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.
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.
Planning is an essential part of a blended teacher’s practice. In blended environments, where students can be at different points in a course on various modalities, blended teachers need to be very intentional about how they plan. Check out the video below to see how Jeff plans for instruction in his blended classroom.
Assessment and data play a crucial role in a blended teacher’s classroom. Blended learning gives teachers an opportunity to assess consistently throughout a class, in a way that drives instruction, impacts grouping, and assignments. Blended educators have to develop capacity to sift through multiple sources of data and synthesizes quickly into action. Check out how Ben utilizes Assessment and Data here.
