What does the unit big concept architecture mean?

The connotation of the big concept of the unit.

a) Big Concept.

Big concepts, also known as big concepts, refer to the core concepts that are abstracted on the basis of facts, can explain and improve a large range of things and phenomena, covers basic knowledge and basic skills, and helps learners understand and understand the world.

2) The big concept of biology.

The "big concept" of biology is the core concept of the discipline, which is in the center of the discipline, reflects the essence of the discipline, embodies the core educational value of the discipline, is the concentrated embodiment of the discipline's thinking, discipline knowledge and discipline ability, and is the foundation and essence of biology. Biology can be regarded as a collection of multiple big concepts, which build the basic framework of the discipline and can build the knowledge system of biology through big concepts. Big concepts are an important part of the concept of life.

This study is based on the perspective of biology education, so the major concepts mentioned at the end of this article are defined above.

3) Unit teaching.

Professor Cui Yunmiao believes that a unit is a learning unit, and a unit is a learning event and a complete learning story. There are different perspectives and different levels of knowledge and understanding of the unit. It has been proposed that the size of the unit be determined based on the size of the scope of the core content of the unit.

The author believes that the unit we are discussing about teaching should be a teaching unit based on teaching activities, from the content of the teaching unit can be large or small, its size depends on the theme around, if the theme around is a small factual knowledge, then the unit can be a micro-lesson, if the theme around is larger, such as cell structure, then the unit contains many class hours. The teaching unit of the article refers to the thematic unit based on the big concept of high school biology.

This kind of teaching unit is also more in line with the principle of "less but fine" and highlighting the key points pursued by the "Curriculum Standards". Teaching units are structured units around a topic or task based on big concepts. There is a rigorous logical structure between the various parts of the unit, and the local content is interrelated and mutually supportive, highlighting a theme, which is different from the chapters of traditional textbooks.

Therefore, the construction of teaching units should refer to the knowledge framework of their own disciplines, but they do not have to stick to the ready-made chapter division in the textbooks, but should integrate, rationally transform and rationally utilize the textbook resources according to the actual needs. Unit teaching is a method of integrating teaching materials and teaching resources around a certain theme, and it is a teaching strategy and teaching philosophy.

4) Unit teaching design.

Unit teaching design is the design of how to carry out unit teaching, which is based on a certain theme, fully considering the relevance and integrity of the relevant content, the cognitive characteristics of students, and the design of the learning process of advanced learning.

1) Refinement of discipline core literacy. Implement the discipline curriculum standards, deeply understand the core literacy of the discipline, correctly understand the essence of the discipline and the core value of the discipline, clarify the necessary knowledge, key abilities and comprehensive literacy of the discipline, and refine the correspondence to the unit, refine and summarize the major concepts of the unit, and scientifically set the learning objectives of the unit. (2) The conceptual structure of the unit.

According to the extracted unit concept, the unit knowledge structure system and thinking ability under the leadership of the unit concept are constructed.

Advanced sequence and subject literacy cultivation path, design an integrated system of unit learning objectives, classroom teaching, student learning and evaluation feedback, and provide students with necessary learning scaffolds and learning resources. (3) Perspective of the overall teaching process. Based on the curriculum standards, the content of the textbooks and the cognitive characteristics of students, the teaching schedule, teaching process, teaching activities and teaching resources (or the integration and reconstruction of the content of the textbooks) are scientifically designed, so as to run through the whole process of unit teaching with the big concept of the unit, and reflect the specific process of students' acquisition and thinking advancement.

Teaching flow charts can be used when necessary.

or structure diagram rendering. (4) Design of the specific content of the homework. According to the learning objectives of the unit and with reference to the evaluation criteria, the specific content of the unit assignment is designed as a whole, and typical problems, tasks or activities are designed with real or realistic and specific situations as the carrier, reflecting the basic, comprehensive, applied and innovative characteristics of the assignment, and promoting the cultivation of students' ability to solve real problems. At the same time, the specific intent of the assignment content design is explained, including the necessary knowledge, key competencies and core competencies contained in each assignment.

Summary. The overall teaching of the unit based on the big concept refers to the construction of a complete teaching unit led by the main theme of the unit, the interrelated and logical themes of each discourse, so that the teaching can set the unit objectives around a complete theme, and guide students to gradually construct the big concepts based on the theme of the unit based on the learning and refining of the small concepts of each individual discourse. Therefore, the overall teaching design of the unit based on the big concept is helpful to help teachers grasp the essence of moral cultivation in teaching, focus on the construction of the meaning of the theme, plan the integration of teaching, learning and evaluation as a whole, and promote the integrated development of students' core literacy.

The big concept is a deep-seated, meaningful, and transferable core concept, pointing to the more essential content behind the specific knowledge of the discipline, and reflecting the thinking mode and core viewpoint of the discipline. The big concept is the embodiment of the core knowledge ideas and values of the science of science and technology, and it is an important starting point to guide students to implement deep learning.

The overall teaching of the unit based on the big concept refers to the construction of a complete teaching unit led by the main theme of the unit, the interrelated and logical themes of each discourse, so that the teaching can set the unit objectives around a complete theme, and guide students to gradually construct the big concepts based on the theme of the unit based on the learning and refining of the small concepts of each individual discourse. Therefore, the overall teaching design of the unit based on the big concept is helpful to help teachers grasp the essence of moral cultivation in the teaching of Xuchiyu, focus on the construction of the difference rock structure with the meaning of the theme, and plan the integrated activities of teaching, learning and evaluation as a whole, so as to promote the integration and development of students' core literacy.
