The fundamental task of China's education is quality education in a comprehensive way. The core of quality education is to develop a new education system. The new curriculum reform is a major task for promoting the development of students, teachers, evaluation of the education system to improve quality of school education. "Reform of Basic Education Curriculum (Trial)" clearly "too much emphasis on changing curriculum evaluation of the screening and selection functions play evaluation on the development of students and teachers to enhance the function and improve teaching practice. " Portfolio evaluation is due to the growth of student information, allow students to grow up happy experience, students play the main, innovative features to meet the new curriculum reform will become one of the evaluation. This paper literature, case studies and portfolio evaluation and experimental study of the application and high school chemistry students with the academic ties A theoretical and empirical research is aimed at Portfolio between the theory and practice to find a suitable point Portfolio Evaluation theoretical functions into full play, promote the development of students. hope that the students will learn to evaluate what impact use of the Portfolio. Through six essays have done in-depth description and analysis, research the background and significance; Portfolio Evaluation theoretical basis; Portfolio Evaluation and status at home and abroad; Portfolio Evaluation in high school chemistry teaching practice and exploration; Portfolio Evaluation of the preliminary results; Portfolio Evaluation Problems and Prospects. Is the author of more than a year in high school theory research, and 12 parallel classes in the six months of empirical research obtained on the basis of the case made by the rich. The author explored in these cases between theory and application portfolio assessment of a number of methods and techniques. and accumulated some experience, but also aware of Application Portfolio Assessment indeed play a role in promoting the academic performance of students. In other words, through the practice shows that the proposed specific Portfolio theory and the strategies are effective. Finally, Due to the time and other factors will be how the paper failed to collect material Portfolio, as well as the long-term use of a more orderly Portfolio evaluation of the impact of various aspects of the students come to the conclusion that they need to further their own research and follow-up of the experiments and research.
