Research On The Application Of ADI Instruction Model In High School Biology SSI Teaching

Argument Driven Inquiry(ADI)instruction model based on the constructivism learning theory and cognitivism learning theory,aims to promote the demonstration activities,promotes argument in the application of social and scientific knowledge construction.It can encourage students to collect data and form argument,help students to understand the nature of science,to develop demonstration ability,to cultivate scientific thinking through similar scientists' demonstration process.Socioscientific Issues(SSI)teaching is based on situational learning theory and dialogue teaching theory.It provides students with scientific,social and controversial situation,to carry out scientific argument,discuss controversial issues,help students apply scientific knowledge,understand the nature of science,form the correct scientific view,cultivate the ability to participate in social decision-making.At present,ADI instruction model and SSI teaching have respectively introduced into high school biology teaching,but no ADI instruction model has been found to carry out SSI teaching.The core of ADI instruction model is to promote the progress of demonstration activities.SSI is demonstrable teaching content,so ADI and SSI have the basis of integration.On the basis of consulting a large number of literature related to ADI instruction model and SSI teaching,this study excavates the high school biology textbooks,summarizes the SSI content and the corresponding chapter positions,and discusses the principles and strategies of teaching.The SSI in high school biology is distributed in each module.According to the strength of the conflict,it can be divided into two types: strong conflict issues and weak conflict issues.Using ADI instruction model to carry out SSI teaching should adjust the design of the teaching steps according to the strength of topic conflict.This study takes the two topics of “Evaluating the application of hormone drugs”and “How to treat AIDS patients fairly” to present the teaching design of strong conflict issues and weak conflict issues respectively.The “demonstration meeting” stage is the main part of ADI instruction model.When the issue conflict is strong,the stage adopts debate form,and students take different positions to discuss solutions satisfactory to all parties.When the issue conflict is weak,this stage adopts discussion form and students propose their own opinions and explain the solution.In order to test the feasibility of ADI instruction model in biology SSI teaching,two classes were selected in parallel classes of a high school in Xinyang,and there was no significant difference in students' participation level and biology grades between the two classes.The control class adopts traditional SSI teaching,and the experimental class uses ADI instruction model to carry out SSI teaching for a semester.The level of students' participation in both classes and the written demonstration level of the experimental class were measured and analyzed.The results showed that the students' participation in the control class did not increase significantly,the students' participation in the experimental class increased significantly,and the written demonstration level of the experimental class was also increased significantly.It is found that when the ADI instruction model is applied in the SSI teaching of biology in high school,the “demonstration meeting” stage corresponding to strong conflict issues and weak conflict issues should be held respectively in the form of debate and discussion.The application can improve students' participation in class and the level of written demonstration.It has high educational value and research value.
