Increasing evidence indicates that individuals with Intellectual Disabilities (ID) might benefit from phonics‐based reading instruction. However, research and instruction in this field has predominantly focused on sight word reading. Models for complex interventions recommend that feasibility research be conducted prior to conducting randomised studies to assess efficacy of interventions (Thabane et al., 2010). The aim of the current paper is therefore to investigate feasibility questions relating to conducting a full‐scale randomised controlled trial (RCT) evaluation of an online, phonics‐based reading programme (Headsprout? Early Reading; HER) with children with ID. Employing a randomised pre‐test post‐test group design, this study explores and trials important aspects of a RCT evaluation to inform a full‐scale RCT. We also found that HER had a significant effect on reading skills when compared with ‘education as usual’, with large effect sizes on the main outcome measure. This indicates that further, more robust evaluations using HER with children with ID are a worthwhile pursuit.  相似文献

The impact of misspecifying covariance matrices at the second and third levels of the three-level model is evaluated. Results indicate that ignoring existing covariance has no effect on the treatment effect estimate. In addition, the between-case variance estimates are unbiased when covariance is either modeled or ignored. If the research interest lies in the between-study variance estimate, including at least 30 studies is warranted. Modeling covariance does not result in less biased between-study variance estimates as the between-study covariance estimate is biased. When the research interest lies in the between-case covariance, the model including covariance results in unbiased between-case variance estimates. The three-level model appears to be less appropriate for estimating between-study variance if fewer than 30 studies are included.  相似文献

Attitudinal data were collected for a sample of 492 parents and public school children before implementation of a metropolitan desegregation plan and for 2 years after implementation. The variables measured included racial attitudes, feelings out desegregation, and school-related attitudes. There were small but significant changes on 7 of the 11 measures, with most of the changes occurring during the first year. There were race and grade-level differences on some of the variables before desegregation, but race and grade level were generally not related to changes over time.This research has been supported by a grant from the Rockefeller Foundation, Division of Social Sciences.  相似文献

Monitoring one’s own study processes accurately is important in self-regulated learning. This study compared a treatment (N = 45) and comparison class (N = 39) on the effects of monitoring exercises and feedback on calibration and test performance over a 16-week undergraduate course. Path analyses revealed a significant influence of the intervention on class performance, calibration, and self-efficacy. The results suggest the appropriateness of integrating distributed metacognitive exercises in class content and the fundamental role of monitoring ability in performance-based course outcomes and self-efficacy.  相似文献

Mental toughness can be conceptualised as a set of attributes that allow people to deal effectively with challenges, stressors and pressure. Recent work has suggested that it may be a valuable construct to consider within educational settings. The current studies explored the associations between mental toughness and educational transitions. Study 1 examined the relationships between mental toughness and concerns about moving to a new school in 105 children aged 12–13 years of age. The results revealed significant relationships between several aspects of mental toughness, but particularly confidence in abilities, and children’s concerns. Study 2 examined the relationships between mental toughness and adjustment to university in 200 undergraduate students at various stages of their course. The results revealed a role for several aspects of mental toughness; commitment, control of life, control of emotion, confidence in abilities and interpersonal confidence. The results are discussed in terms of implications for educational practice. It is suggested that measures of mental toughness could be used to identify individuals who may benefit from additional support during transition to a new school or to university, and that future research should explore the potential benefits of mental toughness training.  相似文献

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献
