What does it look like to "understand" operations with fractions? The Common Core State Standards for Mathematics (CCSSM) uses the term "understand" when describing expectations for students' knowledge related to each of the fraction operations within grades 4 through 6 (CCSSI 2010). Furthermore, CCSSM elaborates that…

In light of emerging technologies prompting new avenues for teaching and learning, students are positioned to "create" to learn, with video production being an important process for literacy development. There is a growing need for innovative instructional practices in reading and writing that are aligned with student interests and the activities…

Despite a decline in popularity within US society, posters continue to hold a prominent place within middle and high school science classrooms. Teachers' demand is satisfied by governmental and non-profit science organizations that produce and disseminate posters as tangible products resulting from their research, and instruments to communicate…

Good learning experiences ask students to investigate and make sense of the world. While there are many ways to do this, K-12 curriculum has traditionally skewed toward reading and writing to interpret and express students' sense-making. But there is another way. Infographics represent data and ideas visually, in pictures, engaging more parts of…

This article describes a representation for percent that can help students deepen their understanding of the proportional nature of percent in its applications. (Contains 4 figures.)

How can cognitive load in visual displays of computer simulations be optimized? Middle-school chemistry students (N = 257) learned with a simulation of the ideal gas law. Visual complexity was manipulated by separating the display of the simulations in two screens (low complexity) or presenting all information on one screen (high complexity). The…

The use of picture books as supplementary material for middle level classrooms is becoming more common. Picture books are being created specifically to address the needs and interests of middle school students. Society is becoming more visually oriented and the visual format of picture books appeals to adolescents, who today are exposed to various…

This article describes a hands-on activity in which students convert decimals to fractions, measure, make scale drawings, use algebraic formulas, and use visualization to construct a three-dimensional physical model of a portion of the seafloor. In the process, they learn about sound, speed, and ocean exploration. (Contains 2 figures.)

This paper summarizes a research project conducted to investigate the strategies developed by middle school students to solve a route-finding problem using Arc View GIS software. Three different types of route-finding strategies were identified. Some students were visual route-finders and used a highly visual strategy; others were logical route…

The purpose of this research was to determine whether there were significant differences in male or female middle-school students' ability to appropriately convey the emotions of happiness, sadness, anger, and fear while singing musical passages within the context of four treatment situations. Four treatment methodologies were designed to identify…

This article describes a collaboration between a university professor and a sixth-grade teacher who teamed to introduce algebra using a visual approach. The project began with a study of qualitative graphs, moved on to quantitative graphs, then introduced tables of values and finally concentrated on equations. (Contains 12 figures.)
