Design,Development And Application Of Micro-courses For Basic Courses In Secondary Vocational Schools

With the rapid development of Internet technology and multimedia technology,the popularity of smart mobile devices such as tablet PCs and mobile phones,microblogs,micro-business,WeChat,micro-speaking,micro-movie,micro-video and other "micro" things are quickly accepted by users,people You can get the information and knowledge you are interested in from the smart terminal anytime and anywhere,forming a unique "micro" culture.Educational resources are also characterized by individuality,diversity,and miniaturization to meet the needs of personalized learning.The traditional classroom teaching mode can not fully meet the learning needs of modern secondary vocational students.The micro-course is a new digital learning resource based on micro-video learning within 10 minutes,supplemented by elements such as micro-course learning task list.It is uniquely short.The advantages of small,fine and sturdy have been widely used in new types of flipping topics,mixed teaching and online open courses,which have received more and more attention from the education community.The traditional classroom teaching mode is expected to make breakthroughs and improvements in terms of learning methods,learning concepts and learning effects.At present,the state continues to promote the informationization reform of secondary vocational education,which brings opportunities for the development and reform of education and teaching in secondary vocational schools.As a product of the combination of contemporary education and network development,micro-courses are in full swing in basic education and higher education.However,in secondary vocational education,they are slightly thin.The role of micro-courses in promoting the reform of secondary vocational education is not Play it out.The application of micro-courses in the teaching of professional basic courses in secondary vocational schools is of great significance for promoting the implementation of digital learning,personalized learning and digital resources construction and application in secondary vocational schools.This research adopts the idea of “propose problem-problem analysis-propose strategy-developing application case-implementation result analysis”,which mainly includes the following contents: First,study relevant literature and materials,and sort out the current situation of micro-classes at home and abroad.,put forward research questions,research ideas and research methods.Second,define the core concepts of research and study the theoretical basis of the application of micro-teaching.Thirdly,it analyzes the current situation of basic course teaching of chemical engineering specialty in secondary vocational school,studies the type and application mode of micro-curricular application,and analyzes the feasibility of applying micro-course in the teaching of basic courses in secondary vocational schools.Fourthly,through the research and practice summary,the problem-oriented micro-class types applicable to the basic course of chemical engineering specialty,and the micro-course design principles,development models and processes are proposed.Fifthly,taking the practice of the micro-courses of "Sodium Properties" and "General Solution Configuration" in the Basic Chemistry Course of the Secondary Vocational School as an example,the practical research on the design and application of the micro-course is carried out,and the practical research of the case is summarized.Five strategies for the practice of micro-courses in the basic course of chemical engineering,analyze the implementation effect of the application of microcourses,and summarize the research results.According to the research,under the guidance of the student-centered instructional design concept,the online and offline flipping classroom teaching mode is adopted,and the students use the micro-courses to conduct online self-learning,complete the learning task list,participate in the discussion and discuss each other.Answering questions and doubts,students take the initiative and actively,and effectively improve the quality of learning.This teaching mode has a good effect on the learning effect of the professional basic course knowledge of the students majoring in chemical engineering and the vocational ability training of the students.It has a good effect on improving students' cognitive level,mobilizing students to actively learn and improve their interest in learning.enhancement.In the study,different student individuals were found to have a special attention to the specific micro-curriculum performance types.For this reason,the research on the micro-course performance types is worthy of further discussion in the future.
