The biggest challenge for any learning program is to ensure retention of learning. If learners do not retain what they learned in the program, the program is not very useful.
Foster Knowledge Retention with Spaced Learning
For a long time, educationists researched methods to increase the retention of learning to maximize learning outcomes. One of the key findings of these researchers is known as the spacing effect. A German psychologist and researcher in quantitative memory, Hermann Ebbinghaus, was the first to demonstrate the spacing effect. According to him, one can maximize learning retention by repeating instructions at regular intervals. Educationists today call it the spacing effect, as instructions are given to learners at regular intervals.
How Is Spaced Learning Designed?
Let’s find out how one can design a spaced learning program. With spaced learning, the learning material is divided into smaller modules. Learners take the modules at a certain point in time.
Learners then retake the modules after a period of time has passed, say one week. Then learners take the modules again, but this time after a longer interval, maybe two weeks. Learners then take the modules once more after a defined time, perhaps three weeks.
This is repeated until learners attain mastery of the concept. The number of repetitions and the spacing between repetitions is determined by learning designers based on various factors, such as complexity, learner profile, mastery level required, etc.
Why Is Spaced Learning Effective?
To understand why spaced learning is effective in ensuring retention, we need to understand how human memory works. Whatever we learn gets stored in the short-term working memory. The information learned is retained only when it is transferred to long-term memory.
However, unlike computer memory, human memory is not permanent. As human beings, we tend to forget things we haven’t recalled for a long time. This loss of knowledge is known as the forgetting curve.
The forgetting curve is nothing but how much we forget over time when our brain does not repeat the same activity. For example, let’s say someone learns five words of a new language today. If the person does not use the words in any way for the next two weeks, they will be able to remember only two out of five words. Spaced learning takes into account this forgetting curve and repeats the learning module before learners completely forget the information. This reinforcement makes the brain work hard to remember what was learned during the first instance. The more the brain repeats this, the better retention becomes.
In this way, the memory is also transferred to long-term memory. As learners keep repeating the process, the brain gets more and more efficient in remembering what was learned. In layman’s terms, we call this “practice makes perfect.”
How to Incorporate Spaced Learning Design in eLearning Design
Spaced learning design is essentially a content design and delivery strategy that takes into account the spaced learning concept. Here are some of the essentials of spaced eLearning design:
- Short and frequent modules – Plan multiple shorter modules instead of a single longer module.
- Frequent review modules – Create review modules to be taken by learners at defined but extended intervals; assess the retention and progress of learners.
- All new modules start with a recap of older modules.
- Relate new concepts to older concepts.
- Create a summary and checklist as reinforcements.
Advantages of eLearning in Designing and Delivering Spaced Learning
Every individual has a different forgetting curve. Thus, consider personalizing the frequency of instruction to meet the optimum speed and learning requirements of each individual. Since eLearning modules are self-paced and can be delivered anytime through learning management systems, individual needs can be catered to effectively. This is not possible in traditional classroom-based delivery.
Challenges and Drawbacks
Spaced learning requires a long-term and dedicated commitment toward a learning program. Some learners may find it hard to commit to a longer duration for learning something. Moreover, there are situations when learners need to apply their learning within a short period. Spaced learning design can be supplemented with other learning design strategies in such scenarios.
Most importantly, spaced learning design demands deep knowledge and skill from learning designers to define the effective frequency and load. If the frequency is too high or too low, learning will be rendered ineffective.
Conclusion
Spaced learning design is one of the best learning design methodologies to maximize the retention of knowledge. If designed correctly, it can ensure long-term learning and mastery of concepts.
