Discusses the use of direct demonstration of the connections among the science process skills and the content areas of science. (MKR)

Describes two laboratory exercises corresponding to studies of statics and dynamics to illustrate the concept that the combination of real and simulated laboratory tools, with some real data being recorded in computer-aided form, can result in a very sound understanding of physical principles. (JRH)

Ecological, interdisciplinary, and interconnected laboratory lessons focusing on magneticism: (1) producing electric power; (2) magnetics and magneticism; (3) electomagnetism (2 parts); and turbines (2 parts). Lessons, designed as precursor for students to make choices in electricity production, use a directed inquiry approach. (MCO)

A technique for studying various properties of soap bubbles subjected to deformation, accompanied by some representative experiments to illustrate the versatility of the method, is presented. The measurement of the change of force that occurs when a bubble is stretched is calculated. (KR)

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)

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)

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)

Compares the academic performance of students exposed to either "wet" practical classes or "simulated" practicals. Assessed practical write-ups from pharmacology students using a simulation showed a mark significantly better than those doing the "wet" practical. Simulations can provide an aid to learning which is as effective as "wet" practicals,…

The intent of this study was to investigate the impact of introducing computerized means, mainly simulation and the Internet, on teaching and learning electronics in Israeli high schools. Computers in electronics studies are, at the same time, part of the subject matter learned and a means for teaching and learning. Data were collected through…

Although much contemporary thinking leads to the expectation that communication technology, such as video streaming, enhances educational performance on the average, a dearth of strong evidence consistent or inconsistent with this claim precludes a thoughtful evaluation of it. A series of experiments designed to examine this proposition…

Imagine a science activity that excites native English speakers and English learners alike while simultaneously teaching students about tools used in science experiments, increasing science vocabulary, and improving students' skills in recording information. Inventorying science kits or materials from science units with students does just that…
