5.1 Creating answers for your misconceptions


The misconception answers work the same way as question answers and expectation answers. Just like your expectation answers, you may have several misconceptions per question. 

When designing your misconception answers you should be sure to create an answer key that specifically covers a misconception. The pre-loaded canned expressions and rules will explain to the user and/or student agent that their recent input is covering a misconception. 

Name & Keys
  • 1. Name your answer. This is for your use. Name each one of your answers so you can better organize your tutoring pack. 
  • 2. Provide a semantic answer using regular expressions. This is what the AutoTutor Lite system will compare your student's input to. This is very similar to the semantic answers used in both the Self-Reflection assessment type and the Tutoring Assessment type. In the "Keys" box, you should include the essential words that would be needed to fully answer the question. Ideally, you will input these answer keys as regular expressions. The AutoTutor Lite system still takes advantage of LSA cosine similarity when comparing student input to answers, but the use of regular expressions helps make up for some of cosine similarity's shortcomings (i.e, differentiating between positive and negative answers). Because cosine similarity is still used to evaluate student input, the your SKO's semantic engine configuration is still important to consider. 
    • After a question is asked and the user provides input, that input will be compared to each of the keys for each of your question answers and misconception answers. If the student input has a high overlap with a misconception a misconception -> hint -> prompt sequence will begin in an effort to correct the student misconception.  
  • 3. Select which agent you would like to provide feedback for the student input. You can select either "Tutor" or "Student" as your agent. For misconceptions, it is often better to associate the misconception text with a student agent. This allows the student agent to express the same misconception as the user. The student agent will be corrected directly, and the user will be corrected indirectly. 
  • 4. Select the "answer type". The dropdown menu allows you to select an "answer type". The answer types that are available are based on the rules that have been pre-loaded into your ASAT SKO. 
  • 5. Select your answer threshold. This threshold determines what percentage of answer key coverage is necessary for the student input to be considered as answering the question. For example, if we set the threshold for the "Ideal Answer" to .9, then the student input would need to match (or have semantic overlap with) 90% of the answer key. The Tutor or Student agent (depending on who you selected) will then speak what is written in the Text & Speech tab. 
Text & Speech

The Text & Speech tab under "Answers" is where the spoken and written answer should be placed. This will be read by whoever you selected in the Agent drop down menu.
