Research On Junior Middle School Science Smart Class Teaching Based On Tablet Computer

Education is moving into an era of "Internet + education".The deep integration of the Internet and education has become the trend of educational development.Smart class can realize the full-time communication of teachers,parents,and administrators,and effectively integrate on-campus and off-campus teaching scenarios.Therefore,studying smart education in primary and middle schools has positive practical significance.At the same time,the tablets,as a smart terminal with convenient and strong interaction,are introduced into the smart class,which helps to make full use of the smart class' s advantages.This thesis is to investigate the current status of the tablet use in teaching in science classrooms in H City.The questionnaire is designed from four dimensions including basic information,classroom learning process,classroom learning effect,and learning interest.Key public schools,ordinary public schools,key private schools and ordinary private schools in H city are selected to collect data,and we find that smart devices such as tablets have become a normal teaching tools of science classrooms,and they help to improve course learning resources,students' thinking ability and learning interest to some extent,but there are still teachers who only display courseware and use tablets only in public classes,and problems such as the lack of interactivity,which means we have not really realized the intelligence of science classrooms.Therefore,the author believes that it is imperative to establish the smart class based on tablet computers.Combining the relevant literature of tablets and smart class,the author designs the teaching process of tablet smart class.Based on this,three optimal teaching plans about smart class of science in junior high school are designed,including "Composition of Water","Models and Symbols of Particles" and "Sprout of Seeds"."Composition of Water" is selected to teach in experimental classes and control classes for tablet smart class teaching and general teaching respectively.The research results show that the experimental classes perform better in terms of learning enthusiasm,participation,and homework completion.In the teaching practice,four strategies of smart class teaching based on tablets are summarized: smart push strategy,three-dimensional interactive strategy,timely feedback strategy,and quantitative teaching strategy.The study concludes that compared with the traditional science classroom,the scientific smart class based on tablets has four following advantages.The first is data-based teaching decision-making.The teaching process has changed from relying on teachers' teaching experience in the past to relying on objective data in teaching,in order to accurately learn the learning situation,and make decisions for teachers.The second is instant evaluation feedback.In the smart class teaching,dynamic learning evaluation is adopted,so that instant and dynamic diagnosis and evaluation of information feedback are achieved.Thus a formative teaching evaluation system is reconstructed.The third is three-dimensional communication and interaction.The communication and interaction of smart class teaching is more vivid and flexible,and the communications between teachers and students,or between students are diversified.The fourth is smart push of resource.Smart class provides learners with a variety of rich media resources,and can intelligently push targeted learning materials based on the individual characteristics and differences of students.
