There were no significant differences in achievement between students using an earth science laboratory block with or without teacher direction. (AL)

Four compulsory introductory activities, involving learning to use a stream tray, observing the relationship between water speed and entraining, transporting and depositing sediments, studying the formation of sedimentary rocks, and examining several types of sedimentary rocks, are completed by all students using the unit prepared for Australian…

Reported is a study to compare science achievement of 318 ninth-grade students who came from different socioeconomic areas but all enrolled in an Earth Science Curriculum Project (ESCP) program. The students were divided into three socioeconomic groups: upper, middle, and lower. All were given a pretest in science achievement, a posttest, an…

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…
