Quick Quizzes
When we are asked seemingly simple questions but are held accountable for why we have particular views, we are forced to evaluate our thinking, assess what confidence we have and why we have it, and support our claims while engaging in dialogue with appropriately skeptical peers. Quick Quizzes (QQs) are carefully designed problems that allow teachers to easily engage their students in authentic discourse. Due to their ease of implementation, and because active engagement, metacognition, and discourse all support student learning, QQs are a great tool for teachers to implement even if they are forced to stick to a strict curriculum.
Not sure where to start? Take a look at some of our favorite examples in the gallery below! To minimize barriers to entry, we focus on systems that require minimal prep time and use mostly readily available materials. In cases where the system is costly, custom made, or dangerous, we encourage you to simply play the video in your classroom, pausing to allow students to engage with one another. A new quiz will be uploaded to our YouTube every Monday and Friday, so be sure to subscribe and set up notifications!
Notes on Implementation
We have tried to organize QQs by topic and put them roughly in the order they would appear in a traditional introductory physics sequence. Within each unit, we also order them in one suggested sequence; however, teachers are encouraged to stray from this as they see fit. To ease implementation and the writing of lesson plans, we also include materials needed, student difficulty (beginner, intermediate, difficult), and alignment with the Next Generation Science Standards (NGSS).
