This study uses the nominal response model to investigate the effects of extreme response styles. The Zung Self-Rating Anxiety Scale (SAS) is a commonly used scale for the identification of anxiety disorders. In some cases, the response options are not extreme, ranging from "A little of the time" to "Most of the time;" in other…

Showing up for Racial Justice (SURJ) is an anti racist network in which mainly white activists participate in joint activity, the process of co-participation and co-learning in an effort to achieve racial justice. This paper focuses one chapter of SURJ in the greater Denver, Colorado area to examine the learning that emerges as critically engaged…

We used a mixed method research design to address the complexity of interrogating issues related to retention of Black mathematics teachers. The research design includes oral history interviews with retired Black mathematics teachers and large-scale survey data collected and analyzed from a Critical Race Quantitative Intersectionality approach. It…

How might teachers of elementary mathematics pursue antiracism through everyday practices such as leading whole-class discussions? This paper reports on an exploratory study of one White woman teacher's efforts to challenge manifestations of structural racism in classroom interactions with students who are predominantly Black. The results include…

Estimating student proficiency is an important task for computer based learning systems. We compare a family of IRT-based proficiency estimation methods to Deep Knowledge Tracing (DKT), a recently proposed recurrent neural network model with promising initial results. We evaluate how well each model predicts a student's future response given…

To measure individual difference in latent attributes more precisely, this study proposed a new cognitive diagnosis model (CDM), which is referred as the probabilistic-inputs, noisy conjunctive (PINC) model, by treating the deterministic binary latent attributes as probabilistic, and directly estimating the probability in the model. Simulation…

This paper argues that the emergence of design thinking and design-research provide a renewed opportunity for expansive learning, and proposes a model for educational design using concepts drawn from Activity Theory, Ecological Cognition, and other systems-based understandings of learning. The model is argued in the context of a design project…

Generalization is a critical aspect of doing mathematics, with policy makers recommending that it be a central component of mathematics instruction at all levels. This recommendation poses serious challenges, however, given researchers consistently identifying students' difficulties in creating and expressing normative mathematical…

Society's relationship to knowledge and what is considered to be factual is changing. Effective teaching models focused on leveraging strategic control of the knowledge from teachers to learners in virtual learning environments are critical to insuring a positive path is charted. The Knowledge Development Model serves as the guide for determining…

Internationalization has become a substantial part of higher education worldwide, especially in the U.S. Moreover, Chinese students make up the largest portion of the U.S.'s international higher education students. The COVID-19 pandemic has caused a disruption in higher education, especially posing considerable challenges to international…

This paper attempts to quantify the accuracy limit of "nextitem-correct" prediction by using numerical optimization to estimate the student's probability of getting each question correct given a complete sequence of item responses. This optimization is performed without an explicit parameterized model of student behavior, but with the…

In February of this year, music educators from around the state of Ohio gathered once again for the annual Ohio Music Education Association (OMEA) Professional Development Conference held in Cleveland. The research track of the conference commenced with the Graduate Research Forum featuring music education scholar Dr. Regina Carlow of the…

Dealing with multiple external representations (MERs) in science education is the key to students' understanding of science communication and becoming scientifically literate. It is generally accepted that learning scientific concepts, processes, and principles requires understanding and interacting with MERs. Science can be understood as a…

Preparing teacher candidates to enact inclusion can be challenging, particularly as teacher candidates navigate intersecting, oppressive ideologies (e.g., ableism and racism). In this paper, I present an analysis of qualitative data from a larger, multiple case study, highlighting the socio-spatial dimensions of White, non-disabled teacher…

This study employs Sfard's (2008) socio-cultural theory of Commognition to analyse student teachers' thinking and communicating practices. Specifically, we investigate the effectiveness of the student teachers' communication of a particular mathematical proof with reference of the four features of the commognitive framework (i.e., word use, visual…
