Four experiments evaluated AMLA temporal version accuracy to measure relative luminosity in people with and without color blindness and, consequently, to provide the essential information to avoid poor figure-background combinations in any possible "specific screen-specific observer" pair. Experiment 1 showed that two very different…

This meta-analysis reviews research on the achievement effects of comprehensive school reform (CSR) and summarizes the specific effects of 29 widely implemented models. There are limitations on the overall quantity and quality of the research base, but the overall effects of CSR appear promising. The combined quantity, quality, and statistical…

Although the need for evaluation of training programs administered in organizations is recognized and widely discussed, program evaluation is not easy, and there exists a gap between discussion and practice. Cohen notes an absence of research efforts demonstrating the application of evaluation methods, particularly within control groups. This…

The purpose of the present research was to examine younger (7-years-old) and older (10-years-old) children's attitudes toward older individuals following one type of five primes: positive prime, negative prime, elderly prime, grandparent prime, or neutral prime. Overall, children's attitudes on three tests--Apperception, Semantic Differential, and…

This study explored the impact of "Technology Enabled Active Learning" (TEAL) on students learning general physics, focusing on differences between genders and among various achievement levels. A quasi-experimental investigation was conducted on two semesters of courses offered in 2008. Data sources consisted of pre-tests, post-tests,…

This guide is intended to be useful to educators in high schools and middle schools, to superintendents and school boards, and to state policymakers in planning and executing dropout prevention strategies. The target audience includes school administrators as well as district-level administrators, seeking to help develop practice and policy…

Infinity has contradictions arising from its nature. Since mind is actually adapted to finite realities attained by behaviors in space and time, when one starts to deal with real infinity, contradictions will arise. In particular, Cantorian Set Theory for it involves the notion of "equivalence of a set to one of its proper subsets,"…

Public schools face raised performance expectations on group-administered achievement tests. In response, educators have implemented various preparation strategies to ready students. However, the research community largely ignores the impact of setting on test performance. This randomized field trial assesses whether or not there were significant…

Results are presented from a formal evaluation of The Pennsylvania Bureau of State Park's Watershed Education (WE) curriculum developed for students in grades 6-12. The primary research objective was to measure the impact the training and subsequent use of the WE curriculum had on teachers' behavior, confidence, and self-efficacy in teaching about…

Many postsecondary institutions utilize learning communities to increase social engagement and attachment to the college community. In recent years, these communities have proliferated as part of a trend fueled by low retention and persistence rates, increasing reluctance of 4-year institutions to provide remedial education, and pressure on…

The purpose of this research was to manipulate the component of confidence found in Keller's ARCS Model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas University. This experiment used SAM Office 2003 and WebCT for the delivery of the tactics, strategies, confidence-enhancing e-mails…

This action research study investigated first-graders' attitudes toward being a community of learners as a result of their involvement in constructing their classroom environment. The children's attitudes throughout the year were measured through student surveys, parent surveys, student reflections, teacher reflective journal entries, and informal…

This paper presents the results of an independent two-year evaluation of the I Can Problem Solve (ICPS) universal prevention program, implemented in kindergarten and first grade classrooms in a racially and ethnically diverse urban school district. Matched pairs of schools were assigned to Instruction (i.e., treatment) or Control status. Teachers…

Objective: Shaken Baby Syndrome (SBS) is now recognized as being the main cause of severe traumatic brain injury in infancy. However, our understanding of the impact of this type of abuse on child development remains sketchy. The main objective of the current study was therefore to shed light on the cognitive dysfunctions that are particular to…

This study compares quantitative and qualitative results for task-based second language (L2) grammar instruction conducted as whole-class, teacher-led discourse (TLD) versus small-group, learner-led discourse (LLD). Participants included 78 English-speaking adults from six university classes of beginning L2 Spanish, with two assigned to each…
