The purpose of this study was to develop a paper-pencil test of Piagetian levels of proportional thinking for junior high school students in the context of physical science. Two thousand twenty-seven students were tested to develop the instrument and the description of its characteristics. The final form consisted of 24 items with four subtests…

Subjects selected from all the ninth grade intact science classes of a suburban junior high school were assigned to either a control group or one of four intensive instruction groups. The procedures for each instructional group included both watching a discrepant event until six acceptable hypotheses were written and individual discussion during…

This study was conducted to examine the effectiveness of the UNESCO Primary Science Project being piloted in Grade 5 in selected Malawi schools. Specific objectives included determining: (1) differences in performance and attitudes between students following the UNESCO program and students following the old primary science program and (2) problems…

Until 1982, achievement in A-level biology in Kenya was measured by an examination which consisted of four papers, three measuring theory work and one measuring practical skills. In 1982, a three paper examination was developed, the first two papers measuring theory and the third paper measuring practical skills. Based on the change in the test…

In order to study the mechanism of student interest in a physical science course when the majority of students were interested in fields other than science, a system of measuring instruments was applied for detection of significant differences between two teaching methods used for this course. The study utilized the measured responses of 105…

The study was designed to assess the effects of Intermediate Science Curriculum Study (ISCS) Level One in terms of (1) fostering positive growth in the scientific attitudes associated with the nature of scientific laws, the limitations of science, and the desirability of science as a vocation; (2) enhancing the self-reliance level; and (3)…

The purpose of this study was to compare the effects of various teaching practices and classroom organizational patterns upon achievement and understanding of science of students studying materials of the Nebraska Physical Science Project (NPSP), an integrated chemistry-physics course, and to investigate these practices and patterns and the role…

This study was designed as an experimental evaluation of the relative efficiency of designated instructional techniques for student attainment of selected cognitive skills. The sequence in which the student encountered the curriculum, the means by which the student received the information, and the reinforcement effect of an official answer were…

All students enrolling in the day sections of Physical Science 101 at Pensacola Junior College (Florida) during the spring semester of 1974 were allowed to register for either audio-tutorial (A-T) or conventional coursework. The A-T group consisted of 144 students in two sections, and the lecture-discussion group consisted of 76 students in two…

The purpose of this study was to prepare a valid and reliable instrument to evaluate the objectives dealing with the behaviors expected in Part 1 of the Physical Science Study Committee (PSSC) physics course. There were six phases to the study: (1) identification of the processes, (2) selection thereof, (3) construction of instrument, (4) pilot…

The goal of this research study was to develop laboratory materials which would present concepts about plants and selected processes of science to undergraduate elementary education students. Three laboratory exercises, each covering a number of concepts dealing with an identified topic, were used. Behavioral objectives were used to combine major…

This study examined specific student characteristics in seventh-grade students and attempted to make comparisons of these characteristics as a function of their science course program. A total of 109 students participated in Intermediate Science Curriculum Study (ISCS) classes and 106 students participated in non-individualized science classes.…

Reported is a study to identify classroom practices of teachers using three new junior high school science curricular programs. Data from a 36-item student perception instrument, the Student-Teacher Participation Checklist (STPC), were obtained from a sample of 493 students. The teachers of these students were participants in a National Science…

The out-of-school science interest activities of children were investigated in this study. The author sought to update previous findings establishing variations in the science interest activity patterns of boys and girls as well as to relate these activities to different racial groups. An instrument was developed and administered to girls and boys…

This report describes a program for improving scientific literacy at the primary level. The target population consisted of pre-kindergarten and second grade students in an expanding suburban Midwestern community. An intervention which included the identification of scientific skills and their integration into the curriculum, student exposure to…
