To give students greater independence, there is an answer key for the practice problems of every lesson. I know what a lot of teachers are thinking at this point: what if the student just copy all their answers from the answer key? As an Algebra teacher told me when I asked them the same question before starting flipped mastery, they'll just fail the mastery quiz. It only takes a few correctional assignments for them to realize that the answer key is there to check answers, not copy them.
My blended classroom is based on the Flipped Mastery model (please see the "Introduction to Mastery Based Learning" strategy video). When my students think that they have mastered the skills and concepts in a particular lesson, they show their completed notes to me or my co-teacher and get a Mastery Quiz. Students then head to the Mastery Zone, which is a section of the classroom reserved for students taking Mastery Quizzes and Level Tests. There is no talking in the Mastery Zone and the only technology permitted is a calculator. If they achieve at an 80% or higher rate, students move forward in the curriculum. If not, they review the concepts and materials in the lesson and re-take the Mastery Quiz in the Mastery Zone when they are ready. The Mastery Zone assessment strategy is a concept I adapted from the Algebros Flipped Mastery program.
By its very nature, learning in a self-paced classroom with digital resources can be an isolating experience for some students. While I want my students to take personal responsibility for and ownership of their learning, I also want them to learn essential collaboration skills and to leverage social learning to grow as people and as students of Mathematics. Buddy Time is a grouping strategy that requires my students to collaborate with peers working on the same lesson at a prescribed point in each lesson. During Buddy Time, students can collaborate or discuss their work with other students at their tables and they can use their collective knowledge and skills to help each other move towards mastery.
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.
