Free lesson description:

  • The lesson is the final lesson in studying the topic “Text Information Processing”.
  • Students develop a two-page booklet (leaflet) about the school and its school grounds or about a nearby residential building and its yard.
  • This is practical work carried out on site. To complete this work, students are divided into two groups, each of which does its part of the work.
  • The described territory must contain a sufficient number of objects that could be divided into 2 different categories (according to the number of groups). For example, the description of school (home) and infrastructure is one category that is described by one group. The second category of objects are objects available in the schoolyard (in the courtyard of the house): children's and sports grounds, small architectural forms, etc., which is described by the second group.
  • The booklet (leaflet) should include the structural elements of a text editor (processor) that were studied in class.
  • The composition of the structural elements is determined by the teacher based on the material covered. A list of them is given to students as a mandatory element of practical work.

1.Organizational stage.

Creating a favorable climate in the classroom.

I greet the students, check their readiness for the lesson, and organize the children’s attention.

The teachers greet, check the availability of educational material on the tables, and organize their workplace.

Communicative: planning educational collaboration with peers.

Personal: psychological readiness of students for the lesson, self-determination.

2. Updating knowledge.

Updating basic knowledge and methods of action. Formulating the topic and purpose of the lesson.

In previous lessons, we got acquainted with two types of formatting: style and direct. I asked you to take home everything related to formatting. Let's start with what is formatting anyway?Children's answer: the process of its registration. What two formatting methods are there?Children's answer: direct and stylish. What is direct formatting used for and its peculiarity?Children's answer: apply to arbitrary character fragments (symbols, words, lines, sentences) and paragraphs. What is style formatting used for and its features?Children's answer: apply to large texts. What is the advantage of style formatting over straight formatting?Children's answer: saves time, ensures uniformity in design, and so on. What is the orientation of a sheet of paper?Children's answer: book, landscape. What a great fellow you are! It is clear that they have been taught.

Today in class we are starting a new topic, but tell me which one you yourself, and some of the images that you see on the slide will help you with this. And here is my guiding question: what information does a person perceive better? That is, what information is easier for us to perceive? Which one will contain what? Answer: which contains lists, diagrams, pictures. What is the name of such information that contains lists, pictures, diagrams, tables? The name of such information was derived from the word “eyes”. Children's answer: visualized information. So what is the topic of the lesson? Children's answer: “Visualization of information in text documents.”

That’s right, open our notebooks, write down today’s date, class work and the topic of the lesson “Visualization of information in text documents”(T, D).

Answer questions about homework.

Formulate the topic of the lesson.

Operating principle. UUD: regulatory (problematic presentation of educational material).

3. Presentation of new material.

It is known that text information is perceived better by a person if it is visualized - organized in the form of lists, tables, diagrams, and provided with illustrations (photos, drawings, diagrams). Modern word processors provide users with ample opportunities to visualize information in the documents they create. Let's look at it firstlists . Write down a subtitle for yourself - “Lists”(T, D).

All kinds of lists in documents are drawn up using lists. In this case, all items on the list are considered as paragraphs, formatted according to a single template. According to the method of design they distinguishnumbered Andmarked lists.

Elements of a numbered list are identified by sequential numbers, which can be written in Arabic or Roman numerals. List elements can be numbered and letters - Russian or Latin. A numbered list is usually used in cases where the order of the items is important. Such lists are especially often used to describe a sequence of actions. You regularly create numbered lists by filling out a lesson schedule for each day in your diary.

When you create new, delete, or move existing numbered list items in a word processor, the entire list numbering changes automatically.

Fig.1. Example of a numbered list

Elementslabeled list are indicated using markers. The user can select any symbol of the computer alphabet, and even a small graphic image, as a marker. Use a bulleted list to list keywords at the beginning of each paragraph in your textbook.


Fig.2. Bulleted list example

A bulleted list is used in cases where the order of the elements in it is not important. For example, in the form of a bulleted list, you can draw up a list of subjects you studied in 7th grade.

According to the structure they distinguishsingle-level Andmulti-level lists. The lists in the examples discussed above have a single-level structure. A list whose element is itself a list is called multi-level. So the table of contents of your computer science textbook is a multi-level list. Lists are created in a word processor using a menu bar command or formatting bar buttons.

Write down the following subheading – “Tables”(T, D).

To describe a number of objects that have the same sets of properties, tables consisting of columns (graphs) and rows are most often used. You are well aware of the tabular presentation of the lesson schedule; the schedule of buses, planes, trains, and so on is presented in tabular form.

The information presented in the table is clear, compact and easy to see. The table can contain not only symbols and text, but also some graphic images. Example on the board.

You can create a table using the corresponding menu item or button on the toolbar, specifying the required number of columns and rows; In some word processors, the table can be "drawn". The created table can be edited by changing the column width and row height, adding and deleting columns and rows, merging and splitting cells. You can enter information into the table like this: using the keyboard, copy and paste pre-prepared fragments.

You can design the appearance of the table yourself by selecting the type, width and color of the cell borders, the background color of the cells, and formatting the contents of the cells.

As I already said, a table can contain not only text, but also a graphic image. Ready-made graphic images can be edited by changing their size, primary colors, brightness and contrast, rotating, and so on.

