Abstract
Undergraduate students often find it difficult to manage curriculum. Engineering
courses often require student to solve assignments and take in-class exams throughout the
semester that include solving complex practical applications which can be challenging,
one of the reasons being the time constraints. Additionally, the use of computers to solve
the real-world problems during in-class exams is demanding due to its set-up cost and
accommodation of large number of students at the same time. This thesis describes the
study of a large engineering class using a non-conventional testing method. Student
performance was evaluated using online testing modules with a stringent passing
criterion and the tests could be taken multiple times. The questions for each testing
attempt was pulled from a huge database so that students received a new question every
time. Student survey results indicated that most favored the online testing assessment
method. Our results show that students learned from their mistakes and their performance
improved by taking the test multiple times. We compared the performance of students on
the traditional assessment who took the course in the previous semester with the
performance of student on the online testing module. Our analysis shows that the students
earned better grades using the online tests than the students in their in-class exams. The
online assessment method could be useful in the large engineering courses that are
focused on formula-based curriculum.
