TES Teach with Blend Space
This is a favorite of a lot of people in the EdTech world. For Blended Learning purposes (think flipped but not completely), this resource is a big one. You can house a series of steps for your students all in one easy to navigate, and use, hub for a self-contained lesson. Add content (documents, video, images, etc.) from your computer or the web, and provide guidance for students. The resource is shareable and embed-able (as you can see below) and makes complex tasks with numerous steps easy for students to grasp.A link to the above file if you'd like to see it in a new tab:

Actively Learn
I'm a huge fan of EdPuzzle for videos (forces students to answer questions about the video before proceeding) and Actively Learn works very similarly but with articles and primary source documents. Have students answer questions as they read as part of their check for understanding. Want them to discuss items while they are reading (What? Thinking...while they are reading?), create the space for them. Want them to take a poll within the document at any place to gauge their opinions or understanding? Well....lets' do that!! It's one of those products that asks you to create a classroom and have students sign into it. But it is well worth it. Ken Buck at NU has been giving it a go as of late and he reports its an excellent resource for Primary Source documents and his students' understanding of them. There are a ton of features and options and Actively Learn walks you through the process in an easy to understand way.With Actively Learn, you set the pace with students, get them to answer all the questions in a rich manner, and allow for a deeper understanding of course material.
