OUTCOME-BASED EDUCATION AND ACADEMIC ACHIEVEMENT: A QUANTITATIVE ANALYSIS OF UNDERGRADUATE STUDENTS

Abstract

Outcome-Based Education (OBE) is a student-centered approach that emphasizes clearly defined learning outcomes and competencies. Unlike traditional content-based instruction, it focuses on what learners are expected to achieve upon completion of a course or program. Despite its increasing adoption in higher education, empirical evidence on its impact on academic achievement, particularly in developing contexts, remains limited. This study therefore examined the relationship between OBE practices and undergraduate students’ academic achievement. A quantitative cross-sectional survey design was employed. The population comprised undergraduate students from public and private universities, and a stratified random sample of 350 students was selected. Data were collected using a validated 25-item Likert-scale questionnaire covering five OBE dimensions: learning outcomes clarity, assessment alignment, teaching effectiveness, student engagement, and feedback mechanisms. Content validity was ensured through expert review, while construct validity was established using Exploratory Factor Analysis (factor loadings = 0.61–0.87). The instrument demonstrated excellent reliability (Cronbach’s α = 0.91). Data were analyzed using SPSS through descriptive statistics, Pearson correlation, and multiple regression analysis at a 0.05 significance level. Findings revealed a high level of agreement regarding OBE implementation (M = 4.12, SD = 0.58). A significant positive relationship was found between OBE and academic achievement (r = .68, p < .001). Regression results showed that OBE significantly predicted academic achievement (β = .61, p < .001), explaining 42% of the variance (R² = .42). Among OBE dimensions, learning outcomes clarity and assessment alignment were the strongest predictors of achievement. The study concludes that OBE significantly enhances undergraduate academic performance by promoting clear learning expectations, aligned assessment practices, and student-centered learning environments. These findings support constructive alignment theory and confirm the educational value of OBE in higher education.
