We don't use text books in our class, we make them. Each student is given a binder at the beginning of the year. The binder becomes a reference book for the students as they fill it up with the lessons they have completed. Many standard textbooks have become a diluted hodepdoge of information, hard for most students (and even myself) to decipher. This binder allows me to create a resource tailored to my students.
I was spending an hour every day filing students' graded quizzes when we realized, "Why are we doing all this filing? Students could easily do this themselves." Since the number one thing we are trying to get students to do is take ownership over their learning, we decided to have students file their own papers, cutting down on a lot of menial work for us and giving students a chance to see a physical record of what they had and had not mastered.
The most common answer I give students when they ask me a question is "look at your notes." The course is designed so any question in the practice problems or mastery quiz have been directly addressed on the current video lesson or a past one. Because the design of the lessons has been created with this intentionality, it's easy to refer students to the exact place in the notes they can find their answer. It's been a challenge to not jump in and immediately offer students help, and many get frustrated in the moment, but over the course of the year students develop strong independence in their learning, able to use their notes, peers, and online resources to find the answer they were looking for.
Correctional Assignments provide another layer of practice for my students who fail a quiz before re-attempting to master the topic. The process is simple - my students complete the Correctional Assignment and then re-take the mastery quiz. My students can follow this process as many times as needed until they pass the quiz and achieve mastery. For this reason, I use IXL.com and Kuta Software for Correctional Assignments, which both generate infinite sets of practice problems.
