Polymer chemistry is a basic specialized course for the major of Material Science and Engineering

because it touches many scientific disciplines and is vital in fields such as plastics and synthetic fibers ; paints and adhesives; and even biomedical applications. Synthetic fiber and polymeric hollow fiber membrane are the characteristic researches of Tianjin Polytechnic University

which both require solid knowledge of polymer chemistry. Therefore

students' activity is important

beside teachers' efforts in curriculum planning and preparation. In order to promote students' self-learning

homework were elaborately designed and assigned to attract students' interests

improve teaching effectiveness and urge students to spend more attention on this course. Through different afterschool works

students can easily master basic disciplines

overcome difficulties and apply theories to practice. Investigation on junior students showed that various afterschool works were helpful for improving their study interests and scores.
