This study aimed at determining the effectiveness of using reflection in developing Tourism and Hospitality students' oracy in English. Two modes of reflection (i.e., "active reflection" and "proactive reflection") were used for developing two aspects of oracy: language awareness of some features of spoken language (i.e.,…

Many students struggle with statistical concepts such as interaction. In an experimental group, participants took a paper-and-pencil test and then were given training to establish equivalent classes containing four different statistical interactions. All participants formed the equivalence classes and showed maintenance when probes contained novel…

TO STUDY THE EXACT DISTRIBUTIONAL DIFFERENCES BETWEEN SMALL, RELATED-SAMPLE PERCENTAGES AND THE ACCURACY OF LARGE-SAMPLE TESTS, SOME SIX HUNDRED SAMPLING DISTRIBUTIONS WERE CONSTRUCTED BY RANDOMIZATION. EXACT PROBABILITY FIGURES IN THE .204-.005 RANGE WERE TABULATED. THE TABLE OF SIGNIFICANCE VALUES EXTENDS TO SAMPLES YIELDING MATRICES VARYING IN…

Discusses the problem of assigning subjects to one of several treatments based on their test scores. The success of each treatment is measured by different criterion. (RB)

The difference between the success rates in two treatment groups is related to the treatment-outcome correlation and the overall success rate. A new measure of effect size is proposed, which is easily calculated and interpretable in terms of the ratio of success rates in the treatment groups. (Author/BW)

This study dealt with the nature of experimental control and the types and consequences of its errors or compromises in executing an experimental design for research on counseling or therapy. (Author)

Twenty-three journal articles on program evaluations were surveyed for incidence of four unethical practices: withholding purpose or mere existence of an evaluation from participants; exposure to stress; invasion of privacy; and denial of program benefits to control groups. Few violations were apparent. (CP)

Comments on S. Pogrow's suggestion that educational programs should be judged by the degree to which schools using them achieve "surprising scores." Emphasizes the importance of the use of control groups in program evaluation. (SLD)

Among the sciences, the practice of geology is especially visual. To assess the role of spatial ability in learning geology, we designed an experiment using: (1) web-based versions of spatial visualization tests, (2) a geospatial test, and (3) multimedia instructional modules built around QuickTime Virtual Reality movies. Students in control and…

In order to determine the effects of gender and scholastic ability on vocabulary retention and reading comprehension in a foreign language, 181 men and women enrolled in a first-year Spanish course were asked to either read a passage in Spanish on a computer and create annotations for a list of words found in the passage (experimental group), or…
