Researchers who have demonstrated that it is possible to improve students' spatial visualization skills, which are key for success in some STEM courses and careers, are testing their curriculum with community college students.
The first 95 students who completed the non-credit spatial skills course at Del Mar College, McHenry County College, and Tidewater Community College earned on average, one full letter grade higher (a grade of B) in the introductory STEM course they took than students who qualified for the spatial skills booster, but opted not to take it (and averaged a grade of C).
