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.
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.
There are only 4 rules in my classroom. The four rules are 1) Be respectful - I will always talk to students respectfully so there is no reason for students to talk to either myself of their peers with disrepect. 2) Always sit in your assigned seat - seating assignments are always projected in the front of the room so there is no reason to be confused about where to sit. No negotiations. 3) No talking during independent time - this doesn't need much explanation. 4) Technology is used for learning. Their devices should only be used to watch instructional videos otherwise it's too easy to get sucked into the vast abyss of the internet.
Communicating and collaborating with both colleagues and students' families is crucial in a blended environment. This is especially true if a teacher is doing something that looks very different from other teachers at his school. Check out how Jeff communicates and collaborates with both his colleagues at school and his students' families and how his methods of communication and collaboration have evolved over time.
