Query: O.D.E.S. : An Online Dynamic Examination System based on a CMS Wordpress
  plugin   This paper describes the online dynamic examination application plugin named
O.D.E.S., developed according to the open source software philosophy, where the
CMS Wordpress is used as programmers/coders are given the potential to develop
applications from scratch with safety and ease. In ODES application there
exists two types of users: admin/teacher and student. The admin/teacher can
create/edit/delete/view questions, categories of questions and examination
papers. The questions are divided in two types, multiple choice questions
(including true/false) and long answer questions (essays). The teacher can
create exams choosing the number of questions and the types of questions that
exist in the pool of questions that are previously created. The selection is
done randomly by the application and the teacher just determines the total
number of both multiple choice or long answer questions as well as the
importance (weight) of each one of them (including negative grades also). The
student takes the random generated exam and receives his/hers grades. The
grades of the multiple choice questions are done automatically, whereas for the
long answer questions the teacher is responsible to put grades on. After the
completion of the exam the teacher can view the student's final score via the
control panel or a report.
