Studies Using ASSISTments with Heffernan Authorship(n=22)

These are the studies that Heffernan has authored.
There are also 5 studies done with ASSISTments that Heffernan did not author. Those 

ASSISTments has been used in over 20 published randomized controlled experiments to investigate different ways to improve student learning.  Some are listed below.  By clicking on the name of the paper you will be able to see the conditions that were compared.  Each page has a link at the bottom to the full-text version of the published paper.

  1. Comparing experimental conditions that give feedback with control conditions that represent "business as usual" where students don't get feedback until the next day. 
    1. Estimating the effect of web-based homework. With Univ. of Illinois (UIC)
    2. Does immediate feedback while doing homework improve learning. 
    3. Improving learning from homework using intelligent tutoring systems. With West Virginia University
  2. Showing that ASSISTments Closes Achievement Gaps (between with lower achieving student and higher achieving students).
    1. ASSISTments attempt to personalize learning led to better learning
  3. Comparing hints versus step-by-step scaffolding questions, versus solution, versus worked examples.
    1. Feedback during web-based homework: the role of hints  
    2. What level of tutor interaction is best?
    3. Scaffolding vs. hints 
    4. Is it better to give hints or let students ask?
    5. What features of hints matter?  With Carnegie Mellon, Columbia, and University of Pennsylvania  
  4. Comparing worked examples to step-by-step feedback
    1. Are worked examples an effective feedback mechanism during problem solving?
    2. Two experiments related to tutored problem solving vs. “pure”: worked examples. With Seton Hall University, Carnegie Mellon and Albert Einstein College of Medicine
    3. A novel techniques to analyze experiments that have no posttest.
  5. Comparing different videos intended for motivational benefits
    1. Adding teacher-created motivational video to an intelligent tutoring systemWith University of Notre Dame
    2. Mayer's Multimedia Principles at use in K12
    3. Giving students a choice causes more learning 
  6. Comparing connecting with parents versus a control
    1. Homework completion rates increased when parents were connected.
  7. Comparing different instructional approaches
    1. Comparing discovery learning with direct instruction replicating (and extending) the famous Klahr and Nigam result.  
    2. Blocking vs. Interleaving: Does skill pattern matter? With Carleton College
    3. Does asking students to self-report their confidence in affect their performance? With Harvard University
  8. Comparing the Automatic Reassessment and Relearning System(ARRS) feature with other options.
    1. Comparing Automatic Reassessment and Relearning System with one time Mastery Learning. With Univ. of Illinois (UIC)
    2. Comparing Different Schedules of Spacing Schedules. 
    3. Comparing ARRS with an adaptive ARRS version called PASS for  Personalized Spacing Schedules
