  En este estudio utilizamos la generación de ejemplos y la definición deconceptos por estudiantes para indagar en el conocimiento conceptualimplícito y explícito del concepto ecuación que han adquirido en laEducación Secundaria. Los estudiantes mostraron facilidad paragenerar ejemplos de ecuaciones y determinar diferencias entre ellos,dando evidencias de su conocimiento conceptual implícito. En cuanto alexplícito, manifestaron dificultades para definir el concepto ecuación.Generar ejemplos les ayudó a identificar elementos comunes,generalizar y expresar verbalmente, aunque con ciertas limitaciones, loque para ellos es una ecuación. Examples and Definitions of Equations: A Window to the ConceptualKnowledge of Secondary StudentsIn this study, we use the generation of examples and the definition ofconcepts by students to study their implicit and explicit conceptualknowledge of the concept of equation acquired in secondary education.Students showed facility to generate examples of equations and todetermine differences between them, giving evidences of their implicitconceptual knowledge.
