Toward Precision on Evaluation: Hierarchical Weighting-Based Assessment on Implementation of Outcome-Based Curriculum

Abstract

Assessing learning outcomes is essential for measuring student achievement and enhancing educational effectiveness. However, traditional assessment methods often struggle to capture the complexity of diverse competencies, leading to gaps in evaluation and improvement. Outcome-based education (OBE) represents a shift from conventional paradigms by emphasizing the attainment of predefined learning objectives at multiple levels, including student, course, and program outcomes. This study introduces a hierarchical weighting-based assessment framework designed to evaluate learning outcomes comprehensively. The framework employs a three-tier weighting system that assigns differentiated weights to various assessment elements. Using a development research model, this approach enables a nuanced and holistic evaluation of student performance. The methodology involved needs analysis, assessment modeling, practical implementation of the framework, and case study analysis to demonstrate its effectiveness. The User Experience Questionnaire (UEQ) was administered to 225 users to evaluate the system's usability and emotional impact. Results show that the proposed framework offers a more accurate representation of student achievement, aligning closely with intended learning outcomes and performance indicators, and effectively distinguishing varied competencies across diverse assessments. The findings highlight its potential scalability across educational institutions seeking to refine assessment practices. Additionally, this framework presents a promising strategy to enhance the precision, inclusivity, and engagement of educational evaluation systems.
