A Study On The Three - Stage Teaching Of "Perceptual Construction - Application" Under Network Support

Today, With the rapid development of information technology, Network, digital, intelligent learning environment for students to cultivate innovation capability provides better conditions for support. This is catered to the goals and objectives of elementary education curriculum reform which explicitly put forward the cultivation of student’s creative ability, problem-solving ability and practice ability. But, the global knowledge innovation teaching research is developing, teaching practice under the network environment in some parts of China is still in the experimental stage of exploration, How to build the teaching theory under the network environment, how to effectively digitize teaching activities, how to assess changes in teaching and learning, all of which need to practice as a pilot study. This study is based on the practical demand of" The teaching experiment project under the environment of network and digital" in Nanjing, which selects the mathematics in a junior high school to carry out the practice of changes in teaching way under the support of the network, the purpose is:Try to combine new theory both at home and abroad, and construct the theoretical framework of the new teaching mode; Try to apply the new design frame to mathematics teaching, and then, promote the transformation of teaching and learning in teaching practice; Using a variety of means of empirical research, try to analysis the impact of the new teaching mode on student’s learning attitude, classroom teaching features as well as students grade.Study, first of all, starts from the present situation and problems of the present mathematics teaching, combining literature research and practical experience, analyses from the theory guidance, technical characteristics, the teachers and students,and so on, designs a "perception-construction-application" three stages of teaching design framework; Secondly, according to the actual situation of research target, contents and participants, teacher implements the three-stage teaching, try to analysis the impact of the new teaching mode on student’s learning attitude, classroom teaching features as well as students grades. Research methods mainly adopts participatory classroom observation, questionnaire and teacher interview, the original analysis data is mainly from videos, questionnaires, academic records, interviews, and other channels. The conclusion from the data statistics and analysis is:In terms of learning attitude, the students’learning attitude improved after carrying out the three-stage teaching, especially the part of learning behavior is significant, the factors in forming the change are diversified communication, multi-channel interaction and Intelligent practice; In terms of characteristics of classroom teaching, the classroom of the three-stage teaching is more tend to equality between teachers and students, technical support, open, cooperation, explore diversity; In terms of grades, the three-stage teaching enhances the student’s academic record significantly, there are more students enter the range of outstanding students, thanks to the learning atmosphere of democracy and freedom and the transformation of the students on the way to learn, which makes students become the real master.As the pilot research of "The teaching experiment project under the environment of network and digital" in Nanjing, the study can provide help for subsequent advance of knowledge innovation learning, also for the researchers who’s reforming teaching experiment.
