We evaluated Samaniego and Reneau's 1994 novel weight method for eliciting subjective probability estimates. Experiment 1 replicated their experiment (subjects weighed their prior estimate against 10 new observations), with an additional weight judgment against 50 observations. In Experiment 2, subjects gave prior estimates to questions in a…

Adults' performance on a variety of tasks suggests that phonological processing of nonwords is grounded in generalizations about sublexical patterns over all known words. A small body of research suggests that children's phonological acquisition is similarly based on generalizations over the lexicon. To test this account, production accuracy and…

The aim of this study was to examine the effects of frequency of occurrence of stop signals in the stop-signal paradigm. Presenting stop signals less frequently resulted in faster reaction times to the go stimulus and a lower probability of inhibition. Also, go stimuli elicited larger and somewhat earlier P3 responses when stop signals occurred…

The judged likelihood of a focal outcome should generally decrease as the list of alternative possibilities increases. For example, the likelihood that a runner will win a race goes down when 2 new entries are added to the field. However, 6 experiments demonstrate that the presence of implausible alternatives (duds) often increases the judged…

Using differentiated instruction in the classroom can be a challenge, especially when teaching mathematics. This book cuts through the difficulties with two powerful and universal strategies that teachers can use across all math content: Open Questions and Parallel Tasks. Specific strategies and examples for grades Kindergarten - 8 are organized…

Disability laws such as the American with Disabilities Act of 1990 (ADA) and Section 504 of the Rehabilitation Act of 1973 mandate equal access to academic programs, activities, and services for students with disabilities. Therefore, disability laws require that institutions of higher education offer students with learning disabilities (LD)…

This study investigated the effectiveness of a standard protocol Tier 2 reading intervention among third and fifth grade students and the methodologies used to determine the intervention's effectiveness. Several confounding covariates were observed as a result of utilizing eligibility criteria for assignment to the Tier 2 intervention condition.…

The CSU (California State University) Chancellor's Office received a grant from the Lumina Foundation to engage in a year of planning activities to increase productivity within the CSU system. The grant is part of the Making Opportunity Affordable (MOA) initiative of the Lumina Foundation that is aimed at improving higher education productivity…

Research suggests that substantial pre-service student teaching is essential for the preparation and retention of special educators. Using logistic regression analysis, survey responses of beginning special educators were analyzed to answer the following questions: Are beginning special educators more likely to leave the field if they have had…

We present evidence that the positive relationship between kindergarten entrance age and school achievement primarily reflects skill accumulation prior to kindergarten, rather than a heightened ability to learn in school among older children. The association between achievement test scores and entrance age appears during the first months of…

It is widely reported that physical education (PE) is less popular among girls than boys. This is sometimes accounted for with reference to puberty-related physical changes associated with growing awareness of gender stereotypes. When it comes to societies which are conservative regarding women's role, such as the Muslim Arab-Israeli society, a…

Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don't calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a…

This paper uses the approach in the under/over education literature to analyze the extent of matching of educational level to occupational attainment among adult native born and foreign born men in the US, using the 2000 Census. Overeducation is found to be more common among recent labor market entrants, while undereducation is more likely among…

Objective: To examine diet- and body size-related attitudes and behaviors associated with supplement use in a representative sample of fourth-grade students in Texas. Design: Cross-sectional data from the School Physical Activity and Nutrition study, a probability-based sample of schoolchildren. Children completed a questionnaire that assessed…

For over a decade, research studies of mathematics education in high-performing countries have pointed to the conclusion that the mathematics curriculum in the United States must become substantially more focused and coherent in order to improve mathematics achievement in this country. To deliver on the promise of common standards, the standards…
