I really like the idea of using problem-based learning in my math class. It helps students see the relevance of what they are learning.

I appreciated the section on rubrics. I've found that a detailed and clear rubric saves a lot of headache when grading. I also like the idea of using the rubric and having students do a self-evaluation or peer evaluation on an assignment. This is a method of active learning as well.

Active learning takes more of the instructor's and students' time. This can be met with pushback from both. It is important to remember that active learning is backed by research as more effective, so it is worth the time investment.

Active learning is the ideal format for effective learning. While lecture is traditional, especially in higher education, research has shown that is is less effective than active learning. In an online setting, active learning can be accomplished in a variety of ways (asynchronous discussion/debate, group projects, etc.).

Multiple sources of feedback are important to properly assess if a course is designed efficiently. Make sure that the type of feedback received is relevant to the thing being measured.

I intend to use the "three clear points, three muddy points" technique to evaluate what part of the messaging is being conveyed clearly, and what needs improvement.

I like where it's emphasized that the feedback given to learners shouldn't focus on justifying the grade given. That's what the rubric is for. Instead, the feedback should help the student learn.

I try my best to do that in feedback I give. Often times, I'll record feedback as video so that what I'm referring to is more clear.

Well-built scaffolding allows the learner to use their prior knowledge and experiences to assist them in learning new material. 

I've found that when I teach 3D modeling, students who have a background playing with Legos, or even building blocks, have an easier time understanding some concepts when I relate those concepts with the concepts they used with those childhood toys.

There are different types of student behaviors and they can be tricky to detect online so instructors need to understand and monitor for those. I also learned about effective communication, particularly through email.

Asynchronous discussions are preferable in an online setting. Synchronous discussions can become difficult with large groups or factors like different time zones, slower readers, slower typists, etc. In all text-based discussions it's important to be aware that tone is important, and it is different than in person. Emojis, text formatting, and abbreviations like "LOL" can help signal intent.
