using rubrics to assess: (1)problem definition in a global context, (2) life cycle assessment skills, (3) life cycle cost analysisskills, (4) ability to integrate social and cultural implications of proposed solutions, (5) writtencommunication, and (6) oral communication. Students performed well in defining problems in aglobal context, conducting an economic analysis, and communicating via oral presentations.Improvements could be made in assessing environmental impacts, accounting for socialimplications of proposed solutions, and written communication via written reports. The self-efficacy questionnaire highlighted that increased communication between students andstakeholders in Costa Rica could improve understandings of social and cultural

An unconventionalsolution, such as co-locating engineering and humanities programs in the same department, canaddress these needs by helping to provide environmental engineers both breadth and depth(Figure 1).Figure 1.

have recently been organized into the five grandchallenges released by the National Academy of Engineering (NAE) and National Academy ofSciences (NAS) in “Environmental Engineering for the 21st Century: Addressing GrandChallenges” [1]. The five grand challenges are (1) sustainably supply food, water, and energy;(2) curb climate change and adapt to its impacts; (3) design a future without pollution and waste;(4) create efficient, healthy, resilient cities; and (5) foster informed decisions and actions [1].These grand challenges align with the issues presented and discussed in the Engineer of 2020 [2]and the United Nations’ Sustainable Development Goals (SDGs) [3].

Improving students’ conceptual understanding of arch construction and behavior using physical models of masonry arches in a classroom exerciseIntroductionThe best works of structural engineering strive to find balance among efficiency (the best use ofnatural resources), economy (the best use of public funds), and elegance (a measure of aestheticquality or cultural significance) – all under the umbrella of safety and serviceability [1]. DavidBillington, a long-time Professor at Princeton University, bestowed an honorarium on structuresthat demonstrated this balance, structures that embodied what he called the three ideals ofStructural Art: Scientific, Social, and Symbolic [1].

Field trips to construction sites for design classes candirectly relate class assignments to real structures, giving students a perspective on theinteraction between disciplines (owner, architect, construction managers, sub-contractors andengineers), and boosting confidence of engineering students. However, to maximize theirpotential, tours should be implemented with purpose and relate directly to class material

The disciplines with the most obvious focus onenvironmental issues are environmental studies (EnvS), environmental science (EnvSci), andenvironmental engineering (EnvE). An online search of programs in the U.S. that awardBachelor’s degrees in these areas identified 183 EnvS, 500 EnvSci, and 70 EnvE degrees [1].The number of Bachelor’s degrees awarded in 2014-2015 in these majors were: 6015 EnvS,5723 EnvSci, and 1414 EnvE [2].

The focus of the evaluation lies on a comparison of theparticipants' assessments of their skills and abilities before and after their participation in theEWB Challenge. This work in progress paper explains the structure of this evaluation in detail. 1. IntroductionThe German university teaching system has been in constant change since the Bologna reform(a European-wide process to ensure coherent and comparable education qualifications). It isbecoming increasingly important to intensify the learning process, improve learning outcomesand ultimately improve the quality of teaching (Hochschulforum Digitalisierung 2016).Furthermore, concepts such as the "Third Mission" are on the rise: the idea of
. Professional competencies such as leadership, the ability to designsustainable systems, effective communication, and interdisciplinary teamwork areamong the many skills required by engineers of the future. Functioning effectively as amember of a multidisciplinary team is a requirement for entry into the practice of civilengineering at the professional level. It also states that intradisciplinary andmultidisciplinary teams are needed to solve the complex problems of the future1The recently revised ABET student outcomes (1 through 7) no longer have an explicitoutcome about functioning on multidisciplinary teams; however, it is implicitly stated thatit is still important. Outcome (1) of the new ABET student outcomes state that studentshave “an ability to
students have very little knowledge of infrastructure and havedesigned the course with this in mind. Complex mathematics is not needed in the course as thefocus is to provide students with a holistic view of infrastructure. In addition, real-worldexamples are integrated into the lessons that emphasize the concepts of interconnectivity ofdifferent systems. The course learning outcomes were developed collaboratively by members ofthe CIT-E community of practice in 2015. The process is described by Parker et al. [1]. A courseoutline, specifying 43 lessons that will support the outcomes, was also developed collaborativelyby the community of practice (Table 1). The CIT-E community of practice decided to categorizeinfrastructure into three categories

Prensky noted that contemporaneous students represented a singulargeneration that had grown up with digital technology, which had fundamentally changed howthis generation thought and processed information. The STEM education world took note of Prensky’s observations and began to discuss waysto meet the needs and thought processes of digital natives. In 2004, the National Academy ofEngineering (NAE) published a report entitled “The Engineer of 2020: Visions of Engineering inthe New Century”. In this report, NAE recognizes that we are progressing in age ofextraordinary technological growth and sets forward ideal attributes for the next generation ofengineers. The author
College next year will initiate an engineeringgraduate program with an emphasis on renewable energy and sustainability. ABET (Accreditation Board for Engineering and Technology) criteria, in concert with theUniversity mission, require engineering programs to produce “graduates who pursue life-longlearning through continuing education and/or advanced degrees in engineering or related fields.ABET criteria also require that graduates be able “to design a system, component, or process tomeet desired needs within realistic constraints such as economic, environmental, social, political,ethical, health and safety, manufacturability, and sustainability.” (ABET 2014).1 In accordance with ABET, the ASCE Body of Knowledge initiative and

In this way, technical skills building, as well as attitude and perceptions areevaluated. Results indicate that while similar learning was achieved with the games vstraditional lecture, students’ perception was that the games were not worthwhile in replacinglecture. Details on the games and assessment techniques are included, to allow others to easilyadapt this work.IntroductionIt is now generally accepted that active learning methods can help students learn material at adeeper level [1], and that students enjoy game-based learning.

