Learning Curve Monitor Progress Report

The Learning Curve Monitor keeps track of the student of how the student is doing on on a particular problem compared to the average for all of the problems he/she has worked on.

A. Tracking Incorrect Answers

The number and type of incorrect answers tracked by the Learning Curve Monitor are:

1. Unanticipated Incorrect Answers: Those that are within 1% - 10% [10x], or off by more than 10% [>10%].

2. Unit Labels: The answer was not accepted because of an incorrect or missing unit label. [Unit]

3. Non-unit Labels: The answer does not include the correct non-unit label. [Label]

4. Anticipated Incorrect Answers: The incorrect answer was anticipatedby the author of the problem. [AIA:A …E, etc.]
   

No incorrect answers were recorded by theLearning Curve Monitor for student working on this mole conversion problem. (Note: these examples are only for illustration, and do not report actual student use.) As the student works more and more problems, we should expect to see a decrease in the number of incorrect answers.

B. Tracking the Kind of Help Used

The amount and type of help requested from the Personal Tutor tracked by the Learning Curve Monitor are:

1. Use of ShowMe help is recorded if you responded "Yes" to the ShowMe message question; or if you clicked on the Solve button.

2. Hints: This category will be recorded:
   • View a ShowMe message, but do not allow the Personal Tutor to insert a term in the setup, and exit with a "No" response.

   • Use the Units or the Cancel Units button.

   • Invert a ratio.

3. Factors Help: This category will be recorded if you use the Factors button:
   • To generate a conversion factor from the unit labels.

   • To calculate the molar mass from a chemical formula
     

Note: For the student working on this problem, no help was recorded. As the student works more and more problems, we should expect to see a decrease in the amount of help needed.

C. Tracking Time

The Learning Curve Monitor will keep track of the time spent by the student working on the problem:

1. Completed: The time spent on the problem will be recorded as "Completed" once you’re a checked- answer is accepted as "correct". (Note: You can still work on the problem - checking for alternative answers or solutions. The timer, or other types of tracking by the Learning Curve Monitor will be turned off.)

2. Incomplete: The time spent on the problem will be recorded as "Incomplete" if you exit [Close] before entering a correct answer.
   

D. Identifying Problem Areas

As a student moves on to work on the solution to more complex problems, he or she might find that some kinds of errors made in earlier "simpler" problems may repeat themselves. For example, a student working on a reaction stoichiometric problem may miscalculate a molar mass needed in the setup. You can identify these problem areas by comparing the Learning Curve Monitor reports for "All Problem Types" with other types of problems.

Compare the types of incorrect answers entered for the 79 problems for "All Problem Types" above (A) to the 12 mole conversion problems and 14 density calculation problems worked earlier.

E. Printing LCM Statistics and Graphs

The student may print out a record of their progress as a table or graphical summary. (To print all three categories, check the All check box.)

• LCM Statistics: Click on the Print Stats button to print out the LCM statistical table.

• LCM Graph: Click on the Print Graph button to print out the LCM graph shown at the bottom of the Learning Curve Monitor window.
