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.

This design-based research project reports on three multilevel networks that were focused on implementing the Next Generation Science Standards (NGSS). Given the recent attention to understanding infrastructure to craft coherence in NGSS implementation, this research investigated how these networks iteratively re-designed infrastructure as they…

The study aims to investigate the regional plyometric trainings' effects on the agility performance of male volleyball players. Süleyman Demirel University Volleyball Team with 20 players attended to the study voluntarily. Players were randomly divided into volleyball training group (VTG) (n = 10) and plyometric training group (PTG) (n = 10). As…

The COVID-19 pandemic necessitated the importance of online and device-assisted learning. What was demonstrated at this time was how prepared districts were to make this transition. Lincoln Public Schools, in Lincoln, Nebraska, was one district that successfully planned and implemented device-assisted learning technology into their school system…

As series have become the entertainment of choice for today's students, educators should consider the opportunities…

Given the growing interest in retrieval practice among educators, it is valuable to know when retrieval practice does and does not improve student learning--particularly for educators who have limited classroom time and resources. In this literature review, we developed a narrow operational definition for "classroom research" compared to…

School absenteeism is detrimental to life course outcomes and is known to be socioeconomically stratified. However, the link between socioeconomic status (SES) and school absence is complex given the multidimensional nature of both family SES (e.g., income, education, occupational status) and absenteeism (e.g., truancy, sickness, suspension).…

Educator Preparation Programs (EPPs) are tasked with providing preservice teachers with pedagogical theory, practical field experiences, mentorship, and scaffolded professional dispositions during critical phases of their preparation. In addition, EPPs collaborate with school districts and state departments of education to address critical issues…

The purpose of this longitudinal study was to examine if participation in a four-year ethics curriculum strengthened college students' confidence in their own ethical reasoning ability. A longitudinal cohort of college students was followed over four years from their freshman (n = 779) to senior year (n= 545). Students' confidence in their own…

Background: Decisions related to the development and implementation of public health programmes or policies can benefit from more effective use of the best available knowledge. However, decision makers do not always feel sufficiently equipped or may lack the capacity to use evidence. This can lead them to overlook or set aside research results…

When the pandemic temporarily closed U.S. museums in March 2020, it also halted on-site museum tours. Some museums responded by developing or expanding their virtual programs, including online tours.
