Fifteen groups composed of engineering students and professionals were videotaped while performing a simulated design task. Using interaction analysis, it was found that professional teams were more likely to engage in management activities, outline an overall design philosophy, and not overlook detailed specifications. Professional teams also adhered tentatively to the early design artifacts; early design attempts were viewed as experiments for acquiring more information about the design space. Student teams were much more likely to engage in a generate and test pattern throughout their design process, making incremental improvements to their current artifact. Although the number of groups was small, these patterns were strong and the differences were statistically significant. It is suggested that these differences are useful for guiding how engineers are educated and for understanding whether students should be used as experimental subjects in engineering design research.

Morphological charts are widely recognized tools in engineering design applications and research. However, a literature gap exists in instructing the representation and exploration of morphological charts. In this paper, an experiment is conducted to understand how morphological charts are explored and what impact functional arrangement has on it. The experiment consisted of two problem statements, each with five different functional arrangements: 1) Most to Least Important Function, 2) Least to Most Important Function, 3) Input to Output Function, 4) Output to Input Function, and 5) Random. Sixty-seven junior mechanical engineering students were provided a prepopulated morphological chart and asked to generate integrated design concepts. The generated concepts were analyzed to determine how frequently a given means is selected, how much of the chart is explored, what is the sequence of exploration, and finally the influence of function ordering on them. Experimental results indicate a tendency to focus more on the initial columns of the chart irrespective of functional order. Moreover, the Most-to-Least-Important functional order results in higher chances and uniformity of design space exploration.

Abstract Objective – Due to the individualized nature of consultations and institutional constraints, research consultations can be challenging to assess. At Texas A&M University Libraries, subject librarians use research consultations to teach information literacy to upper-division engineering student teams working on a technical paper project. This paper describes an action research project designed to evaluate which assessment method for consultations with student teams would provide the most actionable data about the instruction and the consultation logistics as well as optimize librarian time. Methods – For three semesters, we simultaneously used up to four consultation assessment methods: one-minute papers, team process interviews, retrospective interviews, and questionnaires. We followed the action research cycle to plan the assessments, implement the assessments, reflect on the data collected and our experiences implementing the assessments, and revise the assessments for the next semester. Each assessment method was distributed to students enrolled in an engineering course at a different point in the technical paper project. The one-minute paper was given immediately after the consultation. The team process interviews occurred after project deliverables. The questionnaire was distributed in-person on the last day of class. Focus groups were planned for after the assignment was completed, but low participation meant that instead of focus groups we conducted retrospective interviews. We used three criteria to compare the assessments: information provided related to the effectiveness of the instruction, information provided about the logistics of the consultation, and suitability as an assessment method in our context. After comparing the results of the assessment methods and reflecting on our experiences implementing the assessments, we modified the consultation and the assessment methods for the next semester. Results – Each assessment method had strengths and weaknesses. The one-minute papers provided the best responses about the effectiveness of the instruction when questions were framed positively, but required the most staff buy-in to distribute. The team process interviews were time intensive, but provided an essential understanding of how students think about and prepare for each progress report. Recruiting for and scheduling the focus groups required more time and effort than the data collected about the instruction and logistics warranted. The questionnaire provided student perspectives about their learning after the assignment had been completed, collected feedback about the logistics of the consultations, was easy to modify each semester, and required minimal librarian time. Conclusion – Utilizing multiple assessment methods at the same time allowed us to determine what would work best in our context. The questionnaire, which allowed us to collect data on the instruction and consultation logistics, was the most suitable assessment method for us. The description of our assessment methods and our findings can assist other libraries with planning and implementing consultation assessment.

After two years of design research, the near-term goal of the Senior Citizens Department, Regional Niagara, was to build innovative homes to address the issues and programs the studies revealed. The long-term objective was to build homes that would start to change the public perception of long-term care facilities. Featuringa “Town Square”, the home comprises five houses of 20 beds, each providing a different level of care. Corridors are a unique design, and each house has its own dining room facilities and activity room. A central Day Care lounge features dining room facilities for family and friends. The Department hopes the overall design will help to break down the stereotype image of long-term care design, an d provide a suitable environment for the mentally and physically frail, as well as ambulatory residents.

