Teaching Design And Practical Research Of Combination Of Educational Cases And Micro-video For Chemical Terminology In Ninth Grade Chemistry Education

As the era of the big data is coming,information technology has greatly develops.The progress of science and technology will necessarily promote the reform of teaching mode.While as an emerging education carrier,the emergence of micro-video provides for the educational reform.The educational cases are professional programs which are put forward by Prof.Cui Yunkuo of East China Normal University,emphasizing students' learning experiences,the implementation of educational cases push our country's educational reform towards a new level.The educational case and micro-video all propose to determine to learn to teach,achieving personalized learning,injecting the new energy into class,to enable students to enjoy learning and be fond of learning and promote teachers to enjoy teaching and be fond of teaching.Supported by constructivism,zone of proximal development and advance organizer strategy,the study firstly presents related literatures and development conditions of education case and micro-video with literature study method,finds out the integrating point of both,finding problems such as poor study habits and low classroom efficiency by the questionnaire survey which was conducted on the status of chemistry learning for junior high school students,to solve the above problems to design the teaching scheme combining education case and micro-video and then applies it to practical teaching to improve the chemistry learning status of junior high school students.It takes related knowledge in The Use of Chemical Terms in Volume I of Chemistry Textbooks of Grade Nine published by Educational Science Publishing House for example to carry out teaching design.Pre-class stage includes two parts,respectively are the teachers' preparation for teaching materials and students preview.In-class stage includes the sections of asking questions,self-regulated learning in the group,completing tasks by sharing out works andcooperating with others in the group,achievements presentation,feedback practice,concentrated problem solving,etc.After the class,the analysis of study results,questionnaire analysis and interviews of teachers shows that this kind of teaching scheme contributes to the training of students' self-regulated learning ability and the development of students' innovative thinking and cultivation of co-operation,and enables students to develop them physically and mentally and possess corresponding chemical attainments.In the meantime,the teaching scheme contributes to the teachers' professional development during application process and diversifies the teaching mode.
