Slide 19

Material models –

Reproduce geometric, physical and other properties of objects in material form Example: Globe (model of the globe) - geography

Slide 20

Information models –

Represent objects and processes in the form of diagrams, drawings, tables, formulas, texts, etc. Example: Drawing of a flower - botany, formula - mathematics

Slide 21

Slide 22

Classification of models by area of ​​use:

Training models; Experienced models; Scientific and technical models; Game models; Simulation models.

Slide 23

Classification of models taking into account the time factor:

Static; Dynamic. If the model takes into account changes in the properties of the modeled object over time, then the model is called dynamic, otherwise static. Examples: dynamic: wind-up toys; static: globe; soft toys; textbooks.

Slide 24

Classification of models by area of ​​use: Biological; Historical; Physical; Etc.

Slide 25

Modeling

Slide 26

Modeling as a method of cognition What a person’s attention is drawn to (object, phenomenon, process, relationship) for the purpose of studying is called an object. To study an object and solve a problem, it is necessary to build a model of a given object. A model is created by a person in the process of cognition of the surrounding world and reflects the essential features of the object, phenomenon or process being studied. Modeling is a method of cognition that consists of creating and studying models. Any model is not an absolute copy of its original; it only reflects some of its qualities and properties. The properties of the model depend on the purpose of the simulation. Models of the same object will be different if they are created for different purposes. Examples: periodic table, atomic structure model, model crystal lattice, skeleton model, dummies, models technical devices etc. Next Back

Slide 27

Classification of models Material models are material copies of modeling objects. Examples: globe, doll, robot, building models, dummies. Next Back Let's consider the most common characteristics by which models are classified: purpose of use (educational models, experimental, simulation, game, scientific and technical); field of knowledge (biological, economic, sociological, etc.) Method (form) of presentation Time factor According to the computer science textbook by N. Ugrinovich for grade 9

Slide 28

Information models Next Back Let's consider information models from the perspective of methods of presenting information: mental representation of an object (coding alphabet - a system of concepts, carrier - the human nervous system, brain); verbal presentation of the model using natural spoken language (form of presentation - oral or written message. Examples: instructions, literary works); figurative expression of the properties of the original with the help of images (drawings, films, geometric models) Figurative-sign Iconic Figurative-sign Structural models Drawings Plans Maps Graphs Tabular Network In the form of graphs Other Mathematical Logic Program texts Other

Binary matrices Maps, diagrams, drawings, graphs Quantitative characteristics and relationships between them General properties of models Modeling objects: - material objects; - natural phenomena; - processes Limitation of the model: - reflects only part of the properties of the modeling object Ambiguity of the model: - Various models one object, created for different purposes. Purpose of the model: - limited replacement of a real object; - using a model to predict the behavior of a real object According to the computer science textbook by I. Semakin for grade 9

Slide 30

Formalization Next Back What is formalization? This word is the essence of information modeling. The information model describes the modeling object in the form of any signs: letters, numbers, cartographic elements, mathematical or chemical formulas, etc. The most formalized science is mathematics. Formalization is the process of building information models using formal languages. Formalization is the result of a transition from the real properties of a modeling object to their formal designation in a certain sign system.

Simulation in spreadsheets

Slide 52

Many objects and processes can be described by mathematical formulas that relate their parameters. These formulas are the mathematical model of the original. Using them, you can make numerical calculations with different parameter values ​​and obtain quantitative characteristics of the model. Calculations, in turn, allow us to draw conclusions and generalize them. The spreadsheet processor provides a tool for calculating the quantitative characteristics of the object or process under study and takes on all the labor-intensive work of calculations. This topic highlights four main stages of modeling: problem statement, model development, computer experiment, analysis of simulation results.

Slide 53

MODELING SITUATIONS TASK Calculation of the number of rolls of wallpaper for pasting a room Stage I. Statement of the problem Description of the problem A store sells wallpaper. The names, length and width of the roll are known. Conduct a study that will automatically determine the required number of rolls for covering any room. The dimensions of the room are specified by the height (h), length (a) and width (b). Please note that 15% of the area of ​​the walls of the room is occupied by windows and doors, and when cutting, 10% of the area of ​​the roll is spent on scraps. The purpose of the modeling is to establish a connection between the geometric dimensions of a specific room and the selected wallpaper sample. Analysis of the object Modeling object is a system consisting of two more simple objects: rooms and wallpaper. Each of the objects included in the system has its own parameters. The connection between system objects is determined when setting the number of rolls for covering a room.

