INTRODUCTION Industrial revolution in the 19th century brought numerous changes in the lifestyle of the mankind. In the 20th century, numerous innovations and technological advancements in various fields, forms and approaches have affected the day-today life of every human being. As per Ehrmann (1999) the most recent revolution in different spheres has been “made possible by computing, video, and telecommunication.” Fahmy (2004) termed this as “technology revolution.” Field of education has also experienced the effects of these revolutions. Higher and Technical education, like any other segment in our society, is also influenced by technologies and always strives for the necessary changes to use it [1]. There is no denying of the fact that technology in education has maximized the effectiveness of teaching learning process. Many researchers investigating the use of technology in education have found that technology is most powerful when used as a tool for problem-solving, conceptual development, and critical thinking. One of the most powerful uses of technology in education is to tailor instruction to students’ individual learning needs [2]. To make the engineering graduates most suitable to cater to the needs of market, it is necessary to provide them recent technology supported learning environment. One of the ways to provide such a technology supported learning environment is to facilitate their learning through multimedia. In this context it is worth noticing that the use of multimedia has maximized the effectiveness of teaching learning process specifically in terms of student’s outcomes in the form of achievement gains. Researches in ample quantity have proved that multimedia technology influence the quality of teaching-learning because – students play an active role in the learning process and multimedia enriches the learning experience and motivates the students. [3], [4] it provides opportunities for interaction, self pacing & self check. Its features like interactivity through navigational tools and interactive self-assessment questions enable the learner to develop an active relationship with the learning material. Furthermore, interactive multimedia can deliver large amounts of information in ways that make it manageable, approachable, & useful. [2], [5], [6]. d) multimedia saves time by offering realistic work situations in a condensed form, i.e. simulation [4]. e) multimedia has capability to support the learning process with its combined features and facility to control the learning process by the student themselves [4]. f) it facilitates the students to review or revisit material [5]. g) multimedia learning material caters to the needs of lifelong learning, just-in-time training, and retraining of the learners [7]. However, review of studies shows that all multimedia lessons are not equally effective in terms of learning or achievement gains by all the students. Liao (1999) reported that researches over the past two decades have produced inconsistent results about the effects of multimedia on learning [10]. Furthermore, Hammond and Allinson (1989) findings that participants who used multimedia methods gained a lower level of understanding and level of learning even though they felt that they had covered more also have been found to conflict with that of Cognitive Theory of Multimedia Learning and Paivio’s Dual Coding Theory [11]. The above inconsistent result of the research findings are most likely due to the fact that there are multiple factors operating while using multimedia for teaching learning. Hede & Hede, (2002), after a critical analysis of the process of effective learning based on cognitive theories suggested the diagrammatical representation of multimedia effects on learning as shown in Fig. 1 below [12]. Interaction (Functional & Learning) Visual stimulus Attention Verbal stimulus Motivation Cognitive Engagement Intelligence Working Memory Reflection (Processing) Long Term Storage Learning Style Learning Fig.1. Integrated model of multimedia effects on learning The diagram clearly establishes the need of inclusion of various elements such as visual and verbal stimulus to gain & maintain learner’s attention, functional & learning interaction to motivate the learners and to facilitate navigation & learning through multimedia and most important to design the multimedia catering to learning styles of the learners [12]. It appears that while designing multimedia to maximize the learning effectiveness in terms of achievement gains, besides taking care of factors such as visual and verbal stimulus, functional & learning interaction, motivation, and factor such as learning style should also be considered. II. LEARNING STYLE AND MULTIMEDIA DESIGN Many researchers have advocated incorporating learning styles in the multimedia. Stemler (1997) recommended that learner control in multimedia should be designed to accommodate the different abilities and styles of learners [12]. McLaughlin (1999) suggested that to promote improved design of instructional materials, knowledge about individual differences needs to be integrated and connected directly with the design process, so that instructional materials are not only flexible, but also supportive of diversity and capable of accommodating a wide range of learning styles [13]. Hede & Hede (2002) recommended providing multiple views of the same information in multimedia to cater to the different styles of learning, and utilization of variety of media types which permits information to be presented in ways that allow learners to focus on materials that support their particular style of learning [12]. Bajraktarevic, Hall and Fullick (2003) conducted the empirical-analysis of the experimental study relating to the application of learning styles in educational hypermedia and their effects on learning outcomes. The analysis suggested that there was a very strong relationship between matching students’ learning style to the courseware as the findings suggest that all the students achieved significantly higher scores while browsing the session that matched their learning styles. The findings suggest that students benefit from the learning materials being adapted to suit their learning preferences. The results suggest that the learning outcomes can be improved if designers of hypermedia courseware provide a different sequence and presentation of materials to accommodate individual learning style differences [14]. Felder & Brent (2005) suggested that assessing the learning style profile of a class with an instrument such as the Myers-Briggs Type Indicator, the Kolb Learning Style Inventory, or the Index of Learning Styles— without being overly concerned about which students have which preferences—can provide additional support for effective instructional design [15]. Garland & Martin (2005), conducted a study to identify differences between the learning styles of 168 