A longitudinal evaluation of a project-based learning initiative in an engineering undergraduate programme

Project-based learning (PBL) is a well-known student-centred methodology for engineering design education. The methodology claims to offer a number of educational benefits. This paper evaluates the student perceptions of the initial and second offering of a first-year design unit at Griffith University in Australia. It builds on an earlier evaluation conducted after the initial offering of the unit. It considers the implementation of the recommended changes. Evaluations of the two offerings reveal that students (in both the initial and second offering) generally enjoyed the experience, but that the second offering was found to be a significantly more enjoyable learning experience. Students in the second offering also reported a significantly better understanding of what they needed to do for the design projects and where to find the requisite information. The oral presentation aspect of the initial and second offerings received the lowest satisfaction rating. The inclusion (and delivery) of the computer-aided drawing component of the unit is seen as a positive aspect by some students, but many others comment on it negatively. The best aspects of the PBL unit and those aspects needing further improvement were similar to the findings of other investigations documented in the literature.     

An evaluation of a project-based learning initiative in engineering education

Project-based learning (PBL) is a well-known methodology for engineering design education due to a number of benefits it is claimed to offer. This paper presents the initial offering of a first-year engineering PBL unit at Griffith University in Australia. An evaluation of student perceptions of the unit revealed that students generally enjoyed the experience, with the oral presentation aspect receiving the lowest satisfaction rating. There was no significant difference in the ratings between any demographic grouping, suggesting that all students were able to participate in, and experience, the unit in essentially the same way. The best aspects of the unit and those aspects needing improvement were similar to the findings of other investigations documented in the literature. It is proposed that future offerings of the unit will reduce the number of design projects from three to two per semester and will attempt more sophisticated individualisation of marks for group work activities.     

Project-based learning in engineering design in Bulgaria: expectations,experiments and results

Using a students’ workshop as a laboratory, this article summarises the observation of three years’ implementation of a new study module for a Bachelor Program in Engineering Design (Interior and Furniture Design) at the University of Forestry, Sofia, Bulgaria. The article offers an analysis of group dynamics and the difficulties and issues observed during the process. Data from survey questionnaires are interpreted; proposals are made for future research. The conclusion of the authors includes the following points: positive response by students, important encounter with successful professionals and companies; creative fulfilment and experience of team work. On the weak side is the experienced discomfort in public presentation, lack of verbal and graphic skills, interpersonal issues and pressure of real requirements from teachers and company; lack of adequate attention by the tutors. The need of better understanding a team ‘code’ of behaviour and preparation for an active learning method was felt. A proposal leading to a mixed-team organisation for better support of first-time participants in the module is made.     

Case study of a problem-based learning course of project management for senior engineering students

The analysis of the current state of the Ukrainian system of engineering education indicates the prevalence of traditional teaching–learning approaches in contrast to the modern needs of the labour market. Many universities across the world use the problem/project-based learning (PBL) which is an effective approach for the development of design and management skills of engineering students. The paper describes a detailed structure of a PBL course in project management and practical experience related to its implementation in an engineering degree programme at Bohdan Khmelnytsky National University of Cherkasy. Also, the results of surveys carried out in order to study the students’ generic competences’ development and perception of the PBL process are presented. The results show that students understand the diversity of PBL aspects and the influence of the PBL approach on their professional characteristics such as teamwork, ability of self-directed learning, communication and problem-solving skills.     

Using an evidential reasoning approach for portfolio assessments in a project-based learning engineering design course

The purpose of this study is to analyse the feasibility of an evidential reasoning (ER) method for portfolio assessments and comparison of the results found with those based on a traditional holistic judgement. An ER approach has been incorporated into portfolio assessment of an undergraduate engineering design course delivered as a project-based learning (PBL) course and the calculated utility interval means of the student results compared with weighted rubric means based on a traditional holistic judgement. The findings show the ER method superior to the traditional holistic judgement in that ER is capable of incorporating, firstly, assessors' ignorance of information concerning the portfolio development and content and, secondly, incomplete portfolio information. The ER approach is a commendable alternative to traditional holistic judgement of PBL portfolios, since it provides additional information, increases accuracy and is easier to use.     

Meta-assessment in a project-based systems engineering course

Project-based learning (PBL) facilitates significant learning, but it poses a major assessment challenge for assessing individual content knowledge. We developed and implemented an assessment approach and tool for a mandatory undergraduate systems engineering PBL-based course. We call this type of assessment student-oriented meta-assessment. Research participants included 131 undergraduate engineering students who carried out team projects requiring conceptual modelling of complex systems. Next, individual students assessed their peer team projects. Finally, the course staff assessed students individually, based on the content knowledge that was reflected in students’ comments to their peers, by using the new meta-assessment tool. The research findings validated the meta-assessment tool which can serve for assessing various PBL courses. Our contribution is twofold: a new approach for assessing project-based undergraduate engineering courses, and classification of meta-assessment methods into three types, where a student-oriented meta-assessment as one of the three meta-assessment methods is our newly introduced and validated method.     

