Dr. Aaron Wangberg's use of 3-D manipulatives in Multivariable Calculus were highlighted in the Winona Post:
With three-dimensional physical models, students at Winona State University (WSU) are learning multivariable calculus in a new fashion that involves drawing on the surfaces to help identify and work with different mathematical concepts before formally learning about them. The homegrown models have been shared with institutions throughout the U.S. as well.
Aaron Wangberg is a professor of mathematics at WSU who collaborated with students and engineering department faculty members on the making of the models and has used them to help students learn multivariable, or three-dimensional, calculus. The surfaces are dry erasable and large enough for multiple students to use as a common workspace on which to draw as they work through math problems and interpret what factors such as the height and the slope mean, Wangberg explained. ... continued
