Probability Unit Teaching Research Based On The Core Literacy Of Mathematics

The core literacy of mathematics is a necessary character and key ability for students to learn mathematics.According to the requirements of the 2017 version of the general high school mathematics curriculum standards,the core literacy of developing students in the subject-unit teaching is a new round of high school mathematics courses.Requirements and mission of reform goals.The unit teaching mode can help students grasp the knowledge system as a whole,and build a clear knowledge context in their minds,which is conducive to the development of core literacy in mathematics.Based on the literature research,taking the topic of elective probability as an example,and the“probability”knowledge group as the knowledge carrier of research,the whole unit teaching design is carried out with ADDIE model and system theory as guidance,and put into teaching practice.The main research contents are as follows: Study the specific requirements of the “probability” unit in the “Course Standards”,grasp the overall knowledge system of the “probability”part,and analyze the teaching elements of the probability unit;The discrete random variables and their“Distribution column”is an example of unit design,and it is compared with class teaching.Two classes with equivalent learning levels are selected as research objects through pre-tests,and teaching practice is carried out to study and test the effectiveness of unit teaching.Studies have shown that: unit teaching based on core literacy can make teaching design more scientific,make teachers 'teaching methods more comprehensive and systematic,and can more effectively cultivate students' core literacy in the same time;and In the course of teaching practice,it was found that unit teaching can effectively improve the phenomenon of grade polarization in a class to a certain extent.Therefore,we should pay attention to the research and formulation of unit teaching objectives in teaching.The teaching objectives should highlight the core literacy of mathematics disciplines,and effectively use unit teaching to promote the development of core literacy of students' mathematics disciplines.
