| In order to fulfill the requirements of the new curriculum standard of information science and technology in the compulsory education stage of 2022 and explore the effective teaching of information technology curriculum.In view of the problems of low quality,lack of science and purpose in the teaching of information science and technology course,it is necessary to change the teaching concept and explore the effective teaching to cultivate students’ subject thinking and ability.Effective teaching is the professional pursuit of teachers,and the application of class model plays a guiding role in the design of teaching process.Class model follows the principle and basis behind its design,which is scientific and instructive.Reasonable application can achieve effective teaching.First of all,combing the "effective teaching" and " class model " research development context and status quo.It is found that there are some problems in the application of class model in information science and technology,such as small quantity,shallow research and poor operability.The effective teaching of the subject of information science and technology is defined as the teaching of designing the teaching process with reasonable and effective teaching methods and means,guided by the core accomplishment of the subject of information science and technology,aiming at improving students’ knowledge level and deep learning ability and developing students’ necessary ability and emotional attitude for lifelong development in an all-round way.Effective teaching ultimately points to the promotion of students’ deep learning ability.After defining the research framework,the paper defines the core concepts such as effective teaching,class model,question scene,etc.And choose constructivism learning theory,effective teaching theory,situational teaching theory and teaching process optimization theory as the theoretical basis.Secondly,in order to ensure the feasibility of the implementation of the class model in the follow-up study,the Questionnaire of "Self-determination-Cooperation-Inquiry" is constructed.According to the result of investigation and data analysis,the students’ abilities of autonomous learning,cooperative learning and problem-solving are all above the middle level.Then,based on the principles of concrete,open,normative and systematic abstraction,the new curriculum standard and BOPPPS teaching model,the autonomous and cooperative inquiry curriculum is designed.And designed the stage test question,the curriculum study appraisal table,quoted "the deep learning ability scale",carries on the effect test to this curriculum in the effective teaching practice.Through large-unit teaching practice,the class model is continuously optimized and iterated by design research method.Through the effect test,the significant differences between the pre-test and post-test of the experimental class(P = 0.000)and the post-test of the control class(P = 0.005)were obtained,and the scores of the experimental class were 10.24 points higher than the average scores of the control class(P = 0.018 < 0.05).So we can draw a conclusion: the question inquiry class model under the effective teaching idea is beneficial to the promotion of students’ deep learning ability and achieves the effective teaching goal.Finally,we invite the front-line IT teachers to verify the operability of the course,modify the course according to the problems in teaching design and implementation,and interview the teachers before and after the teaching.Further perfect the class model,put forward the junior middle school information science and technology effective teaching implementation suggestion.Problem-inquiring class model is an operable class model designed for effective teaching of information science and technology.It has six elements and N links.Lead the students to carry on the scene analysis,the principle cognition,the application migration under the teacher sufficient pre-class preparation,the output study achievement.Achieve effective teaching objectives for information science and technology courses. |
