First, the problem raised Present students in the design of experiments, the description of the phenomenon of the test phenomenon, particularly prone to poorly articulated, incomplete description, non-questioning and other minor mistakes, resulting in the general chemistry of students unsatisfactory. The long-term existence of this phenomenon shows two problems: on the one hand it reflects that students’ ability of writing is not strong and their logic is poor; on the other hand, it reflects that teachers unilaterally emphasize the principle of knowledge in teaching, Training insufficient attention, inadequate means.
