演示实验是小学科学教学必要的一种实验类型,广泛地应用于科学课堂教学。传统的教学:教师往往采取教师演示实验—学生观察—教师总结结论等方式,形成了教师做、学生看;或者教师讲、学生听;教师问、学生答的一种灌输式教学模式。这种教学模式的弊端显而易见:忽视了学生的主体位置;束缚了学生的思维。未来的教育是以人为本,着眼于发展的教育,显然传统的演示实验教学适应不了教育新形势的发展。
Demonstration experiment is an experimental type necessary for primary school science teaching and is widely used in science classroom teaching. Traditional teaching: teachers often take teachers to demonstrate experiments - student observation - the teacher concluded conclusions, etc., formed a teacher to do, students look; or teacher, students listen; teacher asked students to answer a kind of inculcating teaching mode. The drawbacks of this teaching model are obvious: ignoring the student’s main body position; binding the students’ thinking. Future education is people-oriented, focusing on the development of education, it is clear that the traditional demonstration experiment teaching can not adapt to the development of the new situation of education.
