How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
My research is focused on the intersection between games and psychometrics. This can go from different types of gamification and game-based assessment, but it also extends to the cross-pollination between game design and test design. The concept of "the experience" of the examinees becomes a central point on this intersection, actually creating a whole approach to test design and validation. Other interests: Validity, Response process data, Admission to universities in Chile.

Students exhibit many behaviors when responding to items on a computer-based test, but only some of these behaviors are relevant to estimating their proficiencies. In this study, we analyzed data from computer-based math achievement tests administered to elementary school students in grades 3 (ages 8–9) and 4 (ages 9–10). We investigated students’...
In this study, we analyzed students’ process data (e.g., total time, first response latency) in a computer-based mathematics achievement test that included different item formats. The results indicated differences in response behaviors across item formats. Implications for test construction and future analyses in this area are discussed.
We propose an approach to test design and validation based on the study of the experiences of the examinees. We present a conceptual framework to understand the experiences and discuss how this approach will work in practice, for both test design and validation. https://ncme2021.us2.pathable.com/meetings/virtual/QHqfzuwmvm2qeXPRQ min 32 Presentati...
Chile has a centralized application system for admission to its most prestigious public and private universities. Prior to 2011, selection was based solely on the students' high school GPA and their scores in the national admission test (PSU).In 2012 an additional admission criterion was introduced-the student's class rank standing relative to prev...
Early draft of an study about the score "ranking de notas" used in the admission system to universities in Chile. Ranking de notas is a score based on high-school gpa and the relative position of the students compared with previous cohorts, in a class-rank style.
