A Comparative Assessment of Students'Experiences in Two Instructional Formats of an Introductory Materials Science Course

An educational experiment at Worcester Polytechnic Institute is described in which the instruction of the Introduction to Materials Science course (ES2001) was modified to incorporate active and cooperative learning. The overall goal was simultaneously to enhance educational quality and faculty productivity. Aspects of the course modification included use of “active” rather than traditional lectures, assignment of students to cooperative learning teams, introduction of a “product dissection project,” and a “teacher as manager” approach to instruction, in which undergraduate Peer Learning Assistants and the graduate Teaching Assistant took on responsibilities as part of the instructional team. Data were gathered from 382 students in three traditional course offerings and two active/cooperative offerings, using various survey instruments to measure students' learning and performance, attitudes about learning, interest in materials science, and their satisfaction with the course.     

Student Learning of Criterion 3 (a)‐(k) Outcomes with Short Instructional Modules and the Relationship to Bloom's Taxonomy

Engineering accreditation criteria require that engineering graduates demonstrate competency with a set of skills identified in Criterion 3 (a)‐(k). Because of a scarcity of instructional material on many of these topics, a team of engineering instructors developed and tested a set of short modules for teaching these skills. Using before and after module surveys, the students indicated their confidence in their ability to do specific tasks derived from the module's learning objectives. Data also were obtained with a control group not receiving the instruction. In comparing pre‐ and post‐module data, 33 percent of the comparisons were significantly different at the 0.05 level. In comparing control and post‐module data, the corresponding value was 44 percent. These results indicate that instruction with these short modules produced a significant effect on student learning.     

The Effects of a First‐Year Engineering Design Course on Student Intellectual Development as Measured by the Perry Scheme

In response to the demand for enhanced design, problem‐solving, and team skills in engineering graduates, Penn State has instituted a number ofteam‐based, project‐learning courses, including one taken by nearly every first‐year engineering student. To determine the impact of these experiences on our students we have begun a cross‐sectional and longitudinal study of their intellectual development based upon the Perry model. In this paper, we describe the research methodology and results for the initial group of first‐year students interviewed. The results of the study include the effects on intellectual development of the first‐year design course, gender, honors status, and the students' academic ability as indicated by SAT scores and grade point average. Design experience was positively related to enhanced intellectual development. Honors status, gender, and academic ability were not significantly related to Perry rating. We discuss the implications of these findings for instruction and curricular reform.     

Increasing Student Awareness of Ethical,Social, Legal,and Economic Implications of Technology

The accreditation criteria for engineering programs require that the curriculum introduce students to the ethical, social, economic and safety issues arising from the practice of engineering. Graduates must also demonstrate competence in written and oral communication skills. This paper describes a bioengineering course we developed at Arizona State University to satisfy these criteria and also meet the literacy and critical inquiry requirement of the university. The primary goal of the course is to increase the students' awareness of the global “societal” issues arising from the development and use of bioengineering technology. Secondary goals include improvement of skills in literacy and critical inquiry, oral communication, and teaming. We use cooperative learning to ensure student participation, creative controversy to stimulate interest in the topics being discussed, and TQM tools to enhance team performance. This paper describes the course content, its organization and structure, the methods used to assess student performance, and the strategies we use to facilitate learning. We also discuss how students have reacted to the course and our experiences in delivering the course.     

Interdisciplinary Collaborative Learning in Mechatronics at Bucknell University

Examination of the “cone of learning” shows an increase in retention when students are actively engaged in the learning process. Mechatronics is loosely defined as the application of mechanical engineering, electrical engineering, and computer intelligence to the design of products or systems. By its nature, mechatronics is an activity‐oriented course. The course content also provides an opportunity to employ interdisciplinary collaborative learning with active learning techniques. The mechatronics course at Bucknell consists of mechanical and electrical engineering students at the senior and graduate levels. The students engage in a variety of activities in teams comprised of members from each of these groups. In addition to team laboratory exercises and homework assignments, the students work in interdisciplinary groups to process their efforts. That is, they engage in meaningful discussion among themselves concerning their activities and the implications of the various results. The students also act as teachers by preparing lectures and exercises on topics from their discipline to the students in the cross discipline. Specifically, the electrical engineers teach the mechanical engineers microcontrollers, and the mechanical engineers teach the electrical engineers mechanisms. This paper describes the learning techniques employed in this course, as well as the interpretation of the results from the students. It also discusses the relationship of the course outcomes to Criterion 3 of the engineering accreditation criteria promulgated by the Engineering Accreditation Commission of the Accreditation Board for Engineering and Technology (EAC/ABET).     

