Theoretical And Practical Research On The Limited Teaching Of High School Chemistry Experiment

In chemical experiment teaching,the teacher need basis in 2017,put forward by the new curriculum standard,the correct understanding of the differences between students,follow the rules of the development of students,clear the chemical experiment teaching is limited by various factors and restriction,starting from the limited teaching ideas,in all kinds of limited teaching resources,to adjust teaching content accordingly and processing,selecting suitable for students to develop the teaching contents,adopt different strategies for teaching,in order to ensure the effective development of students,to avoid students"digest"or"do not have enough to eat"phenomenon.Through consulting a large number of literature,this study adopt the method of questionnaire and interview survey,survey the first-line teachers present situation of chemical experiment teaching factors that influence the chemical experiment teaching is selected according to students'different levels of development and adjust the teaching content of different depth.According to the survey of the status quo of three different depth teaching case,selected one of the cases in class passengers a secondary innovation and comparable study using SPSS 13.0 software to do correlation analysis,the result of the investigation,according to the conclusion to put forward the proposal of chemistry experiment teaching,and combined with the college entrance examination chemistry experiment to test chemical experiment teaching put forward the corresponding solutions.Research results show that the high school chemistry experiment limited teaching theory and practice of research for the proposed increases the application practice of the"limited teaching",further improve the"limited teaching"idea,based on the local culture,to the research of high school chemistry experiment provides a new Angle of view,lead teachers attach importance to the differences of students,the students of the selection of the zone of proximal development,optimization of teaching,teaching content in the limited teaching breakthrough is limited,to achieve the best teaching cffect.
