frameless magnetic whiteboard. The teaching design involved in this project is different from the complete teaching system design. Compared with the development of the entire teaching system, we pay more attention to the design of daily classroom teaching. In the early stage of the experiment, due to the limited mastery of the new technology and new ideas, the teachers are generally assisted by the teaching design experts; in the analysis of the learning objectives and learning content, due to the daily classroom teaching in primary and secondary schools. All learning activities are carried out according to the syllabus and designated textbooks. Therefore, the new curriculum standards and new textbooks currently implemented in basic education can be used as the basic basis for teachers' teaching design. In the analysis of students, students in primary and secondary school classrooms The relationship between teachers is relatively fixed, and teachers have a full understanding of the students' general characteristics, learning style, initial ability and individual differences. Therefore, the connotation of the instructional design we mentioned here can be summarized as follows: in the case of the syllabus and the goal of teaching, in order to promote students' learning, teachers use systematic methods to plan classroom teaching or unit teaching in different teaching environments. process.. The IQAio GR519 is an upgraded lightweight version based on the original IQAio GR511. The original dual-cavity structure was changed to a bottom-edge structure, so that the minimalist design accommodates modern classrooms and conference rooms. With one IQProjector V2 and one IQView E3821, you can achieve flexible and intelligent classroom.
