The temporal stability of the effects induced by the Cued Reaction Time Task (CRTT) on the orienting of attention was assessed across four weekly sessions. Benefits, costs, and validity effects were computed for each session, and the correlation coefficients between each session were calculated (interindividual stability index). Intraindividual…

The No Child Left Behind Act (NCLB) has placed a significant focus on standards. Understandably, classroom teachers are focused on effectively covering their content area standards and are often reluctant to add information literacy skills to their lessons because they see no direct connection to the state achievement tests. However, a close…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) public-use data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), which includes the first release of the public version of the third-grade data. This manual mainly provides information specific…

The paper aims to improve the Thurstone scaling method by reducing the workload of data collection and simplifying the procedures of application. It proposes a hierarchical structure for organizing items that are to be scaled. Instead of making paired comparisons, the respondents would be asked to rank the items. The ranks of the items would then…

Software metrics are measures of software products and processes. Metrics are widely used by software organizations to help manage projects, improve product quality and increase efficiency of the software development process. However, metrics programs tend to have a high failure rate in organizations, and developer pushback is one of the sources…

Differentiation is an instructional approach that considers a student's learning readiness, learning style, and learning interest to meet academic needs. This curriculum innovation is grounded in the multiple intelligence theory of learning. It is also one method of meeting the expectations of the No Child Left Behind initiative. While the current…

This Policy Information Perspective provides a status report on efforts to measure the high school graduation rate more accurately and use it more constructively. The first section of the report discusses obtaining reliable national survey data on the graduation status of young adults and of the population as a whole. The second section makes the…

Reasoning about and making sense of statistics and probability are essential to students' future success. This volume belongs to a series that supports National Council of Teachers of Mathematics' (NCTM's) "Focus in High School Mathematics: Reasoning and Sense Making" by providing additional guidance for making reasoning and sense making part of…

U.S. enrollment in science and engineering (S&E) graduate programs in 2007 increased by 3.3% over comparable data for 2006. This is the highest annual growth rate since 2002 and is nearly double the 1.7% growth rate seen in 2006. First-time, full-time enrollment of foreign students (the terms "foreign student" and "temporary" visa holder are…

This report discusses findings and implications of a study commissioned by the College Board to inform the development of the Voluntary Framework of Accountability for Community Colleges. CCRC researchers identified the performance indicators that states are already using for their community colleges and interviewed state higher education…

In state needs assessment meetings held in late June 2008, the leadership of two Central Region state departments of education, South Dakota and Missouri, asked Regional Educational Laboratory (REL) Central to determine how the states in the region evaluate their supplemental educational service (SES) providers. Specifically, these SEA staff…

We used four different methods to determine the best means of assessing over 200 preservice elementary teachers' growth in knowledge of models and their use in K-8 classrooms while participating in the Science Capstone course that focused on the unifying themes of models in science. Each assessment method probed a different aspect of models (from…

The purpose of this review is to integrate and summarize specific measurement topics (instrument and metric choice, validity, reliability, how many and what types of days, reactivity, and data treatment) appropriate to the study of youth physical activity. Research quality pedometers are necessary to aid interpretation of steps per day collected…

In the journal "The Chronicle of Higher Education," an article by Geoffrey Nunberg criticizes Google's Book Search (GBS), emphasizing that disturbing errors are endemic. He recognizes that for mainstream "googling" purposes, "they don't really care about metadata provided by a library catalog." In perhaps his most discouraging point, linguistics…

What does it cost to provide early intervention services? Data collected as part of the National Early Intervention Longitudinal Study were used to determine expenditures for infants, toddlers, and their families receiving services through Part C programs. The study found that the national average total expenditure for early intervention services…
