In 2022, the physical examination papers of the Harbin High School Entrance Examination were based on teaching materials and guided by new physical curriculum standards. They insisted on paying attention to the foundation, strengthening applications, and cultivating ability. Based on the new developments of the current primary school physical propositions On the basis of strengthening the examination of students' physical knowledge application and experimental inquiry capabilities, the test papers have a focus on dual base and strengthen conceptual understanding; connect with life, pay attention to the use of knowledge; read data, focus on ability training; explore experiments, highlight process methods; Open integration, present the characteristics of physical characteristics. While examining and diagnosis, it reflects the orientation of people and achieves the leadership of front -line teaching. The proposition adheres to the newness of seeking newness, showing a new state in terms of propositional intentions and examination forms.

There are three major characteristics of this set of test papers:

The first is to especially emphasize the examination of "experiment and scientific inquiry". Experiments are the basis of physics, and inquiry is an important method of learning. The topics and scores that are closely related to experiments and inquiry contacts have not changed compared with previous years, but the guidance intention of the test paper is very obvious.

The second is to respond to the impact of the epidemic, integrate the reform of the entrance examination, and at the same time, in the "double reduction" environment, pay more attention to the examination of the double foundation, and the test questions are difficult.

Third, in order to promote the improvement of scientific literacy, return to the discipline, and strengthen the openness and flexibility of the test questions. Reduce the phenomenon of hard back and mechanical brushing, highlight the subject characteristics, focus on examining experiments and inquiry skills and language standards, and deepen scientific thinking, thereby strengthening the examination of key capabilities and discipline literacy, enhancing the application of test questions, and the application of test questions, and the application of the test questions, the application of the test questions, and the application of the test questions. Innovation, openness and flexibility, this has also increased the difficulty of examination to a certain extent. The gap between students with different levels of ability will be distinguished by the middle school entrance examination, which fully reflects the selection function of the middle exam questions.

1

Pay attention to the comprehensive examination of basic knowledge and basic skills, examine basic knowledge and basic skills flexibly, and guide teaching to promote the effective learning of students.

For all students, highlight the examination of basic scientific quality. In the setting of the choice questions, from the evaluation of 16 questions, to the application of electrical and magnetic applications, and the comprehensive option of 27 questions, the blank questions are based on the test of basic knowledge, basic skills, basic processes and methods. Pay attention to the test of the main knowledge and core content of the physics discipline.

The content covers a wide range of sound, covering the occurrence and dissemination of sound, the prevention of noise, the direct spread of light, the reflection of light, and the refraction of light; There are material changes, hot machines; home circuits, electrical and electrical power, Ohm law, electromagnetic phenomenon and other core content.

Basic questions highlight students' understanding and use of basic concepts and basic laws, avoiding the simple reproduction and memory of knowledge, which is conducive to the comprehensive development of students, and has a good guidance for physical teaching. In particular, the difficulty of choice questions is moderate, covering a wide range, clear layers, and reasonable layout.

Pay attention to the selection of materials from the actual situation, examine the ability of students to extract information, analyze and process information in actual situations, and guide teaching to contact students' lives and the development of social reality, and focus on the development of science and technology.

Not only does the background material connect with reality, but also highlights the application of the test questions. In the examiner of the 48 -question plane mirror imaging experiment, the examination of the image is dark after the reflection imaging, and in the 49 -question quantity to explore the internal pressure and depth of the liquid, emphasizes the use of students to encourage students to connect with the actual situation. Emphasize the emphasis on the usual experimental teaching, and the new phenomenon found in personal experiments, and experience the application value of the content of the classroom. Using the knowledge learned in the new discovery is the idea of ​​the proposition. Set up different knowledge and task situations, and examine experimental inquiry ability and innovation ability.

Pay attention to the examination of scientific inquiry ability, guide teaching to focus on the inquiry process and methods, and focus on cultivating students' ability to scientifically understand things, analyze phenomena, and grasp the laws. Further strengthen the examination of experimental operation capabilities to guide schools to attach importance to experimental teaching.

The entrance examination emphasizes innovative thinking and experimental inquiry. Innovation requirements create novel issues, so that candidates can actively think in novel situations, complete the inquiry or open tasks, aiming to guide students to return to the essence of physics, strengthen experimental teaching, and promote the core literacy of student disciplines from multiple perspectives. develop. For example, the 51st question papers should explore the relationship between electric power and voltage, but in the experiment, the new problem is combined with existing knowledge. The two resistance resistance values ​​are not much different. The two experiments of the heat absorption ability are combined, and at the same time use the density formula to find the quality, and comprehensively examine the students' language expression and logical thinking ability. It is required that these issues require students to analyze and organize language to interpret them in conjunction with the experimental results, which is slightly more difficult. It reflects the main purpose of examining the core literacy of student physics.

