Development And Research Of High School Information Technology Experimental Textbook Based On Students' Cognitive Status

The "Ordinary High School Information Technology Curriculum Standards(2017 Edition)" clearly states: "The use of information technology laboratories to create real problem situations,to provide students with practical experience from information system design planning to hardware and software operations." And "information In the technical laboratory,through the experiments of 'Practical Internet of Things System Relying on Two-Dimensional Codes' and 'Remote Control System',students are instructed to cooperate or independently complete hardware construction and software installation of an information system."This study is based on the curriculum standard and develops high school information technology experiment teaching materials based on students' knowledge of relevant concepts.There are three research contents:(1)Students' cognition of certain core concepts in the “remote control system” What is the situation?(2)How to develop information technology "remote control" student experiment materials based on students' cognitive status;(3)How effective are the experimental materials developed in this way.Focusing on the above three research contents,this study first used the questionnaire survey method to investigate the content of two core concepts in the“remote control system” and investigate students' cognitive status.Afterwards,the basis for the development of experimental teaching materials based on students 'cognitive status was proposed,and the relevant theories of the teaching materials were used as a guide to organize the structure of the experimental teaching materials,including the structure of the teaching materials,the composition of the columns,etc.,and revised the teaching materials based on the trial results of the teaching materials.Finally,we developed a "remote control system" student experimental teaching material.Through the educational experiment method,the questionnaire survey method and the interview method,the students' knowledge acquisition before and after the teaching is tested.Through the comparison of the results before and after the test,the use of teaching materials,the filling of experimental reports,questionnaire surveys of satisfaction with teaching materials,and interviews were used to prove the validity of the teaching materials.The following conclusions were drawn from the study:(1)Students have different cognitive biases for “remote control” and “sensors”;(2)Based on students ' cognitive status and starting from the interface between the teaching materials and the students' cognitive status.Develop experimental teaching materials;(3)Experimental materials developed based on students ' cognitive status can effectively improve students' academic performance in this part.
