This paper introduces a case study on the development of the evaluation system for capstone design course which is usually provided at engineering education program. A capstone design is an engineering education course which aims to improve the students' ability on analysis and design of practical industrial problems by use of overall engineering knowledge which has been learned in undergraduate program. Firstly, this paper provides a literature review on evaluation indices and methods related with a capstone design course. Secondly, the evaluation system for learning outcomes of capstone design course is described. The evaluation system for learning outcomes of capstone design course provided in this paper could be referred by other universities opening a capstone design course, and used to design an evaluation system for internship program or education course which is provided as an industry-academic connection program.

In non-engineering departments such as cosmetology as well, capstone design has been operated as an educational program and evaluation method, generating some positive educational effects. To examine the adoption of capstone design among domestic cosmetology-related college curriculums, this study investigated the total number of credits granted, distribution of academic departments by school, supporting units within academic departments and schools and receipt of government subsidy from the Ministry of Education, and the results found the followings: In 2018, a total of 3,590 students from 31 departments under school of natural sciences and 22 departments under school of art and physical education completed cosmetology-related capstone design courses. In average, each student was assisted by KRW 90,532. The supporting units were operated in cooperation with office of academic affairs (23 colleges), academia-industry cooperation foundation (21 colleges) and strategic support center for government-funded projects (8 colleges). The course titles differed by college. In fact, new and unique capstone design course titles have been used by academic major. It is anticipated that the study results would be available as basic data needed to enhance educational effects for applying capstone design courses and planning government-funded projects, search new items and improve their utilization.

The capstone design course allows students to synthesize solutions to open ended problems. However without some urging, the students tend to focus on the easy part of the project-a single technical solution. The paper deals with some experience in bringing the more demanding aspects of technical projects into the design course. These include: (1) defining the real project with your customer will we know when we're done?. (2) Planning for success. Resource analysis-time, money knowledge, equipment and all of their interactions. (3) What is the best solution? Holding design reviews and comparing alternatives. (4) Communication skills. How do you keep the design team, the boss, and the customer up to date? (5) Presentation of project information in written and verbal forms. (6) Team dynamics. How to support the development of high performance teams? (7) Social skills. Why do I have to deal differently with Mary than with Anne to get their commitment and support? (8) Conflict. Why you need it and how to manage it. Each of the above topics could be a course in itself, but the capstone design course is an ideal place to discuss and exhibit the interaction of these complex issues. These discussions sow the seeds that will allow our graduates to perform at a higher level in all of their future project activities.

Assessment in capstone engineering design courses is vital to engineering education programs. The capstone design course is the climax of design education and often the context for much of the assessment done in engineering degree programs. Capstone design course instructors’ admittedly low confidence for assessing student performance in these courses poses a crucial obstacle to the assessment process. A key issue is a lack of clear outcomes definition for engineering design and sound, defensible assessments for these outcomes. This paper draws from findings in design literature and from engineering design education experience to construct a conceptual model of engineering design that guides development of associated design learning outcomes and assessment of student achievements in design. A conceptual model of design is vital to design education, because it is one of three essential cornerstones— model, observation, and interpretation— for constructing assessments. In the context of an engineering classroom, design performance produces two different and complementary types of outcomes: learner development and solution development. Further, design is: open-ended, iterative, creative, collaborative, goal-driven, process-intensive, productfocused, customer-oriented, value-added, and constrained by society. Learner and solution development usually progresses from a state of students’ fragmented understanding and ideas to a more mature state of integrated understanding and design solutions. The proposed conceptual model for engineering design identifies four areas of performance that describe design: (1) personal capacity, (2) team processes, (3) solution requirements, and (4) solution assets. The first two characterize learner development and the latter two characterize solution development. Personal capacity is the designer’s development of skills which support technically sound and responsible design. Team processes address a team’s behaviors and productivity in design activities. Solution requirements address the team’s understanding of stakeholder needs and concerns. Solution assets encompass the value added, practicality, and impact of the design solution. These four performance areas are essential to design. They identify performances that develop over time, contribute to the success of design outcomes, and stimulate growth in one another for integrated enhancement of design performance. They also provide the basis for a versatile, comprehensive definition of engineering design performance that can guide instruction and can focus assessments in capstone engineering design courses.

