Problem Based Learning (PBL) implemented into traditional teaching methods. The study indicates that PBL may be an effective complementary method for manufacturing processes. Students need opportunities to practice the newly acquired skills. Before class, rather than beginning with a single question that is multilayered and complex, use a sequence of questions to build knowledge. The paper elaborates approaches to daily products selection and unites to acquire knowledge, self- studying, group discussion and presentation. Class discussion provides an appropriate opportunity to give knowledge in depth. The possibility of offering the students and the efficiency of PBL were also evaluated and discussed. Keywords: Problem based learning; PBL; Manufacturing Processes; Industrial Engineering. 1 Introduction It has been many years for Thai education to support project-based learning (PBL) to succeed their education goals. PBL offers the different educational strategies that are not same as the traditional lecture. Barrows and Tamblyn (1980) published their study on abilities of medical students after trials with new learning and teaching styles. The PBL enhance learning by activate students to work in teams and solve problems together, while developing contents knowledge, idea, reasoning, and interpersonal skills (Jones et al., 2013). Moreover, the involvement with problem-solving also helps to keep students interest in course contents, that they are learning skills needed to be successful in the field (White, 2001; Hmelo-Silver, 2004; Dahms and Stentoft, 2008). Since its emergence within the engineering education, a growing interest in using PBL has been noticed, which is aligned with current efforts to move from decontextualized presentation of technical content to holistic integration of content and practice (Sheppard et al., 2008). Despite an increasing number of literature evidence, a limited number of researchers has provided systematic studies of PBL(Galand et al., 2012) Manufacturing Processes course is an undergraduate course designed to provide the basic skills and knowledge in the areas of manufacturing processes & materials and is part of the core mechanical engineering curriculum (Zhou & Donaldson,2010). Unlike other math-based engineering courses. Consequently, the students may not be able to see the connection and may lose interest in learning the subject {Manu}. So, PBL has a correspondence to gain experience from learning by themselves (Dewey, 1938). Thammasat School of Engineering (TSE) is a young engineering program in its 2nd year. The manufacturing process is being taught for Industrial Engineering and Mechanical Engineering course. A field trip has been included for this course. For practical, students and teacher are able to bridge the gap between what’s been taught in the classroom and what’s been practiced on the manufacturing floor. 1.1 Manufacturing Processes Course Learning and understanding Manufacturing Processes aids our understanding of the world and all around us. Manufacturing Processes phenomena can be described at multiple levels of representation which are interconnected and related in terms of information. There are three levels of Manufacturing Processes representations, namely the Create for example casting, modify (machining, forming) and assembly (Welding, fitting) (Mikell P. Groover,2010). This course provides the student with an introduction to industrial manufacturing from the viewpoint of mechanical technology. Successful completion of the course will provide the student with the benefits, limitations, and applications of different machine tools and engineering materials
