The research samples consist of seventy-two students who take "Computer Application" course of the second grade in a vocational high school. The students use the web-based portfolio assessment system for creating their portfolio, emulating peers' portfolio, and performing peer-assessments. The results show that the assessment scores between different students (on the same one portfolio) have no adequate consistence (reliability between assessors). The assessment scores of two-third students (each student on different portfolios) have no adequate consistence (reliability within an assessor). The scores of peer-assessments and teacher assessment have no adequate consistence (external object association validity). The consistence between peer-assessments and test scores is low, meaning the web-based portfolio peer-assessments do not demonstrate learning achievement (external object association validity). In short, web-based portfolio peer-assessment have no adequate reliability and validity.學習歷程檔案網路化學習歷程檔案網路化檔案評量同儕互評PortfolioWeb-based portfolioWeb-based portfolio assessmentPeer-assessment
