This paper shows how a freely downloadable and powerful software package, "SMath Studio," can be used to model physical systems in physics teaching. The software can form the basis of lecture demonstrations by teachers or can be used individually by students working in an educational environment or on their own home computers.

Computer adaptive testing is an important research field in educational measurement, and simulation studies play a critically important role in CAT development and evaluation. Both Monte Carlo and Post Hoc simulations are frequently used in CAT studies in order to investigate the effects of different factors on test efficiency and to compare…

A comprehensive, accessible introduction to educational research "Educational Research: Competencies for Analysis and Applications" uses engaging, straightforward language to introduce students to the information and skills required to successfully conduct research and to competently evaluate research. Long known for their clear and at…

Model selection is important in any statistical analysis, and the primary goal is to find the preferred (or most parsimonious) model, based on certain criteria, from a set of candidate models given data. Several recent publications have employed the deviance information criterion (DIC) to do model selection among different forms of multilevel item…

Web application software uses new technologies that have novel methods for integration and state maintenance that amount to new control flow mechanisms and new variables scoping. While modern web development technologies enhance the capabilities of web applications, they introduce challenges that current testing techniques do not adequately test…

This study compared five common multilevel software packages via Monte Carlo simulation: HLM 7, M"plus" 7.4, R (lme4 V1.1-12), Stata 14.1, and SAS 9.4 to determine how the programs differ in estimation accuracy and speed, as well as convergence, when modeling multiple randomly varying slopes of different magnitudes. Simulated data…

This longitudinal study explores how the language proficiency of eight (N = 8) US-affiliated university students developed relative to their smartphone usage during study abroad (SA) in Paris. Phone usage was tracked daily with Space, proficiency weekly using NCSSFL-ACTFL Can-Do statements, and language use monthly via a Language Engagement…

Academic writing is a key determinant to be successful in higher education institutions, and graduation requirements often involve students producing theses and dissertations using academic writing skills after conducting research. The COVID-19 pandemic has greatly affected pre-service teachers' learning in higher education institutions, and with…

This systematic review provides an overview of existing evidence regarding the effect of touchscreen technology on young children's learning. Using PRISMA principles, we identified 53 studies in our review. The literature generally advocated positive effects of touchscreen devices on young children's learning with 34 studies reporting positive…

Visual bookmarking app Pinterest, known for its aspirational and consumptive qualities of users' "pinning" work, has recently made concerted forays into the online advertising and marketing space. At the same time, its visual and collaborative qualities offer unique potential for application in pedagogy. This paper describes a…

The study focused on how university students constructed proof of the Fundamental Theorem of Calculus (FTC) starting from their argumentations with dynamic mathematics software in collaborative technology-enhanced learning environment. The participants of the study were 36 university students. The data consisted of participants' written…

Online discussions have become important educational activities through which collaborative learning and knowledge construction can be facilitated. This study explores the use of two online discussion tools, online discussion board and VoiceThread, for supporting online course discussion activities among a group of graduate students and…

There is growing awareness of the need for mathematics and computing to quantitatively understand the complex dynamics and feedbacks in the life sciences. Although several institutions and research groups are conducting pioneering multidisciplinary research, communication and education across fields remain a bottleneck. The opportunity is ripe for…

In recent years, with the more powerful functions of smartphones, the use of sensors integrated by mobile phones as an auxiliary tool for physical experiment teaching has become more popular. Combined with the related mobile phone apps, people easily can develop and expand the physical experiment contents of mechanics, optics, acoustic phenomena,…

What can eye movements reveal about reading, a complex skill ubiquitous in everyday life? Research suggests that gaze can reflect short-term comprehension for facts, but it is unknown whether it can measure long-term, deep comprehension. We tracked gaze while 147 participants read long, connected, informative texts and completed assessments of…
