Revolutionize training: Top 10 spaced repetition platforms and their benefits

New Cover Image

Executive Summary: In a world where information overflows, can spaced repetition platforms unlock the door to retaining knowledge for a lifetime? Spaced repetition is a method of helping one develop the skills for recalling information. It is about replaying information at increasingly spaced-out intervals of time. The goal is to help individuals learn, understand, and commit information to long-term memory. Spaced repetition is a highly effective way of learning and retaining information. This article explores how spaced repetition platforms and techniques are improving the field of education and training. This article also highlights the benefits of using spaced repetition platforms, and how they can help organizations improve their L&D. Additionally, this article lists the top 10 spaced repetition platforms which organizations can use to improve their training programs.

Tim woke up to a noisy alarm on a cloudy Wednesday morning. That day, 6:00 AM seemed colder and gloomier than usual. He had been poring over his training course material for nights on end. He sat before masses of pages that described data security and protection, along with details of the newest software his company was using. Yet, after all his work, he wasn’t confident of remembering much. In fact, he was almost sure he did not retain anything he had studied. There was a test that day to assess the successful completion of the training course. Though nervous, Tim dragged himself out of bed. He got dressed and headed to work.

Tim sat quietly at his desk. His teammates crowded the room, buzzing over the reference material. He tried to drown out the sound, but could not tune out the ticking of the clock. Sonia, the L&D specialist in charge of the course, walked into the room at 9:00 AM on the dot. She was empty-handed: no papers, no computer. Tim felt curious. To his delight, Sonia announced the test had been canceled. She also said that the company was going to try out the Spaced Repetition technique, a different method of learning. As she explained this concept, Tim felt like a huge burden was lifted off his shoulders. Sonia mentioned switching to Spaced Repetition platforms and more mobile-driven methods for training. She explained the science behind the technique, and the benefits of using spaced repetition platforms for training corporate teams, just like Tim’s.

Employee stressed over long training courses

A few weeks later, Sonia gathered the team again. Tim was present, looking noticeably happier. The new training techniques had been helpful for him. Sonia began a presentation to show the team how their performance had been since the company began using Spaced Repetition platforms. Almost everyone was completing the course and tests successfully. The team appeared to be well-informed and confident about data security and the new softwares. Tim was certainly enjoying this new method of learning. He didn’t feel intimidated and stressed anymore. The Spaced Repetition technique did wonders to help him remember information for longer periods of time.

Spaced Repetition platforms are certainly an incredible way to make enterprise training more engaging and effective. Let’s understand the concept in more detail.

📣 Message for the reader

People forget nearly 90% of what they have learnt within just 7 days, unless the concepts are reinforced. That’s why employees swamped with documents, presentations, and classroom sessions are not likely to learn much.

However, time constraints make it difficult to reinforce vast concepts.

What can you do instead? Arm your employees with one concept at a time. Studies show the human attention span is only 8.25 seconds, so keep your training concise.

RapL is your software for that.

What are spaced repetition platforms?

As we saw in Tim’s situation, endless hours of cramming are rarely effective for learning. Cramming does not allow for the natural process of memory formation. When masses of information are presented in a short, intense period, the brain is not given enough time to properly process and store the information. This results in the information being stored in short-term memory, rather than in long-term memory. Short-term memory has a limited capacity, and the information is easily forgotten. Cramming also leads to stress and fatigue, which can negatively impact learning and memory.

Spaced Repetition learning technique involves reviewing information multiple times, at increasingly longer intervals. The goal of spaced repetition is to help learners absorb and retain information for longer periods of time. This is ensured by reviewing it at the optimal time for retention. Spaced repetition platforms are digital tools that help users implement this technique. Spaced repetition platforms create personalized study schedules and track progress in real time.

Spaced repetition platforms are based on the concept of spacing effect. This is the observation that people remember things better when they practice spaced repetition instead of cramming. This was first documented by German psychologist Hermann Ebbinghaus in 1885, who conducted experiments on himself to memorize verbal utterances. In one study, he found that he could accurately recite 12-syllable sequences after just one day of cramming. However, he noticed that he could achieve the same results, with just half as many practices spread over three days (Settles and Meeder, 2016).

Spaced repetition platforms utilize the method of spaced repetition to enhance memory retention and aid in learning new information. The concept of spaced repetition involves revisiting learned material at increasing intervals of time. Spaced repetition platforms use this concept by presenting users with questions, tasks or information at increasing intervals, to help them retain information over a longer period.

Employees rejoicing, and enjoying their training

Spaced repetition platforms can be used to learn almost anything, from front-line process knowledge to core product facts and features. They use algorithms that adjust the difficulty level and timing of questions according to how well the user is doing. This ensures they are constantly challenged, but not overwhelmed. With spaced repetition platforms, users can improve their learning skills with ease and efficiency

Let’s look at some benefits of spaced repetition platforms below.

Benefits of spaced repetition platforms

  1. Increases retention: Spaced repetition platforms increase retention by revisiting learned material at increasing intervals of time. These platforms regularly present users with questions or tasks, adjusting the difficulty and timing based on their performance. This method helps strengthen memory retention, making it easier to recall information over a longer period of time.

  2. Makes learning time-efficient: The Spaced Repetition approach ensures users spend their time reviewing information they have forgotten, rather than going over already known material. With this approach, employees can learn effectively in a shorter time frame. They can also ensure that the information is retained in their long-term memory. As a result, employees can save a lot of time and effort in the long run.

  3. Increases employee motivation: Spaced repetition platforms can increase motivation in employees by making the learning process more interactive and engaging. The real-time tracking and analytics store data of the employee’s performance. This approach provides employees with a sense of achievement, as they can see their progress over time. Additionally, spaced repetition platforms can be customized to fit the specific learning needs of employees. This makes the learning process more relevant and interesting to them. This can help increase employee engagement and motivation to learn and improve their skills.

  4. Enables quick and easy reviews: Spaced repetition platforms allow users to quickly review material they have already learned, and are more likely to have forgotten, in a short amount of time. Additionally, spaced repetition platforms can be accessed on various devices. This makes it easy to review material at any time and place, which can make it more convenient for users.

  5. Makes learning engaging: Spaced repetition platforms make learning more engaging. Spaced repetition platforms utilize interactive multimedia elements such as images, videos, audio, animations, games, and quizzes. These supplement traditional text-based learning. This approach makes the learning process more interactive and fun, increasing employee engagement and motivation to learn.

RapL’s innovative approach to learning has proven to significantly increase employee knowledge by 30% in just four weeks. This is with a minimal time commitment of only three to four minutes per day. RapL’s platform employs a unique flipped learning model. This is where questions are presented before answers and explanations. This allows the employee to be tested on their knowledge and confidence first, and receive rationales for their answers later. This approach effectively identifies and instantly corrects individual knowledge gaps.

RapL’s microlearning solution is powered by an AI-driven spaced repetition model. It assesses where an employee is struggling, and provides continuous practice on specific areas. Certain scenarios may be repeated till the user gains mastery in such specific cases. For instance, Logan  is having trouble with a specific scenario about engaging with angry customers in a customer service call. The RapL platform will repeatedly present that scenario until Logan can answer it correctly and with high confidence. This approach ensures high retention of knowledge. It also improves employee confidence in their learning, and increases motivation to continue developing their skills.
