Brian Lemmen


Brian Lemmen has been teaching high school mathematics for 31 years. He currently is teaching at Holland (MI) Christian High School, a six-year recipient of the Apple Distinguished Program Award. Brian received his BA degree in mathematics in 1983 from Calvin College and his MA from California State University at Fullerton in 1991. He has been involved with the Core-Plus Mathematics Project (CPMP) since 1996 when Holland Christian High School first adopted CPMP. This involvement included being a field-test teacher for the 2nd edition of Core-Plus Mathematics and a professional development facilitator for multi-day workshops for new adopters across the country. More recently, Brian was a field-test teacher for the NSF-funded Transition to College Mathematics and Statistics (TCMS) course. As a field-test teacher he has provided extensive input and feedback to the development of the CPMP-Tools and TCMS-Tools software. Most recently, Brian partnered with AJ Edson, a Ph.D. candidate at Western Michigan University, in testing a prototype deeply digital unit on Binomial Distributions and Statistical Inference.

Presentation Title:

Deeply Digital Curriculum for Deeply Digital Students

Presentation Description:

As educators we dream of students collaborating on the solution of authentic mathematical problems and constructing viable arguments while critiquing those of others. Because students live in a technological world, we as educators need to meet students where they are. Using an evolving prototype of a deeply digital instructional unit I was able to do just that during the last two school years. As a panelist, I will elaborate some of the affordances of this set of digital materials. I will also discuss how this deeply digital unit affected what and how my students learned. Additionally, I will discuss how the experience affected my role as their teacher. Finally, I will share how implementation of the digital unit affected how my students and I interacted in and outside the classroom.
