How can Leaders Support Schoolwide Direct Instruction? with Bonnie Grossen and Kurt Engelmann
Hello everyone, and welcome back to the Direct Instruction Podcast. I’m Dr. Zach Groshell, and today I’m joined by two outstanding leaders in the DI community: Bonnie Grossen and Kurt Engelmann.
Bonnie Grossen has supported schoolwide Direct Instruction implementations across a wide range of settings—from urban districts to rural communities, both in the U.S. and internationally. In this episode, she shares key lessons from supporting Direct Instruction at the Arthur Academy Charter Schools.
We’re also joined by Kurt Engelmann, returning from Episode 1, who brings sharp insights into the real-world execution of Direct Instruction.
Together, Bonnie and Kurt walk us through what full-immersion, schoolwide DI really looks like. We explore how the model originated, how it adapts across grade levels, how it aligns with Multi-Tiered Systems of Support (MTSS), and the critical role of leadership in sustaining success. We also talk about realistic expectations and the most common mistakes schools and districts make when implementing DI.
This podcast is brought to you by NIFDI, the National Institute for Direct Instruction. NIFDI partners with schools around the world to support high-fidelity DI implementation. I’ll be bringing this podcast to their annual conference in Eugene, Oregon, summer 2025—and I hope to see you there! Visit www.nifdi.org for details.

My name is Dr. Zach Groshell, and today I am excited to be bringing you a glimpse into my classroom for an unscripted coaching session with Tamara Bressi.

This episode is structured so that you first hear a recording of me teaching prior to receiving any training, followed by some feedback from Tamara. Then, we will listen to a “post-training” recording, where Tamara and I discuss some of the shifts I have made in implementing Direct Instruction with greater precision.This episode is brought to you by NIFDI, or the National Institute for Direct Instruction.

How Has DI Impacted Reading Proficiency in Indigenous Communities? with Casey Sovo
Hello, and welcome back to the Direct Instruction podcast. My name is Dr. Zach Groshell, and today I am excited to be bringing you a fantastic episode about the role of Direct Instruction in teaching kids to read in indigenous communities across America. I will be interviewing Casey Sovo, a member of the Comanche Nation, a 20-year educator, and a Bureau of Indian Education program administrator. Casey will speak to the incredible improvements in performance of schools that he supported when DI was implemented with fidelity, as well as the obstacles or barriers that he had to address when implementing DI. We will also talk about the times when DI was discontinued in the schools he supported, the dramatic dip in performance that followed, and the return to positive growth when schools decided to restart with DI. Overall, I was inspired by Casey’s passion to eliminate the achievement gap for indigenous students through a data-informed, all-hands-on-deck approach to teaching reading, and it was an honor to have him on the Direct Instruction podcast.
This episode is brought to you by NIFDI, or the The National Institute for Direct Instruction. Registration is open for the National Direct Instruction Conference in Eugene, Oregon this summer, where, in 2024 when this episode was published, Casey Sovo will be the keynote speaker!

What is Direct Instruction Mathematics? with Marcy Stein and Bernadette Kelly
Welcome back to the Direct Instruction podcast, my name Dr. Zach Groshell, and today we are going to be talking all about Direct Instruction Mathematics.
What you just listened to comes from a 1966 video recording of Zig Engelmann, which I have embedded in the show notes. If you’re not driving while you’re listening to this, I highly recommend that you pause this podcast right now and watch the video in full. It is a perfect showcase for how rigorous and well-structured instruction can empower young learners to grasp even the most complex mathematical concepts.
But what is Direct Instruction mathematics, and how does it differ from more conventional ways of teaching of math? To answer that question, I thought I’d interview some of the experts of DI math about what goes into the design and delivery of this highly effective teaching system. Dr. Marcy Stein is the lead author of Direct Instruction Mathematics and Professor Emeritus of The University of Washington Tacoma. Also joining us is Dr. Bernadette Kelly who co-authored the DI programs, Connecting Math Concepts and Essentials for Algebra. This is an incredible episode that I hope will prompt more schools to consider how top-notch materials designed with the DI approach can break the cycle of stagnant achievement in mathematics.This episode is brought to you by NIFDI, or the The National Institute for Direct Instruction. Registration is open for the National Direct Instruction Conference in Eugene, Oregon this summer. Whether you are new to Direct Instruction, or are looking for training on Administrative Leadership, Coaching, and Becoming an Effective DI Trainer, this is the conference for you. I’ve provided the links to register in the show notes, and I encourage you to sign up for what is the most comprehensive DI training available anywhere.
