  1. Using Diagnostic Tests to Evaluate Student Understanding Presented by Glenn Wagner

  2. Evaluating Student Understanding Why Bother… • What do your students know about fundamental physics concepts? • Is your instruction developing understanding of fundamental physics concepts?

  3. Force Concept Inventory (FCI) • Developed in 1992 (Hestenes, Halloun, Swackhammer) • Designed to test understanding for conceptual understanding in Newtonian physics • Tested extensively for validity and reliability • Includes ‘distractors’ to elicit pre-Newtonian thinking (e.g. heavier objects fall faster than lighter objects)

  4. How to Administer a Diagnostic Test • Begin with a pre-test before instruction (this gives a base-line of their initial understanding) • After instruction, give the same test again, post-test (how much learning did they gain in understanding?)

  5. We can extract two quantities… 1) Raw post scores (simply the final mark) 2) % gain in understanding % gain = (% posttest score) – (% pretest score) (100 – % pretest score)

  6. Let’s Play!!! Let’s complete the Force Concept Inventory

  7. Interpreting the Results Hestenes and Halloun say…. • 60% is the Newtonian ‘threshold’ where students have barely begun using Newtonian concepts coherently • 85% is the Newtonian Mastery threshold where students at this score or above are ‘confirmed Newtonian thinkers’

  8. Interpreting the % gain

  9. Mechanics Baseline Test (MBT) • Designed to test for the most basic concepts in mechanics • Use as a post-test only • Scores are expected to be lower than FCI since it is more difficult • FCI and MBT fit well together and give a broad snapshot of student understanding in Newtonian mechanics

  10. Diagnostic Test for Understanding Graphs in Kinematics (TUGK) • This diagnostic focusses on 3 fundamental areas: Slope of d-t graph gives velocity Slope of v-t graph gives acceleration Area under v-t graph gives displacement

  11. Try This…. • Apply FCI as a post test this June to your students (SPH 4U) • Apply FCI as a pre-test this September and post-test in January
