There are presently many limitations on how multiple choice exams can be created and graded. It is difficult and very time consuming to design questions for examinations that test a range of concepts and application of those concepts.

Exams are normally written manually as a document using a word processor (Word, StarOffice ...). For privacy reasons using web applications and cloud applications is strongly discouraged or prohibited. This makes it very difficult to build a library of questions that can be searched, revised and reused. Searching through old exams for questions that can be revised and reused is VERY time consuming.

Multiple choice exam question libraries from publishers of textbooks are often delivered as a word processor file full of multiple formats, unclear questions, and even questions with incorrect answers. Copyright laws also limit the exam authors ability to provide answer keys that publish the questions from the publishers question library and provide answers. This limits an instructors ability provide their students feedback to help them understand what they missed on the exam.

Our current system of grading is based on recording answers on bubble sheets, having a scanning service scan those sheets and return the number of correct questions for each student and a statistical analysis of those results. It is also possible to obtain data indicating the answer provided by every student to every question, but this is raw data and does not include the statistical analysis.

Using bubble sheets has many problems. Students often use ink, make the sheets unreadable from excessive erasures, or incorrectly fill in personal information in the bubble portion of the sheet. This means that there are always a significant number of sheets that require manual data entry/correction. This is a time consuming process that could be partially automated. Errors like correcting an incorrect student number based on the student name could be partially automated.

Using the provided scanning service and bubble sheets it is not possible to give different weights to different questions on the exam without reprocessing raw data yourself. The statistical analysis is often useful in identifying problem questions on the exam. However, resubmission to the scanning service is the only way to repeat the statistical analysis after removing a problem question. Problem question would include those that were accidentally assigned an incorrect answer, that had unanticipated multiple interpretations, or that were unclear/unfair for other reasons. Resubmission to the scanning service requires special permissions and is slow and usually not possible in the time between a final examination and the release of final grades. This often means manual revision of student grades to remove a question from the exam after it has been scanned.

To address all these problems we want to include a MULTIPLE CHOICE MODULE that includes multiple choice exam question library, a multiple choice exam builder, and a multiple choice grader with statistical analysis of exam results in the Streamlined Grading System. This module must

1. Include a library of multiple choice questions that can be searched based on keywords in the question. The library could initially be empty but would grow as more exams were built using the system

2. Include a clear and easy to use interface for entering multiple choice questions with 2 6 possible answers and adding them to the library and the multiple choice exam being written

3. Include a clear and easy to use interface to select questions from the library and include them in a multiple choice exam being written

4. Include a way to input raw scanned results that are provided by the scanning service to the system

5. Calculate the exam scores for each student

6. Include a way to apply different weights to different questions when student exam scores are calculated

7. Include an ability to redo the type of statistical analysis done by the scanning service after a question has been removed or its weight has been altered.

8. Include a tool to help the user correct student numbers that have been incorrectly entered or not entered
