上课伊始欣赏歌曲 《apple song》,欢快的旋律加上可爱的视频让学生快速融入英语学习的氛围中来,同时也开门见山迅速切入本课的主题——水果。 本课八个水果中除grape外,其它在三年级都已经学过,所以通过让学生说说自己喜欢的水果,让学生快速调动起已有的知识,帮助学生回忆和复习已学的水果单词。 利用课件创设水果远近的情景教学句型 “What are these?/ What are those?”,对比鲜明,易于理解。而 “these” “those”的发音是本课的教学难点,我引导学生从已学单词的发音来推断出新单词的读音,有效地突破教学难点。 |

语篇教学从整体入手,先让学生观看动画,了解Miss Li 要买的水果; 再让学生细读课文,找出每种水果各买几公斤,并适时教学How many kilos? 在学生理解对话的基础上,通过跟读、表演、配音等多种活动帮助学生巩固对话。 为了让购物语言更富有生活化的气息,在语篇拓展环节渗透教学了“…yuan a kilo. How much are they?”等句型。 |

克鲁姆说过,成功的外语课堂教学应在课内外创设更多的情景,让学生应用学到的语言材料。在教学完本课的知识点之后,有必要将语言延伸到文本外,在模拟的情景中活用语言。 创设有意义的购物情境,让枯燥死板的句型操练在充满浓厚生活趣味的实情实景中得以反复模仿与操练,使课堂充满“灵气”与“生机”,学生在轻松开心的游戏、活动情境中“情”、“景”交融,以“情”激“趣”,以“景”促“情”,对所学句型无疑留下深刻印象。 |
