The Importance of Revision: Revision and Memory Techniques

ADvTECH Group • May 27, 2022

Don’t leave your revision to the last minute; on-going revision as you learn can take your information recall, and your marks, to a whole new level.

Exams are not a torture practice used by teachers to terrify kids. Exams are simply a tool that helps to test your level of learning and understanding of a subject, and revision helps your brain to load knowledge into your long-term memory so that you can recall important information long after you have finished learning. Don’t leave your revision to the last minute; on-going revision as you learn can take your information recall, and your marks, to a whole new level.


Studies show that you can hold between five to nine facts in your short-term memory. After 30 seconds these facts begin to ‘fall away’ if you don’t commit them to memory – that’s a lot shorter than that Maths exam you have coming up. So, get your learning space organised, leave yourself enough time to revise thoroughly, and find a memory/revision technique that’ll help you to commit information to memory. Here are three great revision tips for you:


1.   A picture really is worth a thousand words


The human brain remembers pictures and experiences much better than it does written words. Fact is, the more senses you involve in your learning, the more involved your brain will be, and the more information you will retain.


So, when you’re starting to draw up revision notes, try to draw diagrams of key facts and ideas to help you memorise them. Simple spider diagrams and mind maps are very helpful when it comes to breaking facts down and remembering answers to complex questions. You could even draw a simple picture to group related facts together in the chunking method. What is the ‘Chunking Method’ you may ask? Read on!

 

2.   The ‘Chunking Method’


Have you ever thought how hard it is to remember your trigonometry theorems, but you can rattle off your bestie’s phone number without even thinking? That’s because when information is ‘chunked’ into smaller bits, like a phone number is typically displayed with gaps between three and four digits, it’s much easier to remember.

 

So, how do you do this with your schoolwork? First, you need to group your revision into sections – similar info gets grouped into smaller chunks. Then you group it into even smaller chunks using bullet point, key words, even key letters. Try to group facts or information into groups of threes, as this will help your brain remember it even better.


 A great example of chunking would be a shopping list – rather than listing everything as one unit, it makes sense to break the items up under dairy, fresh fruit and vegetables, non-perishables, etc. Use different colours or fonts to differentiate the chunks and try tp develop mnemonics to help you here too (a mnemonic would be OIL RIG for chemistry learners, which equates to Oxidation It Loses electrons and Reduction It Gains electrons).

 

3.   Use the Pomodoro Method


Chunking information isn’t the only way to boost your revision, braking up your study TIME boosts your brain too. This technique involves the following: revise for 25 minutes, then take a 5-minute break, and repeat this cycle for 2 hours. The take a 30-minute break and start the 25-5 cycle again for another two hours. Why? Well, after 25 minutes your brain’s ability to retain information decreases, so taking a short break gives it space to reset and take in more information again (rather than just blocking it out).


As you can see, you never have to cram again! Boost your brain power and marks by simply changing your approach to revision and studying, and you’ll be well prepared for those exams!

A Lifelong Educator Mr Chris Herbst has spent 41 years in the classroom. With a Bachelor of Education from the University of the Witwatersrand, he has taught countless learners over the decades. He joined Crawford International Sandton in 1999 and currently teaches Afrikaans to students from Grade 8 to Grade 12. His role spans across five different year groups, a challenge he embraces. “I have my hands full as I navigate the excitement and challenges of teaching an additional language to five different grades,” he says. Why Teaching Still Matters For Mr Herbst, teaching is not a job. It is something he feels deeply connected to. “Teaching is my great passion and calling. The classroom is where I find my motivation and inspiration,” he shares. “When we have a really good lesson and I see our students leave having learned something new, or figured out a challenging concept, then I am motivated and inspired all over again.” These everyday moments keep him grounded in his purpose. They are the quiet victories that reaffirm his place in the classroom. Freedom to Teach with Meaning Mr Herbst values Crawford’s approach to learning, particularly the way it supports teacher agency and student-centred learning. “I love the fact that the focus is student-centred, and that as teachers we have the freedom and the responsibility to create a teaching and learning environment that works best for every learning need,” he says. He believes this flexibility allows for learning to become more meaningful. “If I identify that a particular topic or poem has piqued the interest of my class, I have the freedom to delve deeper and really explore the subject matter without being bound by rigid syllabus rules and time frames.” Connecting Language to the Real World Teaching Afrikaans in a school where it is often an additional language means finding ways to make it resonate. Mr Herbst understands that for many students, the subject may not come naturally. “For many students, learning another language may initially feel like a requirement rather than a passion,” he explains. To bridge that gap, he brings the language to life through content that students can relate to. “It’s important to integrate engaging, real-world content such as music, movies, and stories that align with the students’ interests.” These tools, he believes, help students see the language in context and build an emotional connection to it. A Teaching Legacy  Over the course of his career, Mr Herbst has taught more than one generation in the same family. It is a milestone he reflects on with pride. “I have taught students who are now parents, and I am teaching their children today. It doesn’t get better than that.” But what stands out most for him is being remembered. “By far my biggest kick is when a past student recognises me and comes over to strike up a conversation and talk about their life and work after school.”

ALUMNI SPOTLIGHT: DYLAN BIZJAK Crawford International Sandton From the classrooms of Crawford International Sandton to the forefront of aeronautical engineering in the Netherlands, Dylan Bizjak’s journey is one of ambition, resilience and innovation . Pursuing a Passion for Engineering After matriculating in 2019, Dylan initially pursued Aeronautical Engineering at Wits University. However, six months into his studies, a new opportunity emerged, one that would take him beyond South Africa’s borders. He secured a place at Inholland University of Applied Sciences in Delft, Netherlands, where he embraced the challenge of international study, even navigating his first year remotely due to the pandemic. Now a graduate with a BSc in Aeronautical Engineering (2024), Dylan has stepped into the professional world, joining Eve Reverse, a pioneering start-up dedicated to climate-positive innovation. What began as an internship in his final year evolved into a full-time role as a Research and Development Engineer, where he contributes to the creation of sustainable, carbon-negative materials. His proudest achievement? Playing a key role in the development of the Eve Dry Tile, an innovative flax fibre material designed to reduce emissions and waste in manufacturing. Achievements at Crawford International Sandton Gareth Beach Award (2019) – Recognised for bravery, dedication, self-development and outstanding achievement in swimming. Sportsman of the Year (2019) – Acknowledged for excellence in swimming, basketball and boxing.  Reflections on Crawford Dylan credits his time at Crawford for preparing him for both academic and personal success on the global stage. “Crawford’s approach equips you for university and beyond, whether in South Africa or internationally. It’s not just about academics but about becoming a well-rounded critical thinker and team player. Exposure to diverse cultures, teamwork, individuality and taking responsibility for my outcomes were invaluable lessons I carried with me.” Words of Wisdom To his younger self, Dylan would say: “Step out of your comfort zone sooner. Growth happens when you challenge yourself. Leaving home was tough, but the personal and professional growth was worth every stumble along the way.” Dylan’s story is a testament to courage, hard work and the power of embracing the unknown. From South Africa to the Netherlands, he is proving that the sky isn’t the limit, it is just the beginning.
