Geometry is a strand of mathematics that can benefit individuals in many areas of life. Test results, such as the TIMSS results, indicate that geometry is an area for growth among American students. With a need for students to better understand geometry, several academic standards have been created to direct geometry instruction in the United…

While there are many studies on students' collaborative learning at the small group level, pedagogies and strategies for supporting students' collaborative learning at the class level are underexplored. This study proposes a pedagogical model named the Spiral Model of Collaborative Knowledge Improvement (SMCKI) to inform the design and…

We report a molecular modeling study for undergraduate students aimed at carrying out an analysis of small molecules using a systematic conformational search with VEGA ZZ, a freely available software program. Conformational analyses were performed using a systematic search based on variations of torsion angles. First, the conformations of n-butane…

The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.

Transition metrics, which quantify the propensity for one event to follow another, are often utilized to study sequential patterns of behaviors, emotions, actions, and other states. However, little is known about the conditions in which application of transition metrics is appropriate. We report on two experiments in which we simulated sequences…

Bidirectional naming is an important ability which enables children to acquire listener and speaker behaviors through exposure to relevant word-object associations. Many children with autism spectrum disorder (ASD) or developmental delays do not demonstrate this ability and require systematic instruction. The purpose of the present study was to…

Construction management education in the architecture, engineering, and construction (AEC) domain is increasingly challenged with managing limited resources while increasing instructors' teaching effectiveness and improving students' learning outcomes. To address this challenge, the authors proposed a new automated activity-on-node (AON)…

A Computer-Assisted Language Learning (CALL) application, TextMix, was developed as a proof-of-concept for applying Natural Language Processing (NLP) sentence chunking techniques to creating 'sentence scramble' learning tasks. TextMix addresses limitations of existing applications for creating sentence scrambles by using NLP to parse and scramble…

Educator professional development has the power to affect day-to-day educational practice. Every school district wrestles with planning professional development for improving educators professionally to better student achievement. With the largest portion of the budget being spent on personnel, developing educators and staff professionally should…

Prior to the COVID-19 pandemic, online learning was a contested issue within higher education. Advocates of online higher education saw it as a way to make college more accessible and affordable and bring high-quality education to those who might not be able to attend in-person classes. However, many faculty were skeptical or reluctant to teach…

Pollution from quarry activities has a substantial environmental impact on many countries. This issue should be addressed accordingly as its impact may introduce various health-related problems to the surrounding community. One alternative is to increase awareness for the younger generation and society at large. However, environmental data…

The development of technology-enhanced innovative items calls for practical models that can describe polytomous testlet items. In this study, we evaluate four measurement models that can characterize polytomous items administered in testlets: (a) generalized partial credit model (GPCM), (b) testlet-as-a-polytomous-item model (TPIM), (c)…

Background: As educational digital technologies are increasingly being used in schools, past research left unanswered the question of these technologies' impact on the socioeconomic achievement gap even when equal access is guaranteed. Objectives: The objectives of the present study are to examine whether and how the socioeconomic achievement gap…

The primary aim of this study was to investigate the methodological trends of the articles published in the "Computer Assisted Language Learning (CALL)" journal between 2014 and 2019 via content analysis. The secondary aim was to analyze the "CALL" journal with the bibliometric mapping method to reveal the keyword trend and…

This article puts to use the work of Deleuze and Guattari to build new knowledge and understanding associated with the circumstantial nature of becoming a technology-capable language teacher through experimentations with/in the agencements of an ongoing research project associated with the design and delivery of a 12-week online graduate course in…
