A computer analysis of the compositions written by university students with (N=30) and without (N-60) learning disabilities (LD) found LD students were not as fluent in word production and in the number of different words used but did produce longer sentences and T-units than nondisabled peers.

Studied differences in pointing accuracy in computer-simulated mazes as a function of maze complexity and training effects. Results with 219 college students indicate that, although pointing accuracy remained higher for men, pointing performance can be modified by experience. (SLD)

This paper reports the results of a study into the quality of peer feedback provided by students within a computerised peer-assessment environment. The study looks at the creation of a "feedback index" that represents the quality of an essay based upon the feedback provided during a peer-marking process and identifies a significant…

The Bologna Declaration brought reforms into higher education that imply changes in teaching methods, didactic materials and textbooks, infrastructures and laboratories, etc. Statistics and mathematics are disciplines that traditionally have the worst success rates, particularly in non-mathematics core curricula courses. This research project,…

This dissertation reports development and validation studies of a Web-based standardized test of Japanese as a foreign language (JFL), designed to measure learners' off-line grammatical and pragmatic knowledge in multiple-choice format. Targeting Japanese majors in the U.S. universities and colleges, the test is designed to explore possible…

Most of the emphasis on mining online assessment logs has been to identify content-specific errors. However, the pattern of general "consistency" is domain independent, strongly related to performance, and can itself be a target of educational data mining. We demonstrate that simple consistency indicators are related to student outcomes,…

In a randomized experiment (n = 515), a computerized and a computerized adaptive test (CAT) are compared. The item pool consists of 24 polytomous motivation items. Although items are carefully selected, calibration data show that Samejima's graded response model did not fit the data optimally. A simulation study is done to assess possible…

The 10th International Conference on Educational Data Mining (EDM 2017) is held under the auspices of the International Educational Data Mining Society at the Optics Velley Kingdom Plaza Hotel, Wuhan, Hubei Province, in China. This years conference features two invited talks by: Dr. Jie Tang, Associate Professor with the Department of Computer…

This article provides a broad overview of the definition of web-based surveys examining some of the benefits and burdens related to using the Web for data collection. It draws upon the experience of two years of data collection on 10 university campuses demonstrating that there are noticeable differences in the speed with which web-based surveys…

This research investigates whether the Computer-Based Academic Assessment System (CAAS), a battery of tests examining speed and accuracy at performing component reading skills, would be useful for identifying reading disability in college students. One important question was whether CAAS could distinguish reading disability from non-disability or…

The purpose of this study (1,313 college student participants) was to examine the differences in paper-based and Web-based administrations of a commonly used assessment instrument, the Force Concept Inventory (FCI) (D. Hestenes, M. Wells, and G. Swackhamer, 1992). Results demonstrated no appreciable difference on FCI scores or FCI items based on…

Latent dimensions underlying individual differences in performance of information-processing tasks and dual task combinations, and the existence of a time-sharing (TS) ability were studied in 81 male college students. Supportive evidence for a general TS ability was not found. An identified TS factor specific to task combinations is discussed.…

Indices that detail aspects of student test responses include overall aberrancy; tendencies to miss relatively easy items; tendencies to correctly answer more difficult items; and a combination that indicates how the latter tendencies balance each other. Mathematics test results for 368 college students illustrate the indices. (SLD)

Conducted two experiments to determine whether scores on computerized test would differ significantly from scores on paper-and-pencil format. College students (Study 1, n=24; Study 2, n=400+) completed the Verbal Reasoning test of the Differential Aptitude Tests. Results showed reduced performance on computerized version of test. Reduced…

Evaluated the effectiveness of vocabulary computerized adaptive tests (CATs) with restricted review in a live testing setting involving 242 college students in which special efforts were made to increase test efficiency and reduce the possibility of obtaining positively biased proficiency estimates. Results suggest the efficacy of allowing limited…
