vancing problem-solving research and curriculum development, specifically mathematical<br />

modeling and data modeling at the primary level.<br />

Forward to the Past?<br />

The beginning <strong>of</strong> this chapter is a disparaging reflecti<strong>on</strong> <strong>of</strong> the research, namely<br />

classroom teaching <strong>of</strong> problem solving strategies and heuristics does little to improve<br />

students’ problem-solving abilities. But this is a piece <strong>on</strong> “problem solving<br />

for the 21 st century” and is optimistic for the future. It makes a str<strong>on</strong>g case for mathematical<br />

modeling in the elementary grades, proposing problem solving to develop<br />

c<strong>on</strong>ceptual development.<br />

There are caveats that need to be remembered. Twenty-five years ago, Bank<br />

Street College <strong>of</strong> Educati<strong>on</strong> created a thirteen episodic educati<strong>on</strong>al video program<br />

called The Voyage <strong>of</strong> the Mimi. This was an interdisciplinary problem-solving unit<br />

for middle grade students, first aired <strong>on</strong> Public Broadcasting Service (PBS), then<br />

marketed by Sunburst S<strong>of</strong>tware. Throughout the voyage, an oceanographer, marine<br />

biologist, teenage assistants, a deaf college student, and the captain’s grands<strong>on</strong><br />

c<strong>on</strong>struct hypotheses, make measurements, collect and analyze data. Students were<br />

shown video scenarios and then asked to solve various problem situati<strong>on</strong>s (counting<br />

whales or procuring enough fresh water for the trip) that occurred <strong>on</strong> board<br />

the Mimi. The Voyage <strong>of</strong> the Mimi was a slickly-produced televisi<strong>on</strong> series—now<br />

remembered as a young Ben Affleck’s first starring role as the captain’s grands<strong>on</strong><br />

(http://www.bankstreetcorner.com/voyages_<strong>of</strong>_mimi.shtml).<br />

In 1990, the Cogniti<strong>on</strong> and Technology Group at Vanderbilt University created<br />

the Jasper Woodbury Problem Solving Series videodiscs. The 12 interdisciplinary<br />

videodisc adventures were also for middle-grade students. Each adventure was designed<br />

like a detective novel, ending in a complex challenge. The videodisc series<br />

was to research the relati<strong>on</strong>ships between cogniti<strong>on</strong>, learning and anchored instructi<strong>on</strong><br />

(i.e., situated instructi<strong>on</strong> in the c<strong>on</strong>text <strong>of</strong> informati<strong>on</strong>-rich envir<strong>on</strong>ments to<br />

encourage students to pose and solve complex, realistic problems) (http://peabody.<br />

vanderbilt.edu/projects/funded/jasper/).<br />

Both <strong>of</strong> the above instructi<strong>on</strong>al programs were alternative mathematical modeling<br />

approaches to traditi<strong>on</strong>al teaching <strong>of</strong> problem solving. Each had good problemsolving<br />

results. Neither had significant standard mathematics test results above, or<br />

below, the normal student populati<strong>on</strong>.<br />

Neither programs are used today in schools. Why? No single instructi<strong>on</strong>al<br />

method directly affects learning (Zollman in press). Specifically, more attenti<strong>on</strong><br />

must be paid to the classroom teacher, who is the single most important influence<br />

<strong>on</strong> student achievement and motivati<strong>on</strong> (Darling-Harm<strong>on</strong> 1999). Indeed, improving<br />

teaching quality is the “mechanism for improving students’ academic performance”<br />

(Wenglinsky 2000, p. 9). The cost, instructi<strong>on</strong> time required, expertise needed, implementati<strong>on</strong><br />

training, plus many more variables (social, cognitive, and political)<br />

pressure the classroom teacher “to stay the course” in problem-solving instructi<strong>on</strong>.
