Correctional Assignments provide another layer of practice for my students who fail a quiz before re-attempting to master the topic. The process is simple - my students complete the Correctional Assignment and then re-take the mastery quiz. My students can follow this process as many times as needed until they pass the quiz and achieve mastery. For this reason, I use IXL.com and Kuta Software for Correctional Assignments, which both generate infinite sets of practice problems.
At the beginning of each trimester students are given a checklist to track their own mastery. As they progress through the lessons, they mark off what they have completed, in addition to the grade they received on each lesson. This acts as planner, letting students know at any given moment what they have completed, and what is left for them to learn to finish the trimester.
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.
Many students fall behind the class pace as the school year progresses, so I build in time to the class schedule for students to catch up. Before or after a break or towards the end of a trimester I won't move the lesson pace forward, giving students the opportunity to get back on pace.
