Development and Validation of an Authentic-Based Competency Assessment Rubric for Secondary School Multimedia Production Subject

Abstract

The use of rubric to support students’ competencies gradings is long being applauded in vocational education. However, the current assessment method in secondary school vocational education seems to be inauthentic, individualistic and outdated. The assessment criteria are in a checklist form and far from meeting the industrial’s needs. Students were assessed based on their ability to perform a certain set of skills and disregarding their affective skills such as communication, presentation and working in team. A self-developed authentic-based competency assessment rubric for a vocational subject in secondary school was developed in lieu to the latter. The rubric instruments and criteria were developed based on extensive literature reviews on students’ skills evaluation in vocational education settings. Findings from the reviews have led to selection of operational terms and formulation of rubric’s instruments. The rubric is expected to measure students’ competencies or skills in on four domains: Teamwork, Skills, Knowledge and Presentation. Each of the domain contains five assessment items with five level of ratings. There are three stages involved for the development and validation of the rubric. First, the development of instruments, second, the content validation by subject matter experts and finally, subject matter experts’ scores validation using Lawshe (1975) method. Content Validity Ratio (CVR) and Content Validity Index (CVI) were used to validate the instrument and measuring its reliability. The overall analyses show that the self-made authentic-based competency assessment instrument is reliable. The findings are important for researchers, teachers, assessors and policy makers especially taking rubric as an option for grading competency assessment for secondary school’s vocational education. There are possibilities into exploring the assessment criteria into meeting the current industrial’s needs and global standards.
