problem solving practice during these discussions, rather thanworking problems at board, which leads to a very passive mode of learning. However, a highlevel of quality control has not been implemented. In Fall 2013, the instructor experimented withteam-based learning as formally defined by Michaelsen8-10. About 1/3 of the content wasdelivered team-based learning style, which was concluded to be a sub-optimal approach for thespecific objectives of this course.In Fall 2014, the solid mechanics course was significantly re-designed using a flipped classroomapproach. The cornerstone of the approach was to use class time for student teams to solveproblems at whiteboards with instructor guidance. The objectives of this paper are to evaluatestudent

JunctionTransistors do not. Due to its very low (sub-ohm) RDS resistances, the MOSFET transistor haslow VDS saturation voltages as compared to the VCE saturation voltages of a BJT. Even lowpower MOSFETs have VDSon voltages of 0.1 volts or less when the BJT VCEsat voltages can be inthe 0.5 to 1 volt range and even higher. This allows the MOSFET to have significantly improvedswitching characteristics over the BJT in comparable applications. In addition, most MOSFETshave an output protection diode which allows utility comparable to a BJT in switching inductiveloads such as relays and motors.Along the same lines, the MOSFET retains its amplification characteristics much closer to its

academicsuccess. At the end of each semester, students receive a grade for each course they complete,which is converted to a numerical value (A = 4, B = 3, C = 2, D = 1, F = 0) and multiplied by thenumber of credit hours to give the number of quality points. Quality points are divided by thenumber of credit hours to determine the GPA. Although this method allows courses withdifferent credit hours to be weighted differently, it does not allow for the relative difficulty ofcourses (i.e. lower level courses are treated as equal to upper level courses) and does not Page 26.589.3distinguish between subject areas so math, physics and engineering topics are

Electrical Power & Machine Control CourseAbstract:This paper describes the eight laboratory experiments developed for the Electrical Power andMachines (ECET 231) course in the Department of Computer, Electrical, and InformationTechnology at Indiana University-Purdue University Fort Wayne (IPFW), Indiana. The labs werefirst used during the Spring Semester of 2011 and have been improved every year since then. Abrief description of each of the eight laboratory experiments, their respective objectives and theresults obtained by some of the students are discussed in this paper. Student assessments for thiscourse/lab are also presented. The feedback has been very positive and encouraging.1. IntroductionA course in electrical power / electrical

Of the questions posed, only the responses to questions 1, 4 and 5 indicated activitiesthat students did not consider cheating. The questions were purposefully situationally vaguemeaning that students were not given any details to enrich their interpretation of the questions.

useful for many engineering programs that use project-based learning and require some form of final written document from students as a metric forgrading.IntroductionABET Criterion 5 requires that “Students must be prepared for engineering practice through acurriculum culminating in a major design experience based on the knowledge and skills acquiredin earlier course work and incorporating appropriate engineering standards and multiple realisticconstraints” 1. Criterion 3 requires that graduates also demonstrate “an ability to communicateeffectively”. Senior Capstone programs address both these criteria within the undergraduatecurriculum. Most capstone programs require the teams to submit a final report and in some casesa proposal as part of the

, In-Class Learning Environment as a Teaching AssistantIntroductionActive learning techniques, when properly implemented, have been shown to improve learningcompared to traditional lecture. A review of active learning by Prince found broad support foractive, collaborative, cooperative, and problem-based learning.1 Specifically, a meta-analysisrevealed that small-group work, one form of active learning, promotes enhanced academicachievement, more favorable attitudes toward learning, and increased persistence in STEMfields.2 Despite the strong evidence, many college engineering courses uphold the status-quo,lecture-only format because changing the structure of a course takes considerable time, planning,and foresight

Hence, in this work we built several PSLEs forsubsequent semesters to further engage and support students in learning how to solve problemsby practicing solving problems5.MethodologyPSLEs were developed by following the design activities proposed by Jonassen2: 1) first weinteracted with the instructors of the studied courses to identify and articulate problems relevantto the discipline; 2) working with corresponding instructor, we analyzed problems, first bycreating a causal model of the problem space; then we conducted an activity theory analysis

Any student whosegap years totaled 5 or more, was classified as a returner. We chose 5 years in order to capture theexperiences of those students who have been out of academia long enough to establish a careerand develop significant experience within a field, as opposed to those students entering theworkforce for 1 or 2 years with the intent to return to school after a short break. We separated outthe responses for returners and traditional students, and for this paper, we focus only on thereturner group with the goal of understanding

is critical to get students engaged in active learningthrough activities such as solving problems, working with each other, asking questions andgetting feedback.To enhance student learning in Statics, researchers at various institutions have explored othermethods for teaching Statics, such as developing concept map and quantifying students’conceptual understanding[1, 2], developing on-line homework or learning modules[3, 4], peer-led-team-learning[5], project-based learning[6], emporium-based course delivery[7].

Engineering Practice course. A small team of two students worked on the design anddevelopment a robotic work-cell that performs a simple sorting operation for quality control,by utilizing multiple pieces of peripheral equipment. The work-cell was intended to be usedas a part of the curriculum for future sections of the ENGR 4700 as a vision systemslaboratory and an introduction to work-cell design. Further use in ENGR 4950 was alsoplanned to incorporate additional features.The overall goal of the project was to create a small work-cell, as illustrated in Figure 1,including a bowl feeder part loading system, a Fanuc M10iA robot, and a Sony XC-56camera to complete a simple part sorting task.

However, according to Richard Mayer, a leading researcher in the area ofeducational psychology, and in particular multimedia learning, we know more about verballearning (words) than we do about visual learning (pictures). We also know more about whatmakes a good live lecture than what makes a good video lecture.1 Mayer defines the multimediaprinciple as the idea that “people learn more deeply from words and pictures than from wordsalone.”2
