Described are the apparatus and procedures needed for a demonstration of the measurement of the electrical resistance of metals as a function of temperature using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

Described are the apparatus and procedures needed for a demonstration of a determination of the polarity of charges carried by individual ground flashes of lightning. Discussed are materials, apparatus construction, and experimental results. (CW)

Described are the apparatus and procedures needed for this correction technique using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

Suggested is a methodology for teaching and assessing group problem-solving with secondary school pupils. The results of a study conducted on this method are presented. The problem-solving approach used and operational definitions for assessment are listed. Scenarios for problem-solving activities are included. (CW)

Described are the camps, competitions, and tests of the U.S. National Chemistry Olympiad. International competition, local exams, participating high schools, and national exams are highlighted. A summary of test results from the 1988 national examinations are presented. (CW)

Presented are reviews of two computer software packages for Apple II computers; "Organic Spectroscopy," and "Videodisc Display Program" for use with "The Periodic Table Videodisc." A sample spectrograph from "Organic Spectroscopy" is included. (CW)

Discusses a microcomputer-based laboratory (MBL) study (n=75) which uses multiple temperature gathering devices (mercury thermometer, digital thermometer, and computer probe) and graphing methods (hand graphs, delayed computer graphs, and real-time graphs). Reports that MBL real-time graphing provides significant increases in graphing skills. (MVL)

Discusses a two-year masters program; one year of lecture and practical training, and a second year on a supervised design task in an industry or development laboratory. Reviews the emphases of the curriculum. Describes the two paths to engineering careers in the Netherlands. (MVL)

Described is a program for two-week, tuition-free courses offered twice a year dealing radiation and radioactivity. Laboratory exercises, tours, schedules, enrollment and accreditation, and staffing are discussed. (CW)

Discussed are the advantages and processes of making collections with children. An activity for making a classroom collection (herbarium folios) is described and includes materials and procedures. The processes of collecting and classifying are stressed. (CW)

Describes a science experiment in which the heartbeats of mammals can be counted and graphed as measurable data by the computer. Provides information on materials needed, pre-lab activity worksheet, and follow-up activities. (RT)

Describes the Assessment of Performance Unit (APU) Science project. Discusses the findings including perceptions of problems, procedural understanding, control of variables, and measurement strategies. Suggests a change from traditional learning strategies to more student-centered ones. (YP)

After brief histories of laboratory schools and comparable Japanese "attached schools," this article promotes preservation of university-controlled schools in a cooperating schools network that provides teacher training and experimentation sites. Although university-controlled schools may have professional development school…

Describes and illustrates a technique for using guided dramatization in intervention with special needs or at-risk children. Discusses social benefits of the technique. Maintains that the technique is useful for helping mainstreamed children socially integrate into the regular classroom. (BG)
