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.
Keeping students motivated is very important in a self-paced course. Scholar Dollars is a strategy I developed to reward my students for working hard and making progress in the course. The concept of Scholar Dollars is pretty simple. Every time a student passes a Mastery Quiz, they receive five Scholar Dollars. Students receive 15 Scholar Dollars for passing a Level Test. Scholar Dollars can be used to buy school supplies, snacks, or even a pizza party. On random days, I switch up the payouts on Scholar Dollars - doubling the amount given, only paying for 100s on Mastery Quizzes or Level Tests, or giving all the Scholar Dollars earned on that day to one lucky student picked by lottery at the end of class.
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.
Truly understanding science requires my students to think in ways they might not have experienced before. Conceptualizing something that our eyes can't always see is difficult, and so it's valuable to provide graphic organizers, visual models, and other support tools as resources that my students can access while diving into content. One of the richest ways to get students to build their own methods and approaches to solving problems is to allow them to think on paper. Lessons involving direct instruction are always broken into small segments with short, casual writing periods built into the end of each one. These Quick Write Summaries are meant to focus on content construction and are free of structural analysis. I don't grade them, but I'll always help students put together their thoughts and present them with questions that guide them to the answer. Writing-to-learn strategies like the Quick Write Summary help visual learners with long-term comprehension of scientific terminology and sets the stage for students demonstrating their knowledge through writing in future assessments.
