This study aims to explore how a research-informed product, a hypothetical learning trajectory (HLT), was implemented by a group of Shanghai teachers in mathematics classrooms and promoted by a researcher through a Chinese lesson study. The instruction informed by the HLT served as a boundary object to promote conversations between the researcher…

This study delves into the intricate academic journeys of three former Black teen mothers who surmounted significant socio-cultural and economic barriers to attain higher education degrees, encompassing bachelor's, master's, and doctoral levels. The study involved a qualitative narrative inquiry analysis approach using in-depth interviews to…

Development of the cardinality principle, an understanding that the last number-word recited in counting a collection of items specifies the number of items in that collection, is a critical milestone in developing a concept of number. Researchers in early number development have endeavored to theorize its development. Here we critique two widely…

This single case study concerns an 11-year-old girl, Agata, who recently moved to a rural community in the United States from the Philippines. Agata is profoundly deaf, has had no access to amplification, and has had very limited access to language and formal school. The journey through the next year, including the COVID-19 pandemic, saw Agata's…

This dissertation explored the perspectives of stakeholders within a university-level Spanish Heritage Language (SHL) program in Arizona, focusing on their language ideologies and critical language education efforts. The study, rooted in Critical Language Awareness (CLA) and Culturally Sustaining Pedagogy (CSP) frameworks, challenges deficit-based…

This study examined the learning trajectory of five US humanities teachers when navigating learning to teach the difficult history of school desegregation within a context of a six-month inquiry-based professional development. The research questions were: What do teachers frame as problems when teaching difficult histories? How do they…

China has witnessed significant growth in the number of children affected by internal rural-urban migration. These children predominantly suffer from educational inequalities. Most relevant studies have primarily attributed such inequalities to "hukou"-based exclusion. However, the active agency of rural migrant parents in their…

This study analyzed the trajectories of five twice-exceptional students during their first year of higher education. The aim was to identify the personal and contextual barriers they faced and the enabling factors available to them. Based on a qualitative approach and a multiple-case design, narrative interviews were conducted with the…

Using neurodiversity as our theoretical framework, rather than a deficit or medical model, we analyze the narratives of five dyslexic research mathematicians to find common strengths and challenges for dyslexic thinkers at the highest level of mathematics. We report on 3 themes: (1) highly visual and intuitive ways of mathematical thinking; (2)…

This research aimed to generate a learning trajectory in an introduction to early mathematics, precisely to measure learning using educational games and Realistic Mathematics Education (RME) and to describe young children's curiosity in learning early mathematics. Children need to have an understanding to take a measurement and use a learning…

This paper presents insights from a broader study on doctoral students' educational and professional trajectories, with a particular focus on female international doctoral students in the United States. It explores how these women navigate their career paths while balancing the dual responsibilities of academic demands and motherhood. Drawing on…

There is a significant amount of data available about students and their learning activities in many educational systems today. However, these datasets are frequently spread across several different digital services, making it challenging to use them strategically. In addition, there are no established standards for collecting, processing,…

Theory is an important element of literacy research. Research designs are informed by theories that explain what literacy is, how it develops, and how it should be taught and evaluated. Sociocultural theories emphasize the socially situated nature of literacies engagement and practices, whereas cognitive theories emphasize the underlying skills…

This paper shares findings from the study of a learning sequence designed to support prospective elementary teachers (PTs) in identifying evidence of conceptual understanding and procedural fluency. Conceptual understanding and procedural fluency are widely recognized as important to teaching and learning mathematics, and identifying evidence of…

We argue in this paper that there is currently no adequate theoretical framework or model that spans the twelve odd year trajectory from non-reader to proficient reader, nor addresses fine-grain skill acquisition, mastery and integration. The target construct itself, reading proficiency, as often operationalized as an endpoint of formal secondary…
