| Mathematics concept is the core of mathematics,an important cornerstone for learning all kinds of mathematical theorems and propositions,and the key for students to form mathematical thoughts.Mathematics is a thinking form that reflects the essential attribute of the relationship between spatial form and quantity in the real world.However,due to the high abstraction of mathematical concepts and students’ lack of active construction ability,their understanding of concepts mostly stays at the level of applying problems,and they fail to really understand the essence of mathematical concepts,which hinders students’ development.Because of the backward regional economic conditions in rural senior high schools,it takes a short time to popularize the interactive intelligent tablet.Many front-line teachers can’t give full play to the advantages of the interactive intelligent tablet in the teaching process because of the lack of professional training,outdated educational concepts,insufficient motivation for curriculum reform and other factors.The teaching mode still stays in the simple combination of "blackboard+chalk+multimedia",and the communication between teachers and students still stays in the traditional teaching mode,which is single and inefficient.Therefore,this paper aims at cultivating and developing students’ core qualities such as mathematical abstraction and mathematical modeling.According to the teaching characteristics of mathematical concepts and the cognitive development law of senior high school students,relying on interactive intelligent tablet,this paper tries to explore the teaching strategies of senior high school mathematical concepts based on interactive intelligent tablet,so as to improve the teaching situation and the effect of concept teaching.Firstly,this paper adopts various research methods,such as literature research,investigation research and experimental research,analyzes the research status of interactive intelligent flat-panel teaching at home and abroad and the research status of mathematics concept teaching strategies in senior high schools.Combined with the current situation and existing problems of mathematics teaching in rural senior high schools,it is found that students can’t grasp the essence of mathematics concepts,and don’t understand the connotation and extension of concepts,which are the main reasons for subsequent learning difficulties.Then,based on constructivist learning theory,meaningful receptive learning theory,Friedenthal’s re-creation theory,information technology and curriculum integration theory,and taking two models of high school mathematics concept acquisition,namely concept formation model and concept assimilation model,as basic models,the concept teaching strategy based on interactive intelligent tablet is discussed.Finally,taking the Concept of Function and Exponential Function and Its Properties as examples,the teaching design is discussed,the teaching implementation is carried out based on the teaching design,and the teaching experiment lasts for two months.Based on the data of the pre-and post-test scores of the experimental class and the control class,SPSS22.0 is used for analysis,and it is verified that the students in the experimental class have a better understanding of concepts than those in the control class.After the experiment,summarize the teaching process,reflect on the teaching process,put forward the optimization scheme and improve the teaching strategy.The results show that:First,in the teaching of mathematical concepts in rural senior high schools,there are problems in students’ learning and teachers’ teaching.As far as students are concerned,it is a common phenomenon that rural senior high school students have weak mathematical foundation and no good study habits,which leads to poor mathematical learning effect when they can’t understand the concepts by rote.For teachers,poor presentation of teaching links and imprecise and standardized drawing in concept teaching have also caused poor teaching results.Secondly,creative application of interactive intelligent tablet can better promote the formation and assimilation of mathematical concepts.The strategies of using interactive intelligent tablet to promote the formation of mathematical concepts are as follows: 1.Creating scenarios,diversified representations and providing positive examples of concepts;2.Ask questions to guide and analyze the common essential attributes of examples;3.To solve problems,teachers and students sum up essential attributes together,and "curtain" focuses on key points;4.Understand the concept,excavate the connotation and extension of the concept,and break through the important and difficult points of "micro-course";5.Consolidate understanding,and "screen","annotation" and "evaluation" promote students’ reflection and migration;6."Mind mapping" builds a platform to form a conceptual domain(department).The strategies of applying interactive intelligent tablet to promote assimilation of mathematical concepts are as follows: 1.Creating scenarios,diversified representations,and presenting the first organizers;2.Define the concept,"curtain" focuses on key points;3.Identification,analysis and assimilation of concepts,and "classroom activities" deepen the understanding of concepts;4.Strengthen the concept,"function","mathematical sketchpad" and "geometry" to solve drawing problems,which is intuitive and standard;5.Apply concepts to solve typical examples,and "screen","annotation" and "evaluation" promote students’ reflection and transfer;6."Mind mapping" builds a platform to form a conceptual domain(department). |
