How to Create a Podcast or Vodcast Part 2 of 3

Hello,
Today I will be covering the following steps:

3. Installing Audio Software to Record Your Podcast
4. Using Audio Software to Record Your Podcast

So, let's get started with installing the audio software.

3. Installing Audio Software to Record Your Podcast: You want to use the best possible free software to edit and prepare your podcast. The one I recommend is Audacity. It's free and a very good sound editor. It can be found by clicking on the picture above. Once you go to the site you want to download Audacity 1.2.6 Once you get to the site you will want to choose Audacity 1.2.6 installer and if the download does not begin, choose the option direct link Save the file to your desktop. When you are using the software in Audacity you will need to convert your sound files to an Mp3 and you will need to download the LAME encoder by going to LAME Mp3 Encoder Once you visit the site, you will need to choose the operating system you are using, then click on the LAME download page Toward the bottom of the page you will see the following picture. Click on the appropriate link on the site, and save it to your desktop. Next, you will go to your desktop and double click on the icon and it will ask you to run it, click run and follow the instructions. You will want to remember where you saved it, usually it will be in your Program files menu. Next, double click on the audacity icon on your desktop and you will see the following:

Open Audacity and click on Edit -> Preferences -> File Formats Now this is what you will see. Click on Find Library and follow the instructions. (Here is where you want to find the LAME Mp3 Encoder file, remember it is under Program Files)

4. Using Audio Software to Record Your Podcast: Once you have your software and the Lame Mp3 encoder is installed you are ready to test your microphone. You can either use a headset with a microphone or you can use a microphone and your computer speakers. Plug in your microphone or headset. The microphone is usually the red jack and the headphones is usually the black jack. Go to Start -> Control Panel and double click on Sounds and Audio Devices. Next, click on the Voice tab and click the Test Hardware button. Follow the instructions to test your microphone. For additional tips on settings to make your recordings great visit the following site Great Tips on Recording When you are in Audacity make sure "Microphone" is selected as the recording source in the drop-down menu on the mixer toolbar.

Go to Edit -> Preferences -> On the Audio I/O tab make sure your sound card is selected as the device for playback and recording. In the Channels drop-down box under Recording, choose 1 (Mono). You can use stereo if you want but it will make your file larger and you want to try and keep it as small as possible. Under the Quality tab make sure you choose 44,100Hz as the Default Sample Rate and 16-bit as the Default Sample Format. Under the File Formats tab make sure you choose WAV (Microsoft 16 bit PCM) as the Uncompressed Export Format.

Now you are ready to record. Check on the microphone Meter toolbar in Audacity and you should see a red level indicator moving when you start recording. You can talk into the microphone and make adjustments to the volume until it looks like the picture below.




Now, your almost ready to record. Down below in the picture you will see the featured buttons to start your recording.



Simply push the Record button and you can start talking. When your done recording press the yellow square button to Stop the recording. If you want to edit your file, where you want to cut out parts of your recording or delete parts. You simply edit out parts by clicking and dragging to highlight the part you want to remove. Select Edit and choose either Cut or Delete. The part you want to edit will turn a grey shaded color. If you want to keep only one section of a recording, highlight that section and select Trim from the Edit menu. Take a look at the picture down below and you will see how to edit your clip.

You can also record many multiple tracks to add to your podcast, which is one of the many features you can't do with movie maker 2.Ok, next week I will be talking abou the final steps in your podcast, step 5. Turning your Podcast into a Vodcast and step 6. Publishing and Promoting. I will also be covering how to add music to your podcast and how to convert your WAV file to an MP3 so you can post online. See you next week.

How to Create a Podcast or Vodcast Part 1 of 3

Greetings,

Today I am blogging about podcasting and vodcasting. According to wikiipedia, podcasting is defined as a series of digital media files (either audio or video) that are released episodically and downloaded through web syndication. It is a series of digital audio files, usually MP3 that can be downloaded on a regular basis automatically. It's kind of like having your own radio station and you are the broadcaster. Vodcasting or Videocasting is defined as online delivery of video, or using still digital pictures in a video. There are four steps to creating a podcast: plan, produce, publish, and promote. The detailed steps into creating a podcast include the following stages:

1. Planning

2. Gathering Ideas

3. Installing Audio Software to Record Your Podcast

4. Using Audio Software to Record Your Podcast

5. Turning your Podcast into a Vodcast

6. Publishing and Promoting

This blog will break down these steps in a 3 - 4 week blog episode. In this blog episode I will be discussing the first 2 steps. 1. Planning and 2. Gathering Ideas

1. Planning: When you start to create a podcast you need to plan what you are going to say by scripting your words. You might want to have an introduction and a welcome. After you have your script then you can practice recording it. You want it to sound like a radio broadcast or a radio show. When you start a podcast it is important that you continue to create new and regular episodes for your listeners. If you are planning on your students to create podcasts, then you need to monitor the planning process to make sure students are well prepared before recording their podcast.

