This study concerns how intra-organizational networks affect the implementation of policies and practices in organizations. In particular, we attend to the role of the informal subgroup or clique in cultivating and distributing locally adapted and integrated knowledge, or know-how. We develop two hypotheses based on the importance of…

This paper introduced the features of scaffolding to the development of instructional interaction in online foreign language learning, and testified their effects on learners' perceived usefulness, perceived ease of use, sense of community, and continuance intention by the integration of the Technology-Acceptance Model and the Organizational…

A comprehensive exploration of 21st Century school politics, "Teachers versus the Public" offers the first comparison of the education policy views of both teachers and the public as a whole, and reveals a deep, broad divide between the opinions held by citizens and those who teach in the public schools. Among the findings: (1) Divisions…

It is essential that pre-service teacher educators address pre-service teacher numeracy but with careful consideration as it incorporates more than mathematics skills. Numeracy also involves disposition towards mathematics--attitudes, confidence and mathematics anxiety; that is, the level of willingness to use mathematics skills. As part of an…

The aim of the study is to question the current state of ICT and to determine the role of it in schools via teachers' perspectives. The study is a qualitative study and was designed as a phenomenological research. A semi-structured interview form was used to collect the data. The participants were selected in accordance with the criterion and…

Gamma-family measures are bivariate ordinal correlation measures that form a family because they all reduce to Goodman and Kruskal's gamma in the absence of ties (1954). For several gamma-family indices, more than one variance estimator has been introduced. In previous research, the "consistent" variance estimator described by Cliff and…

Whether human infants spontaneously represent number remains contentious. Clearfield & Mix (1999) and Feigenson, Carey & Spelke (2002) put forth evidence that when presented with small sets of 1-3 items infants may preferentially attend to continuous properties of stimuli rather than to number, and these results have been interpreted as evidence…

In standard treatments of probability, Pr(A[vertical bar]B) is defined as the ratio of Pr(A[intersection]B) to Pr(B), provided that Pr(B) greater than 0. This account of conditional probability suggests a psychological question, namely, whether estimates of Pr(A[vertical bar]B) arise in the mind via implicit calculation of…

Sophisticated, software-based security systems can provide powerful tools to support campus security. By nature, such systems are flexible, with many capabilities that can help manage the process of physical protection. However, the full potential of these systems can be overlooked because of unfamiliarity with the products, weaknesses in security…

Paul Newton (2010), with his characteristic concern about theory, has set out two different ways of thinking about the basis upon which equivalences of one sort or another are established between test score scales. His reason for doing this is a desire to establish "the defensibility of linkages lower on the continuum than concordance."…

Marked gender differences in three-dimensional mental rotation have been broadly reported in the literature in the last few decades. Various theoretical models and accounts were used to explain the observed differences. Within the framework of linking item design features of mental rotation tasks to cognitive component processes associated with…

This paper presents Programming Adaptive Testing (PAT), a Web-based adaptive testing system for assessing students' programming knowledge. PAT was used in two high school programming classes by 73 students. The question bank of PAT is composed of 443 questions. A question is classified in one out of three difficulty levels. In PAT, the levels of…

District-level policymakers are challenged to use evidence of student achievement to make policy decisions, such as professional development and other school improvement plans. They currently receive reports of student achievement data that are complex, difficult to read, and even harder to interpret. Using the research literature on policymakers'…

Correct dimensionality identification (i.e., a correct decision on the number of factors to retain) is crucial not only in educational and psychological measurement, but also in various fields such as medicine and sociology that use exploratory factor analysis (EFA) in developing theories. However, to date, no single method has been endorsed for…

An interpreter's role is to facilitate communication and convey all auditory and signed information so that both hearing and deaf individuals may fully interact. The common types of services provided by interpreters are: (1) American Sign Language (ASL) Interpretation--a visual-gestural language with its own linguistic features; (2) Sign Language…
