Lots of New Statistics Data in the Quiz Generator

Faculty and TAs ask frequently for more information about the data captured in student exams and quizzes in CoursePlus. Having pre-computed statistics helps them make decisions about what is working (and what is not) in this kind of assessment.

We've added a number of new statistics to the Quiz Generator in CoursePlus. Here's a brief tour:

First, basic statistics about student performance on a quiz are now shown on the main "All Responses and Grades" page as soon as students start taking a quiz, and also appear on the main quiz overview page once the quiz is closed to students.

Basic statistics about student performance on a quiz

Next, statistics about student performance on each individual question in a quiz are now available. If you view the "Responses to Questions" report on the "Statistics" tab for a quiz, you will see the following information:

  • Number of students who answered the question
  • Number of students who skipped the question
  • Percentage of students who received full credit on the question
  • Percentage of students who received partial credit on the question
  • Percentage of students who received no credit for the question

This appears in addition to already existing data on the percentage of students who selected each different possible answer to the question. This data is also shown for essay and fill-in-the-blank questions, fulfilling a long-standing facuty and TA request.

Finally, there's an entirely new tab of statistical data for each quiz: the discrimination value tab:

Discrimination Value tab location

Briefly, this tab shows you information about the difficulty of each question in the quiz. Two pieces of information about each question are shown:

  1. The difficulty index of the question on a scale of 0-1 as measured by the percentage of students who got full credit for the question.
  2. The discrimination value for the question. The discrimination value refers to how well an individual question in an assessment differentiates between high and low scorers. The discrimination value can be in the range of -1 to 1. If the majority of students whose overall performance on the quiz was in the top 50% of all scores answered the question correctly, the value will be closer to 1. If the majority of students whose overall performance on the quiz was in the bottom 50% of all scores answered the question correctly, the value will be closer to -1.

Discrimination value report table

In addition to simply showing the difficulty and discrimination values for each question in the quiz, the report also highlights the following:

  • The questions answered correctly by the most students
  • The questions answered correctly by the fewest number of students
  • Questions with a negative discrimination value
  • Questions with a discrimination value less than .2, which is generally considered the cutoff for question discrimination desirability.

You can download the source data which splits students into low and high scorers used in calculating the discrimination values in Excel format.

We hope that all this additional data helps you create better quizzes and exams!

Better Reminders for Students to Sign in to Class

A growing number of classes on campus use the CoursePlus Attendance Tracker tool to have students mark themselves as present at an individual class session. We've improved the tool over the past year, including adding the option of requiring students to enter a 4-digit PIN given out in class when they sign in. 

In April, 2017, we asked faculty and TAs who use the tool for feedback on how to improve it. A very common theme was figuring out a way to remind students that they needed to sign in during the class. Faculty now have the option of providing reminders to students that they need to sign in to a given class session using the Attendance Tracker tool.

Reminders are turned on by default for all class sessions which are set up to require student sign in. You can have reminders turned on for some sessions, but not others, as you see fit.

If reminders are turned on for a given session, students get three different reminders to sign in:

  1. A reminder to sign in is included in the Daily Course Notifications email which students receive each day.
  2. A reminder to sign in is included in their "My Calendar" tab.
  3. An alert box is placed at the top of their "My Courses" page which reminds them that they need to sign in to a class if they have not already done so.

In each case, a link to the course home page of the appropriate course, where they must click the "Sign In" button, is provided.

We hope that this multi-pronged approach to reminding students to sign in to class sessions will significantly improve the rate at which students remember to sign in!

Reminder: IE 11 is No Longer Supported for CoursePlus

As we start the first term of the new academic year, we wanted to remind everyone that Internet Explorer Edge is the only version of Internet Explorer supported in CoursePlus. This is stated on the terms of service page for CoursePlus.

Internet Explorer Edge only works with Windows 10 — now the preferred version of Windows for the Johns Hopkins University. If you are running Windows 8 or Windows 7, you need to use Chrome or Firefox to access CoursePlus. Using Internet Explorer 11 to access CoursePlus is possible, but it will result in numerous problems. Chrome or Firefox are much better (and more frequently updated) alternatives to Internet Explorer 11.
