introduction

The Curriculum Standards emphasize the use of disciplinary concepts as the core, achieving structured and contextualized curriculum content, and promoting the implementation of core competencies. Daguan Nian can help solve the problem of fragmentation and superficiality in English teaching. This article explores the overall teaching design of high school English units based on Daguan Nian through case studies.

Analysis of the teaching materials

An in-depth analysis was conducted on the teaching content of Unit 4 Information Technology in the compulsory second volume of the high school English textbook published by Beijing Normal University. The teacher clarified the theme with "information technology" as the core by studying the various texts of the unit, sorted out the connections between sub themes, and constructed a thematic and linguistic perspective. The teaching objectives and steps are formulated based on this grand concept. The unit theme involves the function, influence and application of information technology. It aims to enable students to understand the impact of information technology on life, understand the connotation of network virtual image, explore the functions of commonly used apps, discuss the impact of the Internet on friendship, and learn to apply information technology to solve problems. The overall concept of English subject is the integration of language and thematic ideas. Teachers need to base their core competencies on in-depth reading of discourse, establishing connections between sub themes, refining small concepts, and summarizing thematic ideas. Through analysis, the teacher extracted the unit theme concept of "Reasonably understanding and applying information technology, enhancing information security awareness", and extracted the language concept from language and structural features, that is, "using vocabulary and expressions related to information technology to evaluate the impact of information technology from multiple perspectives". Ultimately, teachers construct a unit concept to promote the realization of educational values and the development of students' core competencies.

Analysis of students

An analysis of the learning situation of parallel class students in the first year of high school at a municipal demonstration school in Beijing was introduced. Students are familiar with the concept of "information technology", but have insufficient understanding of its development, application, and impact. In terms of language ability, students are able to extract and integrate detailed information from reading and listening, but their fluency and coherence in expressing viewpoints need to be improved. Students need to learn more English expressions related to information technology.

Unit teaching objectives

Set teaching objectives for high school English units, including: 1 Students analyze and discuss information technology and app functions, using actual apps as examples; 2. Students discuss the advantages and disadvantages of evaluating the use of virtual images and making friends on the Internet, and express their views using argumentation methods; 3. Students write online personal profiles, design apps, and solve practical problems.

Design of Unit Teaching, Learning, and Evaluation Activities

This article introduces the overall teaching design of high school English units based on Daguan Nian, emphasizing the importance of integrated design of teaching, learning, and evaluation. Teachers promote effective learning and ensure the achievement of teaching objectives by designing diverse teaching and evaluation activities, such as preschool diagnostic evaluation, formative evaluation, and summative evaluation. The design of teaching and evaluation activities progresses layer by layer, guiding students to internalize knowledge and language, and monitoring the learning process through evaluation activities. At the end of the unit, students form a correct understanding and attitude towards information technology by sorting out the theme meaning.

Summary and Reflection

Extract the concepts of unit size and detail to promote students' deep learning; Implement the integration of teaching, learning, and evaluation, with classroom evaluation running through the entire teaching process; Supplement unit supporting testing and optimize unit evaluation plan.
