教学策略是指为了实现某一教学目标而制定的付诸于教学过程实施的整体方案,具体包括组织合理的教学过程,选择适当的教学方法和教学材料,制定切适的教学行为程序。通过执教《动物在生物圈中的作用》一课,笔者发现,合理使用教学策略,可以有效提高课堂效益。一、情境教学策略能帮助学生进行意义建构教学应该在和真实情境相类似的环境中发生。在真实情境中学习,一方面可以激发学生的学习兴趣,提高学生学习的参与度,另一方面可以促使学生对所学内容进行意义建构,提高学生知识迁移的能力。 Teaching strategy refers to the overall plan put into teaching process in order to achieve a certain teaching goal, which includes organizing reasonable teaching process, choosing appropriate teaching methods and teaching materials and formulating appropriate teaching behavior procedures. Through coaching “a class of animals in the biosphere”, I found that the rational use of teaching strategies can effectively improve classroom efficiency. First, the situational teaching strategies can help students to construct the meaning teaching should occur in an environment similar to the real situation. Learning in the real situation can stimulate the students’ interest in learning and improve their participation in learning. On the other hand, they can make students construct the meaning of the content and improve their ability of knowledge transfer.
