Talking about learning goals: does a hierarchy imply a value judgement? Why do we need to name learning objectives anyway?

7. Screen Time, with Bethany Corrie 01.04.2026 47min

If you spend time with young children, invariably you will at some point get into conversations about screen time-- the detriments, maybe some benefits, and definitely some judgements, no matter where you land. In this episode, Bethany and I discuss our own experiences with digital media as educators and parents, and some perhaps surprising information that may influence how we're looking at the harms of screen time.

6. Coloring Pages, Part 2, with Tiffany Pearsall 13.03.2026 43min

We're back with Tiffany Pearsall! In part one, we talked about creativity; but a lot of the information out there is really about coloring pages and mental health. Where does using this research fit in with ethical practice in early childhood settings? What are our responsibilities and professional scope of practice? And of course, where do coloring pages fit in a setting that wants to offer children the opportunity to create freely?

5. A New Vision for a High Quality Preschool Curriculum with Dr. Denisha Jones 27.02.2026 40min

Dr. Denisha Jones, of Defending the Early Years (DEY) and I discuss the 2024 publication from the National Academy of Sciences, Engineering, and Medicine called A New Vision for High-Quality Preschool Curriculum; in particular, we look at Chapter 4: Developing High-Quality, Equitable Preschool Curricula, and discuss what real commitment to equitable education looks like, and who should be developing the curriculum for it. Hint: page 129 of this report says, "Curriculum development requires broad and deep knowledge, experience, and expertise. Therefore, it is important to ask who develops curricula for preschool currently and who would ideally. Preschool teachers cannot be expected to create curriculum resources independently (Ball & Cohen, 1996; National Academies, 2020, 2022); in addition to expertise, the task requires substantial time and teamwork." We disagree. National Academies of Sciences, Engineering, and Medicine. 2024. A New Visionfor High-Quality Preschool Curriculum.

4. No Benefit to Group Care Prior to Age 3? with Heather Bernt-Santy 13.02.2026 37min

In the enormous child care care ecosystem conversation, there is an idea that one to one care, like a nanny, parent, or grandparent, is ideal until a child is three years old, at which point they are able to "benefit" from being in a group with other children. We look at this claim, the idea that group care is either not beneficial or actively detrimental, and talk about what quality of care really comes down to.

3. Coloring Pages and Creativity, with Tiffany Pearsall 05.02.2026 38min

While there isn't often a hard and fast rule, coloring pages are often looked at as "busy work" or as having no place in a child led classroom, with beliefs about the potential for negative impact on children's creativity and discovery. Why would a child want to learn to draw independently if we have pages already made with all of the pictures they could want to draw! Surprisingly, there's very limited research on coloring pages and their impact on creativity... or anything else for young children.

1. Critical vs. Radical Scholarship 02.01.2026 50min

Before we talk about specific research in early childhood, I wanted to talk about the history of the institution of science-- how it has served to both expand human knowledge and block out those it has deemed "unfit" to be in its halls, how unintentional bias and purposeful bigotry have made and maintained their way in, and how modern scholars can work to expand the canon of what we know and how we know it. Lizz talks with Dr. Bee, a professor of sociology, about bias, science, and what it means to be a radical scholar.
