Computer simulation and animation (CSA) has been receiving growing attention and wide application in the engineering education community. The goal of this dissertation research was to improve students' conceptual understanding and procedural skills for solving particle dynamics problems, by developing, implementing and assessing 12 interactive computer simulation and animation learning modules. The developed CSA learning modules integrate visualization with mathematical modeling to help students directly connect engineering dynamics with mathematics. These CSA modules provide a constructivist environment where students can study physical laws, demonstrate mental models, make predictions, derive conclusions, and solve problems. A mixed-method research was conducted in this study: quasi-experimental method (quantitative), and survey questionnaires and interviews (qualitative and quantitative). Quasi-experimental research involving an intervention group and a comparison group was performed to investigate the extent that the developed CSA learning modules improved students' conceptual understanding and procedural skills in solving particle dynamics problems. Surveys and interviews were administrated to examine students' learning attitudes toward and experiences with the developed CSA learning modules. The results of quasi-experimental research show that the 12 CSA learning modules developed for this study increased students' class-average conceptual and procedural learning gains by 29% and 40%, respectively. Therefore, these developed CSA modules significantly improved students' conceptual understanding and procedural skills for solving particle dynamics problems. The survey and interview results show that students had a positive experience with CSA learning.

This research is an exploratory study into gender dynamics in an engineering classroom in a Faculty of Engineering at an Australian University. It has concentrated on understanding and presenting students perceptions of their learning environment in an engineering classroom and their experiences within it to determine the extent to which gender affects different classroom experiences. A first year engineering subject ‘Introduction to Engineering Computing’ was the environment used for this study. The research employed an ethnographic research methodology drawing on semi-structured interviews and observations. It also used surveys to triangulate the data for improved reliability and validity. Gender has clearly been highlighted as a determinant of students’ experiences from a students’ perspective in an engineering classroom. The most noticeable differences between female and male student experiences found in this study stemmed from four factors: their previous experiences; their learning approaches; the language used within the classroom and the lack of role models. In these areas there were found to be various levels of advantage and disadvantage experienced by women and men. These are presented in Chapter 5 & 6 of this thesis. The resulting understanding begins the process of providing a framework in which strategies can be developed to more effectively engage female and male students in engineering education. / Masters Thesis

Information Technology (IT) systems have become essential components of our society. These IT systems have an internal structure called the system's architecture. This architecture directly affects the system's performance and ability to meet business objectives. The people who design this structure are called IT Architects. Investigating the capabilities that distinguish highly-skilled IT Architects contributes to IT knowledge and practice and supports improving the design of systems' architectures as well as the selection and development of IT Architects. This thesis examines some of the capabilities that distinguish highly-skilled IT Architects and applies the resulting understanding to the education of post-graduate IT students. By investigating selected capabilities of highly-skilled IT Architects, how this group of IT Architects differ from their colleagues with respect to highly-valued capabilities and how these capabilities could be taught, we clarify both a professional and an educational basis for improvement. The research has a three stage, multi-method design. The initial stage, undertaken in 2004, consists of interview-based qualitative research with fourteen practicing IT Architects to understand the characteristics of highly-skilled IT Architects. The interviewees were chosen through personal relationships and subsequent snowball sampling and through the interviews and subsequent analysis, we identify eight capabilities, four personality traits and a range of experience that is valuable for highly-skilled IT Architects. These results support prior research that identified the importance of communications and business knowledge while extending the range of valuable characteristics for the IT Architect role. The next quantitative stage surveys 82 practicing IT Architects and 97 other IT professionals using four psychological measures; the Cognitive Style Inventory (CSI), the Problem Solving Inventory (PSI), the Vividness of Visual Imagery Questionnaire (VVIQ), and Zimbardo's Time Perspective Inventory (ZTPI). The analysis, undertaken in 2005, identifies two statistically significant differentiating capabilities that distinguish highly-skilled IT Architects from less skilled IT Architects. The first capability is that the highly-skilled IT Architects approach problems differently and generate more alternatives before attempting solutions and spend more effort evaluating outcomes than the less skilled IT Architects. The second capability is that the less skilled IT Architects have a different attitude towards time and do not always act consistently with a longer term perspective. The final stage of research investigates whether the teaching of material related to the two distinguishing capabilities improve students outcomes for these capabilities. In 2006 we measured the initial student capability level of 35 students, the level of 28 of these students at the conclusion of the subject, and again in 2007, one-year later 16 students were measured. We again use quantitative surveys with the PSI and ZTPI instruments and found that whilst we measure a change in student capability for problem solving, the two capabilities we targeted are not significantly affected through the teaching. Interviews with the participants indicate that the teaching is effective and the lack of significant differences in the targeted capabilities is because of external factors overriding what they are learning. Our research contributes to the field of Computer Science and Information Technology by providing: (i) the basis for improved identification and selection of IT Architects for industry and providing additional information to enhance their professional education through the identification of distinguishing capabilities of highly-skilled IT Architects; (ii) information for educators about IT Architect capabilities and capability development that are important for highly-skilled IT Architects and some considerations when teaching these capabilities; (iii) a foundation for research that compares and contrasts capabilities within other IT professions; and (iv) results that can be used to improve the process of architecting IT systems. More generally, the research contributes to the body of knowledge regarding IT skills and requirements for different roles.

