. Most of our course outcomes have not changed withchanges in technology. Many of the fundamental concepts remain the same. However, there arechanges that truly reflect fundamental changes:Outcome: Understand decoders and memory expansion techniquesChanges: We do still cover the basics of bus interfacing and memory expansion. However,because we use microcontrollers exclusively and there no longer is an accessible bus system, thisarea has been deemphasized. Approximately, 8 hours of material down to the equivalent of threehours.Outcome: Competency in assembly language programming and programming tools including aprogramming editor, assembler, and debugger.Changes: This outcome has become essential.

Undergraduates in transportation engineering face exceptionallydifficult technical courses comprising sophisticated mathematics, complex physics, and appliedcivil engineering mechanics, which can weaken confidence and self-belief. According to studies,learners who lack confidence in their skills to understand key ideas, use analytical toolseffectively, and apply information to real-world systems are more likely to struggle academicallyor drop out of programs before graduation [1]. As a result, developing instructional approachesthat promote self-efficacy is crucial for transportation engineering student retention andworkforce development.Self-efficacy has been found to

Example from Strength of MaterialsStudents designing a timber ‘T’ beam for a quiz question exemplified how a model and theaccompanying mathematics is, or is not, used in engineering. The beam is constructed using twoplanks by setting one on edge (the stem of the T) and nailing the other down the middle to thetop edge. The quiz question asked students to specify s, the maximum nail spacing required tosafely fasten the two planks together for the given loading. Students learn about internal forcesin statics and then shear flow and shear stress in strength of materials courses. They typicallywork several fastener spacing problems during class and in assigned homework. The quizproblem described a situation where V(x), the internal shear force in the

new approach to STEMinstruction that encompasses the three dimensions of disciplinary core ideas, crosscuttingconcepts, and science and engineering practices. The overarching goals of this approach are to:(1) prepare students in engineering design as a mechanism for developing technological solutionsto everyday problems, and (2) strengthen students’ knowledge of science by their applyingdisciplinary concepts to design solutions [1,2]. The success of these reforms is dependent upondevising ways for teachers to implement the standards with fidelity to strengthen scienceknowledge through authentic engineering tasks [3]. This often requires support, educationalpartnerships, and instructional models to inform pedagogical strategies [4]. The

andresources by the instructor, and difficulty adapting activities from others due to contextual andinstitutional differences are impediments to adopting small-group active learning pedagogies inthe STEM classroom. Yet the students in the STEM classroom remain hungry for hands-onlearning opportunities. It is also worth noting that the authors have informally observed thatcomputer simulation-based exercises are oftentimes not considered “hands-on” by many oftoday’s undergraduate students.This program addresses the aforementioned impediments and student attitudes by assembling adiverse pool of faculty members from a variety of backgrounds (mechanical engineering,electrical engineering, instructional specialists) from universities of every Carnegie

transfer, and validate your model. Thehollow-fiber membrane unit is similar to a shell-and-tube heat exchanger. Basically, blood flowsthrough the inside of the hollow fibers (tubes), and dialysate (clean water) flows through theshell side. Unwanted proteins then diffuse through the fiber walls from the concentrated tubefluid to the dilute shell fluid. It appears that the separation mechanism is analogous to heattransfer in a fluid-fluid shell-and-tube exchanger, but with mass transferring through the wallinstead of heat. However, there is a complication. Since kidneys also remove water from theblood, and since dysfunctional kidneys do not; in the hospital, pressure differences on the tubeand shell sides, enhanced by osmotic pressure differences
