Article Co-Authored by Associate Dean Paola Sztajn Among NSF’s Community for Advancing Discovery Research in Education (CADRE)’s Most Viewed Resources of 2019

An article co-authored by Paola Sztajn, Ph.D., associate dean for research and innovation at the NC State College of Education, was one of the most viewed Discovery Research PreK-12 project resources in 2019, according to the National Science Foundation’s Community for Advancing Discovery Research in Education (CADRE).

“Supporting Sense-making with Mathematical Bet Lines,” originally published in 2016, introduces the Mathematical Bet Lines instructional strategy designed to promote classroom discourse and understanding for students, particularly those who are English Language Learners.

Developed as part of Project AIM (All Included in Mathematics), a professional development program focused on promoting meaningful mathematics discourse, the Mathematical Bet Lines strategy supports the comprehension of story problems by having students articulate predictions about what is happening in the problem, as it is revealed one sentence at a time, while the teacher facilitates student reflection through follow-up questions.

The article cited by CADRE illustrates the way one teacher implemented a lesson for her second grade students using the Mathematical Bet Lines strategy, includes reflections from other teachers on their experiences with the strategy and provides tips for classroom implementation.

CADRE is a network for STEM education researchers that helps them share methods, findings and results inside the research and development community and with the public.