Many word processors have the ability to directly create graphics from autoshape sets. It is also possible to create colorful inscriptions using built-in text effects. You can visualize the numerical information contained in a table using diagrams, tools that are also included in word processors.

This is all the theory you need to visualize information. Your questions, what do you not understand? Maybe something else needs to be repeated? The teacher answers the children's questions.

Now I invite you to do practical work, the purpose of which is to learn how to build tables and apply numbered and bulleted lists to text.

The teacher listens carefully and takes notes on important points.

Discuss the table.

Cognitive:

extracting the necessary information from what the teacher said.

Regulatory:

It is known that text information is perceived better by a person if it is visualized - organized in the form of lists, tables, diagrams, and provided with illustrations (photos, drawings, diagrams). Modern word processors provide users with ample opportunities for visualizing information in the documents they create.

4.4.1. Lists

All kinds of lists in documents are drawn up using lists. In this case, all items on the list are considered as paragraphs, formatted according to a single template.

Based on the design method, a distinction is made between numbered and bulleted lists.

Elements (items) of a numbered list are designated using sequential numbers, which can be written in Arabic and Roman numerals. List elements can also be numbered with letters - Russian or Latin (Fig. 4.14).

Rice. 4.14.
Examples of numbered lists

A numbered list is usually used in cases where the order of the items is important. Such lists are especially often used to describe a sequence of actions. You regularly create numbered lists by filling out a lesson schedule for each school day in your diary.

When you create new, delete, or move existing numbered list items in a word processor, the entire list numbering changes automatically.

Items in a bulleted list are indicated by bullet icons. The user can select any symbol of the computer alphabet, and even a small graphic image, as a marker (Fig. 4.15). Use a bulleted list to list keywords at the beginning of each paragraph in your textbook.

Rice. 4.15.
Examples of bulleted lists

A bulleted list is used in cases where the order of the elements in it is not important. For example, in the form of a bulleted list, you can draw up a list of subjects you studied in 8th grade.

The structure distinguishes between single-level and multi-level lists.

The lists in the examples discussed above have a single-level structure.

A list whose element is itself a list is called multi-level. Thus, the table of contents of your computer science textbook is a multi-level (three-level) list.

Lists are created in a word processor using the menu bar command or formatting bar buttons (Figure 4.16).

4.4.2. Tables

To describe a number of objects that have the same sets of properties, tables consisting of columns (graphs) and rows are most often used. You are well aware of the tabular presentation of the lesson schedule; the schedules of buses, planes, trains and much more are presented in tabular form.

The information presented in the table is clear, compact and easy to see.

A correctly designed table has the structure shown in Fig. 4.17.

Rice. 4.17.
Table structure

The following rules for formatting tables must be observed:

  1. The title of the table should give an idea of ​​the information contained in it.
  2. Column and row headings should be short, not contain unnecessary words and, if possible, abbreviations.
  3. The table must indicate the units of measurement. If they are common to the entire table, then they are indicated in the table title (either in parentheses or separated by a comma after the title). If the units of measurement differ, they are indicated in the heading of the corresponding row or column.
  4. It is advisable that all table cells be filled in. If necessary, the following symbols are entered in them:

      Data unknown;

      x - data is impossible;

      ↓ - data must be taken from the overlying cell.

Texts, numbers, and images can be placed in table cells. An example of a table is shown in Fig. 4.18.

Rice. 4.18.
Example table

You can create a table using the corresponding menu item or button on the toolbar, specifying the required number of columns and rows; In some word processors, the table can be "drawn". The created table can be edited by changing the column width and row height, adding and deleting columns and rows, merging and splitting cells. You can enter information into cells like this: using the keyboard; copy and paste pre-prepared fragments. Word processors have the ability to automatically convert existing text into a table.

You can design the appearance of the table yourself by selecting the type, width and color of the cell borders, the background color of the cells, and formatting the contents of the cells. In addition, you can format the table automatically.

4.4.3. Graphic images

Modern word processors allow you to include in documents various graphic images created by the user in other programs or found on the Internet. Ready-made graphic images can be edited by changing their size, primary colors, brightness and contrast, rotating, overlaying, etc.

Many word processors have the ability to directly create graphic images from sets of autoshapes (graphic primitives). It is also possible to create colorful inscriptions using built-in text effects.

You can visualize the numerical information contained in a table using diagrams, the creation tools of which are also included in word processors.

The most powerful word processors allow you to build different types of graphic diagrams (Fig. 4.19) that provide visualization of text information.

The most important

It is known that text information is perceived better by a person if it is visualized - organized in the form of lists, tables, diagrams, and provided with illustrations (photos, drawings, diagrams).

All kinds of lists in documents are drawn up using lists. Based on the design method, a distinction is made between numbered and bulleted lists. A numbered list is usually used in cases where the order of the items is important; marked - when the order of the items in it is not important. The structure distinguishes between single-level and multi-level lists.

To describe a number of objects that have the same sets of properties, tables consisting of columns and rows are most often used. The information presented in the table is clear, compact and easy to see.

Modern word processors provide the ability to include, process, and create graphical objects.
