The present study explored the effect of a pedagogical blog on Iranian EFL learners’ creative and critical thinking skills using a mixed-methods approach. In the pedagogical blog, the researchers asked learners divergent and evaluative questions based on Lindley’s model (1993). The quantitative data were collected by administering Creativity Test Questionnaire (ATC) and the Persian version of the California Critical Thinking Skills Test and were analyzed using SPSS Version 16.0 software. The qualitative data consisted of the posts written by the participants of the study in the class blog and were analyzed using thematic analysis. The findings revealed that the pedagogical blog significantly improved the participants’ creative and critical thinking skills, which were represented in their posts by the main themes of fluency, elaboration, and flexibility as components of divergent thinking and inference, evaluation, induction, and reconstruction as features of open and active critical thinking skills. Further findings and implications are discussed in the paper.
