Research-based educational technology platform that engages students and teachers in math learning and computational thinking through game design and physically active math gameplay. The platform, open to grades 4 and up, allows students to play mobile math games, design their own games, pose math problems, and program them using a no-code programming language. Developed with learning science principles at its core, WearableLearning aims to improve computing education through embodied learning (mind-body) and game-based learning techniques.

The Wearable Learning Computing Education project is funded by the National Science Foundation (NSF).

Usable Math: Elementary Problem Solving and Design OER

Math problem solving strategies are provided by four coaches.

Usable Math (formerly 4mality) is a digital playground for math learning through problem-solving and design. The platform provides interactive problem-solving practice for 3rd through 6th-grade students learning mathematical reasoning and computation through creative writing, no-code slideshow design, and human-AI collaboration. Usable Math features four coaches – Estella Explainer, Chef Math Bear, How-to Hound, and Visual Vicuna – who offer reading, computation, strategy, and visual strategies for solving math problems. The platform aims to teach mathematics concepts and problem-solving skills based on the Massachusetts Mathematics Curriculum Framework and the Common Core State Standards for Mathematics while supporting ISTE Standards for Students.

The Usable Math elementary math problem-solving and design resource is run independently by myself, Sharon, and Bob. We are grateful to MassCUE Classroom Grant for supporting our initiative with iPads. 


MathSpring Intelligent Tutoring System

MathSpring is a free, equitable, and AI-based smart math tutor for grades 4 and up, backed by National Science Foundation grants. The platform has helped over 50,000 students across the United States, with users showing a 30% improvement in accuracy on MCAS problems after just one hour of instruction/usage. MathSpring offers 24/7 math help via intelligent learning companions, instant access to lessons, and real-time progress reports for students and parents. The platform provides live dashboards for teachers to monitor student performance and emotional analysis, aiding in understanding student progress and suggesting when and who needs further assistance. MathSpring incorporates socio-emotional learning (SEL) and adopts Common Core literacy standards to personalize instruction based on students' recent performance.
