Science and Maths Video Tutorials – Progress


With high school maths and science as the initial focus, hello tutor is an online video tutorial learning platform which harnesses the power of the internet. Through crowdsourcing, we seek to deliver high-quality educational content to learners in a convenient and cost-effective way.  Hello tutor is an education eco-system which through the use of technology brings together tutors and learners effectively and efficiently in a manner beneficial to both parties.


hello tutor’s unique design means it is both easily replicable and highly scalable and as such is able to impact the lives of millions. This remains the core vision of hello tutor. In the 18 months of being “live”, hello tutor has amassed over 1400 video tutorials in English, Zulu and Afrikaans across maths and science from grade 8 to grade 12 and touched the lives of over 5000 South African learners. During this period, over 700 tutors have registered on the platform.

In addition to the teachers who register independently, hello tutor also pursues partnerships with leading schools as a means of growing our tutor population. Through school group scheme agreements, selected schools use hello tutor as an outsourced flipped/blended learning platform at no cost, and in so doing make high-quality video material available to the greater hello tutor-student community. This serves to further enhance our video library and will facilitate the addition of other subjects, notably English, Geography and Life Sciences to our high school coverage in the near future and many more over the medium term. It is through partnerships such as these, as well as with the general tutor population, that we see the available video content continuing to grow (currently growing at approx. 100 videos per month) and diversify.

Its a numbers game…

hello tutor as a platform thrives on high volumes of users -the more tutors involved, the more video material is generated across various subjects, in multiple languages and in a variety of styles. The more students using the site, the more videos are watched and the more the tutors are rewarded. It’s a win-win system with few constraints (no classrooms, no operating hours) that has the potential to change the face of education in developing markets, starting here in South Africa, and bring the highest level of teaching to learners from the most disadvantaged backgrounds.


Middle to Upper LSMs

For the middle to upper LSM hello tutor-student population accessing the platform through the internet, each video lesson can be purchased for R2 and watched repeatedly within a 48-hour time period at no additional cost. Once expired it needs to be purchased again. For this group, the Internet-based resource works well as it enables learners to revise and catch up using local curriculum aligned video lessons from any smart device. From a cost perspective too, the cost of one extra lesson with a private tutor equates to between 150 and 250 video lessons on hello tutor! On this option, there are no registration costs or subscription costs. Learners simply pay per video they purchase.

Hello tutor has recently introduced a subscription option which provides learners unlimited access to all content on the system for R49 per month.

Lower LSMs

For the vast majority of South Africans, the cost of each video lesson, getting credit onto the system and broadband requirements to watch streaming video represents an obstacle to accessing our educational library. To solve this problem, hello tutor partners with the public and private sector to bring hello tutor hubs into previously disadvantaged areas around the country.

What is a hello tutor hub?

Essentially, a hello tutor hub comprises a server loaded with a version of the online hello tutor library of lessons. This enables the following;

  1. Servers provide learners at schools and within community centres with unlimited access to the math and science video tutorial library through any smart device;
  2. Because all interaction with hello tutor is done through local wi-fi there is no need for internet connectivity which means no data costs;
  3. Local hubs are super-fast and enable streaming of content throughout locations i.e. all classrooms within a school;
  4. Local hubs allow between 50 and 100 learners to stream different video content simultaneously;
  5. Because no internet is required, hubs can be put in rural locations. This ensures no-one is excluded;
  6. Hello tutor hubs and the students accessing them still benefit from the organic and ever-growing nature of content on the online system.


Here are some of the notable developments since the Britehouse (Dimension Data) / hello tutor collaboration began in late 2015;

  • The number of high school math and science videos, all from leading South African teachers, made available through the platform has grown to over 1500 videos;
  • Of the 1500 videos, 300 grade 10 to 12 maths and science videos are in Zulu providing many learners with the opportunity to understand maths and science concepts in their own language (currently a further 200 Zulu videos ready to be uploaded);
  • The hello tutor video library continues to grow by over 100 videos per month;
  • Over 80% of the maths topics included in the NSC high school maths syllabus are covered by video material on hello tutor. The full syllabus will be covered by June 2017;
  • Both the 2014 and 2015 NSC matric maths final exam papers and the 2015 NSC matric science final paper have been covered by our tutors. Each question is answered in video tutorial format and allows learners to gauge their readiness for the exam. Not only are they able see whether they get the answers correct or incorrect, but exactly where they are making mistakes.
  • Leading South African Schools including St Mary’s, Waverley and prominent publishing house Via Afrika have engaged with hello tutor and begun contributing video tutorials to the platform. This has enabled us to broaden the scope of the platform into new subject areas such as geography as well as extend the maths coverage down to grade R.


