Congruence between educational attitudes and academic philosophies

Kerlinger's theory of social attitudes asserts that attitudes toward educational practices can be represented by the independent dimensions of progres-sivism and traditionalism. This study focused on the relationship between these attitudes and the philosophies of realism and pragmatism. A sample of 152 graduate students in education completed three instruments measuring educational attitudes and the basic and applied philosophies. Factor analytic results supported a dualistic theory rather than a bipolar theory for attitudes and philosophies. Pragmatists supported the progressive referents of children's interests and social development as educational goals, while realistsy supported traditional concepts emphasizing structure and the learning of content. The results are discussed in terms of the consistency between educational attitudes and a teacher's philosophy.     

Technical characteristics of the peabody individual achievement test as a function of item arrangement and basal and ceiling rules

The effects that item order and basal and ceiling rules have on test means, variances, and internal consistency estimates for the PIAT mathematics and reading recognition subtests were examined. Seven items on the math subtest and one item on the reading recognition subtest were significantly easier or harder than their test placement indicated. The use of basal and ceiling rules had a pronounced effect on the means, variances, and reliabilities on the multiple choice math subtest, while the rules' effects on the reading recognition subtests were minor. Item order also affected scores on the math subtest.     

The effects of dependent and interdependent group contingencies on socially appropriate responses in classes for emotionally handicapped children

The effects of group dependent and group interdependent reinforcement contingencies on the level of socially appropriate behaviors emitted by emotionally handicapped elementary school students were examined. The investigation employed an ABAC design with a systematic replication (ACAB) across a second classroom. The findings suggested that: (a) Both group dependent and group interdependent reinforcement contingencies were effective in incieasing the level of socially appropriate behaviors. (b) For Classroom II, group interdependent reinforcement contingencies more often resulted in higher rates of responding for individual subjects than did group dependent reinforcement contingencies. (c) Group interdependent contingencies were shown to set the occasion for cooperative behavior among class members designed to help each other achieve individual but interdependent goals.     

A comparison of the PIAT and WRAT: A closer look

A sample of 46 white fourth-grade pupils was administered the PPVT, WRAT, and PIAT, except for PIAT Reading Comprehension and General Information. Subjects were selected randomly from those pupils whom classroom teachers judged to be doing at least average academic work. Mean grade equivalents, as well as intercorrelations, were examined for PIAT and WRAT subtests. No sex differences were found for PPVT IQ, age, or most achievement scores. Mean grade equivalents generally ranged between the sixth-and seventh-grade levels. Nearly all PIAT-WRAT intercorrelations were positive and significant, and highest for the similarly labelled subtests. Substantial differences were noted in mean grade equivalents. WRAT Reading and Spelling exceeded their PIAT counterparts by approximately one grade level. In contrast, PIAT Mathematics exceeded WRAT Arithmetic by more than one grade level. The possible effects of differences in item content and task structures on performance were discussed. Implications for practitioners involved in psychoeducational evaluations were considered.     

The effect of individual goal-setting conferences on academic achievement and modification of locus of control orientation

The study was designed to investigate the effects of individual goal-setting conferences on classroom achievement and locus of control orientation. Subjects were blocked on sex and previous achievement and randomly assigned to one of three treatment groups: the goal-setting (GS) group, which received weekly individual goal-setting conferences; the conference (Cf) group, which received weekly individual conferences but set no goals; and the control (C) group, which received no conferences. Analyses of the data showed a significant treatment effect for achievement across treatment groups, with the GS group having significantly higher achievement than the Cf and C groups. Treatment effect across locus of control measures across treatment groups was less clear, although post hoc analyses indicated that the GS group was significantly more internal than either the Cf or C groups on the three intellectually oriented measures.     

Matching teaching to learners: A review of a decade of research

Thirty-five studies relating to D. E. Hunt's notion of matching environments to learners were reviewed. The studies were grouped according to their outcome measures into affective, behavioral, and achievement outcomes. Empirical support for the matching principle was found for all three outcomes, but varied from strong support for affective and behavioral criteria to moderate support for achievement. The article discusses these differences, and advocates that future research studies give greater attention to the conceptualization and measurement of teaching environments. It concludes that there is empirical validation for the matching principle, and that matching is a meaningful way of describing the process of adapting instructional approaches to student differences.     

CERN: Past performance and future prospects: II. The scientific performance of the CERN accelerators

In a series of three papers, we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organization for Nuclear Research (CERN) over the period since 1960, and to assess the future prospects for CERN and its users during the next ten to fifteen years.We concerned ourselves in a previous paper (Paper 1 - Martin and Irvine [51] with the position of the CERN accelerators in world high-energy physics relative to those at other large laboratories working in the field. We dealt primarily with the period from 1969 to 1978, and attempted to establish how the experimental output from the three principal CERN accelerators, taken as a whole, compared with that from other major facilities. In undertaking this comparative evaluation, we drew on the method of “converging partial indicators” used in previous studies of three Big Science specialties.In contrast, this paper (Paper II) focuses in detail on the scientific performance of each of the CERN accelerators taken individually. In particular, it asks, first, how the outputs from the CERN 28 GeV (giga or billion electron-volts) Proton Synchrotron compare with those from a very similar 33 GeV American accelerator at Brookhaven National Laboratory over the past two decades? Second, how great have been the experimental achievements of the Intersecting Storage Rings in world terms? And, third, how do the outputs from the CERN 400 GeV Super Proton Synchrotron and from a rival American machine at Fermi National Accelerator Laboratory compare? Attempts are then made to identify the main factors responsible for determining the relative scientific performance of each CERN machine.These factors are of relevance to the subject of a third paper (Paper III - Martin and Irvine [52]) which sets out to assess the future prospects for CERN and in particular for LEP, the large electron-positron collider scheduled for completion in the latter part of the 1980s. What are the construction requirements (financial and technical) associated with LEP, and how easily will they be met? How does the scientific potential of LEP compare with that of other major accelerators under construction around the world? And, in the light of the previous record of the CERN accelerators, to what extent is this potential likely to be realized? The paper concludes with a discussion of the extent to which predictive techniques can be utilized in the formulation of scientific priorities, and of the problems in current science policy-making that such techniques might help address.
