In this chapter, the author provides an example of an integrated and collaborative activity for in-service mathematics teachers that was implemented synchronously online. While prior research details how this lesson developed middle and secondary teachers' mathematics content knowledge of logarithms and teachers' science content knowledge concept of pH, this chapter focuses on how the lesson was converted from a face-to-face format to the online format while supporting research-based essential teaching skills, specifically NCTM's Mathematics Teaching Practices (MTPs). Evidence is provided for how three MTPs were upheld using the online platform Blackboard Collaborate, followed by recommendations for other teacher educators wishing to engage teachers in online learning that supports mathematics education goals of integrated STEM education through mathematical discourse, conceptual understanding, and reasoning about mathematical representations.
