Variability in the grammatical profile of finite verbs in English is examined in 20 Master of Science theses in biology, chemistry, and physics. The use of verbs with respect to voice, tense, aspect, and modality is examined in five rhetorical sections of the theses--introduction, review, methods, results, discussion. (SED)

Describes a video monitoring technique for detailed analysis of student use of computer-based learning programs which produces a synchronized record of computer output and student use; a study concerned with developing computer-based learning programs in chemistry which utilizes the technique; and advantages and disadvantages of the technique.…

Reports on a project in which observations of student and teaching assistant behavior were used to redesign a teaching unit on recrystallization. Comments on the instruction manual, starting points for teaching the unit, and list of objectives with related tasks are included. (JN)

Twelve papers focusing on various aspects of teaching chemistry to the nonchemist are presented. Includes details of courses designed around specific topics and/or needs (such as art hazards), use of field trips, issues related to the problem of explaining technical ideas to lay persons, and other topic areas. (JN)

Identifies assumptions and points out specific design questions which can help guide the development of successful programs to assist nontraditional students. Lists five myths identified as interfering with program development. Also reviews some factors to be considered in evaluating an assistance program and provides a concluding analysis. (JM)

Recommends using dramatic demonstrations on the energy in chemical systems as an audiovisual adjunct to lectures and laboratory sessions. Lists materials needed and provides procedures including safety tips for various experiments to produce chemical light, heat, and electricity; and concludes with hints for preparation/rehearsal. (JM)

Provides innovative ideas in biology, chemistry, and physics on the following topics: enzyme decomposition; chemical waste; time measurement; acid-base color magic; ball bouncing properties; heat; cell theory; and specimen boxes. Materials and procedures are listed when appropriate along with hints for expanding these ideas and investigations. (JM)

Presents seven papers on computer applications in chemical education. Topics include current status and future of teaching with microcomputers, improving undergraduate experiments with online microcomputers, chemistry's mathematical models with computer simulations, computer uses in freshmen chemistry (tutorial-drill programs, laboratory…

Background information, procedures, and typical results are provided for a three-part experiment involving reactions of potassium thiocynate (KNCS) with sulfuric acid. The experiment represents the final stage of structured work prior to students' research projects during their final year. (JM)

Discussion of science education in general and the possible role of microcomputers is followed by an evaluation of four software packages for seventh grade through college level. These packages are in the areas of genetics, prelab studies for chemistry, a science education game, and experiments in human physiology. (MBR)

Describes an audiovisual teaching unit on the chemical laboratory technique of recrystallization which was developed along problem-solving lines and based on observation of student laboratory behavior. Discussion includes usual procedures for developing such units, how this unit solves problems typically associated with teaching, and its general…

Provides (in table format) lists of chemistry prerequisites in biology textbooks, physics prerequisites in chemistry textbooks, chemistry prerequisites in physics textbooks, and mathematical requirements of physics and chemistry. Indicates that mathematical requirements for chemistry and physics are similar and that substantial chemistry and…

Examines the present state and future of high school chemistry, and whether a crisis exists in chemistry at the high school level. Also proposes a new model for chemistry education and suggests that new materials and sufficient training and retraining are needed to implement new ideas and instructional strategies. (JN)

Alternatives to traditional, large-class lecturing are discussed. They include using canned lectures, demonstrations and lecture experiments, computer simulations, problem-solving strategies, breaks during lectures, and movies. Moving out of large classrooms to laboratories and resource rooms (or giving an examination) is also suggested. (JN)

Describes the evaluation and revision of the O-level Nuffield chemistry student and teacher curriculum materials. Includes a discussion of the rationale for the evaluation process and the methodology used. (JN)
