Programmed Teaching Aids
Molecular Equilibrium
Programmed teaching aids for nse in general chemistry are becoming much more widely available. A brief description of five of these series which have appeared recently are given below. The purposes for which the programs are designed vary as do the f o r m of the program themselves. The following remarks are intended to provide an idea of the scope and level of the oroerams ~ . . as a a i d e to what ia svailnl,lr xnd not as nn evalunfion of their effwtwmcss. It is virluullg impwsihle to rvalunre eNerrivmr.es without actual use. Even then, misuse or unrealistic expectation on the part of an instructor may keep potential value from being realized. On the other hand, even what may appear to the uninitiated to he an ineffective program (assuming no inaccuracies of fact) can serve well a specific purpose clearly recognized. The obvious enthusiasm of advocates, hacked by results in their classroom certainly means that programed learning devices should be investigated.

Paperbound. $2.25. This is B linear program covering the introductory theory of equilibrium in molecular reactions from thestandpaint of forward and reverse reaction rates. It is designed to be self-contained hut can, of course, be wed as an auxiliary aid also.

atudent in areas where students traditionally have the greateat difficulties. These could not be used ea a. text by themselves. The type of program is again the linear type with answers to be filled in by the student before proceeding to the next question. Volume I includes chapters dealing with stoichiometry, electronic structure of atoms, molecular structure (from electron dot and orbital atandpoints), and ideal gas laws. Volume I1 deals with thermochemistry, eolligstive properties, acid-base neutralization, balancing redox equations, equilibrium prohlems and kinetics. Kinetic Theory of Gores. Ports 1 and 2
Jesse H. Day, Ohio University, Athens. Fearon Publiahers, Inc., San Francisco, 1963. Part 1, 27 pp.; Part 2, 44 pp. 14 X 21.5 cm. $.50 each part. These two little pamphlets are of particular interest because they use the branched program technique. The student is given a choice of several answers and, depending on the one chosen, is given information to correct the particular miaconception he has, or else sent on to the following question if he chose the right answer. Part I deals with the postulates of the kinetic theory of gases; Part I1 deals with the quantitative relations between molecular motion and gas properties. Chemical Concepts

This h e a r program is designed to clarify or teach some of the very basic concepts encountered in general chemistry courses. The various parts deal with chemical symbols and formulas, chemical equations and stoichiometry, and ideal gases. General Chemistry: A Programmed Review

This is another linear pmgram which, according to the author, is designed as a complement to a text. It appears, however, to cover subjects completely enough so that it could be used by itself. The order of coverage of material is as follows: Atoms and Molecules, Chemical Bonds, Reaction Rates, Equilibrium, Atomic Nucleus, Gases, Liquids and Solids, Solution Cbemistry, Acid-Base and Redox. These are followed by approximately 100 pages rovering the descriptive cbemistry of all the major groups in the periodic table.
