Abstract
“FOCIA” stands for Free Online Concept Inventory Analyzer. FOCIA, our new web‐based tool will allow teachers and researchers in any location to upload their test data and instantly receive a complete analysis report. Analyses included with this tool are basic test statistics, Traditional Item Analysis, Concentration Analysis, Model Analysis Theory results, pre and post test comparison, including the calculations of gain, normalized change and effect size. The tool currently analyzes data from the Lunar Phases Concept Inventory (LPCI), the Force Concept Inventory (FCI), the Astronomy Diagnostic Test (ADT), the Force and Motion Concept Inventory (FMCE) and generically, any multiple choice test. It will be expanded to analyze data from other commonly utilized concept inventories in the PER community and, from user‐designed and uploaded tools. In this paper, we will discuss the development of this analysis tool including some technical details of implementation and a description of what is available for use. Instructors and researchers are encouraged to use the latest version of the analysis tool via our website, http://www.sciedures.org.
