Students often circumvent the use of steam tables and resort to simpler digital alternatives to retrieve properties. In fact, the steam tables and their digital relatives that supply numeric property values fail to reinforce the fundamentals; namely, how state properties are related to each other. Supplying state properties without context adds to the abstractness of water properties which lack a simple equation of state. Instead, research has demonstrated that replacing the steam tables with property charts can greatly improve student’s ability to visualize property relationships and facilitate the creation of a mental model of the complicated equation of state for water. Recognizing these results, the traditional use of the steam tables for property retrieval was entirely replaced by property charts for an engineering thermodynamics course. To leverage the highly visual nature of the property charts, animated videos and related multimedia resources were produced and used in a flipped classroom setting for instruction. This new implementation greatly reduced instructional load and allowed deeper engagement with the concepts taught. The new instructional practice was evaluated by a controlled impact study and student feedback. The evaluation study showed that the students who used property charts as their primary reference were significantly better at predicting water property trends when compared to students who relied on the steam tables accompanied by property chart sketches. When surveyed, students favored property charts and the supplementary videos for their ability to visually convey the complex relationships. The results support existing research and make a strong case for revising thermodynamics pedagogy within engineering. By embedding an intuitive and evidence-based approach to teach the engineering fundamentals, educators can ensure that students are better equipped for professional practice.  \nKey words: Engineering Curriculum, Visualization, Instructional Design  \nSUMMER 2020 VOLUME 8 ISSUE 2 1  \nADVANCES IN ENGINEERING EDUCATION  \nA Visual Approach to Teaching Properties of Water in Engineering Thermodynamics  \nINTRODUCTION  \nAlmost all engineering thermodynamics textbooks in use today include some form of tabulated properties of water, also known as the steam tables. The steam tables present various thermodynamic properties as a function of pressure P and temperature T across multiple tables of data conventionally divided by phases. Instructors teach how to identify the appropriate tables and use them to retrieve properties; eventually to study the Rankine Cycle. While the Rankine Cycle is an important application within power generation, the table-based retrieval of properties presents a notable hurdle for students and instructors alike (Balmer & Spallholz, 2006; Hagge, et al. , 2017) . Instructors have to dedicate a lecture or more elaborating on the mechanics of property retrieval from the steam tables including a reminder on how to interpolate. Instructors value this exercise either due to engineering tradition or to train students for the Fundamentals of Engineering (FE) exam that continues to rely on a more limited version of the steam tables (Dixon, 2001; Miller, 2007) . Students who struggle with using the steam tables quickly turn to other available resources to solve thermodynamic problems involving water. These alternatives come in the form of a computer application (e. g. , Taylor, et al. , 2008 & EES), web-based tool (e. g. , NIST Webbook, IRC Fluid Property Calculator, & Sm","cbCaicBe87U2xTDY","https://ap.wps.com/l/cbCaicBe87U2xTDY","pdf",2010136,17,"English","# Abstract\n## Introduction\n## Ideal gas law and learning context","[{\"question\":\"Why are steam tables considered challenging for thermodynamics students?\",\"answer\":\"Students often use steam tables in a way that retrieves values without strengthening understanding of how state properties relate.