If you are going to create a podcast or vodcast, and put your students' voices in the project and upload them to the internet, then you are going to need a podcast/vodcast permission slip for their parents to sign. You also want to include a brief detail of what a podcast is, (this will educate the parent) and how only the voices will be used. Now, back to planning your podcast: Here are a few questions you want to ask yourself while you are planning your podcast. What do you want to communicate to your listeners? What do you want your students to communicate in their podcast? How often do you want your students to create a podcast? What do you want to teach your listeners? What type of action do you want your listeners to take during the podcast?

2. Ideas: What topic or idea do you want to share with your listeners? You want to create a 3 -5 minute podcast for your listeners maybe once a week or once every 2 weeks. You want your listeners to always want more from your future podcasts. Here are some additional web sites of sample podcasts:

Elementary Schools:
http://www.kid-cast.com/
Willowdale Elementary School
Wells Elementary School
Jamestown Elementary

Middle Schools:
Harrington Middle School
Mabry Middle School
Twin Valley Middle School

High Schools:
Amphitheater High School
Coral Gables High School
Briggs High School

Educational Podcast Directory You can also go to Itunes and search for student podcasts. You can also go to google and search for podcasts as well. Here is a Podcast Legal Guide you may want to review to make sure you follow all the legal guidelines in podcasting http://wiki.creativecommons.org/Podcasting_Legal_Guide

Here are 25 more ideas that you may want to think about for your podcast or vodcast:
1. Visit http://www.pppst.com/ – This site has thousands of teaching PowerPoints that can be used for Podcasting
2. Talking books
3. Having students read a book
4. Vocabulary lessons
5. Oral tests
6. Test Reviews
7. Spelling lists
8. Pledge Allegiance
9. Numbers and Alphabet songs
10. Recording lectures
11. Introduction to staff
12. Faculty meetings
13. Communications to parents and community
14. Homebound lessons
15. Announcements
16. Lecture notes
17. How to:
a. Check out books in the library
b. How to use the Grade book program
c. Validate grades
d. Fill out forms
e. Do a certain project
18. Book reviews
19. Field trips
20. Student forms
21. Staff Development
22. Dictation
23. Student information
24. Registration information
25. Senior information

Hope these ideas help you out, as you plan your podcast. Next week, I will cover step 3. Installing Audio Software to Record Your Podcast and step 4. Using Audio Software to Record Your Podcast. See you next week.

How to Turn any Room into a Presentation Room with Your Computer Part 1


Hello,

Today I am blogging about how to set up a microphone PA system in your classroom. You can turn any room into a presentation room by using your computer, and your computer speakers.

 I think teachers should create a Great Experience for their students, and having a microphone, and speakers in their room does that. You can have students give presentations, and they can hear their voice amplified over your speakers. You can teach your students interview skills, and presentations skills. You can also teach them how to defend proposal, and premises in front of the class.

From my experience of visiting different elementary schools, I am finding about less than 1% of the teachers use microphones in their classrooms. So this can be a great way to help your students in having an unforgettable experience that they will never forget, while teaching them presentation skills at a young age.

It is as easy as connecting a microphone to the back of your computer through your sound card. You want to make sure you have computer speakers connected to your computer, so the sound can come through them. As you can see in the picture, you connect the round metal tip to the back of your sound card. At the end of the cord, it is usually color coded to match the color of your jack input in your soundcard. If it is not, then you are looking for an imprint or picture of a microphone on the back of your sound card.

Your other options are to buy a USB Microphone and just plug in the Microphone into a USB port. Many USB Microphones come with software you have to install before you connect the microphone to the computer. Once you do this, then all you have to do is to go into your sound and audio devices in your settings on your computer to turn on the microphone. To do this you have to left click on your green start button on the bottom left side of your computer screen. There are two views you could be using on your computer. (To enlarge the pictures you need to rapidly double click the pictures with the left side of the mouse)

The first view is the classic start menu and the second view is the new start menu. Let’s go over the first one, the classic start menu. Older computers have this menu and it looks like this Click on control panel and you are looking for an icon that says Sounds and Audio Devices Once you find it, rapidly double click with the left side of the mouse and you will see a menu like this

The second view is the newest view for Windows XP, Vista, and Windows 7. Left click on the green start button on the bottom left of your screen. You are now looking for this button on the right side of the start menu. You will need to left click on the control panel button. Next, you will see this menu You will need to rapidly double click with the left side of the mouse on the Sounds, Speech and Audio Devices. This is the next menu you will see after you have opened up your Sounds and Audio Devices Options. You will be on the sounds tab button. You can place a check by the Place volume icon in the taskbar and then you want to click the button below that Advanced and you will see a menu like this You will want to uncheck the box that says Mute under the button that says Microphone, so you can hear sound coming out of your microphone. Do not worry about the other checks. You can close the Playback Control box and close the Sounds and Audio Devices Menu. You should now be able to talk with your microphone and hear the voice sounds projecting through your computer speakers.

Hope this helps if you have any other challenges while setting this up, please visit this following resource site: http://atr.k12.hi.us/tutorials/tutorials/sound/soundpt1.htm#one We will see you next week with part 2 on how to create set up a four professional wireless microphone system in your room for under $200. That's right I will be giving you all the details of where I purchased my professional wireless microphone system fron under $100. See you next week!
