Introduction to BASS & crasch

This seminar will introduce the BEAR Center’s assessment system software and an R package on construct modelling approach using Rasch models.

BASS
The Berkeley Assessment System Software (BASS) has been designed to facilitate the construct modeling approach to assessment design. Construct development, item design, instrument building, delivery, and scoring all occur within BASS. BASS builds on the BEAR Center's previous research in the design of assessment tasks and measurement techniques to support evidence-based assessment in the classroom. More specifically, BASS is the product of a decade of work by the BEAR Center team on a variety of software applications.

crasch
The BASS report engine is crasch, an R package written to accompany the construct modeling approach using Rasch models (construct modeling + Rasch = crasch). Though not yet implemented in BASS, the package can be used independently and is currently being used in Measurement in the Social Sciences I course on campus. A demonstration will be given to showcase the current reporting capabilities of the package using sample response data of teacher attitudes toward a school-wide writing initiative. Instructions for downloading, installing, and using the package will also be provided.
