Describes a factorial experiment that is used as a laboratory exercise in a research methods course. Uses a Howard-Dolman depth perception apparatus, combining the factors of viewing condition and rod orientation to illustrate the nature of an interaction and the necessity of an additional analysis of simple main effects. (Author/LS)

Introduces programs that assist blind students such as Tactile Access to Education for Visually Impaired Students (TAEVIS). Reports on two blind students who successfully completed physics courses and their learning strategies. Discusses the accessibility of visual aids. (YDS)

Describes laboratory techniques designed to familiarize students with meiosis and how microscopic preparations of meiosis are made. These techniques require the use of fresh or fixed flowers. Contains 18 references. (DDR)

Describes a procedure based on the assumption that during the rated lifetime of a light bulb roughly half of the radius of the filament evaporates. Explains how the filament's operating temperature can be deduced. (DDR)

Provides descriptions of a range of resources and methods that can be used to produce metals such as titanium, vanadium, chromium, manganese, iron, and molybdenum. Details on equipment and safety precautions are also outlined. (DDR)

Explains a series of experiments that enable students to discover the internal and external structure of the vanilla pod, isolate the chemical constituents of the pod, identify vanillin in the pod extract, and compare extracts across varieties of vanilla. (DDR)

Describes how a jigsaw cooperative learning structure divides lab work in a constructive, efficient way and provides a mechanism for sharing information. Pre-lab lectures are replaced with focused student discussions about the lab exercises. Students become more involved with the lab exercises, take responsibility for their own learning, and are…

Hampshire College needed to create opportunities for advanced undergraduates to have extensive laboratory or field experience in experimental sciences. A general biochemistry course, taught almost entirely in the laboratory, is described. The focus of the course is enzymes as catalysts and as proteins. (MLW)

Reviews a study that examined the effects of laboratories on the grade performance of undergraduates in an introductory crop science course. Results indicated that students enrolled in lecture and laboratory concurrently did not receive higher lecture grades than students enrolled solely in lecture, but did have higher laboratory grades. (ML)

Argues that many laboratory experiments are designed to be clever and challenging but instead are confusing and frustrating for most students. Describes the use of a teaching approach in English courses for chemistry laboratories in which students get to do the experiment for fun and practice, then meet with the teacher for discussion before…

Describes the use of simple projects to help freshmen-level chemistry students develop chemical knowledge and an aptitude for the research process. These projects pose a new problem to students without presenting a detailed experimental procedure. Guiding questions help students design their own experiments and stimulate students to think…

Describes study conducted at the University Sains Malaysia with pharmacy students that compared a videotaped demonstration with a conventional laboratory experiment in physiology to determine the short-term and long-term effectiveness of the instructional media. Treatment for the experimental and control groups are described, and results are…
