The mean can be interpreted as a fair-share value and as a balance point. Standards documents, including Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010), suggest focusing on both interpretations. In this article, the authors propose a sequence of five activities to help students develop these understandings of the mean, and they…

Pill bugs, also called roly-polies, are small terrestrial isopods that are abundant in temperate areas throughout the world. Because they are engaging, harmless, and easily collected, they provide an excellent opportunity for children to learn about invertebrate body parts, behaviors, and information processing. This column includes activities…

This study examines the evolution of 11 prospective teachers' understanding of mathematical modeling through the implementation of a modeling module within a curriculum course in a secondary teacher preparation program. While the prospective teachers had not previously taken a course on mathematical modeling, they will be expected to include…

Over the past few years, students by the thousands have refused to take their state's standardized tests. This "opt-out" phenomenon has prompted debate in state legislatures and in Washington, putting states at risk of losing Title I funds. Advocates describe opt-out as a grassroots movement of parents concerned about overtesting,…

The Odd Shape Out task was an open-ended problem that engaged students in comparing shapes based on their properties. Four teachers submitted the work of 116 students from across the country. This article compares various student's responses to the task. The problem allowed for differentiation, as shown by the many different ways that students…

"Energy" is a term often used in everyday language. Even young children associate energy with the food they eat, feeling tired after playing soccer, or when asked to turn the lights off to save light energy. However, they may not have the scientific conceptual understanding of energy at this age. Teaching energy and matter could be…

For two decades the International Literacy Association (ILA) has published the "What's Hot, What's Not in Literacy Survey." In the last five years, the hottest topics featured on the lists have largely been connected to the English Language Arts Common Core State Standards (ELA CCSS)--a publication produced by the National Governors…

Secondary teachers nationwide are encouraged by the Common Core State Standards and recent research to enact disciplinary literacy instruction. However, little is known about how teachers make sense of teaching disciplinary literacy skills to adolescents. To what extent might adolescents still need the kinds of foundational support provided by…

When the editors of "Literacy Research and Instruction" invited Donna Alvermann and Glenn Jackson to respond to "Beyond the Common Core: Examining 20 Years of Literacy Priorities and Their Impact on Struggling Readers," they both instantly recognized the strengths and limitations in their collaboration. In the strengths corner,…

During the past few years, several of the authors have incorporated student problem posing as a regular instructional feature in their classrooms. When they offer their students the opportunity to construct their own problems, particularly during the course of an entire school year, they create many novel tasks. Student-created tasks not only…

The noise in generating an agreed upon definition of instructional leadership that extends beyond theory to the practice of principals has been almost deafening in the last few decades. Many emphasize the need for the role of the principal to adapt to meet the demands of leadership that maximizes student achievement, but lack the specificity to…

Since adopting the Common Core State Standards (CCSS) in 2010, California has given districts significant flexibility in how they support teachers in implementing the standards. This flexibility, along with vastly differing local and regional contexts, has resulted in a wide variety of district-level approaches to training teachers in content…

Now in its fourth edition and with extensive updated research, "Later Language Development" addresses the development of spoken and written language from Kindergarten through early adulthood. The information in this text is aligned to the Common Core State Standards and describes the critical connection between language development and…

We analyzed 52 middle school mathematics lessons from multiple states and curriculum contexts to understand how teachers were enacting the CCSSM. The teachers stated that all of the lessons were CCSSM-aligned. We categorized curriculum materials according to two approaches, with one approach associated with curriculum programs funded by NSF and…

With a national reputation for high standards and a rigorous assessment system, Massachusetts now faces a critical transition. The Massachusetts Board of Elementary and Secondary Education's (BESE) December 2015 decision to develop a new state assessment (Next-Generation MCAS) brought with it the opportunity to improve the 2011 state standards for…
