A novel approach to exposing students to electronic data acquisition, LabVIEW programming, and experimental design is described herein. This is achieved through the measurement of the Joule–Thomson coefficient of nitrogen and carbon dioxide using a student-built apparatus with slight and convenient adjustments to a classic literature apparatus. A detailed pedagogical approach in the instruction of LabVIEW is described, which may be performed at home, in a computer laboratory, or the physical chemistry laboratory depending on the availability of resources. Additionally, a range of levels of inquiry are described for the instructional mode. Finally, using the methodology described past student groups have been able to determine the Joule-Thomson coefficient of carbon dioxide to be 1.023 ± 0.134 K bar–1, respectively, which is in excellent agreement with the literature  aInorganic carbon compounds  aUpper-Division Undergraduate  aLaboratory Computing  aPhysical Properties  a   uhttps://pubs.acs.org/doi/10.1021/acs.jchemed.3c00849?articleRef=control  cPER  c46038d46037