Britehouse (a division of Dimension Data) have through the #67DayDigitalActivation movement pioneered the installation of hello tutor hubs in five under-privileged schools around South Africa. These schools include Sunrise Secondary School, Diepsloot; Kwena Molapo Comprehensive Farm School, Lenasia; Shumayela High School, Umlazi; Zwelibanzi High School, Umlazi and Newhaven Secondary School in Chatsworth. In terms of adoption, since the project began with the installation of the first servers in April 2016, hello tutor has seen the registration of over 650 individual learners in the five schools across the country. Amongst these learners, there have been over 2 500 sessions and 7 000 video tutorial lessons watched through hello tutor with, in many cases, a session including more than one learner watching a video.

The average session duration across the first four schools in 2016 was 26.7 minutes highlighting the fact that in many cases videos were either watched multiple times or multiples videos were watched per session. In 2017, we have seen this figure increase to over 39 minutes per session further highlighting the value learners are finding in the system.

With much of January and February 2017 being spent settling into the school year, we are delighted to see system usage picking up again.

Impact – Maths and Science

It has been extremely rewarding and inspiring to witness and contribute to the dramatic improvement in the matric results at two of the biggest adopters of the hello tutor hubs. These schools include Kwena Molapo High School in Lanseria and Shumayela High School in Umlazi. At Britehouse’s flagship school, Kwena Molapo High School a 100% matric pass rate was achieved for the 2016 year. Over 50% of students achieved bachelor passes and a further 38.75% receiving diploma passes.

Shumayela Secondary School situated in the heart of Umlazi improved their matric pass rate from 57% in 2015 to 84% in 2016 (an all-time record for the school) with a 100% pass rate in science.


Through the integration of hello tutor into these under-resourced schools, teachers are also able to leverage the wealth of information provided by the video tutorials. They can also draw upon the expertise and methodologies of teachers around the country in their own teaching and lesson planning.

The Vision

Our vision for hello tutor in 2017 and going forward is as follows;

  • To increase the number of hubs from 5 to 50. And then, to have a hello tutor hub within 5km of every South African. This will ensure every learner has access to the highest quality learning material within a reasonable walking distance;
  • Develop a mobile application which will allow learners to not only access hello tutor at hub sites, but be able to take it home with them;
  • To continue to develop and expand our video tutorial library across grades, subjects and particularly languages. This, to achieve an eco-system of learning material as rich and diverse as the people it aims to serve;
  • To reward more and more educational professionals. We do this by providing them with a real passive income generating option and amplifying the impact which their teaching has; and,
  • And finally, doing all of the above in a commercially sustainable manner ensuring the platform has the necessary longevity and sustainability to continue to serve South Africans and other learners for generations to come.

The Dream

It is our dream to have hundreds of hubs scattered around the country each delivering unlimited, “free to the consumer” access to high-quality educational content while still benefitting from an organically, constantly growing, internet leveraging platform. With each hub having the capacity to support thousands of learners at each school or tens of thousands when used centrally by a community, hello tutor provides a very real means of bridging the gap in the level of education received by privileged and underprivileged learners in developing countries. Britehouse, our main corporate sponsor, was awarded the prestigious SA Biz Awards CSI initiative of the year accolade at the end of 2016 for their support of and collaboration with hello tutor in developing a high impact, replicable and easily scalable means of bringing education to the people.


hello tutor seeks to remove inequality from education. It does so by tapping into the substantial pool of, what is for many, inaccessible teaching talent in developing markets and efficiently delivering educational content to those in need. Our unique and innovative solution allows us, through collaboration with philanthropic organizations in the private and public sector, to bring to thousands of under-serviced learners, educational video content of the highest order. With hello tutor’s design enabling rapid scalability, it’s non-reliance on internet connectivity and it’s cost effectiveness, our vision is to take the current hub network from 5 to 50 before the end of 2017. In the not too distant

With hello tutor’s design enabling rapid scalability, it’s non-reliance on internet connectivity and it’s cost effectiveness, our vision is to take the current hub network from 5 to 50 before the end of 2017. In the not too distant future, we hope to have a hub within walking distance of every South African. The journey thus far has been an extremely fulfilling, rewarding and enriching one (for all involved). It’s been one which has benefitted learners who through circumstance have been put on the back foot early on in life. Most importantly though, one which has just begun…

