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.
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.
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.
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.
