Computerized adaptive testing offers the possibility of gaining information on both the overall ability and cognitive profile in a single assessment administration. Some algorithms aiming for these dual purposes have been proposed, including the shadow test approach, the dual information method (DIM), and the constraint weighted method. The current study proposed two new methods, aggregate ranked information index (ARI) and aggregate standardized information index (ASI), which appropriately addressed the noncompatibility issue inherent in the original DIM method. More flexible weighting schemes that put different emphasis on information about general ability (i.e., in item response theory) and information about cognitive profile (i.e., in cognitive diagnostic modeling) were also explored. Two simulation studies were carried out to investigate the effectiveness of the new methods and weighting schemes. Results showed that the new methods with the flexible weighting schemes could produce more accurate estimation of both overall ability and cognitive profile than the original DIM. Among them, the ASI with both empirical and theoretical weights is recommended, and attribute‐level weighting scheme is preferred if some attributes are considered more important from a substantive perspective.  相似文献

De la Torre and Deng suggested a resampling‐based approach for person‐fit assessment (PFA). The approach involves the use of the statistic, a corrected expected a posteriori estimate of the examinee ability, and the Monte Carlo (MC) resampling method. The Type I error rate of the approach was closer to the nominal level than that of the traditional approach of using along with the assumption of a standard normal null distribution. This article suggests a generalized resampling‐based approach for PFA that allows one to employ or another person‐fit statistic (PFS) based on item response theory, the corrected expected a posteriori estimate or another ability estimate, and the MC method or another resampling method. The suggested approach includes the approach of de la Torre and Deng as a special case. Several approaches belonging to the generalized approach perform very similarly to the approach of de la Torre and Deng's in two simulation studies and in applications to three real data sets, irrespective of the PFS used. The generalized approach promises to be useful to those interested in resampling‐based PFA.  相似文献

This study examined English as a foreign language (EFL) spelling development amongst 233 fifth‐grade, eighth‐grade and 10th‐grade Hebrew first‐language speakers to examine effects of English orthographic exposure on spelling. Good and poor speller differences were examined regarding the acquisition of novel phonemes (/æ/, /Λ/ and //) and orthographic conventions (/ð/, /θ/, // and silent ‘e’). Hebrew measures included standardised spelling and orthographic and phonological tasks. Experimental English measures included real‐word and pseudoword spellings, orthographic tasks and standardised spellings. Results showed significant differences in spelling accuracy between good and poor spellers at all grades. Spelling accuracy for most conventions did not improve after the eighth grade. Spellings of consonantal clusters, initial h and /ð/ differed between good and poor spellers in the fifth grade only. Hebrew spelling was one of the strongest predictors of EFL real‐word and pseudoword spellings in both fifth and eighth grades. Implications for teaching practice are discussed.  相似文献

Neighborhood Latino ethnic concentration, above and beyond or in combination with mothers' and fathers' ethnic socialization, may have beneficial implications for minority adolescents' ethnic attitude and identity development. These hypotheses, along with two competing hypotheses, were tested prospectively (from  = 12.79–15.83 years) in a sample of 733 Mexican‐origin adolescents. Neighborhood ethnic concentration had beneficial implications for ethnic identity processes (i.e., ethnic exploration and perceived peer discrimination) but not for ethnic attitudes. For Mexico‐born adolescents, high maternal ethnic socialization compensated for living in neighborhoods low on ethnic concentration. Findings are discussed vis‐à‐vis the ways in which they address major gaps in the neighborhood effects literature and the ethnic and racial identity development literature.  相似文献

This meta‐analytic review includes 135 studies, representing 17 countries, of child and adolescent (ages 4–17) samples of overt and relational peer victimization and examines the magnitude of overlap between forms of victimization and associations with five social–psychological adjustment indices. Results indicate a strong intercorrelation between forms of victimization ( = .72). No gender difference with regard to relational victimization was found, but boys were slightly higher in overt victimization. Overt victimization is more strongly associated with overt aggression; relational victimization is more strongly related to internalizing problems, lower levels of received prosocial behavior from peers, and relational aggression. Both forms are related to externalizing problems. Age and method of assessment were explored as potential sources of variability in effect sizes.  相似文献

