1. Learning Trajectories in Digital History Education with the Library of Congress

Author

Meghan Manfra, Lindsey Payne, David Beller, Robert Coven, Lindsey Evans, Marlin Jones, Shannon Lowry, and Kasey Turcol

Abstract

The digitization of library and archive collections over the last two decades has enabled efforts to reform history education through the integration of primary sources. Currently the Library of Congress provides one of the largest digital collections of its kind. The authors' project, with support from the Library, provides social studies teachers with explicit guidance for teaching historical thinking. The authors, a group of university-based researchers and experienced social studies classroom teachers, conducted an iterative, action research study to identify learning trajectories in history education. In this article, the authors describe their process, introduce the learning trajectories matrix, and provide suggestions for integrating it into the classroom.

Abstract

In partially automated driving the vehicle takes over lateral and longitudinal control in specific situations. The driver acts as a supervisor of the driving automation system, and must be able to intervene immediately if functional limits are reached. Therefore, the driver needs to be aware of actual and planned system actions. Due to the complexity of the urban traffic environment when compared with that of well-structured highways, optimized driver-vehicle interaction is essential. The choice of a suitable display seems to be a key factor, since most information is perceived visually while driving. A promising method for supporting the driver is an Augmented Reality Head-Up Display (ARHUD). An ARHUD visualizes information at its actual location in the primary field of view in contrast to a conventional Head-Up Display (HUD). To investigate the potential of an ARHUD in comparison with a HUD, 30 participants took part in a driving simulator study experiencing a partially automated journey supported by an ARHUD or a HUD in a within-subjects design. Results show significant differences in gaze behavior for the two display concepts. The ARHUD results significantly in higher trust and lower subjective workload compared to the HUD. However, no significant differences exist in usability.
