Design And Application Of Photosynthesis Series Micro-courses In High School Biology Teaching

With the development of educational technology,information technology with multimedia technology and network technology as the core has penetrated into all aspects of social development.Accelerated development of science and technology,forming a social phenomenon of "knowledge explosion".More and more new teaching media and means are applied to the classroom,which will produce structural adjustments and changes in curriculum,teaching methods,teaching content and teacher knowledge structure,and inject new into the development of education and teaching.powerWith the emergence of teaching modes such as flipping classrooms and smart classrooms,micro-courses have gradually entered the classrooms of primary and secondary schools.At present,the development of high school biology micro curriculum is not mature enough.This research selects the hybrid teaching mode,which makes the micro-curricular as an auxiliary means to effectively combine with the classroom teaching,and conducts classroom practice to evaluate its teaching effect.First of all,through reading and collating relevant literature,summarizing the related concepts of micro-curriculum,the design pattern and characteristics of micro-curriculum,and the current status of high-level biological micro-curriculum teaching.Secondly,the author selected 221 students in the first year as the experimental subjects in the internship school,and used the questionnaire survey method and interview method to analyze the feasibility of the micro-curricular implementation in the high school biology classroom.The Practitioner's Edition of Biology is a compulsory part of the fifth chapter,"The Source of Energy-Light and Photosynthesis" as an example.This lesson is a difficult and difficult part of cell metabolism,and students will find it difficult to understand.As a new type of educational resource,micro-courses use video as the main carrier to show the micro-reaction in the process of photosynthesis through 3D animation,students can better understand the knowledge and deepen the impression.The software for micro-course production selection includes: Super Screen 9.0,Camtasia Studio 8,Focusy Animation Demonstration and Wancai Animation Master.Three micro-courses were produced using PPT recording and software synthesis: "Extraction and Separation of Pigments in Green Leaves","Exploration Process of Photosynthesis" and "Process of Photosynthesis".After the teaching content analysis,the analysis of the situation,the analysis of the software and the analysis of the application mode,the micro-courses produced were applied to the classroom for teaching experiments.Finally,a questionnaire survey was developed to analyze the teaching effect of the micro-course in the classroom.Through the statistical compilation of questionnaires,the results are obtained: 1.Micro-courses can improve students' interest in learning;2.Micro-curriculum can effectively develop students' self-learning ability;3.Micro-courses have achieved good results in classroom teaching.Teaching effect;4.Most students expressed their willingness to continue using the micro-course for study.After analyzing students' satisfaction with micro-courses and classroom performance,they conclude that teachers should make full use of existing teaching techniques in the teaching process to make the classroom more vivid and efficient,so that it is better Teaching services.The design of the micro-course should be tailored to the local conditions to create a more appropriate classroom for students.Infiltrate the core literacy teaching philosophy in biology teaching,cultivate students' ability of independent learning and scientific inquiry,and enhance rational thinking.The photosynthesis series micro-course designed and produced in this study can enrich the teaching resources to a certain extent,and provide a reference template for the development of biological micro-courses,which provides a new teaching idea for the realization of efficient classrooms.The hybrid teaching model combining online teaching and traditional teaching conforms to the development and needs of the times.It is of great significance to cultivate students' core literacy,improve their ability to learn independently,and meet the needs of individualized learning.
