Around the world, on every continent, and in every country, children play. Though culturally contextualized, play is a global common childhood experience. There are cultural variations in children's play activities, and though play looks and sounds different across the world, there are also commonalities. Though scholars find it difficult to…

Computer programming provides a framework for interdisciplinary learning in sciences, arts and languages. However, increasing integration of programming in K--12 shows that the block-based and text-based dichotomy of programming environments does not reflect the spectrum of their affordance. Hence, educators are confronted with a fundamental…

Background: Since the 1990s, national standards have been developed in K-12 subject areas. National standards in health education were first released in 1995 with a second set released in 2007. A third edition, the "National Health Education Standards: Model Guidance for Curriculum" and Instruction was developed in 2022 under the…

The three articles in this dissertation explore how curriculum, instruction, and assessments should align with the vision for science learning outlined in the Framework for K-12 Science Education. Together, the papers demonstrate how curriculum, instruction, and assessment, when mutually supportive of each other, can foster a learning environment…

This study described the features of writing instruction in widely used kindergarten English Language Arts programs and examined their alignment with evidence-based, best-practice guidelines. Three popular curricula were selected for analyses: Reading Wonders, Journeys, and Reading Street. Our coding of teacher manuals focused on instructional…

In a study examining the efficacy of Heggerty's Bridge to Reading program during the 2023-2024 school year, LXD Research measured the program's impact on kindergarten and first-grade students' reading outcomes on the NWEA MAP Reading Fluency assessment. Results indicated that first graders using the program demonstrated significantly greater…

Climate change is an urgent global issue that requires concern and action among a climate literate citizenry. Early childhood climate change education (CCE) affords strong potential for developing this climate literate citizenry. Early childhood educators are critical for this endeavor, and their climate change perspectives, teaching practices,…

High-quality science assessments are multi-dimensional. They promote disciplinary practices, core ideas, cross-cutting concepts, and science sense-making. In this paper, we investigate the feasibility of using generative artificial intelligence (GenAI), specifically multimodal large language models (MLLMs), to annotate and provide improvement…

Investigators often rely on the proportion of correct responses in an assessment when describing the impact of early mathematics interventions on child outcomes. Here, we propose a shift in focus to the relative sophistication of problem-solving strategies and offer methodological guidance to researchers interested in working with strategies. We…

Preschool through third grade (P-3) alignment is regularly named as a key aspect of early childhood education and the transition to formal schooling. However, little is known about P-3 alignment in practice. Using data from 265 observations of math instruction in preschool, kindergarten, first-, and third-grade classrooms in New York City public…

This mixed-method study examined the balance of narrative and informational text instruction in alignment with Common Core State Standards (CCSS), and teachers' professional learning opportunities in elementary classrooms. Surveys were sent to teachers in one midwestern state, and audio recordings of literacy instruction were collected in one…

In recent years, the use of external proficiency-based tests to measure learners' language ability has increased significantly, in part thanks to the Seal of Biliteracy movement. However, there exists very limited research investigating the influence of such tests and their subsequent outcomes data on teachers' practices. As such, this study…

This paper considers the pedagogical collaborations between early childhood teachers in kindergarten (4 years) and the first year of school (5 years) in one Australian State. We report on a year-long project that brought these early childhood teachers together as we asked them to design STEM learning ecologies that would not only support new…

Comprehensive school health education (HE), despite its link to enhancing both student health and academic achievement, often faces barriers to effective implementation. As pedagogical strategies evolve to integrate traditional methods with technological innovations like artificial intelligence (AI), the adoption of innovation in HE preparation…

The purpose of this qualitative study is to investigate the significance of how pre-K and kindergarten teachers' perception and implementation of instruction prepares children for literacy in both grade levels. Three research questions guided the study: Are pre-K and kindergarten curricula aligned with implementing emergent literacy skills in…