Reports on the viability, success, and future of Capstone design courses.

One of the more difficult tasks in engineering education is to effectively teach the concept of “design.” The design process is very broad and involves a wide range of activities, from abstract thinking to detailed modeling and calculations. In Engineering Design, author Rudolph J. Eggert presents a well-structured and thorough overview of engineering design concepts and methods. A major strength of this book is the presentation of the overall design process, the illustration of the systematic concepts that are involved in every phase of design, and definitions of the terms that are used in design. The author has experience with various organizations, including General Electric, Fisher-Price Toys, Wurlitzer, and the New York State Energy and Development Authority, and that experience with the design process no doubt contributed to the effective organization of this text. The author states that this is a text for undergraduate or firstyear graduate engineering students. He also states that the book has a focus of integrating engineering design with topics about the business of manufacturing. This reviewer teaches civil engineering. In my opinion this textbook might be particularly appropriate for use in senior-level capstone design courses. It is my observation that engineering educators are very good at teaching the science of design. By this I mean they are good at making appropriate engineering calculations once a design concept has been established. However, the more abstract processes of design, such as developing an initial design concept or working with customers, are not as easy to teach. The strength of this textbook is its presentation of a coherent structure for understanding the more abstract processes. In this book Rudolph Eggert provides a systematic description for every phase of the design process. Chapter 3 gives an example of the design of a motorcycle that clearly illustrates the steps involved in developing design concepts. Other examples in the text also use items that students can relate to, including the design of a coffee pot and the manufacturing of bicycles. The discussion of customer satisfaction curves, in Chapters 3 and 8, is particularly useful in terms of providing the basis for the concepts of performance functions and ultimately multicriteria decision analysis techniques. These tools provide a basis for both guiding decisions as well as documenting decisions made during the design process. Chapter 10 covers topics of design failure, safety, and environment that it is crucial to present to engineering students. Finally, Chapter 14 on Projects, Teamwork, and Ethics has some very useful material. While I believe that this would be a textbook strongly worth considering for an engineering capstone design course, as a civil engineer I would have liked some detailed examples of design that relate to large, one-of-a-kind projects. While the material

BACKGROUND Capstone design courses seek to prepare engineering students for industry by challenging student teams to solve real-world problems. To improve this preparation, university programs have recently focused on creating multidisciplinary teams. However, there is limited quantitative evidence showing that multidisciplinary student engineering teams develop higher quality projects or are better prepared for the work force.

The purpose of this study is to examine how industry sponsors influence student engagement in mechanical engineering capstone design courses. While sponsor partnerships are intended to enhance the authenticity of capstone experiences, their involvement can shape how students participate in and value design activities. Using a constructivist grounded theory approach, we analyzed semi-structured interviews with nine students from two industry-sponsored capstone teams selected for their contrasting sponsor interactions. Findings indicate that sponsors affect engagement through structural mechanisms (namely, role assignment, role enactment, and influence over design processes), and relational mechanisms (communication practices and investment in student success). High-autonomy role selection, flexible role boundaries, and opportunities for design agency-supported engagement, ownership, and alignment with professional practice. In contrast, sponsor-imposed roles, rigid task boundaries, limited decision-making authority, and low responsiveness often led to frustration, reduced ownership, and disengagement. We conclude that sponsor preparation is critical for supporting student engagement in capstone design. Providing sponsors with clear guidelines to promote student agency, facilitate collaboration, and maintain meaningful communication can help ensure that industry partnerships serve both the educational and professional goals of capstone.

