Outlined is a specific computer application which can be used to analyze data on plant community composition from the point quarter sampling method. Procedures, examples of spreadsheets prepared in this manner, and evaluation of the activity are presented. (CW)

A collection of Molecular Orbital (MO) programs that have been integrated into routines and programs to illustrate MO theory are presented. Included are discussions of Computer Aided Composition of Atomic Orbitals (CACAO) and Walsh diagrams. (CW)

Presented is an experiment which demonstrates principles of experimental design, solubility, and crystal growth and structure. Materials, procedures and results are discussed. Suggestions for adapting this activity to the high school laboratory are provided. (CW)

Reviewed are six computer programs which may be useful in teaching college level chemistry. Topics include dynamic data storage in FORTRAN, "KC?DISCOVERER," pH of acids and bases, calculating percent boundary surfaces for orbitals, and laboratory interfacing with PT Nomograph for the Macintosh. (CW)

Stressed is the importance of helping students to become independent of their instructors in gathering information. Information-gathering skills are enumerated and teaching methods are suggested. A brief annotated bibliography and definitions of materials are provided. (CW)

A course designed to teach library research skills to engineering students is described. Discussed are the objectives, method of instruction, student performance, and evaluation for this course. (CW)

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

Described is a course that attempts to demonstrate the relationships that exist between science and business. Emphasized are the roles that scientific analysis and scientific knowledge and technology play as vital tools in management decision making in business. (KR)

The process of choosing a scientific major was examined in a nationally representative sample of 2,592 male and female college students of above-average ability. Socioeconomic status, high school teacher and guidance counselor influences, family and personal life priorities, and attendance at a four-year college were predictive factors. (TJH)

Described is a simple test which uses micro- and macro-observations of onion root tips to demonstrate mutagenic and other toxic effects of various contaminants. Discussed are materials, methods, microscopic procedures, and applications of this activity. (CW)

Students' conceptions of the concept of force are discussed. Possible problem formats and exercises are presented. The need for many formats and variations to help students' resolve their conflicting ideas about physics concepts is stressed. (CW)

Reported is a profile of nonmajor instruction determined through a nationwide survey of college and university professors who teach introductory courses to non-science majors. The purpose of the survey was to identify the critical issues and problems that exist related to this population of students. (KR)

Described are ideas for the development of problem solving in the context of chemistry. Strategies for improving students' problem solving abilities are included. (KR)

Presented are the results of a study of the effects of peer-led tutoring groups on achievement in college chemistry. Supplemental instruction was effective in increasing students' achievement in chemistry as measured by final grades in chemistry and responses to a questionnaire. (CW)

Discussed are hazardous substance regulations in Great Britain which effect science teaching at the secondary and college level. Included are background information, immediate implications for schools and colleges, and risk assessments concerning biology classrooms. The responsibilities of Local Education Associations are highlighted. (CW)
