多媒体是学生进入课堂的辅助引领者。常言说:“兴趣是最好的老师。”一节课,当学生进入课程教学后,能否保持较浓厚的学习兴趣,是上好这节课的基础,教师在上课时,除了充分发挥新教材的优势外,应用多媒体课件也成为引领学生走进知识殿堂的工具。通过课件把文字、图象、模型展示在屏幕上去创设情境、进行授课。这些直观形象,表现力和可控性强,绚丽的色彩,迷人的画面,极易吸引学生的注意力,激发学生学习的兴趣。从而引导学生有意、有序地观察,思考再结合教师的引导和讲解,把学生的注意力和兴趣都调动起来,使学生产生积极的学习态度,并以渴望和愉快的心情去学习,极大的提高学习的效率。
2、多媒体是教师传授知识的辅助者。课堂是学生学习的主阵地,是学生系统地学习科学文化知识场所,是师生互动,生生互动获取知识的主要场地,是学校教育教学的核心。如何在最短时间内使学生获取的科学知识,科学方法和技能,课堂教学仍然是学校教育教学的主要阵地,因而课件是采用多媒体教学的重要的内容,也是优合课堂教学的保证。课件反映信息量大、直观性强、节奏快、密度高,通过图形、文字、动画、声效来刺激学生身体各方面的反应,为提高教学效率提供了重要保证。它可以把抽象的概念和过程直观化,活化了教学内容,激发了学生的兴趣,收到了良好的教学效果,成为学生学习知识的辅助者。多媒体课件的使用,能有效地弥补传统教学的不足,化抽象为具体,把难以理解的内容或不容易观察到的事物充分显示出来,调动学生的视觉直观功能,为突破难点创造出良好的氛围。多媒体中声音、动画等的多方面刺激及丰富多彩的直观形式,引起了学生感知的兴趣,激发了他们的学习动机。比如在科学课上,有些教学内容因为绝大多数学生都没有亲眼见过,教学难度比较大。以往教学时,教师往往是利用挂图进行讲授。现在使用多媒体教学,就可以通过视频展示来播放,来一个“现场直播”,每位同学都可以清晰地看到演示实验的整个过程。让每位同学都有实验的亲历感,强烈的刺激了学生的视觉感官,充分调动了学生的积极性与参与性,激发了学生学习科学的兴趣,大大提高了课堂教学效率,改善了教学效果。
第一,多媒体教学改变了传统教学中粉笔加黑板的单一、呆板的表现形式,通过图形、音频、视频、动画等的运用,从多方面刺激学生的感官,调动学生的视觉、听觉、运动等感官都积极参与思考,激发了学生的学习兴趣,降低了思维难度,增进了对知识的理解,使知识的传播变得浅显易懂,直观形象。
第二,多媒体教学使一些在传统教学手段下很难表达的教学内容或无法观察到的现象能生动、直观地显示出来,可以让学生在课堂上通过幻灯片迅速直观地接收到大量的相关资料,既避免了以前的空泛讲解同时又通过视觉听觉的刺激,加深了学生对所学知识的记忆和对问题的理解,提高了学生学习的积极性。
第三,传统教学中课堂知识的传播主要来源于教师的口授与黑板板书,这两者速度的局限性限制了课堂的信息含量,而多媒体教学可以在有限的时间大大增加课堂容量,提高了课堂效果。第四,利用多媒体课件教学,可以集中全体教师的智慧与教学经验,更好地展现教师的才艺和想象。教师在备课方面有好的方法、好的设计,在传统教学中,有时是无法做到的,而现在有了多媒体的运用,就能轻而易举地办成。
多媒体教学可以在课堂里更充分创设学习情境,节约教学时间,充分展示知识的建构过程,实现了教学知识在与抽象、静态与动态、过程与结果、有限与无限等各方面的互相转换。多媒体教学能有效突破教学重、难点,更好地满足学生对知识的需求,提高教学质量,增进教学效果。为了更好地利用多媒体进行教学,我校对教师使用多媒体教学进行了多次的培训,使教师不但学会使用多媒体教学的一些基本技能,并且喜欢上多媒体教学。在帮补互助中,一些教师学会下载课件和制作课件,通过资源共享和成果分享,使教师赏到了使用多媒体教学的甜头。通过使用多媒体教研活动,创造了我校使用多媒体教学的氛围,激发了教师们使用多媒体教学的热情和积极性。
总之,多媒体教学给我们提供了一种学生主动参与,师生互动、协同学习的良好环境,使教学的重点由单纯的传授知识、技能、技巧转向开发学生的智力,培养学生的能力和创造力。多媒体教学的优点是显而易见的,多媒体进入日常课堂教学无疑是一个必然的发展趋势。在课堂教学中出现的不理想情况,不是多媒体技术的问题,而是理念上、使用方法上的不当而引起的,应将多媒体与课程教学进行整合,抓住其切入点,扬长避短使其发挥更大的作用。

随着经济社会的发展,科学技术的进步,多媒体已做为一种辅助教学技术进入中小学校,进入教室课堂。作为农村学校,多媒体教学在课堂中的应用,不仅能拓展学生的视野,更能激发学生的学习积极性。作为一名农村学校教师,我们应该积极探索适合农村实际教学情况的多媒体教学手段,发挥其积极的作用,更好地为农村教育教学服务,通过几年的探索,我认为要在农村做好多媒体教学工作,要把握好多媒体教学的以下几个方面:
常言说:“兴趣是最好的老师。”八年级学生一开始想学好物理的求知欲很迫切,但这种好奇心和迫切情绪毕竟是短暂的,当他们进入课程教学后,能否保持较浓厚的学习兴趣,是他们能否学好物理的关键.为使学生能自然地、比较平稳地踏上学习物理的轨道,增强对物理的学习兴趣,引言课就尤为重要。为上好这节课,我除充分发挥新教材的优势外,应用多媒体课件也成为引领学生走进物理知识殿堂的工具。通过课件把文字、图象、模型展示在屏幕上去创设情景、进行授课。这些直观形象,表现力和可控性强,绚丽的色彩,迷人的画面,极易吸引学生的注意力,激发学生学习的兴趣,从而引导学生有意、有序地观察,思考再结合实验,把学生的注意力和兴趣都调动起来。学习兴趣会使学生产生积极的学习态度,并以渴望和愉快的心情去学习,能使大脑的功能,极大的提高学习效率。使物理学习有好的开端。
学生学习的主阵地是课堂,课堂是学习系统的科学文化知识,提高科学素质的主要渠道,它是学校教育教学的核心,如何在最短时间内使学生获取更多的科学知识,科学方法和技能,课堂它是集中学生为一堂,教师精心组织和讲授,学生互动的场所,所以课堂教学仍然是教学的主要阵地,因而课件是采用多媒体教学的重要的内容,也是优合课堂教学的保证。而物理是一门自然学科,由实验和理论两部分组成。为更好的学习和掌握物理知识和方法,课件反映信息量大、直观性强、节奏快、密度高,也集了圆形、文字、动画、声效来刺激学生身体各方面的反应,为提高教学效率提供了重要保证。它可以把抽象的物理概念和物理过程直观化,活化了教学内容,激发了学生的兴趣,收到了良好的教学效果。也成为学生学习物理知识的辅助者。具体作用如下:
1、弥补传统教学的不足
多媒体课件的使用,能有效地弥补传统教学的不足,化抽象为具体,把难以理解的内容或不容易观察到的事物用媒体充分显示出来,调动学生的视觉直观功能,为突破难点创造出良好的氛围。例如,八年级上册第三章第五节《显微镜和望远镜》一节,由于条件限制,望远镜的结构及其作用学生不(宜理解,我通过课件展示,学生从直观上更易理解,激发学生的学习兴趣。
2、信息容量大
利用多媒体课件可以做到高密度的知识传授,增大信息量的优化处理,减少了教师绘图、板书、画表的时间,大大提高了课堂教学效率。图形虽然不是语言,但比语言更直观和形象,比语言包容的信息量更大。物理与人类的生产,生活关系非常密切,物理知识的应用非常广泛,利用多媒体可以在有限的授课时间内使学生尽可能多的了解物理知识的具体应用,拓展学生视野,为学生探究课本以外的知识,提高学生自主学习能力提供了条件。例如:在讲授初中物理教材中“探究凸透镜成像的规律”时,为了能让学生充分了解课本中的有关凸透镜成像的规律的基本内容,我利用课件的播放让学生边讲边学边实验,让学生对凸透镜成像的规律有比较全面的了解和体会。
3、多媒体教学体现了学生的主体作用
多媒体中声音、动画等的多方面刺激及丰富多彩的直观形式,引起了学生感知的兴趣,激发了他们的学习动机。例如:初中物理教材中的“连通器和船闸”,教学难度比较大,特别是船闸,因为绝大多数学生都没有亲眼见过,教学难度更大。以往教学时,教师往往是利用船闸挂图进行讲授。由于挂图缺乏动态效果,讲解费时又费力,且教学效果仍不理想。通过下载的课件,把船只从上游经过船闸驶向下游的整个过程用电脑动画形式模拟出来。效果会很好。上课时先让学生观看下述动画:某船处于某河的上游,正准备通过船闸驶向下游;船闸的上游闸门拉起一些,上游的水通过闸门下部流到闸室内,闸室里水面逐渐升高,直到和上游的水面保持相平;上游闸门打开,船从上游经闸门驶入闸室;关闭上游闸门,将下游闸门拉起一些,闸室里的水通过下游闸门流到下游,闸室里的水面逐渐下降,最后和下游水面相平;下游闸门打开,船从闸室经闸门驶向下游。教师在演示课件的过程中应不失时机地提出问题:
a、船闸是连通器吗?整个船闸相当于几个连通器?
