培养学生自主学习、自主探究能力问题,是新时期基础教育教育教学改革的重要内容之一。需要教师在具体教学实践中采取相应策略,妥善研究解决。一、创设问题情境,引导学生自主探究根据现代中学生发育特征和特点,积极在生物学科创设问题情境,使学生主动参与学习。让学生通过自学课本发现和提出问题。如在学习《输送血液的泵——心脏》一节时,学生通过观察课本中的心脏解剖图时会发现:心室壁比心房壁要厚,左心室壁比右心室壁要厚许多。那么,为什么会出现这种现象呢?
Fostering students’ autonomous learning and self-exploration is one of the important contents of the reform of basic education and teaching in the new era. It is necessary for teachers to adopt corresponding strategies in concrete teaching practice and properly study and solve them. First, create a situation context and guide students to explore independently According to the characteristics and characteristics of modern secondary school students, and actively create a problem situation in the biological disciplines, so that students take the initiative to participate in learning. Ask students to discover and ask questions through self-study textbooks. As you learn from the “Blood Pump - Heart” section, students will find that the wall of the ventricle is thicker than the wall of the atrium and that the thickness of the wall of the left ventricle is much thicker than that of the wall of the right ventricle. So, why is there such a phenomenon?
