Creating Electronic Portfolio Rubrics for General Education Course Assessments in Thailand

Abstract

While researchers have introduced and integrated electronic portfolios (e-portfolios) into general education classrooms at Srinakharinwirot University, Thailand, some aspects of workloads and assessments remain unclear to both instructors and students. When evaluating academic performance using e-portfolios, instructors must grade students based on learning outcomes according to the learning objectives and students’ goals. The use of such assessments requires a shift toward realistic and consistent evidence, practice, and reflection. Successfully assessing outcomes and learning processes entails instructors and learners being able to identify and understand all evaluated aspects. Thus far, instructors and learners have practiced and agreed upon two types of e-portfolio rubrics for general education course assessments: an analytic five core skills learning process rubric and an annotated e-portfolio assessment rubric. This study employs indices of item-objective congruence (IOC), item discrimination power, Cronbach’s alpha reliability coefficients, and correlations as analytical tools to determine the efficiency, confidence, and relationship of each item in an annotated e-portfolio assessment rubric.