In prior publications, the results of anonymous student feedbackcollected at the end of the semester have been reported, including: quantitative results ofLikert-scale responses to five common questions; and representative comments to open-ended questions. These prior results suggest that at least two responses are predominant,namely: 1) rejection of mastery learning as “unfamiliar”/“unfair”, or “lazy on the part ofthe professor”; or 2) welcoming of mastery learning as “empowering”, or “an opportunityfor self-ownership of learning on the part of the student”. To improve our understandingof the attitudes of students towards mastery learning, a qualitative approach
Place of HomeworkAbstractDo online quizzes with immediate feedback promote better student learning than homeworkassignments for upper level engineering classes? A junior-level Environmental Engineering classwas reworked to use multiple-choice quizzes in a learning management system rather than paperhomework. Similar approaches have shown encouraging improvement in student motivation [1],in providing feedback to students [2] and in exam performance [3]. An objective for using thisapproach in Environmental Engineering was to allow the students to receive immediate feedbackon their skills. For example, in calculating the pH of a composite water sample (with somesimplifying assumptions), there are common mistakes that students make that will lead
modules and even entire courses. This paper describes the creation of an interdisciplinary module on the topic of Water Sustainability in Cities. The module contributes to meeting a need for accessible teaching materials to help advance the knowledge and skills of students addressing complex and dynamic problems with water infrastructure in cities. The module creation also provided insight into the development of interdisciplinary education modules by multiple instructors from different disciplines and different institutions, a possible approach for the future. The paper therefore has two goals: (1) to present the Water Sustainability in Cities course module and make available for others to incorporate into
environment, and they felt more strongly about the need for continuingenvironmental education to promote environmental stewardship.Introduction The need for an environmental ethic became evident in the 20th century due to a numberof high-profile environmental failures, including those documented in Silent Spring [1] andThomas Hardin’s paper on the tragedy of the commons [2]. The establishment of theEnvironmental Protection Agency (EPA) almost immediately following passage of the NationalEnvironmental Policy Act (NEPA) and the inaugural Earth Day of 1970 further increased publicawareness of the relationship between human activity and environmental quality [3]. This linkwas discussed as early as the 16th century by Malthus [4]. At the heart of

Other students responded positively to thecourse content (i.e., “I learned a lot of practical environmental health information that I plan touse in practice”). Future work should: 1) follow-up with students to identify the value of thecourse in their professional practice after graduation; 2) assess changes in student attitudes andbeliefs from before and after the course; and 3) replicate the course at other institutions toevaluate the effectiveness of the course content and delivery approach independent of thepersonality of the instructor and with a variety of student types.IntroductionThe field today known as “environmental engineering” emerged formally with the creation oftwo organizations
spanning a period of four academic semestersbetween 2014 and 2017 were analyzed using two approaches. Projects were analyzed(1) for the degree of integration of non-technical considerations and (2) by term frequencymining and term frequency-inverse document frequency (tf-idf). The integration of socio-economic and cultural considerations into the course project increased in 2016 and 2017,with five of twelve student teams in 2014 and eight of ten student teams in 2016 and 2017integrating non-technical considerations in their analysis. Gender demographics andgraduate standing were not correlated with the degree of integration of non-technicalconsiderations. Term frequency analysis and tf-idf showed that key terms in the “social”and “energy

At the endof the semester, students completed a survey to evaluate the efficacy of the class activities. Toaddress the need to for civil engineering students to make connections between technicalknowledge gained in school and professional practice5, to use information beyond what is foundin the textbook1,2,3,4,5, and to learn environmental engineering in the context of real-worldproblems5,6,7, the following objectives were developed for the class activity: 1. Identify and evaluate sources of information 2. Connect life experiences with course content 3. Identify real world engineering

Survey results indicate that the EHMs enabled students toincrease their perception of their understanding of environmental engineering and its effect onsociety’s environmental challenges.IntroductionAs our world continues to evolve, an increase in the development of technical solutions is criticalfor meeting society’s growing needs. Today, there are many environmental and social problemsfacing our world.

engineering education, students should have aclear understanding that the nature of their job is directly affecting the environment and theirpractices are governed by the code of ethics, which calls on sustainable development. How weteach or train students to develop their engineering skills, becomes an essential tool to nurturesustainability in their future practice, which was recognized as a pressing issue for educators [1]-[3]. Promoting sustainability as part of everyday practice could establish the missing link toenhance environmental attitudes of engineering students [4], [5].Many empirical studies reported that environmental education, either as a semester course or as asummer program, not only improves knowledge and awareness of environmental
