教学情境,就是使学生从事学习活动、产生学习行为的一种环境或背景。它是传递信息的载体,能给学生提供思考的智力背景,同时也给学生提供了实践活动和情感体验的空间。生活,给人以无穷的体验、感悟和经验与知识的积累。因而生活中蕴涵着丰富的教育信息,以生活为载体,可以更自然地引导学生感受生活中的化学现象,进而提出问题、探究问题、解决问题,形成让学生体验探究、自主建构知识的这一符合建构主义学习理论的积极的学习方式,实现具有现代意义的“由生活走向化学、由化学走向社会”的学习。因而从生活出发,科学而有效地创设化学教学情境,是新课程教学的重要任务之一。
The teaching situation is an environment or background that enables students to engage in learning activities and generate learning behaviors. It is the carrier of information and can provide students with an intellectual background for thinking. It also provides students with space for practical activities and emotional experiences. Life gives people endless experience, sentiment, and accumulation of experience and knowledge. Therefore, life contains rich educational information and uses life as a carrier to guide students more naturally to experience the chemical phenomena in life, then ask questions, explore problems, solve problems, and form a way for students to experience and build their own knowledge. It is in line with the active learning style of constructivist learning theory and realizes the modern learning from life to chemistry and from chemistry to society. Therefore, proceeding from life and creating a scientific teaching situation scientifically and effectively is one of the important tasks of the new curriculum teaching.
