Problem based and project based learning (PBL), also called real life problem based learning, is a well establish pedagogical method in different domain of the studies around the world. The students are working in a team and learning themselves by solving subject related problems in this method. PBL history has revealed that at first it has been implemented in the medicine and law education but for the course of time it has spread its application to various fields of education like natural sciences, social sciences and applied sciences etc. (Maria, 2010). A large number of publications have found regarding successful implementation of PBL in engineering education in different countries throughout the world (Du, de Graaff, and7 Kolmos, 2009). Like other domains of engineering education, some examples have also been found in the area of textile engineering education. For instance, in the University of Manchester (Sayer et al., 2006), in the University of Minnesota (Bye, 2011) and, in Illinois State University (Gam and7 Banning, 2011).
In order to highlight the necessity of PBL implementation in engineering education, Mills and Treagust’s (2003, p.2) stated the followings:
In recent years studies have been conducted in many countries to determine the technical and personal abilities required of engineers by today’s industry. These studies have indicated some key concerns. Today’s engineering graduates need to have strong communication and teamwork skills, but they don’t. They need to have a broader perspective of the issues that concern their profession such as social, environmental and economic issues, but they haven’t. Finally they are graduating with good knowledge of fundamental engineering science, digital and computer literacy, but they don’t know how to apply that in practice.
PBL is one of the most influential pedagogical methods which can give all possible efforts to facilitate the engineering education by creating institutional profiles, emphasizing students’ learning and motivation, achieving new competences, enhancing the quality of education, decreasing dropout rates, better duration rates, and better collaboration with industry (Kolmos et. al, 2009).
PBL provides an opportunity for students to be self-directed life-long learner which is mandatory for equipping engineering students with the skill and knowledge (Baral et al., 2012). According to de Graaff and Kolmos (2003, p.658):
PBL is a real life problem oriented learning method, which will be solved by conducting a project. Through these activities students will achieve the competences which will be helpful for their professional life.
On the other hand Six Sigma, as a quality management approach, systematical and structured improvement procedures provides teams a methodological framework to guide them in the conduct of improvement projects (Pande et al., 2002).That means the function of both PBL and Six Sigma approaches are quite similar in nature: to solve the problems by executing projects in a systematic way.
In this research, at first PBL has been introduced in the textile engineering education at “Lucian Blaga” University of Sibiu (LBUS) through a collaborative project with a textile factory, where Six Sigma projects have also been executed simultaneously. The PBL team has contributed to the Six Sigma project team to solve the problem in factory premises. Finally, the students’ performance and the contributing effect of PBL activities to Six Sigma project have been assessed by conducting quantitative survey method containing structured questionnaires.
