Studied was the achievement of ability-grouped students enrolled in sections of the biology course at Wausau Senior High School in the years 1963-64 and 1964-65. The biology students in the 1963-64 school year were taught by a team-teacher approach which included large-group presentations. During the second year, the students enrolled in biology…

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…

FACTORS WHICH WERE BELIEVED TO CONTRIBUTE TO STUDENT ACHIEVEMENT WERE INVESTIGATED. THE SAMPLE WAS TAKEN FROM 130 FOUR-YEAR SECONDARY PUBLIC AND NON-PUBLIC SCHOOLS IN SOUTH DAKOTA. STUDENT ACHIEVEMENT IN SCIENCE AND MATHEMATICS WAS COMPARED TO CLASS RANK, AND EXAMINED IN RELATION TO SUCH SCHOOL VARIABLES AS (1) SCHOOL ENROLLMENT, (2) SCIENCE AND…

The purpose of this study was to develop and to evaluate a two-year unified chemistry-physics course at the secondary-school level. Tenth- and eleventh-grade students were placed into experimental and control groups by random sampling with respect to sex and grade level. The experimental and control groups each consisted of 24 students. The…

Investigated was a team approach for teaching high school biology. Students in six high schools in New York state were involved in the study. Achievement gains on tests were compared between students in team approach classes with students in conventional classes. Few differences were observed between groups and many of these were contradictory. It…

RELATIONSHIPS BETWEEN ENVIRONMENTAL AND TEACHER CHARACTERISTICS AND STUDENT LEARNING IN NINTH GRADE SCIENCE ARE INVESTIGATED. NINETY-THREE NINTH GRADE SCIENCE CLASSES WERE SELECTED FROM THOSE TAUGHT IN NORTH CAROLINA. STUDENTS WERE PRETESTED IN THE FALL AND POST-TESTED IN THE SPRING FOR SCIENCE ACHIEVEMENT, UNDERSTANDING OF THE SCIENTIFIC…

Investigated were the outcomes of student participation in science fair projects. The 952 students were stratified for science project experience, choice of career, type of project, type of award, record of project making, motivational factors and reaction to project making. Conclusions included the following: (1) Science projects were not…

Seventeen teachers and a university research team cooperated to compare the effects of team teaching and conventional instruction in biology on student achievement in six high schools in the Rochester, New York, area between 1964 and 1968. Student achievement was measured by the New York State Regents examination in biology, five locally developed…

The sampling of test items found within the Science portion of selected standardized achievement test batteries is examined. The lack of sensitivity of such items to the curriculum changes often attempted in Earth Science is demonstrated. The following five standardized achievement test batteries commonly administered to pupils in grades 7-9 were…