The percentage of students retaking college admissions tests is rising. Researchers and college admissions offices currently use a variety of methods for summarizing these multiple scores. Testing organizations such as ACT and the College Board, interested in validity evidence like correlations with first‐year grade point average (FYGPA), often use the most recent test score available. In contrast, institutions report using a variety of composite scoring methods for applicants with multiple test records, including averaging and taking the maximum subtest score across test occasions (“superscoring”). We compare four scoring methods on two criteria. First, we compare correlations between scores and FYGPA by scoring method. We find them similar (). Second, we compare the extent to which test scores differentially predict FYGPA by scoring method and number of retakes. We find that retakes account for additional variance beyond standardized achievement and positively predict FYGPA across all scoring methods. Superscoring minimizes this differential prediction—although it may seem that superscoring should inflate scores across retakes, this inflation is “true” in that it accounts for the positive effects of retaking for predicting FYGPA. Future research should identity factors related to retesting and consider how they should be used in college admissions.  相似文献

With integrated curricula and multidisciplinary assessments becoming more prevalent in medical education, there is a continued need for educational research to explore the advantages, consequences, and challenges of integration practices. This retrospective analysis investigated the number of items needed to reliably assess anatomical knowledge in the context of gross anatomy and histology. A generalizability analysis was conducted on gross anatomy and histology written and practical examination items that were administered in a discipline‐based format at Indiana University School of Medicine and in an integrated fashion at the University of Alabama School of Medicine and Rush University Medical College. Examination items were analyzed using a partially nested design in which items were nested within occasions (i:o) and crossed with students (s). A reliability standard of 0.80 was used to determine the minimum number of items needed across examinations (occasions) to make reliable and informed decisions about students' competence in anatomical knowledge. Decision study plots are presented to demonstrate how the number of items per examination influences the reliability of each administered assessment. Using the example of a curriculum that assesses gross anatomy knowledge over five summative written and practical examinations, the results of the decision study estimated that 30 and 25 items would be needed on each written and practical examination to reach a reliability of 0.80, respectively. This study is particularly relevant to educators who may question whether the amount of anatomy content assessed in multidisciplinary evaluations is sufficient for making judgments about the anatomical aptitude of students.

This meta-analysis examined concurrent associations between aggression, withdrawal, assertion, and prosocial behavior and each of positive and negative friendship quality across studies with 22,657 children and adolescents (Mage = 11.71 years; 51.7% girls; 67.7% White). Studies were published between 1995 to 2021 and 32.4% were conducted outside of North America. Aggression was linked to more negative,  = .19, 95% CI [.14, .24], and less positive,  = −.05 [−.08, −.01], friendships. Withdrawal was associated with less positive friendships,  = −.13 [−.18, −.08], whereas prosocial behavior was related to more positive,  = .29 [.22, .37], as well as less negative,  = −.16 [−.20, −.12], friendships. Assertion was related to more positive friendships,  = .15 [.01, .28].  相似文献

Children struggle to stop inappropriate behaviors. What interventions improve inhibitory control, for whom, and why? Prior work suggested that practice proactively monitoring for relevant signals improved children’s inhibitory control more than practice with motoric stopping. However, these processes were not clearly dissociated. This study tested 162 seven- to nine-year-old children (89 female, 72 male, 1 unreported; 82% White) on the stop-signal task, following monitoring or stopping-focused practice. Both methods improved inhibitory control, supported generalization, and interacted ( = .20–.73). Practice approaches differentially impacted variability ( = .01–.09). Only monitoring benefits showed signs of depending upon proactive control ( = .02). These findings highlight unique contributions of attentional and stopping processes to inhibitory control, suggesting possibilities for tailored interventions.  相似文献

Personality has been given several definitions. Nevertheless these may be classified into two categories, namely: (1) as an inner essential nature of man, and (2) as some outward appearance of man. The concept of personality held by the Yoruba people of Nigeria conforms to this dual pattern. The inner essence of personality is known as ori (inner head) while the external manifestation is iwa (character, behaviour). Two other components of the person are
gb
n
(wisdom) and i
(work or skill). Ori is independent and the prime motivator of human action. It is conceived of as both the carrier of destiny and as a kind of guardian angel. It is not subject to education.
gb
n
and i
on the other hand are the main objects of education. Much of iwa is determined by ori, but education for
gb
n
may modify iwa.Yoruba ontology of motivation stipulates that three factors are responsible for motivating human action: (1) Ori; (2) Aiye — the psychosocial environment; (3) Orisa — the pantheon of deities. Traditional education is mostly informal but some West African tribes operate formal schools known as poro or sande. Curricula in these schools conform to the Yoruba aims of education, thus confirming that there are probably strong communalities in aims of traditional education among several West African tribes.Western education has often led to conflicts in the educated individuals. Such conflicts often can be traced to failure to take account of the traditional perception of personality. A closer study of such perceptions of personality in each community may prove fruitful for diagnostic and remedial purposes in educational reform.  相似文献

