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.
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.
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.
The Class Website is one of the most essential tools in providing my students 24/7 access to class content and information. The Class Website hosts all of my videos, lesson packages, answer keys, and correctional assignments, as well as any other relevant information I want to disseminate. The Class Website decentralizes the teacher as the holder of knowledge and empowers my students to access content whenever and wherever they need it.
