Design and Implementation of a Chronological Procedure for Solving Engineering Application Problems

Problem-based learning (PBL) is a technique used in the engineering field to enhance meaningful learning acquisition and competencies. This research focuses on the construction and application of a didactic tool consisting of a series of steps (chronological procedure) implemented to solve application exercises in the Engineering field. A quantitative and descriptive investigation was carried out about applying a procedural chronology based on PBL in chemical and biochemical engineering. The chronological proposal consists of data identification, unknown typification, process diagram development, mathematical expression selection and solution, unit analysis, and result attainment. The tool was implemented in a student population enrolled in initial and intermediate courses in chemical and biochemical engineering. A statistical (quantitative) study was conducted to determine the development of thinking and problem-solving skills to determine the technique's efficiency. Statistical results demonstrate that the proposed chronological procedure is a supportive instrument for PBL methodology. The results indicate that the knowledge and application of the chronological procedure contributed to the development and improvement of practical skills in students.