students in traditional face-to-face courses, and students in matched courses taught online, using Kolb Learning Style Inventory. They recommended that when designing online courses the learning style and gender of all students must be considered [16]. Mayer and Moreno (2002) suggested that multimedia presentations should be designed in ways that promote the cognitive processes required for meaningful learning, namely selecting, organizing, and integrating as per cognitive theory of multimedia learning [9]. From the above studies it appears that there is need to include learning styles of the learner in the designing of multimedia packages for effective learning by students of differing learning styles. III. INTEGRATING LEARING STYLES IN DESIGN OF WEB BASED MULTIMEDIA Compared to other media and learning material like handouts, text books, video programmes, etc., multimedia has got unique design elements wherein learning style of the learner can be easily integrated/ accommodated. Various reviews of studies (as shown above) have come out with the idea of integrating learning style at the design stage of the multimedia development. Some of the views suggested by these researchers are1. integrating learning style at the time of accessing the content of the multimedia with learner control [12]. 2. making provision of multiple views (Sequential, global, verbal & visual) of the same information [12]. 3. presentation of learning material in different ways that allows learners to focus on material that support their particular learning style [12]. 4. providing flexibility in accessing of content as per the learning styles of the learner [13]. 5. different sequences and presentation of material to accommodate learning styles [14]. Keeping the above in mind, a web based multimedia package was designed and developed by the present authors and an experimental study was conducted to see its effectiveness in terms of achievement gain by learners with different learning styles. IV. DESIGN AND DEVELOPMENT OF WEB BASED MULTIMEDIA For design and development of present multimedia a content of Induction Motor from Electrical engineering subject of engineering discipline was taken into consideration. The topic was selected/ identified based on various considerations of different elements of multimedia and the enigmatic nature of the topic for students studying in the electrical engineering subject in various engineering disciplines in India. The systems approach model or as popularly known as ADDIE model (Analysis, Design, Development, Implement, and Evaluate) is the mostly used model for instructional design (Fig.2). The individual steps in this model are to assess and analyze needs, Design instruction and presentations, Develop materials, Implement activities and courses, and Evaluate participant progress and instructional materials effectiveness [18]. The design and development of the present web based multimedia is based on the ADDIE model of instructional design as suggested by Reeves (1994) [19][21]. Analyze Implement Evaluate Design Develop Figure 2 ADDIE Model used for multimedia design Considering the implementation of the multimedia on engineering students, Felder and Silverman (1993) Index of learning styles (four learning styles viz. sequential/ global and verbal/ visual out of eight learning styles on four scales) have been used to integrate/ identify learning styles of the engineering students. The Felder & Silverman Index of learning style was employed as this index was basically developed for and also suited for engineering students. The author of the present paper was also prompted to employ these learning styles as some of the review of studies related to multimedia design reveal that linear and branching design of multimedia are more in tune with some of the types of learning styles defined by Felder and Silverman [15]. To cater the learning needs of sequential learners, a sequential navigational path have been provided for accessing multimedia. For global learners combinations of branching and hierarchical paths have been incorporated. To fulfill the learning needs of verbal and visual learners’ content information has been provided in text form and to complement the text contents visuals in the form of photographs, two dimensional graphics, enlarged view of each visual, 2D animations and video clips have been used in the multimedia. A model of integration of learning styles in web based multimedia design and development is given in Fig.3. Web based multimedia on Selected Topic Registration Pre-Test Functional Interactivity Menu Driven Multimedia Access Verbal Learning Style Information in Text Form Visual Learning Style Graphics, Animation & Video clips with narration Contents of Multimedia Post-Test Data Base Learning Interactivity Linear pathway Branching pathways Sequential Learning Style Global Learning Style Feedback Figure 3 Integrating Learning style in Web Based multimedia design Based on the above model a web based multimedia package was developed. Fig. 4 on next page shows the procedure adopted for analysis, design, development & evaluation of Multimedia on Induction Motor in the subject of electrical engineering. The web based multimedia package so designed and developed was field tested on a sample of engineering students in different engineering institutes in India using experimental and control group design. Based on the sequence of the content material accessed by the students while working on the above web based multimedia, the learning styles of the students were identified. The findings of the study show that learning style plays an important role in learning. The students with differing learning styles when accessed the sequence of the content according to their own learning styles perform better in terms of learning. This shows the need of integrating learning style in the web based multimedia design. V. CONCLUSION There are various instructional design methods, model proposed by different researchers, which could be used for design and development of web based multimedia packages. But these models may or may not cater to the individual learning needs of the user or learner. In the present paper a specific model of integrating learning style in web based multimedia design is suggested. However there could be other model also to integrate learning styles in multimedia design. Experts from different fields such as multimedia, instructional design and cognitive psychology should sit together and come out with some more better and viable solution. What is required are to develop more such models to integrate learning styles in multimedia design so that the potential of web based multimedia could be harnessed at its full. There is a high scope for development of web based multimedia on engineering as well as science topics and making them available to the students to foster the learning. First year Engg.
