Digital solution for literacy?

Published

The country’s reading crisis has once again come into the spotlight through the latest findings of the Progress In International Reading Literacy Study which reveals that as many as 78% of Grade 4 children cannot read.

There is a solution to the Foundation Phase reading crisis that the education system in South Africa currently faces. The early introduction and integration of digital tools in the classroom can and has proven to improve literacy levels amongst children, a SchoolNet South Africa (SNSA) study has found.

The country’s reading crisis has once again come into the spotlight through the latest findings of the Progress In International Reading Literacy Study (PIRLS). It has revealed that many of country’s children are struggling to read; that as much as 78% of Grade 4 children cannot read for meaning in any language.

While the research study of this project, called Learning Gains through Play (LGP), showed learning gains in all foundational literacies tracked, the most interesting findings were of gains in oral English language skills acquired subconsciously through play by second language learners.

The Methodology:

Ten schools in KwaZulu-Natal and the Western Cape each received a bank of learner tablets and an Xbox Kinect (including carefully selected apps and games) which, along with intensive teacher development and support, were integrated in teaching and learning activities in Grade R and Grade 1 classrooms. Learners were tracked over a four year period to assess their progress in foundational skills.

Data was compared with control school learners who were assessed and tracked in the same manner (but did not enjoy the benefits of any of the LGP project inputs). Results showed improvements in achievement in all five foundational literacies of gross-motor skills, fine-motor skills, numeracy, visual literacy and oral English communication skills.

This last literacy is of particular interest as the learning gains were substantial and furthermore, because the language of learning and teaching is a hotly debated topic in South Africa. With eleven official languages there is little consensus on which is more beneficial, for children to learn in their mother tongue or in the universal language of English.

This issue is particularly contentious in the first grades of Foundation Phase in South Africa. SchoolNet’s Learning Gains through Play project has shown that in the early grades, children can acquire English language skills “on their own” through engaging with learning games and apps that use English as the medium of instruction.

This acquisition of English is very different to the formal learning of a language with its structures and rules. Acquisition is a subconscious immersive method to understand and make meaning, similar to the way in which babies learn their mother tongue.

For the LGP children learning was mediated by their educators; it was not really learning “on their own” but learning driven by a need to make understanding of the games and apps in order to engage and entertain themselves with the digital tools that they found so exciting. One of the LGP findings was that learners’ curiosity was sufficiently enabled to trigger self-driven learning.

The theory of second language acquisition (SLA) was proposed by linguistic professor Stephen Krashen (1981) and according to Krashen and Terrell (1995), students learning a second language move through five predictable stages: Preproduction, Early Production, Speech Emergence, Intermediate Fluency, and Advanced Fluency.

“With the majority of learners in South Africa learning in their home language in Foundation Phase and then making an abrupt switch to learning in English from Grade 4 (and this coupled with the addition of three more subjects), providing tablets, Xboxes, apps and games in English for learners in the early grades is an effective strategy for preparing learners for success in the Intermediate Phase and beyond,” says SNSA’s Executive Director, Janet Thomson.

The worst hit from the reading crisis are poor and disadvantaged children, who make up 25% of the population who live in extreme poverty. An alarming fact is that learning deficiencies in the early grades accumulate and have a far greater detrimental impact in later grades and across all subjects including Mathematics.

Only the top 16% of Grade 3 Maths students are achieving at the Grade 3 level (Spaull & Kotze, 2015). Clearly the vast majority of South African learners are not meeting the curriculum requirements even at the very start of their journey through the schooling system.

In addition to the county’s poor reading culture, reading is also generally taught badly resulting in what the The Conversation has dubbed a “cognitive catastrophe”.  The publication argued recently that “failing to learn to read is bad for the cognition necessary to function effectively in a modern society.” This essentially means that we are raising generations of cognitively stunted individuals who then become stuck in intergeneration poverty.

One of the reasons why the PIRLS Study tested 13 000 Grade 4 children is because it is in the Foundation Phase “that the base for all future learning is established, and if the rudiments of reading, writing and calculating are not firmly entrenched by the end of Grade 3, then both learning opportunities and the larger life chances of young citizens will be curtailed” (National Education, Evaluation and Development Unit, 2013).

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

Buy 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

Pizoelectrics: Healthcare’s new gymnasts of gadgetry

Published

on

Healthcare electronics is rapidly deploying for wellness, electroceuticals, and intrusive medical procedures, among other, powered by new technologies. Much of it is trending to diagnostics and treatment on the move, and removing the need for the patient to perform procedures on time. 

Instruments become wearables, including electronic skin patches and implants. The IDTechEx Research report, “Piezoelectric Harvesting and Sensing for Healthcare 2019-2029”, notes that sensors should preferably be self-powered, non-poisonous even on disposal, and many need to be biocompatible and even biodegradable. 

We need to detect biology, vibration, force, acceleration, stress and linear movement and do imaging. Devices must reject bacteria and be useful in wearables and Internet of Things nodes. Preferably we must move to one device performing multiple tasks. 

So is there a gymnast material category that has that awesome versatility? 

Piezoelectrics has a good claim. It measures all those parameters. That even includes biosensors where the piezo senses the swelling of a biomolecule recognizing a target analyte. The most important form of self-powered (one material, two functions) piezo sensing is ultrasound imaging, a market growing at 5.1% yearly. 

The IDTechEx Research report looks at what comes next, based on global travel and interviewing by its PhD level analysts in 2018 with continuous updates.
