Assessment is "the most powerful weapon teachers have to influence the way students learn and guide their training. One of the main challenges facing teachers at the Universidad de Occidente-Managua is to move from traditional models of assessment, clearly focused on exams and grading, to models of formative assessment, focused on improving learning. Formative assessment seeks to generate systematic processes of self-reflection on one’s own learning, so that students develop greater control over learning to learn. The book reinforces the criterion that formative assessment emphasises qualitative aspects, as it constitutes a permanent analytical observation of the student’s learning process by generating continuous feedback on the effectiveness of what is learned and the way in which it is learned, in order to enable the modification, improvement and enhancement of both from a humanising perspective and not merely as a qualifier.
