Multimedia in Education

 

 

The turf of multimedia covers a wide range of technologies that aim to develop solutions for learning and delivering knowledge. " ... multimedia can be defined as integration of multiple media elements (audio, video, graphics, text, animation, etc.) into one the synergetic and symbiotic whole that results in more benefits for the end-user than any one of the media elements can provide individually" (Reddi, 2003). By this definition of multimedia, Reddi emphasizes that multimedia with all of its elements are more effective than any one component. Education encounters, in modern times, challenges in all aspects of social, economic & cultural life; the most important of which is over-population, over-knowledge, education philosophy development & the change of teacher's role, the spread of illiteracy, lack of the staff & the technological development & mass media (Aloraini, 2005, p. 30–32). This drove the teaching staff to use modern teaching technologies to face some of the main problems which education & its productivity encounter, by increasing the learning level, which may be achieved by providing equal opportunities for all people whenever & wherever they are while taking into account for the individual differences between learners (Wilkinson, 1986, p. 13). To improve educational productivity, some teaching staff sought mainstream technology within education, developing traditional techniques & using new educational methods (Al-A'ny, 2000).

Educational media refers to channels of communication that carry messages with an instructional purpose. They are usually utilized for the sole purpose of learning and teaching (Mukherjee, 2018). Educational multimedia has been found to t draws upon more than one of the five human senses, utilizing the two fundamental senses vital for information reception – sight and sound.

Khan's first take on multimedia:

Artificial Intelligence in Multimedia:

Recent advances in technology, cybernetics, machine learning, and cloud computing recommend the essential development of multimedia & AI technologies. These changes can advance many practices in educational technology. Cloud computing fits well since it provides a flexible stack of computing, storage, and software services at a low cost. As a result, we are witnessing a standard shift toward multimedia cloud computing. The computationally demanding components of multimedia systems, services, and applications are moving onto the cloud. The end user's mobile device is being used as an interface for accessing those services. I would like to see smart devices speak and converse with emotion and expressiveness, enrich videos, and other multimedia components in the learning environment.

Khan would like to see:

Interactive Multimedia:

Mirriam-Webster dictionary (2016) defines interaction as the actions or input of a user, especially: relating to, or being a two-way electronic communication system that involves a user's orders responses. Since multimedia learning is that it takes advantage of the brain's ability to make connections between verbal and visual representations of content, leading to a deeper understanding, which supports the transfer of learning to other situations as well. In the case of interactive multimedia, items or tools would provide the learner with hands-on learning models. He should be able to manipulate to gain understanding and mastery of a concept. These interactions can assist students in advancing from beginner knowledge to a more expert understanding of abstract ideas through visual and kinesthetic senses.  The general objective of the process would be that the learner understands the similarities and differences of the different types of manipulatives media options and information and gain comprehensive knowledge on how to analyze, design, develop, implement (utilize) and evaluate his lesson.

 

My third vision for multimedia applications in education:

Computational Multimedia Simulation:

While in engineering school, I noticed that my female colleagues had problems with fluid dynamics and mechanics of air/fluids flow in gas turbines. Three-dimensional visualization skills are critically important for success in engineering careers. Before a complex problem can be solved, the engineer must visualize how all of the components in the system work and fit together. Unfortunately, studies have shown that the 3-D spatial visualization skills of women engineering students lag significantly behind those of their male counterparts. Fluid mechanics uses numerical analysis and data structures to analyze and solve problems that involve fluid flows in different situations.  The multimedia simulation could be used to perform the calculations required to simulate the free-stream flow of the fluid and the interaction of the fluid (liquids and gases) with surfaces defined by boundary conditions. With high-speed computer simulations, better solutions can be achieved, and are often required to solve the largest and most complex problems.
