| Issued by the party central committee and the State Council "on deepening the reform of education teaching opinions comprehensively improve the quality of compulsory education" strengthen the classroom main position,and improve the classroom teaching quality "、" accurate analysis,attaches great importance to the differentiation teaching and individualized guidance ",required to the education power focus on classroom teaching,mainly analysis the students’ learning needs,help teachers orientation,based on learning teaching,to fully meet the demand of students’ personalized development.Many teachers and teaching research personnel further strengthen the control of classroom teaching quality through the research and practice of teaching design,but there are still some situations in information technology course teaching,and how to strengthen the main position of students in the teaching process still needs in-depth research and exploration.Therefore,this study designed and practices the precision teaching based on preview sheet,aiming to explore the new path of precision teaching design and practice from the accurate analysis of learning situation,give play to the power of precision teaching,and promote the improvement of teaching quality.Research using literature research method analysis of the development of precision teaching and preview at home and abroad,the connotation of precision teaching and practice and preview sheet design application,and use the questionnaire method and interview method clear junior middle school teachers and students to the current precision teaching attitude and expectations,further illustrates the design and practice based on the importance of precision teaching.In addition,combined with the students ’needs of accurate teaching,teachers’ analysis of the current teaching situation of information technology courses and the design of preview sheet of Mazano’s new educational objective theory,the preview sheet provides students with preview guidance and self-test function of educational objectives,and positions the learning situation for teachers.Based on the learning situation reflected in the preview sheet,it helps teachers to design the precise teaching based on the preview sheet with accurate positioning of the learning situation,accurate classroom teaching and accurate after-school intervention as the main links.Subsequently,the experimental method was used to verify the application effect of accurate teaching practice based on the preview sheet.In the preparation stage of the experiment,compare the experimental class and the independent learning ability,and select the corresponding experimental class and the control class in the second grade of a middle school.In the process of the experiment,the precise teaching based on the preview sheet is applied to the experimental class,while the control class maintains the traditional classroom teaching dominated by the teacher.After the experiment,the same test paper was applied to test the scores of the two classes and compare the scale to test the change of the students’ independent learning ability in the experimental class.It is found that:(1)the implementation of precise teaching based on preview sheet plays a role in promoting students’ learning;(2)the implementation of precise teaching based on the preview sheet cultivates students’ independent learning ability;(3)the effect of precise teaching based on the preview sheet improves the performance has different performance in different categories of knowledge learning;(4)the use of the preview sheet helps teachers accurately analyze the learning situation.To sum up,precision teaching based on preview sheet plays a good role in helping students improve their performance,and can help teachers to accurately position the learning situation and construct accurate teaching classroom.However,there are also some deficiencies in the research,and further research is still needed in the setting and quantification of preview sheet. |
