浅谈在三角函数教学中数学思想的渗透

数学思想主要包括:符号与变元表示的思想,集合思想,对应思想,数形结合的思想,化归的思想,对立统一的思想,整体思想,函数与方程的思想,分类讨论思想等.本文以三角函数为例,归纳了在教学中几种数学思想的渗透,体现了数学思想在解题中的重要作用.     

说课的灵魂在于交换思想

只说不评的说课是没有多大实际意义的,也是一种不负责任的说课。因为这样的说课所呈现的思想始终维系着原有的思想,唯有对说课给予评说,才能呈现评课者的思想,从而拥有两种思想。说课就应该是说出你的思想,提出我的思想,寻求更好的思想。说到底,说课就是交换思想。交换思想是为了丰富思想、提炼思想和创新思想,那么,教师就应该树立起说课就是交换思想的理念,需要明白说课的灵魂在于交换思想,从而通过说评双方互动而切切实实地交换思想。交换思想,就是交换教学思想,凝聚教学智慧;交换科研思想,提升科研能力;交换理论思想,提高理论素养。     

海德格尔对思想的追问——以《关于人道主义的书信》为例

在《关于人道主义的书信》中,海德格尔从行动的本质出发,对思想进行了追问。思想是存在的思想,思想是存在让予之思,思想和存在是统一的。但是在柏拉图和亚里士多德那里,随着存在的被遗忘,思想已经技术化,思想已经丧失了自身,思想已经不再是思想。基于这种状况,海德格尔走向了寻找思想的道路,他企图回到思想的源头,让思想摆脱技术座架的束缚,让思想承担起思想的任务。     

在初中数学教学中渗透数学思想方法

目前初中阶段,主要数学思想方法有：数形结合的思想、方程思想、转化思想、分类讨论的思想、整体思想、化归的思想、类比的思想、函数的思想,用样本估计总体的思想等。下面是我自己的几点体会。     

让数学思想成为提升学生素养的动力源

在中学数学教学中,加强学生对数学方法的理解和应用,以达到对数学思想的了解,使数学思想与方法得到交融的有效方法。初中阶段,主要数学思想方法有:数形结合的思想、分类讨论的思想、整体思想、化归的思想、转化思想、归纳思想、类比的思想、函数的思想、辩证思想、、方程与函数的思想方法等。     

渗透数学思想方法的三个教学环节

<正>数学思想是指人们对数学理论和内容的本质的认识,数学方法是数学思想的具体化形式,实际上两者的本质是相同的,差别只是站在不同的角度看问题。强调指导思想时,称数学思想,强调操作过程时,称数学方法,通常混称为"数学思想方法"。小学数学中常见的思想方法有:对应思想、类比思想、假设思想、比较思想、符号化思想、转化思想、分类思想、数形结合思想等。那么,在数学教学中渗透数学思想方法,必须抓住哪些主要的教学环节呢?     

英国教育思想演进的历史轨迹及特征

英国教育思想从文艺复兴时代到20世纪下半叶先后出现过九个思想流派,即人文主义教育思想、绅士教育思想、空想社会主义教育思想、科学教育思想、古典教育思想、功利主义教育思想、民众教育思想、新教育思想和分析教育哲学教育思想。英国教育思想演进历程表现出明显的四个特征:英国人追求完美教育的历程,有一条隐形的人文主义思想主轴,教育思想的演进与社会发展进程相吻合,教育思想在批判、创新和传承中演进。     

高职工程力学教学中应体现的几种思想

在工程力学的教学过程中,需要体现出诸多的思想。与生产实践相关的如学以致用、安全第一的思想,经济的思想,实验和标准的思想;与认知规律相关的如从基本点出发的思想,简化的思想,微积分的思想,层层深入的思想,类比学习的思想,具体问题具体分析的思想,抓主要矛盾、忽略次要矛盾的思想。多年的教育教学实践证明,通过将这些思想引入课堂,能端正学生的态度,提高学生的认识水平。     

试论商鞅的霸权思想

商鞅是战国时期先秦法家思想的著名代表人物,他的霸权思想主要体现在耕战思想、法治思想和君主集权思想上。其中,耕战思想是霸权思想的首要准备;法治思想是霸权思想得以实现的重要保证;君主集权思想是霸权思想的核心。商鞅的霸权思想是战国时期历史特殊环境的产物。他的思想有历史局限性也有其指导意义,要取其精华弃糟粕,对它批判地继承并能够开拓创新。     

中学概率统计中的数学思想及其教学

Exploring the Relations between In-service Training,Prior Contacts and Teachers’ Attitudes towards Persons with Intellectual Disability

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.     

A multidimensional study of special education students' attitudes towards people with disabilities: a focus on deafness

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.

Late phonological development in Spanish children with bilateral hearing loss / Desarrollo fonológico tardío en niños españoles con pérdidas auditivas bilaterales

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.

Values of endoscopic ultrasonography for diagnosis and treatment of duodenal protruding lesions

Objective: The diagnoses of patients with duodenal protruding lesions are difficult when using conventional examinations such as computed tomography (CT) and conventional endoscope etc. Thus, we investigated the clinical value of endoscopic ultrasonography (EUS) with miniature ultrasonic probes on the diagnosis and treatment of duodenal protruding lesions. Methods: Patients with duodenal protruding lesions who were indicated for EUS were examined by EUS with 12-15 MHz miniature ultrasonic probes and double-cavity electronic endoscope. According to diagnosis of EUS, those patients were indicated for biopsy and treatment received biopsy, endoscopic resection or surgical excision. The postoperative histological results were compared with the preoperative diagnosis of EUS. Those patients without endoscopic resection or surgical excision were periodically followed up with EUS. Results: A total of 169 patients with duodenal protruding lesions were examined by EUS, of which 40 were diagnosed with cysts, 36 with inflammatory protruding or polyp, 25 with Brunner's gland adenoma, 19 with ectopic pancreas, 17 with gastrointestinal stromal tumor, 12 with extrinsic compression, 12 with minor papilla, 6 with lipoma, 1 with adenocarcinoma and 1 with lymphoma. After EUS examinations, 75 patients received biopsy, endoscopic resection or surgical excision respectively. The postoperative histological results of 70 patients were completely consistent with the preoperative diagnosis of EUS, with 93.33% diagnostic accuracy. The results of follow-up with EUS indicated that duodenal cyst, Brunner's gland adenoma, ectopic pancreas, gastrointestinal stromal tumor and lipoma remained unchanged within 1-3 years. No related complications occurred among all patients that received EUS examinations. Conclusion: EUS is an effective and reliable diagnostic method for duodenal protruding lesions.