b、上游闸门拉起一些时,水从什么地方流到什么地方?为什么?上游和闸室的水面最终处于什么状态?
c、在下游闸门拉起一些之前,为什么要先关闭上游闸门?
d、下游闸门拉起一些时,水从什么地方流到什么地方?为什么?闸室和下游的水面最终处于什么状态?
学生只要应用前面学过的连通器的知识对上述问题进行分析,就能较好地理解船闸的教学内容。这样使用视频展示来播放,来一个“现场直播”,每位同学都可以清晰地看到演示实验的整个过程。可见使用视频展示台与演示实验组合教学,让每位同学都有实验的亲历感,强烈的刺激了学生的视觉感官,充分调动了学生的积极性与参与性,激发了学生学习物理的兴趣,提高了课堂效率,改善了教学效果。
复习课内容学生大多是了解的,但需要归纳、整理使之系统化,从而形成知识网络结构。按照传统的教学方式上复习课,往往是“老师讲,学生听”。老师讲得口干舌操,学生听得昏昏欲睡。这种单调乏味的教学模式最后往往收效不大。复习课的课件的应用,既.增大了课堂容量,又提高课堂教学效益。它不仅拓宽了教学的信息面,而且显示在学习过程中,由单纯的听觉或视觉获取知识,变为视觉听觉同时使用,最大限度地刺激学生感官,使课堂效率大幅度提高。例如,章末复习时,通过知识结构展示知识点,然后讲解典型例题,再做例题。这样通过丰富的教学表现力和感染力,突出了教学的重点,解决了教学的难点,收到较好的教学效果。
多媒体辅助教学的作用是无限的,应用范围是广泛的,开发的潜力也是无穷的,但是由于农村条件的限制,对于多媒体教学的使用也从在一些弊端:
1、多媒体课件较单一,多是下载的现成课件略为修改,具有局限性。
2、多媒体教室的原因,上课要经常性的维持纪律。
3、现代学生较懒,多媒体上课学生一味只听,而不做笔记,形成短时记忆。
多媒体教学作为一种重要的教学手段已越来越凸现它的优越性了。但如何真正运用好媒体,发挥它的真正的辅助教学功能,还有待于继续探索、研究。

常言说:“兴趣是最好的老师。”1年级学生一开始想学好数学的求知欲很迫切,但这种好奇心和迫切情绪毕竟是短暂的,当他们进入课程教学后,能否保持较浓厚的学习兴趣,是他们能否学好数学的关键.为使学生能自然地、比较平稳地踏上学习数学的轨道,增强对数学的学习兴趣,引言课就尤为重要。为上好这节课,我除充分发挥新教材的优势外,应用多媒体课件也成为引领学生走进数学知识殿堂的工具。通过课件把文字、图象、模型展示在屏幕上去创设情景、进行授课。这些直观形象,表现力和可控性强,绚丽的色彩,迷人的画面,极易吸引学生的注意力,激发学生学习的兴趣,从而引导学生有意、有序地观察,思考再结合实验,把学生的注意力和兴趣都调动起来。学习兴趣会使学生产生积极的学习态度,并以渴望和愉快的心情去学习,能使大脑的功能,极大的提高学习效率。使数学学习有好的开端。
学生学习的主阵地是课堂,课堂是学习系统的科学文化知识,提高科学素质的主要渠道,它是学校教育教学的核心,如何在最短时间内使学生获取更多的科学知识,科学方法和技能,课堂它是集中学生为一堂,教师精心组织和讲授,学生互动的场所,所以课堂教学仍然是教学的主要阵地,因而课件是采用多媒体教学的重要的内容,也是优化课堂教学的保证。而数学是一门自然学科,由实验和理论两部分组成。为更好的学习和掌握数学知识和方法,课件反映信息量大、直观性强、节奏快、密度高,为提高教学效率提供了重要保证。它可以把抽象的数学概念和数学过程直观化,活化了教学内容,激发了学生的兴趣,收到了良好的教学效果。也成为学生学习数学知识的辅助者。具体作用如下:
多媒体课件的使用,能有效地弥补传统教学的不足,化抽象为具体,把难以理解的内容或不容易观察到的事物用媒体充分显示出来,调动学生的视觉直观功能,为突破难点创造出良好的氛围。
利用多媒体课件可以做到高密度的知识传授,增大信息量的优化处理,减少了教师绘图、板书、画表的时间,大大提高了课堂教学效率。图形虽然不是语言,但比语言更直观和形象,比语言包容的信息量更大。数学与人类的生产,生活关系非常密切,数学知识的应用非常广泛,利用多媒体可以在有限的授课时间内使学生尽可能多的了解数学知识的具体应用,拓展学生视野,为学生探究课本以外的知识,提高学生自主学习能力提供了条件。例如:在讲授初中数学教材中“探究凸透镜成像的规律”时,为了能让学生充分了解课本中的有关凸透镜成像的规律的基本内容,我利用课件的播放让学生边讲边学边实验,让学生对凸透镜成像的规律有比较全面的了解和体会。
多媒体中声音、动画等的多方面刺激及丰富多彩的直观形式,引起了学生感知的兴趣,激发了他们的学习动机。例如:初中数学教材中的“连通器和船闸”,教学难度比较大,特别是船闸,因为绝大多数学生都没有亲眼见过,教学难度更大。以往教学时,教师往往是利用船闸挂图进行讲授。由于挂图缺乏动态效果,讲解费时又费力,且教学效果仍不理想。通过下载的课件,把船只从上游经过船闸驶向下游的整个过程用电脑动画形式模拟出来。效果会很好。上课时先让学生观看下述动画:某船处于某河的上游,正准备通过船闸驶向下游;船闸的上游闸门拉起一些,上游的水通过闸门下部流到闸室内,闸室里水面逐渐升高,直到和上游的水面保持相平;上游闸门打开,船从上游经闸门驶入闸室;关闭上游闸门,将下游闸门拉起一些,闸室里的水通过下游闸门流到下游,闸室里的水面逐渐下降,最后和下游水面相平;下游闸门打开,船从闸室经闸门驶向下游。教师在演示课件的过程中应不失时机地提出问题:1、船闸是连通器吗?整个船闸相当于几个连通器?2、上游闸门拉起一些时,水从什么地方流到什么地方?为什么?上游和闸室的水面最终处于什么状态?3、在下游闸门拉起一些之前,为什么要先关闭上游闸门?学生只要应用前面学过的连通器的知识对上述问题进行分析,就能较好地理解船闸的教学内容。这样使用视频展示来播放,来一个“现场直播”,每位同学都可以清晰地看到演示实验的整个过程。可见使用视频展示台与演示实验组合教学,让每位同学都有实验的亲历感,强烈的刺激了学生的视觉感官,充分调动了学生的积极性与参与性,激发了学生学习数学的兴趣,提高了课堂效率,改善了教学效果。
复习课内容学生大多是了解的,但需要归纳、整理使之系统化,从而形成知识网络结构。按照传统的教学方式上复习课,往往是“老师讲,学生听”。老师讲得口干舌操,学生听得昏昏欲睡。这种单调乏味的教学模式最后往往收效不大。复习课的课件的应用,既.增大了课堂容量,又提高课堂教学效益。它不仅拓宽了教学的信息面,而且显示在学习过程中,由单纯的听觉或视觉获取知识,变为视觉听觉同时使用,最大限度地刺激学生感官,使课堂效率大幅度提高。例如,章末复习时,通过知识结构展示知识点,然后讲解典型例题,再做例题。这样通过丰富的教学表现力和感染力,突出了教学的重点,解决了教学的难点,收到较好的教学效果。
多媒体辅助教学的作用是无限的,应用范围是广泛的,开发的潜力也是无穷的,但是由于农村条件的限制,对于多媒体教学的使用也从在一些弊端:
a、多媒体课件较单一,多是下载的现成课件略为修改,具有局限性。
b、多媒体教室的原因,上课要经常性的维持纪律。
c、现代学生较懒,多媒体上课学生一味只听,而不做笔记,形成短时记忆。
多媒体教学作为一种重要的教学手段已越来越凸现它的优越性了。但如何真正运用好媒体,发挥它的真正的辅助教学功能,还有待于继续探索、研究.

