Research On Problem Chain Of Autonomous Pre-learning In Junior Middle School

It is a learning society in today's information society.With the rapid development of science and technology,the rapid growth of information and knowledge,the shortening of the cycle of knowledge renewal,the frequency of innovation,and the high request of people's quality,the corresponding national learning and lifelong learning become the driving force of the country to maintain competition and the vitality of innovation.Learning has become a lifelong task for us,and the most important thing is to learn autonomous pre-learning.The learning style required by the new curriculum reform emphasizes the importance of autonomous pre-learning.However,the current middle school students have a very weak awareness of pre-learning in mathematics,and they have not developed good pre-learning habits.And there is not enough scientific and effective pre-learning method.The new curriculum standards also advocate a proactive and courageous approach to learning,so we are designing a “Problem Chain of Autonomous Pre-learning” model to guide students through effective pre-class preparation.literature analysis method,investigation and research method,and case analysis method are used in the paper.Firstly,through literature analysis,this paper makes survey and questionnaires from students and teachers to investigate the current situation of the mathematics pre-learning.In the suvery,konwing the pre-learning methods of teachers and students,carrying out futher theoretical exploration in combination with the academic situation,the paper defines the relevant concepts and theoretical fondations of “Problem Chain of Autonomous Pre-learning”.Based on literature research and questionnaire survey,six principles of question chain design are put forward: goal-oriented principle,appropriateness principle,enlightenment principle,step-by-step principle,open exploration principle and short and precise principle.At the same time,four strategies of problem chain design are obtained:(1)experimental observation inductive design,(2)associative analogy design,(3)variant design,(4)regression design.All of these help to guide the case study of Problem Chain of Autonomous Pre-learning.By using two preview modes in two parallel classes,it is found that Problem Chain of Autonomous Pre-learning has a significant impact on improving students' math performance,and " Problem Chain of Autonomous Pre-learning can improve students' learning interest,learning initiative and inquiry ability to a certain extent.Based on the research,the study of junior high school mathematics needs the support of the preparatory activities.The development of students' autonomous pre-learning habits not only requires the initiative of the students,but also requires the teachers to use the teaching wisdom to carefully arrange and guide the pre-study content,creating more chances for the students' lifelong learning.Due to the rush of time,the design process of testing and perfecting the problem chain needs time to be further verified.Therefore,the design and implementation of the “problem chain autonomous pre-learning” requires more educators to continue exploring.
