Lesson topic: Modeling is a method of cognition. Model presentation form.

The purpose of the lesson: To acquaint students with various models found in the world around them and consolidate the knowledge gained.

Lesson objectives:        

1. Educational: to form the concept of modeling as a method of cognition; consider different classifications of models; to form the concept of "information model", to learn how to describe information models.

2. Developing: work on the development of logical thinking, mindfulness, activity; contribute to broadening one's horizons.

3. Educational: education of organization, concentration, responsibility, information culture.

Means of education:: textbook Ugrinovich N.D. Computer science and information technology. Textbook for grades 10-11, cards with the task.

Lesson structure:

1.     Organizational moment (2 minutes);

2.     Learning new material (22 minutes);

3.     Playing a game (10 minutes);

4.     Summing up, student questions, homework assignment (6 minutes)

 

During the classes

Good afternoon, guys, have a seat. Who is absent today? (mark those present).

Humanity in its activities (scientific, educational, technological, artistic) constantly creates and uses models of the surrounding world. Models make it possible to visualize objects and processes that are inaccessible for direct perception (very large or very small objects).

The topic of today's lesson is “Modeling as a method of cognition. Model submission forms "

A soft toy, a globe, a model of a building, an internal combustion engine, DNA models, a mathematical formula - these are all models. How can such different concepts be called in one word?

Model- this is a new object that reflects the essential features of the studied object, phenomenon or process.

Models play an important role in the creation of various technical devices, machines and mechanisms, buildings, electrical circuits, etc.

The development of science is impossible without the creation of theoretical models - theories, laws, hypotheses, etc.

All artistic creation is a process of creating models: any literary work is a model of real human life, paintings, sculptures, theatrical performances.

No model can replace the object itself. But when solving a specific problem, when we are interested in certain properties of the object under study, the model turns out to be a useful, and sometimes the only research tool.

Modeling is a cognitive method of creating and exploring models.

We have made sure that there can be a huge number of models. And in order to navigate in their diversity, it is necessary to classify all this, i.e. to order, systematize in any way. Let's take a look at the classification of models by way of presentation

1.     Material - They reproduce the geometric and physical properties of the object and always have a real embodiment. (for example: Children's toys, stuffed birds, maps, diagrams, models, experiments, etc.)

2.     Informational - a set of information that characterizes the properties and states of an object, process, phenomenon, as well as the relationship with the outside world, i.e. any description of an object in one of the spoken or formal languages

2.1. Verbal - informational model in mental or spoken form. (for example, Mental image of an object: Model of human behavior when crossing the street; A musical theme that flashed through the composer's head is a model of a future musical work.)

2.2. Signed - an information model expressed by means of a formal language. (for example, pictures, texts, graphics, diagrams, etc.)

2.2.1.   Computer - a model implemented by means of a software environment. (for example, electronic versions of drawings, drawings, texts, formulas and their creation using various software)

2.2.2.   Non-computer - a model created using traditional tools of an engineer, artist, writer, etc. (for example, drawings, drawings, graphics, etc.)

Next, consider the classification of information models in the form of presentation.

1. Verbal models - oral and written descriptions using illustrations.

2. Mathematical models - mathematical formulas that reflect the relationship between various parameters of an object or process.

3. Graphic - the simplest type of model that conveys the external features of the object.

Now, we will consolidate the acquired knowledge in practice. Your task is to solve the Hungarian crossword puzzle. The Hungarian crossword puzzle is a field of cells in which the letters of the answers are already inscribed. In the chain of cells that make up each answer, adjacent cells must be in contact. Answer words do not overlap and do not have cells in common with other words. Cross out words related to material models with a pencil, words related to information models with a pen. You have 10 minutes to complete the task. Whoever copes with the task faster and more correctly will receive a positive mark. Time has passed (cards with the task are handed out to the children).

Time is over. Guys, exchange cards, now together we will check the correctness of your answers.

Answers:

Material models: calculator, pillow, greenhouse, globe, machine, skeleton, ruler, toy, pattern, building, frame, table, computer, well, robot, ladder, wig, statue, sculpture, pendant, stuffed animal, train, plane, ship , doll, vase.

Come to me with the diaries guys who found 50-60 correct words.

Currently, computer modeling in scientific and practical research is one of the main elements of cognition. Modeling skills are also very important for a person in his daily activities. They help to reasonably plan the daily routine, study, work, choose the best options if you have a choice, successfully solve various life problems.

Write down the homework assignment. Study the paragraph of the textbook on the topic “Modeling as a method of cognition. Model presentation form ".

The lesson is over. Everybody's Free.
