| Thesis makes a practice explore about cooperative evaluation on the students’mathematic knowledge system by themselves in group.Having worked on the math teaching at middle school for four years,author have found that most students was lost in "highland phenomenon" and "solving problem stiffly" at the phase of reviewing.On the basis of teaching theory author expect to enrich the review pattern through cooperative evaluation,and create a favorable situation in which students and teacher communicate each other,in order that student could consummate their own mathematic knowledge system and construct common knowledge space in the activity of communicating,sharing.We believe students will be absorbed in the class,appreciate each other by evaluate in groups.And at the same time,students also realize the beauty of math,the power of class,the happiness of success.In order to achieve an end,and provide a practical cooperative evaluation model,author has read many papers about study theory,evaluation theory,and mathematic problem solving theory.On the basis of deep thought,author design a plan of cooperative evaluation and put it into practice in Zhicheng Middle School,Linxia,Gansu.At last I have some conclusion of this practice:First,every student makes progress by cooperative evaluation,and the growth range of excellent students and poor students is not more obvious than the students who are in average level.Practical data display that the student who are in average level acquire huge improvement,they make their own system more delicate by the cooperative activities.Second,the operative activities have different effect on students who are in different level.For the excellent students,the activities have an effect on their cognitive strategy,on study they focus on the connection of different knowledge points,the essence of every mathematic exercise problem,the transition of different topic,and emphasis on the detail and trap of the exercises.Through evaluation assessment,their knowledge systems become more comprehensive and reasonable.But for poor student,the activities affect their attitude to study and math,they feel more confident and happy under the help of the members of the group,they begin to tend to work hardly on the impact of the cooperative activities.On the basis of practice,analysis,and thought about theory,author has constructed a common framework of the cooperative evaluation of Students’mathematic knowledge system,put forward to the evaluation purpose,principle,standards.At the same time,I have expressed the general process of the cooperative evaluation activities systematically,summarize the special activity by using four key words "observe,point out,inquire,suggest".Most importantly,I assess the evaluation activities,under the standard of "having,able,daring,taking delight in",we have a estimate of the cooperative activities.Based on the above content,author provides a model which could be put into practice.I just expect that students can realize the important meaning of the mathematic knowledge system,and the students could expand the math into real life,look at the world in the sight of math,analyze the real problem in life using mathematic thought and go through a happy life filled with the feeling of math. |