5th habit to becoming an excellent maths performer

For everyone

Think Logically

Excellent Math Performers have a habit to predict possible answers or think about reasonable answers. If you are working out the side length of a triangle and you get a negative answer – you might have made a mistake somewhere, because lengths should be positive. Here are some common logical arguments that might help you in reasoning about answers and predicting possible outcomes:

  1. Lengths are positive
  2. The term number of a number pattern is always positive – I can’t find the (-10 th) term.
  3. I can’t divide by zero
  4. I can’t find the square root of a negative number…. Also if I square something – it should be positive (bigger than or equal to 0)
  5. If I’m working out the height of a building – 0.3 metres and 120 km are ridiculous answers. 2.7 Metres is a perfectly acceptable answer.
  6. If I’m working with a number of students, animals, books, etc. decimal numbers are not valid answers – I need a positive integer as an answer, so if I get 2,6 students, I’ll answer 3 students.
  7. Similarly – if I predict the outcome on a dice – it should be a positive integer between 1 and 6. It can’t be 8 or 12,4 or -4
  8. The answers of sin and cos should lie between -1 and 1. Pi is 3,14… and is not a valid answer. If sin(x) gives an answer of 3pi, I’ll check my calculator settings. You also can’t find if x is smaller than -1 or bigger than 1.

4th habit to becoming an excellent maths performer

Fix Your areas of weakness

Constantly review your work. Develop a habit to check every problem for mistakes. Make sure you’ve added up correctly by double-checking with your calculator. Work out difficult problems in two different ways and see if you get the same answer.

Get in the habit of finding your mistakes and fixing them.

Another great tool to use to fix your weaknesses is a list of mistakes or errors. Here’s a few examples of errors/mistakes:

  1. You know you always forget to write the units at the end of a question
  2. You forget to convert different units in one problem to the same unit (you can’t use cm, m and mm in one problem, you must convert them all to one, for instance convert all to cm)
  3. You get so busy with solving you forget that the question asked the coordinate pair (x;y) and you never finish working out y also
  4. You multiply x-values in your head when you should add them

So make a list of all the usual mistakes you make and write down how to fix them or what you should do instead. Then go through that list after completing an exercise to check

whether you’ve made some of your usual mistakes and fix them. You can also revise the list before every test and exam to make yourself aware of the mistakes.

This way you train your brain to not lose marks on silly little mistakes.

3rd habit to becoming an excellent maths performer


Create Your own Study Material

Make your own notes to study from. You know yourself very well. Only you can create notes customised to suit your own needs. A teacher’s notes or friend’s notes might help, but you are better off studying from your own notes. Let me tell you why:

  • Your notes should reflect your own learning style. Some people learn better from pictures and diagrams, some people learn better from lists. One person prefers examples of the problems, another prefers a short explanation of the method and yet another only needs to know what the formulae are and how to apply them. Include the things in your notes that will help you learn best!
  • What do you need to study? You only need to study the things you don’t know… For example, you are learning about shapes in the classroom. You might know perfectly well what a rectangle is, you don’t need the definition in your notes. But you might be uncertain about the definition or even just the spelling of a parallelogram. You need to study the parallelogram and need that in your notes.

If your notes contains a lot of information which you already know – you waste valuable time while studying, going through things you know and you tire yourself before you start going through the things you didn’t know.

  • You learn from various resources – your teacher, your textbook, your exercise book, a tutor, a friend, extra textbooks, the internet, etc.

By making your own notes, you can combine the information in one place. You should constantly update your notes with information from all of the resources listed above, so that by the time the exam starts – you’re not feeling overwhelmed and all over the place. You know that everything you need to know is organised in one file or one notebook. You can simply go through your notes and maybe work out one or two practise papers.

  • Make a list of words with its definitions. Create a little dictionary of Mathematics words where you can look up the meaning if you need to. Keep this list with your notes and keep it for next years also – you can build onto it and refer back to past years.
  • Mathematics is a cumulative subject. Knowledge and concepts are constantly being built on previous knowledge. If you have notes from previous years – it gives you something to fall back on if you realise that you don’t remember past knowledge.

This nonsense that teachers are paid less than other professionals is crazy – how do we expect to attract talent to a sector responsible for the education of future leaders?

One of hundreds of maths video tutorials in our online library

Here is an excellent example of a maths video tutorial uploaded by one of our leading tutors. Videos such as this are available on demand and can be purchased for only R2.00. Each purchase buys you the video for 48 hours of viewing. If you compare to the cost of an extra lesson it’s a real no-brainer. We would love to hear you thoughts on this and other content on hello tutor.
