A scalable method for generating hundreds of test items efficiently and economically
A methodology where models are used to create items using computer technology—it is a scalable item development process that allows subject-matter experts to generate hundreds of unique test items with a single item model.
We have worked closely with government agencies, testing companies, and academic publishers to implement item generation principles into test development practices resulting in the production of millions of unique test items using hundreds of different item models.
Coding items using a predefined taxonomy has many advantages
-Subject matter experts utilize the established meaning of content codes within the taxonomy to consistently describe AIG models and generated items.
-Subject matter expert item development training is based on the predefined taxonomy ensuring a consistent interpretation of the testable points in the test blueprint.
-The taxonomy provides a means to link to other data elements within and outside of the taxonomy to enhance the meaning of the generated items.
Make sense of AIG generated item banks using Metadata
-Enrich your item bank with metadata then filter for optimal item utilization
-Content codes, item usage, item exposure, and statistical parameters are examples of useful item bank metadata
-The number of meaningful relationships between the data elements are extraordinarily large... the possibilities are endless!
AIG scales item development to generate a large item bank – now what...
-Subject matter experts assigning content codes is an essential component to the AIG process
-The content codes describe each part of a generated item supporting effective searching, usage, and tracking of items in a large item bank
MGHL Partners – Leaders in AIG research
Our operational work is informed by our research. Topics include the importance of content coding, psychometric qualities of AIG items, the critical role of the subject matter expert in the AIG process, among many other key topics that inform our operational implementation of AIG.
The outcomes of our research are published in 2 books and over 150 research journals, conference presentations, and technical reports. Contact us for a copy of our complete bibliography.
MGHL Partners supports organization and management of an expanded item bank
Our Harvester feature is a brand-new model banking software for managing your item model bank. Once item models are ready for production, the task of searching for and tracking model use from your item models can now be managed and handled on an on-demand manner.
The user can now intuitively search for models in their model bank, place an order for items, and receive a package to their test administration software with ease.
