Poorer performance in conditions involving task repetition within blocks of mixed tasks relative to task repetition within blocks of single task is called mixing cost (MC). In 2 experiments exploring 2 hypotheses regarding the origins of MC, participants either switched between cued shape and color tasks, or they performed them as single tasks.…

This paper advances the literature on technology use in educational settings by analyzing the antecedents and an outcome of technology use. The study investigates the role of "form of technology," which is defined here as the location of use (e.g., inside or outside the classroom) and the type of use (e.g., active or passive). The technology…

During adolescence the body undergoes many physical changes. These changes necessitate an updating of internal models of action. Here, we tested the hypothesis that internal models undergo refinement between adolescence and adulthood. We investigated the chronometry of executed and imagined hand actions, which relies on internal models, in 40…

Instructors and trainers are increasingly using online education and technology-mediated learning (TML) to supplement or replace traditional approaches to classroom teaching. Because mandatory involvement requirements may not intrinsically motivate learners to achieve high quality learning, social factors with commitment, such as identification…

The Chinese government's stated objective of student financial aid (SFA) policy is to help students from low-income families to access higher levels of education. This article first explores the possible associations between the distribution of SFA and students' various demographic and academic backgrounds. Then it presents the findings regarding…

Building upon earlier confirmatory factor analytic research that validated a second-order, three-factor structure of the Beck Depression Inventory for Canadian and Swedish nonclinical adolescents, this study tested the factorial structure of the Swedish version of the instrument separately for 559 males and 537 females, and tested its measurement…

To test the hypothesis that learning depends on the influence and interaction of three primary variables--instruction, learner aptitude, and learning environment--an explanatory model was tested during the 1967-68 school year in an experiment conducted with the cooperation of a simple random sample of 56 teachers drawn from the National Science…

The relative power of the Mann-Whitney statistic, the t-statistic, the median test, a test based on exceedances (A,B), and two special cases of (A,B) the Tukey quick test and the revised Tukey quick test, was investigated via a Monte Carlo experiment. These procedures were compared across four population probability models: uniform, beta, normal,…

The latency to classify a test item as not being from a memorized list of category words is usually slower when the test items are categorically related to memorized words than when they are unrelated. This observation has been explained by four models of recognition, which are evaluated here. (Editor/RK)

Discusses criticisms of behavioral science research methodologies, and offers solutions which emphasize that it is only on the basis of theory that one can decide on an appropriate hypothesis to be tested, on a correct method of statistical analysis, and on whether the experimental results can be generalized to a population of interest. (Author/KS)

When evaluating the utility of a psychological test for clinical decision making, both the psychometric properties of the test (i.e., the reliability and validity of the instrument) and the ambiguity of the language by which test results are interpreted or communicated need to be considered. Although each has been studied independently, to date…

Second in a three-part series, this article provides suggestions for the development of theoretical models in which issues and questions in economic education can be conceptualized and formally stated as empirically testable hypotheses. (Author/RM)

According to the stage-learning hypothesis, children's ability to learn is constrained by their pretraining stages of cognitive development. Some procedures for obtaining unconfounded tests of this hypothesis are developed in this paper, and some applications to factorial experiments are considered. (Author/BW)
