| Science and education can revitalize the country,and education has always been the top priority the country.The layered teaching method is a targeted teaching that complies with the students’ personality development.The group cooperation learning model encourages collaboration in group and competition between groups under the guidance of teachers.It’s hard to guide students in accordance with their aptitude and treat them as main part because of the large class capacity.The layered teaching method and group cooperation learning model are combined and applied to the practice of mathematics teaching in high school.It is hoped to improve students’ interest in mathematics learning,cooperation inquiry ability and the core literacy of mathematics.This study firstly adopts the literature research method to sort out the relevant literature and theories.On this basis,it combines the actual questionnaire and uses the questionnaire method to conduct multi-dimensional surveys of teachers and students.Secondly,it formulates a strategy based on the analysis results of the questionnaire survey combined with theory and one year of practical experience to formulate a layered teaching model based on group cooperation.Through the collection of 65 teacher questionnaires online,1,864 student questionnaires were collected offline at a demonstration high school in Henan Province(remembered as M High School).The analysis of the results of the teacher’s questionnaire survey found that:(1)More than 70% of high school mathematics teachers understand and use layered and group cooperation teaching,but they have a shallow degree of implementation;(2)Teachers face many difficulties in stratified teaching,such as lack of insights and inability to take into account the whole;(3)Teachers face many difficulties in stratified teaching,such as lack of insight and inability to take into account the whole.The analysis of the survey results of the student questionnaire found that:(1)Students like mathematics,but feel that learning is slightly difficult,they alos like and recognise stratification and group cooperation learning;(2)There are many difficulties in learning,such as difficult classroom learning,low homework completion rate,low participation in group activities,and low learning efficiency.According to the statistical analysis of the questionnaire results,combined with relevant theories,the opinions of excellent front-line teachers and teaching practice experience,the construction strategy of a layered teaching model based on group cooperation is formulated.Under the guidance of the strategy,the two-month experiment was carried out with two sophomore science classes in M High School as experimental groups and control groups.Before the experiment,a year of exploration is conducted to formulate a suitable daily performance points system for high school students.The daily performance of students was tracked for two months by using the points system.The students’ literacy was evaluated according to Yu Ping’s mathematical core literacy division.There are to prepare for the later formal experiment.During the experiment,the points system was used to track the daily performance.At the same time,the student stratification and teaching stratification based on group cooperation were designed according to the students’ daily performance scores and literacy level.The three teaching designs were introduced in detail.Layered teaching objectives are formulated before class.Layered teaching contents are carried out and group cooperative inquiry learning is interspersed.During the period layered evaluation is given in time.Layered homework is assigned after class.After the experiment,the student assessment is evaluated again.We summarize the results and deficiencies of this practice by combining the comparative analysis of the literacy and daily performance points before and after the experiment.From the perspective of pre-test and post-test of studentliteracy,there is no significant difference in the two classes in the previous test.The posttest of the experimental class was 83.3906,and that of the control class was 78.3077.The posttest of the experimental literacy of the experimental class has benn significantly improved.Judging from the daily performance points before and after,little difference clould be found between the two classes in the pretest.But the experimental class is 19.2500 and the controlclass is15.0154 in the posttest.The daily learning status and attitude of the students in the experimental class are obviously better.The comparative analysis of literacy and daily performance points before and after the experiment shows that the stratified teaching method based on group cooperation is meaningful in high school mathematics teaching.This model has effectively improved students’ mathematical literacy and learning ability. |
