Effective personalization of education requires knowing how each student will perform under certain conditions, given their specific characteristics. Thus, the demand for interpretable and precise estimation of heterogeneous treatment effects is ever-present. This paper outlines a new approach to this problem based on the Leave-One-Out Potential…

We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…

Massive Open Online Courses (MOOCs) are a promising form of online education. However, the occurrence of academic dishonesty has been threatening MOOC certificates' effectiveness as a serious tool for recruiters and employers. Recently, a large-scale study on the log traces from more than one hundred MOOCs created by Harvard and MIT has identified…

For decades, researchers and practitioners have made a great deal of effort to study a variety of methods to increase parameter accuracy, but only recently can researchers start focusing on improving parameter estimations by using a joint model that could incorporate RT and students information as CI. Given that many tests are currently…

Examinee response times from a computerized adaptive test taken by 204 examinees taking a certification examination were analyzed using a hierarchical linear model. Two equations were posed: a within-person model and a between-person model. Variance within persons was eight times greater than variance between persons. Several variables…

This paper recounts the use of a computerized multiple-measures placement model at Yuba College in Marysville, California. Yuba began using computerized placement tests in 1994, based on suggestions from faculty and student assessment staff. Two years later, a set of multiple measures criteria, consisting mainly of self-reported high school…

This study examined the effects of high school course choices, grades, and Grade Ten Assessment Test scores (GTAT) in math and reading, along with race and gender, on student performance on a computerized placement test (CPT) administered upon entry to community colleges in Florida. The sample consisted of 19,736 African-American, white, and…

Forty-eight college students participated in an ABAB analysis; the A condition was online study groups and the B condition was individual online quizzes. The effect of A and B on student satisfaction and achievement was determined. The Index of Learning Styles categorized students on four dimensions of learning style (active-reflective,…

Research on the major computerized adaptive testing (CAT) strategies is reviewed, and some findings are reported that examine effects of examinee demographic and psychological characteristics on CAT strategies. In fixed branching strategies, all examinees respond to a common routing test, the score of which is used to assign examinees to a…
