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.
Science can be messy and my students are often in such a rush to take care of the priorities for the next class that they forget to clean up their work and physical area appropriately. Closing Time reminds my students of their obligations for the end of a class period and standardizes a system that promotes personal responsibility for all class materials. During this time, I list all of the upcoming class assignments and events on the board, so that my students can begin thinking about future activities when they've finished cleaning up and closing down. Coupling this strategy with a tool like Remind 101 keeps my students aware of what is expected of them outside of class time.
Students set weekly goals via Google Forms every Monday and reflect on if they meet these goals at the end of each week. This is a reflective process where students are asked questions that allow them to understand what factors contribute to their success or failure in the class. It also gives me a document I can refer to if I see students are consistently not meeting their own goals.
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.