The information matrix can equivalently be determined via the expectation of the Hessian matrix or the expectation of the outer product of the score vector. The identity of these two matrices, however, is only valid in case of a correctly specified model. Therefore, differences between the two versions of the observed information matrix indicate model misfit. The equality of both matrices can be tested with the so‐called information matrix test as a general test of misspecification. This test can be adapted to item response models in order to evaluate the fit of single items and the fit of the whole scale. The performance of different versions of the test is compared in a simulation study with existing tests of model fit, among them the test of Orlando and Thissen, the score test of local independence due to Glas and Suarez‐Falcon, and the limited information approach of Maydeu‐Olivares and Joe. In general, the different versions of the information matrix test adhere to the nominal Type I error rate and have high power for detecting misspecified item characteristic curves. Additionally, some versions of the test can be used in order to detect violations of the local independence assumption.  相似文献

Although school‐based programs are effective at decreasing bullying, the majority of studies have been conducted with elementary and middle school students. We conducted a pilot study using a randomized controlled design investigating the social validity of a brief, bullying bystander program adapted to be age‐appropriate for high school students (N = 65). Results indicated that high school students in the intervention group perceived the program to be acceptable and relevant and reported greater increases in knowledge ( = 0.27) and confidence to intervene ( = 0.27) in bullying situations compared to students in the control group. Despite being trained in the use of four intervention strategies, students reported using two of the strategies infrequently. Additionally, we found a significant difference between the intervention and control group for only one strategy (Φ = ?0.44). This study provides partial support for the social validity of the adapted program. Implications for implementing the program at the high school level are discussed.  相似文献

Children (N = 103, 4–9 years, 59 females, 84% White, c. 2019) completed visual processing, visual feature integration (color, luminance, motion), and visual search tasks. Contrast sensitivity and feature search improved with age similarly for luminance and color-defined targets. Incidental feature integration improved more with age for color-motion than luminance-motion. Individual differences in feature search ( β = .11) and incidental feature integration ( = .06) mediated age-related changes in conjunction visual search, an index of visual selective attention. These findings suggest that visual selective attention is best conceptualized as a series of developmental trajectories, within an individual, that vary by an object's defining features. These data have implications for design of educational and interventional strategies intended to maximize attention for learning and memory.  相似文献

Western literature suggests that young children overestimate their performance across a range of tasks. Research in non-Western cultures, however, is lacking. In 2019, 101 Chinese (52% girls) and 98 Dutch (49% girls) children, ages 4 and 5, were asked to estimate how well they would perform on both a motor and a memory task. Children from both countries overestimated their performance to the same extent ( = .077 and .027 for the motor and memory tasks, respectively). They generally persevered in doing so despite receiving realistic performance feedback. Yet, children overestimated their peers’ performance about as much as their own performance, in some cases even more. This is the first demonstration of performance overestimation in children growing up in a non-Western culture.  相似文献

Understanding disease transmission is a complex problem highlighted by the COVID-19 pandemic. These studies test whether 3- to 6-year-old children in the United States use information about social interactions to predict disease transmission. Before and during COVID-19, children predicted illness would spread through close interactions. Older children outperformed younger children with no associations between task performance and pandemic experience. Children did not predict that being hungry or tired would similarly spread through close interactions. Participants include 196 three- to six-year-olds (53% girls, 47% boys; 68% White, 9% Black, 7% Asian, 6% Hispanic or Latinx), with medium-sized effects (d = .6,  = .3). These findings suggest that thinking about social interaction supports young children's predictions about illness, with noted limitations regarding children's real-world avoidance of disease-spreading behaviors.  相似文献

We employ new data to examine how public higher education institutions adjusted the salaries and composition of their business faculty during a financially challenging period. The data's multilevel structure allows us to describe changes in between-institution inequality, within-institution inequality, and their interaction. To examine the role of finances, we compare public and private institutions and employ difference and fixed-effects models to study the effect of state appropriations. Our results indicate that financially stressed publics almost matched the salary increases of their competitors between 1999 and 2006, but reductions in the number of professorsespecially full professorsaccompanied this salary growth. The salary gap across public institutions increased, while within institutions, salary compression and salary inequality within rank grew.  相似文献
