Problem-based learning (PBL) is an alternative to traditional lecture learning environment. In order to support teaching fundamentals of framing construction, PBL was used in a course in Missouri S&T. Handson learning experience for longer retention of desired knowledge was the main goal of this case study. Education of framing construction is a component of architectural engineering and variety materials are in use to assembly framing system in construction industry. Scaled model activity is targeted in PBL block and this activity directly dependent on material which is available, affordable and workable by the students. Balsa stick which has these properties is the choice reason of using timber framing system in PBL block. Due to the experiences in the world, it is recommended that using multiple educational models together as preparatory blocks including traditional lecture learning environment and PBL together. PBL block is supported by preparatory blocks such as construction site visits and mock-up assemblies. PBL activity narrowed through "the task project" on framing construction to be completed by the students in limited time. A survey was held in order to determine outcomes of the activities and PBL had positive impact on the traditional lecture learning environment in architectural engineering.

Abstract"Building components design" education is carried out in different names in undergraduate education. The educational model presented herein accepts the building as a set of systems. Used notions of prefabrication, open building concept and prescriptive codes are the determiner for problem-based learning in "building components design" education. Problem-based learning as an alternative to traditional lecture learning environment targets students' retention of desired knowledge. Results from this ongoing research with are discussed in this paper. The aim of this research is to show that PBL is an applicable educational model in "building components design" by using specific methodology. Therefore a series of methodologies and applicable building technologies are being presented herein. Existing notions in building industry are being applied to higher education by defining a formulation. The task in desired learning environment is to complete scaled models of selected building technology. The selection depends on the available and workable material for the students. This formulation is being tested already and proposed herein for other related courses as long as doing necessary revisions. Keywords: Problem-based learning, building components design, open building IntroductionTimber and cold-formed steel framing systems are widespread in construction industry in the world as both stick-built and panelized systems. In addition, reinforced concrete (RC) prefabricated, autoclaved aerated concrete (AAC) panel and structural insulated panel (SIP) systems are the other possible construction methods for panelized system used widely as well. Engineers, architects and other building professionals need basic knowledge of these construction methods. Meeting needs of future engineers and architects, education of construction methods is an essential part of the undergraduate curriculum of architectural engineering. Problem-based learning is incorporated with the thought learning environment to teach "building components design" in higher education beside traditional learning environment. Particularly hands-on learning experience is crucial to improve design skills and longer retention of desired knowledge. Design education of industrialized building systems have been carried out in architectural and civil engineering departments in different names in the world.
