Data visualization is a powerful strategy for using graphics to represent data for effective communication and analysis. Unfortunately, creating effective data visualizations is a challenge for both novice and expert design users. The task often involves an iterative process of trial and error, which by its nature, is time-consuming. Designers…

Modern Information Technology (IT) infrastructure and open-source software (OSS) have revolutionized our ability to access and process data, enabling us to tackle increasingly complex problems and challenges. While these technologies provide substantial benefits, they often expose users to vulnerabilities that can severely damage individuals and…

Practical learning methodologies have become the need of the hour in the education sector, in particular in engineering education, to achieve technical competencies and skills.

We present a microservice architecture for large-scale automated scoring applications. Our architecture builds on the open-source Apache Storm framework and facilitates the development of robust, scalable automated scoring applications that can easily be extended and customized. We demonstrate our architecture with an application for automated…

Instructors often use spreadsheet software (e.g., Microsoft Excel) in their statistics courses so that students can gain experience conducting computerized analyses. Unfortunately, students tend to make several predictable errors when programming spreadsheets. Without immediate feedback, programming errors are likely to go undetected, and as a…

This article describes the results of a systematic review of peer-reviewed, published research articles about "discovery layers," user-friendly interfaces or systems that provide single-search box access to library content. Focusing on articles in LISTA published 2009-2013, a set of 80 articles was coded for community of users, journal…

This study is a part of the larger project that develops a sustainable digital repository of professional development resources on emerging data standards and technologies for data organization and management in libraries.
