Different research designs answer different questions. Educators cannot use nonexperimental quantitative research designs, such as descriptive surveys and correlational research, to determine definitively that an intervention causes improved student outcomes and is an evidence-based practice. However, such research can (a) inform educators about a…

Effect Sizes (ES) are an increasingly important index used to quantify the degree of practical significance of study results. This paper gives an introduction to the computation and interpretation of effect sizes from the perspective of the consumer of the research literature. The key points made are: (1) "ES" is a useful indicator of the…

Analysis of Pegnato and Birch's data invalidates the observation that teacher nominations should not be relied upon in gifted identification, as analysis shows that effectiveness and efficiency are related to number of subjects singled out as a result of the chosen cutoff value. An alternative is presented: compare correlation coefficients of the…
