Conventional testing systems usually give students a score as their test result, but do not show them how to improve their learning performance. Researchers have indicated that students would benefit more if individual learning guidance could be provided. However, most of the existing learning diagnosis models ignore the fact that one concept…

Smooth pursuit eye movements and saccadic eye movements in Japanese autistic, mentally retarded, and normal young children were simultaneously measured by an eye camera system (ECS) and an electro-oculography (EOG) system. The ECS was developed in the laboratory of the Research Institute for the Education of Exceptional Children at Tokyo Gakugei…

Two distinct approaches, one based on item response theory and the other based on observed item responses and standard summary statistics, have been proposed to identify unusual response patterns. A link between these two approaches is provided by showing certain correspondences between Sato's S-P Curve Theory and item response theory. This link…

The predictability of individual differences in the ability to reason about dynamic displays from tests using static displays was studied in 170 adults given paper-and-pencil and computer controlled tests. Several multivariate analyses indicated that the ability to reason about dynamic motion was distinct from the ability to reason about static…

The runs test for random sequences of responding is proposed for application in long inventories with dichotomous items as an index of sterotyped responding. This index is useful for detecting whether the client shifts between response alternatives more or less frequently than would be expected by chance. (LMO)

Compared the impact of computer-assisted psychological assessment on respondents to traditional psychometric administration procedure. Findings indicated no difference between administration methods on respondents' self-reported anxiety, electromyograph monitored stress, or task satisfaction. Moreover, computer-assisted assessment was more…

Imposing time limits on tests can serve a range of important functions. Time limits are essential, for example, if speed of performance is an integral component of what is being measured, as would be the case when testing such skills as how quickly someone can type. Limiting testing time also helps contain expenses associated with test…

Test security has often been a problem in computerized adaptive testing (CAT) because the traditional wisdom of item selection overly exposes high discrimination items. The a-stratified (STR) design advocated by H. Chang and his collaborators, which uses items of less discrimination in earlier stages of testing, has been shown to be very…

In the a-stratified method, a popular and efficient item exposure control strategy proposed by H. Chang (H. Chang and Z. Ying, 1999; K. Hau and H. Chang, 2001) for computerized adaptive testing (CAT), the item pool and item selection process has usually been divided into four strata and the corresponding four stages. In a series of simulation…

Item selection methods in computerized adaptive testing (CAT) can yield extremely skewed item exposure distribution in which items with high "a" values may be over-exposed while those with low "a" values may never be selected. H. Chang and Z. Ying (1999) proposed the a-stratified design (ASTR) that attempts to equalize item…

A study was conducted to investigate whether augmenting the calibration of items using computerized adaptive test (CAT) data matrices produced estimates that were unbiased and improved the stability of existing item parameter estimates. Item parameter estimates from four pools of items constructed for operational use were used in the study to…

Outside of large-scale testing programs, the computerized adaptive test (CAT) has thus far had only limited impact on measurement practice. In smaller-scale testing contexts, limited data are often available, which precludes the establishment of calibrated item pools for use by traditional (i.e., item response theory (IRT) based) CATs. This paper…

Syntactic processing was explored in nine individuals who stutter (IWS). Grammaticality judgments and event-related brain potentials (ERPs) were obtained while participants read sentences, half containing verb-agreement violations, via computer or paper. Judgment accuracy of IWS for the online task, but not offline, was lower, especially for more…

Studied three stratification designs for computerized adaptive testing in conjunction with three well-developed content balancing methods. Simulation study results show substantial differences in item overlap rate and pool utilization among different methods. Recommends an optimal combination of stratification design and content balancing method.…

The importance of item feedback in self-adapted testing was studied by comparing feedback and no feedback conditions for computerized adaptive tests and self-adapted tests taken by 363 college students. Results indicate that item feedback is not necessary to realize score differences between self-adapted and computerized adaptive testing. (SLD)
