A Key-Competence-Oriented Study On The Unit Teaching Design Of Information Technology Subjects In Senior High School

In recent years,the rapid development of new generation of information technology such as big data,Internet,and artificial intelligence has changed the way people produce and live.In order to meet the needs of social development for talent training,today’s education is more concerned about the cultivation of the core literacy of disciplines,and calls for innovation and reform of teaching methods.Unit teaching has become a key path for implementing core literacy training,and teachers are still difficult to carry out teaching in high school information technology units.The lack of simplicity,science,practicality,and reflecting the characteristics of information technology disciplines.In response to this practical issue,this study aims to build a teaching design method of high school information technology units pointing to core literacy training and gather typical cases.It is expected to provide a reference for the teaching design and practice of high school information technology units in front-line teachers.The main research method adopted in the study is design-based research,combining literature research method,content analysis method and survey research method,etc.The following work has been carried out: firstly,the relationship between the core literacies of IT subjects has been clarified,and a cultivation approach has been formed which takes the cultivation of computational thinking as the main line,digital learning and innovation cultivation as the basis,and links the balanced development of multiple IT core literacies;at the same time,the cultivation mechanism of subject core At the same time,the cultivation mechanism of subject core literacy is analysed,i.e.learners need to engage in three kinds of learning activities: learning and understanding,application and practice,and migration and innovation,to promote the transformation of knowledge into meaning,knowledge into function and knowledge into literacy,and to form subject core literacy;based on the analysis of the relationship between core literacy and cultivation mechanism,the cultivation path of senior secondary IT core literacy is clarified to include: firstly,to lead by core concepts and reconstruct learning contents;secondly,to clarify The core literacy of information technology in senior high school includes: first,to lead by core concepts and reconstruct learning contents;second,to clarify literacy objectives and create learning contexts;third,to use diversified approaches and set up smart teaching assessments;fourth,to focus on activity design and promote high access transfer;fifth,to highlight the characteristics of information subjects and create an interactive classroom with student subjects.Secondly,we summarise and follow the consensus of current research on unit teaching design,and determine the design framework of the high school IT unit teaching design that points to the cultivation of core literacy in this study.On this basis,the design method of high school IT unit instructional design for core literacy development was constructed by combining constructivist learning theory,Gestalt psychology,reverse instructional design theory and the path of core literacy development in high school IT,including six main aspects: identifying core concepts,reconstructing unit content,writing unit objectives,designing multiple assessments,creating unit themes and structuring activity processes.Finally,based on the constructed design method,we develop a high school IT unit teaching design plan with front-line teachers and carry out teaching practice.Through two rounds of practice iterations,the effectiveness of the design method for high school IT unit teaching directed at core literacy development constructed in this study is verified,and the design method is optimised and improved.The research results show that the instructional design method of high school information technology unit based on core literacy training constructed in this study can effectively help teachers understand the instructional design concept of high school information technology unit,clarify the design elements,guide teachers to design the instructional design scheme of high school information technology unit and carry out the teaching implementation.Through interviews and analysis of students’ digital works,it is found that the instructional design scheme developed by applying the design method has good teaching implementation effect,and can promote the cultivation of high school students’ core literacy of information technology.At the same time,it is found that the instructional design and practice of information technology unit in high school oriented to core literacy training poses challenges to teachers’ information-based teaching skills.Therefore,the study suggests that teachers’ collective strength should be given full play to carry out the instructional design and practice of information technology unit in the way of cooperation between teaching and research groups.
