Abstract Understanding the needs of students with and without disabilities for inclusive UDL-based design Engineering courses through learning management systems As increasingly many classes are transitioning part or all their content to online platforms, it becomes crucial identify which aspects (LMS) sufficiently accommodating from different backgrounds. We conducted a survey across undergraduate STEM at University Illinois regarding perceptions on LMS, including how (SWDs) perceive...

Forced-choice (FC) measurement has become increasingly popular due to its robustness various response biases and reduced susceptibility faking. Although several current Item Response Theory (IRT) models can extract normative person scores from FC responses, each limitations. This study proposes the Generalized Thurstonian Unfolding Model (GTUM) as a more flexible IRT model for measures overcome these The GTUM (1) adheres unfolding process, (2) accommodates scales of any block size, (3)...

University of Illinois who playfully creates and researches the use new software learning practices often

Massive open online courses (MOOCs) continue to see increasing enrollment and adoption by universities, although they are still not fully understood could perhaps be significantly improved. For example, little is known about the relationships between ways in which students choose use MOOCs (e.g., sampling lecture videos, discussing topics with fellow students) their overall level of engagement course, these likely key effective course implementation. In this paper we propose a multilevel...

Lecture material of a sophomore large-enrollment (N=271) system programming 15-week class was delivered solely online using new video-based web platform. The platform provided accurate accessible transcriptions and captioning plus custom text-searchable interface to rapidly find relevant video moments from the entire course. logged student searching viewing behaviors as fine-grained browser interaction events including full-screen-switching, loss-of-focus, incremental events,...

Noncognitive constructs are commonly assessed in educational and organizational research. They often measured by summing scores across items, which implicitly assumes a dominance item response process. However, research has shown that the unfolding process may better characterize how people respond to noncognitive items. The Generalized Graded Unfolding Model (GGUM) representing therefore become increasingly popular. current implementation of GGUM is limited unidimensional cases, while most...

Abstract Socio-cultural theory shows that significant learning takes place during social interactions and lack of opportunity to interact with others can have detrimental impact on outcomes. Moreover, not having whom students deem be ``like me'' lead feelings belonging in the field. Unfortunately, many feel isolated this isolation affects persistence success college-level Engineering courses. Given these oftentimes conditions, investigation represents an exploration understand ways which...

Understanding the meanings of domain-specific terms is essential to academic success in college-level STEM courses.However, it can be challenging for students obtain correct spellings and precise definitions from lecture videos, given limited time, rarity terms, possibly confusing pronunciations.To provide accurate speech-to-text transcription, enable search term real-time, we designed, implemented, evaluated PhraseHinter tool, a text analytics pipeline that efficiently extracts engineering...

Abstract Understanding the needs of students with disabilities (SWD) is crucial for inclusive learning in college education. Universal Design Learning (UDL)-based methodologies are recognized as a best practice to improve accessibility SWD. Although we see increased technology usage and changes course design after COVID-19, it still unclear if UDL-based practices will continue be adopted persist their use, where future opportunities more engineering education all students, SWD particular. In...

Abstract Course content plays a critical role in student success. Among all college students, students with disabilities (SWD) face numerous additional challenges when digital is inaccessible or difficult to use. Digital note-taking has been increasingly implemented and studied higher education for its potential further develop universal design learning (UDL) techniques benefit especially SWD. This study combines low-stakes assessment results surveys about accessibility, belongingness,...

Abstract Captioning of recorded video content has been available for over four decades, but its importance and pedagogical use seen a recent revival due to the legal accessibility compliance requirements MOOC online content, secondly, efforts by universities bring digital their on-campus learning environments. We present an open-source web-platform, ClassTranscribe, related practices, enhance student both during lectures, later searching viewing lectures. Using advances in automated...

Little is known about the ways that underrepresented students in online STEM courses interact and behave differently from their peers, or whether offer learning opportunities can better suit these under-served populations. The current study examines logged behavioral patterns of 470 university students, spanning 3 years, who were enrolled an introductory course. Cross-validated data mining methods applied to interaction logs determine if first generation, non-white, female, non-traditional...

Abstract This paper presents three case studies that examined the use of ClassTranscribe in a diverse set undergraduate engineering classes 2019 and 2020 at University Illinois Urbana-Champaign. ClassTranscribe, video viewing system designed with accessibility learning mind, was first presented to ASEE community [1]. The pedagogical features tool include: pause, leave resume viewing; captions available multiple languages; downloadable transcriptions; shareable links moments; searchable...

Previous research has shown that students from underrepresented minority groups tend to receive lower grades in online classes than their peers, especially science-focused courses. We propose there may also be benefits courses for these (e.g., opportunities peer discussions where status is less salient), though little currently known about potential benefits. present a new perspective on learning outcomes by measuring improvement, rather alone. In management system data seven semesters of an...

Over the past couple of decades, there has been an increasing interest in adopting ideal point models to represent noncognitive constructs, as they have demonstrated better measure typical behaviors than traditional dominance do. The generalized graded unfolding model (GGUM) consistently most popular among researchers and practitioners. However, GGUM2004 software later developed GGUM package R can only handle unidimensional despite fact that many constructs are multidimensional nature. In...
