I am a part-time college science instructor and part-time web developer for several non-profits. Do I even need to say how terrific it has been for the people I work with to take control of their web content using Concrete5? Probably not. Concrete5's flexibility and ease of use are well-known to readers of this forum.

It is time for me to tackle switching my course site,http://go101.org/, to Concrete5.

I am interested converting all my code that gives students instant feedback on their homework assignment questions to a Concrete5 block.

I am able to enter a wide variety of types of homework questions from (true/false, multiple choice, short answer, calculation, essay, matching) and give students automatic feedback on each question (right, wrong, you-made-a-common-mistake-and-here's-how-you-correct-it, or must-be-graded-by-instructor).

Here are my questions to the Concrete5 community:

1. Is there a block that already does this or something like this?

2. Is anyone interested in collaborating with me on a homework block?

I am very interested in making this a free block for educators.
