Research On Unit Teaching Design Based On Mathematical Operation Ability Cultivation

The "mathematics curriculum standard for general high school(2017 edition)" puts forward six core literacy of mathematics subject,points out the basic idea of mathematics study and the key ability of mathematics study,and Mathematics Operation Literacy is one of the six core literacy,in the whole process of learning mathematics.The solid mathematics operation ability,not only is studies the mathematics the premise,is also promotes the mathematics core literacy the foundation.However,there are many problems in students' learning,such as unclear calculation,poor calculation ability,irregular calculation steps and so on.On the one hand,the students' poor ability of operation is caused by the students' lack of exploration in the teaching process,on the other hand,it is caused by the students' weak foundation of operation and their inability to extract knowledge flexibly.Nowadays,the mathematics operation ability is playing more and more important role in the students' mathematics study.How to improve the students' operation ability is a problem that every educator should consider.As for how to improve students' computing ability,many scholars have studied and put forward different methods.Based on the research of the predecessors' reading analysis,found that the traditional teaching design can lead to fragmentation students learn knowledge,is not conducive to the students as a whole to grasp the knowledge,while unit teaching design from the Angle of the whole teaching material analysis,teaching design,has many advantages,and thus determine unit teaching design is the key point of this study.First of all,the first two chapters of the paper describe the research background and research ideas of the paper.By analyzing the research status of unit teaching design at home and abroad,the core concepts are defined and the research framework of the paper is formulated.Secondly,by issuing questionnaires to students to understand the current common computing problems of junior high school students,the collected questionnaires were analyzed and processed to judge the overall computing level of students,and it was found that the current junior high school students had problems in calculation,steps and other aspects,and the causes of the problems were analyzed.Thirdly,it explores the unit instructional design process to improve students' computing ability,analyzes the principles and design requirements of unit instructional design,and combines students' common computing problems,and puts forward a model of unit instructional design-"determine unit teaching theme,determine Unit learning objectives,design unit teaching plan,teaching design reflection and evaluation".Among them,the design unit teaching plan is divided into two parts: "the main line of unit teaching design" and "the main line of class teaching design" for design.In order to improve students' computing ability,the design of the calculation lesson type changes the previous teaching process of "introduction of situations,teaching new courses,and consolidation exercises".The author designed "introduction of situations-exploring calculations-clear calculations-standard steps-algorithm applications-The six links of "Summary and Improvement" allow students to improve their abilities in the exploration and application of mathematics.On the basis of the unit teaching design,the unit of"Rational Numbers and Operations" in the first volume of the seventh grade was selected to demonstrate the unit teaching design case.Then combined with the investigation and analysis of students' computing ability and the author's observation of students' common computing problems during the internship stage,the analysis discussed the strategies of unit teaching design to improve students' computing ability,such as establishing the problem in the real problem situation and strengthening the solution by the teacher.Strategies such as writing demonstration of the problem steps.Finally,unit teaching design is helpful to the overall mastery of knowledge and the development of students' abilities.The unit teaching steps combined with computing course design can help students improve their computing ability to a certain extent,and it is expected to provide some teaching reference for teachers working in the front line.
