Research On Teaching Design Of Junior High School Biology Teaching Under TPACK Framework

Under the trend of educational informatization,teachers must constantly enhance their mastery of information technology and innovate effective teaching methods.The emergence of the TPACK framework has provided new ideas and approaches for teachers to effectively integrate information technology into subject teaching.However,how to integrate the TPACK framework with junior high school biology remains a problem that needs to be addressed.The purpose of this research is to explore how to enhance junior high school biology teaching using the TPACK framework.Through literature research,the study establishes a solid theoretical foundation by understanding the current research status both domestically and internationally.Based on the TPACK framework and following the principles of integration,student-centeredness,reflection,and adjustment,a model for designing junior high school biology teaching is constructed.The research adopts an experimental research method and selects two classes from School S as the research subjects,conducting a one-semester teaching practice based on the TPACK framework.Taking the topic "Adaptation and Influence of Organisms in the Environment" in Grade 7 as an example,a teaching case based on the TPACK framework is designed,and comprehensive evaluation is conducted through questionnaires,interviews,and observations from the perspectives of teacher evaluation,observer evaluation,and student evaluation.The overall implementation results show that the teaching design of junior high school biology based on the TPACK framework can effectively integrate the content of biology,technological knowledge,and teaching methods,improve teachers’ ability in information technology teaching,and provide certain guidance for teaching.However,the research also reveals issues such as insufficient teacher cognition and application of technology,as well as low student classroom participation.Finally,specific strategies and recommendations are proposed from the perspectives of students,teachers,and schools,including encouraging active student participation,establishing platforms for mutual assistance and communication,and improving TPACK evaluation.
