Background. The purpose of this study was to examine the cross-sectional and longitudinal influence of specific social-cognitive variables on students' physical activity behavior across the first college year. Methods. First-year college students (N = 406) from a regional higher education institution participated. Email solicitation was sent to…

Current educational reform calls for increased integration between science and mathematics to overcome the shortcomings in students' quantitative skills. Data Nuggets (free online resource, http://datanuggets.org) are worksheets that bring data into the classroom, repeatedly guiding students through the scientific method and making claims…

Condensed norms are presented for the most recent American Chemical Society examinations. These are the polymer chemistry form 1978, organic chemistry form 1978, physical chemistry form 1976 I, brief qualitative analysis form 1977B, and brief organic chemistry form 1977B examinations. (BB)

Provides statistical data of female representation in college, engineering majors, and engineering careers in Italy. Discusses the reasons for choosing engineering as a major field and the difficulties of the choice. (YP)

Described is a method for the illustration of the statistical nature of measurements in quantum physics by means of simulation with pocket calculators. The application to examples like the double-slit experiment, Mott scattering, and the demonstration of the uncertainty relation is discussed. (Author/HM)

Presents degree and employment statistics on women scientists and engineers, outlining variations through the years and by fields. Several factors contributing to the difference between women's proportion of degrees and their proportion of the labor force are discussed. Also presents starting salary differences and types of employers. (DH)

Discusses: research and development (R&D) spending by government agencies; federal support for specific areas of R&D; outlays for R&D by the chemical industry and individual chemical firms; manpower in industrial R&D; and sources of R&D funds for universities/colleges. Detailed statistical tables are included. (JN)

Provides statistics of 1988 engineering and engineering technology enrollments surveyed by the Engineering Manpower Commission. Presented are tables showing the 10-year trend, enrollment by curriculum, and enrollment by schools for all students. (YP)

Discusses the results of the 1975 Examination for General Chemistry, and summarizes descriptive statistics as well as ten different subsets of instructional topics. The major results and conclusions are reported in three separate profiles. (HM)

This report is the Chemical and Engineering News' annual compilation of data on research and development. Sections include overview, federal government, industrial, and university data. Tables and graphs are used to present most of the information. (YP)

In this article we describe the development of the Chemistry Attitudes and Experiences Questionnaire (CAEQ) that measures first-year university chemistry students' attitude toward chemistry, chemistry self-efficacy, and learning experiences. The instrument was developed as part of a larger study and sought to fulfill a need for an instrument to…

Research which makes possible a quantification of the size, composition, and growth of the underclass is discussed. Trends in the quality of life and the growth of the underclass are presented. (CW)

Outlines the simple exercise of measuring the length of an object as a concrete paradigm of the entire process of making chemical measurements and treating the resulting data. Discusses the procedure, significant figures, measurement error, spurious data, rejection of results, precision and accuracy, and student responses. (TW)
