Experiencia de Diseño y Uso de una Rúbrica para Evaluar Informes de Laboratorio en Formato Publicación Científica

Abstract

In this work, an intervention was designed to contribute to the training of scientists, through redesigning the assessment of an authentic performance task. An analytic rubric to assess a laboratory report written as a scientific paper for a biochemistry course was created and validated. The agreement between referees was 70%. The analysis allowed improving the instrument and identifying weaknesses in the students' performance. Students' perception of this experience was obtained, who declared that they used the rubric, agreeing in regard of its quality, objectivity and pertinence. However, there was no agreement with respect of its usefulness for guiding and providing feedback. Also, no effect was found on the course grades, showing that it is necessary to strengthen the design. As a result, a proposal was generated including: involving students in the definition of the quality standards, guiding the data analysis, including peer assessment and feedback. This experience illustrates the need of continuously updating and improving the teaching practices in order to achieve the learning outcomes.
