在化学课程教学实践中,我对学习情境的创设进行了较多尝试。我认为,要创设有效的情境,应遵循以下原则。首先,课堂的不同时段,情境的侧重点也不同新课引入时创设情境要“趣”。在引入新课时创设一些有趣的学习情境,在课一开始就能抓住学生的注意力,浓厚的兴趣会使学生产生积极的学习态度,并以渴望和愉快的心情去学习、探究。例如在《燃烧和灭火》的教学中,我以两个实验引入新课。 In chemistry teaching practice, I made a lot of attempts to create learning situations. I think the following principles should be followed in order to create an effective situation. First of all, the different stages of the classroom, the emphasis of the situation is also different from the introduction of new courses to create scenarios to “fun.” Creating a few interesting learning situations when introducing new classes will help students catch the attention of the students at the beginning of the class. Strong interest will enable students to develop a positive learning attitude and learn and explore with longing and pleasant mood. For example, in the teaching of “burning and extinguishing fire”, I introduced a new lesson with two experiments.
