Theory And Practice To Improve The Effectiveness Of The High School Chemistry Jobs

Concerning the senior high school education in Chemistry, the exploration of how to promote homework effectiveness is important for the cultivation of talents in new century, which is also a requirement of basic education curriculum reform. But an unfortunate reality in teaching is that some shortages also exist in the improvement of homework effectiveness. In view of this, the purpose of this thesis is to research on how to improve the effectiveness of Chemistry homework as well as students' initiative in doing homework and consolidating the knowledge they have learnt. It's also aimed at researching into the ways of developing students' ability in processing information, analyzing and solving problems, communicating and cooperating with others and lifelong learning.In the paper, we summarize the characteristics, standards of chemistry homework effectiveness and implementation principles. On the basis of practical teaching in chemistry in senior high school, we selects three typical cases, that is, ion coexistence, Avogadro's constant and the final comprehensive practice, to expound the attempt and exploration on how to deal with the details and links in time-limited exercise for daily class, evening class and the weekends.Combining individual interview with questionnaire, this thesis analyzes and ponders on students' intention, attitude, habit and difference in the process of completing the Chemistry homework, plus the ability to accomplish the task.The relevant materials collected in practical teaching prove that it is workable to carry out the exploration of the effectiveness of chemistry homework in senior high school, which is beneficial to both teachers and students. This thesis also reflects on the factors that influence the effectiveness in completing chemistry homework in senior high school.
