Teaching Methodologies and Assessment Criteria |
The pedagogical methodology foresees expository sessions by the teacher and practical work, is active and cooperative, encouraging reflection and focusing on the student to acquire concepts, problem solving, research and practical work. The teaching/learning activities are part of theoretical and practical classes, using audiovisual means. Carrying out practical work with a laboratory nature. Carrying out a group work, weaving project, presented orally, and discussed in front of the class, encouraging critical analysis of all students. The assessment is based on a written multiple-choice test (50%) and on a project (50%) for the ongoing assessment and the classification of frequency, and an exam. The frequency criterion is 6 values and for approval is 10 values.