In both engineering and physics education, a common objective is that students should learn to use theories and models in order to understand the relation between theories and models, and objects and events, and to develop holistic, conceptual knowledge. During lab-work, students are expected to use, or learn to use, symbolic and physical tools (such as concepts, theories, models, representations, inscriptions, mathematics, instruments and devices) in order both to understand the phenomena being studied, and to develop the skills and abilities to use the tools themselves. We have earlier argued that this learning should be seen as the learning of a complex concept, i.e. a “concept” that makes up a holistic system of “single” interrelated “concepts” (i.e. a whole made up of interrelated parts). On the contrary, however, in education research it is common to investigate “misconceptions” of “single concepts”. In this paper we will show the power of analysing engineering students’ learning as the learning of a complex concept. In this model “single concepts” are illustrated as nodes or “islands” that may be connected by links, while the links that students actually make are represented by arrows. The nodes in our model are found by looking for “gaps” in the actions and conversations of students. A gap corre­sponds to a non-established link, and when a gap is filled and the students establish a relation between two nodes, this is represented by a link. The more links that are made, the more complete the knowledge. In this study we report an analysis of a sequence of labs about AC-electricity in an electric circuit theory course. In for example electric circuit theory the “concepts” of current, voltage and impedance are interdependent. Rather, the central physical phenomenon is “electricity” represented by Ohms law as a generalization of the current/voltage/impedance/frequency-relationship of a circuit or circuit element. The results show the learning of “electricity” as a complex concept with students’ knowledge becoming more complete. Furthermore, according to our analysis “entities” that in later labs were fused into one were separate in the earlier labs. For example in a later lab we could note that “the physical circuit” and “the circuit drawing” had fused into a single “real circuit”. Our results suggest that the learning of a complex concept first start with establishing more and more links. As links become well established, “entities” that have been separate fuse into a whole. Our model suggests a method for finding “learning difficulties” since these corresponds to “gaps” and non-established links. As teachers and experts in a field we can miss to uncover these since for us the ‘complex concept’ has become a conceptual whole and we may no longer be able to distinguish the parts in the complex. In line with the thesis of M. Holmberg we also argue that learning problems in electric circuit theory may be due to the common failure to appreciate that concepts are relations.

Women of color, specifically African American women, within science, technology, engineering, and math (STEM) are significantly underrepresented in workplace organizations. However, the majority of the research addressing STEM issues is centered on increasing the pipeline, recruitment, and retention of underrepresented groups in the K-12 and collegiate domain. There is little, if any, literature focused on the career development of African American female engineers holistically. This is a critical missing link in the research which would support efforts to increase diversity in STEM. The purpose of this study was to provide this missing link by examining the career experiences of African American female engineers and exploring their challenges and support systems during their career development. This qualitative study was guided by the basic interpretive inquiry utilizing a life history approach. There were nine African American female participants in the study who currently work in an engineering field within an engineering industry. Data were obtained using in-depth interviewing where the participants were digitally recorded and the files were transcribed verbatim. The data were analyzed using thematic analysis.

This qualitative study sought to describe and understand the experiences of female students attending engineering colleges in Mexico and the sources of support and strategies that helped them persist in their programs. The participants were 20 women engineering students enrolled in at least their third year in selected colleges of engineering in Mexico, in both public and private universities, and pursuing a variety of engineering majors. Findings focus on the experiences of female students that helped them stay in their programs. Participants described their experiences in college as very challenging and perceived the environment as hostile and uncertain. In addition, patriarchal Mexican cultural values and stereotypes were identified by students as influencing and helping shape the engineering environment. However, in this context, participants were able to find sources of support and use strategies that helped them remain in their majors, such as a strong desire to succeed, a perceived academic self-ability; and support from their families, peers, institutions, and?most importantly?their professors. Furthermore, the fact that participants were able to persist in their programs gave them a sense of pride and satisfaction that was shared by their families, peers, and faculty. In addition, participants experienced contradictory forces and were constantly negotiating between rejecting traditional gender norms and upholding the norms that are so deeply engrained in Mexican society. Finally, as the students advanced in their programs and became ?accepted to the club,? they tended to reproduce the maledominated value system present in engineering colleges accepting their professors? expectations of being ?top students,? accepting the elitist culture of engineering superiority, and embracing the protection given by their male peers. Retention of Mexican female engineering students is important for all engineering colleges, but cultural factors must be taken into consideration. The dominance of machismo attitudes and values in Mexican culture present specific challenges to achieve an environment more supportive of women in Mexican engineering colleges. Institutions need to be proactive and creative in order to help faculty and administrators provide an environment in which female engineering students can be successful.

