Discusses the origins of such chemical terms as substance, element, analysis, synthesis, compounds, mixture, organic,'' affinity, oxidation, reduction, acid, base, and salt for the purpose of providing a background to facilitate student's understanding of chemical terminology. (CC)

Discusses formation of chemical molecules via Mobius strip intermediates, and concludes that many special physics-chemical properties of the fully closed circular form (1) of polyoma DNA are explainable by this topological feature. (CC)

Discusses experience of teaching chemistry to underprepared students whose characteristics are analyzed in great detail. Concludes that the same principles are applicable to mathematics or other science fields. (CC)

Presents the characteristics of an experimental course offered at the University of Texas in the Fall of 1971. Confirms the concept that computer-based instructional techniques have the potential of increasing both the degree and rate of student learning. (CC)

Discusses educational programs carried out by a minimum system which consists of a PDP-8/L computer with 4K memory and an ASR-33 teletype. Indicates that an entire curriculum with 450 students can be handled by simply adding some components. (CC)
