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 allowing my students to assess other students' work and then providing them with a Student Lab Development Rubric to evaluate their own work, they learn to design and refine high-quality experimental procedures. The Student Lab Development Rubric is one of the tools I use to help students build the experiments they've created and then display results and lab analyses. When students are the ones dictating how they will conduct their experiments, they invest more fully in the activity and come to realize that science involves constant critical analysis and reiteration. I like to move conversations away from "right" and "wrong" and more towards how we can improve each component of our lab activities. Initially, some students feel uncomfortable identifying that their work isn't up to the high standards of the rubric, but over time most come to realize that this process helps them improve their final products and understand the underlying purpose behind labs.
Chemistry is a combination of the comprehension of scientific content and the application of mathematics to those concepts. My students have to be prepared to think deeply about difficult concepts the minute they step into my room. Starting the class with a relevant "Catalyst" helps them initiate their own thinking processes in preparation for a productive day in the same way that biological enzymes catalyze chemical reactions. During The Catalyst, I model my thinking process for how to approach a mathematical problem by having my students identify the key steps in the calculation and establish a foundation that students who struggle with math can fall back on when they're confused.
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.
