有效教学是开展教学活动的应然追求,实现有效教学需要教师在课前下足工夫。在进入课堂之前,教师若能扎扎实实对教材、对学生、对教法多“磨”一些,那么学生在课堂上也能多收获一些,课堂教学也会更有效一些。因此,教师应当研磨文本,深钻文本之“髓”;明晰教学目标,准确把握目标之“脉”;钻研教学设计,精心设计教学之“络”。 Effective teaching is the proper pursuit of teaching activities, to achieve effective teaching teachers need to work under the foot. Before entering the classroom, if teachers can solidify teaching materials and students and teach them more, they can also gain more in class and classroom teaching will be more effective. Therefore, the teacher should grind the text, drill deep into the text “marrow”; clear teaching objectives, accurately grasp the target of “pulse”; study teaching design, well-designed teaching “network.”
