Teaching Design And Application Of IPad-based Biological Smart Classroom In Junior Middle School

Information technology in the Internet age has a revolutionary impact on promoting educational development.After the promulgation of the Outline of the National Medium and Long Term Education Reform and Development Plan(2010-2020),the strategic position of information technology in the national education development has been determined,and the integration and application of modern information technology and subject teaching has become an inevitable trend.From the beginning and application of information technology to the deep integration with classroom teaching,smart class,a new form of classroom development,has emerged in the classroom of the information age.How to better carry out the smart class teaching and improve the teaching effect in the campus has become one of the focus of teaching research.In order to optimize the smart class teaching of biology in junior high school,in this paper,the investigation method,action research method and other research methods are mainly used.On the basis of literature review,this paper takes 145 students and 14 teachers of a middle school in Hohhot as the research object,and explores the theory and practice of smart class teaching design of biology in junior middle school.The main work and results are as follows:Firstly,through the investigation of the status quo of the application of smart class in junior middle school biology in the author's practice school,all the teachers and 89%of the students in the survey are found to have a recognized attitude towards the teaching method of smart class based on tablet.But in the teaching of current campus smart class,there are still various problems and deficiencies in network,equipment and teaching,including poor network stability,imperfect tablet function,students'classroom attention is easily affected by the tablet,teaching design despises the pre-school and post-school stages,etc.Secondly,based on the above problems and relevant theories of instructional design,the author mainly studies the application of smart class in biology subject based on ipad from the aspect of teaching design.The teaching design is based on the curriculum standards,the content characteristics of teaching materials and the current information technology of smart class.The teaching design principles are the data-based diagnosis of learning situation,the diversified interaction between teachers and students,and the timely evaluation and feedback.Moreover,in accordance with the"Three-stage"teaching sequence before,during and after class,this paper attempts to design the teaching design process of the common course types(new teaching,experimental class,review class)of the junior high school biology smart class,and implements the corresponding cases around the content design of the first volume of the seventh grade biology of the Pep edition.Furthermore,after the implementation of smart class in the experimental class,the following findings are obtained:the first is in the aspect of learning experience,the proportion of students who think that they can communicate well with teachers in class has increased from 37%before the experiment to 75.9%,showing a significant difference before and after the experiment(χ~2(28)23.036,p<0.01).The second is learning efficiency.The proportion of students who attach importance to preview before class has increased from 62.9%before the experiment to 94.9%,showing a significant difference before and after the experiment(χ~2(28)46.039,p<0.01).The proportion of students who concentrate in class increased from 66.7%to81.5%,showing a significant difference before and after the experiment(χ~2(28)31.027,p<0.05).The third is the learning results.The proportion of students who have a good command of classroom knowledge has increased from 64.8%to 79.6%,showing a significant difference before and after the experiment(χ~2(28)28.314,p<0.05).But the proportion of students who think that they have enough time to think independently in class has increased from 85.2%to 70.4%,showing a significant difference before and after the experiment(χ~2(28)31.604,p<0.01).Besides,this paper also found the following in the research process:the smart class is conducive to class-level teaching and reduces students'learning gaps.The research finally shows that:from the aspects of learning diagnosis,exchange and interaction,evaluation and feedback,the smart class of junior middle school biology optimized for different course types has a positive role in improving learning experience,improving learning efficiency,and promoting the mastery of knowledge in learning results.However,the promotion of students'independent thinking ability has not been confirmed.The reason may be that the design of gradient and difficulty is unreasonable.Therefore,in the future,we should do further research and practice in the aspect of rational design of problems to promote the effective implementation of smart classroom.
