瑞士心理学家皮亚杰认为:儿童学习的最根本的途径应该是活动,活动是联系主客体的桥梁,是认识发展的直接源泉。根据心理特点,放手让学生在动手、动口、动脑的协调之中,进行自主探求知识的活动,可发展学生的认知结构。这就要求我们在教学中改变课堂教学模式,实行开放式教学,让学生自主地探究性学习。1.让学生尽可能去“想”。培养学生一个“敢”字,鼓励他们毫无顾及的尽情去想,合理的去想。如学《圆明园的毁灭》 Piaget, a Swiss psychologist, believes that the most fundamental way for children to learn should be activities.
