This study investigates the relations between teachers’ attitudes towards persons with intellectual disability (ID), in-service training on ID, and prior contacts with persons with ID. A sample of Canadian elementary school teachers (N?=?118) completed the Attitudes Toward Intellectual Disability Questionnaire, which measures cognitive, affective and behavioural components of attitudes towards persons with ID. Correlational and multivariate regression analyses were performed. Frequent contacts with persons with ID and experience of including a child with ID increased the likelihood of reporting prior positive contacts with persons with ID. In turn, this was associated with less discomfort towards persons with ID and more willingness towards interactions. In-service training on ID was related to better knowledge of rights and capabilities of persons with ID. Experience of including a child with ID in general education classrooms increased the likelihood to report feeling competent in teaching children with ID, which predicted more willingness to include children with ID. 相似文献

AbstractThis study has a twofold objective: to analyse and compare the phonological processes in a sample of Spanish children with hearing loss, both with a cochlear implant and with a hearing aid, with a group with normal hearing; and to determine whether there are differences between the participants with a cochlear implant and with a hearing aid in the frequency and nature of the phonological processes. The sample is made up of 168 participants, eight with hearing loss (four with an implant and four with a hearing aid) and 160 with normal hearing. Samples of spontaneous speech were collected and transcribed using the tools from the CHILDES project. For the analysis, the phonological processes paradigm was adopted, evaluating phonological development based on normative error rates. The participants with a hearing loss show slower phonological development in terms of phonological processes, along with atypical processes. Furthermore, the participants with cochlear implants committed more phonological errors than those that wear a hearing aid. The implications of the results are discussed, and it is recommended that auditory stimulation should be done early in children with hearing loss regardless of their technical aid. 相似文献

This study explores the attitudes of future professionals working with students with disabilities towards four exceptionality groups: persons with deafness, with paralysis, with mental retardation (MR) and with delinquent behaviour, and specifically examines how deafness is perceived in comparison with the three other groups. Undergraduate students' (N=177) attitudes towards the four groups were tapped using a semantic differential scale referring to the cognitive, emotional and behavioural components of attitudes. Participants' degree of contact with people with disabilities was also reported. Results indicated that attitudes towards people with deafness were more positive than those towards the other three groups. Attitudes towards persons with paralysis were more positive than towards persons with MR and with delinquent behaviour, except when personality was considered. Emotional reactions and behavioural tendencies towards persons with delinquent behaviour were the most negative. Contact with people with disabilities had significant but low correlations with some aspects of the attitudes towards people with MR and paralysis. In general, the results of this study suggested that deafness was perceived as a physical disability and not as a social phenomenon. They also demonstrated that attitudes towards people with disabilities are a function of the particular disability condition and are multidimensional. 相似文献

本研究主要运用相关分析法及个人访谈法对来源于高职院校三大类学生的归因倾向、学校环境、兴趣水平、焦虑水平、学习策略水平、动机水平、动机行为、自我效能感水平分别与他们的自我效能感水平、兴趣水平作了相关分析。结果发现:三类不同学生归因倾向、学校环境、兴趣水平、焦虑水平、学习策略水平、动机水平、动机行为、自我效能感之间两两相关。对厌学者而言,自我效能与学习策略、动机行为达到非常显著的相关,与兴趣水平达到显著的相关,与学校环境存在不显著的负相关。兴趣水平与焦虑水平、自我效能达到非常显著的相关,与学校环境达到显著相关,与归因存在负相关。对次厌学者而言,自我效能与学习策略达到非常显著的相关,与动机行为达到显著相关,与学校环境、归因倾向呈现低等程度的负相关。乐学类学生的自我效能与动机行为产生了显著的正相关,与学校环境、归因方式产生低度负相关;他们的兴趣水平与动机水平、焦虑水平、自我效能、动机行为产生了中低度相关,与归因、学校环境、学习策略产生了中低程度的负相关。 相似文献

Difficulties with social communication may present challenges in gathering data from individuals with autism in research. To encourage individuals with autism to participate directly in research, methods that allow for autistic symptomology should be considered. An online forum was developed to enable adolescents with autism to share their social experiences. Ten female adolescents with autism, aged 12 to 19, engaged with the forum over 12 weeks. Questions were posted weekly and data were collected on the frequency of participant responses, quality of responses, and participants' engagement with each other. Data indicated that the frequency and quality of participants' responses were high, and participants' engagement with each other facilitated the introduction of new topics. The online forum was an effective tool for adolescents with autism to have direct participation in research. It offers promise in future studies as a practical research tool that accommodates the social communication challenges of individuals with autism. 相似文献
