Mobile technology has transformed the way we live and work, and it can be expected to rapidly change the ways in which children learn as smartphones and tablets become more widely accepted at primary and high schools. By putting a powerful computer in every learner’s schoolbag or pocket, smartphones could play an important role in improving educational outcomes in a country where so many schools are under-resourced.
Here are some ways that mobile technology will reshape education in the years to come:
Organisation and productivity
For many adults, the real benefit of a smartphone comes from simple applications like messaging, calendaring and email. The same goes for schoolchildren, many of whom will get the most value from basic apps like sending a WhatApp message to friends to check on the homework for the day, keeping track of their extramural calendar, or photographing the teacher’s notes from the blackboard or whiteboard. One study of young people’s mobile phone use in Ghana, Malawi and South Africa confirmed that many of them got the most value from using their phones to complete mundane tasks.
One of the major benefits smartphones can bring to the classroom is boosting learners’ engagement with educational materials through rich media and interactivity. For example, apps like Mathletics use gamification to get children excited about doing mathematics—they turn learning into a game, with rewards for practicing and hitting milestones. Or teachers can set up a simple poll using an app like Poll Everywhere to ask the children in a class what they think about a character’s motivation in their English set-work book.
Mobile technology opens the doors to more
For example, teachers can provide recommended educational materials for children who are racing in ahead of their peers in some of their subjects. Or they can suggest relevant games for children who learn better through practical application of ideas than by listening to a teacher and taking notes.
In future, we can expect to see teachers, perhaps aided by algorithms and artificial intelligence, make use of analytics to track how students engage with educational content on their mobile devices and use these insights to create more powerful learning experiences.
South Africa has a shortage of teachers in key subjects such as mathematics and science, which disproportionately affects learners in poor and rural areas. According to a statement in 2017 from the Department of Basic Education, it has more than 5,000 underqualified or unqualified teachers working around the country. Though technology cannot substitute for a qualified teacher, it can supplement human teaching in remote or poor areas where teachers are not available or not qualified to teach certain subjects. Video learning and videoconferencing sessions offer the next best thing where a math or physical science teacher is not physically present in the classroom.
Knowledge is power and the Internet is the world’s biggest repository of knowledge. Schoolchildren can access information and expertise about every subject under the sun from their smartphones – whether they are reading the news on a portal, watching documentaries on YouTube, downloading electronic books, using apps to improve their language skills, or simply Googling facts and figures for a school project.
Take a mobile-first approach
Technology has a powerful role to play in the South African school of the future, but there are some key success factors schools must bear in mind as they bring mobile devices into the classroom:
- Use appropriate technology—in South Africa, that means taking a mobile-first approach and using the smartphones many children already know and use.
- Thinking about challenges such as security – put in place the cyber and physical security needed to keep phones and data safe and secure.
- Ensuring teachers and children alike are trained to make the most of the tech – teachers need to take an active role in curating content and guiding schoolchildren’s use of their devices. To get that right, they will need training and access to reliable tech support.
AI, IoT, and language of bees can save the world
A groundbreaking project is combining artificial intelligence and the Internet of Things to learn the language of bees, and save the planet, writes ARTHUR GOLDSTUCK
It is early afternoon and hundreds of bees are returning to a hive somewhere near Reading in England. They are no different to millions of bees anywhere else in the world, bringing the nectar of flowers back to their queen.
But the hive to which they bring their tribute is no ordinary apiary.
Look closer, and one spots a network of wires leading into the structure. They connect up to a cluster of sensors, and run into a box beneath the hive carrying the logo of a company called Arnia: a name synonymous with hive monitoring systems for the past decade. The Arnia sensors monitor colony acoustics, brood temperature, humidity, hive weight, bee counts and weather conditions around the apiary.
On the back of the hive, a second box is emblazoned with the logo of BuzzBox. It is a solar-powered, Wi-Fi device that transmits audio, temperature, and humidity signals, includes a theft alarm, and acts as a mini weather station.
In combination, the cluster of instruments provides an instant picture of the health of the bee hive. But that is only the beginning.
What we are looking at is a beehive connected to the Internet of Things: connected devices and sensors that collect data from the environment and send it into the cloud, where it can be analysed and used to monitor that environment or help improve biodiversity, which in turn improves crop and food production.
The hives are integrated into the World Bee Project, a global honey bee monitoring initiative. Its mission is to “inform and implement actions to improve pollinator habitats, create more sustainable ecosystems, and improve food security, nutrition and livelihoods by establishing a globally-coordinated monitoring programme for honeybees and eventually for key pollinator groups”.
