摘要:Online assessment has been increasingly popular in the tertiary education setting nowadays and has had significant changes to the process of assessment. Several studies have been conducted on online assessment, particularly on online peer assessment and found that it benefits students in teaching, learning and assessment. This paper will discuss the result of a study conducted in a Chemical Engineering class which uses online peer assessment as one of the tools to conduct assessment. The objective of this study was to investigate the effectiveness of online peer assessment to students’ learning from the students’ perspective. The perspective of the students was under study because they are the ones who are going through the process, thus, the effectiveness of the assessment to their learning can only be known if the information is obtained from them. The students were divided in small groups and asked to conduct online peer assessment using any free online survey tools. Each group had to conduct 2 or 3 cycles of peer assessment to ensure validity of the rating. The peer rating was used to produce individual marks for group work. At the end of the semester, the students were asked to write a reflection on the effectiveness of online peer assessment in their learning process of the course. The result of this study found that students have positive perspectives on the effectiveness of this assessment. This will be further discussed in the paper. In addition, pedagogical implications will also be discussed on the use of such online peer assessment in student’s learning task.
