Compares the effects of two prereading instructional treatments on students' comprehension of narrative and expository texts. Indicates that the teacher-directed condition is more effective than the interactive condition at promoting comprehension, and that both treatment conditions are superior to no prereading instruction at all.

This study examined effectiveness of a constant time delay (CTD) procedure in teaching social studies and health facts to five adolescents with learning or behavioral disorders. Students were given praise with and without additional information. Results indicated CTD procedures were reliable and effective, and students acquired nontargeted as well…

Advocates using baseball statistics to illustrate the advantages of specialization in production. Using Babe Ruth's record as an analogy, suggests a methodology for determining a player's comparative advantage as a teaching illustration. Includes the team's statistical profile in five tables to explain comparative advantage and profit maximizing.…

Argues that students often memorize, without critical analysis, components and processes of subjects in the sociology curriculum. Suggests that using cross-cultural, comparative material is a means of stimulating the critical energy of students, and subverting the tendency toward uncritical acceptance of factual "nuts and bolts."

Using simulated and real data, this study compares the performance of three methodologies for assessing unidimensionality: (1) DIMTEST; (2) the approach of Holland and Rosenbaum; and (3) nonlinear factor analysis. All three models correctly confirm unidimensionality, but they differ in their ability to detect the lack of unidimensionality.…

The usefulness of a two-step version of the Mantel Haenszel procedure for distinguishing between differential item functioning (DIF) and item impact was studied by comparing the single-step and two-step procedures using a simulated data set. Results show changes in the identification rate for the two-step methods. (SLD)

Presents a comparison of collocation-based similarity measures for the proper selection of additional search terms in query expansion. Highlights include evaluating retrieval effectiveness in a vector space model, thesauri, document ranking, and experiments on two Korean test collections. (Author/LRW)

Compares the effects of three different methods of improving reading comprehension: text-structure instruction, reading practice, and guided reading. Finds that standardized tests showed no one method to be more effective than another, but that all three methods had measurable effects on reading comprehension. (SR)

Focuses on synthesis in research--the combination of thesis and antithesis in the dialectical process, producing a new and higher form of being. Discusses kinds of synthesis (unique communication, plan of operation, abstract relations); synthesizing information pieces; summary practice leading to synthesis; and questions of analysis and synthesis.…

Evaluates "College & Research Libraries" and "Journal of Academic Librarianship" on the basis of types of articles published, structure of articles, types of statistics used, and data-collection methods. Results indicate that surveys are the primary form of data collection and descriptive statistics are used more frequently…

Draws attention to the validity of the Oakland School Board's resolution on Ebonics and to the value of English-as-a-Second-Language (ESL)-based approaches to teaching standard American English to speakers of other dialects. Demonstrates validity of comparisons made between monodialectal speakers of African-American language/Ebonics and ESL…

Describes an application of the Cross-Cultural Adaptability Inventory (CCAI) to measure the effects of two ways to teach about German culture in beginning language courses. Qualitative analysis of results established that the treatment group, taught with constructivist, process-oriented tasks experienced significantly positive results on the CCAI…

Pseudo-Maximum Likelihood (p-ML) and Asymptotically Distribution Free (ADF) estimation methods for estimating dynamic factor model parameters within a covariance structure framework were compared through a Monte Carlo simulation. Both methods appear to give consistent model parameter estimates, but only ADF gives standard errors and chi-square…

Reviews and compares the following nine laptop computers, focusing on their capabilities for multimedia presentations: Apple Macintosh PowerBook G3, Chem USA ChemBook 9780, Compaq Armada 7792DMT, Dell Inspiron 3000 mZ66xT, Hewlett-Packard OmniBook 3000CTX, IBM ThinkPad 770, Micro Express NP8233MMX, NEC Versa 6260, and Panasonic CF-63. Evaluation…

Compared the final exam performance of two classes of accounting students based on the method of course assessment used; one class received formative assessment with feedback prior to the final exam, while the previous class did not. Findings seemed to suggest that changing assessment to a formative mode can improve students' performance. (EV)
