In recent years, diversification of sources of rural middle school teachers, teachers ' professional qualities and also more uneven, and many young teachers lack expertise, competition consciousness and ability in the workplace also lead directly to the loss of students, affecting the social reputation of the school, to the construction and management of rural middle school teachers sounds the alarm. Therefore, in a certain sense, attention to professional growth of young teachers in middle schools in villages and towns, focus on the future development of rural middle school. According to yingde green Tang town middle school Township middle school young teachers professional development research subject research programme, we subject group in objective real, and science actual, and development need of principles, design survey questionnaire, full volume total 69 problem, main content is divided into three a part: first part: basic information second part: teachers professional development status, and is divided into eight a part: a, and teachers expertise and skills II, and teachers workload and burden three, and education resources and textbook using four, and research and teaching situation five, and The six teaching reflective behaviors of teachers, teachers ' learning and training in seven, teachers on the professional identity of eight, the leisure part teacher professional development of teachers through questionnaires, questionnaires, record computer processes such as statistical analysis, cost of the sky survey report. Second, the purpose of the investigation, methods and objects (a) the purpose of the survey the purpose of the survey is that real, comprehensive, fully understand our school (if there
