The second purpose is to examine the application effects o f progressive self- and peer-assessment procedures designed with the Web-SPA system. An evaluative study with 76 ninth-grade students finds that the students display the tendency of being more objective in their self-assessment scores after the progressive self- and peer-assessment activities; there is significant consistency between the results of the students' self- and peer-assessment and that of the teachers; and the quality of the students' works improved after the assessment activities.
