models?
2. Discussion of the results of the tasks number 1-4 in the textbook:
1) Answer: The speed of sound distribution on the winter day at a temperature - 35 0 From equal to 310 m / s, and on a summer day - at a temperature of + 30 0 C is 352 m / s.
2a) Answer: The number of days is calculated by the formula :.
2B) Answer: The time through which cyclists will meet are calculated by the formula: minutes.
3) Answer: time is calculated on the basis of the formula. As t. = 8 hours B. \u003d 24 hours, then \u003d \u003d 12 hours.
4) Answer: Wires are definitely enough to mark the flower beds d) and not enough for the option b). When solving options a) and c), it is necessary to mentally "break down the steps" and make sure that in each of these cases it turns out a rectangle 6 * 10, and, consequently, the wires are sufficient.
2) Explanation of the new material: Table information models.§ 2.5.1.
(Accompanied by a presentation show 7_2.5.1_ tabular information models ")
The explanation of the new material is organized in the form of a conversation supported by the demonstration of the presentation "Table Information Models" (slides 2- 4). It is desirable to use the existing experience of schoolchildren to use table information models as much as possible. It is important to summarize the students to the conclusion that the information presented in the table is visual, compact and easily promined.
Pupils should consider drawings and specify objects and identical properties of objects (slide 5). The figures depicts girls in national costumes (Spanish, Russian, Indian). Each suit has a dress, a headdress and musical instruments.
Make a table "National costumes" (slide 6.)
Emphasize that the information in the table is visual, compact, easy to see.
Create examples of tabular information models (tables), in which information is visual, compact, easy to see. (Slide 7).
Special attention should be paid to the rules for designing tables. In the future, it is necessary to strictly follow these rules. (Slide 9-11).
It should be noted that all many tables can be divided into simple and complex.
3) Fizkultminutka.
It is known that children are quickly tired in the lessons, because long time is in a static position.
Fizkultminthki helps the prevention and removal of mental fatigue.
Conduct physkultminutka by 12-20 minutes from the beginning of the lesson.
Duration 1-2 minutes.
(An electronic physical attack is carried out for the eyes.)
4) Practical work.
The practical part of the lesson (tasks number 1 and No. 2 of work No. 6 "Creating tabular models") is devoted to the formation of the skills of creating and formatting tables.
When executing a task number 1, "Giant" It is important to ensure that the students do not create five different tables, and edited the first table using the insertion and removal of strings and columns using autoformatting and implementing data sorting.
In the task number 2, the Nature of Russia, students not only work out technological reception (cell combining), but also produce selection necessary to fill out a table of information from a text document.
5) homework
§ 2.5 (p. 58-60); Answers to Questions Nos. 1 - 6 (p. 69)
6) Reflection
Each student has on the table card (green, yellow, red). Leaving the class, you need to leave one of them on the teacher's table:
Green "I am satisfied with a lesson, a lesson was useful for me, I have a lot, with benefit worked at the lesson received a well-deserved assessment, I understood everything about what was stated in the lesson.
Yellow - The lesson was interesting, I took an active part in it, the lesson was at a certain extent useful for me, I answered from the place, I managed to fulfill a number of tasks, I was at the lesson quite comfortable.
Red - I received a little use from the lesson, I didn't really understand what it was about, I don't really need it, I will not fulfill my homework, I was not ready to answer the answers in the lesson.