The multitude of specializations within biosystems engineering makes traditional capstone design courses, which typically focus on a single topic, less relevant. In our department, our yearlong capstone design experience involves machine component design. While this experience is useful to students in all concentrations, ideally, students concentrating on biological-, food-, and soil and water-engineering will have a capstone design experience that integrates their unique technical capabilities. New capstone courses should also enhance the broader skills of undergraduate engineers, including teamwork, time and resource management, oral and written communication, and integrated computer skills. However, a variety of issues militate against simply adding new courses to the curriculum, whereas altering existing courses to provide new content is more acceptable. We report here on two years (four semesters) of experience with a hybrid design course based on two existing design courses, and appropriate to biological-, soil and water-, and food-engineering students. The catalyst for this hybrid course was an invitation to enter the Padnos Design Competition, which our students won with their first year’s effort, despite lukewarm course evaluations. In this paper we discuss this paradox, describe changes we have suggested for our entire curricula based on our experiences in the design sequence, and explain how we are modifying our presentation of technical material to better suit the needs of the design course.

Using Mini-Projects to Foster Student Collaboration in Multi-Disciplinary Capstone Design CourseWith a strong emphasis in multi-disciplinary teaming and projects by accreditation organizationssuch as ABET, and the need from industry to hire students with such a background, the twosemester capstone design sequence at the author’s department has combined students from fourdegree programs: computer engineering, electrical engineering, and software engineering. Thiscourse is co-instructed by three faculty: one software engineering, one computer engineering,and one electrical engineering. While this approach provides the students with the desiredexperience in working in multi-disciplinary teams, it also comes with its share of challenges forboth faculty and students.For the students, the challenges include a lack of familiarity of concepts, terminologies, tools,and methodologies across disciplines. For example, students in electrical engineering may havevery little exposure to some of the engineering processes more common with software andsystems engineering. Similarly, software engineers have little exposure with electricalengineering concepts or working with physical hardware. A second major challenge is thatstudents are unaware of the expectations and structure of the capstone project environment.For the faculty, each academic year introduces a new cohort of students. It is difficult for facultymembers to know the strengths, weaknesses, interpersonal issues, etc. of all of the students in theclass. This makes it difficult to assign the students to teams because they are unaware of eachstudent’s level of knowledge, work ethic, and leadership.To address these challenges, the authors have introduced the notion of mini-projects to theircapstone design course sequence. A mini-project is a small project that is designed for a smallgroup of students (4 to 5) working on a task for about two weeks. Each team is made up ofstudents from all three of the engineering disciplines. The three mini-projects include elementsof computer engineering, software engineering, and electrical engineering, which allows eachstudent to demonstrate their unique skills to the problem at hand. The students are expected tofollow the agile design methodologies, which are utilized throughout the semester. At the end ofthe project, written deliverables and a demonstration are provided by the students.In this paper, the authors highlight their experiences using mini-projects for their capstone designcourse. Each of the mini-projects will be presented in detail. The authors shall discuss whichelements of the mini-project worked, and which did not. The paper also includes studentfeedback regarding the process derived from student surveys and their peer evaluations. Finally,suggestions are made regarding how these projects would be used for future academic years.

A critical open question in the mechanical engineering pedagogical literature is whether Capstone senior design can be taught as effectively online as in-person with emphasis on whether group work conducted under these contrasting conditions is equally effective. The onset of COVID-19 induced a natural experiment enabling comparison of engineering student group work conducted in-person versus all-online. Group work is an essential element of mechanical engineering education codified by Student Outcome 5 of ABET Criterion 3 (Groupwork). Peer evaluation is a common engineering group work assessment, especially in Capstone design courses. In this paper, recurring peer evaluations are evaluated to quantify how well students performed in groups within a longitudinal study conducted across five semesters of a mechanical engineering Capstone senior design course. In UF’s Mechanical Engineering Capstone courses, recuring peer evaluation surveys tied to group assignment deadlines were already established prior to COVID-19. By continuing to deploy this same survey when courses transitioned online during the pandemic, three full semesters of group performance data were collected when students were forced to meet remotely. As students returned to campus, the same survey provided comparative data for two semesters when students were meeting in person. These collected data represent a quantitative tool to evaluate how online vs. in-person group meeting setting impacts the quality of teamwork. This work shows that online vs. in-person meeting environments DID NOT have statistically significant impacts on teamwork performance for mechanical engineering Capstone students in the semesters being evaluated. This result suggests that ABET Criterion 3 Student Outcome 5 can be met just as effectively in online or in-person Capstone courses. This important result debunks the misconception that the quality and fidelity of Capstone groupwork is somehow diminished when senior design is taught online to learners remote from each other over the Internet. This finding adds to the growing body of evidence supporting the viability of an all-online Bachelor of Science in mechanical engineering program capable of receiving and maintaining ABET accreditation. Moreover, a forward-looking online ME program can include an effective Capstone senior design course with rich student groupwork interactions of quality equal to those experienced by students when meeting in-person.

