Describes a lab demonstration that illustrates the effect of different colors or wavelengths of visible light on plant growth and development. This demonstration is appropriate for use in college biology, botany, or plant physiology courses. (HM)

Presents an attempt to explore plant chimeras and to demonstrate the separation of genetically distinct tissue in a chimera using an easily grown scented geranium plant. (HM)

Presents three science programs developed as special topics courses at one of the two-year regional campuses of the Pennsylvania State University, Shenango Valley. The authors outline these programs in biology, physics and chemistry to illustrate their plasticity for program development and experimentation. (HM)

Discusses the problem of the protection of human subjects involved in educational research. Potential risks to which students participating in science education research may be exposed are discussed. The need for specific federal guidelines for protecting human subjects involved in science education research is suggested. (HM)

Presents some minicourses and equipment which college professors consider new in science teaching, such as: (1) the environmental educational minicourse of Virginia Polytechnic Institute and State University; and (2) multiple-choice testing without retyping. (HM)

Describes the multimedia student response system which has been used at Ball State University, Muncie, Indiana, in teaching biology. Specific guidelines followed in developing the multimedia student response software are also presented. (HM)

Presents several new products and equipment for teaching college science courses such as the electronic toploading balances and the hologramaker. A description of each product, cost, and addresses of manufacturers are also included. (HM)

Discusses how to set the ambient standards for water and air based on cost-benefit analysis. Describes marginal analysis, the basis of cost-benefit analysis and how dynamic cost-benefit analysis is carried out with application to the automobile pollution problem. (HM)

Describes the Learning Systems Approach used in a large multisection general chemistry program at Texas A&M University. The use of learning objectives, alternative learning resources, positive-attitude factors, future-oriented course content and student evaluation and performance are also included. (HM)

Indicates that the computer will become, over the next fifteen years, a revolutionary force in learning, completely transforming current processes and ways of operating. Discusses the current situation, the possibilities of developing technology, and several models of the future of education involving computers. (HM)

Describes the American contributions to scientific discovery in the first half of the nineteenth century. The article also discusses the accomplishments of three American scientists of that time: Nathaniel Bowditch, Josef Henry, and Benjamin Silliman. (HM)

Discusses the energy/environmental/economics issues that are considered urgent and long-lived. Also describes the National Science Teachers Association (NSTA) energy-educational projects and materials such as the NSTA-Energy-Environmental Materials, Energy and Education Newsletter, and the Summer 1976 and Summer 1977 instructional products. (HM)

Describes how the study of established association patterns in the form of postulational-deductive systems can engender both learning and thinking. The authors used Darwin's theory of descent with modification to illustrate some parts of the above thesis. (HM)

Investigates whether chemistry laboratory skills are commonly developed in secondary schools and whether college professors and high school teachers agree that students still demonstrate these skills in first-term college chemistry labs. One hundred and four chemistry teachers and 298 college professors participated in this study. (HM)

Presents a simulation model approach to the study of evolution. This model combines both practical and theoretical aspects of evolutionary biology course work. The author has used laboratory hardware for this simulation with 20 working groups of students. (HM)
