误区之一:耗时费力,制作嫌烦。多媒体课件的制作对教师提出了较高的信息技术素养要求。一是要求教师要会应用一些多媒体课件制作软件,如简单的Powerpoint,复杂点的Flash等;二是要求教师要具备一定的整合能力,会搜集、加工、处理、整合课件制作时所需的各类信息,会精心设计、统筹搭配,科学整合;三是要求教师要围绕学生学习兴趣激发、综合能力培养、思想觉悟提高恰当应用,巧妙应用。过“高”的要求与教师较低的信息技术素养形成了明显的反差,再加之多媒体课件制作费力大、耗时多、制作难,致使部分教师见“机”生畏,“烦”于课件制作。
误区之二:不择良莠,搞大拼盘。多媒体课件以其呈现方式多、信息量大、直观性强而在课堂教学应用手段中见长。于是,部分教师在制作多媒体课件时便不择良莠、不论取舍,凡是与其教学内容相关的各类图像、文字、声音信息均取而用之,不合逻辑的堆而砌之,搞大拼盘,将其“特长”发挥到了淋漓尽致的地步,反而适得其反。
误区之三:华而不实,“移情别恋”。好奇是学生的天性,可以使其插上想象的翅膀自由翱翔。多媒体教学课件中的一组动画、一个声音乃至一幅图片都可能带来学生遐想联翩。可是部分教师在制作课件时却恰恰忽视了学生发展的这一身心特点,反而竭尽全力在课件的呈现方式上求新求异求变化,力求字字有动画、帧帧有特效,处处与众不同,致使学生在听讲学习时要么应接不暇,走马观花,缺失思维,身心俱累;要么窥其一斑,移情别恋,思绪万千,身在曹营心在汉。
误区之四:应用失当,人随“机”转。多媒体课件只是一种优化课堂教学组织与设计的手段,而不是课堂教学的全部。然在教育教学过程中,部分教师自认为所制课件设计新颖、内容全面、环环相扣,所以在教学中就按照课件设计思路按部就班,层层推进,全然不顾学生的学情及所思所想,机械的点击,不停的放映,过于突出多媒体课件的作用,反而使教师缺失了教学的能动性、创造性和灵活性,教学中的机智、灵感闪而复失,教学之境浅入浅出,教学艺术的锤炼也便无从谈起。
误区之五:用完即毕,昙花一现。每一件多媒体课件从构思到设计,从选材到制作都融入了教师的智慧,渗透了教师汗水,是其勤劳和智慧的结晶。作为教师个人,应该将其收藏,以备后续使用;作为学校,应该指派专人负责,进行收集整理,作为一种现成的教学资源,把其共享,让更多的老师分享。然现实是部分教师用过即忘,既不注意修改完善,也不注意整理收藏,往往为了节省硬盘空间,提升电脑运行速度,便毫不迟疑的删除。这样,再美的课件,再好的结晶,也只能是昙花一现。
误区之六:强求使用,拗瓜不甜。它上之石,可以攻玉。网络丰富的课件资源为我们学习借鉴和使用提供了便利。然部分教师在使用网络上下载的课件时往往不加思索、不注意修改完善,便直接生搬硬套,反而使得课堂教学偏离了自己的教学设计,囿于别人的思想范畴,难于驾驭。再者,部分中小学为了督促教师熟练掌握和运用信息技术,便强化要求、细化制度、硬化指标,要求教师堂堂都要使用计算机多媒体课件服务教学,置教师课件制作水平、繁忙的工作实际以及教学内容于不顾,不但没有提高课堂教学的当堂效益,反而使得一些传统的好的教学用具也被束之高阁,派不上用场。
