TE year1sourcebook/year1 unit2 Topics of Study in the Unit
In this unit, you will learn to create learning resources using different digital tools, in different formats - text, image and audio-video. You will also learn to create digital presentations. You should create resources on the same topic on which you accessed internet resources in Unit 1 and try to make your resource richer and more useful for your learning.
Concept mapping
Think about the word 'plant'. Now think of all the words that that come into your mind when you think about the word plant. List these words in your notebook. Some of the common thoughts/words that would come into mind when thinking about plants are: Water, photosynthesis, leaf, flower, root, stem, soil, sunlight, carbon dioxide etc. These words can represent concepts connected to 'plant'. Concept is an abstract representation of an idea formed in the mind. For example, one concept for plant is that of it being a 'living thing'. Another concept could be 'creating energy' etc.
Learning often consists of understanding the concepts that underlie an activity, or an event or an idea. The linking of related concepts enables the forming of a 'concept map' in our mind, which represents our understanding of the topic or theme.
Concept maps can be an effective way of creating a text resource that can be organized in the form of a map or tree of ideas. It provides a pictorial overview of the concepts, related concepts / sub-concepts for a topic. In the map, you can link to additional resources, add annotations, graphically organize ideas through links etc. Concepts acquire power and meaning when they are connected to other concepts. Hence, organizing the concepts relevant to your topic is an important first step of generic resource creation. Concept mapping can be used to build skills in students for ideating and organizing ideas; you can use it for your teaching. It is a great tool to help organize your thought processes when writing.
Freeplane is a FOSS application that can be used to create concept maps (image ); in this section you will learn to use of Freeplane.
Learning to use Freeplane
Freeplane is a free and open source software application that helps you create and edit concept maps, as a generic resource creation.
Creating a map
To learn working with Freeplane, you should first develop a concept map for any topic you want to develop a resource on. When you open Freeplane, the application opens a window with a box containing the text "New mindmap". This node, also called the "root node" will contain the core idea/ theme of the resource. Additional ideas are added by adding more nodes, called child nodes. The concept map gets built by adding further child nodes, for topics and sub-topics. Use the ‘insert’ key to create a ‘child node’ this is a sub-concept of your current concept. Use the ‘enter’ key to create a ‘sibling’ this is a parallel concept to your current concept. Thus you can create a concept map (image 9) with knowing just two functions – add child node (insert) and add sibling node (enter). The ideas you have about the topic, the sequencing of ideas and sub concepts, the specific points for each idea / sub-concept can be developed on the map.
Hyperlinking files and weblinks to any node on your concept map
You can embed a hyper-link on a node, such that clicking that node will open a page on the Internet or a file on your computer (image 11). This connects a node on your map to related resources you may want the reader to access. You can also use the keyboard short cut CTRL-K to insert a web-link and SHIFT-CTRL-K to insert a link to a file on your computer. Freeplane will open an input bar (image 11), in which you can type in the address. The link is indicated by a red arrow inside the node.
For instance, if you would like to display an image associated with a node, you can link the image file to the node and clicking the arrow, will open the image. You can link any file. You can even link a node to another concept map, this way you could link concept maps of topics related to a subject, to provide a connected perspective on these concepts.
Linking two or more nodes on your map
You can link two nodes (which are not otherwise related as parent-child) by selecting the two nodes and clicking CTRL-L. This will provide a curved arrow to connect the two nodes. You can use this to indicate a direct linkage between the concepts represented by the two nodes.
Adding notes and note window
To add a note to a node, you can click on the node, go to View--->Notes--->Display note panel; this will open a window in which you can type your notes (image 13). You can change the position and size of this note window using your mouse.
The 'notes' feature allows you to provide detailed explanations, examples etc to any concept in the map. This can help you detail out your thinking on a concept. Freeplane displays a yellow label in the node, for which you have added a note.
These are some basic functionalities of Freeplane. For more advanced functions, you should refer to the User Manual for the application. The Freeplane tutorial is available within Freeplane itself, which you can access any time by pressing the F1 function key. The tutorial itself is a concept map, and you should browse this concept map, not only to get help that you may require, but also as a lesson on how a concept map can communicate so much information in such a simple manner!
Typing Kannada in Freeplane
Freeplane will not allow you to type Kannada directly, you will need to change font family in Freeplane by the following:
- Go to Tools -> Preferences -> Appearance ->
- In the font family option select Telugu fonts and click on Okay.
- Freeplane may ask you to restart, after which you can type in Kannada.
Note:If you are using older version of Freeplane, this approach will not work. You need to type in Kannada in LibreOffice Writer and copy paste it into Freeplane, and change the font to Kannada for each node.
Saving the file
By default your concept map is saved by Freeplane as a '.mm' format file (image 16). However, the concept map can be saved in many other formats. You can export the map to a text document file (in .odt or .doc formats). You can also export the map as an image (in .png or .jpeg formats) or as a web page (in .html format)(image 17). The images (image 16, 17) show you how to save and export concept maps in Freeplane. While saving the file, Freeplane will display the file browser, to allow you to select the folder in which you can save your file. By default, the file is saved in your home folder.
You should make concept mapping a habit. It is a wonderful way to think and document your ideas.
| Student activity time - Create a concept map for your chosen topic. Insert child nodes and sibling nodes to connect related concepts and sub concepts. Insert notes where you would like to provide a more detailed description or annotation for a concept. Insert a web link to Wikipedia for the main concept (root node). Note that simply saving the file will save it with the name you have given in the root node. Like with any editor, you can both create new maps and edit existing concept maps using Freeplane.
