This research investigates the Models of eighth-grade students in Turkey pertaining to magnets and magnetic interactions, while also examining the consistency of these models within themselves. Additionally, a comparative assessment is conducted by comparing the current data with data collected from eighth-grade students a decade earlier. The…

Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

This quasi-experimental research aimed to examine if and to what extent the adaptation of the 4/3/2 technique and self-assessment contributes to the improvement of students' speaking fluency. 24 ninth graders ranging from 11 to 13 years old were separated randomly into control and experimental groups, each having 12 participants. The data were…

Recognizing and using mathematical structure are key components of mathematical reasoning. The authors believe that one productive way to support students' use of structure is by identifying opportunities to address structure in the context of what teachers are already doing, rather than developing additional tasks or new curriculum materials. The…

Emperor penguins, the largest of all the penguin species, attain heights of nearly four feet and weigh up to 99 pounds. Many students are not motivated to learn mathematics when textbook examples contain largely nonexistent contexts or when the math is not used to solve significant problems found in real life. This article's project explores how…

Since 1973, the National Assessment of Educational Progress (NAEP) has gathered information about student achievement in mathematics. Results of these periodic assessments, produced in print and web-based formats, provide valuable information to a wide variety of audiences. They inform citizens about the nature of students' comprehension of the…

Numeracy in schools is becoming an increasingly important part of mathematics learning and teaching. This is because educators want students to engage with mathematical concepts more deeply, use mathematics to make sense of their environment and make decisions that are based on the analysis of mathematical information. In order to be numerate,…

This comprehensive volume offers a snapshot profile of every public school district in the United States serving 1,500 or more students and provides pertinent evaluative and demographic statistics necessary to evaluate educational programs nationwide. This edition includes profiles on 5,797 school districts in the United States, representing 90%…

Through the Common Core State Standards (CCSS) Initiative, states and territories have collaborated in the development of a common core of standards in English Language Arts and mathematics for grades kindergarten through twelve that are now being adopted by states. Designed not only for the purpose of providing strong, shared expectations, the…

Manufacturers often claim that their particular toothbrush design is better than the competitors, but is it? As a result, engineers must consider the economic issues involved with selling the products they create, as well as their functionality: to produce the best possible toothbrush regardless of cost, or the toothbrush that will sell the most,…

Alison Stephen, who has wrestled for many years with the challenges of teaching emotional and controversial history within a multiethnic school setting, relished the opportunity to link her school's teaching of the Holocaust with a comparative study of other genocides. As she reports, her aim was to not create a hierarchy of suffering or…

This article illustrates the use of comparison as an instructional approach that can help students develop and use a variety of problem-solving strategies and approaches in the mathematics classroom. Through comparison of solution strategies, students deliberately consider the similarities and differences among methods and how different strategies…

Professional development--formal in-service training to upgrade the content knowledge and pedagogical skills of teachers--is widely viewed as an important means of improving teaching and learning. While many interventions "include" professional development, professional development was the central intervention of the two recent research and…

In the past, nativists opposed immigration, period. The sharp distinction between "legal" and "illegal" immigrants emerged fairly recently, according to immigration historian David Reimers, a professor of history at New York University. "Basically, by the mid-90s 'legal' immigration was no longer an issue," he says.…
