Summarizes a 10-year Chinese secondary school chemistry teaching experiment, programmed elicitation, which was found to be more effective than traditional Chinese elicitation. Includes sample programmed elicitation textbook section and lesson. (Author/MKR)

Explores the nature of meta-analysis by placing it in the context of research synthesis. Methods of meta-analysis are described and compared with other forms of research integration, and findings for several meta-analyses are provided to show advantages of quantitative review methods. (SLD)

Factors that might bias outcomes of meta-analytic reviews are discussed. The role of meta-analysis in theory development is considered, describing three types of meta-analytic tests of theory. A final section discusses the applicability of meta-analysis in the assessment of convergent and discriminant construct validity. (SLD)

Some guidelines are offered for interpreting and evaluating meta-analytic reviews of research. The choice of unit of analysis, the issue of fixed versus random effects, the meaning of heterogeneity, the determination of appropriate contrasts, and the choice of measures of central tendency are discussed. (SLD)

Basic rules are suggested to replace the signed coefficient rule to infer the form of moderator effects in terms of slopes of regression lines. Steps are provided to interpret the form of moderator effects that can be achieved using only the regression coefficients of the predictor variable and interaction term. (SLD)

In contrast to the average effect sizes of the approach to metanalysis that can be thought of as literature synthesis, an effect-size surface is proposed as a function of scientifically relevant factors, estimated by extrapolating a response surface of observed effect sizes to a region of ideal studies. (SLD)

Meta-analysis is proposed as an effective alternative to conventional narrative review for extracting trends from research findings. This type of analysis is explained, advantages over more traditional review techniques are discussed, basic procedures and limitations are outlined, and potential applications in dental education and clinical…

Presents discussion of various studies of the effect of television on aggressive behavior. Argues for a positive and significant correlation between television violence and aggressive behavior. Performs additional tests to solidify conclusions. Provides substantive interpretation. (HB)

Describes how the statistical technique of meta-analysis can be used to help resolve conflicting studies in social sciences. (ZWH)

This study combined the concept of self-control with Keller's ARCS (Attention, Relevance, Confidence, Satisfaction) model of motivational design to determine whether students could be trained to make instruction relevant to themselves by using metalearning strategies. Results suggest students can be trained to do this and that this training can…

A metanalysis involving 62 studies compared the response rate to mailed surveys with and without a monetary gratuity. The average response rate increased 19% when a gratuity was enclosed. Other findings that substantiate that the external validity of surveys can be increased by gratuities are discussed. (SLD)

Kendall's Tau is often considered equivalent to Spearman's Rho as an ordinal measure of correlation in spite of its different metric. Formulas for converting Tau to Rho are reviewed; and a table of corresponding values is presented for Tau, Rho, and several related indices. (SLD)

Examines whether behavioral intentions (BI) mediate between attitudes (A) and behaviors (B). Finds A-BI correlation higher than A-B correlation, BI-B correlation higher than A-B correlation, A-BI correlation higher than BI-B correlation, variation in BI-B correlations greater than A-BI, and attitudinal relevance affected the magnitude of A-BI…

Presents a meta-analysis of 25 primary research studies of managerial gender communication issues. Addresses issues of behavioral differences and research methodologies. Concludes that communication differences between male and female managers are minimal and of little social importance. Suggests the use of an interactionist perspective in future…

This meta-analysis of 33 studies compared the pragmatic language skills of 825 students (ages 3-12) having language and/or learning disabilities with the skills of nondisabled peers. The students with disabilities demonstrated consistent and pervasive pragmatic deficits in conversation, which were more attributable to underlying language deficits…
