Described are the use of spreadsheet programs in chemical engineering calculations using Lotus 1-2-3 macros. Discusses the macro commands, subroutine operations, and solution of partial differential equation. Provides examples of the subroutine programs and spreadsheet solution. (YP)

The growth and development, professional development, and recognition of this cooperative program are described. Highlighted is the program in the department of chemistry. Programs in other science departments are also discussed. (CW)

The materials needed and the procedures used in three microscale chemical laboratory experiments are detailed. Included are a microscale organic synthesis, a two-step synthetic sequence for the microscale organic laboratory, and a small-scale equilibrium experiment. (CW)

Described is a microscale organic chemistry experiment which demonstrates one feasible route in preparing ortho-substituted benzoic acids and provides an example of nucleophilic aromatic substitution chemistry. Experimental procedures and instructor notes for this activity are provided. (CW)

Proposed is a three course sequence for all college students designed to raise the level of undergraduate scientific literacy. The rationale, topics to be covered, and an outline of an earth-systems course are presented. Problems in the implementation of such a sequence are discussed. (CW)

Summarized are factors that have been identified as playing a role in the continued strength of the geology department at Carleton College. Discussed are the local environment, curriculum, teaching methods, and the atmosphere of the department. Suggestions for increasing the strength of academic geology departments are provided. (CW)

Discussed are procedures for increasing understanding and appreciation of geology among undergraduates. Included are using student-centered approaches, deemphasizing the use of conventional textbooks, increasing the use of nonspecialized field programs, and increasing the experimental dimensions of geology programs. (CW)

Describes an exercise designed for an introductory level calculus-based physics class. Presents a problem on why a rod dipped in water is stable when it is oriented at an angle with the vertical. Discusses qualitative understanding, mechanical understanding using equations, and experimental verification of the problem. (YP)

Presented are two applications of computer technology to chemistry instruction: the use of a spreadsheet program to analyze acid-base titration curves and the use of database software to catalog stockroom inventories. (CW)

Described is an analytical method that may be used to replace the more difficult, traditional approach for the analysis of silicates. It is argued that this method allows the use of smaller samples and is more sensitive than other techniques. (CW)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)

Introduces three laboratory exercises which develop an understanding of principles of mechanics by using examples of bicycle operation: Newton's laws, statics and dynamics, and energy relationships. Describes related theory and laboratory procedures with diagrams and pictures in each exercise. (YP)

Summarizes the capabilities of a computer program related to forest fertilization. Provides a description of input parameters, some sample exercises, software specifications, and availability information. Additional references are listed. (Author/RT)

Reports that record enrollments have prompted a rethinking of the nation's higher education policies. Cites several explanations for overcrowding: an increase in the number of students continuing their studies, German students take longer to complete studies, and older students are reentering the university. (RT)

Presents four articles dealing with chaotic systems. Lists sources for nine demonstrations or experiments dealing with self-organization. Provides a vocabulary review of self-organization. Describes three chemical oscillator models. Discusses the role of chaos in flow systems. (MVL)
