Inquiry-based learning (IBL) refers to any pedagogy that utilizes presentations or student-centered activities to develop in students the confidence and ability to do mathematics on their own. JIBLM

SIMIODE is steeped in an inquiry-oriented mentality!
My involvement began with a highly effective Summer 2015 MAA PREP Workshop: "Building Community in SIMIODE - Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations" in Helena, MT. I have enthusiastically embraced SIMIODE, which led to the NSF grant that includes hosting faculty workshops; Board of Contributing Advisors; multiple conference presentations; multiple co-led MAA minicourses at national conferences; SIMIODE Challenge Using Differential Equations Modeling (SCUDEM); and more.

For 2012-2016, I had great support by SU's HHMI funded Natural Sciences Inquiry Initiative under Dr. Emily Niemeyer and others. I presented a workshop to share modules I created at our culminating conference June 1-3, 2016. "Transforming STEM Pedagogy Through Active Learning"

I participated in the mini-conference Constructing the Future of Inquiry-Based Learning (IBL) Conference: The Past 20 Years and the Next 20 Years on July 27, 2017 in Chicago, IL.

Expanding IBL Throughout Higher Ed in Columbus, OH, Aug 4, 2016. An extension of the Legacy of R. L. Moore Conference on Inquiry-Based Learning offered by the Educational Advancement Foundation.

I was a TIMES Scholar for Fall 2015 in IODE or Inquiry Oriented Differential Equations, under Dr. Karen Keene from North Carolina State University, on the NSCU NSF grant she has with other collaborators. I participated in a summer 2015 IODE workshop, and I was a TIMES Scholar for Spring 2015: Teaching Inquiry-oriented Mathematics: Establishing Supports. IODE supported ♦ Julia Sykora as a teaching assistant for DE in Spring 2015. All of this began with a Minicourse at MathFest 2014.

I participated in a Summer 2015 MAA PREP Workshop: "Advanced Techniques in the Implementation and Creation of Process Oriented Guided Inquiry (POGIL) Activities" in Tampa, FL. This was a follow-up to a 2013 MAA PREP Workshop on POGIL.

I have designed multiple inquiry-oriented activities for my classes, most notably Introductory Statistics, the capstone in modeling, and Differential Equations. I designed some some POGIL activities for Calculus I, some funded by HHMI. I designed multiple modules to relate molecular biology to mathematics under SU's Keck Foundation grant under Dr. Maria Cuevas and others. My poster presentation, "Injections of IBL", at the 2015 RLM IBL conference, highlighted multiple activities.

I have lots of learning modules in Mathematica and some in Excel for multiple courses. During the pandemic, I relied heavily on Google Sheets, especially for Probability. I used Desmos for any sort of graphing.
I make use of the freely available StatKey and Pearson's StatCrunch.
I am learning the open source software R.

The minicourse on "Randomization Methods in Statistics" at JMM 2014 has allowed me to help students build intuition about fundamental concepts. Thanks to the 5-Lock team for their work and for the software StatKey.

Parametric Functions in Flash: Includes several examples and the ability to define your own functions: paramFull with component plots; optional comments and connectors to emphasize the relationship between the plots, paramSpeedArc with plots of arclength and speed and calculated comments , paramVec with position and velocity vectors.
These were inspired by Interactive Differential Equations at CODEE and at Pearson. Sadly, most current browsers or computer operating systems will not run the IDE simulations.
