| With the development of the times,teachers and students are not as standardized as they were in the early days,and teachers no longer have authoritative personality.The ideas and goals of the new curriculum are constantly spreading,changing the original teaching ecology.In order to adapt to the wave of new curriculum reform,teachers continue to make changes in teaching.Heuristic,guided,cooperative teaching,learning community,group discussion and other teaching modes have emerged,breaking and improving the problems caused by traditional narrating teaching.With limitations.The main purpose of the research is to review the teaching effectiveness of the new curriculum through online video,and as a starting point of this research,analyze the open mathematics class through video analysis,find the problems and propose solutions.Online video plays a very important role in the process of student learning or teacher teaching.Such important resources reflect the quality of online video.In the past,it was difficult for us to notice the teaching problems in the classroom or the status of student participation,which led to the ineffectiveness of teachers 'teaching.Now,through online video,we can better understand the problems and blind spots in the teaching process,and then propose amendments Suggest.On the basis of qualitative research,the thesis selects representative videos from teaching for transcription analysis,and divides teaching into five levels:teaching process and teaching time,teaching interaction and teaching problems,and teacher language,using video analysis method,Conducted specific quantitative research and analysis of classroom video.This research uses video analysis to study the status of classroom teaching of open mathematics classes in online high schools.By searching online videos of mathematics courses,the research scope is the teaching status of mathematics classrooms,and the research methods are comparative research and video analysis.The reason for choosing online public courses is that online public courses provide convenient learning methods for today 's in-service teachers and pre-service teachers,and teachers in remote areas or areas with weak education can also easily observe and learn.After analysis,it was found that during the teaching process of the online high school mathematics teaching video,the teacher's explanation will be quite detailed,and will also summarize the teaching content.The teacher is also very patient and the class discipline is also very good.Even so,there are still the following problems:Firstly,teachers' teaching concepts and methods do not match the teaching concepts of the new syllabus,and there is still a big gap.The teaching process cannot be adjusted according to the actual needs of the students,which reduces the student's subjectivity and at the same time fails to stimulate the students' mathematical thinking ability and the cultivation of inquiry spirit.Secondly,the teaching aspect of network teachers is mainly based on the teaching method,lacking interaction and enlightening problems with students.Thirdly,the students' motivation is quite low,their willingness to learn is low,and they lack self-confidence.The students are silent when they ask the teacher in the classroom.Be monotonous and dull.The results of the study found that there are many problems with open courses on the Internet,but they are still important channels for remote areas or pre-service teachers to observe and learn.After studying the video teaching of high school mathematics network open courses,it is believed that further improving the mechanism of network open courses is of practical significance for achieving a high-quality dialogue between teachers and students.In the future,it will provide support for teachers to better grasp classroom interaction. |
