The Spectrum Laboratory is an online data visualization tool and associated set of investigations that supports students in learning about light, color, and the electromagnetic spectrum by working with authentic scientific spectral data. The research study investigates factors that hinder or promote students' reasoning about spectra; and to determine how the curriculum can help students to use spectra to explore interesting questions about the world while gaining fluency with a range of important science practices.
This is a 4-year, level II Exploratory study within the teaching strand of DRK12. The research explores the functioning and impact of a nationally-developed STEM professional development model within the Navajo Nation. Teacher participants represent the entire K-12 grade range and multiple content areas, and they all participate in an innovative STEM-content, culturally responsive, 8-month professional development fellowship. We explore the extent to which culturally responsive principles are evident in their self-authored curriculum units.
The purpose of this study has been to address the accessibility and efficacy of high quality professional development by modifying a successful in-person PD to be delivered on the edX platform. The PD course introduces BioGraph, a curriculum that uses computer-based simulations to teach biology concepts and complex systems ideas. The study has taken place over the last four years with teachers from across the globe, and in biology classrooms across the US and in India with teachers and students who are working with the BioGraph curriculum.
Analyzing Instruction in Mathematics using the TRU framework (AIM-TRU) is a research-practice partnership that is investigating the pressing problem of supporting teachers in increasing their capacity to implement high-quality instructional materials in the classroom with fidelity. Drawing upon the design-based research paradigm, the partnership has worked to co-design, investigate, and iteratively form the AIM-TRU Learning Cycle, which gives teachers the opportunity to understand the materials and how they are used in the classroom through a video-based professional learning cycle.
The Teacher Engineering Education Program is designed to support teacher learning in engineering education in an 18-month online asynchronous program. In this project, we collected data from two cohorts of elementary teachers (N=26) including multiple interviews throughout the program, teachersâ€™ video recordings of their classroom teaching, and their coursework in the four required courses. This poster summarizes our central findings on teacher learning in the program, looking at teachersâ€™ noticing and pedagogical sensemaking in engineering.
Our team works with high school chemistry teachers to co-develop a suite of curricular materials that engage students in making sense of chemical phenomena in terms of atomic/molecular behavior. This suite of materials undergoes a regular cycle of development and refinement, guided by teachersâ€™ sense of â€œwhat worksâ€ when implementing the materials and observations of classroom discourse practices. Our work investigates how to best support teachers as they design learning environments to promote student sensemaking.
The goal of the design and development study, Proof in Secondary Classrooms (PISC), is to develop an innovative intervention to support the teaching and learning of mathematical proof in secondary geometry. PISC made use of features of lesson study and continuous improvement. Findings featured in the poster involve quantitative assessment results from pre-tests and post-tests administered over three years. Overall, the PISC curriculum had a statistically significant, positive impact on students' end-of-year results.
The main issue our project addresses is how students' reasoning about mathematics concepts that are not new to them (e.g., linear functions) changes when learning about a new concept (e.g., quadratic functions), and we call this phenomenon backward transfer. We specifically focus on mathematics, but believe our backward transfer research is highly relevant within and across STEM content domains more broadly.