A Longitudinal Study of Engineering Student Performance and Retention. IV. Instructional Methods

As part of an ongoing longitudinal study, the author taught five chemical engineering courses in consecutive semesters to a cohort of students, using cooperative learning and other instructional methods designed to address a broad spectrum of learning styles. This paper outlines the policies and procedures, assignments, and classroom activities in the experimental course sequence and describes the students' performance and attitudes as they progressed through the sequence. The results suggest that active and cooperative learning methods facilitate both learning and a variety of interpersonal and thinking skills, and that while these methods may initially provoke student resistance, the resistance can be overcome if the methods are implemented with care.     

A Multimodal Exploration of Engineering Students' Emotions and Electrodermal Activity in Design Activities

Background

This exploratory study uses multimodal approaches to explore undergraduate student engagement via topic emotions and electrodermal activity (EDA) in different engineering design method activities and with different instructional delivery formats (e.g., lecture vs. active learning).

Purpose/Hypothesis

The goal of this research is to improve our understanding of how students respond, via engagement, to their engineering design activities during class. This study hypothesizes that students would experience no self‐reported mean changes in topic emotions from their preassessment scores for each engineering design topic and instructional format nor would electrodermal activities (EDA) associate to these topic emotions throughout the design activities.

Design/Method

Eighty‐eight freshmen engineering students completed online pretopic and posttopic emotions surveys for five engineering design activities. A subset of 14–18 participants, the focal point of this study, wore an EDA sensor while completing the surveys and participating in these sessions.

Results

Preliminary findings suggest that EDA increased for individual and collaborative active learning activities compared to lectures. No significant changes in EDA were found between individual and collaborative active learning activities. Moderate negative correlations were found between EDA and negative topic emotions in the first engineering design activity but not across the rest. At the end of the semester, active learning activities showed higher effect sizes indicating a re‐enforcement of students' engagement in the engineering design method activities.

Conclusion

This study provides initial results showing how multimodal approaches can help researchers understand students' closer‐to‐real‐time engagement in engineering design topics and instructional delivery formats.     

Renewal of a Flagging Environmental Engineering Program: Start at the Beginning

Abstract Environmental engineering is in popular demand with students and employers. Despite the demand, the environmental engineering program at the University of Missouri-Rolla (UMR) had declined in recent years. A concerted effort is now being made to improve the attractiveness and quality of UMR's program, beginning with the introductory environmental engineering course offered by the Civil Engineering Department. An experimental section of the introductory course offered in the 1994 spring semester used a semester-long design project, team exercises, field trips and imaginative demonstrations, active learning strategies, and extensive discussions of environmental engineering practice to improve student learning and interest. Results were encouraging. Students performed well and gave the course good evaluations; interest in the environmental program appears to be on the upswing.     

Quality Improvement Partnerships with Industry Using Student Teams

The 1993 Quality Challenge is a cooperative partnership between Milliken and Company, the National Science Foundation and three North Carolina Universities. The project goal was to activate a multidisciplinary team of students, faculty, and industry representatives in a real-world quality improvement project. The 1993 project was an expanded follow-up to the 1992 University Challenge Project, also sponsored by Milliken. Based upon past experience, project coordinators broke the 1993 project into three components: Preparation, Identification, and Action. Preparation included a preliminary course held in the Spring to teach students fundamental Total Quality Management tools, team building skills and communication skills needed in industry. A team of students was selected from the course to participate in the summer Identification and Action phases of the project. The Identification phase included introduction to project goals, team process training, specialized team formation and project focus. The Action phase of the project included process capability studies, shade variation studies, root cause trials and a statistical design of experiment on shade variables. The project resulted in many recommendations to improve the process and reduce shade variation. The overall project methodology and approach can be applied to industries other than textile manufacturing. Educational benefits for all participants included: team building and teamwork experience, enhancement of effective communication skills, experience in design of experiments, engineering design and practice, greater self confidence, and industrial experience with real-world quality improvement opportunities.     

