Dual Coding Theory
Dual coding theory emphasizes that people should not ignore the aspect of non-verbal processing of information, and concentrate on verbal processing. Today, many people rely on resources from the web for their learning requirements, and it is imperative to distinguish web sites that can benefit students and those that cannot benefit students (Jairath & Mills, 2005). The assumption of the dual coding theory is that there exist two cognitive systems in the human mind. One system specializes in the processing and representation of nonverbal objects while the other system focuses on language (Jairath & Mills, 2005). This theory has been applied in many fields of learning, which include language, problem solving and concept learning.
According to Clark & Paivio (1991), dual coding theory focuses on mental processes and mental and mental structures. The mental structures are networks that are associative of imaginable and verbal representations. On the other hand, mental processes focus on the activation and development of the mental structures, including the effect of the physical and the social context in learning. Dual coding theory asserts that mental representations relate to distinct nonverbal and verbal properties, and symbolic modes of events of concrete sensorimotor, which form the basis of this theory. Any learning program should consider the verbal system, which contains auditory, visual and verbal codes that are articulate. The development of a web-based program of learning should create a comprehensive approach that captures all the essential aspects of dual coding theory....
the designers of learning programs to develop the nonverbal representation like environmental sounds, actions, visceral or skeletal expressions that symbolize emotions and images that symbolize shape. Designers of learning programs recognize that the principal purpose of learning and education is to acquire knowledge (Clark & Paivio, 1991). Knowledge is transferred to many people through tutorial lessons or private study. Private study has played a significant role in promoting the utilization of web-based research. This has called for improvement of web sources of information so that they can meet the knowledge demands of learners. Dual coding theory proceeds to provide guidelines, which facilitate program designers to ensure that the psychological mechanisms of learning from texts and web pages are designed appropriately (Khan, 2001). Learning program designers follow the avenue that education relevant knowledge is verbally represented in notes and textbooks. Further, nonverbal imaging of information triggers a student’s ease of comprehension of text meaning. The dual coding theory in practice emphasizes that human beings have several systems that process information. Therefore, several channels of communication should be used to convey information in teaching, and in designing learning programs (Jairath & Mills, 2005). The theory informs the designers that the learning of students is influenced in a positive way by presenting illustrations and texts together. Furthermore, animations by computers provide an influential means for presenting learners with visually based information. Learning program designers imitate the idea of dual coding theory since it fosters imagery with mental images that help learners to develop sharp remembering skills. Further, program
