A description of how a self instructional program for introductory earth sciences was developed in the face of budget reductions. (AK)

A brief review of the instructional aids currently or soon to be in use in Finland. (LS)

Describes a two-hour laboratory course entitled "Chemical Periodicity offered first semester of the freshman year. Three cation groups, one anion group, and a final unkown salt are qualitatively analyzed. Course fosters scientific thinking in experimentation by encouraging student-initiated schemes of analyses rather than "cookbook schemes. (RR)

Describes a student laboratory project involving the design of an "acoustic suspension speaker system. The characteristics of the loudspeaker used are measured as an extension of the inertia-balance experiment. The experiment may be extended to a study of Stelmholtz resonators, coupled oscillators, electromagnetic forces, thermodynamics and…

Describes a general chemistry experiment which uses infrared spectroscopy to analyze inorganic ions and thereby serves to introduce an important instrumental method of analysis. Presents a table of eight anions and the ammonium ion with the frequencies of their normal modes, as well as the spectra of three sulfate salts. (RR)

This is an example of how author experimented in systematically using his understanding of T Group phenomena to conceptualize and to point to a sequence of phases which might be optimum for a particular group in accomplishing its learning objectives, and illustrates one technique for shifting group's focus from one issue to next.
