    Development of a Hybrid Heat and Mass Transfer Course
    (ASME, 2018-11) Mendez, Julie; IUPUC Division of Mechanical Engineering
    This work describes the development of a hybrid junior-level 4-credit-hour heat and mass transfer course. The lecture portion of the course was developed as approximately 80% online. The students and instructor met in person for the lecture portion of the course once every other week for 50 minutes, with the remaining activities completed online. The laboratory portion of the course remained in the traditional face-to-face format. Specifications grading was used to determine final course grades. This paper will describe the course structure, types of assignments, and use of face-to-face class time. Student performance in the hybrid course is compared to previous student performance in the same course taught in a face-to-face format. Student feedback and instructor observations are shared.

    Instructor and Student Experiences with In-Class Polling Options
    (Purdue University, 2019) Mendez, Julie; IUPUC Division of Mechanical Engineering
    Active learning pedagogy has been shown to improve student performance in engineering courses. One active learning technique is Peer Instruction, where students individually answer a poll question, and discuss answer choices with a classmate before answering the same question again. There are various options to conduct in-class polling, from low-tech options, such as holding up fingers or a colored card, to more costly digital technologies, such as commercial platforms that require a dedicated device or a student’s own mobile device. Previous studies have indicated that the pedagogy matters more than the platform or technology used to conduct polling. However, different platforms allow for different affordances not present in some low-tech options. The high-tech options afford some benefits, including being able to ask questions other than multiple choice, such as open response. The purpose of this study is to gain insight into student preferences and to explore benefits and disadvantages of the different platforms from an instructor prospective. Two groups of students were surveyed: one group who completed a course using Plickers, a low-tech system, and another group from two different courses who used the Top Hat Classroom application on their mobile devices. The survey results indicated that the students had a mostly positive experience with each platform. Benefits and drawbacks from an instructor perspective are described.

    Intentional Use of the Learning Management System: A Case Study in Self-Regulatory Behaviors in a Blended Undergraduate Thermodynamics Course
    (ASEE, 2021) Mendez, Julie; IUPUC Division of Mechanical Engineering
    In a blended undergraduate thermodynamics course, affordances within a learning management system (LMS) were used to highlight student learning outcomes, require foundational course content to be completed before attempting more complex topics, provide mastery-oriented feedback, allow students to track their progress, and promote metacognitive reflection. This paper describes the use of these options within the Canvas LMS. Additionally, this study investigated whether student self-regulatory behaviors changed during the course. Students were asked to complete a survey about their metacognitive self-regulatory activities related to studying for this course. The first survey was completed during the fifth week of the course, after most students had completed two reflection assignments. The same survey questions were administered a second time, during the final two weeks of the course. Survey results suggest some increase in student self-regulatory behaviors during the course. These results suggest that, near the end of the course, students were more likely to set study goals for themselves.

    Standards-Based Specifications Grading in a Hybrid Course
    (ASEE, 2018-06) Mendez, Julie; IUPUC Division of Mechanical Engineering
    Standards-based grading is being used increasingly in engineering courses in place of a traditional points-based grading system. Benefits of standards-based grading include clearly matching course assessments to the learning objectives and putting more focus on learning instead of grades. In specifications grading, students are given detailed requirements with all assignments, which are graded pass/fail. The course grade is based on the number of assignments successfully completed. As more undergraduate courses are offered in online or hybrid formats, there is little documentation of the use of standards-based grading or specifications grading in these course delivery methods in engineering. This work describes the implementation of standards-based specifications grading (SBSG) in a hybrid (approximately 80% online) undergraduate thermodynamics course.
