Research On The Optimization Of Biology Experiment Teaching In Junior Middle School Based On The Concept Of Teaching Into Daily Life

Biology is a natural science course.The new curriculum standard and the latest core literacy require students to have scientific inquiry ability,rigorous logical thinking,flexible knowledge construction ability and problem solving ability,accurate analysis and induction ability and expression of biological professional terms Ability etc.Experiments are the basis of biology and are the basis for many biological theories.Biology experiment teaching can cultivate students’ innovation ability,operation ability,and practical ability.If the experiment effect is not good,it will interfere with the teaching effect.The curriculum standard puts forward the curriculum concept of "focus on connection with life".This concept coincides with the concept of teaching life.The author uses the concept of "teaching life" to improve junior high school biology experiment teaching to get better Classroom effect.First of all,through the literature research to understand the situation of experimental teaching of biology at home and abroad,it is found that the mode of experimental teaching in foreign countries is very mature,and not only put forward many innovative theories,but also have put them into practice in education and teaching,while in China it is more at the level of theory.Secondly,taking the People’s Education version of junior high school biology as the research object,through a questionnaire survey of some junior high schools in Qingdao,we understand the development of junior high school biology experiments.From the perspective of the establishment,some experiments are not effective and difficult to operate.The low opening rate for reasons such as too large indicates that there is a lot of room for optimization of junior middle school biology experiment teaching.Combining the findings in actual teaching,investigating and interviewing first-line junior middle school biology teachers to find out why some experiments are difficult to carry out,so as to determine Principles of optimizing junior high school biology experiments.Based on the concept of teaching life,the optimization was carried out in teaching practice from the aspects of experimental objects,experimental protocols and teaching procedures,and the changes in students’ attitudes towards learning biology and classroom atmosphere were analyzed before and after the optimization through case analysis,questionnaire survey and classroom observation.The research sequence of this paper is:identification of problems,formulation of questions,formulation of optimization principles,conduct optimized classroom teaching,analyze data results,scientifically compare changes before and after optimization,and summarize optimization strategies.This study also shows that after the optimization of experimental courses based on the ideas of adapting measures to local conditions,environmental protection,and student-oriented experiments,students are more active in terms of interest in biological learning,degree of love,and attitude towards experimental optimization.Through classroom observations,it was also found that the optimized experimental operation process,student participation status,classroom atmosphere and teaching goals achieved good changes.
