摘要：Learning outcomes is one of the important factors
to measure student achievement during the learning process.
Today’s learning is more focused on problem-solving and
reasoning to existing problems than an ordinary problem. Most
exams have been directed to analysis questions for students to
think and synthesize. As such is troublesome for most students,
they are not ready to answer the question, thus, their answers
almost similar to their friends. This implies that the teacher has
tried to guide students to work professionally and originally.
However, the Teacher facing difficulty assessing student’s work,
especially if the assignments are conducted online without faceto-face
instructions/discussions. To bridge such a gap, the teacher
needs a method or algorithm to measure their rank to encourage
students making an original answer. This research provides a
solution in calculating students' ranks based on the similarity
score of the essay answers. Pagerank is a ranking algorithm used
by Google, this algorithm utilizes a Markov matrix that contains
the direction of similarity score for each student. These scores are
computed by the power method until converging. Rank is
displayed to the teacher to review the similarity level of students'
answers. As such is presented a line chart in which the x-axis
refers to the students and the y-axis depicts the level of similarity.
Ranking computation in Matlab produces an Eigen vector which
acts as the rank measure. The higher the rank, the more similar
is their answers to others. Hence, students with high ranks to
work their answers more seriously ensure their original thoughts.
In conclusion, the similarity score matrix using the PageRank
algorithm can contribute to the teacher in providing peer
motivation and encouraging student’s internal motivation by
presenting the ranked-answers presentation.
