I did encounter many difficulties in attending this intermediate training course online. Because I want to be a team counselor, a sixth-grade class teacher and a Chinese teacher. In addition, troops will be sent in the near future, and the guard of honor will be trained every day; Schools should accept the evaluation of moral education schools in the district, do a lot of moral education files, and attend public classes; It is also necessary to complete the tasks of the "clean" activities of the Municipal Youth League Committee; Besides, I also have some physical problems. All this is tantamount to adding insult to injury in training. At the beginning, most of my homework was copied from others (forced). Later, with the tolerance of Mr. Cen, I started my real study. Although it is very tangled (a lot of homework is finished in the middle of the night), this training and study also benefited me a lot: (1) During the case analysis, I was exposed to many teaching theories, which opened my eyes. I believe that the study of this network intermediate training class will be of great help to my future teaching career. In particular, the Educational Technology Reference Manual will accompany my educational career and give me lifelong help. (2) After finishing the homework in Module 2, I finally have a deeper understanding of inquiry learning, how to make inquiry learning plans, and how to guide students to carry out inquiry learning. This is the most precious and valuable. (3) By studying the process of making an action plan, I further understand that making an action plan with clear goals, clear thinking, simplicity and practicality, reasonably arranging working hours and forming an orderly working style will greatly improve work efficiency, and I no longer need to run around all day. (4) Through training, I have clearly distinguished the two concepts of educational technology and information technology. Educational technology must be based on information technology, but it is different from information technology. Technology in educational technology includes tangible technology and intangible technology. Tangible technology is the support of educational technology, while intangible technology is the soul of educational technology. The effective application of educational technology is to reasonably select tangible technologies under the guidance of advanced educational ideas and theories, organically combine them and apply them to practical teaching. Information technology refers to all technologies that can expand the functions of human organs. In our daily education and teaching, we should reasonably use modern educational technology to add interest to our classroom and lay the foundation for our education and teaching to achieve good results.
