Two groups of gifted adolescents solved two similar intelligence tests with differing levels of task difficulty in reverse order. Under both conditions the performance level on the less complex test was much lower, a result not observed in a control group of average intelligence. Behavioural observations revealed that the low performance of the gifted students was combined with lack of effort. This performance pattern is discussed with respect to recent postulates of achievement motivation theory, which empasize the impact not only of the achievement motive, but also of the informational value of a given task for evaluating own level of ability. It is argued that the perceived informational value of the easier test was not high enough to create an incentive for the gifted students to perform at the highest possible level 相似文献

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of
second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only,
which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary
word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and
draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical
instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through
each of the interventions, being exposed to a different treatment condition for each category of words. Participants were
measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension
measures. While no statistical significance was shown between the interventions across the word categories, a significant
difference was found between the Image Creation and Word Only interventions within the science terms category. Students also
reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications
for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary
learners using imagery methods. 相似文献

Predoctoral interns' responses to an internship supervision training questionnaire indicated that counseling center interns supervised more trainees, received more supervision in their supervisory roles, reported more supervision training activities, and yielded higher supervisor development scores than did non‐counseling‐center interns. A qualitative analysis of participants' responses showed that non‐counseling‐center interns desired more supervision training and opportunities to provide supervision during their internship year than did counseling center interns. 相似文献

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

We revisit the relationship between attendance and performance in the undergraduate university setting and apply agency theory in the instructor–student context. Building on agency theory propositions in the educational setting advanced by Smith, Zsidisin, and Adams (2005) , we propose that the student and instructor must align goals to promote the student's achievement of performance learning outcomes, and attendance functions as a behavior‐based alignment mechanism to encourage the convergence of faculty and student interests. Further, we propose that attendance does not equally affect lower‐ and higher‐performing students and that absences are also negatively related to students' cumulative grade point average. We test these hypotheses with data from undergraduates enrolled in management courses at a state university in the southeast. Our results show that attendance is positively related to exam performance, there are more pronounced negative effects of an absence for lower‐performing students than for higher performers, and absences are negatively related to a student's cumulative grade point average. We discuss the implications of our findings for students, instructors, and universities as well as practice in teaching and learning. 相似文献

This article focuses on the evaluation of thesis supervision and highlights the vast range of problem areas presently documented as significant areas of concern for both graduate students and their supervisors. Additionally, the authors report on a study completed in 1995, which surveyed all Australian universities about current evaluative practices in postgraduate supervision. The conclusion of this study was that the conduct of such evaluations appears to be minimal and is primarily designed to obtain an indicator of the general health of a university's postgraduate supervision rather than to foster improved supervisory practices. As part of the same study, the authors conducted University faculty-based student and supervisor focus groups. Key issues emerging from these focus groups were: (1) the importance of relational aspects of supervision as the student communicates over the long term with one or more supervisors; (2) the importance of systematic feedback, monitoring, and evaluation to the supervisory process; and (3) the lack of strategies to facilitate this evaluative feedback process. On the basis of these findings, the authors designed evaluative strategies to facilitate regular ongoing feedback between students and supervisors. 相似文献

Thirty‐six children with cerebral palsy, aged 3.5 to 4.5 years were compared on their skills for independence. Of the 36 boys and girls, 19 children were enrolled in a Conductive Education Program in Birmingham and 17 were enrolled in British special education programs in the Greater Manchester area. Skills for independence were measured with the Vineland Adaptive Behavior Scales via teachers’ responses, once a year on three occasions. Parents were interviewed using the Developmental Profile 2, once a year on three occasions. The results of two‐way ANOVA with one repeated measure on both teachers’ and parents’ responses indicate that there was no significant difference between the two groups in their skills for independence. However, both groups performed significantly better as they were getting older. Despite the strong emphasis on independence in Conductive Education, the children's level of independence was no different from their counterparts. Thus, the claim for the effectiveness of Conductive Education is not supported by the study. 相似文献

Developing local oral reading fluency cut scores for predicting high‐stakes test performance 下载免费PDF全文

This study evaluated the classification accuracy of a second grade oral reading fluency curriculum‐based measure (R‐CBM) in predicting third grade state test performance. It also compared the long‐term classification accuracy of local and publisher‐recommended R‐CBM cut scores. Participants were 266 students who were divided into a calibration sample (n = 170) and two cross‐validation samples (n = 46; n = 50), respectively. Using calibration sample data, local fall, winter, and spring R‐CBM cut scores for predicting students’ state test performance were developed using three methods: discriminant analysis (DA), logistic regression (LR), and receiver operating characteristic curve analysis (ROC). The classification accuracy of local and publisher‐recommended cut scores was evaluated across subsamples. Only DA and ROC produced cut scores that maintained adequate sensitivity (≥.70) across cohorts; however, LR and publisher‐recommended scores had higher levels of specificity and overall correct classification. Implications for developing local cut scores are discussed. 相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.
