    3: It is possible to incorporate the use of clickers into a LON-CAPA course.  Students must register their clicker IDs in the Preferences (see \ref{Clicker_Registration}) in order to incorporate clicker data into the course.  Instructors can upload scores to a problem using the clicker ID information provided by the students.  Follow the steps below to upload clicker data to count as credit in your LON-CAPA course.
    4: 
    5: \begin{enumerate}
    6: 
    7: \item Optionally register your own clicker in your Preferences (see \ref{Clicker_Registration}).
    8: 
    9: \item Add a Score Upload Form to your course from the Course Editor.  You can
   10: have multiple clicker questions in one lecture, but only one Score Upload
   11: Form for each lecture.
   12: 
   13: \item Display your clicker questions in class.  Example, use PowerPoint.
   14: 
   15: \item Have students use the clicker to answer the questions. Optionally answer the question correctly with your own clicker.
   16: 
   17: If you use your own clicker to answer the questions, you can later use that data to have the ``correct answers determined by instructor(s)''
   18: 
   19: \item Take the clicker datafile and upload it to LON-CAPA:
   20:   \begin{enumerate}
   21:   \item Navigate to the Score Upload Form
   22:   \item Click the Problem Grades menu item
   23:   \item Choose the option to process clicker
   24:   \item Browse and Upload the clicker files
   25:   \item Choose the clicker brand (example, i$>$clicker)
   26:   \item Choose the appropriate option to award points
   27:      \begin{itemize}
   28:      \item Award points just for participation
   29:      \item Correctness determined from response by course personnel
   30:        (This option assumes you registered your own clicker and
   31:        answered the question.)
   32:      \item Correctness determined from response with clicker ID(s)
   33:        (If you answered the question with an unregistered clicker,
   34:        enter that clicker's ID here.)
   35:      \item Correctness determined from given list of answers
   36:        (If you didn't answer the question with a clicker, define
   37:        correct answer here.)
   38:      \end{itemize}
   39:   \item Define what percentage of the question weight students get for
   40:       getting the question correct or incorrect. Your data file may 
   41:       have multiple questions. Say, you award 70\% for incorrect and
   42:       100\% for correct, and the student has three wrong and two 
   43:       correct answers, you get (3*70\%+2*100\%)/5=82\%.  The student is
   44:       then awarded 82\% of the weight of the Score Upload form.
   45:   \item Upload file.  There may be correction steps you need to to go
   46:       through letting you choose users for unregistered clickers, 
   47:       etc..  You will need to deal with these steps to finalize the
   48:       upload and scoring.
