The Development And Application Of Digital Teaching Resources Based On The Concept Of Life

It has become the main goal of biology teaching in senior high school to cultivate students' concept of life and core competence of biology.In the new era,the development of digital education is imperative,and the digital construction of teaching resources is also mentioned in various policy documents and needs to be paid attention to,which shows that digital teaching resources play an important role in education and teaching.The main content of this paper is to develop digital teaching resources for the concept of life to assist teaching and help students establish the concept of life.By using the literature research,this paper comprehensively analyzes the development status of digital teaching resources about the concept of life at home and abroad,and then summarizes the concept,characteristics,teaching mode,theoretical basis and resource development process of life concept and digital teaching resources.After that,a questionnaire survey was conducted among the teachers and students of the No.1 Middle School in Jiaxiang County,Jining City,Shandong Province,to summarize and analyze the teachers' basic understanding and development and application of digital teaching resources on life concepts,as well as students' situation of using them to cultivate life concepts.The results show that it is more beneficial for biology teachers to use digital teaching resources in classroom teaching to construct the core concepts,important concepts and secondary concepts of biology.However,due to teachers' shallow understanding of digital teaching resources,weak ability to develop digital teaching resources in this field and passive attitude,teachers are aware of the urgency of cultivating students' concept of life and the importance of digital teaching resources in classroom teaching,but the actual teaching effect in cultivating students' concept of life is not satisfactory.In this paper,taking the third chapter "The Nature of Genes" of the latest edition of Biology Compulsory 2 of PEP as an example,the digital teaching resources about the concept of life are developed and the teaching practice is carried out in order to solve the existing problems.According to the curriculum standards and teaching objectives,various types of digital teaching resources at home and abroad were widely collected through the Internet;According to the content of teaching and the actual situation of students,the collected resources were recreated by using Photoshop,ijianji and other image and video processing software,and the mind map is constructed by using Xmind to develop suitable digital teaching resources;According to the teaching mode of related digital teaching resources,this chapter is designed and applied to teaching.Four parallel classes in the first grade of Jiaxiang No.1 Middle School were selected as the research objects for teaching practice.A summary and analysis of the results of the pre-test and post-test papers shows that the application of digital teaching resources can can help teachers explain knowledge deeply and clearly and make students study by interacting with multiple senses from perceptual knowledge to rational knowledge,and can effectively promote the concept of biology to the concept of life.The effect of cultivating students' concept of life is better than that of conventional teaching.Therefore,the following suggestions are put forward: First,we must conduct hierarchical and diversified training for teachers,improving teachers' ability to collect and screen digital resources and integrate information technology and biology;second,establish and improve the digital teaching resource development system to provide various supports for the development and application of digital teaching resources for life concepts.
