There has been extensive research using centrality measures in educational settings. One of the most common lines of such research has tested network centrality measures as indicators of success. The increasing interest in centrality measures has been kindled by the proliferation of learning analytics. Previous works have been dominated by…

Purpose: As a class, fricatives are more "resistant" to consonant-vowel coarticulation than other English sounds. This study investigates the relative coarticulatory resistance of /[voiceless dental fricative], s, [voiceless palato-alveolar fricative]/ in child and adult speech to better understand the acquisition of individuated speech…

Representational competence (RC) is a set of skills to reflectively use a variety of representations to draw inferences, make predictions, and support claims. Despite the important role RC plays in student success in chemistry and the considerable number of investigations into student ability to reason with representations, little is known about…

Purpose: The purpose of this study is to determine whether students' self-assessment (SSA) could be used as a significant attribute to predict students' future academic achievement. Design/methodology/approach: The authors address how well students can assess their abilities and study the relationship between this ability and demographic…

The YN vocabulary test (YN test) is a vocabulary size test that presents test takers with a list of words and asks them to answer yes to the words they know. This test may include nonwords, i.e., imaginary words added to the test to check for guessing. However, there have been no conclusive guidelines about nonword construction. One way of…

Montrul's (2008) onset age hypothesis predicts that, if attrition occurs in early bilingualism, it will be more severe in simultaneous than in sequential bilinguals. This study tested that prediction in an eye-tracking experiment focused on the processing of Spanish gender agreement during sentence reading. Heritage Spanish speakers exposed to…

Social capital concept has become popular over the past decades. What is not known in literature and worth investigating is the network designs and nature that enhance the development of new learning ideas and knowledge creation. The aim of the paper is to examine network structure dimensions, namely centrality (bonding) and structural holes…

This study aims to investigate English as a foreign language (EFL) learners' use of context information under various noise conditions. The participants were seven Japanese undergraduate students. A noise test adopted from the Speech-Perception-in-Noise (SPIN) test (Kalikow et al., 1977) was used. Four signal-to-noise ratio (SNR) conditions (SNR =…

Student grade prediction is a popular task for learning analytics, given grades are the traditional form of student performance. However, no matter the learning environment, student background, or domain content, there are things in common across most experiences in learning. In most previous machine learning models, previous grades are considered…

This qualitative case study aimed to evaluate instructional best practices in reading, particularly close reading components and strategies that can predict student success, specifically in middle school students in an inner-city setting. The implementation of close reading instructional strategies is said to impose a higher level of cognitive…

Since the world has faced the COVID-19 pandemic there has been a workforce shortage in many professions, and education is among those professions. Even before the global pandemic, education was seeing worrying levels of shortage, stress, burnout, and attrition. Teachers feel stress from the growing list of different roles and responsibilities they…

Traditional school laboratory exercises on a system of moving objects connected by strings involve deriving expressions for the system acceleration, a = (?F)/m, and sketching a graph of acceleration vs. force. While being in the form of rational functions, these expressions present great opportunities for broadening the scope of the analysis by…

In causal matching designs, some control subjects are often left unmatched, and some covariates are often left unmodeled. This article introduces "rebar," a method using high-dimensional modeling to incorporate these commonly discarded data without sacrificing the integrity of the matching design. After constructing a match, a researcher…

To investigate the grammatical constraints of code-switching (CS hereafter) under the disputes of "the constraint-based account" versus "the constraint-free account," the effects of functional category on CS have long been investigated in the existing studies. Thus, the present study, by asking 47 participants to take part in…

We commonly ask students to compare the results of their experimental measurements with the predictions of a simple physical model that is well understood. However, in practice, physicists must compare their experimental measurements with the predictions of several models, none of which may work well over the entire range of measurements. The…
