A Practical Study On The Training Of High School Students' Mathematics Preview Ability Before Class

The curriculum reform emphasizes that teachers should not only teach students scientific and cultural knowledge,but also cultivate students' self-study ability,so that students can learn to study independently.Autonomous learning is an independent,planned learning activity,which fully reflects the main position of students.It is an important factor that affects the development of students.And the pre class preview of mathematics is an important way of autonomous learning.But now many high school students don't know how to do effective math preview.And most teachers do not pay much attention to the pre class preview.They think that students only need to listen in class or let students simply preview the textbook.They lack of scientific and effective preview guidance and supervision for students,and ultimately can not play the role of mathematics preview.In order to better cultivate the ability of mathematics pre class preview of senior high school students and improve the effectiveness of their independent learning,designing four kinds of before class preview plans and outline of preview questions for senior high school mathematics concept class,principle class,exercise class and review class,and carry out teaching experiments for experimental class and control class in two stages.That is to say,we should guide and supervise the experimental class' s mathematics preview before class,from the detailed guidance of the preview plan to the general guidance of the preview problem outline.We hope to explore the way of students' preview,improve students' ability of preview before math class,and realize the teaching of "to guide students,but never lead students' nose;to strictly require students,but never make students feel depressed;to inspire students to think at the beginning of the problem,and never give the final result to students",so as to prepare for the improvement of teaching quality.Through two research methods of questionnaire survey and teaching experiment,two parallel classes of Science in Cenxi No.2 Middle School were studied,the following conclusions are obtained:(1)According to the students' questionnaire survey and interview,the students have a good cognitive attitude towards the pre class mathematics preview.Most of the students are aware of the importance of the preview to the mathematics learning and think that the preview is conducive to improving the effectiveness of the mathematics learning.However,most of the students' pre class preview is not strong in execution and enthusiasm,which requires the guidance and supervision of teachers.According to the questionnaire survey of teachers,senior high school mathematics teachers all think that preview is helpful to students' mathematics learning and self-study ability,but there are few teachers who assign the task of mathematics preview,lacking the corresponding preview guidance and supervision.In addition,senior high school students' mathematics inverse quotient level is low,and their ability to deal with setbacks and difficulties in mathematics learning is not strong,so the difficulty design of preview materials should not be too large.(2)Senior high school students' overall pre-school mathematics ability is in the middle level.After the experiment of pre class mathematics preview,the ability of pre class mathematics preview in the experimental class has been improved,and the performance of the experimental class in the later period is significantly better than that of the control class.It shows that the preview and guidance activities explored by the author are conducive to students' learning mathematics and improving their math scores.(3)According to the survey data after the experiment,it is found that most students prefer to get detailed preview plans to guide the preview.On the whole,the preview plan is more in line with the needs of students in Cenxi No.2 Middle School.
