The process control virtual laboratory is created by using LabVIEW for demonstrating process control via manipulating a simulated model of a physical process. In this study, a system of convection heat transfer in a rectangular duct is set up and connected with a data acquisition card and a computer serving for an advanced virtual laboratory aimed at supporting teaching and learning in Instrumentation and Control Engineering courses at Pathumwan Institute of Technology. The use of the virtual laboratory facilitates the ongoing evolution of the teaching method from a traditional didactic lecture and laboratory course to a more student-centered approach. The LabVIEW application is used to conduct several tasks including user interface design, publishing and sharing measured data, instrument control and remote access to a system in the Process Control Laboratory. Using LabVIEW software, students can familiarize the basic skills necessary to use equipment and software because the control systems in many industrial processes can be implemented on a computer which runs on LabVIEW.

Resumo Os laboratórios virtuais utilizados no ensino de Química se constituem importantes recursos didáticos para o avanço dos processos de ensino e aprendizagem, ao passo que podem contribuir para ações de mediação na construção do conhecimento. A presente pesquisa teve como objetivo analisar as representações quantitativas que estão presentes nas interfaces de laboratórios virtuais à luz da Semiótica Peirceana. É uma pesquisa qualitativa exploratória, realizada no repositório portal PhET–Interative Simulation. No percurso da pesquisa foram encontrados 51 aplicativos, desses seis exibiam características de laboratório virtual e três foram semioticamente analisados. Os resultados indicam que três laboratórios apresentam disposições parcialmente satisfatórias nas representações quantitativas que abordam. Esses podem vir a contribuir para o fortalecimento do ensino da Química, por meio de ilustrações, simulações e a participação interativa do estudante. Quanto às possibilidades, esses oferecem diferentes ambientes, formatos e modelos para o estudo desta ciência. Também foram encontradas limitações como a insuficiência de signos iconográficos de ordem quantitativa considerados indispensáveis na conjuntura conceitual de determinados tópicos da Química. As indicações desta pesquisa são para se pensar a respeito dos signos que vão representar a natureza quantitativa da Química, transformando os desafios em possibilidades para os processos de ensino e aprendizagem desta ciência.

Abstract Virtual laboratories used in chemistry teaching are important didactic resources for the advancement of teaching and learning processes, while they can contribute to mediation actions in the knowledge construction. This research aims to analyze the quantitative representations that are present in the virtual laboratories interfaces in light of Peircean semiotics. It is an exploratory qualitative research, conducted at the portal PhET – Interative Simulation. During the research, 51 applications were found, of these, 6 exhibited virtual laboratory characteristics and three were semiotically analyzed. The results indicate that three laboratories have partially satisfactory arrangements in the quantitative representations they address. They can contribute to the strengthening of chemistry teaching through illustrations, simulations and interactive student participation. As for the possibilities they offer different environments, formats and models for the study of this science. Limitations were also found as the insufficiency of quantitative iconographic signs considered indispensable in the conceptual conjuncture of certain topics of chemistry. The indications of this research are to think about the signs that will represent the Chemistry quantitative nature, turning the challenges into possibilities for the teaching and learning processes of this science. Keywords: Semiotics. Chemistry Teaching. Virtual Labs.