I.. Discussion of the performance of homework (because not all do it). The praise of individual students for activity in the previous lesson.
II. . Today you were asked to come up with the example of educational, scientific and technical, experienced, game and imitation models. Who coped with this task? (I check the presence of D.R., I ask you to read the most successful examples)
III. And now check how you learned the material of the previous lesson. Close, please, all notebooks and textbooks. I will give you a test. It gives 3 minutes. For each question you need to choose one correct answer. Started.
(See Test 3)
IV . And now proceed to the study of a new material. We write down the topic of today's Table Information Models lesson.
Guys, you have already met with the classification of models according to the presentation method. What two large groups share models?
- Material and informational.
(2 slide)
Let's remember what information model is?
- Information model - This is a combination of information that characterizes the properties, the state of the object and the relationship with the outside world.
Thus, the information model is a set of information. In turn, this set of information can be represented in different form. What do you think in what form it can be represented?
(3 slide all that is on the slide is recorded)
First, she M.B. Presented in graphical form, for example, in the form of a scheme, graphics, drawing, cards.
Secondly, in verbal form. What do you think is a verbal form?
Verbal shape.
That's right, the verbal form is a verbal description.
The third form is mathematical. This description of relations between the quantitative characteristics of the object on the mathematical language. For example, a triangle area formula.
And the last form, what do you think, what? This is a tabular form. It is in this form that we will stop more in detail.
Well, we got acquainted with you with four forms of the information model. But then there is such a question: what form to choose when creating a model? And the answer is actually very simple.
(4 slide, write)
The form of the information model depends on the purpose of its creation.
Let's look at this on the example.
(5 Slide orally)
We are faced with the goal to trace the temperature change in June 2006. What information do we possess? We have a temperature for every day of June. What do you think, in what form can we submit this information?
In graphical form.
Correctly we can imagine it in graphical form in the form of a graph.
(5 slide)
What can we see on this schedule?
Where the temperature grew, and where he dropped.
What day was the maximum temperature and what is it equal to?
What day was the minimum temperature and what is it equal to?
(Answer, but what day cannot say for sure.)
Thus, we see that the schedule gives us clarity, but the accuracy of the PI is lost.
Can we submit this information in any other form?
It is possible in the form of a table.
What is the convenience of this form of presentation?
The data is more accurate.
But then we will lose clarity. Well, let's consider another example.
(6 Slide orally)
We need to study which seas and oceans are washed by mainland Australia. What form of information model we are most convenient to choose.
Graphic shape, namely the card.
Is it possible anyhow somehow? Of course you can, for example, verbally. From the West Australia is washes the Indian Ocean, from the east of Tasmanovo Sea, etc. We can list all words, but will it be convenient for us to study geography thus? Not. We will not be clear.
Thus, we see that the graphic form is selected if an important requirement is visibility.
Now consider the following example. We need to explore estimates of three students for the first quarter. In what form can we submit this information model?
In graphical form in the form of a graph.
Well, look at the schedule built by me.
(7 Slide orally)
Is it convenient to study academic performance on it? And if there are a lot of students, all the graphs are confused, and it will be even more not more convenient.
How else can this information model be present?
In the form of a table.
This form is most convenient in this case, since the information is written more compact, systematized.
Thus, we see that the tabular form is selected if we need to systematize information.
Today at the lesson we will get acquainted with the tabular form of the information model. We will discuss from what the table consists of what it is characterized by what types of tables are.
As an example, consider the table. This is a testing table. This table includes estimates of three students in four subjects.
(8 Slide orally)
How many lines in this table? Name the names of the lines.
How many columns in this table? Name the names of the columns.
At the intersection of rows and columns are cells. What is listed in the cells? Thus, we can say that each table is characterized by:
the title (and if there are several tables, then another number)
the number of lines and their names (string headers)
the number of columns and their names (column headers)
content cells located at the intersection of columns and lines.
Once again inspect the table. It contains a combination of information about objects, that is, we can call this table with the information model of the academic process.
And now you will learn what types of tables exist.
(9 Slide write all that is on the slide)
The first type is the Table Object-property, the second type - the object object object and the third type - combined tables. What is this table? (Switch by reference).We write a definition:
Table object-property- This is a table in which several properties are reflected, and all objects belong to one set.
Consider an example of such a table. Table "Data on students". This table reflects four properties: date of birth, growth, etc. All objects belong to one set - a variety of students. Leave after defining the place, at home you will give your example of the Table object-property.
And now consider the Type Table Type object. We write a definition:
Table object object - This is a table that reflects one property characterizing two or more objects.
Consider an example of such a table. Table "Football Games". In this table, one property (date of the game) characterizes three objects (three classes). Leave after defining the place, at home you will give your example object object.
(next slide)
What type of table is this table? As you have already noticed in this table, several properties that characterize three objects, i.e. The table consists of two tables. Such a table is called combined. We write a definition:
Combined Table - This is a table obtained by combining in one table of several tables of the form "O.-O." and "O.-S.". Leave after defining a place, at home you will give your example of a combined table.
(next slide)
What type of table is the following table?
Object object.
Please look at the contents of its cells. The cells contain numbers. So now the rectangular table, composed of numbers, is called a matrix. We write this definition.
You probably have already noticed that the table consists of zeros and units. This table is called a binary matrix. We write this definition:
Binary matrix - This is a matrix made up of zeros and units.
It reflects the qualitative nature of the relationship between objects.
At home, come up with your example of the matrix and binary matrix.
V.. So guys, what's new you learned today at the lesson?
What is a matrix, binary matrix, what are the types of tables, how to choose the form of information model.
Are there any questions about the new material?

What is the model? The model is a simplified similarity of a real object. The model reflects only some object properties substantial in terms of modeling target. What is modeling? Modeling is a person's activities for creating a model (invention or informational). The concept of modeling should be understood in the broadest sense. It may be material object: Ship, Comet, Live Cage; natural phenomenon: thunderstorm, solar eclipse; process: Flying rockets, changing the value of shares on the stock exchange and much more. Give the definition of formalization. Formalization is the result of the transition from the real properties of the modeling object to their formal Designation in a specific iconic system. 1) What is the simplified representation of the real object?
- original;
- prototype;
- model;
- system.
2) The process of building models is called:
- modeling;
- constructing;
- experimentation;
- design.
When do modeling use?
3) The information model consisting of rows and columns is called:
- schedule;
- scheme;
- drawing;
- table.
In addition to information,
what are the models in nature?
4) What is the general name of models that are a totality of useful and necessary information about the object?- material;
- information;
- subject;
- verbal;
- layout;
- definition;
- drawing;
- A + V + C \u003d 180 °, AU2 \u003d AC2 + SU2.

Graphic Information Models (Scheme, Structure, Graph) The scheme is a graphical display of the composition and structure of a complex system. The structure is the order of combining the elements of the system into a single whole. The schedule is a process model.These are drawings, photos, schemes, diagrams, and so on. They help us quickly and understand the information to the listener.

The most important thing
Tables are used to describe a number.objects possessing the same
set properties.
The table consists of columns and lines.
The information presented in the table
Visual, compact, easy to see.
Table type "Object properties"
contains information about properties
individual objects belonging
one class.
The most important thing
Table type "object objects-one"contains information about some one
Property of pair of objects, most often
belonging to different classes.
Computationally called tables, where
The values \u200b\u200bof some properties are calculated
using the values \u200b\u200bof other properties
