Introduction MI Introduction (LSI Quadrant I): Introduction (LSI Quadrant I): Show: Image of the IBM DOS screen. SAY: The original IBM PC was a poor, little thing. It didn’t say, sing, or play IT: Computer Maintenance: Multimedia Lesson Plan Copyright © Texas Education Agency, 2011. All rights reserved. 2 anything. It didn’t even display graphics well, or show more than four colors at a time. Information was formally defined as rows of text, and there were no video or sound cards in the PC. ASK: Has anyone ever created a PowerPoint presentation? (With PowerPoint we can paste pictures and add sound; that’s an example of multimedia.) SAY: There are, in fact, industry standards for what types of hardware make up an official multimedia PC. SAY: Multimedia also has become an integral part of the Internet. ASK: What features on an Internet website are examples of multimedia? (animated icons or banners, music and demo links) SAY: The real advantages of multimedia CDs, like a DVD movie, are sound and visuals combined with text and easy, quick access to all of it. ASK: Who has a DVD player at home? Does it allow you to skip to any scene of the movie? (These are some advantages of multimedia.) Outline MI Outline (LSI Quadrant II): Instructor Notes: I.

Virtual Reality (slide 26) IT: Computer Maintenance: Multimedia Lesson Plan Copyright © Texas Education Agency, 2011. All rights reserved. 3 VI. Have students complete Labs 1-3. VII. End the lesson with the Multimedia Exam. Application MI Guided Practice (LSI Quadrant III): 1. The teacher demonstrates each lab principle. 2. The teacher maintains direct supervision in the lab, providing guidance when warranted. MI Independent Practice (LSI Quadrant III): 1. Students work individually on lab assignments, demonstrating their skills in identifying and discussing the various lab requirements and results. Summary MI Review (LSI Quadrants I and IV): Checking for understanding (Q&A Session) (slide 27) Q: How has multimedia advanced through the years? A: The original PC did not have a sound card or video card, so all that was displayed was text. Now we have speakers and color graphics on our screens. Q: What features should you look for when choosing a video card? A: Resolution, color depth, and refresh rate. Q: Which features should you look for when choosing a sound card? A: MIDI support, FM and Wavetable synthesis, sound blaster compatibility. Evaluation MI Informal Assessment (LSI Quadrant III): Monitor student progress during independent practice and provide independent reteach/redirection as needed. MI Formal Assessment (LSI Quadrant III, IV): Use the Multimedia Exam and Exam Key. Extension MI Extension/Enrichment (LSI Quadrant IV): Students that have mastered the lab assignments can peer-tutor students (one-onone) that are having difficulty individually completing the lab activities.

You will go through all the steps of the installation. Resources: The following resources will be required: • PC Tool Kit • Anti Static Wrist Strap • Personal computer (PC) • video card of your choice NOTE: Before installing a video car, turn off the computer, unplug the power cable and remove the cover from the computer case. Make sure you and the computer case are grounded. Step 1 Select the expansion slot on the system board where you want to install the video card. Step 2 Remove the expansion slot cover from the back of the computer case. The cover is usually held in place by a small screw. Step 3 If necessary, use cables to connect the video to other devices. Step 4 Place the video card in the expansion slot. Press down firmly and evenly across the top of the card until it is securely inserted in the expansion slot. Step 5 Secure the video card to the computer case using a small screw. Then replace the cover on the computer case. Step 6 When you have finished installing the video card, your computer may automatically detect and set up the video card for you. The video card may include and installation program you can use if your computer does not automatically detect and set up the video card.

Step 2 Remove the expansion slot cover from the back of the computer case. The cover is usually held in place by a small screw. Step 3 If necessary, use the jumpers or switches on the sound card to adjust the settings for the sound card. Step 4 Place the sound card in the expansion slot, pressing down firmly and evenly across the top of the card until it is securely inserted in the expansion slot. Step 5 If necessary, connect the audio cable to the sound card. Then connect the audio cable to the sound card. Step 6 Then connect the audio cable to the CD-ROM drive. This allows your computer’s speakers to play sound from compact disks. Step 7 Secure the sound card to the computer case using a small screw. Then replace the cover on the computer case. Step 8 When you have finished installing the sound card, your computer may automatically detect and set up the sound card for you. If your computer does not automatically set up the sound card, you can consult the sound card documentation for information about resource settings such as IRQ’s, DMA channels that the card requires. Make sure other devices are not using the same settings. IT: Computer Maintenance: Multimedia Lesson Plan Copyright © Texas Education Agency, 2011.
