Purpose The purpose of this paper is to examine early career teachers’ Socialized Knowledge Communities (SKCs) as they relate to the pursuit of mathematics knowledge and teaching. The authors investigate Pinterest, a living data archive, as an opportunity to view teachers’ sense-making and construction of instructional resources. Through this lens, the authors examine how teachers form and share mathematical meaning individually and collectively through professional collaboration. Design/methodology/approach This work characterizes teachers’ curation of mathematical resources both in the kinds of mathematics teachers are choosing and the quality therein. Finally, the authors examine through epistemic network analysis how teachers are sense-making through a statistical approach to identifying their organization of mathematics curation by typology and cognitive process demand. Findings Results show that sampled teachers predominantly curate instructional resources that require students to perform standard algorithm and represent mathematics relationships in visualization within Pinterest. Additionally, the authors find the resources curated by teachers have lower cognitive demand. Finally, epistemic networks show teachers make connections among instructional resources with particular types as well as with different levels of cognitive demand as they sense-make their curated curriculum. In particular, difference in teachers’ internal consideration of the quality of tasks is associated with their years of experience. Originality/value Twenty-first century classrooms and teachers engage frequently in curation of instructional resources online. The work contributes to an emergent understanding of teachers’ professional engagement in virtual spaces by characterizing the instructional resources being accessed, shared, and diffused. Understanding the nature of the content permeating teachers’ SKCs is essential to increase teachers’ professional capital in the digital age.

Social media and other virtual resource pools (VRPs) have emerged as spaces wherein teachers can connect with other educators and acquire curriculum materials. Though teachers actively engage online, seeking and accessing alternative curriculum materials, little is known about how these efforts may impact culturally relevant education for students with diverse languages, literacies, and cultural practices in the classrooms. Situated in Ladson-Billings's work on culturally relevant pedagogy, this chapter outlines a framework for selecting and evaluating culturally relevant curriculum materials and applies it in a prominent virtual space: Teachers Pay Teachers (TpT). We find that there is a lack of opportunity for deep engagement in culturally relevant education as evidenced in resources found on TpT. This finding suggests unique challenges as well as opportunities for educators and researchers to leverage resources and knowledge from the cloud to the classroom. We conclude with a discussion of these challenges and opportunities from the perspectives of four groups of actors: (1) the creators and curators of curriculum materials, (2) the prosumers who proactively seek out resources and leverage VRPs, (3) the educators who commit to preparing or guiding teachers using VRPs, and (4) the researchers who study the virtual space for education quality and equity.

Genetics has become increasingly important in everyday life, a fact that is reflected in state and national science education standards. This study examines the relationship between 474 fifth graders' understandings of the core ideas of inheritance of traits and variation of traits. A confirmatory factor analysis, supplemented with qualitative analyses of students’ responses, revealed a relationship between these concepts and contributed evidence about the nature of students' challenges in learning these ideas. While most students demonstrated some normative ideas, many struggled to explain variation of traits as resulting from equal inheritance of genetic information from two parents. Instead, they focused on generational patterns of visible traits or on the influence of nongenetic factors. Deepening understanding of young students' heredity‐related thinking can improve preparation of older students for learning advanced genetics‐related ideas.

Educators who are committed to teaching STEAM in their classes and programs will be inspired and encouraged by the capabilities for multidisciplinary instruction and project based learning offered by an emerging pedagogy known as Maker Education. While making was previously thought of as STEM-focused, it can easily be integrated across all subjects. Maker Ed's Resource Library has a section on Projects and Learning Approaches, which includes many cross-curricular project ideas that expand this model of education from STEM to STEAM and beyond.
