Discusses the use of small-group inquiry techniques and discovery exercises within the traditional lecture setting to teach chemistry to large nonscience classes. Included are descriptions of classroom activities, student assignments, and program effectiveness. (CC)

Summarizes the historical development of lasers, involving basic concepts in physics, applied technology, advanced experimental techniques, and human interactions. Indicates that the potential for invention of the laser had been with us at least 30 years before the event actually occurred. (CC)

Discusses the use of "generation tables" to demonstrate the effect of age on the size of a population in a biology course for nonscience majors. Included are specified assumptions and conditions for table construction. (CC)

Discusses a model for the collinear collision of an atom with a diatomic molecule on a simple potential surface. Indicates that the model can provide a framework for thinking about molecular collisions and reveal many factors which affect the dynamics of reactive and inelastic collisions. (CC)

The traditional Philippines college curriculum in nutrition is examined and a curriculum aimed at community nutrition is described. (DT)

Describes current experiments that help to explain chemical processes which probably existed prior to the first living cells. Some experiments suggest that a significant portion of a major metabolic pathway, the Krebs cycle, may have developed in the earth's primitive atmosphere to be later incorporated into living organisms. (JR)

Describes the main features of the personalized system of instruction (PSI) or Keller Plan, and outlines the advantages and disadvantages encountered in implementing this instructional format in a freshman non-major biology course. (JR)

Addresses engineering educators on the nature of motivation, how it operates, and how motivation is acquired and modified. (JR)

addresses the topic of managing motivation in Keller's Personalized System of Instruction (PSI). Outlines the reinforcing features that are at the foundation of PSI theory, and examines methods used to ensure that these reinforcing properties are fu lly utilized. (JR)

Outlines the proteinoid theory of the origin of life and examines competing or alternative concepts in the light of a sequential experimental model. (JR)

Discusses the general design and operation of a quantitative analysis laboratory which is relevant to the student's career objectives and provides reliable and objective criteria for judging student performance. Included are a list of core experiments and a description of student responses. (CC)

Discusses experience in teaching chemistry to nonscience students, including teaching objectives, topic selection, and student interest in environmental problems. Indicates that important attitudes toward nature, science, and technology can be taught to the students through the use of nonscience major courses. (CC)
