Investigated were the proportions of concept types used by fourth through ninth graders to explain scientific terms. Data were collected and analyzed to relate the types of concepts used by students in their explanations to the variables of sex, grade level, and intelligence. An analysis of the types of concepts used by groups of students to…

This is a report of an effort to improve ghetto children's reading in science classes. The writer worked as a consultant with ninth grade general science teachers. The teachers involved in this study used lessons designed by the consultant, as well as materials from commercial publishers. The author reports that there was marked improvement in the…

Included are two of the eight units of the Intermediate Science Curriculum Study materials designed for grade nine students. These are "Why you're you" (genetics), and "Crusty problems" (earth science). The first unit includes basic chapters and "excursions" which extend some of the ideas developed in the basic…

Included is the first half of the chapters and excursions of the Intermediate Science Curriculum Study materials designed for grade eight students. Although I.S.C.S. is an integrated science course, most of the concepts developed in this volume relate to chemistry. Introductory notes to the student explain how the book is to be used. Each chapter…

This teacher's guide to the experimental edition of the second volume of the Intermediate Science Curriculum Study materials includes a general discussion of chemical ideas developed in the course, instructions for preparing solutions and handling equipment, and detailed notes for each chapter and excursion. Chapter and excursion notes give an…

These materials represent the first third of a coordinated science program for grades seven through nine. The materials have been prepared according to the following Intermediate Science Curriculum Study rationale: (1) science at the junior-high-school level should serve a general education function, and (2) both processes and concepts should be…

In 1970 many Australian students, teachers, and schools participated in the International Association for the Evaluation of Educational Achievement (IEA) Science Project. The aim of the project was to measure the science achievement of students in Australia and 18 other countries, and to examine relationships between this achievement and various…

This unit of instruction presents a laboratory-oriented course which relates the sources and behaviors of light to man's control and uses of light. Successful completion of Algebra I and Plane Geometry is strongly recommended as indicators of success. The course is recommended if the student plans further studies in science, optical technology, or…

This unit of instruction presents an individualized mini-course in electricity and magnetism. The course is geared for college-preparatory high school students. A textbook and film bibliography, performance objectives, suggested conditions for completing objectives, a course outline, laboratory activities and suggested resources for the teacher…

This study was designed to assess the use of an individualized laboratory-oriented high school physics program used in one Black Hawk County, Iowa, school. The three problems investigated were: (1) what short-term and long-term learning resulted from the use of the materials, (2) what student characteristics were related to learning outcomes, and…

Reported is a study designed to examine potential explanations for the decline in the percentage of students who enroll in high school physics. Two kinds of factors were assessed: students' stated perceptions of science teaching and teachers and the difficulty components of the science curriculum (particularly the reading level of textbooks and…