Slide 54

Stage II. Model development Information model

Slide 55

Mathematical model When calculating the actual area of ​​the roll that will be used for pasting the room, you need to discard 10% of the actual area for scraps. The calculation formula is: Sp=0.9*l*d, where l is the length of the roll, d is the width of the roll, * is the multiplication sign. When calculating the actual wall area, the non-glued area of ​​windows and doors is taken into account (15%) Scom = 0.85*2*(a+b)*h The number of rolls required for gluing a room is calculated by the formula where one spare roll is added.

Slide 56

Computer model For modeling, we will choose a spreadsheet environment. In this environment, information and mathematical models are combined into a table that contains three areas: initial data - controlled parameters (uncontrolled parameters are taken into account in the calculation formulas); intermediate calculations; results.

Slide 57

Task Fill out the calculation table according to the sample. Enter formulas into calculation cells.

Slide 58

Stage III. Computer experiment Modeling plan Carry out a test calculation of the computer model using the data given in the table. Calculate the number of rolls for the premises of your apartment. Change the data of some wallpaper samples and monitor the recalculation of the results. Add lines with samples and supplement the model with calculations using new samples. The results of the experiment are presented in the form of a report in a text editor. Modeling technology 1. Enter test data into the table and compare the results of the test calculation with the results given in the table. 2. Enter the dimensions of the rooms in your apartment one by one and copy the calculation results to text editor. 3. Write a report. Stage IV. Analysis of modeling results Using the table data, you can determine the number of rolls of each wallpaper sample for any room.

Stage I Statement of the problem. Stage I Statement of the problem. According to the nature of the formulation, all problems can be divided into three groups: The first group includes tasks in which it is necessary to study how the characteristics of an object will change under some influence on it: “what will happen if?..”. For example, will it be sweet if you put two teaspoons of sugar in tea? The second group of problems has the following formulation: what impact must be made on the object in order for its parameters to satisfy some given condition? This formulation of the problem is often called “how to do it so that...”. For example, what volume must a balloon filled with helium be in order for it to rise upward with a load of 100 kg? The third group is complex tasks. An example of such an integrated approach is solving the problem of obtaining a chemical solution of a given concentration. This stage characterized by two main points: description of the task; defining modeling goals; 3.

COMPUTER SIMULATION A.N. Petrova, teacher of special disciplines at Rzhev College

2 slide

Slide description:

Initially, the topic “Mathematical Modeling” was chosen by me when the computer base of the “Computer Science” subject consisted largely of the Qbasic programming language. With the advent of modern PCs, this topic naturally moved into the topic of “Computer Modeling.” The concept of computer modeling is closely related to such model names as: mathematical model; economic model; simulation model; interactive; computer experiment model; etc. And this is natural, since the computer and modeling are closely related to each other. In fact, every teacher, to one degree or another, engages in modeling.

3 slide

Slide description:

Omitting the theoretical calculations of the concept of models, we can give the following modeling scheme: The original object is a prototype, the original modeling is the process of creating a model, the modeled object is a substitute object

4 slide

Slide description:

The basis of varieties computer models serve such system concepts as image, sign, characteristics. modeled object (substitute object) Image Sign Characteristics Figurative models: dummies, models, photographs, drawings, drawings, etc., provided that there are no inscriptions or other signs on them Sign models: models based on artificial languages ​​(music signs, language of mathematical formulas - mathematical modeling, language of chemical formulas, etc.) Information models: models using a set of characteristics

5 slide

Slide description:

Depending on the behavior and state, models can be: Animated (computer animation); Imitative: imitating movement imitating the process of solving a problem using random numbers(Monte Carlo method) Interactive (models in which an interface is added - communication between the computer and the PC user).

6 slide

Slide description:

For the most part, we are dealing with mixed models. This, first of all, is connected with the purpose of modeling, which, in turn, determines one or another degree of formalization of the modeling object. For example: ...modeling graphic object– “CIRCLE” - Using the Fill tool, we get the “BALL” model

7 slide

Slide description:

The environment in which models “live” may be different. In this case, the model takes on a different variety. For example, the same models as Paint or Word objects (autoshapes), in the Qbasic environment, as programming objects, can be transformed from a simple animation model of a moving ball into a simulation-animation model of the structure of our solar system or a simulation-animation model of the structure atom or Brownian motion (depending on the purpose of the simulation). MODEL AS AN ENVIRONMENTAL OBJECT

8 slide

Slide description:

Having mastered the Qdasic DVIG.BAS algorithm for simulating the movement of graphic primitives, students continue to model with great interest, creating more and more complex simulation models. At the same time, there is an increase in interest in the programming language, in its deeper study: (organization of cycles with simultaneous reproduction of previous program designs. Changing parameters, selecting movement trajectories, the student actively works on numerous calculations. I will give examples of some works of the second year of studying programming (7 grades) cvetfr4.bas, cvetfr6.bas, skv318.bas

