Portfolio Assessment as a Window into Reading Development

Abstract These days the use of portfolio assessment is very popular. If it is believed that students at all levels should be doing more than studying for tests; teachers should be doing more than teaching to tests; students should take a more active role in the learning process; and, then the portfolio assessment is an idea worth exploring.. The aim of this study was to introduce portfolio assessment into our classrooms for improving students' reading comprehension. To achieve this goal, the researcher adopted the quasi-experimental design comprising the pretest-treatment-posttest paradigm. Two classes were selected as the experimental and control groups from Cambridge Institute in Sari. They were 52 female students. The only difference between the two groups was integrating portfolio into learning for the experimental group. The result of this study indicated that portfolio assessment did not have a significant effect on the students' reading skill.
