Assesses the level of intellectual development in proportional, combinatorial, and correlational reasoning and the ability to control variables in beginning sophomore students (N=207) at the American University of Beirut, Lebanon. Compares this level with their performance on achievement tests in mathematics, biology, chemistry, and physics. (CS)

Presents data on reasoning abilities of science and non-science majors at one private, liberal arts university. Indicates that most students taking physics are formal operational or into transition to formal reasoning and that six concrete operational students dropped the course. (JN)

Investigated proportional reasoning abilities of 35 college science students using projection of shadows problem while presenting relevant only or relevant/irrelevant information. Field independence was measured using Group Embedded Figures Test. Students in relevant only condition performed significantly better. Degree of field independence…

Discusses debt financing as a way to help universities alleviate the problems of obsolete scientific equipment and facilities for research. Reviews several forms of tax-exempt financing and takes note of some of the advantages of debt financing. (CS)

Discusses the oscillatory motion of a mass on a spiral (nonhelical) spring, and calculates the lowest eigenfrequency and the associated effective spring mass for a range of values of the attached mass. Analytic and numerical comparisons are made to the helical spring problem. (HM)

Describes an undergraduate experiment which uses derivative spectroscopy to investigate the validity of the Planck function appearing in the blackbody radiation law. These measurements allow a critical examination of this function and also serve as an introduction to derivative spectroscopy techniques. (Author/HM)
