This feature enables the student to switch from a table view of data into graph view. The student is asked to enter the data into a table and click the Switch to Graph View button on the bottom of the page. He or she can use data from real experiments in the lab. Alternatively, he or she can simply use the data that comes with the table. The data consists of temperatures that were recorded every minute while a sample of H2O was heated at a constant rate. The graph presents the heating curve of H2O.
The Rationale Behind the Feature (Specific Design Principle):
This feature enables the student to move flexibly between a tabular and visual view of data. The student can easily switch back and forth, and may modify the data at any time. This process helps to teach the student the importance of visual representations for making sense of ‘dry’ data. Without the graph, it’s much harder to evaluate the significance of the data to the phenomenon.
Context of Use:
This feature is part of a TELS project called: Phases of Matter & Phase Change (#16999) It was developed by Dalit Levy at the Concord Consortium.
