In this article, the authors argue that there are a range of effects usually studied within cognitive psychology that are legitimately thought of as aspects of critical thinking: the cognitive biases studied in the heuristics and biases literature. In a study of 793 student participants, the authors found that the ability to avoid these biases was…

The main impetus for the SPRinG (social pedagogic research into grouping) project was to address the wide gap between the potential of group work and its limited use in schools. It is an ambitious project that developed key principles and strategies to improve the effectiveness of group work in everyday primary classes and across a whole school…

This article presents a critique on K. Amon and A. Campbell's "Can children with AD/HD learn relaxation and breathing techniques through biofeedback video games?". Amon and Campbell reported a successful trial of a commercially available biofeedback program, "The Wild Divine", in reducing symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD)…

In this response, the authors dispel interpretation of their critical review of research on performance-approach goals as support for a dichotomous perspective of achievement goal theory. Challenges the suggestion that accepting recent research findings and adopting a multiple goals perspective constitutes a theoretical revision of the assumption…

The authors contend failure to confirm Weiner's theory is a result of shortcomings inherent in his model. They argue that cognitive theory has been properly represented and tested, and that the study of achievement behavior is enhanced by the addition of motivational, noncognitive assumptions to their theories. (Author/DWH)

Weiner's allegations of errors in testing his theory (presumed detrimental effects of investigating a restricted range of variables, use of expectancy changes as a mediating variable, and presumed inappropriateness of classroom performance as a dependent variable) are evaluated. Disconfirmation of Weiner's predictions occurs irrespective of…

Many researchers, including Buriel (EJ 187 987), incorrectly compared the results in each study with null hypotheses of zero differences between means or zero population correlations. Instead, a test of difference between the mean differences in the two samples or the direct comparison of the two sample correlations is required. (Author/CP)

Yarworth and Gauthier (EJ 189 606) examined whether self-concept variables enhanced predictions about students' participation in school activities, using unstructured stepwise regression techniques. A reanalysis of their data using hierarchial regression models tested their hypothesis more appropriately, and uncovered multicollinearity and…

The results of Seaver's (1973) quasi-experimental study of the effects of teacher expectancies on student achievement based on older sibling performance are reinterpreted as a regression artifact. That this rival explanation has not been recognized in the literature is probably due to the effects of researcher expectancies. (Author/BS)

This rejoinder to Brown and Weiner (TM 509 074) attempts to resolve areas of apparent conflict and to offer a broad synthesis around the self-worth theory of achievement motivation. The different yet compatible aspects of attribution and self-worth theories in regards to achievement effort are discussed. (BS)

In response to Covington and Omelich (TM 509 075) four main empirical points of agreement regarding achievement strivings are summarized. Four issues concerning the interrelationship of effort and ability attributions and self-worth that need theoretical and empirical resolution are discussed. (BS)

Data in Yarworth and Gauthier's article on student self- concept and participation in school activities (EJ 189 606) were reanalyzed by Walsh and Winne (TM 505 375). Yarworth and Gauthier's criticism of the reanalysis (TM 505 376) is answered. (GDC)

An explanation is sought for the striking apparent failure of the interactions of intelligence and memory factors with socioeconomic status predicted by Jensen's Level I/Level II theory, in a study by Stankov, Horn and Roy (EJ 239 630). It is suggested that Level I ability is a category of narrower abilities involving rote learning and primary…

Jensen's ideas about two levels of intellectual abilities are criticized as being oversimplified. More than two levels of intellectual abilities and relationships between variables reflecting more than racial and socioeconomic status (SES) differences are suggested, arguing that Jensen's statements about race and SES differences are not properly…

Although questioning is of interest to many fields, multidisciplinary approaches are rare. To reveal interrelationships between various literatures, a framework is formulated. The literatures on questioning in different fields are surveyed and compared. (Author/GK)
