The Practice And Research Of The "topic" Teaching Activities In High School Biology

The latest New Curriculum Standard of High School Biology emphasis that the main target of the high school biology is increasing students,biological literacy.At the same time,the biological curriculum should pay attention to developing the students,ability of innovation,increasing the ability of independent study and encouraging students to communicate and cooperate.If exercise lessons are effective,students will deepen the understanding of knowledge and concept,they also establish a more perfect system of biological knowledge.During this process,students will gain more pleasure.In this background,we raise this "analyzing the question aloud"teaching pattern in biological exercise lesson in practice.Although,the study of "analyzing the question aloud"teaching pattern is relatively early,the study of this teaching pattern used in biological exercise lessons is fewer.There are some researches about experience about teaching,which are not systematic and profound.For this situation,I am trying to solve in this paper are these problems:first,the contents and principles of this teaching pattern.Second,its strategy.Third,exposing thought process.Fourth,its effect.The methods used in this paper include literature research method,questionnaire survey,interviewing method and experimental study.Through searching and reading literature,we summarize the concept and contents of this teaching pattern.Before the experiment,we took the questionnaire survey about the current situation of biological exercise lessons among five classes freshmen of high school in Nanjing.We found the situation are not great.We also consulted some biology teachers who gave precious suggestions.At last,we decided to choose two parallel classes to take the experiment in stages.According to the questionnaire survey before the experiment,it is found that the teaching method of the current high school biology problem sets is mainly taught by teachers.The students only listen to the lectures,and seldom let the students explain the problem sets,and the teaching effect is not ideal.Therefore,based on the findings of the survey and the suggestions of teacher interview,we summarized the principles of this teaching pattern,and introduced the contents of it in the chapter of "the photosynthetic action and respiration",which is to say the meaning,the conditions,the thought,the law and the reflection.After this activity,we took another questionnaire among the experimental class.We compare the mid-term contest grades with final exam grades.We also analyzed students' cores of exercise and performance of the activity.Compared with the traditional teaching way of exercise lesson,this activity can stimulate students'interest and participation enthusiasm,both the knowledge learning,concept and ability of literacy has significant improvement.There is a significant correlation between the score of exercise and the performance of this activity,and it has a good prediction effect on students' academic performance.Through the comparison between the mid-term and final examination results,it can be found that the activity has obvious effect on the improvement of students' academic performance...
