Our site has a large collection of assessment questions that can be assigned to students. These questions fall into three different categories. The assessments types pertain to:
1. statistics concepts typically found in an introductory statistics course in college or in an AP Statistics course at the high school level.
2. R programming concepts that allow students to become familiar with R statistical programming language.
3. Assessment items that integrate statistics and R concepts together.
Yes, we are currently building a problem bank of questions that can be used to create custom assignments.
Yes, once assignments have been created, they can easily be shared by teachers across the hall or across the globe. 
Students can be asked any of the following question types and the prevalence:
1. Numeric answer (~80%)
2. Multiple Choice
3. Check all that apply
4. Fill-in
5. Free Response
Virtually all questions found in our system have question specific hints associated with them. Thus, when a student is struggling with a problem, he or she has a chance to request help in the form of hints. Most questions have between 2 to 5 hints, and each hint progresses the student closer to the answer. The last hint is always the answer so that the student can move on to the next question.
Yes, our platform provides the option for teachers to assign both release and due dates for assignments.
Yes, late assignments are tracked in the teacher dashboard.
Questions that have answers that are numeric, multiple-choice, fill-in, or check-all-that-apply are worth 1 point each. For numeric answers, the students gets 1 point if he or she answers the question correctly on the first attempt. If the student fails to answer the question correctly, but answers the numeric question on the second or third attempt, 0.5 points is awarded. For multiple-choice, check-all-that-apply, and fill-in, students have only 1 attempt to get full credit. Finally, free response is graded 0, 1, 2, or 3 by the teacher.
Teachers must manually grade all the free response questions in the teacher dashboard section of the website. Each question can be scored 0, 1, 2, or 3.
Absolutely. We provide question specific help on calculating the answer using the TI-83/84 calculator.
No, currently we only provide support for these two platforms. However, if there is another platform that you feel that we should support, please let us know.
Yes, the dashboard provides information on the number of hints students use.
First, any time a student uses a hint, he or she automatically gets the question wrong, and their average goes down. Second, teachers can view how many hints are used by each student. Finally, teachers can control the delay between hints, in seconds, to prevent abuse of hints and to promote more active use of the information provided in the hints.
Yes. To encourage students to think through the hints provided, you can implement a timed delay, in seconds, between hints. In the teacher backend, this is located in the top right under settings.
Tutor mode is for meant more for formative assesssments while test mode is more for summative assessments. While using tutor mode, hints are available and the correctness of each answer is given. While using test mode, students are only told that their answer has been recorded, nothing more. In addition, during test mode, no hints are available.
A teacher’s dashboard is an integral component of KEY2STATS. The dashboard is a collection of reports and real-time interactive graphs that contains aggregate and individual student assessment data. This dashboard provides each teacher with the necessary information, in real time, to assess student learning of assigned problem sets. This information can then be used to modify teaching methods as well as classroom pace to help improve student learning.
