解几何图形中的函数问题,关键是充分揭示题中所给几何图形的性质,借助这些性质来建立几何图形中相关元素之间的函数关系.在此过程中,要善于运用数形结合的思想,深刻理解函数性质与几何图形性质之间的关系,从而通过对函数性质的讨论来研究几何图形的性质.  相似文献

教会幼儿用几何图形表现物体,表现自我,能促进幼儿智力和能力的发展,有利于良好的非智力因素和道德品质的培养。我们在中班开展了此项教学活动,分三个阶段进行。第一阶段:认识几何图形1、通过实物或图片让幼儿观察几何图形的外形特征,认识边、角间的关系; 2、用讲故事的形式,让幼儿听后画几何图形,使他们能画出图形的基本特征; 3、观察用几何图形拼成的形象。通过这一阶段活动,使幼儿对常见的几何图形有比较清晰的印象,初步激发孩子们拼、画几何图形的兴趣第二阶段:学习用几何图形组成单个物体  相似文献

<正> 几何这门课程,是研究几何图形的性质、形状、大小和位置关系的科学。因此,在几何教学过程中,无论是讲、听、看、写、想、练都不能离开几何图形。弄清几何图形和它的性质的关系是几何教学中的首要问题。几何图形是第一性的东西,几何图形的性质是第二性的东西。几何  相似文献

几何图形的学习对于初步培养学生的空间立体观念和动手实践能力有重要意义。在农村留守儿童的几何图形教学过程中,教师要注重让学生自己动手,通过观察一些简单几何图形的特征认识基本图形,并慢慢过渡到复杂图形的学习。结合多年的教学经验,得出农村留守儿童学习"几何图形"的相关方法和策略,以期帮助农村留守儿童更好地认识几何图形学习的重要性,并帮助学生提高学习成绩。  相似文献

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

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

Maternal stress was assessed in mothers of children ages 8 to 11 years with learning disorders (LD). Age-, gender-, and IQ-matched children with reading disorders (RD; n = 31), children with nonverbal learning disorders (NVLD; n = 21), and typically developing control participants (n = 23) participated. Mothers of children with LD reported higher levels of stress, although the specific nature of the stress appeared to vary by disorder subtype: Mothers of children with RD reported higher levels of general distress, whereas mothers of children with NVLD reported higher levels of dysfunctional interactions with their child. The severity of the LD was strongly associated with maternal stress in the sample of children with NVLD but not in the sample of children with RD. In the sample of children with NVLD, the best predictors of maternal stress were 2 variables associated with the child: The lower the child's Performance IQ, the higher the level of maternal stress. Furthermore, the level of the child's internalizing symptoms was also a strong predictor of maternal stress in the sample of children with NVLD. In our sample of children with RD, the 3 best predictors were all variables associated with the mother, including her age, her level of reported psychiatric symptoms, and her overall level of social support.  相似文献

The social acceptance of a group of Zambian primary school children with intellectual disabilities by two groups of nondisabled children was examined. One group were in direct contact with the children with disabilities over a period of six months while the other was not. Nondisabled boys who had been in contact with children with disabilities had more positive attitudes than boys who had no direct contact, while no exposure effects were observed amongst girls. Gender differences amongst nondisabled children who had contact with peers with disabilities were not significant. Amongst the nondisabled children who had no contact with children with disabilities, girls had more positive attitudes than boys. The findings are preliminary, but offer directions for further research and have some implications for integrating children with disabilities into mainstream schools.  相似文献

Associations between children's social competence with peers and differential aspects of their teacher-child relationships were examined in a longitudinal sample of 48 4-year-old children enrolled in child care as infants. Toddler security with teacher was negatively associated with hostile aggression and positively with complex peer play and gregarious behaviors. Prosocial behaviors and withdrawing behaviors were associated with preschool security with teacher. Dependence on teachers as a preschooler was associated with social withdrawal and hostile aggression. Positive toddler teacher socialization was associated with higher perceived peer acceptance. Preschool teacher negative socialization was negatively associated with complex peer play, teacher ratings of hesitancy, friendly enactment, and accidental attribution and positively related to teacher ratings of difficulty.  相似文献

小学教师教学效能感与其归因反应模式的关系   总被引:2,自引:0,他引:2  
以155名小学教师为被试,探讨了不同教学效能感水平的教师对于不同特点学生学业失败后的反应模式。结果表明,在学生考试失败后,高教学效能的教师对于高努力的学生以及学习困难学生的生气程度较低,给予学生更多的奖励,预期学习困难学生在将来更容易失败;低教学效能教师对于高能力学生和学习困难学生的生气程度较低,给予学生更多的惩罚,预期低能力学生耷将来更容易失败。中教学效能教师的反应模式更接近于低教学效能教师。  相似文献

Abstract

This 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
