Rubistar Introduction The following rubric has been made in the rubistar platform to evaluate oral presentations about experiences in institutions which use constructivism. The rubric contains seven aspects to grade in a scale from one to 4, the items to evaluate are: Tone, Volume, Posture and Eye Contact, Vocabulary, Content, Comprehension and Understanding of the topic. Conclusion The platform called rubistar is one of a kind, it can really help you to develope a useful rubric wich is trustworthy to evaluate. My main issue when making ribrics was to find the right elements to consider and instead of create every aspect and grade it ribistar helped me assigning real measures considering the kind of activity and the skill that is supposed to be evaluated.
