Integrating STEM (science, technology, engineering, and mathematics) in authentic ways is often overlooked in early childhood spaces, despite young children having the ability to engage with the world around them through STEM practices. This piece showcases the work of children in a prekindergarten classroom as they explored an integrated STEM…

This article describes the author's experience designing and implementing an inquiry-based learning (IBL) pedagogical approach to an upper-division undergraduate cryptology course. The author shares the course goals and how the IBL style supports their achievement. The article concludes with sample activities -- in-class exercises that touch on…

This paper is a practical how-to guide to help you start using active learning or to have greater success and more fun with it. We categorize active learning techniques as Think, Pair, Share, Composite, Group, Move, or Lead and discuss how to implement activities in each category, along with advice on creating engaging, effective, and equitable…

In this paper, we discuss mathematical modeling opportunities that can be included in an introductory Differential Equations course. In particular, we focus on the development of and extensions to the single salty tank model. Typically, salty tank models are included in course materials with matter-of-fact explanations. These explanations miss the…

Rapid advancements in bioengineering call for broad public literacy to help individuals better understand the changes these technologies bring to our lives. However, making bioengineering concepts accessible and relevant, especially to non-science majors, is often challenging. To address this challenge, we designed a general education course aimed…

The mathematical egg hunt is a hands-on activity designed to help students understand mathematical relations in an Introduction to Proofs course. This activity gives students the opportunity to practice selecting which ordered pairs do and do not belong to a given relation in a moderately competitive egg hunt. It is designed to be low-stakes, yet…

In this article, we present an intriguing experimental exercise that does not fall foul of improper use of instrumentation. The activity is designed as an electronics exercise where the role of the instruments in the measurement of the RC time constant is considered. Essentially, we study the accuracy and precision of a measurement of the RC time…

The 17 United Nations Sustainable Development Goals (SDGs) employ a global indicator framework to detail each Goal and monitor its implementation. This article focuses on three targets from the indicator framework, which call for mainstreaming education for "global citizenship," "sustainable development," and "climate…

Syntheses of analogues of historical indigo and Maya blue pigments using an inquiry-based approach are presented. Derivatives of indigo were synthesized (in particular Tyrian purple) and used as vat dyes for dyeing cotton or wool fabrics or mixed with a sepiolite clay to create new hues or colors of Maya blues using a green chemistry hydrothermal…

A cancer diagnosis enlivens the question of what it means to live well with the Earth and its multidimensional beings, including the children I teach. A cancer diagnosis provides a necessary push to step out from the confines of a self and toward and into the wild fray of this life. I interpret my lived experiences through the practical philosophy…

Little is available in mathematics education research about what the teacher can anticipate from the students when applying inquiry-based learning (IBL). Even less is known about how to recognize and exploit on the spot when a mathematical domain, other than the one in focus, is activated in the students' minds. Yet, in tests, in everyday life,…

In "Uprooting Instructional Inequity," noted leadership coach Jill Harrison Berg offers a comprehensive guide to help school and teacher leaders amplify the power of collaborative inquiry as a means for identifying, interrogating, and addressing instructional inequity. At the center of the book is Berg's i3PD Planning Map, an invaluable…

Inquiry is the essence of social studies, and inquiry "looping" in social studies curricula means offering students opportunities to engage in inquiry in regular intervals and in a coherent fashion within and across grade levels. This can benefit the youngest students since they are filled with hope and want to make a difference in the…

We present a classroom exercise developed to teach the tools of determining order quantities and reorder points for inventory management. This exercise presents the students with an inventory management scenario but only provides a portion of the data that are required to set order quantities and reorder points. The activity is a type of…

By some estimates, over 1.2 billion tons of soil was blown across the Great Plains during the height of the Dust Bowl. The so-called "black blizzards" these massive dust storms caused suffocated cattle, sickened children, and destroyed thousands of family farms. Formerly prosperous farmers, unsure why they had such bad luck, wondered if…
