students “work as an engineer,” the courseinstructors took a backward design approach to redesign this course. First, learning outcomesfor the course were redefined to highlight problem-solving skills, which are essentialoutcomes according to the ABET criteria. Second, a comprehensive assessment plan wascreated to measure student progress in each of the learning outcomes. Rubrics-based gradingfocuses on assessing five dimensions of student work: the solution’s efficacy, quality oftechnical writing, oral communication, completion of prototypes, and testing plans and results.Finally, the newly developed learning outcomes and assessment plan were aligned withlearning activities in the course, including design, prototyping, testing, as well as

The plan is continuing this 6type of learning procedure [11] and to integrate academic undergraduate or graduate studentgroups to force them solving problems under appropriate guidance but also involving them incollaborative multicultural environment to achieve a simple goal.

to implement and analyze data using the statistical method Design of Experiments (DOE) to aChemE UO laboratory module on Heat Exchangers.Methods A lot of a chemical engineer’s work involves experimentation. DOE is a great tool that can helpwith the basics of planning efficient and effective experiments and then gives a methodology for analyzingthe data obtained by such experiments. In DOE the experimenter changes controllable variables of thesystem or process and then analyzes output data to make inferences about which variables are significantand responsible for the changes observed, as shown in Figure 1 [2]. For that reason, DOE is a powerful toolwhen studying complex systems, such as heat exchangers. Figure 1: Generic

test sensing and measurement instrumentation circuits that use resistors,capacitors, op-amps, and sensors.Specifically, by the end of the course, the student will be able to:● Use a voltage divider to create a sensing circuit;● Produce a Bode plot and explain the frequency response of a circuit;● Design low-pass, high-pass, and band-pass filters/amplifiers;● Analyze data and transform measured data;● Troubleshoot a circuit.The equipment needed to conduct that labs and some of the p-sets include a computer, an AnalogDiscovery 2 (Digilent, https://store.digilentinc.com/), and 5V power supply circuit board,powered by a USB port of students’ laptop computers.

Education through the Experience-based learning.AbstractPrevious studies show that ~50% of engineering students withdraw or change to other majorsmainly due to the poor teaching and advising; the difficulty of the engineering curriculum; andmore importantly - the lack of “belonging” within engineering. Few studies link this problem tonon-engineering courses since most of their first-year courses are demanding and focusing ontopics other than engineering, such as chemistry, mathematics, and physics. To tackle suchissues, the College of Engineering, Architecture, and Technology (CEAT) at Oklahoma StateUniversity (OSU) is in the process of a multiyear plan to transform undergraduate education. TheENDEAVOR is the centerpiece of a

control logic, andthe program adjusts the duty cycle to hold the output voltage constant in the face of varying loadconditions or input voltage changes. The basic front panel in Figure 7 is shown operating infeedback mode, where the duty cycle is adjusting automatically to force the output voltage tomatch the target value. Note that a planned enhancement to this program also provides the userwith the ability to vary feedback gain and modality to study the effects of stability and settlingtime. Again, by implementing all of the control algorithms in software, these changes areexpedited compared to a hardware-only implementation.

. Level 1 entry modules introduce the students to the basics ofprototyping boards, their usages, coding, and understanding. Multiple sensors are introduced atthis level with full descriptions of the circuits, the voltage, amperage, and power requirements.Time is spent educating the students on deciphering the sensor datasheets. Level 2 modules(modules 4-5) involve less detailed instruction sets with references to Level 1 circuit diagrams,constraints and procedures. In level 2 modules students need to plan an experiment anddetermine the necessary procedure to complete the experiment and attain the learning objectivesof the module. The level 3 module (module 6) required the student to read technical specificationsheets for the sensors and actuators

To reinforce the main point, by adding a social aspect, be it withclassmates or with the world, users will have a greater feeling of connection with their work andmight retain more information.Another study performed by Z. Nedic (2013) at the University of South Australia shines light onthe collaborative aspect of remote labs. The study saw international students organizethemselves autonomously to complete group lab assignments and recorded their planning andcommunication. The results showed that students, despite being from different countries,exhibited politeness when trying to create social groups and complete the remote labs. The studygives hope to the notion of creating a more connected educational system where students

determining and teaching bestpractice make at least three important contributions to science and engineering education. First,they offer students a contextualized experience for cumulative knowledge-building and then anopportunity to present that knowledge in ways consistent with a vertical knowledge structure thatthe community of scientists and engineers both understands and values. Second, too often labnotebooks are trivialized as simple recounts. That may provide some explanation for the lack ofguidance. But, as we see in Jaun’s entry, notebooks can serve several purposes, e.g., planning,problem-solving, realizing the best possible solution (rather than the ‘right’ solution typical ofhomework problem sets) – actual knowledge practices critical to
