Determining the Volume-size Pore Space Parameters in the Grinding Wheels
Authors: Krukov S. A. , Baydakova N. V. , Shumyacher V. M. 
Published: August 2018

In forming structural and mechanical properties and performance criteria of a grinding wheel, pores are a key player. They are stochastically distributed in the shard of the wheel, have a random size and shape in the limited volume of the wheel shard, which makes it difficult to determine the volume-size parameters of the pore space in the grinding wheel.Experimental and analytical studies of the wheels on the ceramic bond allowed authors to reveal a porosity and pore size dependence on the size of grain, hardness, and structure of wheels, taking into account the type and the quality index of abrasives and also the method of tool modification. It was found that the tool porosity increases with increasing its structure number and decreasing hardness and size of grain.On the basis of obtained experimental data, an equation was compiled that reflects the power relationship between the porosity of a serial standard tool and its structural characteristics. By varying the structural characteristics of wheels, it is possible to determine the optimal porosity required for the grinding process in each concrete case.A comparison of experimental and calculated data on determining porosity of tools with different structural characteristics has shown that the difference in the values of porosity is within the range of 5 ÷ 8 %.Mathematical and statistical processing of experimental data, taking into account the dependence of the pore diameter on structural characteristics of the abrasive tool, allowed us to define a dependence of the pore size on the size of grain and porosity. The pore size grows with increasing size of grains and structure number and decreases with increasing hardness of the abrasive tool. The calculated pore size values differ from those experimentally obtained in the range of 5 – 12% with a confidence probability of 95 %.The presented calculation dependences and experimental data allowed authors to determine the porosity and the pore size of the tool through its GOST-normalized structural characteristics, as well as to make a rational choice of the tool for specified grinding modes and conditions.
A MODEL TO DEVELOP PEER FEEDBACK SKILLS IN FIRST-YEAR ENGINEERING STUDENTS

Published: August 2018

Abstract – Giving and receiving feedback is a necessary, but often difficult skill for young engineers to acquire. We developed and piloted the delivery of a feedback model as part of the first-year engineering experience at the University of British Columbia. The approach is based on recognizing feedback as a form of professional communication, and that it requires practice to improve. We wove different aspects of communication skill development through two large newly-designed first-year introduction to engineering courses, building towards face-to-face feedback through a staged series of communication experiences.
The full feedback model highlighted the nuances of face-to-face communication, and was called the "3×3", since it includes the three components involved in face-to-face feedback (sender, message, and receiver), each with three associated aspects. The sender uses appropriate words and body language, ensures proper interpretation, and is empathetic; the message is objective and non-judgmental, sufficiently detailed, and contains suggestions for improvement; and the receiver remains open and listening, acknowledges to the sender that they are listening, and clarifies to ensure understanding.
Students applied what they had learned through an activity reviewing poster presentations from a major course design project. In the activity, they each had an opportunity to craft a feedback message before delivering the message face-to-face to a peer. Students then reflected on the feedback they received by summarizing the message, recognizing how the sender delivered the feedback, and identifying why the feedback was helpful. Student reflections were analyzed for themes from the 3×3 model.
Students found feedback from peers particularly helpful when it was delivered in an appropriate and courteous manner, checked for proper interpretation, provided clear suggestions for improvement, and was coupled with praise of something that was done well.
Providing students with a structured model allows them to follow a process in both providing effective face-to-face feedback, but also better appreciate why receiving feedback is beneficial in helping them improve.
HELPING ENGINEERS DEVELOP AND EXERCISE CREATIVE MUSCLES
Authors: Pasek Zbigniew J. 
Published: August 2018

Abstract – A recent IBM-conducted survey of CEOs of multinational corporations indicated that creativity trumps other leadership characteristics. Across industries, organizations operate in increasingly complex and uncertain environments. Existing solutions are quickly exhausted or become obsolete, thus replacing them requires continuous innovation. Teaching existing solutions, the mainstay of formal education, is not enough. Students must learn how to consciously frame and reframe problems, create new knowledge and generate creative solutions on an ongoing basis. Most important, students must learn ways to motivate themselves to recognize and seek out problems as opportunities for generating creative solutions.
While in higher education importance of creativity is recognized, practical implementation of teaching it is still an afterthought or a sideline. While creativity as an academic subject is somewhat elusive, in particular in engineering education, recent accumulation of knowledge enables implementation of more systematic approaches.

