Meet the Exchange
Leading a sector-wide effort to tackle collective action problems in education starting with edtech purchasing and implementation.
We help educators make better-informed decisions about technology.
Founded in 2018, we are a nonprofit structured as a public charity funded entirely through grants from a growing list of funders, including the University of Virginia School of Education, Strada Education Network, Carnegie Corporation of New York, and the Chan Zuckerberg Initiative.
Our team is made of a community of educators, edtech experts, and district decision-makers committed to coming together to solve our shared problem: a lack of information about what edtech works where and why.

Dr. Christine Tomasik, NBCT is the Chief of Staff and Director of Partnerships at the EdTech Evidence Exchange.
At the EdTech Evidence Exchange Christine builds relationships while leading and directing internal and external special projects. She is a “utility player” with a passion for advancing strategic initiatives collaboratively with colleagues and partners who “dream big, have fun and get stuff done.” When it comes to selecting and implementing education technology, Christine values merit over marketing and knows #ContextMatters.
Prior to joining the EdTech Evidence Exchange, Christine was the Chief Learning Officer at mindSpark Learning and led the organization’s Learning Team which created and delivered relevant, highly interactive and engaging professional learning experiences for educators nationwide.
Christine was also the Director of Special Projects at the George Washington University Graduate School of Education and Human (GSEHD). She led several of GSEHD’s multi-faceted, interdisciplinary projects and managed the sponsored research portfolio for the Office of the Dean. During her tenure at GW, Christine led programs that facilitated the professional growth and development of thousands of the region’s educators.
Christine began her career as a 4th grade teacher in Philadelphia, holds an Advanced Professional Certificate from the state of Maryland, and is certified by the National Board for Professional Teaching Standards as a Middle Childhood Generalist. She earned her doctorate in Human and Organizational Learning from George Washington University. Across her 20+ years in education, she’s taught elementary and middle school aged children from diverse backgrounds in both urban and suburban settings, supervised pre-service teachers, conceptualized and led a graduate certificate program, earned $5M+ in grant funding, and developed and led the National Board Candidate Support Network in Montgomery County (MD) Public Schools.
Dr. Kate Tindle is the Director of Field Research at the EdTech Evidence Exchange.
At the EdTech Evidence Exchange, Kate works directly with school partners to gather contextual EdTech implementation data from teachers and administrators. This data tells the story of what is and is not working in their schools – and why. She builds strong research teams by recruiting and training highly qualified research assistants who support onsite data collection. The research team engages in collaborative data analysis in ways that value teacher voice into how and why EdTech implementation works or doesn’t work in their context.
Kate began as a middle school science teacher in public schools along the East coast. Over her 15 years, she worked in leadership roles to elevate teacher voice in school-based decisions. She worked with new teachers and student teachers to help them navigate their multifaceted responsibilities and understand the complex learning needs of students and how to meet them.
Kate left the K-12 classroom to prepare pre-service teachers for high-needs urban schools at The George Washington University. The teacher preparation program Kate directed involved developing a technology-infused literacy curriculum for high school students with low reading levels. There were computers for every student and other types of technology such as Whiteboards and literacy software. This allowed Kate to facilitate innovative integration of EdTech tools through the lessons pre-service teachers created and delivered to high school students.
As a researcher, Kate has conducted many educational program evaluations and studies involving teacher perceptions. When she directed urban teacher preparation at GW, she looked into what contextual factors influenced pre-service teachers’ instruction to make them effective with their students. She also researched teachers’ perceptions of when, during their preparation program, did they recognize themselves as teachers, and what factors contributed to that recognition. Kate is committed to learning about the how and why of teachers’ experiences directly from teachers, to elevate their voice in the research and to make their professional lives more transparent and understandable to them and to the field.

Dr. Emily (Barton) Kohler is a full time research assistant professor at the University of Virginia School of Education and Human Development in the Center for Advanced Study of Teaching and Learning. Dr. Kohler consults for the EdTech Evidence Exchange as our Director of Research, leading research efforts to achieve the Exchange mission and vision. Dr. Kohler led the research components of the EdTech Genome Project, a national effort to discover and define the contextual factors that contribute to the success or failure of edtech implementations. Dr. Kohler is currently working with the Exchange team to develop and populate the EdTech Evidence Exchange Platform, crowdsourcing research evidence from educators across the county.
Dr. Kohler began her career in education as a middle school special education teacher, where she was inspired by the potential of classroom technology. She strove not only to find innovative ways for technology to support learning in her own classroom but also to support her colleagues’ technology integration.
Dr. Kohler received her PhD in Instructional Technology from the University of Virginia where she taught courses for preservice teachers on instructionally-grounded technology integration. Using a design thinking framework, Dr. Kohler aimed to provide students with the tools necessary to implement educational technology in a rapidly changing digital world such that it adds value for student learning and addresses instructional challenges.
As a researcher, Dr. Kohler has worked on the Institute of Education Sciences-funded projects such as MyTeachingPartner-Math/Science and CANLEAD. Through her work on CANLEAD, Emily focused on how leaders learn about and support technology integration such that teachers learn about and carry-out high-quality integration. She is particularly interested in mixed methods design, using qualitative methods to explore and deepen understanding of quantitative relationships. Drawing together her work in instructional design and research, Dr. Kohler considers new ways to present and communicate research to a wide audience such that we can expand the reach of new knowledge.
The time has come to give the education professionals the mechanism, shared language, incentives, and support they need to document their work for the common good.
We know that the effectiveness of technology in the classroom depends on a constellation of factors, from school culture to technical capacity to support from school and district leadership.
