Styrofoam-and-Velcro: An Alternative to Ball-and-Stick Models <sup> </sup>
For students learning biology at introductory levels, one of the most significant instructional barriers is their lack of preparation in chemistry. In upper-division college chemistry and biology courses, students employ ball-and-stick models in order to visualize molecular structures, but at the in...
