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.

Problem-based learning in formal and informal learning environments

Problem-based learning (PBL) is a student-centered instructional strategy in which students solve problems and reflect on their experiences. Different domains need different approaches in the design of PBL systems. Therefore, we present one case study in this article: A Java Programming PBL. The application is developed as an additional module for the Learning Management System (LMS). This way the LMS is extended by PBL functionality and the LMS learning resources can be used in PBL.     

The use of Facebook to build a community for distance learning students: a case study from the Open University

Social media platforms such as Facebook are commonplace throughout society. However, within higher education institutions such networking environments are still in the developmental stage. This paper describes and discusses case study data from the Open University’s Faculty of Social Science Facebook page. It starts by giving an overview of the literature surrounding social media in higher education before examining how the Social Sciences Faculty at the Open University has used Facebook to help build an academic community. Data includes numerical information on number of likes, demographic data on students who use the page, analysis on the type and nature of comments and more qualitative extracts from postings related to academic questions. It also discusses challenges and difficulties with using such social media tools in a university environment and suggests fruitful areas for future research.     

Enhance low-achieving students' learning involvement in Taiwan's higher education: an approach via e-learning with problem-based learning and self-regulated learning

This study explored the effects of web-enabled pedagogies on students' involvement in learning. A series of quasi-experiments were conducted to investigate whether students' involvement increases over time if intervened, respectively, by problem-based learning (PBL), self-regulated learning (SRL), and their combinations. Two classes of 102 first-year students at a vocational school in a one-semester course were chosen for this empirical study. The results were generally supportive. The authors further discuss the implications for schools, scholars, and teachers engaged in e-learning.     

Relationships among sense of classroom community,perceived cognitive learning and satisfaction of students at an e-learning course

This study aims to determine whether there is a relationship between students' sense of community, perceived cognitive learning, and satisfaction in an e-learning course. Additionally, the relationship of these variables with Internet self-efficacy and final examination scores is investigated. The participants were 88 students enrolled in elementary level English as a Foreign Language course of the distance education program at a higher education institution in Turkey. The results of the study suggest that sense of community and course satisfactions are strongly related to each other. Moreover, students' course satisfaction is highly related to their perceived cognitive learning. Students' perceived cognitive learning was observed to have a very strong relationship with learner-to-content interaction, while learner-to-learner interaction was at medium level and learner-to-instructor interaction was weak.     

Cultivating engineering ethics and critical thinking: a systematic and cross-cultural education approach using problem-based learning

In May 2008, the worst earthquake in more than three decades struck southwest China, killing more than 80,000 people. The complexity of this earthquake makes it an ideal case study to clarify the intertwined issues of ethics in engineering and to help cultivate critical thinking skills. This paper first explores the need to encourage engineering ethics within a cross-cultural context. Next, it presents a systematic model for designing an engineering ethics curriculum based on moral development theory and ethic dilemma analysis. Quantitative and qualitative data from students’ oral and written work were collected and analysed to determine directions for improvement. The paper also presents results of an assessment of this interdisciplinary engineering ethics course. This investigation of a disaster is limited strictly to engineering ethics education; it is not intended to assign blame, but rather to spark debate about ethical issues.

Using an improved virtual learning environment for engineering students

In recent years, e-learning has been used in a chemical engineering subject in the final course of a mining engineering degree, a subject concerned with fuel technology. The low results obtained by students in this subject have led the teacher to search for new strategies to increase grades. Such strategies have consisted of incorporating into the existing virtual environment a dynamics of work with conceptual maps and a consideration of the different learning styles in the classroom. In an attempt to adapt teaching to the individual methods of learning for each student, various activities aimed at strengthening different learning styles have been proposed and concept maps have been used to create meaningful learning experiences. In addition, different modalities of assessment have been proposed, which can be selected by each student according to his or her particular method of learning to avoid penalising one style preference in contrast to another. This combination of e-learning, use of concept maps and catering for different learning styles has involved the implementation of the improved virtual learning environment. This has led to an increase in participation in the subject and has improved student assessment results.     

