**CURRENT PROJECTS**

**ERP Markers for Conventional and Unconventional Number Gestures**

The goal of this project is to characterize the ERPs for automatic processing of number gestures. Previous behavioral research has shown that finger counting and montring habits influence recognition of number gesture configuration. We explore the ERP differences in recognition of different number gesture configurations (counting, montring, unconventional). The task involves identifying different number gestures, one condition showing conventional number gesture representations (e.g., index, middle, and ring fingers up for number “3”), and the second showing unconventional gestures (thumb, index, and little fingers up for number “3”). The analysis focus on the differences between the temporal aspects of processing these different gestures, one automatic the other non-automatic.

**The Relation between Fingers and Arithmetic Processing**

This project is a collaboration with Dr. Sharlene Newman's Cognitive Neuroimaging Lab at Indiana University. We study how children's finger skills skills correlate with and predict arithmetic skills, and the neural mechanisms underlying this relation.

**Bilingual Mathematics**

This project is a collaboration with Dr. Lisa Hsin's ECS Lab. Our goal is to explore mathematical development of and number processing in bilingual children and adults.

**Fraction Learning**

Fraction operations are difficult, specially for children. Being able to understand fractions requires the development of intuitions not carried by natural numbers. One strategy that has been successful in developing fraction understanding in children has concentrated in making the link between the notation of fractions and their numerical value. The numerical value of a fraction is called the fraction's magnitude. This study looks at the ERP components of fractions' magnitude processing to identify the strategies that successfully employ fraction magnitude to solve math problems.

**Predictive Modeling of Educational Interventions**

This project is a collaboration with Drs. Hyemin Han and Kangwook Lee. We explore how different modeling and machine learning techniques can be applied to predict outcomes of large-scale learning interventions based in small-scale implementation data.

**Computational Thinking in STEM Learning**

Given that computational modeling has revolutionized all fields of science, acquiring computational thinking skills is an essential aspect of STEM learning. In the ModelSim project (PI: Uri Wilensky, Northwestern) we studied scaled implementation of computational modeling units in high school science classes in the Chicagoland area.
