新课程教学是以学生主动参与、乐于探究、交流与合作为新学习方式,以教师作为教学的组织者、策划者、引导者为新教学思想,以问题教学为新生物教学模式的中心。问题在生物教学中起着穿针引线的作用。教师只有充分认识问题教学在实践中的重要作用,通过创设问题情景,培养学生问题意识,鼓励学生大胆质疑、科学探究,养成自主学习的习惯,勇于探索、创新,才能顺利实现教学目标。 The new curriculum is based on the active participation of students, willing to explore, exchange and cooperation as a new way of learning, with teachers as teaching organizers, planners and guides as new teaching thoughts and problem teaching as the center of new biological teaching modes. The problem plays a role as a needle lead in biology teaching. Only by fully recognizing the important role of problem teaching in practice, teachers can achieve the goal of teaching smoothly by creating problem scenarios, cultivating students’ problem awareness, encouraging students to make bold questions, scientifically exploring and cultivating the habit of independent study, and bravely exploring and innovating.
