The Construction And Practice Of The"Teaching-Learning-Evaluation Integration" Class Model Based On The Core Quality Of High School Chemistry

The high quality and efficiency of class is an important factor to guarantee the teaching quality.According to the chemistry curriculum standards formulated by the ministry of education in 2017,this paper advocates the teaching model of“teaching-learning-evaluation integration” with the purpose of developing students' core literacy in chemistry,that is,the teaching of teachers,the learning of students,and“evaluation” should be combined organically and applied systematically in every link of the classroom.On the basis of previous studies,combined with high school chemistry teaching present situation,the suggestions of experts and teachers and the needs of students,the author constructs the “teaching-learning-evaluation integration” class model based on the core quality oh high school chemistry,it is divided into teaching mode and student learning self-rating scale.Expecting to the implement the core literacy to explore a new chemical disciplines class model.By studying the requirements of the new curriculum standards,the evaluation system of the college entrance examination,and during the internship,the author observed the classroom situation of the backbone chemistry teachers in the high school,and analyzed the teaching links and teaching methods of the excellent chemistry teachers in developing the core quality of students' chemistry discipline in the class.Based on the research results of domestic and foreign scholars on “core accomplishment of chemistry”and “teaching-learning-evaluation integration”,and constantly modified and improved,the teaching-learning-evaluation integration classroom model of high school chemistry with “accomplishment text” was constructed,and the relationship between “teaching”,“learning” and “evaluation” was elaborated.On this basis,the author interviews teachersand students to analyze the cultivation methods and evaluation methods that teachers and students tend to adopt to evaluate the core quality of chemistry discipline.Preliminary constructed the evaluation index system,through the Delphi method to the modified structure at the beginning of scale,125 students selected to test for the first time scale,delete and modify the lower reliability index by SPSS.26,then select 125 students on the modified scale on the second test,using the method of factors analysis to detect the indicators,good reliability and validity of compiled based on high school chemistry discipline core literacy “teaching-learning-integration” of classroom learning form”.In the end,selecting four classes by the same teacher,250 students totally in empirical research,two classes as experimental classes,teaching by “integration of teaching-learning-evaluation” class model based on the core quality of high school chemistry.At the same time using the self-evaluation of students learning table test each link in the classroom of students learning effect;The other two classes conducted the traditional teaching mode as the control class.After more than three months of experimental research,it was found that the significant difference between the experimental class and the control class was more and more significant,which proved that the class model has certain practical significance.For example,the fourth chapter of this paper gives the experimental classes with the chapter of “chlorine and its compound”,to choice 250 students self-evaluation tables analysis found that: it has good reliability and validity of the self-assessment tables,among them,the experimental class students pay more attention to the core literacy,and that in comparative classes of students pay more attention to aspects of learning knowledge.Thus,the following conclusions are drawn:After the practice of the class mode of “teaching-learning-evaluation integration”based on the high school chemistry core quality,students have a clearer understanding of learning objectives and evaluation objectives,and can conduct a process evaluation on themselves in class,timely discover doubts in class,and conduct targeted learning,so as to improve learning efficiency in class.At the same time,through students' self-evaluation,teachers can timely master students' learning effect of each link in the classroom,they can adjust teaching strategies at any time,conduct targeted teaching,give students diversified evaluation methods,significantly improve teaching efficiency,ensure teaching quality in the class,and better develop students' core quality of chemistry.
