What impact have technologies generated in this changing role?

Faced with the pandemic, countries have combined high-tech and low- tech approaches to help teachers better support student learning. In Cambodia, for example, education leaders designed a strategy that combines SMS, printed handouts, and continuous teacher feedback, taking advantage of the high mobile phone penetration in the country. The approach goes beyond providing low-tech materials: it gives information on how to access learning programs, ensures students access paper-based learning materials, and includes home visits to monitor distance learning activities. Teachers are also expected to provide weekly paper-based resources to students and meet them weekly to provide their marked worksheets and issue new ones for the weck ahead,

Technology has also enhanced government-teacher support, adapting existing coaching programs to be delivered remotely (as the mentioned cases of Nigeria and Uruguay), creating spaces for peer support programs (for example the Virtual EdCamps initiative, created to facilitate peer-topeer learning among teachers) or establishing EdTech hotlines for teachers (like in Estonia, where the HITSA - the Information Technology Foundation for Education - opened an educational technology information line to solve any technological question teachers might have).

Technology interventions should enhance teacher engagement with students, through improved access to content, data and networks, helping teachers better support student learning, as laid out in the World Bank's Platform for Successful Teachers, where effective use of technology is one of the key principles to ensure cadres of effective teachers.

In his book entitled ‘The McDonaldization of Society’, George Ritzer nicely encompasses concepts from sociology, management, and economics to provide a profound understanding of our modern society. According to George Ritzer, McDonaldization is defined as the process by which the principles of the fast-food restaurant are coming to dominate more and more sectors of American society as well as of the rest of the world. The success of McDonald’s is also evident worldwide as over half of the company’s revenue comes from overseas operations serving 50 million customers a day. Indeed, this fast-food restaurant has become more than just a company. It has become a part of our culture.

The boxer

I am just a poor boy, though my story’s seldom told
I have squandered my resistance for a pocketful of mumbles, such are promises
All lies and jest, still a man hears what he wants to hear
And disregards the rest

[05] When I left my home and my family, I was no more than a boy
In the company of strangers
In the quiet of the railway station, runnin’ scared, laying low,
Seeking out the poorer quarters, where the ragged people go
Looking for the places only they would know
[10] Lie la lie, lie la la la lie lie

Asking only workman’s wages, I come looking for a job
But I get no offers
Just a come-on from the whores on 7th Avenue
I do declare, there were times when I was so lonesome
[15] I took some comfort there

Now the years are rolling by me
They are rockin’ evenly
I am older than I once was
And younger than I’ll be; that’s not unusual
[20] Nor is it strange
After changes upon changes
We are more or less the same

After changes we are more or less the same
And I’m laying out my winter clothes and wishing I was gone
[25] Goin’ home
Where the New York City winters aren’t bleedin’ me
Leadin’ me
Goin’ home

In the clearing stands a boxer and a fighter by his trade
[30] And he carries the reminders
Of every glove that laid him down or cut him
‘Til he cried out in his anger and his shame
“I am leaving, I am leaving”, but the fighter still remains

Why do we need the law to protect personal data?

The right to have data protected is generally based on the Federal Constitution of 1988 [3]. The Federal Senate recently approved a Proposed Amendment to the Constitution (PEC No. 17/2019) to include the data protection made available in digital media in the individual guarantees list of the Constitution, expressing conformity to the principles. It was then up to the LGPD to regulate the protection and privacy of personal data to make its exercise possible. Thus, the Law No. 13,709 / 2018 (General Data Protection Law) affects the registration of users and customers, changing the way organizations should treat personal data, to protect the fundamental rights of freedom, privacy and to respect the free development of personality.

Regular exercise changes the structure of our bodies’ tissues in obvious ways, such as reducing the size of fat stores and increasing muscle mass. Less visible, but perhaps even more important, is the profound influence exercise has on the structure of our brains – an influence that can protect and preserve brain health and function throughout life. In fact, some experts believe that the human brain may depend on regular physical activity to function optimally throughout our lifetime.

Many studies suggest that exercise can help protect our memory as we age. This is because exercise has been shown to prevent the loss of total brain volume (which can lead to lower cognitive function), as well as preventing shrinkage in specific brain regions associated with memory. For example, one magnetic resonance imaging (MRI) scan study revealed that in older adults, six months of exercise training increases brain volume.

Another study showed that shrinkage of the hippocampus (a brain region essential for learning and memory) in older people can be reversed by regular walking. This change was accompanied by improved memory function and an increase of the protein brain-derived neutropic factor (BDNF) in the bloodstream.
