Foreword

Standing at the forefront of the digital and AI revolution, the importance of coding and computational skills has reached unprecedented heights. In today’s professional landscape, whether it’s in the fields of medicine, space exploration, education, science, or business, no sector remains untouched by this transformative wave. To not just survive but thrive in the 21st century, basic computer literacy is no longer sufficient. Learners must evolve into “digital natives” who can fluently read, write, and communicate in the languages that machines and AI comprehend. Recognizing this imperative, the National Education Policy of 2020 (NEP 2020) has strongly recommended the integration of coding skills, computational thinking, critical analysis, and problem-solving abilities into the curriculum. Moreover, forward-looking subjects like AI, Data Sciences, Computer Applications, and IT have been introduced as elective subjects from grade 9 onwards. It wouldn’t be surprising if further transformative measures are taken even at the elementary education level. Uolo has introduced an innovative 360-degree program for a coding-focused computer science curriculum, known as Tekie, spanning grades 1 to 8. Tekie is a significant stride towards STEM education that aims at making learners future ready—enabling them with skills needed in the ever-changing, technology-driven, and dynamic 21st-century world. Tekie adopts a captivating and engaging approach to learning, in line with the recommendations of the NEP 2020. The curriculum is ingeniously woven into the thrilling adventures of Mel and Conji, fictional characters from the enchanting land of Avora. The Mel and Conji series epitomizes a modern method of acquiring Computer Science knowledge and honing coding skills and computational thinking. Tekie is a technology-empowered curriculum that encompasses a few key components: • • • •

Main Content Books: These introduce learners to the theory of computer science and the tools used in the field. Topics in AI are also covered, along with experiential and curiosity-based learning resources. Coding Book: Specifically designed to nurture coding skills, this booklet aligns with the experiential and contextual learning approach of the curriculum, fostering critical thinking and problem-solving abilities.

Animated Learning Videos: The program is powered by high-quality animation-based learning videos that deliver learning in an engaging manner. Teacher Manual: This valuable resource supports classroom instruction, ensuring that educators can effectively deliver the curriculum.

Introduction to Files and Folders When we go to school, we usually take a tiffin box with us. The tiffin box contains our food. A tiffin box can contain a variety of foods. Similarly, if we want to keep some information on the computer, files help us store it. A file is a collection of information. It is stored on a computer. Files can hold text, pictures, songs, videos, and much more. Now, we know that files store information. Let us take the example of the tiffin box. We keep our tiffin box in our school bag. In the same way, we can keep our files on our computer in folders. A folder is a container that can store files. Folders can be used to organise files and make them easier to find. They act as holders where you can group similar files together.

Think and Tell

To understand the concept of file and folder, we have taken the examples of tiffin box and bag. Can you suggest another example?

Creating a File We can type text in a text file. Let us learn how to create a text file. Steps to create a file:

Paint There are many beautiful things around us. You might like watching flowers, Sun, mountains, and many more things that surround you. The fun part is that you can draw all these on paper or a chart with the help of a pencil, crayons, etc.

We can also make all these beautiful things on a computer without using paper, colour, or pencil. For this, you can use a program called MS Paint or simply Paint. MS Paint, a short form for Microsoft Paint, is like a colouring book on the computer, where you can draw and colour pictures using different tools and colours. It allows users to create and edit simple drawings, digital art, and images using various tools like brushes, shapes, and colour palettes. Did You Know?

Dan McCabe created a colouring book on the computer called MS Paint.

Introduction to Text Editing In the previous chapter, you created a document on Waste Management. You also learnt how to create, save, search, open, and share a document. In this chapter, you will learn how to edit text in documents. Text editing in Google Docs is the process of making changes to the text to improve its clarity and accuracy. It can also include copying, deleting, and moving the text.

Editing Text Once you type the text in any document, you may want to make some changes to that text. For example, if you want to add some text about the different Types of waste in the Waste Management document, we can do it by following the steps given below: 1. Place your cursor where you want to add the text. Press the Enter key. Chapter 5 • Editing Text Using a Word Processor

Cursor

2. Enter the name of the topic. In our case, it is ‘Types of waste’. Press the Enter key. 3. Type the text that you want to enter.

Selecting Text After typing the text, you can perform many operations on it, like deleting the text, duplicating the text, etc. For this, you need to first select the text. You can select a letter, a word, a block of text, a paragraph, or the complete document. Selecting text using a mouse: 1. A word: Double-click the word. 2. A paragraph: Triple-click anywhere on the paragraph. 3. A block of text: Click on the beginning of the first letter of the text, drag over the text, and then release the mouse button. 4. Complete document: Click on the Edit menu and choose the Select all option. Selecting text using a keyboard: 1. A character to the left of the cursor: Press the Shift + Left Arrow keys. 2. A character to the right of the cursor: Press the Shift + Right Arrow keys. 78

Copying and Pasting Text If you have a word that you want to use many times in your document, then instead of typing it again and again, you can just copy and paste it wherever you need it. In this way, you save time and do not have to keep typing the same word over and over. Copying text means duplicating the selected text and making it available for another location. Imagine you want to write the full form of “3 Rs” in the last line. Instead of typing it again, you can just copy it from the top part of the document and paste it at the end. Pasting means putting something you copied from one place into another place in the document. Steps to Copy the Text You can copy the text with a keyboard or a mouse. Using the keyboard, press the Ctrl and C keys together. Steps to copy the text using a mouse are given below:

1. Select the text that you want to copy. Chapter 5 • Editing Text Using a Word Processor

Moving Text While editing text, you might realise that some text is in the wrong place and needs to be moved elsewhere. Moving text means removing it from its original position and placing it at some other position in the document. We can move text using the Cut and Paste commands. The Cut command removes the text from its original position. Let us see how we can move the text. In the above document, for example, you want to change the position of the ‘Hospital wastes’ section from its original position and place it after ‘Dry and recyclable wastes’. Steps to move the text are given below: 1. Triple-click on the ‘Hospital wastes’ line to select the paragraph. Chapter 5 • Editing Text Using a Word Processor

Deleting Text If, in your document, you write something by mistake that you want to remove, then the Delete key is used. The Delete key is used to erase a word, line, or paragraph that you want to remove from your document. For example, in our document, we want to delete “it’s” and replace it with “it is”. To do that, we will follow the steps below: 1. Select the text. 82

The word “it’s” is replaced with “it is” in the document.

Think and Tell

How can you replace text without deleting the original text?
