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…

I describe and evaluate SuperLab LT (Chase & Abboud, 1990), a software package that enables students to replicate classic experiments in cognitive psychology. I also discuss the package with respect to its uses in teaching an undergraduate course in Experimental Psychology. Although the package has minor flaws, SuperLab LT provides numerous…

Investigates the effects of interactive computer-based simulations presented prior to inquiry-based laboratory experiments on students' conceptual understanding of mechanics, waves/optics, and thermal physics. Uses conceptual tests to assess conceptual understandings of each topic. Indicates that the use of the simulations improved students'…

The present paper describes an educational experiment dealing with teaching the theory of formal languages and automata as well as their application concepts. It presents a practical application of an educational experiment and initial results based on comparative instruction of two samples of students (n = 56). The application concept should…

The purpose of this study is to first develop an 8-week college teaching module based on root competition literature. The split-root technique is adapted for the teaching laboratory, and the Sugar Ann English pea (Pisum sativum var. Sugar Ann English) is selected as the species of interest prior to designing experiments, either original or…