Published: August 2018

Abstract – To address the new process of graduate attributes (GAs) assessment as required by the Canadian Engineering Accreditation Board (CEAB), the University of Waterloo (UW) employed six Graduate Attributes Lecturers (GALs) and four Accreditation Assistants (AAs) with a key role of leading the outcomes assessment process in each of the engineering departments. The GALs work collaboratively with each other and their departments to come up with a process of outcomes assessment. The collaboration methods and techniques used by the GALs in developing shared indicators for the common GAs are proving to be highly effective, and have led to significant progress. One of these methods is a structured brainstorming sessions for developing measurable performance indicators for the common GAs.
The following paper describes in detail the collaboration methods and techniques used by the GALs and AAs to develop shared indicators for the professional skills GAs. The paper also discusses the factors that proved to be successful in the whole process as well as the challenges faced by the team.
SHIFTING RESPONSIBILITIES: USING PEER ASSESSMENT IN SENIOR, ENGINEERING DESIGN TO PROVIDE EFFECTIVE SUPPORT AND MEANINGFUL FEEDBACK DESPITE LARGE CLASS SIZE
Authors: Bradford Andrea , Vale Julie 
Published: August 2018

Abstract – Urban Water Systems Design is a required, senior engineering design course for undergraduate students in the Water Resources and Environmental Engineering programs at the University of Guelph. A central component to this course has been a challenging, stormwater management design and simulation project. Recently, enrollment has increased from approximately 50 to 90 students. With these increased numbers, it is no longer feasible for the instructor to provide individualized, rich and robust feedback on the project. Rather than eliminating or simplifying the project, which is a highly valuable learning activity, peer assessment was investigated as an option.
In Fall 2016, peer assessment was implemented for two term tests and a design project. In addition to addressing resource constraints, this shift in responsibilities takes advantage of the active, collaborative, learning opportunities provided by grading tests in class and giving feedback to and receiving feedback from others on design work and report writing. To achieve the largest benefit possible, best practices suggested in the literature were followed, such as training peer assessors, including developing a rubric with the class to enhance understanding of expectations; using multiple assessors to address student concerns about fairness; and incorporating reflection on the peer assessment activities.
Data were collected through two surveys administered before and after the course’s peer evaluation activities and through graded reflections on peer evaluation activities. Most students thought they learned as much or more than they would have without the incorporation of peer evaluation. Based on predominantly positive student comments and fair grading, peer grading of tests will be used in future with a few minor modifications. Most students also found the peer assessment of design reports to be fair, with a reasonable time commitment. Some students were troubled by the variability of grades given by peers. Enhanced training was suggested to help students grade more consistently and provide more effective feedback.
Self Evaluation: Building Student Self-awareness and Competence
Authors: Lynch Denard 
Published: August 2018

This paper discusses the results of two experiments in self assessment and discusses their value in evaluating student consciousness of their competence, and the opportunity to improve self-awareness and competence in students. The data was gathered from two different engineering courses. The first experiment was conducted in a second-year course on basic electronics and electrical power. As part of the final examination, students were asked to assess their confidence in their answer to each question. The student self-assessment was compared to the actual result in an effort to determine the student’s perception of their competence. Student assessment was coded with respect to consciousness and competence.
The second experiment was performed on a midterm examination in engineering ethics and professionalism, a senior course discussing the impact and interaction of the engineering profession on society. Students were given an annotated exemplar and a marking rubric and asked to grade their own midterm submissions. The student assessments were compared to the instructor assessment and again the results were coded with respect to consciousness and competence.
The results showed a contrast between the second-year and senior courses. For the second-year course, 50.3% were coded as consciously competent or incompetent. In the senior course, 80% of students were coded as consciously competent.
The comparison of the two results suggest that senior students, given suitable instruction, are more aware of their competence than junior students suggesting that current methods do develop an improved awareness of competence, although other factors may be relevant. It is suggested that student awareness be formally monitored, and results used to modify pedagogy to improve and accelerate consciousness in graduates.

Published: August 2018

Abstract – The effectiveness of aerospace design engineering education has received a great deal of anecdotal feedback from its stakeholders. The aerospace industry, the Canadian government, the University, and the enrolled engineering students have expressed customer needs and expectations of design engineering training. While numerous curriculum reform initiatives have been developed and implemented, their impact has not yet beenstudied quantitatively. This paper proposes to use a theoretical model on design creativity, the statistical Q methodology, and an aerospace undergraduate capstone team case study to develop a tool for the quantitative evaluation for the effectiveness of aerospace design engineering education.

Published: August 2018

Abstract - This study represents the PhD thesis research of the lead author. The greater study is designed as a mixed-methods explanatory case study. The overarching objective is to explore whether the CEAB graduate attributes are emphasized in the engineering programs in the Faculty of Engineering at the University of Manitoba in the most optimal way. The first phase of the study is designed to determine the relative importance and the levels of dependencies of the graduate attributes across three engineering stakeholder groups: faculty, students, and industry members. In this paper, the design and methodology of the first phase of this mixed methods research study are explained, and the preliminary findings from the participation rates and participants’ familiarity with the graduate attributes on the survey data are presented. Results show that a sizable percentage of students, faculty and industry members are not highly familiar with the CEAB graduate attributes. Therefore, work to develop a common knowledge about the CEAB graduate attributes needs to continue.
FIRST-YEAR COMMON ENGINEERING CURRICULUM FOR THE BC POST-SECONDARY SECTOR
Authors: Dick Brian 
Published: August 2018

