Spatial Visualization - Optional Extra Credit

You may choose to take this [Spatial Visualization Evaluation.](/ef105-2019-08/PSVT/instructions_2.php)for extra credit. - You may decide that taking the evaluation and the associated modules is helpful for you if: - you are interested in 3D modeling, or are in an engineering discipline in which 3D modeling is an important skill, - you want to improve your skill in related areas of calculus and chemistry - you are just interested in developing this skill for its own sake ## Extra Credit Grading - If you earn a score of 18 or higher on the initial Spatial Visualization Test, that test score will be weighted as an additional quiz grade with 18 considered full credit. Scores above 18 will contribute to additional extra credit. - If you earn a score of 17 or lower on the initial Spatial Visualization Test, your test score will still be weighted as an additional quiz grade with 18 considered full credit and, - you may choose to leave it at that, or - you may work through the provided ungraded practice modules and then take the Spatial Visualization Final Test which will open on November 25. The higher of your two scores will be taken as an extra quiz grade, again with 18 considered to be 100 points. ### When to Expect Grades to be Updated You should see an individual score for each test under the "Spatial Visualization" section on the gradesheet, but the calculation of the extra credit quiz grade does not happen automatically. We will calculate these scores at the end of each day through December 4, so expect any changes to appear by the day after you complete the test.

What is spatial visualization? Spatial visualization is the ability to mentally manipulate 2-dimensional and 3-dimensional figures.

Why is spatial visualization important? Spatial visualization is considered to be one of the seven human intelligences. Research has shown that well-developed 3-D spatial skills are critical to success in STEM fields. Just as with any of the other human intelligences, there are some individuals who naturally possess excellent spatial abilities and some whose spatial skills are not as well developed. The important thing to remember about spatial skills is that they are skills and can be developed through practice, just like any other skill.

Are other schools teaching spatial visualization? Yes, the University of Tennessee is part of a consortium that is implementing key strategies to improve undergraduate retention in engineering. Further information on spatial visualization can be found here.

What do my results mean? The research shows that students who score 18 or higher (at least 60%) are generally deemed to have the necessary spatial visualization skills to be successful in engineering, math, physics and chemistry courses. Students who score below 18 (less than 60%) would greatly benefit from some skill development. What the research also tells us is that individuals can dramatically improve their skills in a short amount of time and that skill improvement has been shown to improve persistence in engineering.

  • 0-17 - Scores of 17 or lower indicate the need for additional practice in order to be successful in calculus, chemistry and engineering courses. You will be required to complete the spatial visulaization modules to earn the full 10 points for the Spatial Visualizaton component of your EF 105 final grade..
  • 18 - A score of 18 indicates that you have the minimum skill level for success in calculus, chemistry and engineering courses but might CONSIDER participating in the spatial visualization modules.
  • 19-30 - A score of 19 or higher indicates that you currently have the spatial visualization skills to be successful in your calculus, chemistry and engineering courses.

Spatial Visualization Modules:

Welcome to the first module for spatial visualization!! Let's take care of some housekeeping notes before you get started:

  • Please complete each module in the following order: videos then practice and finally feedback.
  • No additional extra credit is associated with the modules, they are for you to help improve your score on the Spatial Visualization Final Test, if you wish.
    Isometric views
    Orthographic projections
    Inclined and Curved Surfaces
    Rotations - Single Axis and Two Axes