Design and implementation of a project-based active/cooperative engineering design course for freshmen

A project-based active/cooperative design course is planned, implemented, assessed and evaluated to achieve several desired engineering outcomes. The course allows freshman-level students to gain professional hands-on engineering design experience through an opportunity to practise teamwork, quality principles, communication skills, life-long learning, realistic constraints and awareness of current domestic and global challenges. Throughout successive design reports and in-class assignments, the students are required by the end of the semester to communicate, clearly and concisely, the details of their design both orally and in writing through a functional artefact/prototype, a design notebook, an A0 project poster and a final oral presentation. In addition to these direct assessment tools, several indirect measures are used to ensure triangulation. Assignments are based on customer expectations using a detailed checklist. This paper shows the direct and indirect assessment tools that indicated a high level of achievement of course learning outcomes and a high level of student satisfaction.     

Introducing a project-based assignment in a traditionally taught engineering course

This study seeks to explore whether a combination of traditional teaching methods with project-based learning (PBL) activities can improve the student learning experience in an engineering course of soil mechanics. As an alternative to the traditional type of assignment that consisted of several textbook problems, a project-based assignment was introduced in 2015 so that students could work on real-world geotechnical problems throughout the whole semester. Students were permitted to choose whether they would undertake the project-based assignment or the traditional one, thus forming the ‘project’ and ‘non-project’ groups, respectively. The academic performance of these two groups was compared on the basis of student marks while the student experience was evaluated through a series of interviews. The data collected over 3 years indicated that students from both groups had very similar academic performances; however, the students who completed the project-based assignment reported better engagement in the learning process as they enjoyed the opportunity to experience the practical aspects of soil mechanics. The obtained results also revealed low motivation among students to embrace new learning approaches such as PBL, as the majority of them preferred more traditional methods of teaching.     

Collaborative project-based learning: an integrative science and technological education project

Background: Blending collaborative learning and project-based learning (PBL) based on Wolff (2003) design categories, students interacted in a learning environment where they developed their technology integration practices as well as their technological and collaborative skills.

Purpose: The study aims to understand how seventh grade students perceive a collaborative web-based science project in light of Wolff’s design categories. The goal of the project is to develop their technological and collaborative skills, to educate them about technology integration practices, and to provide an optimum collaborative, PBL experience.

Sample: Seventh grade students aged 12–14 (n = 15) were selected from a rural K–12 school in Turkey through purposeful sampling.

Design and methods: The current study applied proactive action research since it focused on utilizing a new way to enhance students’ technological and collaborative skills and to demonstrate technology integration into science coursework. Data were collected qualitatively through interviews, observation forms, forum archives, and website evaluation rubrics.

Results: The results found virtual spaces such as online tutorials, forums, and collaborative and communicative tools to be beneficial for collaborative PBL. The study supported Wolff’s design features for a collaborative PBL environment, applying features appropriate for a rural K–12 school setting and creating a digitally-enriched environment. As the forum could not be used as effectively as expected because of school limitations, more flexible spaces independent of time and space were needed.

Conclusions: This study’s interdisciplinary, collaborative PBL was efficient in enhancing students’ advanced technological and collaborative skills, as well as exposing them to practices for integrating technology into science. The study applied design features for a collaborative PBL environment with certain revisions.

A case study: Problem-based learning for civil engineering students in transportation courses

This paper describes two case studies where problem-based learning (PBL) has been introduced to undergraduate civil engineering students in University College Dublin. PBL has recently been put in place in the penultimate and final year transport engineering classes in the civil engineering degree in University College Dublin. In this case study, the paper describes how PBL was introduced, the impacts of its introduction and the feedback received by students regarding PBL. PBL was introduced in these years to help students to become deep and active learners and to help them in the transition from passive note taker to researcher and lifelong learner.     

Application of experiential learning to improve student engagement and experience in a mechanical engineering course

ABSTRACT

This paper introduced how a mechanical engineering course was redesigned by applying experiential learning theory to improve student engagement and learning experience. Design of machine elements has been considered by students to be a difficult course. Traditional teaching methods tend not to be effective in engaging students. Experiential learning is a philosophy of learning by doing. In applying an experiential learning approach to the course, the design project and workshop activities were restructured in such a way that students were engaged in direct experience and focused reflection to construct knowledge. By exploring a physical gearbox model, working on subtasks for the design project, having group discussions, raising questions, getting feedback, and moving forward for next subtasks, students experienced the learning cycles of ‘DO, OBSERVE, THINK, and PLAN’ many times. Course survey results showed that application of experiential learning helped to improve student engagement and learning experience significantly.     

