| Under the background of education informatization,mathematics key competencies were put forward by the mathematics curriculum standard of general high school(2017 edition),which were placed on the important position of students' ability cultivation.At present,both key competencies and informatization teaching are hot issues in the field of education research,but there are few research achievements on how to better cultivate students' key competencies in informatization teaching.Taking solid geometry as an example,we study the related problems on high school mathematics informatization teaching under the guidance of key competencies by using the methods of literature analysis,questionnaire survey and interview etc.The main work and research results are as follows.1 We have done a questionnaire survey on students in a high school of Ningcheng,Chifeng City,Inner Mongolia,and then made an interview with the mathematics teachers in this school.Through the analysis of questionnaire survey data and the interview results,we find that there are some problems in the current high school mathematics informatization teaching such as not clear objects in the cultivation of key competencies,lack of importance and monotonous training method.2 We study how to add the advanced scientific and technological achievements into the high school mathematics informatization teaching.In order to better cultivate key competencies for students,we present the informatization teaching mode that can be applied to both the contemporary and future,such as "Internet + education" mode and "AI + data + education" mode.3 We put forward the reference strategy for high school mathematics informatization teaching under the guidance of key competencies by combining the problems existing in high school mathematics informatization teaching under the guidance of key competencies and the case analysis,i.e.,achieving "four guarantees",realizing "three musts",and following the "three aspects". |
