PRESENTATION SOFTWARE IN TEACHING-Impress and PowerPoint
Slide presentation software such as PowerPoint has become an ingrained part of many instructional settings, particularly in large classes and in courses more geared toward information exchange than skill development. PowerPoint can be a highly effective tool to aid learning, but if not used carefully, may instead disengage students and actually hinder learning.
Potential benefits of using presentation graphics include:
· Engaging multiple learning styles
· Increasing visual impact
· Improving audience focus
· Providing annotations and highlights
· Analyzing and synthesizing complexities
· Enriching curriculum with inter disciplinary.
· Increasing spontaneity and interactivity
· Increasing wonder
OPEN OFFICE IMPRESS
Apache Open Office Impress, a part of the Apache Open Office office suite and developed by Sun Microsystems, is an open source presentation program compatible with and similar to Microsoft PowerPoint.
With this versatile application we can create a series of "slides" that can contain text, images, audio, or even video. We can customize the navigation and link from one slide to any slide in the collection, progressing in a non-linear fashion. Open Office Impress shows can be presented manually, by clicking on the space bar to progress to the next slide. You can also create a stand-alone self -running "show" with the application. It can export presentations to Adobe Flash (SWF) files allowing them to be played on any computer with the Flash player installed. It also includes the ability to create PDF files.
A presentation consists of page(s) that can be seen on the computer screen as normal and with the use of a projector, can be seen on the wall or on an external screen. Normally, a laptop is used since it has good portability.
Impress is like a SLIDE SHOW. One page after the other is projected.
A page that is projected is called a SLIDE. The following can be included in a Slide:
2. 3-D graphics
3. Bullets and Numbered Lists
4. All the normal stuff that is in a word processor (Writer) and in spreadsheets such as bold, colours, text alignment, borders, drawing, templates (master slide) , etc.
Notes can be added to a slide that are not projected but can be seen by the presenter
PowerPoint was the first presentation software designed for Macintosh and Windows It integrated the use of graphics and animations early on in its development, with more recent versions allowing the user to embed entire videos
Classroom response systems can improve students' learning by engaging them actively in the learning process. Instructors can employ the systems to gather individual responses from students or to gather anonymous feedback. It is possible to use the technology to give quizzes and tests, to take attendance, and to quantify class participation. Some of the systems provide game formats that encourage debate and team competition. Reports are typically exported to Excel for upload to the instructor's grade book.
PowerPoint is an effective pedagogical tool in the classroom. It can be used in the classroom for initial teaching, for student projects, for practice and drilling, for games, for reviews, and for tests.
Benefits for teachers
· Teachers can use PowerPoint presentations to enhance the effectiveness of classroom instruction in many ways and in every subject area.
· Teachers can modify lessons and use them over and over again. Therefore, teachers save time on handing out instructional material, writing on blackboard, repeated speech and so on.
· PowerPoint can enrich the information in a lesson, and make the presentation more organized and flexible.
· Main points can be emphasized by using graphics, animation and sound.
· PowerPoint can be used for content review.
· Rather than handing absentee students written notes of a lesson they missed, you can replay your lesson or presentation using a slide show. Absent students receive the same instruction as those who are present, so they do not fall behind.
· Teachers can share lessons and presentations simply using a file-sharing system or flash drive. Teachers can share the workload of creating presentations. Furthermore, a student seeing more than one teacher's presentations is exposed to more than one point of view.
GSat-3 or EDUSAT is the first Indian satellite built exclusively for serving the educational sector. It is mainly intended to meet the demand for an interactive satellite based distance education system for the country.. EDUSAT was from Sriharikota in 2004. Initially it was proposed to use the facilities in four different states for reaching different target groups. In Karnataka State the Edusat is being used to supplement classroom teaching in all the 850 elementary schools of one district. Different Pilot Projects under EDUSAT are proposed on experimental basis in four States the country for understanding the process and implication of Satellite based Education program in different sectors. Karnataka, Kerala, Madhya Pradesh and Maharashtra are the four States where EDUSAT program are implemented in the current year. In each of these States a particular target and area has been identified for utilization of EDUSAT .
India’s first broadband network on EDUSAT for schools - - ViCTERS (Virtual Class Technology on Edusat for Rural Schools) – inaugurated by the President of India on 28th July, 2005 in Thiruvananthapuram has revolutionized classrooms through interactive IP-based technology. Kerala has since demonstrated how Edusat could be used to successfully empower teachers. The state is also all set to kick start a non-interactive channel in DTH (Direct-to-Home) to be brought to all its 12,500 schools wherein 50 lakh children stand to benefit. ViCTERS 12 hour educational channel for school education was officially inaugurated by Hon. Chief Minister of Kerala Shri. V.S Achuthananthan on 3rd August 2006. The channel is unique in the sense that it caters to students & teachers on a need based manner. The programmes are aired on demand, sensitive to school curriculum and even time-table.
Gyan Darshan offers interesting and informative programmes for different categories of users such as pre-school kids, primary and secondary school children, college/university students, youth seeking career opportunities, housewives and adults. These programmes are contributed by major educational institutions including IGNOU, UGC/CEC*, NCERT/CIET*, Directorate of Adult Education, IITs, TTTIs and other educational/developmental organizations. The time slots are convenient and the programmes are prepared with the help of experts in the field and experienced production teams. Programmes from abroad are also broadcast to offer the viewer a window to the world.
Gyan Darshan transmissions, uplinked from the earth station of EMPC-IGNOU New Delhi, can be accessed all over the country throughout the year and round the clock without any break. Gyan Darshan signals can be conveniently received without any special equipment.
This is the main Gyan Darshan channel. Its programmes include the ‘country wide classroom’ produced by CEC/UGC, ‘technovision’ produced by IITs and ‘Bhasha Mandakini’ produced by the Rashtriya Sanskrit Sansthan. Bhasha Mandakini, launched on September 5, 2003, Under Bhasha Mandakini, the ‘Sanskrit’.
E Content Development
As the world of IT started to grow rapidly, the technology gave a new dimension of education; it was in the early 90's where the letter "e" started to be used in the world of education. Yet, the new concept of education was not accepted by most of the traditional learning sectors.
It was a tough time, a lot of efforts and development researches were conducted until the word "eLearning" came out to see the light. By then, learning organizations, governments and individuals started to accept and use the new term; where IT companies started to develop, add and modify the new concept in cooperating with the main targeted audiences to get the eLearning into its perfect shape.
Some salient features of e-content are bi-sensory learning experience, digital convergence of text, image, audio, video, animation etc. to create the effects of multimedia, accessibility, reusability, interoperability etc.

Basics of Graphics, Audio and video editing – Gimp/Audacity/Kdenlive
The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing.
Computer graphics can be used in many disciplines. Charting, Presentations, Drawing, Painting and Design, Image Processing and Scientific Visualization are some among them.
Basic concepts of Computer Graphics
Computer graphics is concerned with all aspects of producing images using a computer. It concerns with the pictorial synthesis of real or imaginary objects from their computer-based models. Video games represent a major use in the home of computer graphics. Computer graphics helps to create and manipulate pictures with the aid of computers.
Different types of Computer Graphics
Computer Graphics can be broadly divided into two:
· Non Interactive Computer Graphics/passive computer graphics: In non interactive computer graphics the observer has no control over the image. Familiar examples include the titles shown on TV and other forms of computer art.
· Interactive Computer Graphics: It involves a two way communication between computer and user. Here the observer is given some control over the image by providing him with an input device.