“音乐教育不是培养音乐家,首先是培养人”。作为基础音乐教育的实施者,我们音乐老师的任务不仅仅在于教唱几首歌,而更重要的在于培养学生对音乐的兴趣爱好,提高他们的审美能力。这里最重要的是如何教的问题,不单是一两节课要上的如何精彩,而是要长远发展和整体去规划,小学音乐课课时并不多,我们更应该懂得根据我们学生的实际,运用科学的方法,让学生对音乐课保持渴望的激情,让音乐真正走进学生心里,启发学生感受音乐的美,进行想象和美的再创造,以达到育人的目的。
下面是我本人在这个学期进行音乐教学或参加教研活动后的一些感悟。
1、结合校本培训中的“和美课堂”继续落实“评价美”、“追求美”。
每节课我们都要组织学生对课堂进行评价,好的评价不仅要求评价本身具有语言美、听觉美,更要注重评价是否建立在促进师生共同发展的基础上。特别是教师对学生及课堂的评价,非常重要!例如:二(2)班的刘旭阳、方佳锋;二(1)班的梁天放;二(3)班的纪晓洁、刘秉萤等。这些学生上课都非常好动,个性很强!以前上课总觉得他们好想存心在捣乱似。你在学生面前批评他们只会起到反作用,我们老师首先要多关注他,每节课尽量安排他发言或帮忙做一些事情,不失时机地鼓励、表扬肯定一下他们。即使学生老毛病重犯,也不要在课堂上粗暴地训斥他们,而是婉转,上课还要注意那些问题,他们还是会有很大的改变的!最成功的案例是刘旭阳同学,在听音乐的时候上很有自己的思想和见解,当有些同学走路不安份的话,他也会适当评论几句“他们边走边跳还说话,既不安全,也不文明,不美!当然,老师同时尊重和体现学生个体的差异,教学设计要尽量满足学生的生活体验与需求,激发其主体精神,才能促进每个孩子最大可能的发展。
2、在知识能力的发展方面,由于我们的课时有限,不可能每一课都让学生背唱的得“滚瓜烂熟”。那我就抓知识点获一些重点,考虑到以后学生会学到曲式结构、五声民族调式、大小调式、唱谱和以后吹牧童笛做准备。我二年级要求他们背唱《小星星》《五声歌》曲谱;三年级背唱《左手右手》《捕鱼歌》的歌谱、编节奏;六年级牧童笛增加民族音乐的份量。主要是为下一步的学习做好铺垫,发现真的很有实效。
本学期,为了迎接11周,区教研室员胡老师的下校听课课,我的那一节《野兔饿了》的研讨课,经过了长达一个多的精心准备,虽然离教研员的要求还有差距,但科组的多次集备、试教,反复的打磨最后也确实上出了成效。记得最后一次试叫教我拿了蔡老师的一年(1)班来上,虽然一年级不能像二年级一样一节完成全部教学设计的内容,但一节课下来一(1)班的学生也能掌握四分休止符的用法了。在此我还要感谢蔡老师他们那些听课老师给予我很多有效的教学建议,引起我本人对教学方式改变的一些思考。通过这次学期的教研,二年级的学生把四分休止符和旋律进行的方式这两个知识点牢牢掌握了,我就感觉很有“磨出实效”的感觉。
现场观摩学习是让我们提高更快捷径。只要能调到课,不管路途多远,我们也一定会去争取观摩学习的机会。第十六周周五,在昌乐小学听了两位老师”关于奥尔夫教学法在六年级欣赏课的运用”的结题报告与示范课。这次听课让我们得到了很好的启发,就是小学音乐欣赏中,特别高年级阶段如何让学生去参与课堂教学,更好达成教学目标,使之成为“有效参与”的问题。我们都感觉很有收获和提高,这对于我们今后上好高段的音乐欣赏课真的很有启发,通过学习可以“借用实效”。
蔡老师13周在我们学校展的区欣赏研讨课《铜管乐器家族》。教研员为了让这次实地教研真正达到让大家共同提高的目的,评课时:让听课老师分成小组先进行讨论,然后让每个小组派代表轮流上台发言。首先,每位听课的老师都给予了蔡老师很高的评价:如:教学目标明确,能有效达成;教学环节很完整,教师思路很清晰,有条理,能很好的调控课堂;多媒体做的很好,教学资源丰富;备课认真,准备了很多与该课堂有关的音频、视频,丰富了教学内容。然后,很多小组又对本节课的设计提出了很多可以改进和提升的建议,这些建议不单是给蔡老师所提,其实对我们每位听课的老师都很有参考作用。如:在欣赏中,能否把乐器的音色与动物相结合?还有老师提到:可以设计体态律动多让学生参与,展示所听到的音色,听到小号的演奏时,请你举起双手按节奏拍手,听到圆号的演奏时,请你扭扭你的腰肢等等。还有胡老师提到的,用人声来模仿小号的声音,小号:dada da 长号du du du ;大号:beng beng beng ;圆号wu wu wu ,这些很实用的建议让我都把它记下来了,很有用!所以我称为“听取实效”。
这个学期快结束了,我感觉没有白忙!所有的辛苦和付出换来了上述的一些积累,可以说这些积累在今后的教育教学中都是非常实用、实效的。

目前应用广泛的课件制作软件powerpoint发挥着举足轻重的作用,简称ppt教学。所谓ppt,即用于设计制作专家报告,教师授课,产品演示,广告宣传等的电子版幻灯片制作的演示文稿,可通过计算机屏幕或投影仪播放。
ppt之所以成为目前课堂教学中应用最多、最广的课件制作软件,是因为与其他软件相比,具有如下优势:
1、制作课件简单易学,且在windows环境下,ppt是创建演示文稿最方便的工具,并且支持视频和声音,可在演示文稿的幻灯片中地插入表格、图象、声音、文本文件等多媒体信息。便于呈现教学内容和设计活动,使课堂教学更加生动有趣。
2、制作的课件节省了传统教学中的板书时间,可以根据需要增加课外知识和课堂补充。且在课堂应用中,用ppt所制作的课件操作简便、修改方便,课件的共享性强,易形成一个教学课件资源库,方便所有教师选用,并根据具体情况适当增删,以求使课件发挥最大功效。
3、powerpoint通过超级链接实现交互,具有一定的交互性,适合制作对动画要求不高的演示课件。即使不懂太多计算机应用的普通教师,也可以利用网上图片,动画等现有资源,从而制作出符合教学特点的课件。
作为初中英语这门课,教材内容极其贴近学生现实生活。而且学习一门语言,关键在于应用。只有多说多练习才能把所学内容内化成一种能力。了解学生的需要,创造贴近生活的情境,让学生融入到用外语交流的氛围之中。适当增加外国风俗习惯,扩大学生的视野,缩小母语对外语的负面影响。突出英语教学重点和难点,重视双基,以求提高学习效果和学生能力。在愉快的氛围之中完成学习目标,英语教学变得不再枯燥无味,也不会成为现代中学生的负担。
那么如何充分发挥ppt在制作课件中的优势?本人结合自己制作课件的经验和教训,以及听课和阅读他人课件的感想,除根据教学需要,优选插入视频、声音、图片、图表等多媒体信息以外,在进行课件的精心的设计和组织课堂过程中,还应注意做到以下几点。
(一)、充分利用ppt并与黑板板书相结合
在传统的课堂教学中,作为一堂优质课堂,教师除了运用生动的语言、灵活的方法、直观的教具和较多的训练外,还需要设计出简明扼要、生动直观的板书来体现教学重点,通过板书来呈现教学内容和流程,使课堂教学更加系统,便于突出教学重点。而依照顺序依次放映幻灯片,对所学内容很难形成系统的认识,很难准确把握所学内容的内在联系,不能形成一个明确的学习思路,进而不利于启发学生思维,培养学生能力,更不便于学生课后复习。
(二)、ppt设计应更重视教学目标与过程,并非愈简洁愈好
