This study aimed at exploring the effects of inquiry-based learning on students’ writing
performance, critical thinking skills, and motivation towards academic writing. A quasiexperimental
design that employed time-series design with single group participants was used. A
total of 21 EFL undergraduate students who took advanced writing skills course were selected
using comprehensive sampling method. Tests, focus group discussion, and student-reflective
journal were used to gather data. The participants were given three argumentative essay writing
pre-tests and other three argumentative essay writing post-tests before and after the intervention,
inquiry-based argumentative essay writing instruction. While the quantitative data were
analysed using one-way repeated measures MANOVA, paired-samples t-test, and descriptive
statistics, the qualitative data were analysed through narration. The findings revealed that using
inquiry-based learning enhanced students’ writing performance, critical thinking skills, and
increased students’ motivation towards writing. This method developed students’ writing
performance in terms of task achievement, coherence and cohesion, lexical resource, and
grammatical range and accuracy. Besides, it enhanced students' interpretation, analysis,
evaluation, inference, explanation, and self-regulation skills which are the core critical thinking
skills. It also increased students’ motivation towards writing which includes self-efficacy, goal
orientation, belief and affect about writing. Therefore, inquiry-based learning is suggested as a
means to improve students’ writing performance, critical thinking skills, and increase students’
motivation towards writing. Thus, this study recommends researchers, teachers, and students to
pay due attention to inquiry-based learning in their academic journey.
