During the pandemic caused by SARS-CoV-2 (COVID-19), a paper analytical device (PAD) was proposed as a tool for remote laboratory classes for undergraduate chemistry to teach calibration curve concepts. For this experiment, students were taught how to prepare a PAD, calibrate standard solutions, construct a calibration curve, and treat data…

The mining industry in Brazil, despite contributing to economic growth, is one of the human activities that negatively impacts the environment. This situation can be contextualized in discussions of several curricular chemistry topics. One way in which science, technology, society, and environmental issues can be discussed in classes is through…

This article explores how middle-class Asian immigrants disrupted settled geographies and social relations in a high-tech Southern suburb. In a case study of controversies over the redrawing of the Chapel Hill school district attendance boundaries, it asks what middle-class Asian immigrants attempts to navigate the space "between Black and…

This study's general theme revolves around practical work in chemical education, and its scope is the employment of a novel inquiry strategy combined with a new openness level. We investigate how the controlled positive error, a new device for inquiry activities developed by us, affects undergraduate students' experience of an experiment and…

We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

The Arkansas Better Chance (ABC) 2023 Program Longitudinal Study 2009-2022 evaluates the kindergarten through 12th grade outcomes of participation in pre-k services in Arkansas for ABC participants from 2009 to 2021 compared to low-income students not participating in pre-K. ADE DESE data is analyzed to determine outcomes for these two core groups…

This opinion piece situates the practice of an experimental module I taught as an academic -- Chester Retold: Unspoken Stories, Put into Words -- within some theories of 'community learning'. Community learning is understood here to articulate and enact a combination of concepts taken from critical pedagogy (Freire, 2018; hooks, 1994),…

Asian and Asian American students comprise 7.5% of all participants in U.S. study abroad, compared to 9% Hispanic, 4.7% African American or Black, and 71.2% White students. However, beyond one large-scale study of academic outcomes, only three studies--all with fewer than four participants--have investigated the study abroad experiences and…

Bramlett and Drake (2013) suggest that the ability of teachers to teach proof is crucial for students to learn and develop formal and informal proofs. Teachers need to be involved in the process of proving and have a firm understanding of the critical role of proofs in order to effectively engage their students in proving activities. It is…

This investigation utilized publicly available data from the High School Longitudinal Study 2009 (HSLS:09) by the National Center for Educational Statistics (NCES) to examine any latent structures among variables which may empirically support the validity and reliability of a mathematical sense of belonging (MSB) construct. Using the nationally…

Widespread use of the Modern Language Aptitude Test (MLAT) in L2 studies of individual differences implicitly assumes that L2 aptitude is a distinct cognitive facet. There is considerable evidence for prediction from L1 abilities to L2 learning. In this longitudinal study, L1-MLAT-L2 relations were examined in 307 US secondary students based on…

In this qualitative study, the author used case study research methods to explore school practices for engaging racially, ethnically, linguistically, socioeconomically, and structurally diverse families in their children's education. In addition, this study explored how families perceive their roles in their children's education and provided space…

This applied dissertation was designed to describe the research-based practices used by middle school teachers of multilingual or ELL students in the subject area courses and the teachers' self-efficacy to implement those research-based practices while teaching. Also, this study aimed to describe the impact of professional development regarding…

One of the recognized ways to enhance teaching and learning is having insights into the behavior patterns of students. Studies that explore behavior patterns in online self-directed learning (OSDL) are scant though. In addition, the focus is lacking on how high-achieving (HA) students' behavior patterns affect the academic performance of…
