Una de ellas es la virtualización de prácticas que permita una alternativa no presencial en el caso de dificultades para su realización. Hay disponibles muchos programas comerciales que permiten dicha virtualización, pero para un mejor encaje entre las convencionales y las virtuales, se ha procedido a la programación de herramientas de cálculo específicas mediante Visual Basic de Excel. En este trabajo se describe una práctica de ácido-base. Se resume la base teórica, el montaje experimental para la práctica tradicional, y la herramienta de cálculo programada para emular la obtención de datos experimentales. Se incluyen instrucciones de uso y algún detalle de programación. La práctica virtual se ha probado con grupos de unos 70 alumnos y, previa breve explicación, ha funcionado correctamente sin problemas técnicos. Los resultados obtenidos son satisfactorios comparando con el método tradicional, y el análisis de las calificaciones de los alumnos muestra que las competencias adquiridas son comparables en ambas metodologías. Por tanto, se concluye que las practicas virtuales son una opción flexible para la impartición de prácticas en remoto o como complemento a la experimentación tradicional.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The COVID-19 pandemic and the related restrictions forced the reorganization of learning methodology and gave the central role to remote learning even for Laboratory experiments. A possible strategy is virtualizing laboratory practices, which allows a non-face-to-face alternative in the case of difficulties in carrying them out. Although many commercial programs allow such virtualization, specific calculation tools have been programmed to better fit between conventional and virtual. For simplicity, Visual Basic of Excel has been chosen. In this work, an acid-base practice is described. The theoretical basis and the experimental setup used for traditional experimentation are summarized, and the calculation tool programmed to emulate the obtaining experimental data with the instructions for handling is described. The virtual practice has been tested with groups of about 70 students and, with a brief explanation, has worked correctly without technical problems. The results obtained are satisfactory compared to the traditional method since the detailed analysis of the student&#8217;s grades shows that the acquired skills are comparable in both methodologies. Therefore, it can be concluded that virtual practices are a flexible option for teaching remote practices or as a complement to traditional experimentation.]]></p></abstract>
