Teaching Design Of "Comprehensive And Practice" Based On 5E Teaching Model Elementary Mathematics

Regarding to the "Comprehensive and Practice" part of Primary School Mathematics,"Practice" means operation,thinking,communication,listening,"synthesis"is more than just the synthesis of mathematical knowledge,but also a synthesis of mathematics and life,and other disciplines.Since the teaching of the comprehensive and practice is not within the scope of the exam,it has been the long-term neglected state,With the in-depth advancement of the reform of my country’s new curriculum,although the status of the "Comprehensive and Practice" in primary school mathematics is improved,the teachers who were in the teaching first line are still lacking in teaching models for reference.By consulting the 5E teaching mode and the relevant documents of the "Comprehensive and Practice" course,the subject of the teaching design studies of "comprehensive and practical" mathematics course in second stages of primary school was confirmed based on the guidance of 5E teaching mode.I have selected a class of " How high is the big tree "in the main course type（practical inquiry type）for a complete teaching design,including the preliminary analysis of the lesson of "How high is the big tree",and the teaching goals,Teaching process and teaching evaluation three aspects of the lesson of "How high is the big tree ".After completing the entire teaching design,it is used in actual classroom teaching.In terms of the evaluation of the effect of classroom teaching,I determine whether the teaching goals of the design have been reached through the self-edited "Teaching Objectives".Based on the inquiry evaluation system prepared by Zhe min Zhu,Bing Jia and others,I designed the inquiry class observation table to judge the inquiry performance of students According to the results of the implementation,it can be found that the classroom under the guidance of the 5E teaching mode basically achieves the teaching goal,and the students’ exploration performance is better.Finally,four points of reflection and suggestions were carried out for the design and implementation of this teaching.
