Research On The Application Of "Learning Before Guiding--Problem Evaluation" Teaching Model In Senior High School Chemistry Teaching

With increasing comprehensive strength,the country put forward new requirements for talent training,especially for the young generation of independent learning ability,thinking innovation ability and comprehensive practice ability and so on various aspects put forward new requirements,and education as the core strength of national talent training,obligatory to the construction and development of talent training.Therefore,this study to develop students' independent cooperative inquiry learning ability as the goal,determine the "learning after guide-problem evaluation" teaching mode this research theme,and in Zhaotong city M middle school grade students as the object of practical research,through theory and practice research for high school learning chemistry to provide a new learning method,but also expected to provide a new perspective for chemistry teachers teaching.first,In this study,with the topic selection background and related research trends,The research purpose,content and method are clarified;Then expounds the relevant concept and theoretical basis of the teaching mode of "learning first then guide-problem evaluation",Provide theoretical guidance for this study;moreover,In order to understand the students 'current chemistry learning status and teachers' teaching status,Using the questionnaire survey and interview methods,Investigate and analyze the current situation of chemistry teaching in Zhaotong M Middle School,Find out the necessity and feasibility of implementing this study;on this basis,Based on the current research situation at home and abroad,Design problem solutions from three perspectives of class construction,team learning and evaluation system,It provides an improvement strategy for M Middle school to change the status quo;Then take the problem solution countermeasure as the main application line,The experimental method was used to study the two classes of Zhaotong M Middle School,After passing through a 4-month practice study,To test whether the teaching mode is effective for students to learn chemistry from both qualitative and quantitative perspectives;last,Combing and summarizing the research results of this study,Reflecreflect on the whole practice study,Research limitations and expectations are also proposed.Based on the above research process,(1)the theoretical research of "learning before guide-problem evaluation" provides reference for the change of teaching mode;(2)through the practical research,the students' cooperative learning ability,learning attitude,methods and habits;(3)through interviews,most students and teachers show that the model is effective.
