Features: Physics is a discipline based on experiments, and every law in physics is derived from solid experimental foundations. In the various tests of secondary school physics teaching, the performance in experimental exams significantly affects the overall level of the subject. However, experimental teaching has always been a bottleneck in high school physics education, impacting students' ability to demonstrate their physics knowledge. The reasons are as follows: First, constrained by experimental conditions and teaching schedules in secondary schools, we cannot allow students to freely conduct experiments related to the formation of physical laws, explore and experience the process of their formation, or even extend the prescribed experiments. This greatly limits the true improvement of students' experimental skills and weakens their interest in learning physics. Second, although we complete the demonstration and student experiments as required by the secondary school physics teaching syllabus during experimental teaching, emphasizing standardized operation and nurturing students' experimental skills, the assessment of experimental abilities in exams is indirect, focusing more on experimental thinking and methods. The experimental questions students encounter are often derivatives and extensions of the experiments they have performed, leading to an imbalance between assessment and operation. Students feel uncertain and lost when facing experimental exam questions, unable to bridge the gap between laboratory experiments and exam questions.
To help students complete the student experiments prescribed by the syllabus and improve learning efficiency, the authors of this book have clearly defined its purpose: to enable students to not only successfully complete the prescribed student experiments at the lab bench and understand the demonstration experiments conducted by teachers in class but also to familiarize themselves with the experimental principles and methods embedded in each experiment. Additionally, it aims to facilitate a smooth transition from laboratory experiments to exam questions, thereby consolidating students' experimental skills while enhancing their exam performance.
To meet the needs of secondary school physics experimental teaching, the book is divided into four chapters:
Chapter 1: Fundamentals of Physics Experiments
The theoretical requirements for physics experiments in secondary school teaching are not very high, but each experiment involves certain methods of thinking and follows specific experimental principles. Based on the teaching syllabus and the college entrance examination syllabus, this chapter appropriately summarizes and elaborates on the theoretical knowledge involved in secondary school physics experiments.
Chapter 2: Basic Instruments
This chapter provides detailed explanations on the structure, principles, and usage methods of basic experimental instruments required in secondary school physics experiments, serving as essential reading for students before conducting experiments.
Chapter 3: Student Experiments
This chapter thoroughly elaborates on each student experiment prescribed by the secondary school physics teaching syllabus and the college entrance examination syllabus from the following aspects:
[Experiment Guidance] For students encountering the experiment for the first time, this section provides a comprehensive guide covering experimental objectives, principles, apparatus, procedures, data processing, error analysis, and key points to note during the experiment. It lays a solid foundation for students to complete the experiment quickly and efficiently, greatly aiding their understanding of new course content.
[Question Analysis] Around the experimental content, a selected number of exam-style experimental questions are analyzed and solved in detail. This not only helps students further understand the experiment but also extends the experimental content, serving as a bridge for students to transition from the lab to exam questions.
[Experimental Extension] Building on the main experiment, this section further extends the application of experimental methods and the functions of apparatus, guiding students to creatively apply the experimental thinking presented in the student experiments and elevate their experimental skills to a new level. At the same time, considering the characteristics of the college entrance examination's science comprehensive test, this section also takes into account interdisciplinary integration while expanding on physics experiments. Of course, these experiments are presented in exam-style formats, significantly strengthening students' exam-taking abilities.
[Exam Preparation] Based on the college entrance examination syllabus, 10 selected questions from past and mock exam papers are provided for students to practice. Although the number of questions is limited, they can help students achieve the effect of "learning one and understanding three," reinforcing and consolidating their learning outcomes.
Chapter 4: Introduction to Demonstration and Classic Experiments
There are many demonstration and classic experiments in secondary school physics classes. This section selects 22 representative demonstration and classic experiments that are easily transformed into exam-style questions, introducing the experimental process and objectives, along with relevant case analyses. This ensures students gain a comprehensive understanding of secondary school physics experiments and their principles.
Given the prominent role of physics experiments in secondary school physics teaching, the comprehensive nature of the content, and the strong independence between experiments, this book has collected a large number of new, design, and comprehensive experimental cases. Additionally, due to the authors' limited expertise and excessive focus on improving students' exam-taking abilities, there may be omissions and inaccuracies in the book. We sincerely welcome any constructive feedback.
