Base Knowledge
Teaching Methodologies
– Expository methodology for the presentation of theoretical concepts
– Monitoring of practical cases that illustrate the subjects presented and allow the perception by the students of the application of the concepts enunciated
– Analysis of articles, viewing of videos and case studies
– Contact with ESAC’s farm and others nearby.
