process that is used extensively to removecontaminants from water and air. Environmental engineering faculty typically teach this topic bydescribing mathematical models that are used to quantify adsorption. This approach, by itself,may result in students having an incomplete understanding of adsorption because studentsfrequently have difficulty visualizing scientific phenomena such as the mass transfer process thatoccurs during adsorption. A hands-on laboratory experiment (cf. Speitel, 2001) where studentscollect and analyze adsorption data, may enhance students’ understanding of adsorption.Undeniably, hands-on experiences help students develop a deeper understanding of principlesstudied in and out of the classroom (Butkus et al., 2004; Pfluger

design. The University Curriculum Committee approved the request to change thecontact hours for Structural Analysis from 3 hours of lecture per week to 2 hours of lecture plus2 hours of laboratory per week to accommodate the experiential aspects of these proposedchanges. After assessing the changes to the Structural Analysis course, we will decide whether tomake similar changes in the class meeting times for the Structural Design courses.The Structural Analysis course syllabus lists the following broad goals for the course: a) Students will develop technical skills in classical methods for analysis of determinate and indeterminate structures. b) Students will gain proficiency in analysis structures comprised of trusses, beams, frames

As the tap stand locationremains lower than the location of the reservoir, students can notice water continuing to flow asthe third student is responsible for turning the tap stand valve on and off. However, as soon asthe location of the tap stand is higher than the location of the reservoir, water flow stops. Thus,students realize that the location of the outflow must be lower than the location of the inflowassuming
sizeof 45 students; typically requiring three sections. Teaching assistants are available in the labs toanswer students questions related to the use of the software; AutoCAD or Civil 3D.[2]Laboratory assignments were assigned as either projects or lab experiences depending on therequired effort expected from students. Labs consisted of drawings to complete where the CADsoftware features were demonstrated and video recorded in the lab session. The students wouldtypically have one week, with three hours of lab time in two 1.5-hour sessions, to complete theirdrawings. The projects would also have a laboratory demonstration (and recording) but theassignments were longer in duration and more laboratory sessions (typically four 1.5-hour labs)were
duringclass and many steel design courses do not require a laboratory component. The following paperwill describe how the author uses trash bags with bolt holes to describe the concepts of yieldingand fracture, while also introducing a little bit of comedy into the classroom. Answers to themost common student questions are also provided.MotivationFor the first two or three times the author taught an introductory steel design course, he noticedthat many students were not able to clearly describe yielding in materials. From previous coursesin mechanics of materials and structural analysis, the students recognized that yielding, alongwith fracture, were both limit states to be checked, but they struggled to differentiate between thetwo failure modes and

Demographic information of participating students in 2019 programHands-on activities in Civil and Architectural Engineering:At the camp, students will learn how math and science relate to the field of engineering. Byseeing first-hand what engineers actually do, campers can better decide on a career or disciplinethey want to pursue. Whether a student is interested in clean energy, cars and motorcycles,explosives, or building bridges or towers, the camp will educate them through hands-onactivities, computer laboratory visits and practical demonstrations. The civil and architecturalengineering program is no exception to this exercise. Both programs offer a tour through
material properties of concrete.The first week of the semester in the reinforced concrete course is used to review both the materialproperties of unreinforced concrete and relevant laboratory tests, including compression, splittension, and flexure. The second week of the course is used to introduce the students to themechanical response of reinforced concrete beams, which includes a discussion of the differenttypes of failure modes and an overview of the internal couple method. During the third week ofthe course, the students learn how to calculate the flexural strength of reinforced concrete beamsthrough application of the internal couple method.

Though most of the included studies related to science activities andmany compared field trips as a substitute instruction for class or laboratory instruction, theauthor concluded that Virtually all results indicated that field work should be used in conjunction with, or supplementary to, other methods of instruction.The recommendations stated by McLoughlin (6) are a good starting point for any field trip.Specifically, the field trip should be planned such that students actively seek out information that makes them
recitation or laboratory periods, somost feedback to students is directed through solution sets, comments on graded homework,brief statements made in class and emails to the entire class. If included, recitation sessions couldfocus on more discussion of differences between student and designer member selections, howvarying member sizes would affect overall structural behavior, and some repetition ofcalculations for additional practice. The field trip could also be mandatory if scheduled duringthis time period. Without these periods the methods of communicating these concepts arethrough explanations on solution sets, brief class comments and email. Solution sets includeexplanations of differences between what students designed and what exists in the
excitement that a student has when they encounter more detailed instruction on similartopics in future courses.The format for Springer 1 is also unique as it is scheduled as two 2-hour laboratories but, inactuality, the length of the laboratory period is variable depending on what is being covered on aparticular day. If the material coverage is predominantly lecture-based, then the time period usedmay be as little as 50 minutes. If most of the material coverage is active project-based learningwith little instruction, then the full 2-hour period is used.The first week of the course covers the civil engineering profession and sub-disciplines, history,and societal context as well as an overview of the project.

Professional skills are particularly reinforced in the engineering coursesthrough laboratory reports, technical papers, presentations, design projects, field trips,interactions with practitioners and USCG officers, community outreach activities, andprofessional membership. Significant mentoring and advising takes place throughout cadets’years at the Academy which is also an important component for intellectual development andservice readiness. The approach of using every opportunity to infuse practical, industrial andUSCG relevance into course content has proven successful in fulfilling CGA’s mission.With increasing

By 1980, when ECPD changed its name to the Accreditation Boardfor Engineering and Technology (subsequently to be changed to ABET, Inc.), engineeringaccreditation had become “more rigid and rule-bound,” while “the accreditation criteria grewfrom a few paragraphs … to thirty-plus pages of fine print containing detailed prescriptions forrequired courses, credit hour distributions, numbers of faculty, and laboratory improvement plans[23].” This growth was largely ad hoc and sporadic; it did not follow a systematic process or aregular cycle.In 1992, the ABET leadership established an Accreditation Process Review Committee, whichheld a
