The role of stimulus disparity in concurrently available reinforcement schedules

Eight White King pigeons were exposed to various two-component arrangements of concurrently available variable-interval reinforcement schedules. Line orientation stimuli associated with each component differed by 45,15, or 0 deg for different subjects. Relative responding matched relative reinforcement with 45 deg separation, while undermatching resulted with 15 deg separation and extreme undermatching resulted with 0 deg separation. Since obtained relative reinforcement indicated contact with the contingencies in all conditions of line orientation disparity, it is concluded that stimulus disparity between components of concurrently available reinforcement schedules is an important determinant of response distribution between components.     

A prospective investigation of appraisals as mediators of the link between interparental conflict and child adjustment

This longitudinal study tested the role of children's appraisals of threat and self-blame as mediators of the association between interparental conflict and child adjustment in a sample of 298 Welsh children ages 11 to 12 years. Exposure to higher levels of interparental conflict at Time 1 predicted greater perceived threat and self-blame at Time 2, after accounting for the effects of Time 1 adjustment and appraisals on later appraisals. Perceived threat in turn was associated with increased internalizing problems at Tune 2, and self-blame was associated with higher externalizing problems. The pattern of results was largely consistent for child and parent reports of conflict and for boys and girls, though some gender differences were found in associations between appraisals and adjustment.     

Validating NSSE Against Student Outcomes: Are They Related?

While there exist many examples of institutional use of the results of the National Survey of Student Engagement (NSSE), there is a relative paucity of research explicitly linking student outcomes to responses on the survey. A major Doctoral-Extensive institution in the Southeast recently conducted a large-scale implementation of the National Survey of Student Engagement (NSSE). We have linked multiple years of NSSE responses to several student outcomes: freshman retention, GPA, pursuit of graduate education, and employment outcome upon commencement/degree conferral. Our research finds minimal explanatory power in the NSSE benchmarks for these outcomes. A statistically derived model from the individual NSSE items shows greater promise, although there are difficulties in replicating the model for previous student cohorts.

Do teachers’ own learning behaviors influence their classroom goal orientation and control ideology?

This study explored the relationship between teachers’ own learning behaviors and their teaching practices. Experienced teachers taking graduate courses responded to an instrument measuring their self-regulated learning as students and their teaching practices as indicated by how they conveyed the purpose of engaging in academic work (i.e., goal orientation) and their approach toward discipline (i.e., control ideology). The data were analyzed using structural equation modeling. The results indicate that teachers own self-regulated learning behaviors influence the extent to which teachers convey a mastery goal orientation, which in turn leads to a more humanistic control ideology. Implications for teacher education programs are discussed.     

Similarity grouping of Australian universities

The Unified National System of Australian Universities was created out of universities, institutes of technology and colleges of advanced education. In this study similarity clustering of universities within this system is attempted based on two data sets: one based on evaluative ratings and the other on quantitative performance indicators. With the exception of three traditional universities that tended to cluster together across data sets no consistent clustering emerged. Within data sets there was no tendency for the emergent clusters to reflect the origins of the institutions in any consistent manner. It is suggested that the Unified National System has not reduced diversity.     

The Validity of National Curriculum Assessment

This paper reviews the validity of National Curriculum assessment in England. It works with the concept of 'consequential validity' (Messick, 1989) which incorporates both conventional 'reliability'issues and the use to which any assessment is put. The review uses the eight stage 'threats to validity'model developed by Crooks, Kane and Cohen (1996). The complexity of National Curriculum assessment makes evaluation difficult. These assessments are used for a variety of purposes so that the 'consequential'aspects are compounded. National Curriculum assessment also involves both Teacher Assessment and tests – each of which has strengths and limitations in relation to validity. The main finding is that the validity of National Curriculum assessment hinges on the balance between Teacher Assessment and testing. Between them they can meet Crooks et al.' s requirements of a valid assessment system. The current emphasis on the use of test results for school accountability and as a measure of national standards has undermined Teacher Assessment to a point at which the validity of the system is in question.     

Apprenticeship in literacy

A four-level taxonomy is proposed for categorizing the ways in which literacy is defined operationally in education. The four levels—performative, functional, informational, epistemic—are distinguished in terms of conceptualizations of the relationships between writing and speaking and between writing and thinking. This taxonomy is then used to examine the results of recent research on early literacy development. Two major findings emerge: (a) the universal predisposition among children to develop actively an understanding of the forms and functions of written language and (b) differences between cultural groups in the ways literacy activities are organized. It is argued that an emphasis should be placed on the highest level of literacy in the school curriculum and that this should be the case forall children and at all ages.
