Amidst the disruptions caused by COVID-19, maintaining learner engagement in traditional and online courses has become a significant concern. This study explores the use of embedded video questions in an undergraduate Biology course grounded in the Learning Experience Design (LXD) pedagogical paradigm with the objective to reduce cognitive load…

We explore the relationship between video playback speed and student learning outcomes. Using an experimental design, we present the results of a pre-registered study that assigns users to watch videos at either 1.0x or 1.25x speed. We find that students who consume sped content are more likely to get better grades in a course, attempt more…

This study is part of a series of in situ design-based research investigations within a large public university in California, assessing undergraduate science instruction while distance learning. It has become increasingly important to identify sustainable learning alternatives to support online teaching and learning while integrating educational…

Science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation. Leveraging the immersive nature of Virtual Reality 360 videos, we present a Design-based Research iteration testing how a novel technological-learning experience influenced our…

Remaining continually curious about students' mathematical thinking is challenging, yet worthwhile, in teaching practice. This paper describes and analyzes two video-based professional learning (PL) activities designed to help teachers go beyond their initial perceptions of what students understand and to identify what else they might learn about…

Opportunities for students to share their thinking with the class--which I refer to as "work-sharing practices--require a profound shift in who is positioned with intellectual authority in mathematics classrooms. This study explores work-sharing practices in one sixth grade mathematics classroom through an interactional lens. Video analysis…

Historically, learning for young students has occurred in formal, in-person classroom environments, but the distance learning context has opened a myriad of learning modalities. To this end, we aim to better understand how deploying learning experience design (LXD) approach supports or hinders children's engagement while participating in an…

Characterizing the nature of students' affective and emotional states and detecting them is of fundamental importance in online course platforms. In this paper, we study this problem by using discussion forum posts derived from large open online courses. We find that posts identified as encoding confusion are actually manifestations of different…

This paper discusses the implementation and evaluation of an innovative professional development program that supported 8th grade mathematics teachers in designing learning activities that assisted students in developing a conceptual understanding of mathematics. Funded by an Investing in Innovation (i3) grant from the U.S. Department of…

Quad Blogging was implemented to connect students beyond classroom walls to explore social issues. Four middle school classrooms in New Jersey, Vermont, California and Qatar served as the research sites. Students engaged in collaborative inquiry around social issues, identifying a social issue specific to their context. Final products included…

Ben Moudry has written a comprehensive overview of the current challenges facing parents, schools, administrators, and students regarding what he calls "handheld computers," commonly known as smart phones. His annotated statistics and description of American society in 2015 are frightening in their clarity, while the percentages and…

This study examines 40 teachers' perspectives on the use of video-recordings of their own mathematics lessons over two years of mathematics professional development. Data sources included an end of program survey and focus groups transcripts. Findings from this study support the use of personal video-recorded lessons in professional development.…

There are few examples of NGSS specific projects at the high school level, particularly those linking chemistry and engineering practices. Further, there are few studies that provide concrete examples of how such projects can support students' submicrorepresentations (SMRs). This study reports on the implementation of an NGSS-aligned…

A graduate course, ETEC543 ("Technology and Learning I"), was revised to better serve increasing new student population, international students, in an academic program. Project-based learning, Google Docs, and instructional strategies fostering diversity and critical thinking were incorporated into the course redesign. Observations,…

Can novel 3D models help students develop a deeper understanding of core concepts in molecular biology? We adapted 3D molecular models, developed by scientists, for use in high school science classrooms. The models accurately represent the structural and functional properties of complex DNA and Virus molecules, and provide visual and haptic…