Slide 9

Slide description:

Students who became acquainted with the techniques of simulation-animation computer modeling in the lower grades continue to be interested in this topic in high school. There is an emerging interest in illustrative models that imitate the sound of a typewriter and use text functions ALEKS.bas, the first steps are being taken towards creating interactive models in dialogue mode PavelM1.bas

10 slide

Slide description:

For almost every computational problem on a particular topic, I try without fail, after setting the problem, before algorithmization, to move on to building a mathematical model of the problem, for example, on the topic “One-dimensional arrays. Search for mini-max. Fixing the index” Mathematical model of the problem “SEARCHING MIN/MAX IN A ONE-DIMENSIONAL ARRAY” n – number of elements in array A A(i) – element of array A(i) i=1,n; A(i) = RND*100 MIN - minimum element of array A; IMIN - index (position) of the minimum element in array A; MAX - maximum element of array A; IMAX - index (position) of the maximum element in array A; A(1), initially MIN = A(i), if A(i)< MIN, для i=1,n; 1, первоначально IMIN = i, если A(i) < MIN, для i=1,n; A(1), первоначально MAX = A(i), если A(i) >MAX, for i=1,n; 1, initially IMAX = i, if A(i) > MAX, for i=1,n;

11 slide

Slide description:

On topics related to two-dimensional arrays, in addition to the usual mathematical models of problems, students, under my guidance, create interactive and animated demo versions of problems such as “CARRIAGE CAR”, “Storage Luggage”, models that are different from standard information models (characteristics of the type Value, Name), with the addition of a description of behavior and interface, become the above-mentioned models (KAMBAG.bas, VAGVAG.bas). On the same topics: interactive models “Solving a system of linear equations using a matrix method (Gauss method)”, “Identification of material by Young’s modulus”).

12 slide

Slide description:

The topic “Generating random numbers” is well illustrated by solving problems: “Calculating the number π” and “Calculating the area of ​​an arbitrary figure” with the creation of a simulation model of the solution.

Slide 13

Slide description:

For this task, students can complete a competitive work on modeling a simulation model of a graphical mini-editor to create an arbitrary figure, the area of ​​which must be determined. LITKIN On the topic “Sound and Graphics”, a large number of animation models were created under my leadership. These developments were demonstrated at one of the open lessons. There was a non-standard lesson “Conference of Young Professionals”. The mathematical model “Method of approximate extraction of roots” was submitted to the city scientific and practical conference (3rd place). Good results are obtained when modeling in the PowerPoimt environment: intensification of the study of working with objects in this environment; improving the skills of formalizing the model. link Nadya While getting acquainted with the Paint graphic editor, a student can become familiar with the construction of a complex model, composing, for example, a complex drawing with repeating primary simple objects (cutting, copying, rotating...).

Slide description:

The lessons on modeling page fragments with built-in animation objects turn out to be interesting. For example, after an integrated school lesson in 9th grade “Introduction to the electronic encyclopedia of astronomy,” students learned how to model various pages: “What do we know about the Moon?”; “Planets of the solar system and their satellites”; “Planets in numbers” Mass; Diameter; Surface temperature; Duration of sidereal day; Orbital period. “Comets”; Etc.

Slide 17

Slide description:

Modeling the page “What do we know about the Moon?” (in PowerPoint environment) The Earth's shadow near the Moon has a larger angular size than that of the Moon, so the Moon's crossing of this shadow can last tens of minutes. First, the Moon on the left is touched by the barely visible penumbra of the Earth (for an observer on the Moon standing in the penumbra, the Sun is partially blocked by the Earth). The Moon's crossing of the penumbra lasts about an hour, after which the Moon is touched by a shadow (for the same observer on the Moon, in the shadow, the Sun is completely blocked by the Earth).

Modeling in Excel environment Electronic environment Excel tables – perfect tool for mathematical modeling, as it quickly and masterfully performs labor-intensive work on calculating and recalculating the quantitative characteristics of the object or process under study. Modeling in spreadsheets is carried out according to a general scheme, which distinguishes four main stages: problem formulation, model development, computer experiment and analysis of results. For example, the task “Solving linear equations using the method inverse matrix” Statement of the problem: Solving a system of linear equations using the specified method Modeling – selection of the necessary formulas for solving the problem using the inverse matrix method and algorithmization of the problem (formalization of the problem). Computer experiment – ​​testing a problem with various initial data. Analysis of the results obtained - has a solution been found that satisfies the conditions of the problem?

