Managing Cognitive Load in Task-Based Learning: Effects on Language Retention among 4th Year BSEd English Students at Bulacan State University - Sarmiento Campus

Task-Based Learning (TBL) has emerged as a highly effective pedagogical approach in language education, promoting authentic learning experiences through meaningful tasks. However, its complexity can impose substantial cognitive demands, potentially hindering language retention if cognitive load is not effectively managed. Cognitive load management strategies, such as task segmentation, scaffolding, and cognitive pauses, are designed to optimize learners’ mental resources and enhance retention. This study investigated how managing cognitive load within TBL impacts language retention among 4th-year BSEd English students at Bulacan State University – Sarmiento Campus. The study adopted an Explanatory Sequential Mixed Methods Design. In the quantitative phase, data were collected from 40 purposely selected students using Likert-scale survey questionnaires measuring perceived cognitive load, effectiveness of cognitive load management strategies, and language retention outcomes. Descriptive statistics (frequency, mean, standard deviation) and Spearman Rank-Order Correlation were applied to analyze the data. The qualitative phase involved collecting open-ended responses, which were examined using Collaizi’s Thematic Analysis with descriptive coding to identify patterns in student experiences. Findings revealed that 57.5% of students experienced high intrinsic cognitive load due to conceptually difficult tasks and complex sentence structures, while 50% struggled with grammar and vocabulary. Extraneous load was primarily linked to unclear instructions (47.5%) and disorganized materials (40%). Despite these challenges, 67.5% connected tasks to prior learning, and 62.5% actively applied retention strategies, indicating strong germane cognitive load. Scaffolding emerged as the most effective strategy (45%), followed by task segmentation (35%) and cognitive pauses (20%). Correlation analysis showed a strong positive relationship between effective cognitive load management and improved language retention. Qualitative findings highlighted themes of instructional clarity, real-life relevance of tasks, and the positive role of structured pacing in reducing overload. The study concludes that managing cognitive load in TBL significantly enhances language retention by balancing task complexity with strategic instructional support. Scaffolding and task segmentation were particularly effective in reducing intrinsic load, while cognitive pauses facilitated reflection and consolidation. These findings underscore the importance of intentional cognitive load management in designing language learning tasks, providing valuable implications for instructional strategy and curriculum development in higher education language programs.
