XI. Feedback（教学反思）（教学反思） 本节课是人教版新目标九年级全册第八单元第二课时，主要围绕情 态动词表示推测这一用法来展开教学活动的。教学视频导入能够很 快过渡到新课学习中来，学生易于接受。我采用了任务型教学和情 境教学法，使学生掌握了本节课的主要语言知识，训练了学生的听 力水平，增强了语言交际能力。加强了学生的情感价值观教育，让 学生学会用心用脑，大部分学生参与课堂活动的积极性较高。不足 的是，对学生的所学知识巩固练习较少，师生互动不够活跃。希望 在今后的教学中我会继续努力，做得更好。 附练习： 1.-Whose dictionary is this? -It _ be Jacks.
