This study represents the first phase of an ongoing research program aimed at identifying the dimensions of reading attitude and determining how these dimensions relate to a broader range of variables such as reading achievement, scholastic aptitude, classroom behavior, and cognitive styles. The 150 items which comprise the experimental edition of A Survey of Reading Altitudes (Wallbrown, Brown, & Engin, 1974) were factor analyzed along with measures of scholastic aptitude, reading vocabulary, and reading comprehension. The analysis was based on the responses of 853 intermediate grade students. The attitude items were presented orally to control for reading problems, but the students also had booklets so they could read the items to themselves. Seven independent dimensions of reading attitude and one reading achievement factor were identified, interpreted, and discussed. The findings are encouraging, since they suggest that investigating the expressed reading attitudes of intermediate grade children constitutes a promising line of educational research.  相似文献

Six Kansas school psychologists structured their teacher consultation in terms of three consultative modes which varied primarily in the number of follow-up contacts. The findings indicated that follow-up contacts led to greater teacher implementation of recommendations, greater perceived pupil behavior improvement, and greater sense of cooperative planning by the teachers. These outcome differences occurred between follow-up contacts and no follow-up contacts, with outcome differences not occurring between more and less extensive contacts.  相似文献

Fifty-nine children in kindergarten, first, and second grade were given the WISC information and arithmetic subtest. Approximately three weeks later, the subjects were presented with the same questions, and four multiple choice answers were shown and read to them. The number of correct responses on each subtest for each presentation method was recorded. The multiple choice method of presentation response yielded significantly higher scaled scores than did the standard WISC presentation with the free response mode of testing.  相似文献

BackgroundIndividuals with diabetes have greater central arterial stiffness, wave reflections, and hemodynamics, all of which promote the accelerated cardiovascular pathology seen in this population. Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness, wave reflections, and hemodynamics in healthy individuals; however, the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes. Recently, implementation of high-intensity interval exercise (HIIE) has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise. Yet, the effect of HIIE on the aforementioned outcomes in people with diabetes is not known. The purpose of this study was to (i) describe the central arterial stiffness, wave reflections, and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise (MICE) in adults with diabetes; and (ii) compare the effects of HIIE and MICE on the aforementioned outcomes.MethodsA total of 24 adult men and women (aged 29–59 years old) with type 1 (n = 12) and type 2 (n = 12) diabetes participated in a randomized cross-over study. All participants completed the following protocols: (i) HIIE: cycling for 4 × 4 min at 85%–95% of heart rate peak (HRpeak), interspersed with 3 min of active recovery at 60%–70%HRpeak; (ii) MICE: 33 min of continuous cycling at 60%–70%HRpeak; and (iii) control (CON): lying quietly in a supine position for 30 min.ResultsA significant group × time effect was found for changes in central systolic blood pressure (F = 3.20, p = 0.01) with a transient reduction for the HIIE group but not for the MICE or CON groups. There was a significant group × time effect for changes in augmentation index at a heart rate of 75 beats/min (F = 2.32, p = 0.04) with a decrease following for HIIE and MICE but not for CON. For all other measures of central arterial stiffness and hemodynamics, no significant changes were observed (p > 0.05).ConclusionA bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE; however, both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes. There was no significant difference in response to HIIE and MICE in all outcomes. This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes.  相似文献

The relationships between three measures of locus of control and eight dimensions of reading attitude were investigated for a sample of 431 inner-city children. The sample included the intermediate grade children enrolled in the 20 regular classrooms of the three elementary schools from the Columbus, Ohio, Public Schools. Correlation coefficients were computed between locus of control scores and the eight dimensions of reading attitude. Reading Anxiety showed a significant relationship with the I- score. This finding suggests that inner-city children who are willing to accept personal responsibility for negative events in their lives also tend to experience more anxiety about their reading. The other seven dimensions of reading attitude were not significantly related to internality scores.  相似文献

Groups of emotionally disturbed and nondisturbed elementary and junior high subjects were tested for ability to recognize primary emotions in facial expressions. Emotionally disturbed groups were found to be significantly less proficient both for overall emotion recognition ability and for several individual emotions. On the whole, the junior high groups were found to be better identifiers of emotion than the younger groups, but precise relationships between emotion recognition ability and age and also intelligence were unclear. Several possible interpretations of these findings and their implications for educational planning are discussed, and suggestions for additional research are presented.  相似文献

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.  相似文献

Preschoolers' scores on the Developmental Test of Visual Motor Integration (VMI), the Slosson Intelligence Test (SIT), and the ABC Inventory (ABCI) were analyzed for race and sex differences. Separate ANOVAs revealed no race effect on the VMI, whereas race differences favoring whites were found for the SIT and ABCI. There were no effects for sex on any measure, nor were there any interactions. Results are discussed in terms of the inconsistent findings for race effects in the perceptual-motor literature.  相似文献
