App and Web Development

I develop on mobile, responsive, cross-platform, and straight HTML5 sites, with no chaser.

Engineer and Hacker

Trained as an electrical engineer, but a maker, reuser and remixer at heart.

Research and Design

I research and evaluate the use of educational technology, while also designing some things along the way.

Portfolio of Work

Eliciting Mathematics Misconceptions

The EM2 Project is meant to validate diagnostic assessments designed to elicit 1-3 math misunderstandings and misconceptions. Served as the project's Lead Drupal developer.

Mex and the City

Mex and the City is a cultural site created to promote the free thinking, enterprising, and artistic efforts of young creatives in New York City. Currenty serving as M&TC's Future Technologist, and Project Manager for Web Development.

Congregate

An argumentation engine, were users vote on issues that matter to them and engage in civil discourse with voters who have different perspectives. Winner of McCarthur Foundation Sponsored Hackathon. Working as Ruby on Rails Lead Developer

Lei-Lei

An early childhood educational platform that supports Mexican-American children in gaining literacy skills while supporting their cultural identity, a project with Sift Kid. Please contact me if you, and your child, would like to participate in piloting a beta version of the app. Working as Lead Mobile (iOS and Android) Developer during initial funding stages and development.

Artifakts

A private project management site for researchers to use in completing protocols with shared instruments, collecting artifacts, sharing findings, and exporting data for further analysis. The project management tool is currently being used by EDC |CCT researchers for a study with Sesame Learning materials. Working as Web Lead Developer, and Researcher.

ScratchEd

A project supporting teachers in cultivating and employing design-based approaches for learning computational thinking skills with Scratch. Our work involved creating a library of computational thinking exemplars from the student screen-capture data, and piloting the assessment tools with a subset of the ScratchEd practitioner community. Served as Researcher.

PBS Kids Study

A site with transmedia (videos and games) that are meant to be used with a Pre-K supplemental curriculum. The site is organized by week, and is meant to borrow from hands on activities that support those math concepts. The interactive games are meant to be played on Chromebook laptop devices. Videos were played using an innteractive whiteboard. Working as Lead Drupal CMS Developer and Researcher.

homieOstasis

Homie Ostasis is a story about a hombeboy's explorations in the physical sciences while keepin' it real to his hometown suburban streets. The first episosde is titled "Brownian Motion" and highlights homieOstasis moving into his College of Engineering dorm room and meeting his new crew of friends. A series of 10 episodes further highlight his first year at the university.

Center for Motivation and Change

An app used by medical practitioners to track patient data such as drugs, alcohol, tobacco, and compulsive behaviors over time. The webApp allowed for quick data analysis, and calendar displays. My role was in building their second phase of programming work on a Drupal Content Management System, and testing use of the app with psychiatrists during patient visits.

EcoLogic Solutions

A data visualization app meant for touch-screen devices that promotes innovative environmentally sustainable cleaning products, and meant for for government, private, and school settings. Worked as Windows 8 Lead Developer.

Selected Publications

Mathematics in Pre-K: using digital resources to support early math learning and teaching.

This presentation results from a Prekindergarten Mathematics Study that used digital media to support early math learning. Children in the study improved significantly in their understanding of targeted early mathematics skills—counting, number recognition and subitizing, shapes, and patterns—compared to children in the Business as Usual condition. The presentation will provide insights into how the curriculum materials were developed and implemented, with a focus on describing the intertwining of digital media with hands-on activities to support early learning. The study used a randomized control trial design and was implemented in 92 prekindergarten classrooms in the New York City and San Francisco Bay areas. The presentation will describe the study structure, intervention, comparison and control conditions, and will provide details about the kinds of digital media used to support early learning as well as the curriculum supplement framework that supported their use. The presentation will be of interest to educators who want to learn about effective ways of integrating digital resources into content-area instruction for young children.

This presentation will be delivered at the Society for Information Technology Educators Conference on March 21st, 2014, in Jacksonville, Florida.

Ready to Learn

Since 2009, EDC's Center for Children & Technology and SRI International have conducted research and evaluation studies to measure children's learning outcomes under the Ready To Learn initiative. This initiative, supported by the US Department of Education, has allowed the Corporation for Public Broadcasting and PBS to develop media-rich literacy and math learning resources for young children, with the goal of improving school readiness among preschoolers in high-need communities. Our context studies have examined how technology and transmedia are incorporated into children's homes and classrooms, and our large-scale randomized controlled trials have measured the efficacy of public media in supporting children's learning.

Our most recent study examined whether a PBS KIDS transmedia mathematics curriculum implemented by teachers in early learning centers could positively affect children's math skills. The study found that to be the case—children learned significantly more math, and teachers expressed both greater comfort with technology and more confidence in their math teaching.

More information about the study is contained in a press release, available here, and in an article, "Ready and Learning," on the EDC website.
