In July 2009, President Barack Obama set out a bold higher education agenda for his administration and promised that the U.S. would once again lead the world in college degree attainment. Given the nation's current level of college completion, it is reasonable to wonder whether such ambitions are feasible. While there is a sense that the country…

The impact of Web 3.0, also known as the Semantic Web, on online learning is yet to be determined as the Semantic Web and its technologies continue to develop. Online instructors must have a rudimentary understanding of Web 3.0 to prepare for the next phase of online learning. This paper provides an understandable definition of the Semantic Web…

The amount, complexity and provenance of data have dramatically increased in the past five years. Visualization of observed and simulated data is a critical component of any social, environmental, biomedical or scientific quest. Dynamic, exploratory and interactive visualization of multivariate data, without preprocessing by dimensionality…

The current study explores students' abilities to make different metacognitive judgments about the same material. Sophomores in a psychology class indicated how confident they were that each answer on their final was correct (micro-level judgments) and pre- postdicted their overall score (macro-level judgments). Students made the series of simpler…

This study explored the extent to which sequential auditory grouping affects the perception of temporal synchrony. In Experiment 1, listeners discriminated between 2 pairs of asynchronous "target" tones at different frequencies, A and B, in which the B tone either led or lagged. Thresholds were markedly higher when the target tones were temporally…

A principle of efficient language production based on information theoretic considerations is proposed: Uniform Information Density predicts that language production is affected by a preference to distribute information uniformly across the linguistic signal. This prediction is tested against data from syntactic reduction. A single multilevel…

Meta-analysis of studies with two groups and two measurement occasions must employ order-one effect size indices to represent study outcomes. Especially with non-random assignment, non-equivalent control group designs, a statistical analysis restricted to post-treatment scores can lead to severely biased conclusions. The 109 primary studies…

This study investigates the possibility of analyzing educational data using the theory of rough sets which is mostly employed in the fields of data analysis and data mining. Data were collected using an open-ended conceptual understanding test of the living things administered to first-year high school students. The responses of randomly selected…

As educators in academic programs featuring interdisciplinary learning, the authors can attest that helping undergraduate students in an interdisciplinary studies major engage in interdisciplinary learning--that is, draw from two or more disciplines to advance understanding of a problem, question, or phenomenon--is no mean feat. Consequently, the…

Purpose of the Study: To examine the effects of the present on admission (POA) indicator on the prevalence of and factors associated with postsurgical adverse events in older patients. Design and Methods: This is a secondary data analysis of 82,898 surgical patients aged 65 years or older in 252 acute care hospitals in California in 2004. Four…

Text comprehension plays a fundamental role in the processes of acquisition, sharing, and construction of knowledge. Most definitions share the focus on the interaction between text and reader's prior knowledge. In this paper both direct and indirect effects of prior knowledge on reading comprehension have been analyzed, along with other…

Introductory science courses often have laboratory components in which students are required to write formal lab reports as homework. These reports often have problems such as incorrect data analysis, mistaken conclusions, and unclear graphs, all errors that indicate that students often fail to understand the experiments. Plagiarism is also…

National longitudinal databases hold much promise for school counseling researchers. Several of the more frequently used data sets, possible professional implications, and strategies for acquiring training in the use of large-scale national data sets are described. A 6-step process for conducting research with the data sets is explicated:…

The use of The Three Stooges' films as a source of data in an introductory statistics class is described. The Stooges' films are separated into three populations. Using these populations, students may conduct hypothesis tests with data they collect.

The purpose of this study was to assess some of the effects of a nontraditional, experimental learning approach designed to improve rapid acquisition and long-term retention of quantitative communication skills (QCS) such as descriptive and inferential statistics, hypothesis formulation, experimental design, data characteristics, and data…
