Undergraduates from chemical engineering, applied chemistry, and environmental science courses, together with first-year postgraduate research students in electrochemical technology, are provided with an experiment that demonstrates the reduction of dissolved oxygen in aerated seawater at 25°C. Oxygen reduction is examined using linear sweep…

Computer interfaced electrostatic charge sensors allow both qualitative and quantitative measurements of electrostatic charge but are quite sensitive to charges accumulating on modern synthetic materials. They need to be used with care so that students can correctly interpret their measurements. This paper describes the operation of the sensors,…

This handbook is based on a list of essential topics that should be mastered by the student who subsequently plans to pursue college chemistry. Chapters include: (1) "Introduction" (describing a position paper and the background of the handbook); (2) "Essential General Topics and Objectives"; (3) "Testing Students"…

The techniques used for teaching college economics have remained relatively unchanged over the past few decades. These techniques do not give the students an opportunity to apply, to develop, or to practice the economic theory they read about and hear in lectures. They tend to reinforce student assumptions about the subject's "givenness"…

This collection of articles provides an overview of some of the recent social science research projects performed by state agricultural experiment stations. The examples highlight social science's contribution to problem-solving in rural business, industry, farming, communities, government, education, and families. The following programs are…

This information booklet contains the information necessary to administer the annual Department of Defense Dependent Schools Pacific Region Junior Science and Humanities Symposium (JSHS) at the school level. It is intended to be used by teachers and administrators as they manage the JSHS program within their schools and by students as they conduct…

Designed to use simple materials that can be found in almost any household, this document provides elementary teachers and students with activities and worksheets that deal with basic scientific concepts. The activities are intended to help students form and test their own hypotheses. Each topic in the booklet is addressed through a simple…

Listed in this syllabus are concepts and understandings in four areas dealing with science, technology and society: (1) relationship of science and technology; (2) the nature of technology; (3) the interaction of science, technology, and society; and (4) making decisions about technology. Included with these concepts and understandings are…

This book is the teacher's edition to the 1987 edition of the Biological Sciences Curriculum Study Green Version textbook. It contains directions for teaching with this version, a description of the accompanying materials, teaching strategies by chapters, lists of useful software, safety guidelines, a materials list, chemical safety information,…

This study was designed to determine if the final grade in college biology at a suburban community college was a true measure of student's knowledge. One hundred and seventy undergraduates taking a semester course in biology took part in the study. This population was randomly separated into a control, placebo, and experimental group. The progress…

This analysis of the relationship between science education and technology over the past 15 years focuses on lessons learned from research on learning and instruction, the relationship between the teacher and technology, and the influence of technological advances on educational practice. Five conclusions are drawn: (1) courseware authoring…

Most children become excited about science because they can do something and because they can watch the results. These are some of the answers most elementary school students tell you when they are asked about science class. It has been substantiated by decades of research that experiential experiences are exciting and remembered, visual and…

Some researchers have argued that it is important to match teaching styles with students' learning styles, although a relatively small amount of research has been done on learning styles in science. This study focused on the differences between male and female secondary school chemistry students in an effort to determine the relationship of gender…

To investigate the effect of outside help in executing a successful science fair project, surveys were distributed to 356 participants in the 1987 Mississippi Region V Science Fair. Of this number, 147 students were in grades 7 and 8, 136 in grades 9 and 10, and 73 in grades 11 and 12. Students listed the number of hours they spent using outside…

This report includes three experiment sections. The first experiment tested sensitivity to loss in altitude and demonstrated that: (1) preview effects led to adaptation; (2) sensitivity decreased with higher flow rates; and (3) sensitivity increased with higher optical texture densities and fractional loss. The second and third experiments…
