The goal of most of theselaboratory courses is to give the students hands-on experience working with hardware andimplementing control algorithms while learning the theory in an accompanying lecture course.As early as 1981, Balchen et al. [2] asserted that the criteria for a good experiment is that itshould (1) demonstrate important

the simplicity to be built by students over the course offive semesters. The research is designed to test two hypotheses: 1. A long-term design project that integrates knowledge from multiple courses strengthens student knowledge retention. 2. A large-scale design project requiring tools from many courses improves student problem-solving and design skills.By integrating five semesters of the mechanical engineering curriculum into a cohesive whole,this project has the potential to transform the way undergraduate education is delivered. Beforeand after testing is being conducted to assess: a) Change in retention between courses and b)Change in student problem-solving and design skills.The centerpiece of the hybrid powertrain is

Each lab group also does a term long group project in which they design,execute, and report on an experiment of their choosing, using borrowed lab equipment andworking during open lab times.The current labs and the project were developed prior to the current study. The requirementsgiven for each lab and the project were analyzed to determine whether or not the existingassignments explicitly asked for the desired behaviors determined from the literature review. Theresults, listed below in Table 1, show that all of the desired behaviors were requested explicitlyin a minimum of two assignments, with six of the nine behaviors

For example, using MATLAB to operate an Arduino microcontroller requires Simulink,which adds another layer of complexity.

However, thisdocument indicates that for more systemic change across STEM instruction, researchers need todevelop/evaluate pedagogical innovations that do not require substantial external funding ortime, and therefore can be easily adopted by other educators.1 This was one of the motivationsfor undertaking the study presented in this paper.The inquiry-based learning activities described in this paper address the necessity for engaging,student-centered experiences in the freshman civil/structural engineering curriculum with arelatively

For example, studentshave difficulty translating skills learned in math classes to solving problems in physics classes [2].As engineering educators, we are called to assist students’ integration of material across thecurriculum [3] [4]. The ability to transfer knowledge to new situations requires students must workthrough Bloom’s domains to develop these intellectual skills [5].

Linear Circuits had alaboratory component that met bi-weekly, Electronics 1 had a weekly laboratory, and Signalsand Systems had no laboratory at all. The first and third courses were assigned 3 credit hours, thesecond 4 credit hours. In this scenario, the students viewed each course as its own entity andfrequently did not make the connections between the concepts in each. Electronics 1 wouldrequire a massive review of basic circuit concepts, and students did not see how Signals andSystems was anything other than a straight mathematics course, with no relevance to workingwith real devices.All electrical and computer engineering students study

In theprocess, students must identify testable and quantifiable attributes of the product, repeatcontrolled measurements, and build confidence in their outcomes. At the end, the teams mustweigh results to recommend a superior brand. While the project is designed to be student-driven,there are several milestones to guide their progress. These milestones are elaborated below usingan example of ‘superglue’ as a product of choice by a typical student team (See Fig. 1). Theinstructor

While the extruder had a classic PID(Proportional Integral Derivative) temperature controller, the spool motor did not work asintended. It seems that its motor driver would quickly overheat and stop applying power to thespool motor. So, the spool mechanism was bypassed. The extrusion machine was placed near theend of a table and the filament was allowed to simply drop on the floor. This worked, but itrequired some extra effort to wind filament onto the spool. Also, some experimentation with theextrusion machine was required to achieve the optimal extrusion

Some of these exerciseshave a basis in a previous project by Gerald Recktenwald and Robert Edwards (Engineering ofEveryday Things (EET))1 which had a focus on laboratory exercises.
