There appears to be no published knowledge regarding how humans use unit conversions. Until very recently, acquiring such data would be essentially impossible, but mobile devices have now enabled many questions to be answered through passive "crowdsourcing" of big data sets. This work details the analysis of five years of anonymous user…

Australian universities are increasingly resorting to the use of journal metrics such as impact factors and ranking lists in appraisal and promotion processes, and are starting to set quantitative "performance expectations" which make use of such journal-based metrics. The widespread use and misuse of research metrics is leading to…

The current use of two sets of units in the UK continues to be a source of muddle and confusion. Young people are taught metric (SI) units in school but, in the outside world, still have to contend with units such as inches, feet, pounds, stones and miles. Specialist teachers and practitioners of the sciences are not blameless. This paper…

The need for educational programs to show their return on investment is exemplified in the intense debate surrounding gainful employment programs--defined as programs that lead to gainful employment in a recognized occupation and theoretically differ from programs that offer education in the liberal arts or prepare students for further education.…

The Individuals with Disabilities Education Improvement Act (IDEA) of 2004 and the No Child Left Behind Act of 2002 (NCLB) require that students with disabilities have equal access to general education curricula and contexts. Florida's Differentiated Accountability Program (DAP) is designed to support educators in meeting IDEA and NCLB…

Background: Return on investment (ROI) is one of the most popular evaluation metrics. ROI analysis (when applied correctly) is a powerful tool of evaluating existing information systems and making informed decisions on the acquisitions. However, practical use of the ROI is complicated by a number of uncertainties and controversies. The article…

The authors investigated four spelling scoring metrics: total words correct, correct letter sequences, correct sounds, and phonological coding scoring (developed by Tangel and Blachman) across two studies with children in kindergarten. The relationships between spelling scores and measures of reading, phonological awareness, and writing skills…

An investigation of factors which differentiate between university lecturers in relation to publication output is reported. The study drew on data from lecturers working full-time at two large Australian universities. Measures of research publication output were used to select two groups of lecturers (N[subscript 1] = 119; N[subscript 2] = 119);…

In this article, 93 Greek university departments were evaluated according to their academics' h-index. A representative sample from the fields of social sciences and humanities, sciences, engineering, pharmacy and economics was adopted. In the reported study, 3354 (approximately 1 out of 3) academics serving in Greek universities were evaluated.…

The University of Westminster began collecting and analyzing vendor usage reports since starting their e-book collections in 2004. They have used the results both to monitor the use of the collections and to calculate basic cost-per-use metrics that have informed decisions on whether to renew particular resources. In 2008, they sought to extend…

Education leaders across the country confront a growing challenge: too many students are not college ready when they leave high school. Although indicators exist to identify students at risk of dropping out of high school, few indicators of students' college readiness are currently in place, and few districts have linked indicators to practices…

Digital resources play an increasingly important role in academic libraries, which must demonstrate their value to the institution and their impact on student learning outcomes in new and more compelling ways. This study examines 5 years of vendor-supplied e-resource usage data in conjunction with other library and institution measures. Results…

Consonant mastery is one of the most widely used metrics of typical phonological acquisition and of phonological disorder. Two fundamental methodological questions concerning research on consonant acquisition are (1) how to elicit a representative sample of productions and (2) how to analyse this sample once it has been collected. This paper…

Summarizes results of a survey that examined 13 textbooks claiming to use SI units. Tables present data concerning the SI and non-SI units actually used in each text in discussion of fluid pressure and thermal energy, and data concerning which texts do and do not use SI as claimed. (CS)

Describes several studies that challenge conventional wisdom regarding the teaching and learning of nonstandard and standard unit, rulers, and measurement sense. Discusses the educational implications of their results. (Author/CCM)
