Describes an undergraduate organic chemistry experiment in which stilbene is cyclized to phenanthrene by irradiation for 24 hours in a photochemical reactor. (MLH)

Provides a description and evaluation of a university's recently instituted physics learning center. Photos and text reveal some uses of the facility. (Author/CP)

Describes the contents of a BIOS i Kit as: (1) guide to initial learning possibilities; (2) state of knowledge articles; (3) sample materials for observation, identification, and/or experimentation; and (4) evaluation materials. (LS)

Presents a set of integrated experiments for the undergraduate inorganic chemistry laboratory, designed with the belief that a related set of syntheses, reactions, and characterization techniques sums to a greater learning experience than an equal number of unrelated experiments. (MLH)

Describes sources and housing of laboratory rats for use in investigating behavior. (LS)

Describes the apparatus of a chemistry kit that also contains a pupil's manual and a teacher's guide. (LS)

Describes how to construct thin layer chromatography apparatus by using a sheet of glass, glass strips, epoxy resin and a chromatographic plate. (LS)

Describes an experiment demonstrating genetic transformation that opens up many areas of laboratory work and discussion with students. (LS)

Describes the insertion reaction using the insertion of carbenes into carbon-hydrogen bonds as an example. Outlines an experiment that will illustrate dihalocarbene insertions into diisopropyl ether. (GS)

Describes an activity designed to introduce concepts of randomness and standard deviation. (CP)

Examines relative effectiveness of four types of relaxation training including Jacobson-Wolpe and electromyograph (EMG) feedback. Dependent measures are EMG recordings and self-report measures of relaxation. All groups reported increased relaxation, but EMG groups were superior in EMG measures of speed of learning and depth of relaxation.…

A discussion of the centrality of the need for and a commitment to the concept of heterogeneous grouping as the basis for open educational alternatives, aimed at supporting each and every child's development by valuing his educability, potentiality, and the positive connotations of difference. (EH)

Describes the procedures in growing thymol crystals and suggests eight activities which can be carried out by students in examining crystals. (BR)
