Features: With the continuous deepening of curriculum reform in basic education, people are increasingly recognizing the crucial role and sacred mission of teachers in curriculum reform. Teachers' understanding and participation in the new curriculum are the prerequisites and foundation for its implementation, and they will ultimately determine the direction of the new curriculum's implementation and the depth of quality education advancement. In a certain sense, teachers are the most important curriculum resources. The quality of teachers and their level of professional development determine the identification, development, and utilization of curriculum resources, as well as the level at which the benefits of the new curriculum standards and new textbooks should be realized. Currently, the state of teaching staff in China's basic education field cannot effectively keep pace with the large-scale expansion of curriculum reform. Short-term general training and limited training on new curriculum standards and new textbooks only serve to guide and provide direction for teachers. In the context of classroom-based teaching, teachers must adopt new concepts, use new curriculum standards and new textbooks, enter the classroom, and face all students to deliver high-quality lessons in practice. They will encounter various confusions and difficulties, such as the scarcity of new teaching materials, how to prepare lessons, how to organize teaching, how to conduct teaching evaluations, how to carry out teaching research activities, and how to innovate traditional teaching methods. As curriculum reform has developed to this stage, teachers must fully leverage their subjective initiative, deeply understand and experience the essence of the new curriculum standards in teaching practice, fully grasp the new textbooks, and continuously reflect on teaching to improve teaching practices. Only in this way can the requirements of curriculum reform be implemented. To help frontline teachers quickly adapt to the new curriculum reform and effectively use the new curriculum standards and new textbooks, we have organized the writing of the "Strategies for Teachers' Lesson Preparation under the New Curriculum Standards and New Textbooks" series. With the actual needs of teaching and teachers as the starting point, the series provides assistance and services to teachers in teaching by interpreting teaching objectives, creating teaching scenarios, providing teaching materials, showcasing teaching cases, and improving teaching evaluations.
I. Principles and Requirements for Writing
This book is written under the guidance of advanced educational ideas and the concepts advocated by the new curriculum, aiming to promote the implementation of curriculum standards across disciplines, deepen the implementation of quality education, and promote the development of educational research, especially school-based teaching research activities. It seeks to promote teachers' professional development, improve their practical teaching abilities and levels, and enhance the quality of education. The writing of this book emphasizes four unities:
1. Systematicity and Scientificity
This series is written by discipline, and each discipline follows the content of the first-level and second-level themes of the curriculum standards, combining the core knowledge systems of various versions of textbooks to structure the book in units. Each unit begins with an overview, emphasizing the systematic network of knowledge, the original perspective, and the comparison with the new curriculum standards. The series uniformly sets up columns, with each column providing scientifically accurate knowledge content, systematically clear teaching objectives, scientifically reasonable activity designs, practical and novel scenario creation, and detailed and reliable quality selection.
2. Practicality and Feasibility
The writing of the book establishes a service-oriented awareness for frontline teachers, effectively addressing difficulties teachers face when preparing lessons, such as finding materials, collecting resources, designing activities, and creating scenarios, thereby reducing their workload. Unlike general teaching reference books, this series comprehensively covers the needs of teachers when preparing lessons, serving as an indispensable assistant and guide for teachers. The writing fully considers the current state of teaching staff, students, teaching design, and various educational resources in China, making the series highly practical. Teaching requirements, activity designs, and scenario creation all take feasibility into account.
3. Timeliness and Innovation
When writing by discipline, attention is given to the new trends in educational reform at home and abroad, striving to stay at the forefront of curriculum reform in basic education. The content and materials selected closely connect with the development of politics, economy, science, technology, culture, and education in China and the world, reflecting contemporary demands. Innovation is emphasized, from content to form, from knowledge presentation to question design. The three-dimensional educational objectives of "knowledge and skills, processes and methods, and attitudes and values" permeate the entire book.
4. Inquiry and Leadership
When writing by discipline, attention is given to the professional leadership role of teachers, helping them broaden their knowledge horizons, enhance practical abilities, and guide and encourage them to conduct educational research. It advocates a spirit of scientific inquiry, promotes research-based learning, and strengthens the evaluation and reflection of teaching. The selection of content in each column and the allocation of various questions reflect foresight and leadership, appropriately increasing inquiry-based, open-ended, applied, and comprehensive topics.
This series is the crystallization of collective teaching research in curriculum reform.