You should save the concept map in your personal digital library, you could save in a sub folder called 'concept map'. You should also save/ export the map in different formats in this folder. References: Learn Freeplane |
The power of the digital concept map is that you can keep revising the nodes, adding and deleting, moving and copying nodes as you want. This makes the process quite dynamic, unlike a concept map drawn on paper. Once you have completed your concept map you can share it with your classmates for feedback with which you can refine the concept map still further.
Text editing
Objectives
- Understanding that text is also data and can be combined with other formats
- Using a text editor as a method of recording, editing and presenting data
- Understanding that concept map and text document can be combined
You will use the FOSS Office Suite application called LibreOffice Writer (LibreOffice Writer) to create a text document. Open LibreOffice Writer on your computer, through Applications → Office – LibreOffice Writer (image 18).
Entering and formatting text
You can enter text by simply typing into this document.
UNICODE font
In the case of languages which use a script other than Latin, you must choose only UNICODE font for the text entry. Non-UNICODE fonts are likely to not render correctly on a web page. This is not an issue in case of the Latin script, used by English, French and many other languages.
Formatting text
You can format your text in many ways either through Format--->Text (image 21) or Format--->Character (image 22) or by changing the parameters on the tool bar. Click on the Format menu option of LibreOffice Writer to see the options. Commonly used formatting includes selecting text to highlight it through the ‘bold’ ‘italic’ or ‘underline’ functions (image 24), changing the font color or size and adding text highlighting. All these functionalities are also available on the tool bar.
Inserting a numbered list
You may be making a list of items in your document. Instead of manually entering the numbers, you could use automatic numbering.
You can select Format → Bullets and Numbering and select the numbering type you want (image 26).
Inserting a table / box item
You may want to put a specific information inside a box to highlight it separately. You can also use box to provide additional information. You can select Table. Select number of rows and number of columns as ‘1’. You will get a box (which is nothing but a table with one row and one column). Enter your text in this box.
Inserting a hyper-link
You can provide a hyper link in your text document to a web page. Clicking this link in the text document will open the web page (this requires internet connectivity). Inserting hyper links in relevant places in your text document (image 30), allows you to lead the reader to web resources that supplement or complement the information you are providing in your text OER document. This way you need not provide information that is already publicly available, and instead focus on information or a perspective that is not available, in your document.
It is useful to have page number and name of your document on every page, this is specially useful if the reader wants to read a print copy. LibreOffice Writer allows you to easily insert this information at the bottom or top of each page. This can be done using Insert--->Footer (image 31). Once a footer has been inserted, you can go to the bottom of the page and insert multiple fields of information using Insert--->Fields (image 32). You can type any text in this footer, it will come on all pages. Other than page number, other dynamic information you can provide is the date/time stamp of the document. A similar method can also be adopted for inserting a header as well. Page numbers can also be inserted directly using Insert--->Page Number.
Continuing editing your text document
You can re-open this file any time to continue editing your text document using LibreOffice Writer. You can add, move, modify and remove text. You can format your text in different ways. In this way, you can keep enhancing your text OER on your topic regularly. This is an important difference
Power of digital text editing
You have seen that text is another form of data and text can be organized in different ways using different tools.
- When text is entered digitally, it can be edited easily.
- Text can be copied, pasted and formatted differently. Some features like copy-paste are available across most applications whereas some features of formatting are specific to some applications.
- A "plain text" editor like gedit allows simple entry of text, copying, cutting and pasting of text and is linear. It is purely text and no images can be added.
- But most text editors have more features. A text editor like LibreOffice Writer allows text to be entered, formatted and presented in different ways and designed for printing. The text document also can add links to other files or resources on the computer or the internet. It is the most advanced tool available for creating textual outputs.
- The concept map allows text to be represented and connected in a graphic way. A concept map also can add links to other files or resources on the computer or the internet. Nodes can be copied, pasted. Text in the nodes can be copied or pasted.
- In addition to this, presentation software, such as LibreOffice Impress is also available which allows combining text and images as well as embedding of videos to make a multimedia presentation.
Combining audio, print and images to tell a story
One of the most important advantages of OER is the possibility of creating resources in multiple formats - images being one of them. Images can be used standalone, or in a sequence as an animation, or in combination with text to create picture stories for communication. With increasing use of ICT, creating, editing and remixing image resources is becoming more and more prevalent. Availability of free and open source tools for creation and re-purposing of image resources can help the greater creation, re-purposing and publishing of image and animation OERs.
Inserting images in a text document (LibreOffice Writer)
One of the ways of making OER powerful and high quality is by suitably integrating multiple resource formats. Images can be embedded / inserted into a text document. The image and the related text enhance the value of the other in the document. select Insert → Image. LibreOffice Writer will open the file browser. Use file browser to select the image file of your concept map. The image will be inserted in your text document as shown (image 13).
you can add images to a text document. In the video, we have added text and image as well. It is also possible to provide links and references to an audio / video file in a text document to provide a multimedia experience to the reader. There is an important difference between images and audio/video when integrating with a text document. While an image is embedded within the text document, an audio or video file resides out of the text document in a file folder and is separately accessed to play. This is done by inserting a hyper-link to the audio file or video file in your computer, to the document. Clicking on this link will access the audio/ video and play it, using the audio/video player. While publishing on a web page, it is possible for different formats to be displayed on a single page. We saw earlier that file links and hyper links can be added to a text document; we use the same approach to link an audio/ video.
