Engaging students in both hands-on and minds-on experiences is needed for education that is relevant and complete. Many middle school students enter science classrooms with pre-conceived ideas about their world. Some of these ideas are misconceptions that hinder students from developing accepted concepts in science, such as those related to…

A pedagogical experiment is described to examine the physical absorption of gases, in this case carbon dioxide, in a hollow fiber membrane contactor (HFMC) where the absorption concentration profile can be followed by a color change. The HFMC is used to teach important concepts and can be used in interesting applications for students, such as…

This document is the final report to develop a new elementary science curriculum. It contains information related only to the development phase of the Conceptually Oriented Program in Elementary Science (COPES) and was written for an audience that includes all who are interested in curriculum development as it was experienced in this project. The…

Reported is a preliminary effort at the development of a lesson-writing paradigm. Changes in the verbal behavior of seventh-grade pupils during their study of the first eight chapters of Volume 1 of the Intermediate Science Curriculum Study (ISCS, 1968) were related to the frequency of occurrence of the concept words in the instructional material.…

This looseleaf teacher's manual is designed to facilitate using Science Curriculum Improvement Study (SCIS) for energy education in elementary schools. It is intended to be used with the SCIS Teacher's Guide as a supplement. The format of this manual matches a main SCIS concept with a closely related energy concept. Matrices show matched concepts…

A six-year project providing training for prospective elementary school science teachers is described. Phase one, a period of three years, involved a longitudinal study of a pilot group of students as they encountered science content and science teaching methodology, coupled with early and continued field teaching experiences. In the final three…

To further evaluate a method of content analysis and aid in identifying scientific concepts appropriate at the elementary level, science material in a standard textbook series was examined. This paper reports and summarizes the analysis of sections of the California state-adopted textbook series, "Concepts in Science." The conceptual…

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…

This study is part of a larger study of teachers' use of curriculum materials in planning and teaching fifth-grade science. The study focused on one of nine teachers observed teaching "Communities," an activity-based unit from the SCIIS science program (a revision of the original Science Curriculum Improvement Study).…
