Research On Practical Teaching Design Of High School Biology Based On ADDIE Model ——Take Molecules And Cells 1,a Compulsory Course Of High School Biology As An Example

The 2017 edition of Biology Curriculum Standards for Ordinary High Schools proposes that “teaching process emphasizes practice”.Teaching characterized by practice will not only directly affect the implementation of scientific inquiry and scientific thinking in the core qualities,but also indirectly affect the achievement of the other two core qualities.Classroom is the main place for practical teaching of high school biology.How to carry out practical teaching and point to the core accomplishment is an important task for every biology teacher to think and practice.By analyzing the correlation of ADDIE mode（ADDIE teaching design system mode）and classroom practice teaching,the necessity of guiding classroom practice teaching by ADDIE mode is clarified,and then try to implement classroom practice teaching design based on ADDIE mode in high school biology teaching,so as to cultivate students’ scientific inquiry ability.In this study,the cultivation of students’ scientific inquiry ability based on ADDIE mode was explored through literature research method,questionnaire survey method and educational experiment method.First,through the student questionnaire,to understand the status quo of classroom practice teaching.Secondly,discuss the necessity of ADDIE mode to guide classroom practice teaching design from the theoretical level,clarify the principle of ADDIE mode to guide classroom practice teaching,and construct the teaching design framework.In the framework,different teaching design modes are developed for the contents of classroom practice teaching,including scientific inquiry and engineering tasks,respectively,and case development is developed based on the teaching mode.Thirdly,the developed teaching cases will be applied to the classroom to implement the teaching practice.Finally,compare the changes of the experimental group and the control group before and after the implementation of classroom practice teaching,so as to judge the effectiveness of the classroom practice teaching design based on the ADDIE model.SPSS software is used to analyze the practice research data.The results show that:First,the construction of high school biology classroom practice teaching design framework based on ADDIE model is feasible.Second,the teaching design based on ADDIE model can significantly improve students’ scientific inquiry ability in six aspects: “inquiry”,“design explore”,“explore”,“analysis and clarify the experimental results”,“evaluation and demonstration”,“communication and cooperation” has been promoted,“to explore" design” and “analysis and clarify the experimental results”,and then improve students’ scientific inquiry ability.At the same time,it can also improve students’ ability to solve problems.It proves that the teaching design of classroom practice based on ADDIE model is reasonable and effective.Third,we developed cases of classroom practice teaching based on the ADDIE model.The developed cases of classroom practice teaching based on ADDIE model,applied in teaching practice,are effective for improving students’ scientific inquiry ability.Therefore,therefore,these cases can provide reference for front-line biology teachers to carry out classroom practice teaching.
