In response to recent trends and legislation, the concept of implementing evidence-based practices has become a critical component of contemporary schooling. It is important that teachers and families of students with disabilities understand the role that qualitative research plays in determining whether a practice is in fact evidence based.…

In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

The impact of academic programs--such as developmental mathematics programs--on student retention, has been a controversial topic for administrators, policy makers, and faculty in higher education. Despite deep interest in the effectiveness of these programs in retaining students, scholars have been unable to determine whether such programs have a…

There is a well known large and persistent association between education and health. This relationship has been observed in many countries and time periods, and for a wide variety of health measures. The differences between the more and the less educated are significant: in 1999, the age-adjusted mortality rate of high school dropouts ages 25 to…

This report uses meta-analysis to derive correlations between the variables of teacher immediacy, cognitive learning, and affective learning. A model was constructed such that the perception of teacher immediacy, a behavior, generates an intermediate outcome of affect, a motivation, which in turn increases cognitive learning outcome. The data…

Experiments offer more reliable evidence on causation than observational studies, which is not to gainsay the contribution to knowledge from observation. Experiments should be analyzed as experiments, not as observational studies. A simple comparison of rates might be just the right tool, with little value added by "sophisticated" models. This…

Community colleges, although being a potential source of future scientists and engineers, there are certain faults in the reform approach of these colleges that need to be addressed. The Multicultural Alliance for Technology, Research, and Information Exchange (MATRIX) model is presented to energize community colleges to create a science research…

This study tested a causal model of the prediction of the rate of occurrence of social and academic problems that results from college students' drinking. The model posited two pathways, one examining self-worth perceptions and symptoms of depression as mediators and one examining binge-drinking frequency as a mediator. Predictors included:…

Builds up a profile of causal development in 10-year-olds based on their recall of history and science texts in which the amount of causal connectivity differed. Finds that causal connections play an important role in expository text recall, and that subjects who have a strong causal profile also, generally, perform well in English. (PA)

Studied the construct validity of the dimensions of the Multidimensional-Multiattributional Causality Scale based on B. Wiener's attribution model (1979) in achievement and affiliation goal domains. Results for 172 New Zealand college students provide evidence that the measure is better used as a goal specific measure than a general measure. (SLD)

Investigates the long-term educational development of African American adolescents. The dependent variable was the highest level of education that participants ever expected to receive. Path models revealed differing processes for women and men. Overall, effects of early academic performance variables were strongest, followed by effects of family…

Tests the associations of sports ideology with sexist and antihomosexual attitudes in a sample of 304 college students. It was found that sports ideology is positively associated with sexist and antihomosexual attitudes but only among males. Reciprocal causal influences between sexist attitudes and sports ideology are discussed. (SLD)

Discusses linear structural relations, Two Stage Least Squares, and path analysis as statistical procedures that sometimes permit causal inferences from correlational findings. Even though two variables cannot be interpreted causally due to a possible but unknown third variable, these methods are appropriate for handling models with correlated…

Presents instructions for playing "Widgets and Blasters," an educational game designed to illustrate the functioning of a competitive market and help students understand economic models. Explains that the aims of the activity are to encourage students to identify the pattern of price over time and analyze the pattern in terms of…

Biases and models usually offered by cognitive and social psychology and by philosophy to explain causal induction are evaluated with respect to focal sets (contextually determined sets of events over which covariation is computed). A probabilistic contrast model is proposed as underlying covariation computation in natural causal induction. (SLD)