The effect of authentic project-based learning on attitudes and career aspirations in STEM

Can engaging college students in client-centered projects in science, technology, engineering, and mathematics (STEM) coursework increase interest in STEM professions? The current study explored the effectiveness of project-based learning (PjBL) courses on student attitudes, major choice, and career aspirations in STEM. Framed in expectancy-value and social cognitive career choice models, we examined the effect of engaging in at least one authentic, project-based course during the first four semesters of college on student STEM attitudes and career aspirations in a quasi-experimental study with a sample of (N = 492) natural science and engineering students. STEM self-efficacy and subjective task value variables (STEM attainment, intrinsic and utility value of STEM courses, and relative cost associated with engaging in STEM courses) were examined as mediators of the relationship between classroom project-based experiences and STEM career aspirations. Gender and underrepresented minority status were also examined. We found that engaging in at least one project-based course during the first four semesters affected student perceptions of STEM skills, perceptions of the utility value of participating in STEM courses, and STEM career aspirations. Furthermore, we found that the effect of project-based courses on STEM career aspirations was mediated by STEM skills and perceptions of course utility. The effect of PjBL was not moderated by race or gender. We highlight areas of future research and the promise of PjBL for engaging students in STEM professions.     

Learning by teaching: undergraduate engineering students improving a community's response capability to an early warning system

This paper reports on a project in which students designed, constructed and tested a model of an existing early warning system with simulation of debris flow in a context of a landslide. Students also assessed rural community members’ knowledge of this system and subsequently taught them to estimate the time needed for evacuation of the community in the event of a landslide. Participants were four undergraduate students in a civil engineering programme at a university in Thailand, as well as nine community members and three external evaluators. Results illustrate project and problem-based, experiential learning and highlight the real-world applications and development of knowledge and of hard and soft skills. The discussion raises issues of scalability and feasibility for implementation of these types of projects in large undergraduate engineering classes.     

Peer assessment in a project-based engineering course: comparing between on-campus and online learning environments

As the number of participants in online distance learning courses increases, peer assessment is becoming a popular strategy for evaluating open assignments and for breaking the social isolation surrounding distance education. Yet, the quality and characteristics of peer assessment in massive online courses has received little attention. Hence, this study was set to examine peer feedback quality and grading accuracy in a project-based course. The study applied a sequential exploratory mixed methods design. It included 339 participants who studied the same engineering course, but in three different modes: on-campus (n = 77), small private online course (n = 110), and massive open online course (MOOC) (n = 152). Content analysis of feedback comments identified four categories: reinforcement, statement, verification and elaboration, arranged in an ascending scale of cognitive ability. The findings indicated that the MOOC participants provided more feedback comments and volunteered to assess more projects than their counterparts did. However, the on-campus students provided higher quality feedback and their peer grading was better correlated with the grades assigned by the teaching assistants.     

Motivating first-year university students by interdisciplinary study projects

ABSTRACT

In order to increase student commitment from the beginning of students’ university careers, the Technische Universität Darmstadt has introduced interdisciplinary study projects involving first-year students from the engineering, natural, social and history, economics and/or human sciences departments. The didactic concept includes sophisticated task design, individual responsibility and a differentiated support system. Using a self-determination theory framework, this study examined the effects of the projects based on survey findings from two projects with more than 1000 students. The results showed that the projects were successful in fulfilling students’ basic psychological needs and in promoting students’ academic engagement. Basic psychological needs were found to be significant predictors of academic engagement. These findings suggest that interdisciplinary study projects can potentially contribute to improving higher education as they fulfil students’ basic psychological needs for competence, relatedness and autonomy and enhance students’ academic engagement.     

Towards characterising design-based learning in engineering education: a review of the literature

Design-based learning is a teaching approach akin to problem-based learning but one to which the design of artefacts, systems and solutions in project-based settings is central. Although design-based learning has been employed in the practice of higher engineering education, it has hardly been theorised at this educational level. The aim of this study is to characterise design-based learning from existing empirical research literature on engineering education. Drawing on a perspective that accounts for domain-specific, idiosyncratic and learner-centred aspects of design problems in the context of engineering education, 50 empirical studies on project-based and problem-based engineering education, to which the design of artefacts is central, were reviewed. Based on the findings, design-based learning is characterised with regard to domain-specificity, learner expertise and task authenticity. The implications of this study for the practice of engineering education are discussed.