Ethics Exercises for Civil,Environmental, and Geological Engineers

The practices of civil, environmental, and geological engineering share many common ethical dilemmas. These fields typically require extensive interaction with clients and regulatory agencies, while dealing with unpredictable earth materials for design and uncertain design parameters. Consequently, a capstone design course must address not only technical issues, but also a wide range of ethical and behavioral issues. This study presents a series of exercises used in the classroom to teach these issues through dealing with “gray” ethical areas, concepts of advocacy and the use of compromise, relating specific stories to global concepts, proper behavior in the corporate environment, and the influence of corporate culture on ethical decisions. The exercises were designed to incorporate a variety of active learning styles, including individual and group writing, group short answer, group design, and role playing as an individual and as part of a team. Only a small commitment of class time is required to complete these exercises, roughly six lecture periods and one laboratory period.     

A New Senior Level Course in International Design

The internationalization of the design arena is incontestable. Although many engineering design educators support the idea of incorporating international design issues into engineering design courses, only a few engineering design programs appear to actually give proper consideration to these topics. We recently originated and developed a course entitled “International Design,” which we first team-taught in the Spring of 1997 at the Kanazawa Institute of Technology in Ishikawa, Japan. The course, open to senior and graduate students of various engineering disciplines, featured lectures and a quarter long team design project. The philosophy and contents of the course are presented in this paper.     

The Effects of Personality Type on Engineering Student Performance and Attitudes

The Myers‐Briggs Type Indicator® (MBTI) was administered to a group of 116 students taking the introductory chemical engineering course at North Carolina State University. That course and four subsequent chemical engineering courses were taught in a manner that emphasized active and cooperative learning and inductive presentation of course material. Type differences in various academic performance measures and attitudes were noted as the students progressed through the curriculum. The observations were generally consistent with the predictions of type theory, and the experimental instructional approach appeared to improve the performance of MBTI types (extraverts, sensors, and feelers) found in previous studies to be disadvantaged in the engineering curriculum. The conclusion is that the MBTI is a useful tool for helping engineering instructors and advisors to understand their students and to design instruction that can benefit all of them.     

After So Much Effort: Is Faculty Using Cooperative Learning in the Classroom?

Cooperative learning (CL) has been lauded over the years as one of the most successful teaching/learning strategies employed by professors of science, mathematics, engineering and technology (SMET) in institutions of higher education throughout Puerto Rico. The goal of the research project presented here was to examine the effectiveness of CL as perceived by SMET faculty who use it in the classroom at member institutions of the Puerto Rico Louis Stokes Alliance for Minority Participation (PR‐LSAMP). As a long‐term goal, PR‐LSAMP researchers desired to use the findings to understand and address the training needs of their SMET faculty. Data was gathered on faculty members' use of CL and their perceptions of the effect of CL strategies on student performance and attitudes. Principal survey results showed that over 60% of faculty felt confident in their knowledge of CL theory and role assignment, although somewhat less confident in conflict resolution, grading activities and individual accountability. Fifty percent (50%) reported using the strategy very often or often (primarily for the exploration and learning of new concepts, in team projects and presentations, and in quizzes). Forty‐one percent (41%) described their experience in implementing CL as excellent or very good. In addition, faculty perceived more positive than negative changes in student performance and attitudes. Based on study results, researchers concluded that the success of cooperative learning in PR‐LSAMP institutions signals the beginning of a paradigm shift in the islands' educational system. In addition, results of the study were subsequently used to develop a cadre of SMET faculty to train their peers in various areas of cooperative learning.     

Identification of Dysfunctional Cooperative Learning Teams Based on Students' Academic Achievement

Background Considerable evidence exists to suggest that students who study cooperatively reap significant benefits in terms of their learning performance. However, sooner or later, most cooperative learning teams have to deal with one or more members whose actions disturb the team. Unless these problems are quickly resolved, the cooperative learning team gradually becomes dysfunctional and the benefits of cooperative learning are diminished. Purpose (Hypothesis ) A method is proposed for identifying dysfunctional cooperative learning teams by comparing the academic achievement of students in a cooperative learning condition with that of students in an individual learning condition. Design /Method A series of experiments were performed in which 42 sophomore mechanical engineering students were randomly assigned to the two learning conditions and were formed into mixed‐ability groups comprising three team members. The academic performance of the students in the two learning conditions was then systematically compared in terms of their respective test scores. Results Dysfunctional teams were identified using a new quality index defined as the mean test score of the team divided by the standard deviation of the team members' test scores. The probability of a Type I error was quantified using a control chart. The identification results were verified by analyzing the students' off‐task behavior frequency and attitudes toward cooperative learning, respectively. Conclusions The experimental results confirm that the proposed quality index is a potential indicator of dysfunctional cooperative learning teams.     

