The Ocean Tracks web interface and curriculum modules have been created using several grants from the National Science Foundation. The interface was developed and pilot tested with high school students in four classrooms during the spring and fall of 2013. In 2014, we were funded to make further refinements to the interface and develop curriculum modules for undergraduate students. The modules have been iteratively tested by 14 undergraduate faculty between 2014 and 2017, yielding interesting new insights into how working with data can develop data analytic and critical thinking skills. We are currently seeking funding to better understand the essential role teacher facilitation plays in developing students' data literacy skills, and to broaden the reach and impact of the Ocean Tracks resources.
