Using meta-analysis, randomized experiments in education that either clearly did or clearly did not experience student attrition were examined for the baseline comparability of groups. Results from 35 studies suggested that after attrition, the observed measures of baseline comparability of groups did not differ more than would be expected given…

Cyclic voltammetry experiments on [60]fullerene, (C[subscript 60]), and (dihapto-[60]fullerene) pentacarbonyl tungsten(0), ([eta][superscript 2]-C[subscript 60])W(CO)[subscript 5], constitute an educational experiment for the inorganic chemistry laboratory with a primary objective to teach the chemical interpretation of a voltammogram, in…

The authors investigated how 3- and 4-year-old children and adults use relative distance to judge nearbyness. Participants judged whether several blocks were by a landmark. The absolute and relative distance of the blocks from the landmark varied. In Experiment 1, judgments of nearbyness decreased as the distance from the landmark increased, …

Graphic design's messages can reach across streets and across the globe; they can bring together countries, communities and strangers for a common cause; they can also serve to divide otherwise amenable neighbors. Design students must fully understand this potential reach and thus the responsibility they have to create tolerant, informed messages.…

Virtual worlds have been linked with e-learning applications to create virtual learning environments (VLEs) for the past decade. However, while they can support many educational activities that extend both traditional on-campus teaching and distance learning, they are used primarily for learning content generated and managed by instructors. With…

The effects of relaxation exercises on orthography performance in language arts education of fifth to seventh graders were experimentally tested. Participants were 399 basic secondary school students and their language arts teachers from the Hauptschule, a German type of secondary education covering grades five to nine that leads to a basic…

The present study examined the merits of different methods of introducing rehearsal techniques. (Author)

Discusses experiments testing the adequacy of the common attribute-value representation for knowledge about concepts. (AM)

THE NOVA HIGH SCHOOL IS AN EDUCATIONAL EXPERIMENT TO MAKE LEARNING AND ACHIEVEMENT INTERESTING, CHALLENGING, AND EXCITING TO THE STUDENT. THE PROGRAM IS BASED ON THE CONCEPT OF INDIVIDUAL PROGRESS WITH EMPHASIS ON QUALITY EDUCATION. FEATURES OF THE SCHOOL ENVIRONMENT INCLUDE AIR-CONDITIONING, CARPETING, MULTIPURPOSE CLASSROOMS, INDIVIDUAL STUDY…

An experiment was conducted to determine the effects of four information-format variables--instructions for processing information, number of documents, masking of information, and interview information--on the teacher selection decision process. It was hypothesized that the variables affect decisions by modifying the consistency of the decisions…

Experiments were devised to determine teacher effectiveness on the basis of ability to communicate, on the assumption that no relevant learning will occur if communication is faulty. A series of communication games involved an encoder (teacher) and decoder (student) to provide tentative answers to the questions: 1) Are there individual differences…

The effectiveness of four methods of speech instruction with third and fourth grade culturally deprived boys and girls was compared. The methods of instruction varied in regard to the manner in which they were developed and in sophistication from simple instructions on the operation of audiovisual equipment and materials to a commercially…

The basic problem of this study was to develop a method for increasing the efficiency of the instructional process at the introductory level. The experiment compared two methods for doing the outside of class assignments in support of a course in library science instruction. The plan called for the control groups to do the outside assignments in…

This speech discusses the planning for and the implementation of the O.E.O. performance contracting experiments. The author argues that it was not performance contracting, but the O.E.O. experiment which failed. The author blames this failure not so much on the poor evaluation design, but rather on the number of interface problems which arose…
