological sciences), grade 8 (earth science), and grade 9 (physical science) are presented in three separate sections. These objectives are related to key concepts listed in the table of contents. The format of each section is the…

One of the most striking developments in understanding science learning has been the discovery of the extent and persistence of the naive conceptions about the natural world students bring with them to the classroom. In physics and other sciences, students (even those who do well on textbook problems) often do not apply principles they have…

Seven activities are included in this 10 day secondary school science unit in which students determine the effect that auto exhaust fumes have on the air they breathe by utilizing laboratory experiences, independent research, and in-class discussions. Rationale, objectives, and instructional strategies are provided for each activity. Following two…

The major objective of this module is to help students understand how water from a source such as a lake is treated to make it fit to drink. The module, consisting of five major activities and a test, is patterned after Individualized Science Instructional System (ISIS) modules. The first activity (Planning) consists of a brief introduction and a…

Students have well-formed but incorrect theories of simple motion. As children, they interpret many phenomena related to motion before encountering any formal science education. Since most adults have misconceptions, children's questions are not answered correctly, so the misconceptions persist. Thus, every science teacher must face the prospect…

This handbook is designed to meet the aquatic education needs of Minnesota secondary teachers and students (aquatic education referring to the study of freshwater systems). The handbook is divided into three parts. Part 1 (an introduction) provides an overview of aquatic education, a description of the use of the handbook, and two indices to…

Designed as enrichment materials for grades six through nine, this program is an interdisciplinary study of soils. As part of the program students: (1) examine soil organisms; (2) research history of local Native Americans to see how they and others have used the land and its soils; (3) investigate how soils are degraded and how they are conserved…

High school students interested in ocean-related careers will find their imagination piqued by "Ocean Opportunities." As the ocean's resources are recognized more and more as extremely important economically, yet very fragile, study of those resources is burgeoning. This multi-color booklet describes the exciting opportunities which ocean research…

The multiple-choice test items collected in this volume were selected from questions submitted by teachers in New South Wales for the Science Library of Test Items. The collection is intended as a resource to assist teachers in implementing and evaluating courses in the first 4 years of Australian secondary school. To ensure quality in the…

The second volume of test items in the Science Library of Test Items is intended as a resource to assist teachers in implementing and evaluating science courses in the first 4 years of Australian secondary school. The items were selected from questions submitted to the School Certificate Development Unit by teachers in New South Wales. Only the…
