This article describes the two types of reasoning in fraction conceptions that students often use, "gap" and "missing piece," and one that the authors aspire their students to reach, "residual." Each of these types of reasoning are underpinned by a different conception of fractions. Students who use "gap…

The Common Core State Standards for Mathematical Practice asks students to look for and make use of structure. Hence, mathematics teacher educators need to prepare teachers to support students' structural reasoning. In this article, we present tasks and rubrics designed and validated to characterize teachers' structural reasoning for the purposes…

Graduating from high school is an important step toward becoming a successful adult. It is evidence that one has met the standards set by the public school system. Standards-Based Reform has been pursued since the 1980s and culminated in the development of the Common Core State Standards that were implemented by most states between 2011 and 2015.…

Understanding and supporting students' development of graph literacy is important. We studied how aspects of graph literacy might be supported (or hindered) in middle school by analyzing the content in textbooks. Specifically, we conducted a content analysis of tasks involving two-dimensional Cartesian graphs presented in grade 6-8 US textbooks.…

The purpose of this study was to examine the effects of extended vocabulary instruction on the expressive vocabulary of two third-grade students with vocabulary deficits. According to the Common Core State Standards Initiative (n.d.), students in third grade should be able to determine the meaning of unknown and multiple-meaning words and phrases…

Political agendas and political attention often change based on media attention and business influence, ultimately impacting policies. Elementary and secondary education policies have evolved to improve academic rigor and increase global competitiveness. Common Core State Standards (CCSS) were established based on state-level elementary and…

Understanding negative numbers can be challenging for many students, as these concepts may seem less tangible than counting objects, which are commonly represented by positive numbers. In addition, the multiplication of two negative numbers resulting in a positive might appear inconsistent and puzzling to young learners who are used to seeing the…

This guide includes 8 elementary school level lessons, inspired by topics from "Ocean Odyssey," a film for IMAX and other Giant Screen theaters. Host-narrated by oceanographer Sylvia Earle, "Ocean Odyssey" is an immersive film following a mother and calf humpback whale on their migration from the tropics to Antarctica.…

"Geometry--Do" is a textbook about plane geometry. It will be divided into two volumes, "Geometry without Multiplication: White through Red Belt," and "Geometry with Multiplication: Blue through Black Belt. "The white- and yellow-belt chapters are neutral geometry; the remainder of "Volume One" and all of…

While the Common Core State Standards for Mathematical Practice are a focal point of K-12 mathematics education, there is limited research examining how future teachers' (e.g., undergraduate students, teacher candidates) develop their conceptions of these standards. We investigate how opportunities within a mathematics-focused bridge course within…

Classroom assessment research in the United States has shifted away from the examination of teacher-made tests, but such tests are still widely used and have an enormous impact on students' educational experiences. Given the major shifts in educational policy in the United States, including the widespread adoption of the Common Core State…

Educators have, to this point, largely viewed the Common Core State Standards (CCSS) and Response to Intervention (RtI) as important but unrelated initiatives. This view is problematic because it fails to acknowledge the potential for RtI to support readers who struggle to meet sophisticated standards and because it fails to attend to ways in…

Many Career and technical education (CTE) teachers concern themselves with the practical application of skills in their course content. Common Core State Standards (CCSS) have increased the emphasis on disciplinary literacy in courses making every teacher a literacy teacher requiring every teacher to teach students to be literate in their content…

In this investigation, the reading performance of Texas Grade 4 Emergent Bilingual and non-Emergent Bilingual students was compared by their enrollment in Title I, Part A schools. Data were obtained from the Texas Education Agency Public Education Information Management System for all Grade 4 Emergent Bilingual and non-Emergent Bilingual students…

As a growing number of K-12 school districts and the Common Core State Standards (CCSS) require educators to blend educational technology into the curriculum, teachers struggle with effective integration practices. Short-term professional development alone fails to support teachers with helpful approaches. To achieve success, educators need…
