This study investigates washback effects on the learning portfolio of university students. The washback effects were explored using a questionnaire and interviews with two groups. The results were as follows. First, although learning portfolios have no effects on English learning purpose, other areas (English learning activities, language skills and language knowledge, and perception of assessment system) experienced partial washback effects. Second, there were significant changes and differentiation in each language skill(reading, writing and listening) and significant partial changes in English knowledge (vocabulary). Third, overall, learners preferred the traditional result-oriented assessment system to a process-oriented assessment system like a learning portfolio, despite that two groups have no differences in perception of assessment systems between the process-oriented assessment and product-oriented assessment system. Fourth, learners showed mixed opinions in the interviews: embarrassment from unfamiliar learning portfolio assessments and expectation of novelty. That is, although learners obtained their passive learning attitudes from the pre-existing instruction methods, they appreciated the merits and importance of learning portfolio assessment. Therefore, this study suggests that the washback effects of learning portfolio can be implemented for university students carefully.

An, Soyoung. 2018. “An Analysis of University Students' English-Learning Motivation Change through Portfolio Assessment”. The Sociolinguistic Journal of Korea 26(1). 251~275. This study aims to analyze university students' English-learning motivation through making a learning portfolio. I conducted an experiment to know whether motivation could be changed by different assessment systems, a result-oriented assessment and a process-oriented assessment. First, there were no statistically significant differences in English-learning motivation between the two groups subject to a result-oriented assessment and a process-oriented assessment by independent T-test. Second, the variable “attitudes toward learning English” significantly changed when students created a learning portfolio by paired T-test. Students showed their preferences for studying English through an authentic learning portfolio method. Therefore, even though the new assessment system such as a portfolio assessment brings us innovation, the assessment system had a partial impact on students' English-learning motivation.

This study explored the effectiveness and second language (L2) writers' perceptions of process-oriented writing, using portfolio-basedinstruction in a secondary English class at general school settings. The participants were 110 high school students enrolled in a private independent school in Gyeonggi. They learned to produce a four-paragraph-English-essay based on the process-oriented writing methodology, keeping a portfolio note for the entire semester. The instructor was a bilingual teacher of English whose native language is Korean. The 17 weeks' records written in the portfolio note were analyzed to portray whether the approaches enhanced overall performance and understandings about essay-writing. Findings revealed that the participants were satisfied with this approach and improved their writing skills using portfolio-based- instruction. For the sake of implementing the new assessment appropriately at public school settings, further studies are suggested to develop how to enhance classroom environment in order to increase the degree of learner-satisfaction in the essay-writing classes.

This study was to inspect how the portfolio assessment in physical education classes affects the learning attitude and the improvement of motor skills. The experimental group of 40 students utilized the portfolio assessment and the control group of 40 students were tested with a traditional assessment. A test paper on learning attitude and a measure on assessment of motor skills was estimated of reliability and validity. After a vaulting horse-rolling instructions were practiced 11 sessions for 4 weeks that the experimental group were tested with portfolio assessment. The control group were tested with traditional assessment. Each group took a posttest about learning attitude and motor skills. The collected data through the posttest were analyzed with t-test. The findings of this study could be listed as follows; First, the learning attitude of experimental group using the portfolio assessment was better than the control group, and the difference was significant statistically. Second, the motor skills of experimental group using the portfolio assessment were better than the control group, and the difference was significant statistically.
