Some researchers have argued that it is important to match teaching styles with students' learning styles, although a relatively small amount of research has been done on learning styles in science. This study focused on the differences between male and female secondary school chemistry students in an effort to determine the relationship of gender…

To investigate the effect of outside help in executing a successful science fair project, surveys were distributed to 356 participants in the 1987 Mississippi Region V Science Fair. Of this number, 147 students were in grades 7 and 8, 136 in grades 9 and 10, and 73 in grades 11 and 12. Students listed the number of hours they spent using outside…

This report includes three experiment sections. The first experiment tested sensitivity to loss in altitude and demonstrated that: (1) preview effects led to adaptation; (2) sensitivity decreased with higher flow rates; and (3) sensitivity increased with higher optical texture densities and fractional loss. The second and third experiments…

Seven activities are included in this 10 day secondary school science unit in which students determine the effect that auto exhaust fumes have on the air they breathe by utilizing laboratory experiences, independent research, and in-class discussions. Rationale, objectives, and instructional strategies are provided for each activity. Following two…

The major objective of this module is to help students understand how water from a source such as a lake is treated to make it fit to drink. The module, consisting of five major activities and a test, is patterned after Individualized Science Instructional System (ISIS) modules. The first activity (Planning) consists of a brief introduction and a…

The objective of this environmental studies unit is to establish a water quality monitoring project for high school students in Alberta while simultaneously providing a unit which meets the objectives of the Biology 20 program (and which may also be used in Biology 10 and 30). Through this project, students assist in the collection,…

This report presents the methodology and findings of a national survey of the performance of approximately 9,000 11-year-old children in science. Performance was assessed in six categories: (1) symbolic representation (reading information from graphs, tables, and charts); (2) use of apparatus and measuring instruments; (3) observation; (4)…

Listed in this science syllabus are concepts and understandings in five areas of astronomy (earth, studying the heavens, earth's moon, the sun and other stars, and the solar system) and two areas of aerospace science (flight in air and flight in space). Included with these The booklet also includes questions for students to answer and, when…

Analytical and experimental methods are used to determine the natural frequencies and mode shapes of Aluminum 6061-T651 beams with rectangular and circular cross-sections. A unique test stand is developed to provide the rectangular beam with different boundary conditions including clamped-free, clamped-clamped, clamped-pinned, and pinned-pinned.…

In the framework of a curriculum reform in the Netherlands, an interdisciplinary open inquiry assignment has been introduced as a part of the final secondary school examinations. We developed and evaluated a preparatory open inquiry assignment to be used in science and mathematics departments of schools, in collaboration with each other: the…

This paper reports two studies that examined changes in the participants' level of moral reasoning after exposure to the Kohlberg cognitive-developmental intervention model (1975). This approach focuses on universal moral principles which are manifested in a series of developmental stages. Knowledge of these stages provides one with an outline for…

The performance of two groups of adult students on the General Educational Development (GED) test was compared to determine whether there was a relationship between the level of student performance on a timed versus non-timed GED test. Each group consisted of the first three hundred students who took the test at twenty-six different testing…

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

"Science for the Seventies" (SFTS) is designed to aid teachers and administrators by helping them select materials from available elementary science programs, modify on-going science programs, or develop a better science curriculum. SFTS encompasses 16 televised programs which provide introductory experiences appropriate for launching a…
