A laboratory experiment is described which presents some molecular parameters of iodine molecule by studying iodine spectrum. Points out this experiment can be conducted by sixth form students in high school laboratories. (PS)

Presents a teaching unit on the Langmuir absorption isotherm suitable for advanced secondary school chemistry classes. Describes the experimental investigation of the isothermal adsorption of sulfur dioxide on charcoal, and discusses the derivation of the Langmuir equation and some applications. (JR)

Includes eleven topics relating to laboratory activities, experimental procedures, and teaching materials suitable for secondary school chemistry classes. (JR)

Brief description of lectures presented in a conference on Nuffield project with emphasis on chemistry teaching. There is a need for the philosophy of the Nuffield project at the college level. Less emphasis should be placed on factual information in chemistry at college level. (PS)

Describes the development of a unit on alcohols for high school chemistry students. Learning activities were heavily based on previous experiences. (PS)

Twelve new chemistry expermiments are described. Broad areas covered include atomic structure, solubility, gaseous diffusion, endothermic reactions, alcohols, equilibrium, atomic volumes, and some improvised apparatus. (PS)

Reports an investigation to determine whether or not interaction analysis could be used as a tool to analyze laboratory instruction and to identify patterns of instruction which differentiate effective and ineffective teaching. Indicates student performance can be enhanced by a student-centered climate. (Author/TS)

Discussed are individual report presentations in seminars and programed instruction as two approaches to teaching in colleges. Enthusiasts of these two methods overlook inherent demerits. Influences of a teacher's personality and interest in subject on the students should be carefully considered. (PS)

The American Chemical Society has proposed a federal program which would enable 1500 unemployed chemists and chemical engineers possessing master's or higher degrees to serve from one to two years as interns in industrial research and development installations. (Author/TS)
