While developing e-learning courses, the common mistakes that developers make is to include on-screen text, audio narration and graphics simultaneously in the courses. This only overloads learners.
The logic behind using audio in e-learning courses is to split the information into two cognitive channels-words in the auditory channel and pictures in the visual channels. Through visual channels he or she can see the pictures and through auditory channel he or she can listen to the audio so that there is no overload on the learners. According to the Modality principle, graphics are described well, using audio narration instead of on-screen text.
Cognitive overload is where learners must pay attention to audio, on-screen text and graphics in order to understand the underlying concept. By using the Modality principle, learners do not experience cognitive overload as they have to pay attention only to the audio and the on-screen text and visuals.
Now, here are the reasons for the Modality principle. As the visual channel has very limited capacity, it cannot pay attention to the on-screen text and the graphics at the same time as this will overload the learners, whereas if through the visual channel learners can see only graphics and through the auditory channel learners can only listen to the audio narration, there will not be any overload on the learners. Therefore, if both the visual and auditory channels have been properly processed, there will be no any overload in the learning. In a recent research, it was revealed that 40% of the learning is performed through graphics and audio narration and learners perform much better when graphics were described using narration rather than on-screen text.
The Modality principle also has some limitations while designing and developing e-learning solutions:
- Sometimes technical demands cannot be met – bandwidth issues, use of sound cards and headphones. There is also difficulty in explaining technical and mathematical formula though audio alone, as we need to show them on screen as well.
- Text needs to remain on screen when:
- Difficult terms are used
- Key steps in the procedure are listed
- Directions are to be given to a practice exercise that must also be present on-screen
Needless to say, the Modality principle maximizes learning and helps learners receive an auditory explanation for on-screen graphics and text.

Scenario based learning is learning from a specific scenario. In this case the learners are given a particular scenario that mirror real time experiences and examples. Scenarios urge learners to make careful decisions in a given situation and as a result, they are prepared for similar situations when on job.
In this blog, I will take you through how the Agile way of e-learning Project Management helped us in streamlining our projects.
In the past years, we have been following the ADDIE model in planning and developing e-learning projects. The success rate of the projects was below 60%.This was an indication of the fact that the remaining 40% of projects were still not closing on time, had higher defects leading to extensive rework, and recorded low customer satisfaction with less ROI to our organization. We found that the main reason for this situation was that customers’ requirements were not properly understood at the initial stage of the project.
Recently, we were working on a course related to crisis management; how to report and whom to report when a crisis (incident) occurs in an organization.
Earlier employees would simply send an email about the incident and be done with it. The objective of this course is to tell learners to use the tool to file incidents and how it should be done.
Do you know who won the first prize in Asia’s got Talent last year? It was a group from Philippines who call themselves El Gamma Penumbra. They are an all-male, shadow play group. Well, I had never heard of them until someone forwarded a video of their performance through WhatsApp. Wow, what a performance! I will share the video in a while and you must see it to believe it! There is a lot we can learn from them as we develop e-learning or online courses.
The job of a pharmaceutical sales representative is quite challenging. Often, they need to convince doctors, who are more knowledgeable about diseases and medicines than themselves, to prescribe their firms’ products. So, it is very important that pharmaceutical companies impart comprehensive training to their sales personnel, to enable them to handle physicians’ queries effectively.
Effective performance management is the mantra to success in today’s highly competitive business environment. A well-designed performance management process involves various steps such as setting goals, spotting performance gaps, coaching, discussing improvements and rewarding personnel for their contribution.
“The most important principle for designing lively e-learning is to see e-learning design not as information design but as designing an experience.” – Cathy Moore
“Oh no!”, “Why do I need to take this online course?” – these are some of the common reactions from learners when they are asked to take courses on dry topics such as regulatory norms. As instructional designers, we are often tasked with creating e-learning courses on subjects that most learners consider boring.
In any eLearning course, we are so caught up with creating content and visuals that we tend to neglect a vital aspect of any eLearning course, which is the Graphic User Interface, popularly known as the GUI. It is a well-known fact that the GUI can have a make or break effect on your e-learning course.
A trailer is an advertisement of a new movie; its purpose is to kindle eagerness among people to watch the movie and enjoy the story. The main objective of a trailer is to increase the interest levels within us. On viewing a trailer, we become so enthusiastic and sometimes even restless to know the hidden obscurities and mysteries and the real story, which is yet to come. The same simile can be applied in the case of e-learning too.
The manufacturing industry is one of the most important sectors of the US economy. According to a report released by the Economic Policy Institute, this sector contributed about $2.1 trillion (12.5 percent of total U.S. gross domestic product) in 2013. The report also stated that manufacturing companies employ about 12 million people or 8.8% of the total American workforce. Developments in this industry act as catalysts to the growth of the economy, and training plays a vital role in enhancing the operational efficiency of firms in this sector.
