The Role of Materials in Teaching Listening Strategies in Computer-based and Text-based Classes: EFL Learners' Listening Comprehension and Cognitive Load in Focus

Listening effectively in a foreign language presents many challenges for students. The aims of this convergent mixed methods study were two-fold. First, to determine whether teaching listening strategies through materials tailored to apply principles related to decreasing Cognitive Load (CL) could help learners improve their L2 listening comprehension. Second, whether using such materials could reduce learners' cognitive load. In doing so, two modes of material presentation (computer-based and text-based) were selected. Eighty-eight TEFL bachelor students in three intact classes were randomly assigned to three treatment conditions: Strategy-Based Cognitive-Load-Decreasing Computer-Based Material (SB-CLD-CBM), Strategy-Based Cognitive-Load-Decreasing Text-Based Material (SB-CLD-TBM), and Strategy-Based Non-Cognitive-Load Decreasing Conventional Learning Material (SB-NCLD-CLM), and received relevant instructions. A general proficiency test was used to examine participants' language proficiency. A listening pretest and posttest, a listening achievement test, and a cognitive load questionnaire were used to collect data in the quantitative phase. A reflection paper, including two questions about students' perceptions administered during the treatment, was used to gather qualitative data. The One-way Analysis of Variance (ANOVA) and Multivariate Analysis of Variance (MANOVA) showed that CLD-CBM and CLD-TBM outperformed the NCLD-CLM in listening comprehension and experienced lower cognitive load. However, no significant difference was found between the experimental groups. The findings are valuable for teachers and materials developers, suggesting they should include Cognitive Load Theory principles and strategy instruction when designing learning materials and instructional approaches.