Abstract – Demand for engineering education has grown in recognition of its importance to the provincial economy, while engineering education capacity continues to lag. Engineering schools in British Columbia traditionally offer a common first-year of study that provides a foundation of science, mathematics, and engineering design before students specialize in second year. The British Columbia Council on Admission and Transfer (BCCAT) Engineering Articulation committee believed this transition served as a natural transfer point and undertook a year-long consultative process to establish the feasibility of developing a common, first-year engineering curriculum within the BC post-secondary sector.
This study found that although there exists some diversity within the first-year engineering programs at accredited receiving institutions, sufficient curriculum overlap allowed for a sector-wide common first-year engineering curriculum. This proposed curriculum suggests a content framework for students in all regions of the province to begin the first year of engineering studies at their institution of choice, and subsequently transfer to any of the major research institutions for degree completion.
STUDENT FEEDBACK AND PROBLEM DEVELOPMENT FOR WEBWORK IN A SECOND-YEAR MECHANICAL ENGINEERING PROGRAM
Authors: D'Entremont Agnes G. , Walls Patrick J. , Cripton Peter A. 
Published: August 2018

Abstract – WeBWorK is a widely-used open-source,
online homework tool where instructors may author their
own problems, or select problems from an Open Problem
Library. While it is extensively and globally used in
mathematics, there are few problems available for
engineering subjects. Due to initial student feedback
based on mathematics problems, we decided to compare
WeBWorK directly to our Blackboard Learn LMS for
online homework during an integrated second-year
Mechanical Engineering program.
Students were assigned two problem sets in
Blackboard and two problem sets in WeBWorK, and then
completed a survey. Results show a strong preference for
WeBWorK in all areas, including ease of use, ease of
navigation, clear feedback, reported enhancement of
learning, etc.
We outline the primary benefits and drawbacks of
using WeBWorK, and conclude by recommending
WeBWorK for online homework in engineering courses.
USING DESCRIBED AUDIO TOURS TO ENHANCE CONSTRUCTION ENGINEERING EDUCATION
Authors: McCabe Brenda Y. 
Published: August 2018

Abstract – In 2015, legislation was enacted to require mandatory ‘Working at Heights’ training for all construction workers in Ontario. While the legislation has been successful in reducing lost time injuries due to falls, it inadvertently raised barriers for engineering instructors wishing to give their students a field-related learning experience. Although construction management students completed WHMIS, safety awareness, and fall awareness training, the liability related to the risk of injury was sufficient to motivate construction companies to deny student requests to visit their sites. To adapt to the situation, a novel program of described audio tours was developed, thereby allowing students to visit and learn about different construction sites without jeopardizing their safety or the risk tolerance of hosting contractors. The resulting program improved the learning experience in that students visited 20 to 25 sites during the term instead of one.
SUPPORTING ENGINEERING STUDENT LEADERS TO INFLUENCE ORGANIZATIONAL CULTURE THROUGH A CO-CURRICULAR LEADERSHIP PROGRAM
Authors: Daniow Jordan , Klassen Mike 
Published: August 2018

Abstract – Engineering students develop leadership skills and identity through campus activities such as student government, clubs and design teams. We developed a program to enhance experiential learning of student club leaders related to organizational leadership. In this paper, we examine elements of this program related to the topic of organizational culture, a concept that has received little attention in engineering education. Students reported making use of program learning to implement and influence impactful structural and process changes in their organizations. This paper reports on the results of this teaching approach with hopes of informing and inspiring other leadership programs that aim to leverage the rich learning environment that student clubs provide.
Reviewing a decade of research on Engineering Leadership

Published: August 2018

Abstract – Academics, industry professionals, and policy makers across North America have shown increasing interest in the topic of engineering leadership. The demand from industries for engineers with diversified skills in a hypercompetitive market as well as the need to produce engineers attuned to the challenges of globalization are pushing universities to invest in engineering leadership education programs. In this context, this article engages with the following two questions: How have scholars addressed the concept of engineering leadership over the past decade? And how could the field of engineering leadership be constructively pursued in the future? The goal of this article is to map the structure of this nascent field by analyzing its scope, geography of application, methodology, relations, contradictions, gaps, and inconsistencies in the literature. By doing so, we explore reasons for the field’s structural particularities while also considering new avenues for future studies. We offer some tentative conclusions: articles predominantly presented the results of a pilot program or the outcomes of integration of leadership topics into current courses but in the process the concept of engineering leadership is seldom understood in a situated manner within wider shifts in economy and society. This points to a potential avenue for further research that incorporates a macro level of analysis that adopts a multi-dimensional view of leadership engineering.