Abstract – First-year engineering students at Vancouver Island University in Canada and second-year engineering students at Tra Vinh University in Vietnam have been brought together to work on a cooperative cornerstone design project as a means to introduce intercultural competencies early in the students' academic experience.  Student teams at each institution were partnered, whereby a design proposal developed by a team at one institution was constructed by their partner team at the other institution. Each team provided stakeholder input early in the design stage, and team pairs established a change management structure to respond to challenges occurring during the construction phase of the project. We explore the challenges and successes of the students experience as they navigated the linguistic, cultural, technical, and geographic barriers towards successfully completing this major design project.

The existing gap of mathematics knowledge was identified as the major contributor to the decline in the students’ performance on the Integral Calculus at the university level. This phenomenon has led to university students’ difficulties in identifying the correct integration techniques and developing understanding on applications of the Integral Calculus. This study aims to analyse the effectiveness of e-INTEGRAL MAP in the learning of Integral Calculus among engineering students of advanced Calculus class. A total of 118 diploma engineering students were involved in an experimental design research to study on the usage and effectiveness of e-INTEGRAL MAP. Study was performed on 65 students in control group and 53 students in treatment group, using the pre-test and post-test experimental design methodology where the effectiveness of the maps was measured through their performance scores. Findings indicate that both control and treatment groups showed significant differences in post-test scores during the two months study. The majority of e-INTEGRAL MAP users found the maps very useful, helpful, easy to understand and user-friendly because it was systematically designed. In conclusion, e-INTEGRAL MAP significantly improved the students’ performance and understanding on the topic of Integral Calculus as compared to the conventional text-book learning.

Although morphological charts are widely taught used tools in engineering design, little formal guidance is provided regarding their representation and exploration. Thus, an experiment was conducted to elucidate the influence of functional ordering on the exploration of morphological charts. Two design prompts were used, each with five different functional arrangements: (1) most-to-least important function, (2) least-to-most important function, (3) input-to-output function, (4) output-to-input function, and (5) Random. Sixty-seven junior mechanical engineering students were asked to generate integrated design concepts from prepopulated morphological charts for each design prompt. The concepts were analyzed to determine the frequency with which a given means was selected, how much of the chart was explored, the sequence of exploration, and the influence of function ordering. Results indicated a tendency to focus upon the initial columns of the chart irrespective of functional order. The most-to-least-important functional order resulted in higher chances and a uniformity of design space exploration.

Abstract This research focuses on improving the outcome of idea generation sessions of interdisciplinary student teams working in the early design stages of a product or solution by measuring the effect of incorporating Design Heuristics Cards at different points of ideation sessions that adhere to the brainstorming guidelines. Using the design thinking methodology, an open-ended challenge was given to the participating teams for a Brainstorming exercise divided into a fifteen-minute individual segment followed by a thirty-minute team ideation segment. Three experimental treatments were designed where Design Heuristics Cards were introduced at different points of the ideation exercise: the start of the individual ideation segment, the start of the team ideation segment, or the second half of the team ideation segment. A fourth control treatment did not introduce the cards at any point but used the Brainstorming guidelines throughout. The metrics observed were Fluency, Novelty, Feasibility, and Market Fit of the ideas generated by the students. Eighty-four students participated in the experiment, with 58.3% being from majors in the College of Engineering, 28.6% from majors in the College of Business Administration, 7.1% from majors in the College of Arts and Sciences, and 6.0% from majors in the College of Agriculture. No significant difference was found among the experimental treatments; however the results are not considered final due to the explorative nature of the study. Recommendations are made on future work and possible improvements to the experiment.

Design is associated with the invention,planning and building a product. Engineering design, inparticular, takes considerable effort, skills, andintegration of knowledge; hence, it is difficult to teachfreshmen this subject since they have not possessed ordeveloped the proper skill set yet. The Faculty ofEngineering at the University of Victoria has beenteaching engineering design (in two successive courses)to all first-year engineering students. In addition toattending plenary lectures, student teams are working oncompetitive projects in the laboratory, while participatingin highly integrated communication modules. In thiswork, we discuss the curricula of these design courses,model of delivery and share our experience for the pastthree years.
