Application Practice Of Compound Teaching Mode Based On Chemical Core Quality

In recent years,the "core literacy" has become a hot topic in the educational attention,discipline core literacy also arises at the historic moment,in order to make the students at the core of quality get better development,the education are to explore suitable teaching mode,this study by the reference literature is proposed based on online and offline learning the teaching mode of combining elements of compound part is the important content of high school chemistry,sort is more,in view of the elements and compounds content’s mad,students just passively accept knowledge learning situation often causes memory difficulties,so students can independently constructed a system of knowledge related to personal accomplishment,knowledge are especially important,this study developed based on the chemical under the core accomplishment of “five links before class,class three steps”teaching mode,through before class under the guidance of teachers using information technology to make chemical core literacy tiny fragments and courseware,the micro study case teaching resources,such as students autonomous learning anytime and anywhere before the class,class of complicated problems students absorb knowledge。This study section 2 o ’clock required a chapter 4 as the research content,selection of the element concentration in seawater-chlorine lesson example is studied,and the curriculum resources development design and specific implementation process,evaluate the practice results,including:⑴students’ in-class test scores,students feel this lesson interviews:In the course design and implementation process,the teachers should reflect and experience;⑵In this paper,we discuss the mixed teaching mode with the experts and key teachers;⑶This study provides a reference for the teaching design cases and the implementation of the mixed teaching mode in the middle school chemistry class,and also makes relevant exploration on the feasibility analysis。This lesson is divided into four parts:⑴preparation stage:at this stage a lot of mixed teaching related literature and chlorine,familiar with mixed teaching practice,teaching mode and predecessors of chlorine gas and first-line teachers teaching difficult point,semi-structured interviews to understand chlorine gas was designed and developed based on the chemical package under the guidance of learning resources,core literacy class statistics student learning problems in case discussion,targeted classroom teaching design;⑵implementation stage:the experiment class students in the use of learning resource package for self-study before class,and complete the corresponding micro study case,through the We Chat platform collection problem summary,report in class communication,problem solving;The researcher and the teacher,in two different modes of classroom teaching contrast reflection;⑶assessment and analysis stage: at the end of the session,that in comparative classes to learn,you can give classroom tests knowledge,reference the student learn the task achievement,interview students class expert views on mixed teaching mode implemented attitude;...