Slide 19

Slide description:

This task, according to the classification of Professor A. N. Makarova, can be classified as a task that has the following generalized formulation: what effect must be exerted on the object so that its parameters satisfy some given condition. This group of tasks is often called “how to do so that...”. This group of tasks included such tasks that I had already tested at Excel computer workshops in previous years of study, such as “Solving a system of linear equations with the Search for Solutions tool”, “Modeling the recognition of a situation where a point hits a X,Y coordinates to a specified area using the method conditional formatting and constructing a diagram”, “Modeling objects (house, chess) in Excel using cell formatting and a simple macro”, “Solving systems of nonlinear equations using the Search for Solutions method”, “Modeling the recognition of intervals of a function in which the function is not defined”

Hypertext modeling Hypertext (non-linear text) is an organization of text information in which the text is a set of fragments with explicitly indicated associative connections between these fragments. The associative connection between fragments is called a hyperlink, which can be written explicitly using a special hypertext markup language HTML documents(Hyper Text Markup language) or by declaring a hyperlink in a particular application (PowerPoint, Word) One of the promising areas for the development of hypertext systems is hypermedia technology - a combination of hypertext technology and multimedia technology (integration of text, graphics, sound, video). Examples of the development of hypermedia applications are various electronic publications - reference books, encyclopedias, training programs.

TARGETED MODELING Research work on computer modeling carried out with a particular student (or group) involves guidance, assistance and control over a complex set of preliminary works related to target computer modeling: Analysis of the problem statement, description of the problem Development of a clear main goal of the modeling; Formalization of the task and, as a consequence, development of clear intermediate goals. Often the goals (main and intermediate) are to answer clarifying questions in accordance with the statement of the problem; Analysis and study of various possible modeling environments, comparing their advantages and disadvantages in order to make a final decision on the choice of modeling environment; Computer modeling with repeated testing of the model Choosing a method for presenting the model

Slide description:

Target modeling, depending on the set and intermediate goals, the novelty of the material and its volume, can be very long in terms of execution time. For example, computer simulation of the educational electronic manual “Working in an environment standard application Windows Paint”, made by student Vladimir Mashkovtsev (11th grade 2003/2004) and submitted to the city practical conference in 2004. (3rd place) lasted one year and included the following set of works:

Slide 27

Slide description:

Stage I. Statement of the problem (formal): Development of an electronic manual for working in the environment of the graphic editor Paint. The first basic requirement: simplicity and ease of use of the electronic manual. Formalization of the task: The modeling prototype must meet modern requirements for the development of an electronic manual - it must be based on the use of hyperlinks, have either a standard Web design or its own (unique), have the property of interactivity. The user must be able to simultaneously use the electronic manual and the Paint graphic editor (type of manual “ Read  Done”). The interface of the manual must meet the requirements of transition to any structural part of the manual and return to the starting point; Transition and return points must carry a clear, unambiguous load. Stage II. Modeling in accordance with the formalization of the problem in the hypertext markup language HTML Stage III. Multiple computer experiment (model debugging) Stage IV. Analysis of results. “Running in” of the electronic manual in basic and elective computer science lessons (the Manual has received universal recognition).

The duration of work on the video project was two academic years. The work was twice submitted to the city scientific and practical conference (2003/2004 academic year - 3rd place; 2004/2005 academic year - 1st place). The interactive video project was timed to coincide with the anniversary (400 years) of the Nilo Stolobenskaya Hermitage Monastery, was called “Island of Spiritual Consolation” and was demonstrated at school lessons on Orthodox Culture

Slide 33

Slide description:

Brief conclusions: Computer and modeling are closely related to each other. The basis of the varieties of computer models are such system concepts as image, sign, characteristics. Depending on the behavior and state, models can be animated (computer animation), simulation (simulating movement, simulating a real computing process, replacing it with a process based on pseudo-random numbers (Monte Carlo method), interactive (models in which an interface is added - connection between the computer and the PC user). The environment in which the models “live” can be different. In this case, the model also takes on a different variety - this is a very fertile ground, because it opens up the enormous creative potential of children. there are sparks of computer creativity in them, one might expect good results children in the future (Vova Fedorov, Alyosha Semenov, Igor Ogarev, Sasha Katkov, Anya Yudashkina, Yura Nikitin, Roman Suvorov, Pavel Alekseev, Volodya Mashkovsky, Seryozha Polozov, Sasha Korolevsky, Nadya Sysolyatina, Seryozha Mikhailov, etc.). Computer modeling can, in addition, be considered as a powerful tool for motivating learning and self-learning in the subject of Computer Science, as it encourages students to independently search for deeper knowledge in this area and apply it in practice in the process of numerous computer experiments. As a result, repeated prizes at city Olympiads in computer science and city scientific and practical conferences.