II. Writing Format and Column Descriptions
This series is written by discipline, including nine subjects: Chinese, mathematics, English, physics, chemistry, biology, moral education, history, and geography. The book uniformly sets up six columns:
1. Interpretation of Teaching Objectives
According to the unit content of the new curriculum standards, teaching objectives are interpreted from the three-dimensional perspectives of "knowledge and skills, processes and methods, and attitudes and values." From the professional height of the discipline, the knowledge network structure and its internal connections are explained in an accessible manner. Necessary explanations are provided in conjunction with specific issues or examples, providing a detailed analysis of teaching key points and difficulties, highlighting the key points for solving key issues and breakthroughs, and strengthening the requirements for ability and quality development.
2. Suggestions for Activity Design
This column provides all necessary activity designs for the unit teaching (also including teaching content ideas, teaching flowcharts, and knowledge links, etc.). To implement teaching objectives and enable students to actively participate in teaching activities at multiple levels, forms, and angles, achieving efficient and high-quality classroom teaching, this book strives to help teachers design all teaching activities in each unit through effective lesson preparation. Since each unit teaching consists of several teaching and learning activities, only if each activity is designed scientifically and reasonably and is easy to operate can the optimization of the entire unit teaching be guaranteed. When designing teaching and learning activities, two aspects are considered based on the unit knowledge content:
- Classroom activity design (e.g., creating teaching scenarios, equipping teaching tools, multimedia-assisted teaching, student cooperative learning, teacher-student interactive activities, instruction and practice activities, experimental operations, etc.);
- Extracurricular teaching activities closely related to teaching that should be designed for the unit, such as research-based learning activities, experimental inquiry activities (e.g., after-school small experiments, home small experiments, laboratory operations, experimental design, small inventions, small creations, etc.), surveys and interviews, information collection, literature retrieval, social practice and community service activities, etc.
The design of activities strives to maximize the use of various educational resources and mobilize the learning enthusiasm of students at all levels. Through the development of teaching and learning activities, students become active participants and constructors of knowledge.
3. Reference Teaching Materials
This column provides relevant textual materials for unit teaching for teachers, such as background materials, introductions to figures, major events, relevant data resources, scenario materials, supporting examples, the latest developments, and historical evolution. It also recommends relevant books, network resources, and audio-visual materials.
4. Introduction to Teaching Cases
This column provides several teaching cases around the key content of the unit, reflecting the characteristics of various teaching types (e.g., new teaching lessons, problem-solving lessons, review lessons, experimental lessons, revision lessons, activity lessons, inquiry lessons, etc.). It emphasizes the design of various student activities, demonstrating a reform-oriented awareness in lesson preparation, and closely follows three threads:
- The thread of knowledge networks;
- The cognitive thread that aligns with students' psychological activities;
- The developmental thread of ability and quality cultivation.
5. Classic Question Selection
This column provides supporting questions for teachers' lesson preparation. When selecting questions, attention is given to difficulty gradients, striving for typicality and novelty, and ensuring each question is well-designed in terms of purpose, scenario, and question setting. The number of questions is moderate, and subjective and objective question types are determined based on the unit content of the discipline.
6. Teaching Evaluation Suggestions
Evaluation has diagnostic, guiding, and motivational functions. This column provides ideas and methods for teachers to conduct various forms of teaching evaluation.
(1) Basic Achievement Evaluation
Each unit teaching is accompanied by basic achievement test questions, designed according to the requirements of basic knowledge and skills on a percentage basis. If the average test score of all students is below 60, it is considered that the basic teaching objectives have not been met. If the average test score is between 60 and 74, it is considered that the basic teaching objectives have been met. If the average test score is between 75 and 89, it is considered that the basic teaching performance is good. If the average test score is between 90 and 100, it is considered that the basic teaching performance is excellent.
(2) Ability and Quality Evaluation
Ability and quality evaluation mainly focuses on students' basic qualities, specialized qualities, and comprehensive practical and innovative activities. Based on the unit content of the discipline, corresponding requirements for ability and quality items are proposed for students, such as experimental operations, creation, production, drawing, investigation reports, material analysis, thematic discussions, presentations, speeches, audio-visual skills, and talent demonstrations, etc. Each test evaluation result is rated as excellent, good, qualified, or basically qualified.
(3) Teaching Reflection
Teaching reflection is essential for teachers in the evaluation process and plays a significant role in improving the effectiveness of teaching and learning. For example: reflections on easily confused content for students, improvements in lesson design, improvements in classroom teaching, new problems discovered in the teaching process, reflections on test results and other feedback information, as well as insights into the unit teaching, etc. Teaching reflection provides teachers with broad space for professional development.
Finally, we sincerely hope that educators and frontline teachers across the country will join us in the tide of basic education curriculum reform, set sail for the shore of hope, and reach the desired destination together.
