Engage Students With Online Classroom Discussion Platform

This is a Sponsored post written by me on behalf of Collaborize Classroom. All opinions are 100% mine.

Collaborize Classroom: How would you like a free online learning platform for your students that is secure and safe?  Collaborize Classroom offers just that!  Teachers can extend classroom discussions in a private online community of students.  The online platform is safely structured to continue discussions, facilitate online learning groups, and allow students to share resources and engage in collaborative learning.

Watch a Collaborize Classroom Video to see how this happens:

This online collaborative learning provides deeper participation inside and outside the classroom as students are engaged in online discussions, activities, and assignments.  Students can share resources and engage in discussions that will result in a richer educational experience.

What’s great is that teachers can set up their Collaborize Classroom site in just minutes.  They just need an email address to utilize this free online learning platform that complements classroom discussions and encourages discussion, participation, and engagement.  Teachers can also create online lesson plans using free resources.  Here are some of the free resources available:

  • Do’s and Don’ts for Student Forums
  • Rethinking Your Role
  • Art of Asking Questions
  • 5 Activities with Collaborize Classroom

The platform is not meant to replace traditional instruction but helps to facilitate learning groups in a safe environment.  All of the sites are secure and have a password protected process.  The password is known only by teachers, students, and those who are invited to join the site.  All information and data is protected and safe!

Collaborize Classroom is free, allowing teachers to accomplish more than they could otherwise, and the free resources are a valuable addition to using this online learning tool.  The web-based technology provides endless possibilities for student learning.  In my opinion, this is a great way to encourage student engagement, especially those who are shy and don’t talk in class.  Most students are online at home anyway using social networking.  This platform fits right in with the way they communicate online socially.  And with the current economic crisis, the fact that this is free enables any teacher to use this platform.

Science Fact: Difference Between Sweet Potatoes & Yams

Although sweet potatoes and yams are both flowering plants (angiosperms), they do not have a botanical relationship.  Here are some facts from the Library of Congress:

  • Sweet potatoes have two embryonic seed leaves (dicot).
  • Yams have one embryonic seed leaf (monocot).
  • Sweet potatoes come from the Morning Glory family (Convolvulacea).
  • Yams come from the Yam family (Dioscoreaceae).
  • Sweet potatoes can be either firm or soft.  The soft variety is what we call “yams” in the United States.
  • Yams are starchier and drier than sweet potatoes and are native to Africa and Asia.

Firm sweet potatoes were introduced in the U.S. before the soft variety.  When the soft variety became available, they were called “yams” to differentiate between the two types.  Today, the USDA requires that potatoes with the label of “yam” also have “sweet potato” on the label because they are really sweet potatoes and not yams.
