While the COVID-19 pandemic disrupted educational learning, the impacts of the pandemic may vary based on student demographics. The main purpose of this study was to determine if there were differences in student performance due to COVID-19 across several demographic variables. Multilevel mixed effects models compared the effects of COVID-19 in a…

In test equating, one critical equating property is the group invariance property which indicates that the equating function used to convert performance on each alternate form to the reporting scale should be the same for various subgroups. To mitigate the impact of disrupted learning on the item parameters during the COVID-19 pandemic, a…

During the past two years, the COVID-19 pandemic has forced teachers to shift their instruction online, further exacerbating the challenges for teachers in orchestrating rich mathematics discussions. To tackle this issue, this study explored an approach that integrates online video-sharing culture (e.g., YouTube) into mathematical practices.…

This paper emerges from a broader study that investigated the strategies employed by teachers to continue mathematics teaching and learning during South Africa's COVID-19 lockdowns and through subsequent phased and partial re-opening of schools. In this paper, we focus on teacher views of the role of parents in these efforts gathered through two…

The purpose of the current research study was to investigate the extent to which student performance was influenced by the disruption to learning that occurred due to the COVID-19 pandemic. To explain observed differences in performance, we compared outcomes from a state-wide summative testing program between students who were administered the…

The aim of the study is to reveal the effect of digital comics material on students' academic success, their views on distance education, course and digital comics. In the study conducted during the 2019-2020 academic year and the pandemic, digital comics material was created in the Pixton design program for the aim of the acquisition of…

The frequentist and classical models of probability provide students with different lenses through which they can view probability. Prior research showed that students may bridge these two lenses through instructional designs that begin with a clear connection between the two, such as coin tossing. Considering that this connection is not always…

Historically, learning for young students has occurred in formal, in-person classroom environments. But in just a matter of weeks, children were mandated to transition to a completely new mode of learning, facing new learning challenges with heightened anxieties. To this end, we aim to better understand how our learning experience design (LXD)…

The COVID-19 epidemic had caused one of the most significant disruptions to the global education system. Many educational institutions faced sudden pressure to switch from face-to-face to online delivery of courses. The conventional classes are no longer the primary means of delivery; instead, online education and resources have become the…
