The Research On Errors Of The Periodic Law In Chemistry Exercises

By a series of literature review, collecting the students' exercises and interviews, this research focused on analysis of the situation that students make mistakes in the Periodic Law. In high school chemistry studies, there are many blind spots and errors.Based on the errors of the students' exercises, proposed the research inspiration for teaching.In interviews, we found that students who took attention and use of the errors in the exercises can often get better grades, and who didn't take the initiative of and the use of the errors in the exercises often have poor academic performance. The errors in the exercises, not only teachers' teaching resources, but also learning resources of students, which requires teachers and students to make full use of the errors in the exercises. In particular teachers should guide students building awareness of using the errors in the exercises, develop good learning habits.
