What is Reasoning?

I attended a professional development session on the NGSS earlier this week by Brett Moulding and Nicole Paulson based on the book they wrote with Rodger Bybee, A Vision and Plan for Science Teaching and Learning. The authors propose the “gathering-reasoning-communicating” (GRC) structure as a simplified way of thinking about the Science and Engineering Practices. Reasoning is the keystone of the GRC structure and the primary thing we want science students to be doing. “Gathering” provides the raw materials for reasoning and “communicating” helps us know that reasoning has taken place.

Break the Ice with Mystery Blocks

In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.

Disappearing X Lab

In the embedded video, I will walk you through a kinetics experiment we use in our Chemistry 2 (and Honors Chemistry 2) courses. The lab is called Disappearing X.

Building a Blended Culture in a Secondary Science Classroom

During my first year of teaching (in Indianapolis, IN), I was inspired by some research I had read as well as some other teachers in the Indy area who were flipping their classes. I was at a small parochial school where parental and administrative support for technology inclusion was present. My principal outfitted me with the tools I needed to “flip” my classes and record tutorial videos. Things went pretty well. It was a learning curve for many but I also had good feedback from students and parents.

Accepting Our Role in Developing Science Literacy

Though we may recognize its presence, teachers, scientists, and policymakers still disagree on the most practical and effective methods for developing scientific literacy in our students. Herein lies our challenge as science educators—what can we do in the classroom to create experiences for our students that involve the understanding and appreciation of the most valuable traits associated with being scientifically literate? This article includes resources and a sample assignment that will hopefully get all of us off on a good start.
