Kinematic models are often very useful. The back and forth throw of a ball between two ice skaters may help us appreciate the meson exchange theory of Yukawa. If the skaters throw the balls at each other, they move backward, which is equivalent to a repulsive force between them. On the other hand, if they snatch the ball from each other, the…

Latent curve models have become a popular approach to the analysis of longitudinal data. At the individual level, the model expresses an individual's response as a linear combination of what are called "basis functions" that are common to all members of a population and weights that may vary among individuals. This article uses…

Although '"models" play a significant role in engineering activities, not much has yet been developed to enhance the technological literacy of students in this regard. This contribution intends to help fill this gap and deliver a comprehensive account as to the nature and various properties of these engineering tools. It begins by…

Social networks bring both opportunities and threats to the users. On one hand, social networks provide a platform for users to build online profiles, make connections with others beyond geographical boundaries, enjoy the "openness" of social networks to meet their intrinsic need of "self-presentation", explore and strengthen…

Multiteam systems (MTS) are an organizational form comprised of two or more independent teams which share at least one common goal. These "teams of teams" can be found in all areas of life, from business to medicine, science to the military. Accordingly, it is of great interest to determine how these systems function, and what makes a…

This paper explores a causal model, using Structural Equation Modelling (SEM), in order to understand how the perceived effectiveness of the 'flipped classroom' and students' satisfaction with this technique can be affected by students' engagement in the 'flipped classroom' activities as well as the complexity and task orientation of such…

Responding to an Illinois law that took effect in 2010, the Performance Evaluation Reform Act (PERA), Chicago Public Schools (CPS) created and implemented the REACH (Recognizing Educators Advancing Chicago's Students) educator evaluation and support system. REACH was piloted in 2012-13. It is still being implemented as of the 2019-20 school year,…

We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

This study evaluated the forecasting accuracy of trend estimation methods applied to time-series data from computer adaptive tests (CATs). Data were collected roughly once a month over the course of a school year. We evaluated the forecasting accuracy of two regression-based growth estimation methods (ordinary least squares and Theil-Sen). The…

This research delves into the multifaceted landscape of various factors that influence the adoption of Generation-Artificial Intelligence (Gen-AI) in Higher Education. By employing a comprehensive framework that includes perceived risk, perceived ease of use, usefulness, Technological Pedagogical Content Knowledge (TPACK), and trust, the study…

Dialogue act (DA) classification plays an important role in understanding, interpreting and modeling dialogue. Dialogue acts (DAs) represent the intended meaning of an utterance, which is associated with the illocutionary force (or the speaker's intention), such as greetings, questions, requests, statements, and agreements. In natural language…

This study investigates the function and morphosyntax of English Embedded Language (EL) islands in Pashto-English bilingual data, using the Matrix Language Frame model to explore the role of the two languages in codeswitching and the pragmatic force behind the selection of EL islands. A dataset of 14 hours was collected from AVT Khyber, a YouTube…

This study addresses the moral and behavioral decline among Mauritian youths that followed introduction of the CPP Value-Based Differentiated model which integrates moral and spiritual values into teaching practices. Evaluation involving university and high school students, along with instructors, indicates the model's effectiveness in instilling…

Background: In the contemporary recent education landscape, an inventive paradigm known as "STEAM" has emerged, which augments the erstwhile STEM framework by incorporating the dimension of "Art". STEAM endeavors to enhance students' capacities for creativity, innovation, and design thinking. Among the various forms of artistic…

This dissertation describes a qualitative research study that grows our understanding of the career development experiences, supports, and barriers of social entrepreneurs who are gifted adults (SEGA) so that we may nurture the career development of future SEGA. Research questions for this study probed the career development experiences, supports,…
