The Competentum Group (formerly known as Open Teach) works with publishers and eLearning companies to create educational content and develop educational software. 

Some recent projects we completed:

Authoring questions and inputting the questions into an online homework system.
Creating functionality for new answer types supported by LMS systems for tracking and grading assessments using Flash templates
Storyboarding, developing, and programming science simulations based on precise algorithms and multi user interactivity
Developing step by step interactive problem solving tutorials based on user input.

The Competentum Group assists organizations in these areas with our global staff of subject matter experts, media developers, and programmers.
