The shift from lecture-based education to problem-based education represents a shift from teacher-centred learning to autonomous learning. This qualitative study will therefore focus on student responses to this shift in emphasis. In the first year of the curriculum change, this research will capture and theorize about student approaches to learning in the PBL curriculum and outcomes as this area has received little attention in engineering PBL curriculum research. This research study will use four types of data collection methods. They are observation, interview, document review and audio-visual material. Apart from this, there will be a group-problem solving task designed by the researcher. First year electrical engineering students and their teachers at an Australian university are being observed. Student participants are also being interviewed. In this paper the aims of the study, the research design and the methodology used will be presented. Some initial findings from the first round of interviews will also be presented.

The focus of this study was to identify and explore students’ application of generic skills, cross-disciplinary knowledge and skills, innovative thinking and engineering disciplinary knowledge. While this was the main aim of this study, we also used the findings of this study to triangulate the findings of a broader study which aims to identify and explore students’ perceptions of problem based learning (PBL) in first year electrical engineering. The broader qualitative study of learners in a problem based engineering context will identify, explore and report on the factors that influence student learning behaviours and their attitudes as future engineers. Studying the learning cultures from the students’ view point in a diverse student group should provide evidence to further theorize about the models of self-regulation in autonomous learners. For this group problem solving activity, we designed a problem (advanced lift controller system) and allowed students one hour to work on a solution for this problem. The eight students from a number of actual PBL groups were divided into two groups depending upon their availability. Both groups were given the same problem. The researcher played the role of a facilitator and collected the data simultaneously. Students were given access to books relevant to the problem, computer access and access to the Internet. They were also provided with links to sample websites such as the University’s electronic library and other technology related websites on the World Wide Web. The activity was designed such that students were not required to arrive at a definite outcome. However, they were asked to brainstorm ideas, and as a group, to decide on ways that they would obtain and share information and to formulate and suggest possible innovative solutions to the problem. Data for this activity was collected by means of observation. The activity was audio and video recorded in order to help revisit the data at any stage. At the time this study was conducted, students had completed two PBL units in their first year of an electronic and electrical engineering undergraduate degree course. This study also provided insight into students’ attitudes and their behaviours towards learning in a group setting, learning approaches and outcomes, different responses to the heterogeneity of the students in the group, and their responsibility and accountability in an autonomous learning setting such as PBL.

Prior studies have offered insight into the methods, application, and experiences of teaching using PBL. However, student behaviours and the learning cultures that develop in PBL settings are also important. In this paper, we present the ways students of a first year engineering course at an Australian university approach PBL. A number of PBL teams in the same subject were observed throughout two semesters with their consent. This paper reports on two of these teams. Some observations were video taped to aid analysis. The purpose of this study was to analyse and compare learning approaches that help or hinder successful group outcomes. It is evident from the data that individuals in the groups have a strong influence on what is learnt. Some students also focus more on exploiting the assessment system than on maximising their learning.

The PBL approach claims to build extended technological and social understandings as it offers a context for development of autonomous learners. It has an emphasis on collective and individual learning motivation and decision-making behaviours. In this paper, we present the responses of students to the heterogeneous characteristic of PBL teams in a first year electrical engineering degree course at an Australian University. The learning cultures in PBL teams that emerge as a result of the diverse characteristics of teams are also presented in this paper. A number of PBL teams were observed and interviewed throughout their first year course with their consent. Analysis of the data collected about students’ learning and outcomes in PBL teams informed the ways in which individual students approach their learning, the ways in which they control, regulate and direct their learning individually and as a group and the extent to which they participate, engage and thereby learn in the course. It is evident that some students have a strong influence on the behaviour of other students in their team. These students also influenced what is learnt as a team, the ways in which they interrelated, worked as a team and problem solved in changing circumstances. Therefore, when designing student teams for PBL academics should not assume that a mono-cultural group or a mixed-ability group of students will work successfully together. We think that the results of this research inform both the design of PBL courses and the facilitation of PBL groups to accomplish successful group learning outcomes.

Fifty students in eight PBL teams in a first year undergraduate engineering course participated in this study. Data collection for the study involved ethnographic observations supplemented by individual and focus group interviews and analysis of student work samples. It was found that most of the first year electrical engineering students acquired disciplinary knowledge relevant to the particular tasks that they worked on for the team. However, it appeared that they either did not appreciate the connection of their task to the main problem or did not value linking their task with the tasks of other members in their team. We think the findings of this paper should inform the design of PBL courses, in particular the design of problems and assessment. If we want students to cross disciplinary boundaries, we need to incorporate strategies that require them to integrate knowledge across disciplinary boundaries while solving problems.

The analysis of teachers’ reflections on their learning explored teachers’ understanding of mathematical connections and their appreciation of mathematical structure. The findings indicate that a professional learning program about senior secondary mathematics can enable practicing teachers to deepen and broaden their knowledge for teaching junior secondary mathematics and develop their practice to support their students’ present and future learning of mathematics. Further research is needed about professional learning approaches and tasks that may enable teachers to imbed and develop awareness of structure in their practice.

Ethnographic approaches were used for data collection and analysis. This study found that student learning in a PBL team in this setting was mainly influenced by the attitudes, behaviour and learning approaches of the student members in that team. Three different learning cultures that emerged from the analysis of eight PBL teams are reported here. They are the finishing culture, the performing culture and the collaborative learning culture. It was found that the team that used a collaborative approach to learning benefited the most in this PBL setting. Students in this team approached learning at a deep level. The findings of this study imply that students in a problem-based, or project-based, learning setting may not automatically adopt a collaborative learning culture. Hence, it is important for institutions and teachers to identify and consider the factors that influence student learning in their particular setting, provide students with necessary tools and ongoing coaching to nurture deep learning approaches in PBL teams.