Online discussion forums and reflective writing are proven methods for enriching conceptual understanding and are hallmarks of engineering education. Plagiarism and many students’ apprehension to contribute to online journals can plague the effectiveness of these educational tools. Using elements of the engineering design cycle, I have created a blogging website that addresses these problems by restricting comment visibilities for users and includes a graphic visualization called a “word cloud” to supplement discussion. A prototype was tested with UTeach Engineering teachers for feedback on design and use. The critiques provided examples of classroom use, constructive design feedback, and ideas for its use as a formative assessment. The design could be used as a pedagogical tool for an investigation of formative assessments in engineering education, but further research for “word cloud” visualizations and journal data collection is needed to expand the current design. / text

This thesis describes a method for measuring the innovation capabilities of mechanical engineering students and presents the results of a yearlong experiment. A review of relevant literature shows that it is unclear whether the innovation capabilities of engineering students increase or decrease over time. Experiments were conducted at two universities in which students were asked to redesign an everyday electromechanical product in a sketch-based concept generation activity. Student participants were also asked to complete a self-efficacy survey. Nearly one thousand concepts were generated from a combination of freshmen and seniors. The concepts were evaluated for originality, technical feasibility, and innovation characteristics by multiple raters. At both schools, the findings suggest that the senior-level engineering students are more creative than their freshman-level counterparts without sacrificing technical feasibility. Additionally, the seniors rated higher for originality at the end of the semester than they scored prior to taking their senior design class. These results suggest that the mechanical engineering curricula, and especially the senior-level Engineering Design courses, are having a positive effect on student creativity. / text

Technology-enhanced instruction has a great potential to support the learning process. However, the engaging power of technology can become a distracting factor if it is not deployed properly. Unfortunately, the current literature in instructional design and user interface design is broad and not easily accessible by construction faculty. This dissertation presents a framework to guide the development of technology-assisted instruction for the classroom. The framework developed is called EDDE which stands for four conceptual steps involved in the creation of a technology-supported teaching tool: Explore, Design, Develop, and Evaluate. EDDE contains a novel synthesis of the literature in instructional design and user interface design as well as survey data of student subject matter knowledge and information technology background. A computerized tool called EDDEaid makes accessible the large store of knowledge supporting EDDE. Assessment of EDDEaid is presented with evaluation results from nine university faculty that teach construction subjects as well as through critique of and changes to an existing interactive learning tool. EDDE and EDDEaid are found to contribute to the body of knowledge regarding the deployment of technology-enhanced instruction and provide support to construction faculty developing learning tools. / text

There are many opportunities to use engineering skills to improve the conditions for mar-ginalized communities, but our current engineering education praxis does not instruct on how engineering can be a force for human development. In a time of great inequality and exploitation, the desire to work with the impoverished is prevalent, and it has been proposed to adjust the engineering curriculum to include a larger focus on human needs. This proposed curriculum philosophy is called humanitarian engineering. Professional engineers have played an important role in the modern history of power, wealth, economic development, war, and industrialization; they have also contributed to infrastructure, sanitation, and energy sources necessary to meet human need. Engineers are currently at an important point in time when they must look back on their history in order to be more clear about how to move forward. The changing role of the engineer in history puts into context the call for a more balanced, community-centred engineering curriculum. Qualitative, phenomenographic research was conducted in order to understand the need, opportunity, benefits, and limitations of a proposed humanitarian engineering curriculum. The potential role of the engineer in marginalized communities and details regarding what a humanitarian engineering program could look like were also investigated. Thirty-two semi-structured research interviews were conducted in Canada and Ghana in order to collect a pool of understanding before a phenomenographic analysis resulted in five distinct outcome spaces. The data suggests that an effective curriculum design will include teaching technical skills in conjunction with instructing about issues of social justice, social location, cultural awareness, root causes of marginalization, a broader understanding of technology, and unlearning many elements about the role of the engineer and the dominant economic/political ideology. Cross-cultural engineering development placements are a valuable pedagogical experience but risk benefiting the student disproportionately more than the receiving community. Local development placements offer different rewards and liabilities. To conclude, a major adjustment in engineering curriculum to address human development is appropriate and this new curriculum should include both local and international placements. However, the great force of altruism must be directed towards creating meaningful and lasting change. / Thesis (Ph.D, Civil Engineering) -- Queen's University, 2008-08-25 09:04:54.722