为了设计效果,往往大家认为应该插入一些装饰图,背景选的漂亮一些,插入的声音变换多一些。制作者的心情可以理解,可是花哨的设计虽然吸引了学生的眼球,却更多分散了学生的注意力。现在越来越多的制作者开始认识到制作课件应该“返璞归真”,我们的任务是让学生在愉悦生动的课堂中学到教学目标所要求的内容,我们的教学是有目的性的。在吃透教学目标和内容的前期下,应该思考怎样的流程能够让学生更容易地获得知识,怎样的活动设计可以最大程度的锻炼学生能力。设计的幻灯片应当宁简勿繁,内容精辟,既要突出重点,根据实际需要加入必要内容,又要切合学生实际需要,并且便于学生复习掌握。
使用多媒体教学是否出色,不在于课件制作页面好坏,而在于课的设计和教师运用的效果,学生通过使用课件能否精确掌握重点加深印象,锻炼听、说、读、写和交际能力。因此,课件设计一定从深层次揣摩,不能停留在设计表面。
英语课堂,需要刺激学生感官、给学生以形象而生动的感受,激发学生学习兴趣,客观上要求应用动态的图片,以及音像、视频等影视片段。目前最简单的做法是,通过“超级链接”功能链接到存放在硬盘等之中的音像、视频等素材。所有这些都需要我们不断进行计算机应用技术的学习,不断提升自己的计算机应用能力,灵活掌握和挖掘ppt的插入功能,将动画、音像、视频等等多媒体信息应用到课件中,充分发挥ppt的优势。
另外,在制作课件中需要许多素材,可以在百度中搜索“图片素材免费下载”和“声音素材免费下载”,也可以在迅雷看看搜狗中搜索所学影片或fash动画。
总之,ppt在制作课件中发挥着很多优势,当然也存在着不少弊端,只要教师能抓住课程内容的重点,注重发挥ppt制作课件的优势,将课程内容以最适当最有效的方式传达出来,多反思总结,最简单常见的ppt完全可以做出很有效的课件,达到提升教学效果的目的。

多媒体教学管理室主要承担了多媒体教学管理工作,校区正在使用的多媒体教室包括教学楼110个多媒体教室,现教楼6个大阶梯教室和1个多媒体教学远程控制中心,其中多媒体控制中心兼顾了远程录播平台的维护和使用。目前,由于多媒体教室数量多、教室分布广、距离远、教学任务重、各多媒体教室使用频繁等情况,借助信息化校园,使用信息技术武装队伍,利用假期时间完成了普通教室智能化改造,实现了远程观看、录播、行为数据统计等应用目标。同时狠抓日常管理工作和设备维护,较好地保障了课堂教学和各类活动的开展,没有出现一起因管理不到位,造成课堂教学无法正常进行的情况,得到了学院领导和相关处室领导、老师的好评。
制定完善了《多媒体教学管理人员岗位职责》、《多媒体教学控制室管理制度》、《多媒体教学控制室值班人员管理制度》、《教室多媒体教学设备使用管理规定》、《学生专职多媒体管理员制度》、《勤工助学学生岗位职责》。以及制定了《阶梯教室多媒体设备领钥匙使用登记表》、《大四各区队多媒体设备领钥匙使用登记表》、《周五、周六、周日阶梯教室多媒体设备领钥匙使用登记表》、《多媒体设备故障登记表》、《教学视频监控管理工作签到表》。有了这些制度的建立,就能减少,甚至杜绝管理上的混乱。
(一)建立工作团队,强化主动服务意识。建立工作团队能使管理人员充分认识到多媒体教学管理工作的重要性,要具有强烈的事业心和工作责任感,才能全身心投入工作。由于技术性、专业性强,设备故障率高,还需要经常加班加点对设备进行维护,这就要求管理人员必须具有任劳任怨、不怕苦不怕累的工作态度,不计较个人得失,更要有主动热情的服务态度。除了认真完成学院xx年课堂教学任务xx节课多媒体教学设备保障外,积极协助人事处、宣传处、学生处、团委、各系部、函授部、师资科安排的各项活动。包括助学专业二学历、司法考试培训、中级英语口语培训、心里咨询师三级培训、学术讲座、各类团活动等共2520多场次。
(二)强化多媒体教学控制室值班人员的管理。坚持每周轮换制,一人一周,值班人员上午、下午上课前提前20分钟到岗,中午10:05、下午16:30下岗,值班期间不得擅自离开岗位。遇到报修故障,5分钟赶到现场处理故障,小故障当场解决,遇到大故障,先安排老师、学生到其他空教室上课,然后继续修理或汇报。
(三)坚持每天教学楼、阶梯教室多媒体教学设备保障巡查。坚持每天巡查制度,早上8:20上课,8:10开始巡查,下午1:30上课,1:20巡查。每天做到比上课老师提前10分钟到各教室巡查,每天课前巡查,能起到预防设备故障的发生,减少设备故障发生率,也能发现设备故障能及时处理,赶在老师上课前解决问题,保证了课堂教学顺利进行。这一做法深得老师的欢迎。
(三)成立学生专职多媒体管理员队伍。学生专职多媒体管理员现有人数100人左右,主要承担教室多媒体设备的使用、安全和设备的卫生管理。每天任课老师上课前20分钟打开多媒体教学设备,协助任课老师解决课堂上设备操作出现的问题,下课后及时关好设备,确保设备安全。在阶梯教室上课时,负责到控制室拿多媒体钥匙开设备,下课关好设备还钥匙,这项工作看似简单,其实很辛苦,还必须要认真。只要有一个环节出问题,都容易造成老师在课堂上无法正常进行教学,很容易出现教学事故。所以,每月会定期召开不同年级的多媒体管理员会议,加强管理和监督。
(五)加强勤工助学学生的管理。勤工助学学生由学生处选派,对他们做好思想教育和技术上的培训,主要工作是协助管理员老师做好日常的多媒体教学管理,负责阶梯教室多媒体设备的安全维护和卫生,协助管理员老师做好晚上的网络直播、电视录像播放工作,周末的课堂教学和各类活动。
(六)合理控制多媒体教学设备的使用。多媒体教学设备的主要职能,就是要保证正常的课堂教学,依据学院教学计划的安排,完成课堂教学任务。学院现有80个多媒体小教室、5个公安网教室、6个阶梯教室,数量多,教室分布广,距离远,给日常的设备维护带来了很大的不便。如果没有一个严格合理的管理制度,就会出现多媒体教室使用上的混乱,设备的损坏,正常的课堂教学无法保障。多次主动向有关部门的领导、相关人员请示协商,耐心解释,摆问题,讲道理,最终制定了《教室多媒体教学设备使用管理规定》,满足了课堂教学需要。
多媒体教室数量多,使用次数多,故障率高,维修次数频繁。在这种现状下,我们团队管理人员只有3人,克服人手少的困难,齐心协力,主动工作,随叫随到,热情服务,不怕苦和脏,确保了学院多媒体教室设备的正常使用,获得了领导和师生的好评。
(一)强化管理人员业务技能学习。掌握了pns远程系统的传输,功放声音软件的调试,教室多媒体控制柜里电脑、中控、功放、操作面板的连接,网络直播软件的调试,电视接收播放录像系统,电源控制和点对点控制的使用。
(二)加强多媒体教室硬件设备、软件系统的维护。每年硬件维修均量:更换鹅颈话筒约50个,更换功放8台,维修vga信号线10个,电脑4台,电视3台。软件维修:软件、线路、网络造成多媒体设备故障约600次。
(三)坚持日常维护常态化。每周都要对教室多媒体设备安全、卫生进行检查,周五下午,利用pns远程控制系统对80个多媒体小教室电脑系统软件进行更新升级,不定期对阶梯教室电脑软件更新升级,做好设备故障的维修记录。

