Reported are two papers which deal with the fundamentals of display hardware and software in computer systems. The first report presents the basic principles of display hardware in terms of image generation from buffers presumed to be loaded and controlled by a digital computer. The concepts surrounding the electrostatic tube, the electromagnetic…

The Statistical Concepts Package (STAT-CONCEPT) is a coordinated collection of interactive computer programs and printed materials designed to enrich graduate instruction in educational statistics. Probability, descriptive statistics, sampling distributions, and power are four of the thirteen topics included. By doing the computational labor and…

This document contains instruments used in the yearly evaluations of the Laboratory for Educational Research (LER) of the University of Colorado between 1966 and 1970. It also includes the instruments used for the summer 1973 LER Summative Evaluation. The purpose of the evaluation was to determine the effectiveness of this research training…

The report presents a detailed description of the structure, capabilities, and current research activities of virtually all Federal Government R and D Laboratories engaged in environmental studies. Information shown for each of the approximately 170 laboratories includes: name, agency, location, mailing address and telephone number, director, type…

The report concludes an inventory listing of the structure, capabilities, and current research facilities of virtually all Federal Government R and D laboratories engaged in environmental studies. The inventory from DOD/USA through DOT/USCG is presented. Volume I is SE 015 598. (Author/RH)

This paper proposes a technique for using the digital computer in science instruction (grades 1-12) which may well obviate the constraints of unreasonable cost and demand for complex and extensive software. Computer Simulated Experiments require a short amount of time at the terminal during which the student collects realistic simulated data.…

Three articles in this newsletter describe investigative laboratory programs; two in marine or coastal biology (Hopkins Marine Station and the Bahamas field station of Earlham College), and the other a botany course at Colorado College. In all cases undergraduate students are expected to plan and conduct biological research, after being presented…

This paper describes a laboratory experiment which was a replication and extension of an earlier study, both of which are part of an effort to synthesize the findings of two somewhat different approaches to the study of interpersonal attraction. The first of these approaches is a secondary reinforcement interpretation and in general assumes a…

Observations and experiments with mice, developed and tested at the Pennsylvania Advancement School with underachieving boys in grades seven and eight, are described in this teachers' guide which includes copies of student worksheets for exercises needing them. In addition to lists of materials and procedural suggestions, ideas for guiding…

The relative effectiveness of "content-centered" and "process-centered" biology laboratory courses in a freshman general biology course was investigated by administering the Nelson Biology Test, Science Attitude Scale, EPS II (a problem solving test), and an Interest Inventory at the beginning and end of the one quarter course. Course examination…

Eleven tutorial-drill and four experiment-simulation computer assisted instruction (CAI) modules were designed and programmed for use on an IBM 1500 system. The modules were designed as supplementary study aids for an introductory chemistry course and were intended to assist students' achievement of specified behavioral objectives. After trial…

A lead article, Instructional Uses of School Political Experiences, written by Judith A. Gillespie, describes the High School Political Science Curriculum Project, the materials for which are in the early developmental stages. As has been explained in SO 005 407 and SO 005 409, the approach utilizes the school as a political laboratory. An effort…

Included is a list of laboratory instruments and equipment and the names and addresses of their manufacturers. Names of instruments appear in alphabetical order in heavy black type and the names of manufacturers of each instrument appear below each instrument entry in ordinary type. Each instrument is identified by a "category number." Unnumbered…

The purpose of this study was to investigate the effectiveness of a laboratory in the teaching of mathematics. A sample of 980 students in 36 seventh-grade mathematics classes from six District of Columbia inner-city schools was administered the Comprehensive Test of Basic Skills in October and in the following May. Twelve classes attended…

The annotated illustrations of biological specimens useful for illustrating the "tropical" topics dealt with in African secondary school biology courses are designed to serve a two-fold purpose. The diagrams are intended to show the pupil the structures he should be looking for in his laboratory work, with the textual material being an…
