Reactions to CMC South:

A few weekends ago I spent the better part of two days wandering about the California Math Council’s Southern regional conference at Palm Springs. I just thought I would reflect on some of what I saw, heard, and learned.

CMC South

The bulk of my time was spent at sessions related to Transformation Geometry (TG). This is a topic at the center of my own doctoral work and so I have a keen interest in what others are saying about it. This is perhaps one of the most profound and new inclusions to the math curriculum I have seen in my nearly 30 years as a professional in math education. This is because it represents a shifting of perspective, or basis for understanding core ideas in Geometry. It is exciting to see this shift happening. Starting from a TG viewpoint we can create testable definitions of congruence and build a base understanding that is vertically articulate through higher studies. My next post will be on this topic.

While focusing on TG was a personal goal, I also took time to head to a few of the more broad-based presentations as well. Robert Kaplinsky and Jo Boaler are two members of the math-teaching world that are changing the face of math education today and for the future. If you get a chance to read anything by either, I highly recommend it. Jo Boaler provided me with my favorite quote of the conference, “Questions with one right answer promote a ‘Fixed’ mindset; open up your questions if you want to encourage a ‘Growth’ mindset.” This refers to some very important findings by another critical figure in today’s math education world, Carol Dweck, who has found that what can be identified as a fixed mindset towards math ability has an affect of limiting achievement in students.

The interplay of strong thinkers and excellent teachers is what keeps us at the Center excited and interested in our work.

What Unit is the Child Counting? – Motor Units – Part One

In my previous blog I wrote about the characteristics of perceptual and figural counters, which are two of five counting stages Leslie Steffe, Ph.D. identified through his research. Simply covering counters can be a powerful way to encourage students’ development of abstract units. In this blog we will look at counters of motor units. Counters… Continue Reading

The Right Professional Development for Smooth A Transition To NGSS

Are you gearing up for Next Generation Science Standards? I want to share a few facts about what the NGSS expectations will be for educators. It is my hope that the following helps you to start thinking about a Professional Development plan to make the transition smooth for teachers and students. There are areas of… Continue Reading

What Does a Tree Eat? Part Three

The one point that science education researchers agree on is that human beings, almost from birth, learn how to live in the real world dominated by forces and motions. Humans learn to crawl, stand, walk, and run without instruction. They know that running into a wall hurts much more than walking into a wall. As… Continue Reading

What Does a Tree Eat? Part Two

I reported in my previous post that seventh graders, in three science classes, believed that a tree grows by eating dirt. Historically, that is exactly the belief held up to the Middle Ages. In 1634 the Belgian Jean Baptist van Helmont performed what may be the first experiment on plant growth. He too hypothesized that a… Continue Reading

How I See the Change at AIMS Affecting the Graduate Math & Science Education Program at FPU. – Part Two

Since AIMS grew out of efforts by FPU faculty in the 1980s the two entities have been closely tied together. This will remain the same in the future, in fact even more closely linked than ever before. All the professors in GMSFPU will also be spending time at the Center. And with the focus of… Continue Reading

What Unit is the Child Counting?-Perceptual and Figural Unit Items

What Unit is the Child Counting?-Perceptual and Figural Unit Items

In my last blog I talked about some of Dr. Leslie Steffe’s research and how he observed fractional understanding develop in children through counting and their understanding of number. He has articulated the following five stages of counting types in his book Children’s Counting Types: These stages are important in a child’s ability to work… Continue Reading

Professional Development in an Education World of Accountability

The AIMS Center for Math and Science Education is prepared to help. We are available to collaborate and build an effective Professional Development Plan for your school or district. We know that educators benefit from good sustained professional development and in today’s high stakes era of standards and student achievement it is usually focused on… Continue Reading

What Does a Tree Eat?

One of the failings that science education researchers generally agree on is that our science instruction does not begin with an attempt to find out what students know, and therefore what they really believe about a science topic, before we teach it. Photosynthesis, the process used by plants to convert light energy into chemical energy… Continue Reading

Learning What Steffe’s Research Found Supports Fractional Knowledge

I have always been passionate about how children learn and equipping teachers with the tools that would empower them to be more effective teachers. So, when the opportunity to work at The AIMS Center for Math and Science Education at Fresno Pacific University became available, I enthusiastically applied. As a research associate at The AIMS… Continue Reading
