HOW RELIABLE IS SELF-ASSESSMENT?: INVESTIGATING THAI EFL UNDERGRADUATES€™ SELF-ASSESSMENT PERFORMANCE IN FORMATIVE CLASSROOM WRITING ASSESSMENT : LANGUAGE TESTING AND ASSESSMENT

While self-assessment can promote learners’ self-learning strategies necessary for learning progression and language development in an ongoing classroom (Knoch & Macqueen, 2017), questions have been raised concerning the quality and utility of students' self-assessment outcomes (Brown, Andrade, & Chen, 2015). This paper investigated self-assessment performance of Thai EFL undergraduates at three ability levels (N = 68) vis-à-vis five teachers’ assessment performance in ongoing writing classrooms, where they all applied the same rating scale to formatively assess writing essays. Self-rating and teacher-rating scores were analysed and compared through ANOVA and correlation statistics. Results revealed that overall students were able to self-estimate their ability to a certain extent but appeared to significantly overestimate their ability. Generally, higher-ability students demonstrated more consistent ratings whereas lower-ability students performed less consistent ratings vis-à-vis teachers’ ratings. Implications are also discussed concerning the design and implementation of self-assessment for students with different abilities in formative classroom assessment.
