Summarizes data gathered from questionnaires sent to teacher education institutions and all 50 state departments of education regarding environmental education in the United States from 1970-76. Conclusions tend to support a continual rise in environmental education activity, with a peaking in 1975 and a decline in 1976. (CS)

Describes a study focusing on student self-assessment and self-grading of examinations that test higher-order cognitive skills. The study supposed that by evaluating their own performance, students could not only enhance academic strengths and reduce weaknesses but also learn material in greater depth and further develop critical thinking skills.…

Describes evaluations of CAL (computer-assisted learning) at the Open University (Great Britain). Highlights include evaluation of science teaching; evaluation of the Home Computing Policy; CAL evaluation in the literature; and a framework for a principled approach to evaluation, including interactions with software, outcomes, and a case study.…

A study at the University of Transkei (South Africa), a historically black university, examined whether student efforts to work through class assignments promoted academic achievement. Results showed that of 65 subjects, those who completed the assignments regularly were the highest performers. The latter group generally failed in tests but showed…

Describes a study of 32 University of Transkei (South Africa) freshmen's conceptualization of "limiting reagent," a basic concept in chemistry, based on student responses to two written test questions and clinical interviews. Results indicated that a high percentage of students had misconceptions and could not apply the concept…

Discussion of academic library instruction focuses on helping users learn online resources. Topics include science instruction; integrating short, subject-specific online instruction into the classroom; virtual tours; long-term approaches; integrating online modules into undergraduate courses; corporate librarians' efforts; and vendors' Web-based…

Described are engineering programs that have used automated data acquisition systems to implement data collection and analyze experiments. Applications include a biochemical engineering laboratory, heat transfer performance, engineering materials testing, mechanical system reliability, statistical control laboratory, thermo-fluid laboratory, and a…

Discussed are the properties, chemistry, generation of precursors, and use in organic synthesis of this isotope of carbon. The use of carbon-11 in research is emphasized. Pitfalls and possibilities are described. (CW)

Described is a simple circuit with which students can observe the effect of common dielectric materials in a capacitor and measure the dielectric constant of a piece of paper. Discussed are the theory, apparatus construction, and experimental procedures for this activity. (CW)

Directions for the construction of this apparatus are presented. Materials and procedures for its use are discussed. The behavior of particles in the apparatus is described. (CW)

Four applications of microcomputers in the chemical laboratory are presented. Included are "Mass Spectrometer Interface with an Apple II Computer,""Interfacing the Spectronic 20 to a Computer,""A pH-Monitoring and Control System for Teaching Laboratories," and "A Computer-Aided Optical Melting Point Device." Software, instrumentation, and uses are…

Presented are nine physics demonstrations. Topics include mechanics, magnetism, mass, optics, friction, and molecular motion. An illustration and questions are included for each. (CW)

Described is a laboratory interface system including hardware, software, and student activities. Student use of this system is reviewed stressing experimental design skills and student-designed experiments. (CW)

The purpose of "Project Catalyst" is to enhance teacher competencies through academic-year workshops and two content-intensive summer institutes. The goals, eligibility and recruitment, selection criteria, format, and preliminary evaluation for the program are discussed. (CW)

Described is the use of Thematic Mapper images in undergraduate geology instruction. The work of the Andes Project at Cornell University is discussed. Digitally enhanced illustrations of landforms in the Andes mountains of South America are provided. (CW)
