This paper gives a brief summary of Halliday's theory of how children learn to talk, illustrating the development of children's language from the microfunctions through the macrofunctions and into the metafunctions of adult language. The paper points to a possible source of the misinterpretation of Halliday's theory in the work of Frank Smith…

While financial aid programs exist to support enrollment in specific career fields in many states, Education Commission of the States examined only those programs that appeared in state statute and used explicit language that signaled an intent to support workforce development in high-demand fields via postsecondary credential attainment.…

In learning a language, vocabulary is the most important thing that should be mastered by learners. The English ability of primary school students is very closely related to the vocabulary mastery that they have. This research aims to find the answer to the following questions: (1) How is the application of Guess My Move Game model in learning…

Kindergarten education is becoming a priority throughout the USA as research shows its importance on later in life outcomes. The State of Washington instated full-day kindergarten for all public-school students beginning in 2016-2017. It "…is part of the state's constitutionally protected definition of 'Basic Education'" (Reykdal, n.d.,…

Background/Context: Sustained school improvement requires adequate organizational and instructional coherence, yet, in typical high schools, subject department organization, norms of teacher professional autonomy, and involvement in multiple initiatives present powerful obstacles to forging a coherent approach to improvement. This study examines…

This paper presents an architecture designed for simulation serious games, which automatically generates game-based scenarios adapted to learner's learning progression. We present three central modules of the architecture: (1) the learner model, (2) the adaptation module and (3) the logs module. The learner model estimates the progression of the…

Over the centuries, universities have functioned as gatekeepers and treasurers of received knowledge, while concomitantly furthering innovative contributions to society. Yet, when cultivating research "silos", universities encourage scholars to explore in seeming isolation. Out of such tensions, universities have supported, and will…

In Bayesian structural equation modeling (BSEM), prior settings may affect model fit, parameter estimation, and model comparison. This simulation study was to investigate how the priors impact evaluation of relative fit across competing models. The design factors for data generation included sample sizes, factor structures, data distributions, and…

Coaching is becoming widely recognized as a tool to help early childhood educators enhance teaching and build professional skills. Although effective, the use of an external coach can be cost and time prohibitive. This study examined the effectiveness of internal peer coaches as compared to external coaches in implementation fidelity of an…

Recent research makes increasing use of eye-tracking methodologies to generate and test process models. Overall, such research suggests that attention, generally indexed by fixations (gaze duration), plays a critical role in the construction of preference, although the methods used to support this supposition differ substantially. In two studies…

Meta-analytic structural equation modeling (MASEM) combines the techniques of meta-analysis and structural equation modeling for the purpose of synthesizing correlation or covariance matrices and fitting structural equation models on the pooled correlation or covariance matrix. Both fixed-effects and random-effects models can be defined in MASEM.…

Background: Stratified medicine seeks to identify patients most likely to respond to treatment. Individual participant data (IPD) network meta-analysis (NMA) models have greater power than individual trials to identify treatment-covariate interactions (TCIs). Treatment-covariate interactions contain "within" and "across" trial…

In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the "explanandum" is a logical consequence of the "explanans," which in all cases include at…

Path models with observed composites based on multiple items (e.g., mean or sum score of the items) are commonly used to test interaction effects. Under this practice, researchers generally assume that the observed composites are measured without errors. In this study, we reviewed and evaluated two alternative methods within the structural…

Funding is an important mechanism for exercising influence over ever more parts of academic systems. In order to do so, funding agencies attempt to export their functional and normative prerequisites for financing to new fields. One essential requirement for fundees is then to construct research processes in the form of a project beforehand, one…
