Discusses use of microcomputers for grading, simulating laboratory experiments, data collection, and for communicating with students. Database systems, word processing, and an electronic spreadsheet program are also considered. Programing tips for several of these areas are included. (JN)

A brief review of the mole concept and its application is given, major problem areas are highlighted, and suggestions are made for a unified approach to alleviate some of the student misunderstanding when preparing solutions, calculating concentrations, and determining effects of dilution. (Author/JN)

Proposes a method for dealing with units that require involvement of units of each physical quantity at every stage of a calculation. Preliminary ideas on algebra and the concept of a physical quantity, equations relating two or more units, calculations of physical quantities, and logarithms are considered. (JM)

Recent studies indicate that industries desire college graduates who are able to perform scientific technical skills. As a result, colleges are attempting to produce graduates with a hybrid course of study emphasizing skills and traditional theories. Programs in chemistry, ecology, urban planning, and science technology have been developed…

Cites three historical anecdotes dealing with chromatography, the bioinorganic chemistry of iron, and the Pauli effect. (MLH)

Papua New Guinea is a young, developing nation, achieving independence in 1975. Industries which can be classified as chemical industries by western standards, are almost non-existent in Papua New Guinea. As yet, most of the raw materials it produces are exported to other countries to be processed or manufactured into useful products. However,…

This book is designed for middle school earth science or physical science teachers to help their students learn scientific literacy through event-based science. Unlike traditional curricula, the event- based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork,…

It has been found repeatedly that when test takers are allowed to choose a subset of constructed response (CR) items to answer on a test, they tend to choose differently and often perform lower on more popularly chosen items. This study investigated the psychological factors that influence test takers choices. Using an experience that incorporated…

This paper discusses a research project that investigated the effectiveness of student surveys administered to eighth grade students on student involvement and learning. The surveys are called "Thinking About" and are presented at the beginning of each chapter in Core Science Textbooks. Two exercises were chosen for the study--chemical or physical…

This book contains questions for secondary school science students that require them to analyze data presented in various forms and apply knowledge and skills developed in novel situations. The content for the questions is derived from a science curriculum developed by a group of Caribbean nations. The material is organized into four sections: (1)…

An action research framework is used to learn what cooperative learning activities mean to students in a physical chemistry course, to discover how the activities can be improved, and to learn how students' perception of cooperative learning changes. Through an analysis of field notes and a student questionnaire, two findings emerged which…

The purpose of this safety manual is to provide a resource to help manage and minimize potential risks in science classrooms where students spend up to 60% of instructional time engaged in hands-on activities. This manual contains information on standards, legal aspects, and responsibilities for science safety; general laboratory safety for…

This book is designed to assist teachers at the 9-12 grade levels in addressing the goals of the National Science Education Standards (NSES) in their own classrooms concerning the teaching and learning of chemistry. The Standards expect students to learn science in an active manner and emphasizes methods of inquiry and deductive reasoning based on…

This paper argues for extending the definition of "technology" in education to include much more than just computers, and for recognizing the dangers of using technology for its entertainment purposes. Two conceptions of the proper use of technology in science classrooms are offered: (1) technology as tool; and (2) technology as topic. Specific…

The nature of the relationship between graduate student and advisor is perhaps the most important determinant of a student's success or failure in any graduate program. This relationship is even more important in science where in addition to being the student's advisor and mentor, the advisor is usually the head of the laboratory in which the…
