Certificate Course Description

In this course, you will learn how to create a novel type of tutor called example-tracing tutors, that can be built without programming using the Cognitive Tutor Authoring Tools (CTAT). You will be able to create a tutor interface through drag-and-drop techniques and then demonstrate the problem-solving behaviors to be tutored.

Creating example-tracing tutors has been shown to be 4–8 times as cost-effective as estimates for ITS development from the literature. Since 2009, CTAT and its associated learning management system, the Tutorshop, have been extended and have been used for both research and real-world instruction. As evidence that example-tracing tutors are an effective and mature ITS paradigm, CTAT-built tutors have been used by approximately 44,000 students and account for 40% of the data sets in DataShop by 2016. These tutors support a variety of pedagogical approaches, beyond step-based problem solving, including collaborative learning, educational games, and guided invention activities. CTAT and other ITS authoring tools illustrate that non-programmer approaches to building ITS are viable and useful and will likely play a key role in making ITS widespread.

Our team hosts office hours for all courses over Zoom on the 2nd and 4th Wednesday of each month, 10:00 AM – 11:00 AM EDT/EST (4:00 PM – 5:00 PM CAT). On 2nd Wednesdays, Dr. Ken Koedinger, who is the Director of the Masters of Educational Technology and Applied Learning Sciences (METALS) program, will be available. On 4th Wednesdays, you will have the opportunity to speak with our learning engineers.

Module 1: Intelligent Tutor Design Principles
  • Describe the most common instructional design principles for Cognitive Tutors
  • Define ITS instructional features and design space as described by VanLehn
  • Describe knowledge component modeling

 

Module 2: Example Tracing Basics
  • Set up a CTAT development environment
  • Use the HTML editor or coding to create a CTAT layout
  • Use the behavior graph editor to create a solution/error path
  • Explain the relation between using an example-tracing tutor and paths in a behavior graph
  • Attach step-specific information to a behavior graph
  • Use formulas in a behavior graph
  • Assignment 1: Create an example-tracing tutor for dose calculation in veterinary medicine*

 

Module 3: Advanced Functions of Example Tracing

  • Mass produce an example tracing tutor
  • Deploy a CTAT tutor in an LMS
  • Use the behavior graph editor to create a solution/error path
  • Assignment 2: Extend your example-tracing tutor from Assignment 1 using advanced forms of ITS functionality*

 

Module 4: Course Project

At the end of the course, you’ll have an opportunity to do a little project in two stages. In first part, we will provide you feedback and help you choose a problem that is nuanced enough to take advantage of example-tracing capabilities and an estimate of time required. Then you will create an example-tracing tutor for the second part of your project targeting that problem and submit it along with a report.

That will provide you with a nice experience to apply the fundamentals you will learn in the modules to a larger, more authentic, context. It will be graded by the instructor and you will receive personalized feedback.

 

* Each assignment will be graded by the instructor and you will receive personalized feedback along with sample solution

None

Researchers, developers, product/UX designers, instructional designers, and teachers who want to create intelligent tutors. Anyone interested in edtech.
