In particular, ubiquitous learning environments based on wireless technologies made the learners able to access the various contents on the Web, search the electronic databases, and interactively communicate with instructors and other learners without time and place constrains (Chang & Sheu, 2002). The purpose of this study is to discuss characteristics of ubiquitous learning and offer an alternative instructional design model based on the ADDIE model which is a systematic instructional design model consisting of five phases: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. Keywords: Instructional design, ubiquitous learning, wireless technology. INTRODUCTION As a new form of electronic learning (e-learning), ubiquitous learning has gained a great popularity. The term “ubiquitous” is defined as “being or seeming to be everywhere at the same time” (The Free Dictionary, 2008). The learners in ubiquitous learning environments are able to access the various contents on the Web, search the electronic databases, interactively communicate with instructors and other learners and obtain knowledge anytime and anywhere through wireless technologies (Chang & Sheu, 2002). According to Yang (2006), the main purpose of ubiquitous learning is to provide intuitive ways for identifying learning collaborators, learning contents and learning services in the right place at the right time. Laroussi (2004) states that ubiquitous learning is leaded by ubiquitous computing. In addition, various technological devices (e.g., personal digital devices such as electronic whiteboard, palm pilot, digital cameras, rocket e-book, mobile phones, personal digital assistants, etc.) besides mobile computers or laptops can be used to provide information to learners wherever and whenever they need it (Laroussi, 2004). Based on the related literature (Ogata, Yin, Yano, 2004) Bomsdorf (2005) discuses the characteristics of ubiquitous learning as the following: Permanency: The students’ works in an ubiquitous learning environment can not be lost and they can be kept permanently. Besides, all the learning processes can be recorded continuously. Accessibility: The students may access to their documents, electronic databases, or videos from anywhere through wireless devices. The information can be also provided based on their requests. Immediacy: The students can get or access any digital information immediately wherever they are. 333 Thus, they can overcome the problems quickly. Besides, the students may record the information or the questions look them later. Interactivity: The students may interact with instructors, peers and experts in through synchronous or asynchronous communication tools. Therefore, the information from various sources is more available. Situating of instructional activities: The learning activities in a ubiquitous learning environment can be embedded in the students’ daily life. The problems encountered and knowledge required are presented in their natural and authentic forms. Thus, students become able to notice the features of problem situations that make particular actions relevant. Adaptability: Students are able to get the right information at the right place in the right way (Ogata, Yin, Yano, 2004, cited in Bomsdorf, 2005) By considering these characteristics we can stay that ubiquitous learning is a promising form of e-learning or distance learning. Although there are various instructional design models for distance learning (Willis & Locke, 2004), the number of instructional design models specifically for ubiquitous learning is insufficient. The purpose of this study is to offer an instructional design model for ubiquitous learning by considering the ADDIE instructional design model, refined by Dick and Carey (1996), and four hierarchy levels of services in ubiquitous learning which were adapted by Laroussi (2004). INSTRUCTIONAL DESIGN AND ADDIE MODEL The term instructional design is defined in Wikipedia (2008) as “the practice of arranging media, communication technology and content to help learners and teachers transfer knowledge most effectively” (http://en.wikipedia.org). The ADDIE model consists of five phases which are: Analysis, design, development, implementation, and evaluation (Learning Theories Knowledgebase, 2007). In addition, Laroussi (2004) adapts four levels of hierarchy for community-oriented services of Amoretti et al. (2003) into hierarchy levels of services in ubiquitous learning which consists of four layers: (1) infrastructures for connectivity and distributed environments, (2) Web-based services, (3) coordination, and (4) pedagogical scenario for mobile learning. In this study, these four layers in ubiquitous learning and the ADDIE model are blended to offer an alternative instructional design model specifically for ubiquitous learning environments (see Figure 1). 