新大纲、新教材比原教学大纲和教材,知识容量更大,知识面更宽,理论联系实际更紧密,能力要求更高,而课时却比原来少,这就对教师和学生提出了更高的要求.传统的教学模式不可能解决这个矛盾,只有优化教学过程,用新的教学方法,突出目标教学,才能提高课堂教学效益.为此,我们做了初步的探索和尝试. The new syllabus, the new textbook, has a higher knowledge capacity and a wider knowledge base than the original syllabus and textbook. The new textures are more knowledge-intensive, more practical and relevant in theory, have higher ability requirements, and have fewer hours than before. This puts higher demands on teachers and students The traditional teaching mode can not solve the contradiction.Only by optimizing the teaching process, using new teaching methods and highlighting the target teaching can we improve the efficiency of classroom teaching.Therefore, we made a preliminary exploration and try.
