Learning from text is a "constructive" activity in which sentence-level information is combined by the reader to build coherent mental models. With increasingly complex texts, forming a mental model becomes challenging due to a lack of background knowledge, and limits in working memory and attention. To address this, we are taught…

It has been shown in multiple studies that expert-created on-demand assistance, such as hint messages, improves student learning in online learning environments. However, there are also evident that certain types of assistance may be detrimental to student learning. In addition, creating and maintaining on-demand assistance are hard and…

When designing an instructional tool and using it in pedagogical activities, it is essential that designers and users understand what pedagogical affordances and constraints the tool provides to support its successful integration into targeted pedagogical activities. Toward this end, we developed "Pedagogical Affordance Analysis (PAA)."…

Many studies have shown that visual representations can enhance student understanding of STEM concepts. However, prior research suggests that visual representations alone are not necessarily effective across a broad range of students. To address this problem, we created a novel, scaffolded form of diagrammatic self-explanation in which students…

MOCCA-C is an assessment of adult reading ability designed for early diagnosis of reading problems, for formative assessment in reading intervention planning, for assessment of reading improvement over time, and for assessment of reading intervention outcomes. It uses both narrative and expository reading passages and it currently has four forms.…

The concept of equivalence can be elusive to students and can be confounded with unproductive understandings of the equals sign. Using the game-based digital algebraic notation system, From Here to There! (FH2T), students explore ideas of equivalence by dynamically transforming expressions or equations among mathematically equivalent states. In…

This study examined if and how thinking time, defined as the time from the start of the problem to the students' first action to solve, influences their problem-solving efficiency, defined as the number of steps taken to solve the problem, using Graspable Math, a web-based mathematical tool. We found that: (1) students who took longer to think…

This study investigated the impact of conversational agent formality on the quality of summaries and formality of written summaries during the training session and on posttest in a trialog-based intelligent tutoring system (ITS). During training, participants learned summarization strategies with the guidance of conversational agents who spoke one…

Women in physics and engineering continue to remain underrepresented in higher education. To illuminate underlying processes, we used data from undergraduate Physics students (N= 338) enrolled in an introductory physics course to investigate the development of field belonging and its association with gender and perceived competence. Latent change…

This paper presents three case studies that examined the use of ClassTranscribe in a diverse set of undergraduate engineering classes in 2019 and 2020 at the University of Illinois at Urbana-Champaign. ClassTranscribe, a video viewing system designed with accessibility and learning in mind, was first presented to the ASEE [American Society for…

Underrepresented (UR) students face barriers to help-seeking in traditional classrooms. We predicted these barriers would be ameliorated online. We analyzed online course discussion boards and found UR students asked for help more often than non-UR students and women were more likely than men to ask for help explicitly at least once. Furthermore,…

Students' language in discussion forums in online courses can influence their participation and course outcomes. We examined aspects of gendered language to gain insight into men's and women's participation and success in two online science courses. Results revealed that women and men did not differ in their language use along traditionally…

An intelligent textbook may be considered to be an interaction layer that lies between the text and the student, helping the student to master the content in the text. The Mobile Fact and Concept Training System (MoFaCTS) is an adaptive instructional system for simple content that has been developed into an interaction layer to mediate textbook…

This paper reports on a quasi-experimental pilot study of the impacts of a high school teacher professional development (PD) series. The 10-session series, "Engaging High School Students in Academic Work," was designed to equip teachers to deepen students' learning and engagement and thereby increase course-passing rates. The study took…

Given the rapid growth of research-practices partnerships (RPPs), we need a framework that helps the field understand how RPPs can facilitate mutual learning for those involved. Drawing on both cultural-historical and organizational learning theories, we argue that learning can happen in RPPs for both researchers and practitioners at the…