计算机和网络是当今先进生产力的标志,其在教育领域的引入对传统的教育思想、教学内容、教学方法和课程体系产生巨大的影响。传统教育“以教师为中心、以课堂为中心、以书本为中心”的教学模式已不适应于新课程体系的需求。为培养高素质的创新人才,我们在生物化学教学中引入多媒体课件教学模式,经过3年的教学实践,得到了非常好的效果,通过多媒体教学,使难于理解的生化机理通过图象、图表、文字、数据与动画演示结合融为一体,直观地表现出来。激发了学生的学习兴趣,使学习变得轻松愉快,学习成绩得到了大幅度提高。
通过总结,我们认为,多媒体在生化教学中的特点主要表现在以下几个方面:
1 丰富的表现力
在传统的生物化学教学中始终离不开一本书、一支笔、一块黑板的模式,很多时间都花费在对抽象、难理解的概念性问题的讲解,在平时的教学中,学生的思维活动水平常常会逐渐下降,思维处于关闭状态,这并不是学生自身的问题,而是传统教学手段的弊端shy;shy;——枯燥、乏味。通过使用多媒体教学,使一些生化事件的时间顺序、空间结构和运动特征形象直观地展示出来,如蛋白质、核酸等大分子物质的结构、酶的作用机理等通过高清晰度图片的展示,使一些抽象的原理变得简单,使学生一目了然。学生对知识的掌握更加准确。由于多媒体在表达抽象的概念、复杂的变化过程和运动形式上比传统教学有着更强、更丰富的表现力,加深了学生对知识点的理解和记忆,收到了良好的效果。
2 交互性强
多媒体课件在生物化学教学中的引入,增强了教学过程的交互性,使单向的教学活动变为双向和多向的教学活动,可以通过学生的理解和意图,运用适当的教学策略,指导学生进行有针对性的学习。充分利用了信息量大的功能,为学生提供了丰富的背景资料,拓宽了学生的认识深度,通过对真实情景的再现和模拟,培养了学生的探索、创造能力。教学效果可以及时得到反馈,迅速发现学生学习中存在的问题,可以及时调整教学策略,加强学生在学习中的薄弱环节,提高了教学质量。
3 共享性好
我们将生物化学多媒体课件上网,为学生的课外复习提供方便,并进行网上学习指导和疑难解答,拓宽了教学范围,实现了区域范围的传送和教学,通过内部网络,实现与其它教师和同学共享。学生可以通过灵活方便的交互界面来操纵控制学习,从而提高教学质量。
我们从生物科学专业20xx级甲班20xx级乙班开始使用多媒体课件进行教学,与20xx级甲班的学习成绩进行比较,这三个班由相同的教师授课,对学期末的考试成绩进行分析和问卷调查,将结果用sas软件作统计学分析,统计结果见下表:

两种教学方法效果经问卷调查分析,sas软件统计结果为p<0.01,差异极显著(*)。大多数学生对多媒体授课教师基本满意,认为教师教学经验丰富,对多媒体教学很投入,能结合多媒体技术进行创新教学,充分体现了传统教学与现代化教学的优势互补。
多媒体在生物化学教学中的成功应用,是对传统教学的改进和提高,但对于生物化学教学而言,当前阶段有许多实验是计算机所不能取代的,它只是一种手段或工具。我们将继续总结教学经验,创新教学方法,推广教学成果,将传统教学的优势与多媒体教学的优势充分结合起来,更好地为生物化学教学做出贡献。

随着素质教育的普及,普通小学也纷纷开设了英语课程。小学英语的学习渐渐成为家长们经常谈论的重点话题,从识字卡片到英语磁带,从鹦鹉学舌般地哼唱英语歌谣到看英语动画片,教师和家长们几乎是绞尽脑汁让学生对英语发生兴趣。可是学生对这些恼人的英语单词偏偏是记了又忘,忘了又记。他们即便是使出浑身解数背下这些单词,会话又成了难关,真是愁死人。自从让人头疼的英语从中学下降到小学,小学的课堂也似乎变得愁云惨淡。
如今,教育领域兴起多媒体教学,小学英语教师似乎看到一线曙光,开始纷纷尝试使用多媒体的教学手段。自从多媒体进入英语课堂,教师惊奇地发现,学生变得爱学了,英语成绩也开始有了提升。
多媒体教学综合多种传达信息的方式:动画形式飞入的文字,让学生觉得文字也有了生命;悠扬悦耳的背景音乐,悄悄拨动学生那活泼好动的心弦;清新宜人的精彩画面,悄然传递着生命与智慧的信息……这些被多媒体赋予的充满神秘色彩的信息无不激发学生那与生俱来的好奇心,激发他们去模仿、去想象。多媒体把英语单词由静止的枯燥难学的文字变成具体可感的图文相衬的画面,而这些画面又往往不是孤立存在的,他们都处在一定的背景下,一定的会话里。这些单词变成一个个有意义有生命的实体,或者是某些言语的一部分,学生在领会会话含义的同时,也在不知不觉中记住了这些单词。
例如,教师在进行课文新授教学的时候,可以不用先把单词提出来,而是直接映现在课文的场景里。随着课文中人物的会话的展开,在旁边适当的位置上以提示的方式闪现出有关生词及注释。等学生听完整篇课文之后,教师可以将这些词汇领读一下,而关于这些词的用法的分析完全可以放在讲解课文的时候进行。教师讲解课文要求学生记忆典型的句型并背诵整篇课文,也就是让学生记住这些英语词汇的词法和句法。这样做的结果会是,每当学生看到或听到这些词,马上就会联想到与之相关的事物,其英语思维也就会更加顺畅。学生容易对有生命的东西发生兴趣,多媒体教学就是利用学生的这一特点,努力使课本上静止的景物和人物动起来,让学生在色彩斑斓的图像中捕捉到更为丰富的教学信息。
一个多媒体课件可以包含很多内容,从文字到声音到视频,只要是教师能够想到的、搜集到的,都可以成为多媒体课件的素材。另外,多媒体课件也具有开放性,很多课件随着教师教学的不同需要可以反复修改,及时补充新的内容,这样这些多媒体课件随时可以保持生命力。多媒体课件中的素材来自方方面面,如随书附带的cd、网络,或者是来源于生活,来源于师生的创作等。教师可以随时选取其中最能体现课文内容的部分来充当课件的素材。
例如,教师在引导学生观看视频录像的时候,要经常变换场景,变换人物,尽可能多地让学生在反复模仿的过程中适应各种不同的交际环境。教师在布置口语作业的时候,也要求学生根据自己的实际情况编排相关的会话。这样一来,学生在背诵会话的时候就会轻而易举,因为他们就是在诉说自己的事情,同时他们的英语应用水平也会得到提高。教师在进行英语习题练习的时候,也可以尽可能多地从不同方面对词汇或者是典型句型进行练习。通过反复练习,让学生在头脑中形成条件反射,形成做题规律。由于多媒体课件展示教学内容的丰富性,学生可以从多方面加深对课文知识的感悟,也就满足了他们的求知欲,满足了他们对于多种知识的渴求。学生上课也就会感到更有意思,从而加强他们把英语学好的信心。
在以往的英语教学中,教师最多是放一下英语磁带,首先让学生感受纯正的英语发音,然后是跟读录音,朗读课文。有的学生连文章的意思还不清楚,这让机械的跟读成了一种形式,在进行听力训练的时候,学生甚至是望着房顶去理解;有的学生如听天书,听了半天也没有效果。而多媒体教学则完全不同,人物的会话总是在一定的场景中发生,学生可以通过场景猜测会话人的意图。文字、语音、语境、注释的同时呈现,大大化解了学生对于课文的理解难度。
在上课的时候,笔者经常这样办:播放第一遍视频的时候,让学生通过语音和画面去感知,这时不出现文字;第二遍时出现英语会话的内容,让学生修正自己的感觉;第三遍的时候,出现汉语注释及重点词汇及句型的分析,教师进行讲解。之后就是学生跟读和背诵了。笔者把每一篇英语课文都作为英语听力材料来处理,这样更加强了学生对于课文的理解。这样多媒体教学无疑对学生进行了充分的听力练习,让学生的英语语音更加纯正。听得多了,学生朗读课文的水平也随之提高。另外,笔者经常要求学生在课上尽可能使用英语以锻炼他们的口语表达能力,课下也经常布置一些口语作业,让学生把学到的知识再说出来,无疑可以检测他们对英语知识的吸收程度,培养他们的英语实用能力。在学生诉说英语的时候,笔者往往不做太多要求,因为这样做会挫伤他们的学习积极性,只要他们能够把意思表达清楚就可以了。