Developing Aspiring Engineers into Budding Entrepreneurs: An Invention and Innovation Course*

Our invention and innovation course for engineering students cultivates an understanding of the entrepreneurship and invention world through a hands‐on introduction to product design and development. A pervasive emphasis on team dynamics as well as on the processes of design, invention and innovation fosters an environment that produces successful teams and inventions. This paper describes objectives and components of the elective course, development of high‐performance invention teams, course evaluation, assessment tools and results, and lessons learned. Students working in teams design and build an invention of their choice, and explore entrepreneurial topics such as profitability, marketing, sources for capital, and patenting. Creating business feasibility studies leads each team to estimate the manufacturing cost of their product and forecast potential sales revenues and profits. A two‐week, low‐risk introductory creativity and design project provides an early opportunity for creative expression, as well as insight into individuals' contribution and effectiveness in a team environment. Our course was inspired and initially supported by the National Collegiate Inventors and Innovators Alliance (NCIIA). Some student teams have subsequently received NCIIA product development funding.     

Retention 101: Where Robots Go … Students Follow

At Indiana University—Purdue University Fort Wayne we have developed ETCS 101—Introduction to Engineering, Technology, and Computer Science, a freshman success course for students in the School of Engineering, Technology, and Computer Science. The main objective of this course is to increase retention. The course aims to provide students with sufficient computer and personal development skills and to help them develop the right mental attitude conducive for academic success. Features of the course include projects of software and hardware nature, extensive use of the Internet and Web software tools, and a team‐teaching format. As the main project of this course, small teams of students design, build, program, and test an autonomous mobile robot using LEGO® parts, sensors, and the Robotic Command eXplorer (RCX) controller. This is a multidisciplinary, project‐driven learning process that encourages students to develop problem solving and teamwork skills and fosters their creativity and logic.     

Teaching Design to Freshmen: Style and Content

This paper describe a freshman course in engineering design that stresses the open-ended and ill-structured nature of design in a project-based context. The projects are chosen in part for their social context and utility. The projects are supplemented by lectures on design methodology and other topics related to engineering practice. Among the deliverables required of the students are proposals, progress reports, and written and oral presentations—the latter to an external design jury as part of a design competition.     

Educational Innovations in Multimedia Systems*

Multimedia systems have emerged as one of the fastest growing segments of computing systems and thus need to be well integrated into a computer engineering curriculum. Fortunately the teaching and learning of multimedia systems can be aided with novel instructional techniques based on multimedia. The Multimedia Curriculum project at the University of Massachusetts Amherst is developing a unified set of instructional materials on the engineering techniques used in the design and test of hardware, software and networks for multimedia. This large project includes three facets: 1) multimedia instructional modules using web‐linked Digital Video Disks, 2) multimedia communication utilities to facilitate student interaction, and 3) multimedia component design projects. In this paper, we explain our approach to using multimedia as both content and instructional technology and briefly present preliminary results in each of the three facets.     

Hands‐On,Minds‐On Electric Power Education*

ABET Engineering Criteria 2000 has encouraged changes in engineering education. The deregulation of the electric power industry is also causing changes in the types of jobs power engineers take upon graduation. This paper describes efforts by power faculty at Kansas State University to provide students more hands‐on active learning experience with power systems and machinery. A summary of the power curriculum is provided. The courses affected include an energy conversion course required of all electrical engineering students, and a new power laboratory course required of students taking the electric power option. Examples of student assignments are provided. Observations and discussion of the in‐class experiences are provided. The paper describes work done and in progress to convert the traditional power courses into studio‐type courses in which instruction can flow from lecture to laboratory to computer demonstration formats with ease. Future plans for the project are also discussed.     

An Introduction to Engineering Through an Integrated Reverse Engineering and Design Graphics Project

This paper discusses a new freshman course that merges previous topics in the “Introduction to Mechanical Engineering” and “Engineering Design Graphics” courses into a single integrated teaching effort. The main objective of the new course is to introduce students to mechanical engineering education and practice through lectures and laboratory experiences. A major effort in the course is devoted to a reverse engineering team project. The students are divided into four‐member teams and are instructed to select a simple mechanical assembly for dissection. They study and disassemble their object into basic constituent components, documenting this process with freehand sketches and notes. They use these sketches and other measured dimensions to construct 3‐D solid computer models of each major component. The teams then obtain .STL files of the solid models, which are used to make rapid physical prototypes of their parts. The teams conclude their project activities by generating engineering drawings directly from the 3‐D geometric data base. All of these efforts are integrated, documented, and submitted to the instructor as a final team project report.
