“以学生为主体,以教师为引导”是新课标提出的全新教学模式,即充分发挥学生的主体性,调动学生自主学习的积极性,而老师仅担任向导引导的角色。这一模式同样可在中学生物教学中加以应用,“我的课堂你做主”即为这一模式的产物。简要介绍“我的课堂你做主”的含义,然后探讨如何在生物教学中发挥学生的主体地位,以达到预期教学目的。 “Taking the student as the main body and the teacher as the guide” is a brand-new teaching mode proposed by the new curriculum standard, that is, giving full play to the students ’subjectivity and arousing the students’ enthusiasm for autonomous learning. The teacher only acts as a guide. This model can also be applied in middle school biology teaching. “My classroom is your product” is the product of this model. Briefly introduce the meaning of “My class is your master” and then explore how to give play to the students’ dominant position in biology teaching in order to achieve the expected teaching purpose.