多媒体教学也能促进学生写作能力的发展。在学生看完视频的时候,教师可以要求学生仿写一段;或者根据图中提示,完成某些句子或编写一段文章;等等。教师经常要求学生进行写作练习,并不断修改和点评他们的作品,让他们的写作水平得以提高。
多媒体教学要求教师具备多方面的知识,不管是音视频的编辑能力,还是课件制作软件的熟练程度、语言的组织能力等,每一个环节都是对教师提出挑战。有些内容并没有现成的素材可以利用,这时就需要教师亲自动手来制作。为了制作得更完美,教师还要学会一些动画制作及图像编辑的知识和技能。从素材的搜集、制作、归类,到课件的构思、编辑、修改、测试、发布,整个过程无不渗透教师辛勤的汗水。而要想让课件成功,更是需要反复地构思、修改。多媒体教学很精彩,其路程却很艰辛,因为每一个成功课件都是教师辛苦耕耘的结果。
学生经过多媒体教学的培养,兴趣提高了,眼界开阔了,对英语产生的为难情绪渐渐消失,英语口语也从笨口拙舌到能够流利地表达自己的意图,发生质的转化。这使英语不只是停留在课本上的东西,而成了学生头脑中的一部分。学生口语交际能力提高了,听读写的能力也随之提高,英语成绩也有了明显的进步。教师明显地觉得自己比进行多媒体教学以前,不管是专业知识面,还是自身的信息技术技能,都有了突飞猛进的进步,今天的自我再也不是昨天那个整天对着学生的试卷发愁的教书先生了。每一名教师都感到自己具备了编辑及导演的才能,在构思、编辑课件的时候,总会感到涌动着一种创作的欲望,每一个课件都是一个生命的载体,寄托着教师深切的希望。
从昨日的汗水到今天的收获,从今天的展望到明天的飞翔,多媒体教学之路经历了许多。在这前行的路上,教师要经常驻足思考工作中的得与失,以随时矫正前行的方向。多媒体教学在应用的过程中可能会出现种种的偏差,因此要随时做好反思以去掉其中华而不实的部分。

任课教师:王影所授班级:计算机班所在单位:保亭职校本学期,我从各方面严格要求自己,积极向其他教师请教,一直也在跟有经验的老师沟通,也,课前认真备课,结合学校的实际条件和学生实际情况,勤勤恳恳,兢兢业业,使得教学工作有计划、有组织、有步骤地开展,为使今后工作取得更多的进步,现对本学期教学工作作一个总结,希望能发扬优点,克服不足,总结经验教训,以促进教学工作更上一层楼。
1、备课时,做到a、认真钻研教材,对教材的基本思想、基本概念,每句话、每个字都弄清楚,了解教材的结构,重点与难点,掌握知识的逻辑,能运用自如,知道应补充哪些资料,怎样才能教好。b、了解学生原有的知识技能的质量,他们的兴趣、需要、方法、习惯,学习新知识可能会有哪些困难,采取相应的预防措施。c、考虑教法,解决如何把已掌握的教材传授给学生,包括如何组织教材、如何安排每节课的活动。
考虑到学生是第一次接触该课程,而此课程又属于应用型,所以,内容及学生的实际,设计课的类型,拟定采用的教学方法,并对教学过程的程序及时间安排都作了详细的记录,认真写好教案,尽量的详细,内容难度不能太大,其引用的案例应尽量的生动,而又含盖授课内容要点,每堂课都在课前做好充分的准备,精心制作ppt,并引用各种利于学生熟悉、感兴趣的综合实例,深入浅出地讲解较抽象的理论知识点。在每次课后都有针对当堂课的重点布置相应作业,课后及时对该堂课作出总结,写好教学周记,并认真按搜集每课书的知识要点归纳。
2、课堂上,组织好课堂教学,关注全体学生,注意信息反馈,调动学生的有意注意,使其保持相对稳定性,同时,激发学生的情感,使他们产生愉悦的心境,创造良好的课堂气氛,课堂语言简洁明了,克服了以前重复的毛病,课堂提问面向全体学生,注意引发学生学数学的兴趣,课堂上讲练结合,布置好课后作业。
在课堂上特别注意调动学生的积极性,加强师生交流。如上课时候注意提问、注意学生的反应,并根据其反应作出及时的回应。充分体现学生的主作用,让学生学得容易,学得轻松,学得愉快;注意精讲,突出重难点,所布置的作业也各有侧重点,这也有助于学生对知识的把握。
在开学制定教学计划时,虚心请教其他老师,制定出学期的教学大纲,把握重难点。在各个章节的学习上积极征求其他老师的意见,学习他们的方法。同时,多听老师的课,做到边听边讲,学习别人的优点,克服自己的不足,并常常邀请其他老师来听课,征求他们意见,改进工作。
每次课后,都有与课堂内容相关的练习作业。同时对学生作业批改及时、认真,分析并记录学生的作业完成情况,将他们在作业过程中出现的问题分类、总结、进行透彻的评价,并针对有关情况即使改进教学方法,做到有的放矢。
由于多媒体通信技术属于应用型和理论相结合的学科,不仅重视学生的理论知识的理解和积累,更重视学生的知识应用能力的培养,因此,学生对知识的融会贯通只靠课堂的时间是不怎么现实的,这就要求老师的课后辅导相当重要,学生在复习,再学习的过程中,会遇到各种各样的问题,有的不能理解的,有的理解有偏差的,为了对不同层次的学生进行相应的辅导,以满足不同层次的学生的需求,避免了一刀切的弊端,同时加大了后进生的辅导力度。其中对后进生的独到,并不仅限于学习知识性的辅导,更重要的是学习思想的辅导,要提高后进生的成绩,首先要解决他们心结,让他们意识到学习的重要性和必要性,使之对学习萌发兴趣。要通过各种途径激发他们的求知欲和上进心,让他们意识到学习并不是一项任务,也不是一件痛苦的事情,而是充满乐趣的。
在此基础上,再教给他们学习的方法,提高他们的技能。并认真细致地做好查漏补缺工作。
总的来说,针对理论课,由于绝大多数学生对于理论性较强的课程都有排斥心理,尤其是抽象、难懂的课程,老师在备课的时候就要花比平时多两倍三倍的时间和心思,从内容的重难点把握,到深入浅出的例子分析;从ppt的精心设计和多媒体教室管理软件相结合,到课后作业的认真布置,都容不得任课教师的半点马虎,只有做好了以上工作,在教学过程中学生才学得有兴趣、有收获;老师也教得愉快。另外,学生听课状态的及时把握及扭转,课后作业的批改和讲评也是理论课不能缺的环节。本学期,通过我对以上工作的认真对待,期末同学们也都获得非常好的成绩,这情况是我没有料到的,因为尽管平时有人旷课且不做笔记,经过教育后也没有好转,当我仍一直认为我给同学们复习好了后,大家在考试前肯定会认真复习和记忆,考试成绩应该不错的。有很多平时不认真的同学都取得了优异的成绩。
工作和生活是个积累的过程,是个付出与回报相对应的过程,我会继续努力,继续加油。因为在本学期的技能比赛过程里,计算机的同学已经用优秀的表现来回报我的辛勤努力了。我很满足,亦很幸福。

随着科技的进步,教育的发展,多媒体辅助教学,正在以强大的优势,改变着传统的课堂教学。特别是在小学语文教学中,合体运用多媒体辅助教学,能创设生动逼真,动静结合的教学图像,生动的教学气氛,充分调动学生的积极性,更好的激发学生学习的兴趣,为培养学生创新意识提供了良好的教学手段。因此如何发挥多媒体的优势,优化语文课堂教学,是我担任语文教学以来一直钻研的课题。以下是我在教学工作中总结的几点经验,拿出来与大家一起分享。