Problem-based learning used in the context of cardiac rehabilitation: different scenes and different roles

Several studies show that how patients have difficulties in changing lifestyle even though such changes are essential because they are suffering from a life-threatening disease. Coronary artery disease (CAD) patients met 13 times during a year and used problem-based learning (PBL) to improve their empowerment and self-efficacy in making lifestyle changes. District nurses functioned as tutors, helping patients to formulate issues and to state self-care goals. To identify and describe the enactment of PBL, an ethnographic approach was used, including, for example, participant observations and interviews, all derived from six sessions of the education programme. Five different enactments were found, metaphorically expressed as: ‘The study circle’, ‘The classroom’, ‘The expert consultation’, ‘The therapy session’ and ‘The coffee party’. The education programme did not always function as it was supposed to according to the model, but perhaps this should not be seen as a failure of the pedagogical intervention since these enactments as a whole seem to be a way for the patients to be able to make healthy lifestyle changes. The metaphors can broaden the understanding of what can happen when implementing problem-based learning in health care practice.     

A democratic and student-centred approach to facilitating teamwork learning among first-year engineering students: a learning and teaching case study

This work examines an innovative and evolving approach to facilitating teamwork learning in a generic first-year mechanical engineering course. Principles of inclusive, student-active and democratic pedagogy were utilised to engage students on both the social and personal planes. Learner opportunities to facilitate, direct and lead the learning direction were emphasised. This emphasis encouraged a rich learning process and motivated students dismissive of the need to examine their communication skills and those who initially perceived the topic as a personal intrusion. Through a sharing of curriculum decisions, a climate of trust, ownership and shared value arose. Students chose from a range of tools across personality-type indicators, learning style indicators and hierarchies of human needs, to assist their capacity to express and discuss engineering designs and concepts. Peer teaching and collaborative exercises were incorporated to provide an authentic learning context and to further the student's sense of ownership.     

Learning style,sense of community and learning effectiveness in hybrid learning environment

The purpose of this study is to investigate how hybrid learning instruction affects undergraduate students' learning outcome, satisfaction and sense of community. The other aim of the present study is to examine the relationship between students' learning style and learning conditions in mixed online and face-to-face courses. A quasi-experimental design was used and 140 sophomores were recruited in this study. Students' learning outcomes, satisfaction, sense of community and learning styles were measured. Results showed that students in a hybrid course had significantly higher learning scores and satisfaction than did students of the face-to-face courses. The result also indicated that students of hybrid learning classrooms felt a stronger sense of community than did students in a traditional classroom setting. Analysis of learning style indicated that learning style had significant effect on learning outcome in the study group. Accommodator learners had higher e-learning effectiveness than other style learners. Possible reasons of results were discussed.     

Motivation to commit oneself as a determinant of achievement in problem-based learning

Problem-based learning is a constructivist approach toprofessional education stressing the use of real lifeproblems in education. Several previous attempts tounderstand the intricacies of learning in theproblem-based context have led to a causal model,elements of which were tested in the present study.The focus of the investigation was on the students' motivation to committhemselves to studying in a problem-based healthsciences curriculum, expressed in term of levels ofattendance at tutorial meetings. Data were collectedregarding functioning of the tutorial group, tutorfunctioning, level of prior knowledge, quality of theinstructional problems, time spent on individualstudy, academic achievement and increased interest.These data were analyzed using a structural equationsmodeling approach. As hypothesized, commitment appears to bea potent determinant of achievement. In fact, itrepresents one of the strongest determinants oflearning in the model tested.     

