What's wrong with punitive worksheets?

Punitive worksheets punish learners for missing questions, lack immediate feedback, and promote massed practice. It's time for better assignments.

Our assignments were designed to optimize learning.

Mastery-based reviews to guide study sessions...

Most learners don't know how to properly study, and those that do often don't know what to study. Our reviews walk learners through course material in a manner proven to optimize knowledge retention.

Emily Carroll
“Every single week, students would spontaneously, unsolicited post in my discord channel ‘This OpenClass thing is great’, ‘I love this OpenClass thing’, ‘Can we have more OpenClass assignments?’ and if I haven’t prepared one for a week, there would be messages popping up after lecture, ‘Is there OpenClass this week?’, ‘When is it going to be available?’. My students had a great reaction to it.”

“Looking back two years ago when we started working with OpenClass, I couldn’t be happier that we went with OpenClass. The improvements that it led to our program and our student success rate is incredible.”

“Our teachers love the platform. It has reduced the individual workload of the teacher while maintaining the collective quality of education in our program. Our teachers love the metrics and all the data they receive from OpenClass. It allows them to make data-driven decisions on how they want to proceed in their classes, and it has facilitated differentiated instruction like no other platform we have used.”

“As educators, comprehensive review is something we all want to provide, but it can be difficult to deliver. OpenClass makes it easy — far easier than any other tool I’ve used. Feedback from undergraduates and graduates was overwhelmingly positive. Unsolicited, students repeatedly reached out to let us know how useful they found the review and mastery activities.”

“I was very impressed by OpenClass. I was impressed by the aesthetic of the interface—it was very beautiful to look at. I was impressed with the statistics that I got out of it afterwards—I could quickly look and see who'd finished, when they'd finished, and drill down and see details of what students had done—that was fantastic. I think it's a fantastic tool, and I think it fills in a niche that nothing else we have fills in.”

“The interface is attractive, it's user-friendly, and the instruction is very, very clear. I basically just spent like half an hour or an hour trying to learn how to build a class and I was able to do it. One very interesting thing I noticed is that not too many students noticed that they leave D2L, so I think that speaks to how well OpenClass is integrated to the D2L system.”
