This project consisted of an analysis of United States' data collected during the Second IEA Science Study (SISS). It focused on the differences in achievement scores between female and male participants at Grades 5, 9, 10, 11, and 12. A manipulative process test, as well as the written achievement test, was administered to students in grades 5…

The purpose of this study was to: (1) assess the reasoning levels of students using the Longeot Test; (2) compare the background of each student with the student's reasoning ability; and (3) identify which factors would best determine a student's reasoning level on the Longeot Test. The sample consisted of 636 students (336 females and 300 males)…

This paper is part of a paper set which addresses the potential contributions of teacher effectiveness research to science teacher education. The goal of the study is to assess selected research-based teaching and observation practices in combination with an effective staff development procedure in the context of science education. Two techniques,…

This report synthesizes the findings of the Illinois statewide curriculum census projects of 1977 and 1982. The census was designed to produce normative data relative to offerings and enrollments in Illinois public secondary schools and establish a source of information on secondary school curriculum. Statistical information include: (1)…

A study determined the degree of importance secondary vocational instructors place on students' possessing science skills for successful completion of their vocational program. It also determined the specific skills in biology, chemistry, and physics the instructors taught and identified the secondary vocational programs that require students to…

This four-part booklet examines various issues related to nuclear weapons and how they will affect an individual working as a scientist or engineer. It provides information about the history of nuclear weapons, about the weapons industry which produces them, and about new weapons programs. Issues are raised so that new or future graduates may make…

A brief summary of data gathered from the Survey of Earned Doctorates during the academic year 1976-1977 is presented in this, the eleventh in a series of yearly summaries of data, a series that began in 1967. Data was obtained from questionnaires filled out by the graduates as they completed all requirements for their doctoral degrees, and refers…

The postbaccalaureate plans of 1980-1981 physics and astronomy graduates were surveyed and compared with previous graduates. Data are presented on annual changes in postbaccalaureate plans during 1971-1981 with respect to the following options: physics graduate study, other graduate study, civilian employment, military service, and undecided.…

This series of…

Results of the Survey of Enrollments and Degrees for physics and astronomy programs are presented. The changing numbers of institutions (doctoral, master's, and bachelor's) during 1977-1982 are indicated and institutions are classified by highest physics degree offered. Tables provide the number of physics degrees granted 1970-1981, by the three…

Following a brief description of the major components found effective in school safety programs (safety management, education, and services) and data on school accidents in Iowa, this book addresses various aspects of safety related to science instruction, emphasizing that responsibility for safety must be shared by both teacher and students.…

A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

A survey of 1978-79 graduate degree recipients in physics and astronomy was undertaken to determine the characteristics of students and employment opportunities. Information is presented on: employment offers for new physics masters and doctorate recipients, 1974-79; characteristics of the 1978-79 graduate physics student population, and of…