To blog or not to blog: Student perceptions of blog effectiveness for learning in a college-level course

Blogs have the potential to increase reflection, sense of community and collaboration in undergraduate classrooms. Studies of their effectiveness are still limited. The purpose of this study was to investigate whether the use of blogs in a large lecture class would enhance students' perceived learning. Students in an undergraduate nutrition course were required to engage in blog conversations over the course of the semester to promote reflective learning. Sixty-seven undergraduates responded to a survey with dimensions on perceived learning and sense of community. Sense of community and computer expertise were identified as significant predictors of perceived learning, when controlled for age, gender, and previous blogging experience. While a majority of the students reported that blogging enhanced their learning and led them to think about course concepts outside the classroom, fewer perceived value in peer comments. Implications for integrating blogging into undergraduate classrooms are discussed.     

Design principles for the blend in blended learning: a collective case study

This paper reports on a collective case study of three blended courses taught by different instructors in a higher education institution, with the purpose of identifying the different types of blend and how the blend supports student learning. Based on the instructors’ and students’ interviews, and document analysis of course outlines, two major principles, consolidation and extension, differentiating the design of the three courses, are identified. The consolidation principle emphasises designing different types of activities for students to think again, so that their knowledge can be consolidated. The extension principle emphasises the extension of the space of learning and catering the diverse needs of students. There are also design principles commonly found, with the emphases on student autonomy, interaction and feedback, and the awareness of student diversity. The findings contribute to the design of blended learning, especially on how the face-to-face and online components can be combined.     

Interacting for learning: Digital portfolios for a learning community in a university course

This study investigates student interactions in a blog-based learning community in a university course. In addition, this study explores the dynamics of group interactions in individual blog-based environments compared with collaborative wiki-based educational activities. A learning community of 56 graduate students wrote individual blogs and weekly group summaries using a wiki environment. The posts were analyzed by identifying a post content type and explicit feedback promotions, and by counting the number of the blogger's own comments and the number of others’ comments per post, received from peers studying in the same versus the other offline group. The results show that choosing the appropriate type of post content (i.e., sharing experiences rather than providing information, explicitly calling for feedback, and providing the blogger's own comments) augments peer interaction in a blog environment, thus explaining 51.4% of variance in peer comments. Group interactions through comments in individual blogs, without the possibility of changing one another's content, seem to be non-intrusive and prompt interactions with offline as well as with online peers. In contrast, actual editing of texts through multi-authored collaborative wikis remained affected by student offline former acquaintance. The results are discussed in terms of social interactions and pedagogical beliefs.     

A guide to establishing hybrid learning courses: Employing information technology to create a new learning experience, and a case study

Hybrid learning, or blended learning, has become an interesting learning delivery method in recent years. Many universities have sought to develop their own hybrid learning courses as another option for students and instructors who prefer to replace some portion of traditional face-to-face meeting time with online instruction. This paper provides some pragmatic guidance for establishing hybrid learning courses in universities. The authors focus on the use of information technology, as well as the development and the design of the course content. The paper also illustrates a case study of hybrid learning courses at NJIT. The research results showed no significant difference between the performance of the students who took a course in hybrid mode versus the performance of those who took the identical course in distance learning mode. Some positive feedback in terms of perceived benefit from the hybrid course instruction and course materials was obtained from the students. The student learning styles were also investigated. The results demonstrated that the majority of students who participated in the hybrid learning course are active/sensing/sequential/visual learners. Most of them preferred visual presentations to verbal explanations. The research results also revealed the difference between learning styles of students with high performance, and those with low performance.     

Community-level environmental projects as learning tools for planners: a case study of graduate planning students

Despite the potential environmental impact of urban planning, there is little research on Environmental Education (EE) in the context of urban planning curricula. This study follows graduate planning students’ learning experience during group projects assigned as part of a planning course at the Technion – Israel Institute of Technology. These participatory projects, characterized as project-based learning and service learning, took place in several communities in Israel. We examined the types of learning impacts the projects engendered by analyzing the reported experiences of the students using parameters from the field of EE. The main goal of this research is to understand the contribution of such practical, hands-on project exercises to the course curriculum for inculcating environmental education themes. Findings indicate that projects helped students acquire and/or improve professional tools. They enhanced motivation to consider environmental concerns in their work and in some cases changed students’ personal environmental behavior.
