Reports on many news items of importance to the scientist and educator. These include a new Engineering degree, building a biological culture analyser, remote satellite sensing in geologic exploration, and others. (GS)

Reports on an investigation of self-pacing in an undergraduate personality course taught by the Keller method. Results indicate that grade point average is related to rate of progress, but that even the weaker students can achieve mastery. (GS)

Describes an approach to evaluation in which students were given a second chance to demonstrate knowledge of the subject. Areas investigated include student willingness to retake the examination, the effect of the retake on student scores and class distribution, and the relationship between initial performance and retake score. (GS)

Describes a series of demonstrations and/or group activities used in a science methods course for prospective elementary school teachers. The topics include center of gravity, behavior of fluids; electricity and magnetism, the motion of objects, chemical reactions, and sound. (GS)

Describes the use of a programmable calculator for student experiments, grading of laboratory reports, and assigning accuracy and precision scores. (GS)

Traces the history of National Science Foundation curriculum implementation efforts. Outlines recommendations of the Moudy Committee for future development and implementation procedures. Man-a course of Study (MACOS) is given particular attention. Discusses the probable effects of the majority report. (GS)

Cites evidence that indicates if a lecturer pauses at least three times during a lecture for two minutes and has students compare notes, student retention of the lecture material will be increased. Explains another form of pausing called wait-time employed in discussion situations. (GS)

Presents the reinforcement theory of learning and explains how it relates to the Keller Plan of instruction. Advocates the use of the Keller Plan as an alternative to the lecture-demonstration system and provides an annotated bibliography of pertinent material. (GS)

Describes efforts by Central Washington State College to take courses and programs to the community thus negating the student on-campus residence requirement. Illustrates the effect of this effort by listing the enrollment figures for some science courses taught off campus. (GS)

Describes an instructional approach in which students submit topics of interest. The study of these topics begins with a student report followed by questions and discussion with the instructor developing the major concepts. (GS)

Describes a science seminar program designed for a small science department in a two-year college. Presents a list of topics covered. (GS)

Describes the Open University concept which is designed to provide regular college credit through a program of home study. Explains three science-related Open University courses and lists and describes the films and cassettes used. (GS)

Listed are a number of materials including a spectrophotometer, power meter, vacuum pump, fume hood, cart system, and others. The source of the product and a brief description are given for each. (RH)
