多媒体外语教学中生成问题的处理随着教学改革的不断不深入，多样化的教学手段日渐进入课堂。多媒体在英语教学中的使用除了直观地将知识以图像、声音、动画等形式生动地传递给学生之外，在很大程度上，它独特的传递视觉信息的设计会对学生产生一定影响。精心的预计会产生如期的生成常常指教师的教学按照既定目标实施成功了的东西，是针对教师的教学效果而言的。但在实际教学中，很多学生在多媒体课件情景的刺激和启发下，突发的一些想法、观点以及可能与本课无关的问题会被教师事先设定好的预设而埋没。案例：一位英语老师在一节英语课上，通过多媒体课件和学生分享了这样一个故事：一位老人被陌生人骗走了 1000 元，大病了一场，本课的目的是要告诫老人和学生不要轻易相信陌生人要学会保护自己。老师制作的 PPT 非常成功。其中有一个情景是老人被骗后，那种无奈，会很有无助的神请，确实令人潸然泪下。以下是课堂上师生之间的对话让人发人深思。T: Who should we scold and blame?(The teacher expected the answer is the thief or the people who cheated the old lady.) S1:Certainly we should blame the young guy who cheated the old lady. But I think we should blame more about the old lady’s children because they do not know how to protect their parents. T: Please focus on what the test is telling us,and try to think what the old people should do when strangers try to persuade them to believe something.S1( Murmuring ) Her son is not very good because he should have given another 1,000 Yuan to his mother,since the money could not be chased back. That could pervent his mother from suffering from her own fault.T:( Caring nothingabout the student’s answer, and continuing to ask anotherstudent)What do you think we should scold and blame and give your reasons?正如这个案列所示，如果学生接触到的是纯文本信息那么他们很可能会适应老师的问题促成教师预设中要生成的结果。但这种图文互动的效果生成了教师没能事先预设的信息。在教学中产生了一种意外的情境反应。所以我们应该思考这样的问题：1、有没有必要去估计这些意外的想...
