One important decision that English language teachers should make is to decide on a pronunciation model. This decision should be based not only on mere preference, but also on technical information. This paper seeks to review the Lingua Franca Core (LFC), a pronunciation model proposed by Jennifer Jenkins (1998, 2000) in an attempt to facilitate…

Acquiring a basic understanding about the composition of crystal structures and the resulting structure-property relationship is central for chemists and material chemists, enabling the prediction of desired properties and the solution of a wide range of current challenges in sciences, e.g., the development of clean-energy storage. For a deeper…

Through a series of explorations, this article will demonstrate how the Kentucky Derby winning times dataset provides various opportunities for introductory and advanced topics, from data processing to model building. Although the final goal may be a prediction interval, the dataset is rich enough for it to appear in several places in an…

All states have some system of music teacher certification, and most, according to the 2018 "Analysis of State Music Education Certification Practices in the United States" from the National Association for Music Education, require broad-based music certification that includes both choral and instrumental music at levels K to 12.…

The purpose of the present study was to apply the methodology developed by Raykov on modeling item-specific variance for the measurement of internal consistency reliability with longitudinal data. Participants were a randomly selected sample of 500 individuals who took on a professional qualifications test in Saudi Arabia over four different…

The university reward structure has traditionally placed greater value on individual research excellence for tenure and promotion, influencing faculty's allocation of time and definition of worthwhile labour. We find gender differences in Canadian natural sciences and engineering faculty's opinions of the traditional criteria for measuring…

A lack of alignment between professional practice and education has triggered the move to alternative educational models, often with detailed scripts and templates to be followed. Among these are variants of problem/case-based models, where learners are challenged to achieve professionally desired learning outcomes and acquire knowledge and skills…

Schools are being confronted with an increasing population of high-functioning students with autism spectrum disorder (HFASD). These students pose particular challenges to school-based practitioners and teachers given their social-communication deficits, restricted and repetitive behaviors/interests, and relative cognitive and language strengths.…

In this reflective conceptual essay, we critically examine two complementary models related to leadership for community engagement--the boundary-spanning model (Weerts & Sandmann, 2010) and the preliminary competency model for CEPs (Dostilio, 2017a). Both models organize and present prioritized activities necessary for individuals to advance…

Mixture item response theory (MixIRT) models combine IRT models with latent class model and assume that there exist latent subpopulations in the data. Identification of latent subpopulations via MixIRT models produces more detailed information. Detailed information about the response processing of examinees provides a better understanding of the…

Educational researchers have long advocated for the integration of computer simulations (sims) in science courses, citing the positive effects these tools have on students' science conceptual comprehension (Develaki 2017; Hannafin, West, and Shepard 2009; Lamb et al. 2011). In fact, Liao (2007) investigated the learning differences between…

According to the Felder and Silverman Learning Styles Model (FSM), students have learning preferences regarding how information is obtained, processed, perceived and understood. The Index of Learning Styles (ILS) is an online questionnaire created by Felder and Soloman to classify students according to their learning styles. With a priori…

One of the unique advantages of electrochemistry is that the relationship between thermodynamics and kinetics is quantitative, which is the basis of voltammetry. Mathematical models of electrochemical systems take advantage of this relationship to predict the effect of changing a system property (e.g., concentration, scan rate, or rate constant)…

Purpose: The purpose of this paper is to explore creativity and how it changes over time among engineering students in practice-based entrepreneurship in higher education. This change was examined in students over a one-semester course in entrepreneurship. Entrepreneurship courses that use creativity tools for practice-based learning are expected…

Homework has traditionally been considered positive for students' academic achievement, to the extent that it makes children more responsible while learning. Nevertheless, making students do a large amount of homework has been one of the most criticised practices in recent years. Parental associations have long held the view that Spanish…