Pay attention to the guidance of the exam. The test propositions are conducive to guiding teachers to improve teaching and guide students to learn to learn. Examination proposition helps reduce students' academic burden and promote quality education.

In short, this set of test papers is close to the actual life of students. Pay attention to combining physical knowledge and research methods with social practice and their applications, which reflects the concept of curriculum from life to physics and from physics to society. Strengthen the examination of students' experimental ability, which is conducive to the students' innovative spirit and practical ability; pay attention to the examination of students' scientific inquiry ability, not only examine the comprehensive scientific quality of students, but also reflect the curriculums that promote the diversified learning methods of classroom teaching. Requirements; the test questions have strengthened the curriculum reform. Through the setting of openness and practicality, it highlights the examination of students' learning methods and abilities, which is conducive to promoting the sustainable development of students. Essence Chemistry: Contact the actual innovation situation of life

High shadow

The leader

In 2022, the chemistry test questions of the Harbin Municipal Entrance Examination gives full play to the characteristics of chemistry, selecting test questions, innovative presentation forms, and optimizing the way of setting up questions. Highlight the foundation, reflect science, and focus on innovation. Not only to examine the degree of basic knowledge and basic skills, but also pay attention to evaluating the level of students' scientific inquiry ability and practical ability. Pay attention to the development of scientific and technological development and social progress, and continue to highlight the chemical propositions of "changes" and "innovation". There are high requirements for students' knowledge migration, flexible response ability, and thinking processing ability.

Lead the core value and guide the Lide people

The test questions are based on the development of student development, the people of Lideshu, and the core literacy improvement of chemical disciplines. They pay attention to the development of students in terms of emotional attitude and values, fully respect the students' emotional experience and personality differences, focus on experimental processes, examine the inquiry ability, and the ability to explore and explore. The discipline characteristics are distinct, and the role of the chemistry discipline is fully played.

Based on basic knowledge and highlight the main content

The test questions examined the key content and core knowledge of junior high school chemistry. While examining the basic knowledge and skills of students, highlight the testing of the main content of the main content. Selected questions and previous exam questions are consistent with the content of the examination, and the basic knowledge grasp of students is inspected. 30 Questions are about micro -processes of hydrogen and oxygen reactions, and solve the essence of the proton number and chemical changes of water molecules. 32 Questions examine the related content of oxygen and carbon dioxide. This test does not avoid or repeat the question type of the main knowledge and the questions in the past years. It is not deliberately high. There is a distinguished test questions in the question method.

Contact the actual situation of life, detect the application ability

The test questions are closely connected to the students' daily life, which is closely linked to the progress of human health, life, production, and social progress. For example: Question 15 is about the solution of calcium element content in "calcium carbonate with calcium carbonate"; 28 questions examine the category of polyester materials, the types of nutrients rich in vegetables and fruits, and the nature of activated carbon. The ability to apply knowledge into specific problems. It not only exerts the guidance function of the correct emotional values ​​of students, but also reflects the application of chemistry; allows students to learn to use chemical knowledge to analyze and solve problems, reflect chemical value, and enhance children's scientific literacy to adapt to future development.

Innovate the situation proposition, examine the comprehensive ability

29 The introduction of "Shenzhou 14" as the situation, examining the material classification of aluminum alloy and the performance of the material of the material; 34 questions are the quality of related substances in the process of "electrolytic water". Knowledge background and dry material materials are novel, so that all candidates can answer the questions under the premise of understanding the material -free of test questions in the new knowledge context; the questioning method is clear, logical, and comprehensively examine students' applications that existing knowledge to solve problems flexibly solve the problem Capability, attention to the test of methods and thinking skills. The annual chemical finale question is the question of the 35th question. The "inquiry of the deterioration of sodium hydroxide" is organically combined with the degree of quality of the ion ingredient and material. The introduction of "related calculations" into the inquiry question is a change in this year's test questions this year's test questions. The focus is on examining the students' ability to integrate into the inquiry scene and carefully analyze and understand the experimental process. Establish children's scientific thinking and cultivate children's scientific methods for learning chemistry. The test questions fully respect the students' emotional experience and personality differences. The test questions focus on the experimental process, examine the inquiry ability, and the discipline characteristics are clear.

In the future chemical teaching and learning, we must always adhere to the goal of cultivating students' chemical disciplines, so as not to allow students to hardly memorize the concept, and we must not simply strengthen the training of exercises. We must pay attention to the cultivation of students 'thinking methods, inquiry spirit, and learning quality, so that students can develop the habit of self -learning, improve students' scientific inquiry ability, problem analysis ability, and language expression ability.
