Relationships between epistemic beliefs and achievement goals: developmental trends over grades 5–11
Winberg T. Mikael Hofverberg Anders Lindfors Maria 《European Journal of Psychology of Education - EJPE》2019,34(2):295-315
Examining how students’ epistemic beliefs (EB) influence their cognition is central to EB research. Recently, the relation between students’ EB and their motivation has gained attention. In the present study, we investigate the development of the relationship between students’ EB and their achievement goals (AG) over grades 5–11. Previous studies on this topic are limited, in both number and range, and have produced inconsistent results. We performed a cross-sectional study, ranging over grades 5–11, and a 3-year longitudinal study (n = 1230 and 323, respectively). Data on students’ EB and AG were collected via questionnaires. Confirmatory factor analysis (CFA) supported a two-factor goal model (Mastery and Performance goals) and a structure of students’ EB comprising Certainty, Source, Development, and Justification. For each grade, students’ CFA scores on the respective goals were regressed on their scores on the EB dimensions by orthogonal projection to latent structures analysis. Although results indicated a weak relation between students’ EB and AG, trends in the cross-sectional data were largely replicated in the longitudinal study. Though naïve EB were in general associated with performance goals and sophisticated EB with mastery goals, the transition to upper secondary school was associated with changes in the relationship between students’ EB and AG. We discuss how the commonly used formulations of EB items may affect their ability to measure the naïve-sophisticated continuum, in turn affecting the predictive roles of EB dimensions.

Children in foster care frequently have histories of physical/sexual abuse and neglect, increasing their risk for externalizing behaviors (EB; e.g., aggression). According to the differential susceptibility theory, children with reactive temperaments (e.g., negative emotionality) may be particularly vulnerable to early maltreatment, but may also benefit the most from environmental enrichment such as family cohesion. In a high-risk longitudinal sample of 82 children adopted from foster care in Los Angeles County from 1996 and 2001, we examined predictions of EB from childhood to adolescence/young adulthood from temperament, preadoption maltreatment, and adoptive family cohesion. Overall, results from generalized linear models and generalized estimating equations (GEE) did not support differential susceptibility theory – specifically, youth with early reactive temperament did not exhibit heightened sensitivity to maltreatment nor to later adoptive family cohesion. Instead, reactive temperament was associated with higher EB at initial adoptive placement and escalating EB across childhood, controlling for age, gender, race-ethnicity, preadoption maltreatment, and adoptive family cohesion. Preadoption maltreatment history was unrelated to baseline EB, although sexual abuse history predicted escalating childhood EB post-adoption, whereas exposure to family violence (e.g., domestic violence) inversely predicted EB over time. By late adolescence/young adulthood 11–15 years post-adoption, rates of arrest and substance use in this sample were relatively comparable to normative populations of youth, although older age of adoption predicted more substance use in late adolescence/young adulthood. Findings highlight early reactive temperament and preadoption maltreatment as important risk factors to target for ameliorating patterns of EB growth in the first few years of adoption. 相似文献

Male and female rabbits received Pavlovian conditioning in which a 1, 216-Hz tone served as the CS and a 3-mA paraorbital electric shock train served as the US. Eyeblink (EB) and heart rate (HR) CRs were assessed. Half of the animals received prior exposure to the CS, while half were restrained in the chamber for a similar length of time but did not receive prior CS exposure. Different groups of each sex received three different CS intensities including 60, 75, and 90 dB (SPL) during both preexposure and conditioning. The results revealed that latent inhibition of the EB CR occurred only at the intermediate CS intensity, as indicated by a significant impairment of EB conditioning in this group. However, the magnitude of the decelerative HR CR was attenuated by prior CS exposure at all three CS intensities. Females showed faster EB conditioning than males, but latent inhibition occurred in both sexes. These results suggest that somatomotor and autonomic systems are affected differently by prior CS exposure. 相似文献

In Belgium, the Exam Board (EB) and the Secondary School for Adults (SSA) are two different ways to attain a secondary diploma after leaving secondary school without a diploma. The SSA is part of the regular educational system and organises courses with an adult approach. The EB is a flexible system in which students prepare themselves to do exams. Using survey data, we examined the effectiveness of both systems in diminishing the large inequalities in the Belgian educational system. Our analyses make clear that the EB and SSA attract different groups of unqualified school-leavers; as such they complement each other. Compared with those who never take a second chance, and thus stay unqualified, participants of the SSA and the EB seem to have a higher socio-economic background and less problematic school careers. As such, neither the SSA, nor the EB seems to be very effective in mitigating social inequality. 相似文献

This article describes a preliminary investigation of an empirical Bayes (EB) procedure for using collateral information to improve equating of scores on test forms taken by small numbers of examinees. Resampling studies were done on two different forms of the same test. In each study, EB and non-EB versions of two equating methods—chained linear and chained mean—were applied to repeated small samples drawn from a large data set collected for a common-item equating. The criterion equating was the chained linear equating in the large data set. Equatings of other forms of the same test provided the collateral information. New-form sample size was varied from 10 to 200; reference-form sample size was constant at 200. One of the two new forms did not differ greatly in difficulty from its reference form, as was the case for the equatings used as collateral information. For this form, the EB procedure improved the accuracy of equating with new-form samples of 50 or fewer. The other new form was much more difficult than its reference form; for this form, the EB procedure made the equating less accurate. 相似文献

We developed an empirical Bayes (EB) enhancement to Mantel-Haenszel (MH) DIF analysis in which we assume that the MH statistics are normally distributed and that the prior distribution of underlying DIF parameters is also normal. We use the posterior distribution of DIF parameters to make inferences about the item's true DIF status and the posterior predictive distribution to predict the item's future observed status. DIF status is expressed in terms of the probabilities associated with each of the five DIF levels defined by the ETS classification system: C–, B–, A, B+, and C+. The EB methods yield more stable DIF estimates than do conventional methods, especially in small samples, which is advantageous in computer-adaptive testing. The EB approach may also convey information about DIF stability in a more useful way by representing the state of knowledge about an item's DIF status as probabilistic. 相似文献
