| The essence of the special topic study website is a system of special topic research and cooperated study which is based On the network resource. It offers lots of special topic resource and cooperated study instrument to learners under the network study environment ,to make learners choose and direct their tasks or designs of items. They themselves can collect, analyze and choose information ,apply knowledge to solve the practical problems. It emphasizes that learners solve the problems through their main exploration, research and cooperation ,So that it makes learners experience and understand process of exploring, improve learners practical ability of abtaining information, analysing information and polishing information ,and cultivating their creative ideas and information accomplishment .Math is an abstract of quantity and space formed in the human beings life .And geometry put its emphasizes on the exploration of space of things inner and inter .Geometry course is an important content in middle school teaching, which helps students grasp geometry knowledge and cultivate their thinking ability. It is significant to develop students' thinking in math .Students are easy to understand what they learn through multimedia and network, putting sources to rational use and designing software to turn the abstract to the visual. It is beneficial for the learners to get through teaching emphasizes and difficulties. Therefore, the positive design research of geometry teaching in the middle school under network environment has great significance to find a rational teaching model.The research are applied a way of the single factor and two levels, which design a teaching example—Interesting Mosnic under theory guide of construction and research. It selected classes six and seven, grade two Ping Zhuang Mining middles school,Yuan Bao shan district Chi Feng Znner Mvngolia, to try out.I draw a tentative conclusion after a month experiment and analyzing statistic data .1.Creativity:Thinking of the students is widen, aspects of thinking vary, they may find many new problems and gain many new results.2.Study interests: The combination of special topic study website and exploring teaching arouses student' enthusiasm, stir their interest ,to better excavate their potential and initiative study to improve teaching efficiently.3.Way of study: Create a comfortable for the students based on exploring teaching at the special topic website. Student' achievement is not knowledge accumulation, but improvement of creativity ability during their study process .At the same time, students can probe into study activities according their own choices. All in all, to some extent it means students develop a way of initiative study and exploring study.4.Information accomplishment :Students grasp the methods of using math instruments and relevant internet knowledge. On the other hand, students' ability of using information implement are greatly improved, as a result, they treat technology as their study means, which must play an important role at study and life in the future.
