Troubleshooting i>clicker

In general, when you upload your i>clicker polling data back into Sakai, the experience will be seamless and won’t require further work. Although rare, there are a few possible discrepancies or errors that could occur with this process. The following scenarios describe situations that will result in an integrate discrepancy.

Your student has a clicker with the number scratched off.

  • Students may check inside the battery hub to see if their remotes have a "back-up" barcode. Remotes shipped Fall 2009 and later have this barcode that matches their remote ID. Simply remove the bottom battery and check.
  • If neither of the above options apply to your students, they may go to the Lakeshore bookstore to retrieve their ID. Please have them bring their remote, as they will be voting in person and then writing down the remote ID.

When a student tries to register in Sakai, s/he gets a message that the clicker is already registered.

Although the student gets the message that the clicker is already registered, in i>grader the student is not showing as registered with that clicker number. To resolve this, the instructor should make a list of the remote IDs that won't register and email them to sakai@luc.edu so the numbers can be manually reset by i>clicker. Once that has happened, the students who have those numbers will have to go back into Sakai and re-register.

You have found a clicker in your classroom; you want to return it, but you don’t know which student it belongs to.

Email sakai@luc.edu to find out which student registered the clicker.

Your student is not in your Sakai roster but is in your i>grader roster.

This will be a very rare occurrence. In order for this error to appear, you would have manually added a student to your roster file in your i>clicker course folder. The best way to avoid this error is to simply rely on your Sakai roster as the most up-to-date resource for your most current roster file.

The uploaded scores (from i>clicker) are lower than those previously recorded in Sakai for an individual student or students.

This does not generally require any work by you—it is simply an alert. For example, you may want to give Jane Doe a higher i>clicker score for a session on 9/12/2013 because she helped you facilitate a demonstration in class. i>grader currently does not allow you to change scores for individual students. Instead, you can make the individual change manually within Sakai. If you later re-upload (intentionally or accidentally) the 9/12/2013 i>clicker scores back into Sakai and the score for Jane Doe is lower in i>grader than in Sakai, our application won’t override your manual adjustment. The report will simply let you know the discrepancy exists. If you wish to change an individual score to overwrite the Sakai score (i.e. lower Jane Doe’s score again), you will need to make this change within Sakai, not i>grader. Note that while lower i>grader scores will not override adjustments you made in your Sakai Gradebook, higher i>grader scores will overwrite lower Sakai grades without a discrepancy notice.

You are exporting i>clicker scores for a student who has registered, voted in class, but then subsequently dropped the course (and is therefore no longer in Sakai).

Again, the best way to avoid this error is to rely on your Sakai roster as the most up-to-date resource for your most current roster file. When you synchronize the most current version of your Sakai roster with i>grader, you may be left with voting logs from a Remote ID that are not associated with a student (if that student came to class, voted, then dropped the class). In this case, you may delete the voting logs for that Remote ID from within i>grader by clicking on the Remote ID and selecting the “remove” option.

TIP: You can save the Transmission Report in Excel (.xls), Plain Text (.txt), or comma separated (.csv) format for later review. You can also view any previous Transmission Reports for the same course. Click the Export Options menu at the top of the report and select your desired file format. A confirmation message appears stating that the file was written to your course folder. Click OK to close the message window.
