所谓情境教学,即教师通过利用各种有效的教学资源,如多媒体、教材等使学生主动参与到学习中的一种环境模拟教学方式。它强调的是一种氛围,恰当、有趣的教学情境是激励学生自主学习的助推器,是保证教学质量的关键。因此,小学数学教师应当合理利用教学资源,创设教学情境,优化数学教学。 The so-called situational teaching, that is, teachers through the use of a variety of effective teaching resources, such as multimedia, textbooks and other students so that students take the initiative to participate in learning an environment simulation teaching. It emphasizes a kind of atmosphere, proper and interesting teaching situations are the boosters to encourage students to learn independently, and it is the key to ensure the teaching quality. Therefore, elementary mathematics teachers should make rational use of teaching resources, create teaching situations and optimize mathematics teaching.
