The Effect Of Image Processing Topical Teaching Micro-video On High School Students' Operation Ability

The fast evolvement of the Internet industry has led to the fast evolvement of modern education technology.The various types of digital products that are generated have infiltrated into the production and life of human beings,have a profound impact on the field of education,and further promote teaching reform With the development of education informatization,in order to create an informational environment full of high-quality teaching resources for students,educational researchers began to pay attention to how to use modern education technology to realize the informatization of various subject teaching.Micro-video teaching resources have quickly become one of the hot spots of educational research in the context of the development of the digital age,with its advantages of short and sturdy,highly targeted,not limited by time and space,and repeatable learning.The high school information technology discpline not only pays attention to the students' theory,but also pays attention to students' practical operation ability.Skills lessons are no longer limited to editing documents,creating basic capabilities such as forms and presentations,and involving the cultivation of algorithmic thinking,web page design,database,and image processing and other related operational skills.At present,the status quo of the teaching of the course still has defects in varying degrees.In information technology skills courses,there are common problems such as a single teaching method,poor teaching results,and the inability of students to operate.Thereffore,the author tried to use the topic-based teaching micro-video to improve the student's operational ability in the high school information technology course "Photoshop Image Processing".First of all,the author interviewed and investigated the current teaching situation of the Photoshop Image Processing course in the information technology course of the First Affiliated Central China Normal University,and thoroughly understood the deficiencies in the teaching process of the course.Secondly,the author through the in-depth study of constructivist teaching theory,in-depth study of multimedia learning theory,based on a more standardized instructional micro-video design and production principles,designed and produced a"photograph/teaching card" as the subject of photoshop teaching micro video.In the end,after the preliminary investigation,the author selected two classes that are equivalent to the school's level as experimental subjects and implemented traditional teaching and special micro-video teaching respectively.Among them,the traditional teaching is mainly to learn the individual tools of the image processing software one by one.At the beginning of the teaching process,the teacher explains and manipulates one or more software tools on the teacher's machine,and then sends the operating points to the students in text form.The students begin to practice what their teacher have taught.The topical teaching micro-video is the system learning background production,text production as the content,teachers complete the classroom after the introduction of the students to watch video learning methods.In the entire experiment process,the two points of teaching knowledge are the same before and after.After the experiment is completed,the students' work is collected and the corresponding scores are given according to the operating skill evaluation scale.The results are analyzed in order to provide some reference for the future photoshop course teaching,and to explain the lack of research and future research direction.
