Suggests problem solving to replace lecture on a broad scale to facilitate training in intellectual skills and abilities, and in the teaching of some important facts, ideas, and concepts. (GS)

A series of well-defined steps is given for solving titrimetric problems, based on the mole concept. An example is given, including calculations from the first step to the last. (SA)

Discusses the use of a new approach, rather than quantum mechanics, to obtain practical solutions to bond energy problems. Indicates that the complex nature of mathematics and the small magnitude of bond energies involved in an approximation are two practical impossibilities for quantum mechanics to reach simple, reliable results.