The World Bee Project is working with database software leader Oracle to transmit massive volume of data collected from its hives into the Oracle Cloud. Here it is combined with numerous other data sources, from weather patterns to pollen counts across the ecosystem in which the bees collect the nectar they turn into honey. Then, artificial intelligence software – with the assistance of human analysts – is used to interpret the behaviour of the hive, and patterns of flight, and from there assess the ecosystem.

Download speeds ramp up in SA
All four South African mobile network operators have improved their average download speed experience by at least 1 Mbps in the past six months.
This is one of the main findings in the latest South Africa Mobile Network Experience report by Opensignal, the mobile analytics company. It has analysed the mobile experience in the country, updating a study last conducted in February 2019. While a quick look at its South Africa awards table suggests not much has changed since the last report, it’s far from stagnating.
Opensignal reports the following improvements across its measurements:
- MTN remains the leader in our 4G Availability measurements, with a score of 83.6%. But the other three operators are all now within 2 percentage points of the 80% milestone — with Telkom’s users seeing the biggest increase of over 8 points.
- All four operators improved their Download Speed Experience scores by at least 1 Mbps. But growth in our Upload Speed Experience scores has stagnated, with only winner Vodacom seeing an incremental increase.
- MTN and Vodacom remain tied for our Video Experience award, and both have increased their scores in the past six months, putting them on the cusp of Very Good (65-75) ratings. Cell C also increased its score to tip over into a Good ranking (55-65).
- MTN scored over 90% in 4G Availability in two of South Africa’s biggest cities and was just shy of this milestone in the others. Meanwhile, MTN and Vodacom have now passed the 20 Mbps mark in Download Speed Experience in three cities each.
A quick look at the awards table would suggest not much has changed in South Africa since the last report in February. MTN won the 4G Availability award again, Vodacom kept hold of the medals for Upload Speed and Latency Experience, while the two operators tied for Download Speed and Video Experience just as they did six months ago.
But far from stagnating, we’re seeing improvements across most of the measurements. All four of South Africa’s national operators — Cell C, MTN, Telkom and Vodacom — are now closing in on 80% 4G Availability nationally, while at the urban level, MTN has passed the 90% mark in two cities. And in Download Speed Experience, our users on all four operators’ networks saw their scores increase at least 8%.
In this report, Open Signal has analyzed the scores for all four national operators across all their metrics over the 90 days from the start of May 2019, including South Africa’s five biggest cities — Cape Town, Durban, Ekurhuleni, Johannesburg, and Tshwane.
MTN has been top of Open Signal’s South African 4G Availability leaderboard for a couple of years now, and the operator remains dominant with a winning score over 4 percentage points ahead of its rivals. But it was users on Telkom’s network who saw the most impressive boost in 4G Availability, as its score jumped by well over 8 percentage points.
This leap has put Telkom into a three-way draw for second place with Cell C and Vodacom, who both saw their scores increase by at least 3 percentage points.
While MTN is the only operator to have passed 80% in national 4G Availability, the other three players are all less than 2 percentage points away from this milestone. Based on the current rate of improvement, Open Signal fully expects to see all four operators pass the 80% mark in its next report — which will provide testament to the rapid maturing of the South African mobile market.
MTN and Vodacom remain neck-and-neck in the Video Experience analysis, with both operators scoring 65 (out of 100). And the two rivals both saw their scores rise by around 3 points since our last report, meaning the two continue to share our Video Experience award. Cell C and Telkom remain in third and fourth place, but both saw larger increases — of 5 and 4 points respectively — to narrow the gap on the leaders.
The increase in MTN and Vodacom’s Video Experience scores means the two operators are on the cusp of Very Good (65-75) ratings in this metric — with the users on their networks enjoying fast loading video times and almost non-existent stalling, even at higher resolutions. By comparison, Cell C’s score earned it a Good rating (55-65), while Telkom remains in Fair (40-55) territory — meaning users watching video on Telkom’s network, in particular, will likely struggle with longer load times and frequent stuttering, even at lower resolutions.
In terms of 4G-only Video Experience, Cell C’s score has increased enough to tip it over into a Very Good rating — now featuring three operators achieving 4G network scores with a Very Good ranking. And as 4G Availability continues to increase, the overall Video Experience scores will continue to climb, making mobile video viewing more of a viable proposition across all networks. And in a country where fixed-line broadband connections are relatively rare and the large majority of South Africans only connect to the internet via cellular, this improvement has the potential to transform people’s lives.
