The Demo Discussion is a strategy I use to provide an interesting and memorable in-class demonstration of complex concepts that my students will learn about in class on a given day, using a variety of digital resources. The Demo Discussion is an excellent way to promote student curiosity about scientific phenomena. The "demos" provide access points for my students to witness and wonder about complicated chemical processes that they will eventually explore and understand at a much deeper level. By leveraging additional physical and digital tools, I can facilitate in-depth analysis and support the development of models to explain the science behind the demo. This strategy also allows me to surface my students' questions and interests about the day's Learning Targets (please see the "Learning Targets" strategy video), to which I can refer and make connections throughout our exploration of that content.
I would describe my classroom model as a tweak on a flex model of instruction. I start each class period by giving students a problem I want them to solve, such as “How would you use the gas laws to explain how popcorn pops?” Students then have the opportunity to create their own learning paths by accessing a variety of curated online and offline resources and activities. I determine if a student has achieved mastery on a given concept by evaluating the online and offline work products they have produced during class and by administering more traditional assessments. However, if a student fails an assessment, he or she can always go back and re-take it. My classroom is 1:1 with a mix of MacBooks and iPads, which have become the vehicle for my students to move at their own pace through difficult chemistry content.

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.
The most common answer I give students when they ask me a question is "look at your notes." The course is designed so any question in the practice problems or mastery quiz have been directly addressed on the current video lesson or a past one. Because the design of the lessons has been created with this intentionality, it's easy to refer students to the exact place in the notes they can find their answer. It's been a challenge to not jump in and immediately offer students help, and many get frustrated in the moment, but over the course of the year students develop strong independence in their learning, able to use their notes, peers, and online resources to find the answer they were looking for.
