Educational assessments, from kindergarden to 12th grade (K-12) to licensure, have a long, well-documented history of oppression and marginalization. In this paper, we (the authors) ask the field of educational assessment/measurement to actively disrupt the White supremacist and racist logics that fuel this marginalization and re-orient itself…

A group of eighth-graders was presented with a two-day lab exploring graph theory as an enrichment experience. With the school's winter break looming, students were weary of solving linear equations, and this topic was intended to inject some new life into the classroom. In addition to learning about a completely new topic, they would be exposed…

Instructional coaching, informed by observation tools that measure teachers' practices, has been effective in improving teaching quality in early learning programs. However, existing measurement tools limit teachers' abilities to implement this type of instructional coaching at scale. To address this challenge, a team at SRI Education, along with…

This paper frames children's mathematics as mathematics. Specifically, it draws upon our knowledge of children's mathematics and applies it to understanding the prime number theorem. Elementary school arithmetic emphasizes two principal operations: addition and multiplication. Through their units coordination activity, children construct two…

Assessments are one of the most important--and often misunderstood--elements of education. In most cases, tests are administered by the state as well as by districts and schools. Assessments at each of these levels have distinct purposes, yield different information, and are part of a powerful, coordinated approach to improving student outcomes.…

As a follow-up to their article, "Emojis and Their Place in the Mathematics Classroom" (EJ1358586), the authors examine how emojis can be used as bridging representations to support student understanding of proof and algebra in upper primary school. They take a problem from reSolve, Level 3, (AAMT, 2020), look at it from the perspective…

By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Proof, as a central and integral part of mathematics, is an essential component of mathematical education and is considered as the basic procedure for revealing the truth of mathematical propositions and for teaching productive reasoning as part of human civilization. Is there therefore room for conjectures in mathematics? In this paper after…

Young learners' language aptitude is understudied due to a lack of tests covering this period of life. Young learners, in contrast with adults, are still acquiring their L1. Consequently, a language-dependent aptitude test should be carefully designed for it to be valid. An additional challenge is found when the young learners who are to take the…

Over a 6-year period, a sociolinguistic and sociocultural project was undertaken by Alaska Native expert educators and linguists (aka the Yup'ik Expert Group) from the Yup'ik community in the Lower Kuskokwim School District, Central Alaska. The native experts developed their own culturally sustainable, valid, and reliable Kindergarten through…

The population of young language minority (LM) students is rapidly growing worldwide due to global migration and immigration trends. The increasing representation of young LM students in school settings creates high demand for the language assessment of LM students in order to meet the needs of stakeholders, such as governments and language…

Explore the impact technology has on mathematical identity and agency when students use mathematical action technology to engage in cycles of proof and support case-based reasoning. This article showcases a mathematics task used in a fourth-grade class that allowed students to develop their conceptual understanding of division. The authors…

This article describes the development and initial testing of the "Elementary Literacy Coach Self-Efficacy Survey", a new instrument designed and created to assess literacy coaches' efficacy for coaching-specific tasks. A synthesis of literature on literacy coaching tasks and experts in the coaching field were used to craft the…

When a Year 7 student physically reacted to a prompt of another student by anxiously drumming the desk with his ruler, exclaiming "uuuuhh", the initial thought of the observing researcher, Laura, was: "this is an interesting account". This started a reflective journey of first applying robust research methodologies to the…

Teachers need to assess their students' current level of mathematical understanding to provide appropriate interventions for students who are struggling. Several school districts in Georgia currently use two assessments for this purpose--the Global Strategy Stage (GloSS) and the Individual Knowledge Assessment of Number (IKAN). The IKAN is…
