Abstract:
In this short talk, we present the results of a multi-disciplinary collaboration between earth scientists, education researchers and computer scientists, including undergraduate and graduate students and faculty. The goal of the project was to design a set of curricular components that teach about climate change and computational thinking in a synergistic manner. We utilized a Snap! extension called NetsBlox. NetsBlox is an open source, browser-based visual programming environment and corresponding cloud-infrastructure that integrates distributed programming capabilities at a level accessible for novice programmers. One of the new abstractions, Remote Procedure Calls (RPCs) provide students’ programs access to online services and data sources including Google Maps, weather, NOAA climate change data, and others, as well as services created by the end-user community and hosted on the NetsBlox server. RPCs enable students to create engaging and motivating projects grounded in real-world applications.
In studying climate change, we aimed for learners to discover patterns across modern and paleoclimate datasets, and to formulate hypotheses about causal relations between change in climate and data on components of the atmosphere as measured or recovered. This project has thus focused on data visualization and exploratory data analysis with large and diverse data sets. To enable secondary-school learners to engage with the data, we have focused on NetsBlox as a visual environment for iteratively refining data search and processing algorithms. Because the objective is to give learners a flexible set of tools for finding patterns and anomalies; for creating data proxies for human social impact on climate; and for proposing and testing causal relations, the work has been oriented toward platform advances that enable teachers to publish datasets and connect computational thinking with leading exploratory data analysis tools.
