Introduction: The use of averaged topic-level scores can result in the loss of valuable data and can cause misinterpretation of the effectiveness of system performance. This study aims to use the scores of each document to evaluate document retrieval systems in a pairwise system evaluation. Method: The chosen evaluation metrics are document-level…

Despite federal and state laws and regulations that require states and local districts to provide English language learners (ELLs) with support services, prior research has indicated that ELLs are, in general, lagging behind non-ELLs in academic achievement. An unanswered question is whether the initial designation of students as ELL influences…

Higher education institutions choose to invest in upward reclassification for their athletics program with anticipation of generating increased revenue and exposure for their school; however, this could have a detrimental effect on their student-athletes' academic progress. This study examined the relationship between four classifications of…

In the quest to raise student achievement in low-performing urban schools, researchers often point to the central importance of recruitment and retention of a high quality teacher workforce (Lankford, Loeb and Wyckoff 2002; Rivkin, Hanushek and Kain 2005; Jacob 2007). At the same time, advocates have proposed charter schools not only as a means to…

If Christian schools desire students to achieve higher-level thinking, then the textbooks that teachers use should reflect such thinking. Using Risner's (1987) methodology, raters classified questions from two Christian publishers' fifth grade reading textbooks based on the revised Bloom's taxonomy (Anderson et al., 2001). The questions in the A…

The role of teacher preparation programs is to ensure that candidates are effectively prepared in the knowledge, skills and dispositions needed to be an effective educator. However, dispositions have always been a challenge to the field of teacher education, particularly in response to assessing dispositions and in answering the question; can…

With its critical assessments of scientific evidence on the effectiveness of education programs, policies, and practices (referred to as "interventions"), and a range of products summarizing this evidence, the What Works Clearinghouse (WWC) is an important part of the Institute of Education Sciences' strategy to use rigorous and relevant…

The objectives of this study were to investigate the alignment of exam questions with course learning outcomes in a first year biology majors course, to examine gaps and overlaps in assessment of content amongst the sections of the course, and to use this information to provide feedback to the teaching team to further improve the course. Our…

OBJECTIVES OF THIS STUDY WERE TO DESIGN AND TEST A TAXONOMY OF ILLUSTRATIONS OF 4 TYPES--PHYSICAL (PICTURES), VERBAL MODIFIER (CAPTION), EDUCATIONAL OBJECTIVE, AND SUBJECT MATTER. CHI-SQUARE ANALYSIS OF ASSOCIATION AMONG THE TYPES IN A SAMPLE OF 40 GRADE 8 TEXTS IN 4 SUBJECT AREAS WOULD SUGGEST HYPOTHESES FOR FURTHER SYSTEMATIC RESEARCH RELATING…

A linear classification rule (used with equal covariance matrices) was contrasted with a quadratic rule (used with unequal covariance matrices) for accuracy of internal and external classification. The comparisons were made for seven situations which resulted from combining three data conditions (equal and unequal covariance matrices, minimal and…
