ABSTRACTIn the current study, two pools of 250 essays, all written as a response to the same prompt, were rated by two groups of raters (14 or 15 raters per group), thereby providing an approximation to the essay’s true score. An automated essay scoring (AES) system was trained on the datasets and then scored the essays using a cross-validation scheme. By eliminating one, two, or three raters at a time, and by calculating an estimate of the true scores using the remaining raters, an independent criterion against which to judge the validity of the human raters and that of the AES system, as well as the interrater reliability was produced. The results of the study indicated that the automated scores correlate with human scores to the same degree as human raters correlate with each other. However, the findings regarding the validity of the ratings support a claim that the reliability and validity of AES diverge: although the AES scoring is, naturally, more consistent than the human ratings, it is less valid. 相似文献

The present study assessed the impact that children with intellectual disabilities have on their mothers' self-esteem. It also examined the differences in self-esteem between mothers of children with intellectual disabilities and mothers of non-disabled children. The study sample consisted of 50 mothers of children with intellectual disabilities living in Central Greece and a comparison group of 50 mothers of non-disabled children. Two instruments were used for the data collection: (a) a questionnaire for biographic information and (b) an adaptation of the Culture-Free Self-Esteem Inventory. Results indicated significantly lower self-esteem for the mothers of children with intellectual disabilities. Moreover, the best predictor of maternal self-esteem in the disabled group was the size of the family. 相似文献

This study was designed to elicit the views and preferences of primary education students’ with general learning difficulties concerning different service delivery modes. The main areas to be investigated were: (a) their current educational provision, (b) alternative modes of provision and (c) the most appropriate provider (mainstream or special needs teacher) of educational support. The sample consisted of 95 students in grades 2–6 who voluntarily participated in the study. Interviews, including seven questions concerning students’ views on and preferences for different educational settings (regular classroom without additional support, resource room, in‐class support), were employed for gathering data. The findings clearly confirmed our hypotheses that: (a) students do hold preferences about where and by whom they should be taught, and (b) they do not unanimously prefer one service delivery mode over another. While the majority of the students preferred the resource room over the regular class, it is significant, at the same time, that almost one‐third of the participants preferred the regular classroom. Students’ preference for educational setting (regular classroom or resource room) was significantly influenced by their view of which setting provides more academic benefits. Regarding their preference for the most appropriate provider of support, the great majority preferred receiving help from the special education teacher. Given that in‐class support is not practised in Greek schools and none of the participants had any experience of systematic in‐class support provided by a special teacher, it was surprising to establish that almost one‐half of the students preferred to receive the additional support within the regular class. Students’ preference for a service delivery mode (pull‐out or in‐class support) was significantly influenced by: (a) their preference of educational setting (regular classroom or resource room), and (b) their views of which setting provided greater academic benefit. 相似文献
