Northwest Ohio Center for Excellence Symposium on STEM Teaching

Conjecturing adds up to better learning, BGSU prof Gabriel Matney tells STEM teachers

By DAVID DUPONT BG Independent News One may have assumed a talk entitled “The Power and Promise of Developing a Conjecturing Modality” would be a bit on the dry side. The speaker, Gabriel Matney, an associate professor of math education at Bowling Green State University, would advise that rather than assume one should make a conjecture that the talk could instead be engaging and enlightening for the 300 or so teachers and students of mathematics in attendance at his keynote address for the Northwest Ohio Center for Excellence Symposium on STEM Teaching two weeks ago. “Rather than assuming that we know and acting on it,” he said. It’s better to engage in “conjecturing and testing those conjectures and see if they hold or not.” Could this talk be inspiring? Yes. Matney explained how he made a conjecture as a teenager in love. He was dating this girl, and he conjectured that even though he could barely afford a car for himself, he could one day get her the car of her dreams. So he asked her to describe her dream car. She detailed a purple, tricked-out Dodge Stealth. So 19 years later that girlfriend, now his wife, got that car. It did take a few years extra because it had to be specially painted purple. When delivered it was “an epic Valentine gift” born of early planning. Conjecturing, Matney said, as powerful teaching and life tool. Matney rooted his talk in his own life. He had the audience tackle problems that he had originally posed to his three daughters, now teenagers, when they grew up. He conjectured, he said, that “if I spoke academic language instead of common parlance, they’d be able to handle academic language.” So as a preschooler, his eldest child would spot a box and know it was a “rectangular prism,” even if she couldn’t quite get her tongue around all the syllables. A trip to the bank with his second daughter resulted in a lesson in negative numbers. She persistently questioned him about why they were there. Matney explained to her that if they wanted to make “expenditures” they needed to deposit money so they didn’t go into negative numbers. And he posed a challenge to the audience, to recreate a shape that was flashed onto the screen with blocks piled in the middle of their tables. He noted that when he did this with his three daughters, it was the youngest, still a preschooler, who always got it right. She would put it together and ask: “Is this it?” She did not assume she had the answer, rather she posited what she came up with as a possible solution. Matney recalled working for his step-father’s lawn care business. Getting from customer to customer was a challenge, given distances and traffic. This was in the days before GPS, so Matney sat with a map and carefully planned out the route taking into consideration traffic patterns. “Taking time to think about it saved us days of life.” When he became a teacher. conjecture took a central role in his lesson plans. Matney got a job in an inner city school in Oklahoma City. Half the violent crimes in the state took place in the school’s neighborhood, which was plagued with gangs. The students came into ninth grade…

Registration now open for STEM teaching symposium at BGSU

From BGSU OFFICE OF MARKETING & COMMUNICATIONS Registration is now open for the annual Symposium on STEM teaching, which will be held Nov. 18 at Bowling Green State University. With nearly 50 informative and engaging sessions encompassed in six different STEM teaching and learning strands, the annual Northwest Ohio Center for Excellence Symposium on STEM Teaching offers a valuable opportunity for in-service and pre-service teachers, higher education faculty, and business and community partners to share and learn from one another in a common effort to advance STEM education for people of all ages. BGSU faculty member Gabriel Matney will be the keynote speaker. A former middle and high school teacher, Matney holds a Ph.D. in Mathematics Education and is in his sixth year as an associate professor of mathematics education in the BGSU School of Teaching and Learning. Matney has actively worked on numerous grant projects designed to help in-service teachers create dynamic and minds-on classrooms that improve the learning of their students. His research centers on improving professional development for teachers and the development of pre-service teachers as professionals. In addition to his work with teachers in northwest Ohio, he has given more than 74 workshops across the United States, Thailand, South Korea and Japan. The pre-registration and onsite registration fee for the symposium, which runs from 8:45 a.m. to 3 p.m., is $40. The fee for undergraduate and graduate students is $5. The registration fee includes six hours of high-quality professional development, the keynote address, conference bag/materials and lunch.
