J. S. Hardin; G. Sarkis; P. . URC – Journal of Statistics Education, 2015
We use the Enron email corpus to study relationships in a network by applying six different measures of centrality. Our results came out of an in-semester undergraduate research seminar. The Enron corpus is well suited to statistical analyses at all levels of undergraduate education. Through this article's focus on centrality, students can explore…

From Number Lines to Graphs in the Coordinate Plane: Investigating Problem Solving across Mathematical Representations
Peer reviewed Peer reviewed
Direct linkDirect link
Earnest, Darrell – Cognition and Instruction, 2015
This article reports on students' problem-solving approaches across three representations--number lines, coordinate planes, and function graphs--the axes of which conventional mathematics treats in terms of consistent geometric and numeric coordinations. I consider these representations to be a part of a "hierarchical representational…

The Interplay of Graph and Text in the Acquisition of Historical Constructs
Peer reviewed Peer reviewed
Direct linkDirect link
Shand, Kristen – Theory and Research in Social Education, 2009
Graphs are often conjoined with text passages in history textbooks to help students comprehend complex constructs. Four linkages connect text and graphs: appropriate elements, fitting patterns, suitable labels and causal markers. Graphs in current textbooks contain few such linkages and seldom mirror the construct under study. An experiment…
