一、问题背景随着新课程改革的深入,如何进一步落实新课标,切实提高教学质量,是每一个教师要直接面对的问题。高一化学是整个高中阶段的重点。高一化学学的都是必修,高二、高三学的就是选修了。必修是能否学好高中化学的关键,是之后学习选修的基础。必修中涉及的内容相对高一学生来说都是新的,是未知的。对高一学生来说,他们仅仅在初三阶段很短、很匆忙地学习了一些化学知识,没有形成相对系统的化学知识,也没有养成学习化学的习惯。因此,高中化学难教、难学已经成为一个不争的事实,这不仅仅是教学 First, the problem background With the deepening of the new curriculum reform, how to further implement the new curriculum standards, and effectively improve the quality of teaching is that every teacher should directly face the problem. High school chemistry is the focus of the entire high school. High school chemistry are compulsory, sophomore, junior high school is elective. Compulsory is the key to learning chemistry in high school, is the basis for elective learning. Required compulsory content is relatively high for a student are new, is unknown. For the first year students, they only learned very shortly during the first three stages of chemistry, did not form a systematic chemical knowledge, and did not develop the habit of learning chemistry. Therefore, high school chemistry difficult to teach, difficult to learn has become an indisputable fact that this is not just teaching
