Practical classes on protein expression and purification were given to undergraduate biology students enrolled in the elective course "Introduction to Genetic Engineering." The heterologous expression of the green fluorescent protein (GFP)* of "Aequorea victoria" is an interesting system for didactic purposes because it can be viewed easily during…

Graduate teaching assistants (TAs) are hired to assume some of the teaching duties in large general chemistry programs. They serve as liaisons between students enrolled in the course and the professor in charge. Being assigned to teach immediately on arrival at graduate school may be overwhelming to novice graduate students. When sending them into…

In order to engage their students in a core methodology of the new genomics era, an everincreasing number of faculty at primarily undergraduate institutions are gaining access to microarray technology. Their students are conducting successful microarray experiments designed to address a variety of interesting questions. A next step in these…

This report describes a laboratory exercise that was incorporated into a Cell Biology and Molecular Biology advanced course. The exercise was made for a class size with eight students and was designed to reinforce the understanding of basic molecular biology techniques. Students used the techniques of reverse transcription and arginase activity…

Metabolism, the sum of all chemical reactions within a living organism, is one of the most fundamental concepts presented in introductory microbiology courses. However, it is often difficult for instructors to effectively translate perfunctory diagrams of glycolysis, the Krebs cycle, and the electron transport chain in a way that is meaningful to…

The purpose of this study was to analyze the new Zambian high school physics syllabus and practical examinations for levels of inquiry and inquiry skills. Several inquiry skills are explicitly emphasized in the introduction, aims, content objectives and assessment sections in the national high school physics syllabus. However, the syllabus is less…

The principles, difficulties and challenges in control education are discussed and compared to the similar problems in the teaching of mathematics and systems science in general. The difficulties of today's students to appreciate the classical teaching of engineering disciplines, which are based on rigorous and scientifically sound grounds, are…

Directions are given for the construction of a manometer to measure animal metabolism. Steps in an experiment to measure frog metabolism are specified. (DT)

Discusses the educational values of participating in science fairs, and outlines the procedure used at Saint Ursula Academy, Toledo, to interest each biology student in an individual investigation. (JR)

THE SPONTANEOUS BEHAVIOR OF A TEACHER AND HOW THIS BEHAVIOR AFFECTS LEARNING IN THE CLASSROOM WERE INVESTIGATED. INDEPENDENT VARIABLES IN THE STUDY WERE DIRECT TEACHER INFLUENCE, AND THE NATURE OF THE SPECIFIC LEARNING TASK. THE DEPENDENT VARIABLES WERE THE ACTUAL MEASURES OF LEARNING, INCLUDING AWARENESS OF FACTS, APPLICATION OF PRINCIPLES TO…

Reported is a study comparing two laboratory teaching methods used with a college level general physical science course. The criterion instruments used were: (1) Watson-Glaser Critical Thinking Appraisal; (2) The Sequential Test of Educational Progress; (3) Nelson-Denny Reading Test; (4) Welch Science Process Inventory; and (5) The Smith Appraisal…

Outlines an experimental procedure in which an iodine radioisotope is used to determine molar combining ratios of lead and silver with the iodine. Tables and graphs show the definitive results that should be attainable. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

Describes an exercise which familiarizes students with organic chemistry terms and introduces preferential degradation reactions. (CP)

Short reports contributed on a variety of biology topics are presented. (CP)
