The BEAR Assessment System Software 2.0 (BASS)

This presentation introduces the BEAR Assessment System Software 2.0 (BASS), discussing its central design principles and its main components. The development of BASS builds on more than a decade of research in the design of assessment tasks and measurement techniques to support evidence-based assessment in the classroom following a Construct Modeling approach (Wilson and Sloane, 2000; Wilson, 2004, 2009). The system currently includes modules that allow users to (a) define the model of the attributes that they are interested in assessing (i.e. construct maps); (b) create items following a myriad of system-defined item formats or, alternatively, use external items from other web-based systems; (c) define the relation between the possible item responses and the attributes through detailed scoring guides; (d) assemble and deliver of sets of items to students; (e) score student responses using automated scoring for closed format items and single or multiple raters for scoring open ended questions; (f) analyze scored data using item response models; (g) report assessment results at multiple levels (students, class, school, etc.), (h) manage different kinds of users (researchers, teachers, students) and organizational units (class, school, districts, states) with differential permissions.

The presentation will cover a brief summary of the technical characteristics of BASS, discussing both the theoretical and practical considerations that led to its current implementation as a web-based system and presenting its advantages and challenges. Then introduce the different BASS modules and the integration that the system supports among them, discussing the ways in which the system can help both researchers and teachers to streamline the use of curriculum-aligned assessments in the field. It will conclude with a live demo of BASS capabilities.

David Torres Irribarra is currently an assistant professor at the Pontificia Universidad Católica de Chile. He has a degree in Psychology from the Pontificia Universidad Católica de Chile and Ph.D. in Education of the University of California, Berkeley. David has worked as the Information Technologies Director of the Berkeley Evaluation and Assessment Research (BEAR) Center and also as a researcher at the MIDE measurement center. As a part of his work in the area of educational measurement David has worked on research projects and consultancies in Chile, Honduras, Peru, Mexico and the United States. His main research areas are (i) the application of latent variable models to measurement contexts, (ii) the theoretical foundations of measurement in the social sciences, and (iii) the use of digital technologies to improve educational assessment.