1. Analysis: In this phase, various variables such as learning problem, instructional objectives, learners’ needs, existing knowledge, learning environment, delivery options, and the timeline for the course are analyzed and identified (Learning Theories Knowledgebase, 2007). In addition, technological infrastructures (e.g., physical devices, network bandwidth, etc.) for connectivity and distribution and webbased services in ubiquitous learning environment are analyzed and identified in this phase (Laroussi, 2004). 2. Design: In this phase, learning objectives are specified and other issues such as graphic design, user-interface and content are determined (Learning Theories Knowledgebase, 2007). 3. Development: In this phase, the actual content and teaching-learning materials are produced or developed (Learning Theories Knowledgebase, 2007). The mobile and wireless learning and communication devices are also supplied in this phase. Besides, ubiquitous computing and educational resources are aggregated and coordinated as a single environment (Laroussi, 2004). Furthermore, a pedagogical scenario for mobile learning can be developed in this phase. 4. Implementation: In this phase, the plan or scenario, which is designed and developed in prior phases is implemented. The training materials are distributed to the learners through ubiquitous computing or wireless devices (Learning Theories Knowledgebase, 2007). 5. Evaluation: After implementation and delivery, the effectiveness of the training materials is evaluated. Evaluation phase consists of formative and summative evaluation. Formative evaluation is conducted in every stage of the instructional design model. Summative evaluation, which focuses is on the outcome (Bhola, 1990), contains tests designed for criterion-related referenced items and provides opportunities for feedback from the users or learners (Learning Theories Knowledgebase, 2007; Yalın, 2004). Analysis Instructional objectives, Learners’ needs, Existing knowledge, Learning environment, Timeline for the course, Infrastructure for wireless technology and delivery options. Design Specification of learning objectives. Determination of graphic design, user-interface and content. Development Production of the actual content. Development of teaching-learning materials.

Formative evaluation is conducted in every stage. Figure 1. An instructional design model based on the ADDIE model (Learning Theories Knowledgebase, 2007) and hierarchy levels of services in ubiquitous learning (Laroussi, 2004). 334 Pedagogical Scenario For Ubiquitous Learning The below pedagogical scenario for ubiquitous learning (see Figure 2) developed by Laroussi (2004) shows that students can be inside or outside of the learning environment. Besides, they are equipped with a computer or with any mobile device. Thus, they can interact and have a dialogue with their classmates, professor or another professor. Figure 2. Scenario of interaction in Ubiquitous Learning (Laroussi, 2004) In addition, Chang and Sheu, (2002) designed a project to develop advanced wireless technologies for building an Ad Hoc classroom in order to create a modern and new learning environment. Hence, they developed software systems, including Ad Hoc classroom system and electronic school bag (eSchoolbag) systems, on both PC server and mobile devices such as PDA and Notebook which are carried by students and the teacher (see Figure 3). establishes a self-motivated learning environment for students. Therefore, in this system several teaching-learning activities and teaching-learning models can be executed outdoor and teacher and students can interact without time and place limitations when it is needed (Chang and Sheu, 2002). CONCLUSION As previously discussed, ubiquitous learning provides intuitive ways for identifying learning collaborators, learning contents and learning services in the right place at the right time (Yang, 2006). The characteristics of ubiquitous learning can be listed as permanency accessibility, immediacy, interactivity, situating of instructional activities and adaptability (Ogata, Yin, Yano, 2004, cited in Bomsdorf, 2005). These characteristics suggest that ubiquitous learning is an applicable and promising form of e-learning. However, the number of instructional design model specifically for ubiquitous learning is insufficient. This study offers an instructional design model for ubiquitous learning by considering the ADDIE model., refined by Dick and Carey (1996). Similar to the ADDIE model, the instructional design model offered in this study consists of phases: (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. However, these five phases are blended with four hierarchy levels of services in ubiquitous learning developed by Laroussi (2004) to make it specific to the ubiquitous learning environments. Finally, we think that the instructional design model offered in this study will be an applicable model to achieve objectives and to meet the needs of learners in an ubiquitous learning environment.
