Launching a Discourse-Rich Mathematics Lesson

This article shares a mathematics discourse technique adapted from literacy instruction and designed to prepare students' engagement in a mathematics task by model mathematical thinking. The Math Think Aloud is used during the launch of a lesson to provide access to the mathematics and help students make sense of the task so they are able to work on the task and share their mathematical thinking. Successes, challenges, and tips for effective implementation are shared.

Supporting Sense Making with Mathematical Bet Lines

This article presents a mathematics discourse technique adapted from literacy instruction to promote sense making when teachers are launching a lesson about story problems. Math Bet Lines helps all students engage with the meaning of the story problem and is particularly beneficial for emergent multilingual learners. In this article we discuss how teachers implemented the Math Bet Lines technique and share their successes, challenges, and tips for overcoming those challenges.

Talk is the Ticket to Teaching Math to English Learners

This article describes a mathematics professional development program for elementary school teachers focused on improving mathematics discourse for all students, in particular emergent multilingual learners. Frameworks, such as the Math Discourse Matrix (Sztajn, Heck, & Malzahn, 2020) that characterizes four types of discourse (correcting, eliciting, probing, responsive) and other resources aimed at planning and implementing lessons that support emergent multilingual learners' engagement in productive mathematical discussions are shared.

Decomposing Practice in Teacher Professional Development: Examining sequences of learning activities

In this paper, we engage in an analysis of professional development design, examining professional development activities and the sequencing of professional learning tasks. We use a theoretical framework typically used in pre-service teacher education to understand the design of one professional development program. Our overarching goal is to theorize about how to design professional development and sequence professional learning tasks for practicing teachers.

Uncharted WATERS: Sustaining a Meaningful Student Teaching Experience Amidst a Global Pandemic via an Online STEM Curriculum

Field experience is the culminating experience for pre-service teacher training. As COVID-19 closed schools across the country, pre-service teachers’ field experiences were disrupted. This case study examines how a student teacher, a team of mentor teachers, and a university supervisor at a regional public university adapted to remote learning.

Scaling Professional Development: Preparing Professional Learning and Development Providers to Lead Power of Data Teacher Workshops.

This design-based research study examined the first two cycles of development, enactment, analysis, and redesign of the Power of Data (POD) Facilitation Academy. Professional Learning and Development (PLD) providers’ geospatial technology (GST) skills, understanding of programme principles, preparation, and stages of concern for implementing POD Teacher Workshops were investigated. The POD Team analysed previous POD PLD models.

Digital East St. Louis

Digital East St. Louis, a project supported by a National Science Foundation ITEST grant, is a collaboration between Southern Illinois University’s STEM Center and the IRIS Center for the Digital Humanities to design programming that encourages newfound interest in technology via a place-based approach to the digital humanities. I serve as the project’s curriculum director, alongside STEM’s Instructional Designer Matthew Johnson and English Professor Howard Rambsy.

New York Harbor: Resilience in the face of four centuries of development

New York Harbor is a large, iconic and complex body of water that has been extensively modified to support the development of a megacity. These modifications have affected the shorelines, water flow, water quality, habitats and living resources of the harbor. Changes in topography and bathymetry have altered the landscapes and seascapes of the region, largely to support an active shipping port and intense human settlement.
