On many web-based applications, such as glogster, prezi, youtube, crocodoc, etc, you can retrieve an embed code. It is usually under the "Share" link. You will usually find a link that says "get the embed code". If you click that link, you will be able to get the HTML code, which you can copy and paste in wikispaces.
Now that you have the code, go back to wikispaces. Click "Edit" on the page you'd like to embed it on, then click the "widget" box, scroll down to "other" and insert the code. If you want to embed a youtube video, you will need to choose "video"instead of other under "widget".
