本单元教学自评93分，表明教学目标达成度较高。整个单元教学回归教材，紧紧围绕

“谈论发明物”这一主题，由浅入深、由简单到复杂，从谈论日用品的发明史、食物、玩具、

运动到自己的小发明，教学活动形式多样，教学步骤步步递进、环环相扣，形成合力，从听、

说、读、写诸方面培养学生这一话题的表达能力。由于教学内容紧扣学生实际，学生积极投

入各项学习活动，勇于表达自己的真情实感。同时，在谈论发明物，特别是在谈论发明家的

发明过程中，体会到了观察力与创造力的重要性，了解世界上重大发明创造，树立了创新精

神。为了减轻学生课余学业负担，提高教学效率，教材所涉及的所有练习，包括增加的多个

写作练习都安排在课堂完成。就其成功原因主要在于，课前我们认真研读了教材，尽可能吸

取了与教材配套的《教师教学用书》提供的中英文教学建议，并结合学生的实际，从单元整

体备课，细化单元及课时教学目的，合理安排课时教学内容，并在尽可能多的预设教学活动

的前提下，关注课堂生成，随时根据学情调整教学活动，因而教学收到了事半功倍的效果。

但课后在不增加学生过重课业负担的前提下，如何指导学生复习、开展预习、课外阅读

等活动，尽快培养学生英语语感等方面还有待研究。
