Describes several experiments, suitable for secondary school biology classes, using the bioluminescent marine bacterium, Achromobacter fischeri. (JR)

The Suvag Lingua is a machine used to facilitate better aural perception by working from a student's error in producing a particular sound and adapting the model which is to be imitated. (DD)

Discusses the development of a one-year laboratory course in an effort to provide a link between traditional laboratories devoted to a single area of chemistry and the total involvement of a single narrow research project. Included are outlines of 32-hour lectures and 11 experiments performed in the integrated course. (CC)

Describes demonstrations suitable for secondary school biology classes relating to the effects of the hormone IAA on plant growth. Demonstrations illustrate how hormone treatments affect stem elongation, callus formation, inhibition of axillary buds, stimulation of secondary growth and initiation of adventitious root development, root elongation,…

The main purpose of the project described in this article was to give young people an opportunity to live out and identify with an adult role, that of a teacher in a primary school being taken as one example. (Author)

The basic question of the research reported here was whether or not expectancy, as defined here, was a significant factor in relationship to dissonant teacher support characteristics in affecting performance on given assignments. (Author)

Describes the construction and operational procedures of a simple setup which enables undergraduate students to conduct experiments on critical phenomena in gases. Indicates that the experimental features are proved comparable to those of the Reamer and Sage apparatus. (CC)