The impact of cognitive mode diversity on team performance and student satisfaction was assessed qualitatively and quantitatively in a capstone chemical engineering design course. In the capstone design course, students were permitted to form their own teams and the distribution of cognitive modes was assessed. In a concurrent design course, the same group of students performed projects in instructor-formed teams that optimized the distribution of cognitive modes. The results indicated no significant difference in team satisfaction between teams that had different levels of cognitive diversity. Although trends seemed to indicate higher rank in the course and greater independence and creativity for groups with higher cognitive diversity, these differences were not statistically significant. Generally, students seemed to have similar experiences in student-formed and instructor-formed groups. However, qualitative comments seem to indicate that groups may have worked more professionally and cohesively in the more cognitively-diverse, instructor-formed groups.

In a multifaceted course such as senior capstone design, it is integral to ensure students are receiving a value adding experience. In most universities across the United States, senior capstone design is a multiple semester sequence where design is heavily emphasized and students are encouraged to test their skills, both technical and nontechnical, by solving and implementing solutions to real industry problems. Given the nature of design courses, the takeaways are not things that can be measured solely through the use of a letter grade. Rather, an in-depth reflective interview must be performed to fully comprehend what students received from the course. In this study, an In-Depth Interview Protocol was developed to understand the effectiveness of engineering design courses and improve design education as a whole. This paper outlines the phases that contribute towards the development of an effective interview protocol for implementation in senior capstone design curriculum. The formulation and considerations are outlined with respect to design curriculum and student success. This protocol will be utilized to perform a Reflection Interview for each senior design project team at the end of the spring 2019 semester. The assignment is not graded and is inquisitive on the students’ perceptions of motivation during their time at Florida Tech. The qualitative data gathered will be eligible for further studies and analysis.

The purpose of this study was to enhance early childhood teachers’ digital teaching competence within a play-based curriculum by applying a capstone design–based teaching–learning model and examining its implementation process and effects. To this end, a 15-week capstone design course was conducted with 24 in-service teachers enrolled in an advanced early childhood education program at a three-year college in Seoul. Using a mixed-methods design, qualitative data were collected from reflective journals, group discussion records, classroom observations, and final reports, while quantitative data were obtained through pre- and post-tests measuring digital play support competence. Qualitative findings indicated that teachers reconceptualized digital media as an educational mediator supporting play expansion and teacher–child interaction, and developed practical digital knowledge through reflective problem-solving processes. Quantitative results showed statistically significant improvements across overall digital play support competence and all sub-factors. These findings suggest that the capstone design–based teaching–learning model is an effective approach for helping teachers explore the educational value of digital media and internalize practical competence within a play-based curriculum. This study is significant in presenting a field-based capstone design teaching–learning model for implementing digital education in early childhood teacher education

Senior design projects can be a way to bring the university closer to societal needs. This paper describes how the senior capstone design courses in power engineering developed at the University of Puerto Rico-Mayagiiez (UPRM) strive to provide a service to society. These projects deal with societal needs, and are part of design courses that culminate the major design experience as specified by ABET. Teams of students identify a society-based problem, propose a design solution, perform measurements/simulations and present the final analysis and design to an industry or community partner. An important aspect of the projects is the inclusion of both technical and social constraints such as safety and environmental issues. These design experiences are an ideal way to understanding the new challenges in power systems planning, policy, analysis and design
