This past summer our conversations turned to, “How can we improve our instruction to try and prevent the initial misunderstanding?” We had all read Dorothy Gabel’s article Improving Teaching and Learning Through Chemistry Education Research: A Look to the Future. We were intrigued by the author's description of the three fold system of representing concepts in chemistry.
Using a whiteboard or poster paper each group of students creates their interpretation of the model thus far based on a content unit they are given.
The American Modeling Teachers Association (AMTA) website is the official source for information on Modeling InstructionTM (MI). Whether you are an experienced Modeler or simply interested in learning more about MI, I encourage you to visit the newly redesigned site and check out the available resources.
I started thinking about how integral the storytelling was to the curricular choices I made in my classroom. I realized that I had shared some of my experiences as a Modeler and a few of the activities we use in our classrooms, but I have never described the order of topics. So, this blog is titled “The Model So Far…” I hope it gives you an idea of the journey we take each year as the students uncover evidence and construct models along the way.
This is a Chemical Reactions lab that I modified to meet NGSS guidelines.
Through a series of three blog posts, I’d like to share my thoughts about these scientific practices and how we might communicate about these practices to middle and high school students. I’d love to hear your thoughts along the way! Let’s start with model building…
From the misconceptions fostered by the biology textbooks using the phrase “high-energy phosphate bond” to idea that energy comes in different forms, the Modeling community recognizes the challenges of teaching the energy concept and has developed a way of talking about energy designed to help students construct a consistent and cohesive model.
This lab was written as part of the Target Inquiry program at Grand Valley State University in Michigan. Students build an electrochemical cell, learn about the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process.
