The importance of digital literacy and the internet

The American Library Association defines digital literacy as “the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills.”

Digital literacy includes something most of us do daily: the ability to check and read our emails on a digital device like our cellphone or tablet.

Digital literacy is also the ability to conduct online research to learn more about a subject, either for personal knowledge, work or school. 

Simply using a search engine to discover an answer to a question or creating a profile of yourself on a social media account are examples of your digital literacy. 

According to Statista, over 90% of Americans have internet access. The internet has proven to be an invaluable tool in our daily lives, especially since the onset of the worldwide pandemic in 2020 drove our workplace, educational institutions, grocery stores and even our medical offices online.

Digital literacy is important for all stages of our lives, from young students attending school virtually to older computer users accessing their doctor or staying in touch with family.

6 reasons why digital literacy can improve your life

1. Making connections with family and friends

Being social is in a human’s nature and staying in touch with our family and friends can benefit our mental health. In fact, “social media has become a source of internal healing for a lot of senior citizens battling depression,” according to the Miami Home Care Services. 

2. Increased safety

With digital literacy comes understanding good online safety practices that can help to increase your safety – from protected passwords to recognizing signs of spam.

3. Save time

Being digitally literate can save you time, whether you have an online appointment call with your doctor, do your shopping online or take a virtual class. Think of all the time you save by not driving, standing in line, etc. 

4. Supports lifelong skills

Nearly everything we do requires some level of digital literacy. Many companies require an online application or an emailed resume to apply for open positions. Our patient portals are online, as are many government assistance agencies. 

5. Helps educational progress

Not only will digital literacy help your student with research and social skills, but it will also allow them to learn how to stay safe online

Post-pandemic, many educational institutions have adopted a hybrid approach to education, with most classes being held in person, but some assignments and classes are still accessible online. Parents can often access their student’s classroom portal and keep track of grades and assignments, as well as handle communications with educators. 

6. Close the digital divide

Access to technology in our post-pandemic world is essential. However, there is still a digital divide in the U.S., mostly in rural areas, but also in pockets of urban areas. 

The digital divide is the division between individuals who have access to computers and high-speed internet and those who do not. 

For students, this is particularly worrisome, as they risk falling behind their classmates. According to a Pew Research Center survey, “24% of teens living in lower-income households often or sometimes are unable to complete homework due to lack of reliable computer or internet access.”

To combat the digital divide, the federal government has implemented the Affordable Connectivity Program, which partners with internet service providers to offer high-speed internet plans for $30/mo., which will allow anyone qualified to receive the $30/mo. stipend from the Affordable Connectivity Program (ACP) to get internet service for free.
