Abstract:

The subject of Ergonomics which is the focus of this work, is taught in the Bachelor's Degree in Industrial Design Engineering and Product Development at the School of Design Engineering of the Polytechnic University of Valencia. The course aims to raise students' awareness of the need to integrate ergonomic aspects from the early stages of the conceptualization process of new products and interfaces, using different design, ergonomics, evaluation and usability techniques. As part of the evaluation of the subject, students are required to complete a multiple choice test where the experience of teaching staff over the years has identified inconsistent understanding of the subject matter or even random answers. To solve this problem, the use of certainty-based marking (CBM) is proposed, an assessment method that allows students to indicate their level of confidence in each answer they provide in a test or questionnaire. This technique makes it possible not only to identify correct or incorrect answers but also to adjust the score based on the degree of certainty indicated by the student. This communication presents the CBM method developed in the Ergonomics course for the certainty-based assessment of students in the field of product design, particularly in the areas of anthropometry and anthropometric design. The initial results provide information about the actual level of knowledge and the level of knowledge perceived by the student. This promotes deeper, more reflective learning and improved academic performance by reducing the number of guessed answers.
