This document discusses a study that used blogs to involve students in self and peer assessment of oral presentations. The study aimed to develop students' autonomy, communication skills, and key competences. Students gave feedback on presentations through a class blog. The feedback was analyzed to see if it reflected the assessment criteria and how politeness strategies were used. Most positive feedback addressed presentation structure and materials, while negative feedback focused more on external factors. Students generally used positive politeness strategies when providing feedback, though some used direct negative comments. The experience helped meet learning objectives but had some technical and timing issues. Blogs show potential for developing students' skills if integrated throughout a course.
