Discusses the use of a central computer linked to a CRT console, with display projected onto a large screen, to operate computer augmentation of lectures in large group instruction. Indicates that both introductory tutorial and computer modes are feasible in subject matter presentation. (CC)

Discusses the use of the "extent of reaction" in teaching freshman honors classes of elementary chemistry to provide students with a unifying concept in the treatment of stoichiometry. Four sample problems are included. (CC)

Discusses the case of DDT which can be introduced to nonscience students in a chemistry course, including the development of DDT, problems associated with its adverse effects, and curtailment of its use in our environments. (CC)

Presents a brief description of six new tests released by the 1974 testing program and condensed norms for six others published during the 1971-73 period. Included is a list of tests featured in this year. (CC)

Describes the present status of science as an industrialized-affluent culture resting upon a public woefully lacking in scientific background and scientists with activities taken in by nihilism. Suggests all scientists actively work together through teaching, talk, and behavior to counter the forces of anti-science and nihilism. (CC)

Discusses the author's own experience with learning, teaching, and research study in chemistry. Indicates that one should take his working experience as a learning process to alleviate the reactive character of his earlier strongly held views. (CC)

Discusses the development of new curriculum materials for use in the preparation of chemical technicians in two-year community colleges and technical institutes. Indicates that the texts developed are equally suitable for the chemical part of environmental programs and medical and engineering technician curricula. (CC)
