Research suggests that allowing individuals to control their own practice schedule has a positive effect on motor learning. In this experiment we examined the effect of task difficulty and self-regulated practice strategies on motor learning. The task was to move a mouse-operated cursor through pattern arrays that differed in two levels of…

Standardized and nonstandardized assessments of phonological awareness skills were administered to two groups of 6-year-old children. Group 1 passed a language screening but exhibited mild or moderate phonological impairments on the "Assessment of Phonological Processes--Revised." Group 2 passed a language screening and exhibited no phonological…

Studies that examine the impacts of education interventions on key student, teacher, and school outcomes typically collect data on large samples and on many outcomes. In analyzing these data, researchers typically conduct multiple hypothesis tests to address key impact evaluation questions. Tests are conducted to assess intervention effects for…

This study investigated the relationship between parenting stress and relational conditioning. Fourteen students who were not mothers, 14 mothers who reported high parenting stress and 14 mothers with low parenting stress completed two matching-to-sample (MTS) computer tasks, each requiring formation of three 3-member classes. The first MTS task…

Differential performance results occur when a specific population subgroup achieves a passing rate which is significantly lower than that of the normative reference group. African Americans do less well, in general, on all types of assessments, including constructed-response tests. The present study examined the writing styles of African American…

Although SAS PROC CALIS is not designed to perform multigroup comparisons, it is believed that SAS can be "tricked" into doing so for groups of equal size. At present, there are no comprehensive examples of the steps involved in performing a multigroup comparison in SAS. The purpose of this article is to illustrate these steps. We demonstrate…

This qualitative case study investigates Chinese university English in the context of foreign language (EFL) learners' attitudes about video-aided instruction (VAI), video recording instruction, and mobile phone instruction (learning technologies). When I was working as an English teacher in Mainland China, several instructors and students stated…

When researchers use the Guttman scalogram rather than multidimensional techniques, scalogram error assignment techniques should be questioned. An alternative to the customary minimizing error rule is suggested through ALAM and ALAS criteria which use ordinal information in scalable item marginals. (Author)

A new estimator of the actual error rate for the two-group discriminant problem is presented. The new estimator is based on the concept of a shrunken generalized distance. This new estimator is compared favorably to two modified distance estimators and an estimator developed by M. Okamato. Four figures are included. (Author/TJH)

This study of errors in references made to Edward O. Wilson's book and W. D. Hamilton's articles test the charge that writers frequently lift their bibliographic references from other publications without consulting the original sources. Twelve references are cited. (EJS)

To establish the spatial generality of perseverative errors in infant manual search, a group of infants aged 8-11 months performed Piaget's Stage IV task with an object hidden at successive locations in the vertical plane. (Author/JMB)

Addresses general performance errors in weight training, also discussing each category of error separately. The paper focuses on frequency and intensity, incorrect training velocities, full range of motion, and symmetrical training. It also examines specific errors related to the bench press, squat, military press, and bent- over and seated row…

Human motion animation has been one of the major research topics in the field of computer graphics for decades. Techniques developed in this area help present human motions in various applications. This is crucial for enhancing the realism as well as promoting the user interest in the applications. To carry this merit to e-learning applications,…
