Psychological and pedagogical characteristics of the team of 7th grade
The work program is drawn up taking into account the individual characteristics of students in the 7th grade and the specifics of the class team. There are 25 students in the class, of which 14 are boys and 11 are girls. A distinctive age-related feature of children is the increased interest in each other on the part of boys and girls, which should also be taken into account when organizing work in groups of permanent and shift composition and when seating children in a classroom.
There are fairly even, generally friendly relations between students. above baseline
Psychological and pedagogical characteristics of the team 7 b class
The work program is compiled taking into account the individual characteristics of students in grade 7b and the specifics of the class team. There are 25 children in the class, of which 17 are boys, and 8 are girls. class.
There are fairly even, generally conflict-free relations between students. There is a group of children who are distinguished by an extremely slow pace of activity, are hardly involved in collective (group or pair) work, are embarrassed to give answers orally, and do not differ in competent monologue speech. In working with these children, an individual approach will be applied both in the selection of educational content, adapting it to the intellectual characteristics of children, and in the choice of forms and methods of its development.
The bulk of the students in the class are children with a sufficiently high level of abilities and motivation for learning, who are able to master the program in the subject above baseline. They are distinguished by sufficient organization, discipline, responsible attitude to the implementation of educational, especially homework assignments.
With this in mind, the content of the lessons includes material of an increased level of complexity, differentiated tasks are offered both at the stage of working out ZUNs and at the stage of control. The organization of work with this group of students also takes into account the fact that they do not differ in a high level of independence in educational activities and are more successful in working according to the model than in performing tasks of a creative nature. These guys are often unsure of themselves, suspicious, afraid of making mistakes and have difficulty experiencing their own failures. In order to correct and level these features, the children will study individual topics on their own using individual educational programs (IEP).
Psychological and pedagogical characteristics of the team 7 in the class
The work program is compiled taking into account the individual characteristics of students in the 7th grade and the specifics of the class team. There are 16 students in the class, of which 5 are boys and 11 are girls. A distinctive age-related feature of children is the increased interest in each other on the part of boys and girls, which should also be taken into account when organizing work in groups of permanent and shift composition and when seating children in a classroom.
There are fairly even, generally conflict-free relations between students, but there is a child who stands out from the class team. In working with this child, an individual approach should be used both in the selection of educational content, adapting it to the intellectual characteristics of the child, and in the choice of forms and methods of its development, which should correspond to personal characteristics.
The bulk of the students in the class are children with a very average level of ability and low motivation for learning (most children come to school to communicate), who find it difficult master the program in the subject even at a basic level. They are characterized by poor organization, lack of discipline, often irresponsible attitude to the performance of educational, especially homework assignments. They have insufficiently formed basic mental functions (analysis, comparison, highlighting the main thing), poor memory.
In the class, one can single out a group of students who quite often do not have everything they need for the lesson, do not do their homework. In order to include these children in the work at the lesson, non-traditional forms of organizing their activities, frequent changes in the types of work will be used, because these children are not able to force themselves to work by force of will.
In general, students in the class are very heterogeneous in terms of their individual characteristics: memory, attention, imagination, thinking, level of performance, pace of activity, temperament. This necessitated the use in working with them of different channels of perception of educational material, various forms and methods of work.
Forms and means of control.
The main methods for testing students' knowledge and skills in physics are oral questioning, written and laboratory work. Written forms of control include: physical dictations, independent and control work, tests. The main types of knowledge testing are current and final. The current check is carried out systematically from lesson to lesson, and the final check is carried out at the end of the topic (section), school course.

General characteristics of the study of physics in grade 7:
Physics as a science of the most general laws of nature, acting as a school subject, makes a significant contribution to the system of knowledge about the world around us. It reveals the role of science in the economic and cultural development of society, contributes to the formation of a modern scientific worldview. To solve the problems of forming the foundations of a scientific worldview, developing the intellectual abilities and cognitive interests of schoolchildren in the process of studying physics, the main attention should be paid not to transferring the amount of ready-made knowledge, but to getting acquainted with the methods of scientific knowledge of the world around us, posing problems that require students to work independently to resolve them.
The 7th grade physics course includes the following sections:
Initial information about the structure of matter
Interaction of bodies
Pressure of solids, liquids and gases
work, power, energy
Goals studying physics in grade 7:
learning about mechanical, thermal, electromagnetic and quantum phenomena; quantities characterizing these phenomena; the laws to which they are subject; methods of scientific knowledge of nature and the formation on this basis of ideas about the physical picture of the world;
mastery of skills conduct observations of natural phenomena, describe and generalize the results of observations, use simple measuring instruments to study physical phenomena; present the results of observations or measurements using tables, graphs and identify empirical dependencies on this basis; apply the acquired knowledge to explain various natural phenomena and processes, the principles of operation of the most important technical devices, to solve physical problems;
