The Teaching Research Of "REDOX Reaction" Based On The Integration Of Teaching Evaluation

As an important branch of curriculum reform,the new curriculum standard clearly puts forward the curriculum evaluation concept of "the integration of teaching,learning and evaluation",and regards it as an important approach and basic strategy to cultivate students' chemistry discipline quality.How to apply the teaching mode of "teaching,learning and evaluation integration" to high school chemistry class,so as to effectively cultivate students' core literacy and promote students' concept understanding has become a new topic.Redox reaction is one of the core contents of high school chemistry,which runs through the whole high school chemistry learning,and is the key and difficult point of high school chemistry.Based on the knowledge content of REDOX reaction,exploring a new teaching mode based on the integration of teaching evaluation can provide reference value for promoting the breakthrough of high school chemistry classroom teaching.Were reviewed in this study about the integration of "teaching,learning,evaluation of" research and REDOX reaction,on the basis of teaching research,based on the integration of "teaching,learning,evaluation of" the essence of the connotation to construct the teaching goal as at the head of the three-dimensional teaching model,with specific,observable,evaluation of the teaching goal oriented to determine evaluation activity,situation and problems,teacher and student activities,service to achieve the goal of teaching.Based on the classroom teaching model,this paper designs the classroom teaching ideas based on the integration of "teaching,learning and evaluation" :(1)Making teaching objectives before class--the basis of the integration of teaching evaluation;(2)classroom teaching activities and developmental evaluation--the implementation of the integration of teaching evaluation;(3)understanding detection after class-teaching evaluation of the integration of the effect of feedback and,on the REDOX reaction was carried out based on the concept of "teaching,learning,evaluation of" integrated teaching design research,through the student interviews and questionnaire survey,the survey is based on the concept of integration of "teaching,learning and assessment" classroom teaching model and teaching method is feasible and effective,draws the following conclusions:(1)The realization of the integration of "teaching,learning and assessment" according to the curriculum standard,disciplines core literacy training goal,knowledge carrier to determine the teaching objective and student learning,teaching with the teaching goal of development to achieve the teaching goal and evaluate teachers' behavior,student activities,activities,and to measure the teaching goal to achieve the evaluation activity set in teaching process,according to the evaluation of teaching to reflect the performance of students,so as to promote the teaching goal(learning goals).Based on the essence of the integration of teaching,learning and evaluation,a classroom teaching model based on the integration of "teaching,learning and evaluation" is constructed.In the model,the leading role of teaching objectives is highlighted,and evaluation activities,situations and problems,teacher activities and student activities are determined based on specific,observable and measurable teaching objectives.(2)According to the purpose of the evaluation content through the classroom teaching design based on the integration of "teaching,learning and assessment" classroom teaching ideas,evaluation content can be divided into three parts: before the basis of integration of teaching target,teaching evaluation,classroom teaching activities and the developmental evaluation,the implementation of the teaching evaluation of integration approach,after-school detection level of understanding,the effect of the integration of teaching evaluation feedback.The integrated concept of "teaching,learning and evaluation" can be effectively implemented by combining the evaluation content with the teaching content through the chemical concept scale.(3)Judging from the reaction of student learning outcomes,based on the classroom teaching model and teaching ideas of classroom teaching to help students grasp chemistry knowledge to a certain extent,is advantageous to the student's understanding of concepts,reduce isomerization of want to produce,to develop the students chemistry discipline core literacy has a certain role in promoting.From the point of the results of interviews,will be in accordance with the classroom teaching model and teaching ideas to design the teaching design application in classroom teaching,through teachers' questions,comments,questions,the students' mutual and self-reported diversified evaluation methods,such as the teachers' teaching and students' learning and teaching evaluation,can effectively promote students' knowledge in the depth of understanding,thus developing students' chemistry discipline core literacy.To sum up,based on the concept of integration of "teaching,learning and assessment" classroom teaching model and teaching ideas can effectively implement the integration of "teaching,learning and assessment" concept,play evaluation function to promote the development of students' subject core accomplishment,promote the student to the depth of the concept of understanding,has certain feasibility and operability and productive.
