Even before the pandemic slowed learning for many, only 39 percent of California students demonstrated proficiency on the state math assessment. During the pandemic, the proportion of math-proficient students fell to one-third. At the same time, the STEM workforce faces shortages and a lack of diversity, which call into question the longstanding…

In the spring of 2020, a global pandemic caused an immediate transition to online, synchronous learning platforms in much of the world. In discussion-based classrooms, where students construct learning from the material and their interactions with each other, the shift posed new challenges to educators and students. This mixed methods action…

The idea of "threshold concepts" has been used to identify discipline-based concepts that are critical to that academic area. Threshold concepts are often difficult for students to assimilate in a meaningful way but, once done, can be powerful for the learner. In general, threshold concepts are 1) transformative to learner thinking; 2)…

The purpose of this qualitative phenomenological research study was to investigate the factors that influence mathematical instruction of upper elementary teachers in school districts within Southern California. More specifically, this research study examined teaching strategies of upper elementary teachers' experiences and perceptions regarding…

My dissertation examines undergraduates' online learning experiences during the COVID-19 pandemic through three distinct studies. The primary goal of my dissertation is to shed light on crucial aspects of social cognitive learning theories and learning experience design (LXD) applied in distance learning. These studies, using an LXD approach…

National University's Master of Science in Educational Counseling underwent a revision in 2022 utilizing the approach of deriving program learning outcomes directly from the California Teaching Commission standards for school counselors. The program is offered solely in an online format. This study was undertaken to assess the program in terms of…

The goal of greater student engagement has led districts to turn to technology, specifically, one-to-one (1:1) or a device for every student. This qualitative case study explored teachers' mobile device use to implement high-leverage instructional practices that engage students, advance equity, and improve student learning outcomes for underserved…

The authors are a group of Western-trained biologists (seven students and one faculty member) from diverse cultural backgrounds, who spent a semester exploring how they might complement their epistemological approach to addressing real-world problems by including possibilities outside the Western-scientific methodology. Their study focused on how…

The COVID-19 pandemic has led to immediate school closures resulting in online learning. Online learning under such circumstances has presented challenges for teachers of students with mild to extensive support needs. The current study interviewed twenty special education teachers about the strategies they used when teaching online and the…

Access to core subject-area curriculum for students from immigrant backgrounds who are learning the dominant language of instruction has long been a barrier to equitable education around the world, especially in secondary schools. This article explores the promise of Complex Instruction (CI) to address barriers to access for such multilingual…

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…

ePortfolios are considered the eleventh high-impact practice (HIP) by the AAC&U (now the American Association of Colleges and Universities). They have been widely implemented in the humanities but remain underutilized in STEM fields. The benefits of engaged learning, metacognitive awareness, and professional identity development in those…

This research captures the experiences of high school graduates who were labeled English Learners while they were enrolled in a public high school in the greater Sacramento area of California. The study examined what these bilingual high school graduates report as beneficial and detrimental experiences faced while completing the course…

This study examines whether "My Math Academy," a digital game-based learning environment that provides personalized content and adaptive embedded assessments, can improve math knowledge of Transitional Kindergarten and Kindergarten students. A cluster randomized study was conducted with 20 classrooms, 10 of which were randomly assigned…

With a rise of alternative permit (AltPermit) teachers coming to education, many have little to no preparation or self-efficacy for the demands needed to support all learners. Low teacher efficacy is associated with high rates of attrition. As a result, districts throughout the United States struggle to retain the teachers they recruit and hire…
