This paper presents the procedures, results and conclusions of a study designed to determine whether three different methodological approaches to the laboratory for a general education physical science course would lead to the same behavioral outcomes. Students enrolled in the physical science course were randomized into one of three laboratory…

Compared was the effectiveness of a two-year integrated chemistry-physics course with a two-year sequence of separate courses, in developing understanding of chemistry and physics concepts, understanding science and its methods, and reactions to the study of science. Both groups used the content, materials and instructional approach of the…

Determined were differences in understanding the nature of science and scientists and in subject matter achievement between seventh grade students who studied source papers as part of their instruction in science and those who did not. Experimental students analyzed ten source papers related in subject matter content to the local course of study.…

The effects of the type of earth science course (Earth Science Curriculum Project (ESCP) and non-ESCP), the directness or indirectness of teacher-pupil interaction in various teaching activities (I/D ratio), and the teacher's philosophical orientation (T/NT ratio) on various student outcomes such as understanding of science and scientists;…

The purpose of this study was to describe and exemplify a model to aid schools in introducing and evaluating new instructional programs. Four basic steps are identified: selecting the curriculum goals, identifying a possible program or programs, evaluating the implementation of the program or programs, and developing and obtaining instruments for…

This study measured the effects of teacher-directed and self-directed problem solving techniques on junior high school students' expressed attitudes about science and scientists, their achievement of understandings of science facts and principles, and the rate at which they mastered understandings of the conceptualizations of science necessary to…

THIS INVESTIGATION WAS DESIGNED TO COMPARE CHANGE IN CRITICAL THINKING IN GROUPS OF STUDENTS STUDYING HIGH SCHOOL BIOLOGY IN LABORATORY-CENTERED CLASSES AND IN LECTURE-DEMONSTRATION-CENTERED CLASSES. TWENTY BIOLOGY CLASSES WERE RANDOMLY SELECTED FROM THE FOUR SENIOR HIGH SCHOOLS IN THE SALT LAKE CITY SCHOOL DISTRICT. TEN CLASSES WERE RANDOMLY…
