This research aims to develop and stimulate argumentative practice in high school chemistry classes based on blogs and looking for answers to the following research question: to what extent did the strategy of using blogs help students develop arguments and what can be said about the structural quality of those arguments? In this perspective, four groups of students received instructions to create blogs on the socio-scientific topic of pesticide use. In all the blogs, arguments were verified that present data, justifications and conclusions, which are essential elements, according to the Toulmin Model. Furthermore, in all the analyzed arguments, there is more than one justification that, in most cases, is accompanied by a backing, indicating their good structural quality.
