Beyond the Product: The Effect of Strategy-based Instruction on EFL Writing Quality and Process

This study investigates the impact of explicit Strategy-based Instruction (SBI) in pre-writing strategies on the writing performance of first-year English as a Foreign Language (EFL) students. Moving beyond the traditional Product-Oriented Approach, which primarily focuses on the final written text, the research adopts the Process Approach to Writing, emphasizing the stages of idea generation, organization, drafting, and revision. The instructional framework was grounded in the Cognitive Academic Language Learning Approach (CALLA) model (Chamot et al., 1991), which integrates content and language learning through the explicit teaching of cognitive and metacognitive strategies. A quantitative experimental design is employed to examine the potential influence of explicit instruction in planning, monitoring, and evaluating the writing process on students’ writing quality. Over nine weeks, the experimental group participated in structured workshops covering brainstorming, outlining, mind mapping, goal setting, and self-questioning techniques, while the control group followed standard writing instruction. Data were collected from pre- and post-intervention writing tasks, evaluated with an analytic scoring rubric assessing content, organization, vocabulary, language use, and mechanics. Statistical analysis revealed a significant improvement in the quality of writing achieved by the experimental group, particularly in the organization of ideas and clarity of expression, compared to the control group. The findings suggest that the integration of pre-writing strategy instruction not only enhances the written product but also fosters greater learner autonomy and awareness of the writing process. The study concludes that embedding explicit pre-writing strategy instruction within the EFL writing curriculum provides a valuable means to strengthen students’ writing proficiency. Such instruction equips learners with transferable skills that improve performance across academic tasks, supporting both language development and academic success.
