such, departments must find creative and effective ways to providing properadvising and mentoring on these topics.One solution, which by itself provides such a high-impact learning experience, is a student-centered / student-led program to aid the department in providing services to students. Ourdepartment developed a student ambassador program to meet these needs. The main objective ofthe student ambassador program is to provide information about the department, major disciplineand university from a student’s perspective.This paper describes the student ambassador and program in more detail, provides preliminaryassessment of its effectiveness through analysis of the ambassador reflection pieces, and offersguidance on developing and

FLS reflections had to be completedbefore class and were meant as a mechanism to ensure students actively watched the videos. Thelast three weeks (thermodynamic cycles) were focused on application and the course project.Pre-recorded videos were not used in this part of the course because the focus is on integratingthe knowledge gained throughout the course and applying that knowledge to solve more complexproblems. The culminating project was a key part of the last three weeks. From start to end,students were given progressively greater ownership and responsibility in applying knowledge.A theoretical framework guiding this

That is, thelearning goals, the materials, the teaching/learning activities, and the feedback and assessment all wereclosely aligned with and supported each other, which was critical to achieve the learning goals andstudent’s success. The course objectives reflected different levels of learning that necessitated differentkinds of assessment. The

Uponfurther reflection, one should realize that even when the refrigerator is unused, as long as it isplugged in, it will consume electricity (i.e., compressor will run) throughout the day and night,and imperfect insulation is, largely, to blame.Others: All other heat source contributions may be lumped into an arbitrary constant without theneed for in-depth analysis. For simplicity, it is assumed zero.Putting everything together, rounding up to the nearest integer, the actual COP is Q c Q food +Q opening+Qinsulation+Qothers 898+10+3623 4531 COP actual

ASME explicitly states the need for engineering andengineering technologists to, “continually learn and sometimes reinvent themselves”9 pg. 13 and“develop new knowledge based on a research effort”9 pg. 32, which is a direct reflection ofcategory 1 and category 5 which describe andragogical learners as increasingly self-directed andself-motivated respectively. These categories describe the need for learning experiences to beorganized around competency based categories that will allow learners to live more effectively inthe future and acknowledging that knowledge gained through experiences are more meaningfulthan that which is abstracted from professional practice.

The result equates to 371.21Hz, so the natural frequency happens at 371.21Hz. Incomparison, the FFT value of 360 Hz reflects 3% difference. Likely this difference is due tomodel simplifications for the bell which does not fully reflect complete geometry, noise in datacollection, etc. Figure 8: Solidworks

students’ learning level can become higher in Bloom’s Taxonomy. We emphasizedsurveying the students before and after the demonstrations with discussions to get students moreactively involved in the demonstrations. Thus the demonstrations combined with surveysencouraged them to reflect on the concepts they were learning. Our survey questions weredeveloped to improve conceptual thinking and qualitative judgment aspects of the topics versuscalculation of values.Instructors need to understand that students have different learning styles to facilitate theirlearning [17]. For example, some students prefer explanations of theory before exposed topractice and others respond well when practice is connected to theory. Thus, it is important forinstructors to

The second activity, team development, required approximately five minutesand consisted of two questions for team discussion. The first question was an icebreaker,designed to be easy to answer and help the teams engage in conversation. The second questionwas designed to focus on team function and cause reflection on attributes of a team. A sample ofquestions used for each question type is provided in Table 1. After approximately four minutesof team discussion, the instructor asked a subset of the teams to quickly report to the class arepresentative answer to each question, and occasionally followed up with a brief discussion onthe

students haveperformed assignments in which each aspect individually presented the same level of challenge.Table 2 also details other aspects of experimental complexity that increased the challenge level ofthe experiments. One aspect of scaffolding was initial use of a DAQ system to record a singlesignal of data and later using the same system with modifications to record multiple signals ofdata. Another aspect of scaffolding was that measurements in early experiments could be recordedwithout an overall plan for the order in which they should occur. Experiment 3 introduced therequirement that the order in which data was collected must be decided in advance as data collectedout of order would not reflect the desired impact of hysteresis.

While students are eager to apply their technical skills in a design environment,proficiency with professional skills can represent the greatest barrier to success. While freshman andsophomores are exposed to these skills, they must be applied and reflected upon in a

. Student were asked to reflect on how intellectually stimulating the MatLab projects were,with a rating of 1 being “not very stimulating”, a rating of 3 being “just right” and 5 being “toomuch”. The overall results were mediocre, with an average score of 3.10 ± 0.71. We believe thisis because students equate intellectual stimulation with difficulty. Intellectual stimulation isdefined as being encouraged to innovate and be creative, as well as encouraged to critical thinkand problem-solve. Intellectual stimulation involves arousing students’ thoughts and imagination[8]. However students tend to think that more thought means more work and thus an increasedlevel of difficulty. When comparing the results of asking students about the difficulty level

As a result, the instruction, homeworks, and assessments were designed to usethe steam tables as the primary source of water thermodynamic properties. Adopting propertydiagrams as the primary source of water properties meant revising the instruction, homeworksolutions, and the assessment to reflect the change.ImplementationInstruction using Steam TablesThermodynamic properties of mixed phase substances typically follow a complete treatment ofideal gas behavior.

Terms such as “activelearning”, “flipped classrooms”, “hybrid courses”, “reflective thinking”, “standards-based grading”,and others run through the literature (for examples see Felder et. al, 2011[1]).

The technique of adaptivequestioning is effective at addressing common persistent misunderstandings. Examples of thesequence of questions are described. Student feedback shows the use of frequent and persistentquestions which focus on fundamental concepts are effective at improving student mastery offundamental concepts.IntroductionMany engineering students have difficulty explaining the fundamental concepts used in solvingengineering problems. They succeed at algorithmic problem solving but have difficulty explainingthe physical systems being described. This is reflected in low scores on concept inventoryexams
