SUDDS Collaborates with Researchers from University of Haifa

Team News
Last week, the SUDDS team hosted two days of meetings with Dr. Michal Yerushalmy and Dr. Shai Olsher, two prominent math education researchers from the University of Haifa, Israel. The meetings kicked off with the Joseph D. Moore seminar, during which Dr. Yerushalmy and Dr. Olsher delivered a presentation to faculty and students in the College of Education, titled “Mapping the terrain: Developing content & pedagogy meta-data categories for learning resources.” Following the presentation, Dr. Yerushalmy, Dr. Olsher, and the SUDDS team met to share insights from their work relating to digital formative assessment and learning trajectories, as well as to discuss potential areas for future collaboration. The discussions left the SUDDS team feeling energized and excited to find ways to continue to collaborate with Dr. Yerushalmy and Dr. Olsher, and their group,…

Ratio Design Study: What We Learned Last November, we conducted a design study with our partners at Highland Middle School, in which teachers used a SUDDS-designed curriculum and our cluster assessments to teach a sixth-grade unit on ratio. We spent a long time afterwards analyzing the data from the study, and have compiled some recommendations for teachers teaching ratio in a blog post. What's New in Math-Mapper A robust practice environment. This feature, available to students in our partner schools, offers real-time feedback on specific questions, so students can see their progress along the learning trajectory. Students can choose to practice a specific construct in the map and focus on progress levels where they need the most practice. For information on accessing and using practice, see this document.

SUDDS Ratio Study: Takeaways for Teachers

Articles
As a follow-up to our design study of a sixth-grade ratio unit at Highland Middle School in Harnett County, NC, we analyzed student responses to several assessments that teachers administered over the course of the unit. The assessments included: A pretest administered before the beginning work on the SUDDS ratio curriculum that included items from cluster 4, Finding Key Ratio Relationships, and cluster 5, Comparing Ratios and Finding Missing Values. A Cluster Assessment of Progress (CAP) was administered for cluster 4 after completing the cluster 4 curriculum. A CAP was administered for cluster 5 after completing the cluster 5 curriculum. A SUDDS-designed posttest containing items from both cluster 4 and cluster 5 was administered after completing and reviewing the cluster 5 curriculum. An independent assessment containing ratio items, was administered…

Our Dynamic Number Line Tool is Now Available to All!

Team News
Teachers and students can now access our dynamic number line tool for free. The tool is a great way for students to explore fractional reasoning, integer operations, irrationals, the development of the real number system, and more. We suggest students and teachers first work through our set of example assessment items (and share your thoughts through the feedback form at the bottom of the page) before going further with the blank slate version. Let us know what you think!
