For today’s “Texts on Tuesdays”, I thought I would share some resources that you might be interested in if you ARE wanting to learn more about how children learn to solve problems.

What is CGI?

Cognitively Guided Instruction is an approach to teaching math developed at the University of Wisconsin in the late 1980’s and early 1990’s (yes, this is when I was there!).  It is based on using students’ own thinking as the foundation for instruction…in other words, teachers base what THEY do off what the students already know.  The researchers (Carpenter, Fennema, and more) base their work on the assumption that students come to school with a certain amount of informal understanding about numbers and math.  The teacher’s job is to learn what students know already, build upon it, and help students make connections between real-world math “stories”/experiences and–eventually–the abstract symbols we use to represent math (like +, =, etc).

This is VERY different than how math is traditional taught where we start very early by teaching the abstract symbol (“+) and then try to attach meaning to it.  In other words…we need to teach math IN a REAL WORLD CONTEXT well before we introduce those abstract symbols!  By immersing students in story problems from the day they enter our schools, we can better help them understand math and help them to be better problem solvers with better number sense.  The implications for us as teachers is that we need to become experts in “reading” our students, learning what they know (see why mathematical discourse will be so important?!?), and then making smart educational decisions for them.

As teachers we must also learn about the different processes and strategies that are typically used by children to solve these problems, and the various stages that students go through as they develop their math knowledge.

Ok…I know this was wordy and I STILL didn’t convey the essence of CGI…if you are intrigued, I am including links to a few articles that you may find interesting!  I seriously wish I could convey it better…but if you are intrigued, I hope you might find some of these resources interesting.

I love this book…if you really want to learn more about CGI, I think this is the book to get.  It’s a little pricy, but on Amazon I did see used ones for about $10!  I put the link below so you can check it out…this is an affiliate link that will take you right to Amazon.

So…CGI is really critical in the early years…but for ME, as a fourth grade teacher, I feel I need to backtrack with some of my strugglers to give them some of these experiences.  I worked to organize my thoughts and created some problems to create an “intervention” group of sorts…and as I kept going, it grew and grew.  I wanted sets of word problems that were “real world”…I wanted students to be able to select “just right” numbers to use–so different levels could use the same problems…I wanted BIG sized problems to use for teaching.  THIS was born!
