Based On The Chemistry Core Quality Of The "Five-Line In One" Teaching Model Establishment And Case Study

The new high school chemistry curriculum standard further clarifies the requirements and orientation of general high school education,emphasizes the further improvement of students' comprehensive quality,focuses on the development of core literacy,and cultivates students' scientific and cultural literacy and independent development ability.At present,the problems existing in the chemistry classroom in the first line high school are the lack of diversity of teaching mode,the level of curriculum is too low,and the urgent need for a new teaching mode to update the teaching method for the construction and optimization of the chemistry efficient classroom in middle school.In order to explore the mastery of core literacy,the students and teachers were investigated and interviewed separately,and the difficult problems of core literacy development at the present stage were analyzed and the teaching mode of "Five-line in one" was established.The model aims to transform chemical problems into learning tasks based on situation,acquire knowledge by solving problems,establish a thinking framework for solving chemical problems,and describe the learning process through testing and evaluation.Cultivate students to form scientific inquiry thinking and rigorous scientific attitude.In this study,"Properties of Nitric Acid "," Writing of Electrode Equation" and " Properties of Ethanol " were selected for teaching cases design.In this study,a literature analysis,questionnaire,interviews,statistics,case studies law five kinds of research methods,choose a high school sophomore(5)and sophomore classes(6)class two class 103 The students were the subjects of practice,conducted a questionnaire survey of 103 students and carried out the teaching practice of the "five-line in one" teaching mode in the experimental class.According to the pre-test of the students in the experimental class and the control class,the SPSS 24.0software is used to analyze the results.The statistical analysis results show that the academic achievement and cognition of the two classes are close,which can be used as the object of comparison experiment.In the experimental class,the teaching mode of "five-line in one" is adopted,After the course,the students of the experimental class and the control class were tested,the results of the two classes before and after teaching practice were analyzed by SPSS 24.0 software,and the students of the experimental class were interviewed.The experimental results show that the average chemical scores of the students in the experimental class with the "five-line in one" teaching mode are significantly higher than those in the control class,and there are significant differences between the experimental class and the control class.
