Episode 131: Our Hiatus Explained (no excuses, but we’ve been a little busy this spring…) 13.05.2026 25:17
Our semester-long hiatus is over! We’ve missed you, friends, and we wanted to check in this spring.

Abby and Dave start off this conversation reconnecting after a week of not seeing each other, because we were both presenting at different Christian education conferences. After a little catching up and reconnecting, we shift to our main topic: parent teacher conferences. (‘Tis the season!) We share stories of our own experiences as young teachers, learning how to lead a parent-teacher conference,...
Episode 126: Re-energizing in the Middle of the Semester (or, “the honeymoon is over, and it’s time to mix things up!”) 22.10.2025 18:59
We are in a season of transition! It’s been a wonderful journey as a trio, but with changing demands, Matt is going to step away from the podcast. We are grateful for the time and conversations we’ve had over the past four and a half years(!) and we wish him well as he moves into other adventures. Abby and Dave have decided to continue to record new episodes, and we hope you’ll continue to join us...

After a summer away, it sure felt good to get back together in front of our microphones. This first episode for season 10 is really just catching up on all the things we’ve been doing since we last recorded in May, and sharing about all the cool stuff we have coming up in the next couple of months as well. We’re excited to be back with you, friends, and we hope and pray that our hallway conversati...

We are at the end of another semester, and at the end of another season of this podcast adventure. In this episode, we reflect together on our practices, on the things we are taking away from this year, the nature of teaching as “planting seeds,” and the importance of Sabbath for educators. We hope that this conversation encourages you all to wrap up your own academic years well, friends. With thi...
Bonus: More Great Ideas with Erik Ringsby 09.05.2025 8:49
After recording our last episode, we left the microphones running as we sometimes do, and had another amazing interaction full of wisdom from our pal, Erik Ringsby.

Hallway Conversations is sponsored by the Center for the Advancement of Christian Education. You can learn...

Episode 122: Finding Joy Amidst Frustration (or, Dave adopted a dog and is navigating this!) 09.04.2025 30:19
This episode was prompted by an email Dave sent to the rest of the crew–we’ll let you listen to hear the details–but it has to do with finding lots of joy amidst some frustration. This got us thinking about the nature of joy, and we share some of the joyful memories we have from our growing up years as we begin. Then we shift to talking about finding joy in the work of teaching, even when it is ch...

In this episode we have the opportunity to interview our new friend, Shaun Brooker, who serves as Head of School at Hamilton Christian School in Hamilton, New Zealand. It was a pleasure to meet Shaun in person at the recent Converge conference in Orlando, and we were delighted that Shaun was able to join us for the show, despite the time difference between the Waikato region in New Zealand and Nor...
Bonus Episode: It's Good to Be Smart! 19.03.2025 9:16
Friends, we know it’s been a bit since we’ve had a new episode. Never fear! We have more fun ideas still to come this spring, including some great interviews. In the meantime, we’d like to share Dave’s side project: another podcast! This one is a STEM-oriented podcast supported by a grant from the National Science Foundation called It’s Good to Be Smart! The idea is that science teachers (grades 5...
Episode 120: Accountability and Trust (a conversation with Darryl De Boer) 19.02.2025 36:27
Matt noticed that it was four years ago last week that we started this podcast adventure–and what a wonderful time it’s been for us! We’re so grateful to you all, dear listeners, for joining us on this journey. We hope it will continue to be a blessing for you. In honor of that milestone, we start things off with some reflections on what we have learned and what we love about this project. This we...
Episode 119: Teacher Collaboration (or, why Abby thinks co-teaching is a fantastic idea and we should do more of it!) 05.02.2025 22:48
In this episode we think about whether teaching is best pursued as a solo project, or whether it makes more sense in this day and age to look for ways teachers can collaborate in the work of teaching. We share some stories of our own experiences–in higher ed, and in our K-12 teaching–where we tried co-teaching. We explore the benefits and drawbacks, and try to paint a realistic picture of what a s...

Welcome to a crossover episode with our good friend, Dr. Justin Bailey, who hosts the In All Things podcast.

Justin, Abby, and Matt ask Dave about his motivations for writing the book, the content, the approach, and r...
Episode 117: Christmas Gifts! (or, Dave got a rubber duckie from a student, and he’s an idealist) 18.12.2024 23:11
Christmas time is here! (Cue the “Merry Christmas, Charlie Brown!” music!) It’s the end of the semester, and we take a little time to reflect on what we’ve done and what we’ve learned this semester. Matt prompts the discussion this week with a two-part question: 1) What gifts did we receive from our students this year? And 2) What gifts would we like to give to educators? We have a lot of great th...
Episode 116: So Many Things! (or, what happens when we don’t actually plan a topic and just talk in front of our microphones) 04.12.2024 26:27
For those who have been with us from the beginning, you might remember how this podcast started with just Matt and Dave, and how we didn’t tell each other the question we were going to bring in, and just stumbled our way through thinking on our feet about how we might answer that question. We are recapturing a bit of that feeling in this episode! We sat down at our microphones at our normally-sche...
Episode 115: Being a Real Human Being (or, why Dave should not teach when he isn't feeling well) 20.11.2024 31:00
In this episode we start off with some random check-in questions from Matt, inviting us to share some things about ourselves. (Be ready for some silliness, dear listeners!) This leads us into Dave sharing a story about teaching while not feeling well…and how he nearly passed out in class. The question Dave raises: how much should we let students see us as “real human beings?” We talk through vario...
Episode 114: What Should We Do about AI in Education? (or, Matt has a lot of questions, and Abby and Dave have ideas) 06.11.2024 34:45
We start off this episode sharing about the different things we’ve been doing lately, with different conferences where we’ve been presenting lately. (It was marvelous for Abby and Matt to meet up with many listeners at CEA!) Dave’s conference actually sparked the topic for this week’s conversation: so many of the sessions at his EdTech conference dealt with AI in Education. We have questions, and...
Episode 113: Why Aren’t People Becoming Teachers? (or, why Dave thinks we have to elevate the profession!) 23.10.2024 25:38
This week we start off with a rant about Christmas decorations already being out in the stores (it’s only the middle of October!) which turned into a just-for-fun check-in question about our favorite Halloween treats from our youth. The heart of our conversation today stemmed from an impromptu conversation Matt had with a campus visitor about the Education profession, and the prospective student w...
Episode 112: Connections (or..."We're Back, Baby!") 09.10.2024 28:40
We’re (finally!) back in the studio (okay, Abby’s office with a creaky table) to record again. We’ve missed this so much! We start by catching up about some of the events of our summer, and the things we have upcoming–lots of opportunities for us to meet up with Christian educators in different places. We love connecting with colleagues across North America, and around the world! And along these l...
Episode 111: What Have We Learned? (or, why Dave believes “the people are the work!”) 22.05.2024 18:24
Our final episode for this season–a little time to reflect on Matt’s question, “What does it look like to end well?” We shared some of the joys and sorrows we feel at the end of a term, ideas for how to end well, and some of the things we deeply believe about the rhythms of the school year. We also took some time to look back over this year and name some of the things we have learned. We recognize...
