Have you been interested in taking a MOOC (Massive Open Online Course), but don't know where to find one or how to get started?

Class Central is a free MOOC aggregator that provides links to a wide variety of courses from universities like Stanford, MIT, Harvard, etc. (offered via Coursera, Udacity, edX, NovoED, and others).

The site allows you to search for MOOCs according to the course name, instructor, subject, start date, length of course, and course provider. Class Central also offers a "MOOC Tracker" service that will send you email notifications when a MOOC that is of interest to you becomes available.

MOOCs are a great idea for your students if your school doesn't offer advanced courses for a particular subject and they are also great resources for instructors and others. Try one and I think you will find out how they can be a benefit to you. I did!

The CareerTech Testing Center (CTTC) works closely with instructors, industry representatives and credentialing entities to identify and develop assessments and assessment preparation materials that are aligned with recognized industry standards.

Study guides are designed to help students prepare for the assessments. Each study guide includes:

Wizer is an educational platform that allows instructors to create quick, easy and fun digital worksheets, to share them with fellow instructors, and to keep track of student performance.

Nearly a year after releasing its Moments curation feature, Twitter Moments is now available to users.

Twitter Moments are curated stories about what’s happening around the world—powered by Tweets.  Originally, a user could click on Moments on their profile page to find curated stories, i.e News, Entertainment, Sports, and Fun, in a typical news format.

But now, it’s easy to create your own story with Twitter Moments.  I think this is a great way to share school events and activities and it could also assist with classroom discussion, especially when dealing with current events.

Either watch the video by Richard Byrne of Free Technology for Teachers or follow the directions from Twitter below:

How to create a Moment

There are three ways to begin creating your own Moment. You can access Moments through the Moments tab, your profile page, or through a Tweet detail. To get started all you need is a title, description, Tweets, and a selected cover image.

From the Moments tab:

1. From the Moments tab, click the Create new Moment button.
2. Click the Title your Moment field to give your Moment a name.Note: Titles can be up to 75 characters in length.
3. Click the Add a description field to type in a description for your Moment.Note: Descriptions can be up to 250 characters in length. 
4. Choose Tweets to add to your Moment: 
1. From the Add Tweets to your Moment section at the bottom of the page, quickly access content to select Tweets from Tweets I’ve liked, Tweets by account, Tweet link, and Tweet search prompts. 
2. To add a Tweet to your Moment, click on the checkmark icon 
5. Click Set cover to choose a cover image from one of your selected Tweets, or to upload an image from your computer. Drag your selected image to set a Mobile preview, click the Next button, then click the Save button.Note: To change your selected image, hover over the cover image and click on Change cover media. After you’ve set your cover media, the source will be credited below the image. 
6. Once you have Tweets in your collection, click on the up  or down arrow buttons  to the right of a Tweet to move it up or down.
7. Click on the delete button  to remove a Tweet from your Moment.
8. Click on the crop button  next to any of your selected Tweets to make an image selection for mobile viewing.
9. Click the Finish later button at the top of the page to save a draft.
10. When you are ready to make your Moment live, click on the Publish button at the top of the page.

From a Tweet:

1. Click the more button 
2. Select New Moment to add the Tweet to a new Moment.Note: Any completed Moments or Moments drafts you have in progress will also be listed in the drop-down to choose from.
3. Follow the directions above to complete your Moment.

• You can click on the Edit button under the Moment description to continue editing your Moment.
• Click the Tweet button under the Moment description to share your Moment with your followers. Note: The Tweet compose box will pop up giving you an opportunity to edit or add to the auto-populated Moment title and link in the compose box.
• Click on the more button  under the Moment description to send your Moment via Direct Message, and to view the copy and embed links to your Moment. Note: As you scroll through your saved or published Moment you will see a menu pop-up on the left hand side to conveniently Edit, Tweet, or Message your Moment.

Frequently asked questions

Can I make my Moments private?
When creating a Moment, you can select Share Moment privately, which will only make the Moment available to those who have the link. If you would like to make previously published or shared Moments visible to only you, select Unpublish Moment.

Can content in my Moment be reported?
Yes. Content displayed in a Moment, such as photos, videos, or Tweets can be reported. To learn about the various options for reporting components of a Moment, read our How to report violations article.

What happens if a Tweet I included in my Moment is reported?
If the cover or any of the individual Tweets of your Moment is reported to us and found to be in violation of the Twitter Rules, your account may be locked—even if you did not author the Tweet.