小学低年级的学生具有好奇、易动、乐于参与的特点,多媒体的表现手段正适应了他们这个特点,使学生们感到学语文课不再像以前所经历的枯燥和无味了。不断变换的屏幕形式、新颖的题型很大程度的提高了学生学习语文的积极性,激发、调动了学生的学习兴趣,使其产生强烈的学习欲望。
例如在教学《海滩上》时,文中的开头我播放了一群小朋友在海边快乐的玩耍的情景,他们有的用沙子堆城堡、有的在捡五颜六色的贝壳、还有的光着脚丫一边跑一边数着自己的小脚印……动画以播放,小朋友们一下子就被着快乐的场面所吸引了,激起了学生学习这篇课文的欲望。
字、词、句、篇是语文的经脉,而识字则是语文教学、阅读和写作的基础,是提高学生语文素养的基本要求,因此它是语文教学中的一项重要工作。然而汉子的数量多,难以识记,对于低年级的孩子,我们该如何让他们喜欢学习汉字又有主动学习汉字的愿望呢?在识字课堂教学中多媒体就充分的发挥了他的优势,在教学中我通过创设一种宽松、愉快的环境,使学生了与思维,勇于探索,尽快的、全身心地融入到识字教学过程中。
例如:在教学《祖国多么广大》时,我利用多媒体软件,把海南岛开满了鲜花;大兴安岭下着大雪;帕米尔高原的上空挂满星星和乌苏里江畔身披彩霞的景象一一呈现在孩子的面前,美丽的景色变化一下子吸引了孩子们的眼球,视线不知不觉随着景色的变化而转动,他们很想知道该如何称呼这些景色,这是,我出示了景色的名称“鲜花盛开、雪花飘洒、满天星斗、五彩朝霞”,这时孩子们能通过直接观看的景象,集中精神认字,从而提高了认字的效果,又大大提高了孩子们识字的兴趣。再如:在识字教学中,我们可以把生字新词做成红彤彤的大苹果长在枝叶茂盛的大树上,带领孩子们做摘苹果比赛的游戏,还可以利用多媒体展示生字书写的过程,既直观又形象,学生还很乐意学。
小学低年级学生的生活体验和观察实践活动比较少,着极大的影响了学生对课文内容的理解和重点知识的掌握。在这一点上我运用了多媒体教学所具有的得天独厚的优势,通过动画模拟、局部放大、过程演示等手段,是较复杂的、里生活比较远的、难以理解的内容变为直观、浅显、动态的感性材料,使学生易于理解和把握。
在教学《花篱笆》一课时,因为篱笆离我们现在的生活比较远,学生很难感受花篱笆的美丽和它所传递的人与人之间美好的情感。讲课时,我借助多媒体课件,营造了特定情境的动画:一座典型的农家小院,主人在四周插上了矮矮的竹篱笆,竹篱笆上开满了美丽的喇叭花,院子里面有一棵大树,大树底下有一群小鸡、小鸭在捉虫子,两个调皮的小孩把篱笆当成球网,开心的打羽毛球,东、西两院儿的大人隔着篱笆在拉家常;院子外面有绿油油的庄稼,还有五颜六色的野花,时而还有一两个路过的行人……看着这美丽和谐的画面,孩子们一下子就感受到了花篱笆的美丽,体会到了花篱笆带给人的亲切感。
观察是写好作文的基础,没有细致准确的观察,学生就不能话写清楚。因此指导学生观察就显得很重要。在教学的实践中,根据教学内容,选择相关的音像资料播放,打破了实践的界限,地域的阻隔,将食物展现在学生面前,而且能使该事物反复出现,加深学生对它的印象。例如在写秋天的景色时,我用多媒体播放丰收的秋天:有果实累累的果园,有金行色的麦田,有随风起舞的落叶……硕果累累的秋天展现在学生的面前,再配上欢快的音乐,学生有感而发,触景生情,不仅写出了秋天丰收的景象,还写出了对大自然的无比赞美热爱之情。
实践证明,只要合理的运用多媒体,就可以让它在语文的课堂教学中发挥巨大的作用。既可以活化教学内容,变抽象为具体,变静态为动态,又可以化难为易,促进学生积极主动的学习。作为一名新时代的教师,我会再接再厉,在今后的工作中继续探索,不断学习多媒体的技术,是多媒体辅助教学真正的发挥它的优势,以优化语文的课堂教学。

我们在制作多媒体课件时通过网络获取文字、图像、声音、动画、视频,等多方位信息用于课件制作,丰富了课件内容和表现形式。internet为教学提供了无所不有的信息,而英语教师利用internet为教学服务又具有天然的优势—— 无语言障碍,这样,使教学内容更丰富,教学方法更灵活,为英语教师的创造性工作提供了更多的思路和信息。在制作短文填空题专题复习课件时,我查阅了很多关于短文填空题教学方面的资料,从中精选了一些练习,然后归纳出解题方法和解题原则。在使用课件时,结合近年中考题型,指导学生了解短文填空题命题思路和题型特点,进而介绍解题方法和解题原则。没有网络资源,要做到这些恐怕不是件容易的事。
通过精心准备,教学中我们可以借助电脑、投影仪等先进的多媒体手段,向学生展示图、文、声、像相结合的丰富多彩的教学内容,在有限的时间内扩大课堂语言流量及容量,从而可以优化英语课堂教学,提高教学效果。在制作短文填空题复习课件时,我就精选了不同时态的文章学生自己发现并归纳做题的技巧,让学生对文章中各种词类的常见错误做到心中有数。最后,给出两到三篇短文指导学生完成,效果非常明显。一节课完成这么多的内容,这样的效果是以往的教学手段无法达到的。
教师在课堂教学中深入了解学生的心理特征和认识规律,运用多媒体技术创设悦耳、悦目、悦心的情境,可以使学生产生如见其人、如闻其声、身临其境的感受,催发出学生积极探索的情感,从而调动学生的学习兴趣。在短文填空题专题复习课件中,我用网上下载的flash英文歌曲导入,学生兴趣大增,领略了原汁原味的英文歌曲旋律,使原本显得枯燥乏味的复习课变得轻松有趣。同时,在课件中添加一些特殊的文字和图象效果,下课时再以一段美妙的旋律结尾,让学生带着愉悦的心情离开,留下了美好的印象。
备课是教师研究教材、制定教法、研究学生、制定学法的常见模式。多媒体参与的教研活动,既集中了教师的集体智慧,又锻炼了骨干教师,同时培养了青年教师。现在,我们与所有的英语教师共享多媒体资源,形成了一股浓厚的科研氛围。
应该说,多媒体教学系统以其独特的功能为我们创设了一个异彩纷呈的视听环境和良好的思维环境,能激发学生学习的情绪和兴趣,让英语课堂教学不再枯燥无味,优化了课堂教学,不再局限于教师所讲,不再拘泥于课堂。从而调动非智力因素,消除学习紧张感和焦虑感,提高学生学习的效率。自从运用多媒体辅助教学以来,我们不仅把它用于短文填空,在英语阅读理解和完型填空等复习专题上也做了同样的尝试,学生的综合素质得到了明显提高,激发了学生的创新意识和自主学习的意识,由被动接受变成了主动探究与获取,激起学生强大的求知欲,学习质量不断提高。
总之,多媒体技术在教学中的应用,给传统的教学方式带来了巨大的冲击,为教育的发展带来了机遇,但同时也带来了挑战。我们在教学的第一线深深体验到多媒体的优势给英语教学带来的活力。尽管如此,利用多媒体服务于教学还是一条漫长而修远的路,我们应努力提高自己的综合素养,不断摸索电教多媒体技术和课程整合的最佳结合点,使之更好地为教育教学服务。
随着信息时代的突飞猛进,书面阅读式的文化走入了多媒体的阅读文化,幼儿获取信息的渠道已不只是图书了,幼儿完全可以从符号、文字、图象、声音、动画等信息媒介中获取自己感兴趣的信息,早期阅读的范围在拓宽,早期阅读的意义更加深远,因而在培养幼儿阅读能力的过程中要加强多媒体中阅读内容的利用,既能激发幼儿阅读的兴趣,也是教育现代化的重要标志和发展趋势。
