CAFA: Assessment Engineering Platform

Welcome to Computer Adaptive Formative Assessment(CAFA) Assessment Engineering platform!

What is Assessment Engineering?

Assessment Engineering(AE: Bejar, 1993; Embretson & Yang, 2007; Gierl & Haladyna, 2013; Irvine & Kyllonen, 2002) is an assessment theory and practice that integrates cognitive science with digital technologies for futuristic digital assessments. AE provides innovative solutions to overcome the shortcomings of the traditional analogous approach in which human writers manually create, review, revise, and analyze individual items which is a slow, expensive, and often subjective procedure.

The essence of AE is Automatic Item Generation(AIG) or Computerized Item Modeling(CIM) which is an approach to program Item Models for Machine to strategically generate a large amount of high-quality digital items and assessments for various digital learning contents and services. AIG is a symbolic technique/theory of the initial step, the so-called \”item-to-item model\” transition, for the digital transformation of assessment and education. (Choi, 2017)

What is CAFA Platform?

CAFA platform (CAFA Lab, Inc., 2012) is a futuristic Assessment Engineering engine for conducting research and development of digital assessment projects such as Computer Adaptive Formative Assessment, Learning Analytics Platform, Intelligent Assessment/Learning Agent. CAFA platform allows users to incorporate various digital technologies to effectively and efficiently develop computerized item models that can generate large quantities of assessments strategically optimized in the digital environment.

CAFA platform will evolve into a full-scale assessment tool including below functionalities:

  • assembling assessments with generated items
  • deploying the assessments to collect response data in both on- and off-line modes
  • conducting advanced psychometric analyses with the collected data

The current version of CAFA platform focuses on the capability of developing item and assessment (e.g., Worksheet) models and generating innovative digital learning contents and services.
