Describes problems with teaching embryology in the traditional manner. Presents a new approach where students prepare presentations, questions, and discussion topics. During laboratory periods, students conducted their own long-term research projects. (PR)

Describes a project to improve the science curricula and the science teaching skills of instructors in Houston-area two-year colleges in such a way that the program can be replicated in other locations. Two-year college faculty members were teamed with faculty from universities. (PR)

Describes the working of the Science Task Group on the place of investigation in the National Curriculum in England and Wales. (PR)

Describes relatively simple and inexpensive experiments for demonstrating the immune response to honeybee venom in the American cockroach, "Periplaneta americana." (PR)

Provides instructions for teachers and students to culture protozoans for use in science laboratories. Sections include setting up a culture area, basic culture media, amoeba culture technique, powdered milk-wheat-rice medium, alfalfa medium, and uses of the protozoa in the laboratory. (PR)

Describes a technique to isolate unsheared bacterial DNA and subject it to restriction endonuclease enzyme digestion. (MDH)

Describes an inquiry lab that helps students discover the chemical nature of enzymes. (PR)

Examines the role of practical activities in secondary science from an international perspective and contrasts this to a developing country's perspective. Discusses research studies on training teachers to include physics practical work in Indonesia and the benefits and constraints of implementing practical work in physics classrooms. Contains 37…

Describes a simple halogenation experiment that can be performed quickly in an open vessel at room temperature with visible light that is appropriate for the beginning weeks of an introductory organic chemistry course. (WRM)

Describes the transformation of PHY 101-02, an introductory physics course taught at Northern Virginia Community College, Annandale Campus, into a distance learning course by putting the lecture component on video tape and transforming the laboratory component into "at-home" labs. Course requirements may be completed on students' own…

Presents an activity that allows students to observe crawling and swimming behavior in Lumbriculus variegatus, a freshwater oligochaete worm. Contains 12 references. (WRM)

Provides a protocol for examining the mechanisms of animal thermoregulation in a straightforward but more sophisticated manner than using a thermal gradient. Describes a methodology for conducting operant conditioning to examine thermal set points for ectothermic animals. Contains 20 references. (WRM)

Describes a freshman biology laboratory project that uses the polymerase chain reaction to introduce students to the interrelationship between biology and chemistry. Students must develop their own experimental protocol, perform calculations introduced in freshman classes, and evaluate group dynamics. (Author/WRM)

Describes an experiment that extends Newton's instantaneous-impulse method of orbital analysis to a graphical method of orbit determination. Discusses the experiment's usefulness for teaching both horizontal projectile motion and instantaneous impulse. (WRM)

Describes a survey of the views of students, teachers, advisers, and inspectors on school science at key stages 3 and 4 (11-16 year-olds) in the United Kingdom. Finds a mismatch between the intended purposes of the Science National Curriculum and supporting documentation, and its translation into classroom practice. (Author/WRM)
