Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Examines a solubility laboratory experiment using silver acetate and spectrophotometers for an Advanced Placement chemistry course. Covers experimental procedure, analysis of saturated solutions, and a discussion of chemistry involved. Includes an absorbance curve for silver ions and solution preparation suggestions. (ML)

Describes some adaptations made in a university physics laboratory course to accommodate a student with total visual impairment. (WRM)

Studying "Caenorhabditis elegans" ("C. elegans") live cultures provides excellent opportunities for authentic inquiry in a high school anatomy and physiology or other biology lab course. Using a digital dissection microscope, a student can photograph the organism during various stages of development and study and analyze the images. In this…

Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back to the early portions of the 20th…

The National Institute of Child Health and Human Development (NICHD) Study of Early Child Care is an ongoing, prospective, 3-year longitudinal study of over 1,300 full-term healthy infants and families from 10 sites across the United States. While the sample is not nationally representative, the subjects come from major regions of the country: the…

The connection between high school chemistry pedagogical experiences and introductory college chemistry performance has been a topic researched in published science education literature since the 1920s. However, analysis techniques have limited the generalizability of these results. This review discusses the findings of a large-scale,…

This course in mechanical devices and systems is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary technical institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in…

This course in fluid power systems is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary technical institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in company-sponsored…

This course in electronic devices and systems is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary technical institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in…

GROUP FUNCTIONING AND ACTIVITIES WERE STUDIED IN TWO CONTEXTS, THE LABORATORY AND THE REGULAR SCHOOL CLASSROOM. THE LABORATORY STUDY INVOLVED SMALL GROUP PROBLEM-SOLVING IN ARITHMETIC AND IN SOCIAL STUDIES. STUDIES CONSISTED OF GROUP PERFORMANCE, THE RELATIONSHIP OF THE HIGH ABILITY STUDENTS TO GROUP PERFORMANCE, THE RELATIVE IMPORTANCE OF…

Behavior in organizations was conceptualized to be based on self-perceived power and perceived organizational climate. Power and climate perceptions were investigated as a function of three dimensions of organizational environment. The 2 x 2 x 3 (level of participation, profit or service orientation, and position level, respectively) design (N =…

Describes four physics experiments including "Investigation of Box Resonances Using a Micro"; "A Direct Reading Wattmeter, DC or AC"; "Exercises in the Application of Ohm's Law"; and "Hysteresis on Gas Discharges." Discusses procedures, instrumentation, and analysis in each example. (CW)

Presents an approach for building an inexpensive control engineering laboratory to support control courses in an undergraduate engineering program. Outlines the use of simple amplifier circuits and small personal computers in performing control experiments. Proposes an optimum configuration of the laboratory for minimum servicing and adequate…
