An Investigation into the Dimensionality of TOEFL Using Conditional Covariance-Based Nonparametric Approach 总被引:1,自引:0,他引:1
This article reports two studies to illustrate methodologies for conducting a conditional covariance-based nonparametric dimensionality assessment using data from two forms of the Test of English as a Foreign Language (TOEFL). Study 1 illustrates how to assess overall dimensionality of the TOEFL including all three subtests. Study 2 is aimed at illustrating how to conduct dimensionality analyses for a testlet-based test by focusing on the Reading Comprehension (RC) section in combination with item content analyses and hypothesis testing. The results of Study 1 indicated that both TOEFL forms involve two dominant dimensions corresponding to the Listening Comprehension section and the combination of the Reading Comprehension section and Structure and Written Expression section. The extensive RC analyses from Study 2 revealed strong evidence that a significant amount of the RC multidimensionality came from testlet effects. Confirmatory analyses coupled with exploratory cluster analyses and substantive item content analyses further identified dimensionality structure having to do with reading subskills. 相似文献

Abstract This paper reports an experimental evaluation of a direct instruction procedure in which children are taught and practise activities to both foster and monitor their comprehension while reading. Three different class groups of low comprehenders, Standard 4, Form 1 and Form 2, were serially exposed to 21 days of 20‐25 minutes instruction in four study activities: summarising, questioning, clarifying and predicting. Instruction was by reciprocal teaching whereby the adult tutor and children took turns leading a dialogue centred around the important topics of the instructional text. The design of this study incorporated both with‐subjects multiple baseline and between‐subjects comparisons, the no treatment comparison groups being average and above average comprehending class peers. Daily comprehension assessment on a different text at the same difficulty level as that used for reciprocal teaching and pre and post intervention scores on a reading comprehension test served as the dependent measures for the study. Results show significant increases in accuracy on comprehension tests for all experimental groups upon introduction of the reciprocal teaching procedure. On completion of the intervention two of these groups scores matched those of the above average controls. Follow‐up probes eight weeks later showed that all groups had maintained their comprehension gains. 相似文献

Abstract Previous studies have shown that prior discussion, or the provision of context, both decrease oral reading errors and increase self‐correction amongst low‐progress and mentally retarded readers. This study investigated the effects of prior provision of context upon the reading behaviour of an above average reader. The results indicate that discussion of context (through examination of the relevant illustrations, asking and answering questions, and the verbal introduction of some new words in the text) both significantly decreased errors, and slightly increased the amount of self‐correction for this subject. 相似文献

This study examined the possible selves, goals, and perceptions of “time left” of older adults soon after they entered a life plan community as independent living residents. There has been little research regarding the effect of this life transition on older adults’ self-concept, hopes, and fears. Eighteen residents participated in one-hour personal interviews about their reasons for moving, their possible selves, goals, and perception of time left. Time left was measured in two ways: residents were asked to estimate the number of years they had left and were also asked to mark, on a novel visual analogue measure, how “limited” or “expanded” their time left felt to them. Residents were found to have an average of 6.18 possible selves in total, with more hoped-for possible selves (m = 4.39) than feared possible selves (m = 1.78). The majority of the goals were maintenance goals, followed by self-improvement goals and then avoidance goals. Residents estimated that they would live for 11.64 more years, and the majority reported that this felt like “a lot of time.” Based on their responses to the novel visual analogue measure of time left, two-thirds of the participants reported that their time left felt “expanded” rather than “limited.” Consistent with predictions based on socioemotional selectivity theory, participants with longer subjective life expectancies reported more self-improvement goals and more hoped-for selves. Participants identified more possible selves than documented in previous studies, including almost twice as many hoped-for possible selves. 相似文献

Counseling students learn about various theories, models, and career assessment measures during their training. However, the transition to practicum and internship often challenges students to decide on when to apply career theories and measures to specific problems. An assessment schema is proposed to assist counselor trainees with a systematic approach to conceptualizing a client's career problem. With this assessment schema, counselor educators can help trainees organize data into meaningful categories, reduce conceptual confusion, and engage students in the study of careers. 相似文献

Honeybees foraged from six locations, each of which was baited with sugar solution prior to each experimental trial. Under a variety of conditions, bees exhibited a small but reliable tendency to avoid revisits to locations that they had visited earlier during the experimental trial. These results replicate those of Brown and Demas (1994), who concluded that bees use working memory to discriminate previously visited locations from those not yet visited. The present experiments included procedures that allowed alternatives to this explanation to be more completely ruled out. The extent of spatial working memory performance exhibited by honeybees in these experiments appears to be limited by a process other than working memory capacity, perhaps the ability of bees to discriminate among several locations in close proximity to one another. 相似文献

This paper outlines the work of the Basildon Marital/Family Violence Project set up as a result of two studies undertaken by the National Society for the Prevention of Cruelty to Children (N.S.P.C.C.) School of Social Work, which looked at the effect of marital violence upon the children involved. These effects were classified under the following headings: (1) the children were scapegoated; (2) used as pawns in the marital battles; (3) turned agression against themselves; (4) had relationship problems at school; (5) were physically assaulted by the parents in 25% of the cases. The project, which is now in its 4th year, has offered social work services, consultation, training courses and research. Work with the families, and particularly with the children, has further emphasised the severe emotional damage that marital violence can have upon the children. The paper optimistically reports that after intensive work using a five-point treatment programme, and direct work with the children, there has been considerable diminution of violence in many of the cases and in some cases no repetition of such violence at all. The worker's approach, it is suggested, should be characterised by optimism combined with indestructible calm, genuine empathy combined with 24-hour access, persistence in the face of lack of progress, enhancement of parents' low self-esteem, regular contact and an ability to contain destructiveness. 相似文献

Kako (1999) reviews the evidence for syntactic competencies in several animal species exposed to artificial language systems, emphasizing the importance of core syntactic properties such as argument structure and closed-class items. We present evidence from our dolphin studies for the acquisition of the closed-class functionality of demonstratives, prepositions, conjunctions, and locatives. Sensitivity to argument structure is also evidenced by wholly untrained and consistent interpretations of the dolphin to probes of anomalous syntactic structures. These results are generated within our comprehension-based paradigm, which enables us to provide convincing objective evidence for the development and generalization of concepts by the dolphin subject. Demonstrations of animal language competencies may illuminate certain aspects of human linguistic competence by suggesting that the particular modeled subsets can derive from general cognitive mechanisms, rather than language-specific ones. 相似文献