学习兴趣是学生获得知识,扩大眼界,丰富知识经验的最重要的推动力。但从幼儿年龄特征看,他们以无意注意占优势,需要一定数量和质量的刺激才能引起幼儿的注意,而在幼儿园阅读教学中运用多媒体技术综合运用形、声、色、光的效果,创设各种形象生动、灵活多变的学习情境和教学情境,虚拟现实,再现生活物景,把静态知识动态化,抽象知识形象化,枯乏知识趣味化,从而营造了轻松自然的学习氛围,唤起了幼儿的有意注意,诱发幼儿的情感共鸣,使幼儿在不知不觉中全身心地投入到阅读教学活动中,这不仅激发了幼儿的兴趣,陶冶幼儿的情操,还极大地增强幼儿的认识动力和能力,推动他们学习。
电脑多媒体具有鲜艳和生动的图像,动静结合的画面,其智能性的启发和引导,必然使孩子在学习过程中很有兴趣,并由此唤起高涨的学习情绪,幼儿的感觉、知觉、表象、记忆、思维、情感、意志等心理因素都能保持良好的状态,孩子的认知心理将得到发展和提高。多媒体软件中可以设计幼儿喜爱的各种情景,引发幼儿产生愉快轻松的情感体验,有利于激发幼儿形成积极健康愉快的情感。另外,计算机在调节幼儿学习情绪上也有较大的优势,当幼儿获得阅读操作成功时,计算机就会说出表扬的话"你真棒"、"你太聪明"、"太好了"等,或请可爱的小动物奖一颗五角星、一朵红花等,如果幼儿阅读操作错了,则会播放"你要努力呀",“没关系,请再想一想”等鼓励的话,这就迎合了幼儿的学习心理,从而使幼儿产生了浓厚的学习兴趣。
在传统早期阅读教学中通常通过几幅图片,几本书的教育方式进行,已经远远适应不了幼儿的需要了,而运用多媒体课件将课文的意境、内容、语言结合在一起,并以生动有趣的画面展现出来,极大吸引了孩子们的注意力,提高了幼儿学习的积极性,再通过生动的画面与多变的表现,将抽象的文字知识形象化、兴趣化,为幼儿创造了一个自由、宽松的语言环境,最后通过各种的形式让幼儿进行语言交往,使幼儿轻松完成了学习任务,真正体现了“乐中学、动中学、玩中学”这一观点,这样不仅让孩子感受到语言美的魅力,同时又发展了他们的观察力、想象力、表达能力。例如在学习《坐火车,真有趣》一课时,当有趣的画面一出现,立刻引起了幼儿浓厚的兴趣,老师的提问,立刻引起了幼儿的仔细观察,孩子们争先恐后地回答,老师简单归纳后,轻点鼠标,幼儿看着画面跟随轻柔的音乐朗朗读出。散文的学习,运用了5幅动画课件进行,向幼儿讲述散文的内容,启发幼儿对散文的理解,运用肢体动作来表现散文的意境美,这样给幼儿充分的想象,交流的空间。在此基础上,再让幼儿完整欣赏散文,他们很快就掌握了散文的内容,通过游戏让幼儿掌握了教学内容,密度适中,充分调整幼儿的视觉、听觉等多种感官,较好突破重点、难点,幼儿始终兴致盎然地进行学习,圆满完成教学任务,这无疑拓宽了我们的教学资源,优化了我们的课堂教学。
在计算机上把学过的儿歌、诗歌、故事制作成课件,图文并用,为幼儿朗读,激发幼儿的阅读兴趣。如:悦耳动听的朗读声将有助于孩子集中注意力,扩大词汇量,积累知识,丰富想象力,对孩子智力的开发、性格的塑造、爱好的养成、感情的丰富、情操的陶冶,激发孩子的学习兴趣。尤其我们利用计算机多媒体通过声音、图像等多种表现形式,使幼儿能对知识掌握得更加透彻、更加形象、有利于调动幼儿思维的流畅性、变通性和独特性,激发积极的思维能力和阅读能力,培养分析问题和解决问题的能力,从而有所发现,有所提高。美国教育家杰姆.特来斯说过:“听读是引导孩子阅读的有声广告。”因此,我们老师每天让孩子听读5到10分钟,这对于激发幼儿阅读兴趣是非常重要的。这种听读主要是以欣赏图片故事和其它文学作品为主要内容,如散文、故事等。幼儿在教师抑扬顿挫的朗读声中油然而生想读的愿望。听读的目的是让幼儿反复倾听成人那娓娓动听的朗读,并不断体验、品味。通过听读活动可以集中幼儿的注意力,丰富幼儿的词汇,激发想象,拓宽视野,萌发情感。尤为重要的是可以使幼儿逐渐领悟语句、结构和词义神韵,从而为广泛阅读打下基础。
幼儿时期是人生智力开发和品德形成的起始阶段,良好的观察讲述能力的培养对幼儿的心理发展和认知能力的形成具有重要的作用。多媒体对培养幼儿的观察力独具优势。
选择有教育意义的图片和动画片让幼儿观看,引导幼儿有序的观察,逐步积累经验。幼儿只有认真观察画面,才能理解画面内容,看后让幼儿把主要内容说出来,教师引导幼儿学会观察,并提出能引起幼儿观察的问题,以帮助幼儿理解画面内容,由浅入深地让幼儿观察“画面上有什么?”“他们在干什么?”还可以提出一些故事以外的内容来引导幼儿观。,在幼儿逐页观察画面并理解画面内容后,再引导幼儿有序地观察,理清思路,把握好故事结构。引导幼儿有序地观察,目的在于让幼儿积累阅读方面的知识,更重要的是让幼儿掌握阅读方法,懂得故事的内在规律,知道故事是按照“人物、地点、事件、结果”的顺序来发展的,使幼儿获得有序思维经验。幼儿在阅读中认识某些汉字时,能将图与字结合起来,有助于对一些汉字的理解,逐步积累幼儿的阅读经验,为幼儿独立阅读打下基础。
学龄前的幼儿的思维以具体形象为主要特征,抽象逻辑思维出现了萌芽,随着信息技术发展迅猛,改变着人们的学习、生活和思维方式。多媒体教学以它特具的新颖、趣味、直观和艺术性,使教学活动变的丰富、多媒体以其丰富的表现力,强大的交互性,深深地吸引着幼儿。我把故事、儿歌的内容在多煤体上制作成课件,制成幻灯片给幼儿提供阅读材料,图文并用。好容易吸引幼儿学习,激发了幼儿的阅读兴趣。通过形象的图象和文字,幼儿容易记住故事和儿歌的内容,所以让幼儿进行故事和儿歌表演时,幼儿很快就能把主要内容表现出来了。比如:我在上散文诗“七彩的风”时,把这个故事制成flash动画,图象、声音整合在一起,幼儿的注意力好集中,通过看一看,听一听,幼儿好容易记住了散文诗的内容,并能大胆地说出这首散文诗的内容。又比如:我在上故事《三只小猪》做了一个flash动画,在学习儿歌和创编儿歌时,在这有声有图象的情景里,让幼儿进行创编活动,比看图片的效果好多了,教师由传统的讲解者转变为教学活动的组织者、指导者,孩子由被动地学习转变为主动地参与学习了,语言表达能力也提高得好快,还认识了不少汉字。班中的部分小朋友,由于他们对我们组织的活动感兴趣,所认识过的汉字都已经记得,语言表达能力强,能看着图片的文字,有声有色地讲述故事,并能基本理解故事、诗歌的大意。
想象力如奔驰的骏马,在思维的天地里往来驰聘。想象力的丰富与否,直接影响着幼儿思维能力、语言表达能力的发展。如果在活动中适当借助多媒体手段培养幼儿的想象力,效果会很好。在教学活动《小羊过桥》中,我做了前半段故事的动画,“……小黑羊和小白羊分别在河的两边,河上有一条独木桥,他们两个都要过桥……”画面在此定格,接着会发生什么事情呢?请幼儿充分发挥想象。于是小朋友你一言,我一语,有的说:“他们两个谁也不让谁,后来都掉到了河里。”有的说:“他们会互相谦让……”孩子的思维就像插上了翅膀,在天空中自由地飞翔。
电脑多媒体技术在幼儿早期阅读课堂教学中起着不可估量的作用,恰当地运用电脑多教媒体手段即符合幼儿的认知心理规律,能促进幼儿的智力发展,同时还能优化幼儿园课堂教学结构,有效地提高教学质量。因此,利用电脑多媒体技术以图画读物为主,以看、听、说有机结合为主要手段,从兴趣入手,并萌发幼儿有话敢说、有话想说的氛围和情感,丰富幼儿阅读经验,提高阅读能力,发展孩子的想象能力、思维能力和表达能力。
