ABSTRACT:Chemistry is a discipline based on experiment, chemistry experiments as an important role to stimulate students' interests, train students' capabilities and improve the quality of teaching quality. The paper with the students in Wenlan high school, third junior middle school in city of Mengzi and grade of 2009, 2010, 2011 in my school as investigation object of the research, combined with the data about some areas, understand the present situation of middle school chemical experiment teaching and its effects on students ' experimental ability. Survey results show that: (1) Most of the students of chemistry have a strong interest in learning, but due to the pressure of studies, students do less. (2) The school lab teachers weak students experimental skills and the normative, is relatively poor. (3) Teachers' improper arrangement of chemical experiment, students operate independently of experimental opportunities, resulting in students ' lack of ability and so few students are students' exploring ability to explore and practice the chemical phenomena in the life, does not use chemistry to solve life's problems. (4) Most students think of chemical experiment in middle school to now experimental ability was a great help, is important. These findings make several recommendations for improvement chemical experiment teaching in middle school: (1) Improve the laboratory facilities and management. (2) Changing attitude and understanding of the chemistry experiment teaching between teacher and students. (3) Stimulate students ' interest in learning chemistry experiments (4) Strengthening students for lives in the observation and research of chemical phenomena.
