Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Explains how Darwin's observations and experiments can be used to show the true nature of science and good scientific methods. (PR)

Describes experiments by Thomas A. Knight on geotropism. These experiments took place about 200 years ago and used a centrifuge. (PR)

Describes using the aquatic plant, duckweed, for open-ended investigations and learning about factors important in photosynthesis. (PR)

Outlines the stages of a cell biology "pulse-chase" experiment in which the students apply autoradiography techniques to learn about the concept of the cell cycle. Includes (1) seed germination and plant growth; (2) radioactive labeling and fixation of root tips; (3) feulgen staining of root tips; (4) preparation of autoradiograms; and…

Describes using the common house plant, "Coleus blumei," to illustrate gravitropic effects, phototrophic effects, and hormonal effects in plants. (PR)

The life history of the Chironomus tentans can be observed in easily established and maintained laboratory cultures. Projects for the classroom include observing hydration of an egg mass; embryonic development, hatching and larval feeding; larval activity; and mating activity. (MDH)

Explains how tradebooks can be used in science instruction. Presents lists of tradebooks for teacher use to (1) lower abstraction, (2) develop skills and talents, (3) enhance self-esteem and social skills, and (4) measure mastery through alternative assessment activities. Also presents lists of tradebooks for student use. (PR)

Describes the statistical test of chi-square analysis. Explains how this test can be used in biology instruction. Examples from blood typing are used. (PR)

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

As science teachers, they understand the importance of gaining student interest to promote learning. They know how challenging it is to spark the curiosity to truly engage students in the processes of "doing science." One often-used method of motivation is the demonstration of science in action. Demonstrations such as "discrepant events". They are…

This manual is intended as a resource for teachers who have special education students in their mainstream science classes, for curriculum adoption committees, and for publishers and consumers of science curriculum materials. Part 1 describes general characteristics of students with disabilities and provides general mainstreaming strategies and…

Science process skills such as observing, classifying, inferring, interpreting, predicting, and hypothesizing can all be classified as a sub category of thinking skills. This book is part of the series "Strategies for Learning" that focuses on the step-by-step development and application of thinking skills as a vehicle for learning science. The…

This document series has been established as part of Unesco's Science and Technology Programme to encourage an international exchange of ideas and information in science education. This volume addresses the improvement of biotechnology education in school up to year 10 and aims at improving the quantity and quality of biotechnology taught in…

This document is written to encourage college faculty to use a student-centered, activity-related, approach to science instruction. Suggestions are provided for methods that can be used by faculty and administrators to develop alternatives to lecturing. The major sections of this document include the following: (1) Is There an Alternative to…
