Unit Teaching Research On "Preliminary Acquaintance Of Fractions" Under The Core Literacy

It is a new direction for Chinese basic education curriculum reform to develop students’ core literacy.In addition,it’s the goal of basic education.However,the traditional teaching based on class period can not provide powerful support for the development of students’ core literacy.Meanwhile,the unit teaching based on core literacy can improve present situation and promote the development of students’ core literacy.The preliminary acquaintance of fraction is one of the most important units of mathematics in the period of compulsory education.It’s an important content that mathematics thinking can really come into the mind of pupils.It’s the basis for pupils to learn decimal,percentage,ratio and other knowledge;Therefore,the unit teaching of“preliminary acquaintance of fraction” based on core literacy can not only promote students’ understanding of fractions knowledge,but also cultivate students’ core literacy of mathematics.This research adopts four methods: literature research,questionnaire survey,text analysis and experimental research.Firstly,core literacy of primary school mathematics and the connotation of mathematics unit teaching are obtained from relevant literature,and the theoretical basis of supporting this research is sought.Second,it can be found that most of mathematics teachers are aware of infiltrating the core literacy of mathematics into the unit,after the survey about the status quo of primary school mathematics teachers’ teaching in " preliminary acquaintance of scores " by questionnaire.However,they are unable to implement the teaching aimed at developing the students’ mathematics core literacy,because they do not know the teaching strategy of developing the mathematics core literacy.Third,the research is analyzed theoretically.Unit teaching plan of “preliminary acquaintance of fractions " under the core literacy can be determined on the basis of analyzing the characteristics of mathematics unit teaching and the primary school mathematics core literacy,and the situation of " preliminary acquaintance of fractions” unit teaching,including analyzing unit teaching elements,analyzing unit core literacy,integrating unit teaching content,formulating unit teaching design and teaching implementation and analysis.Then,text analysis and experimental research were used to implement the scheme in the unit of "preliminary acquaintance of fractions".The experimental class carried out teaching in accordance with the overall planning of unit teaching design,while the control class carried out teaching in accordance with the previous teaching method.Finally,the implementation effect is analyzed from three aspects: classroom teaching comparison,after-class communication in experimental class and testing effect comparison.In the end,The results of this study are as follows: first,the unit teaching of "preliminary acquaintance of fractions " under the implementation of core literacy has a good effect,which can effectively cultivate students’ core literacy of mathematics in a relatively short time.Second students’ classroom participation and learning interest have been improved.Experimental class students can mathematize the living situation,and their ability of finding,proposing,analyzing and solving problems has been improved.Compared with the traditional teaching,the unit teaching of primary mathematics under the core literacy has advantages in teaching content,teaching objectives and teaching process design.
