In this blog post, we’ll examine how digital media and cutting-edge technology affect our learning and thinking abilities through various examples.
The Convenience and Questions Raised by Digital Media
Unlike in the past, when we had to go to the library to find information, we can now quickly get answers by turning on a computer and typing keywords into a search engine whenever we have a question. It has become commonplace to make payments via smartphone without visiting a bank, shop online without going to a store, and type on a laptop keyboard instead of taking notes in class. While digital media has made our lives more efficient and convenient, the question remains: have people actually become “smarter” as a result?
Case 1: The Backlash of Highly Assistive Learning Software
In 2003, a clinical psychologist in the Netherlands conducted an experiment to investigate the impact of computer-based learning programs on learners. Participants were divided into two groups and asked to solve a challenging logic puzzle involving moving colored balls according to specific rules. One group used software designed to provide as much assistance as possible, while the other group used a simple program that offered no hints or advice whatsoever.
As expected, the group using the software that provided extensive assistance initially found the correct moves faster. However, as the experiment progressed, the group using the software that provided minimal assistance improved their proficiency more rapidly and eventually solved the puzzles more efficiently. This case demonstrates that tools designed to aid problem-solving may appear advantageous at first but can hinder the development of independent thinking and skill improvement in the long run.
Case 2: Are Multimedia Lessons Really Effective?
Multimedia lessons utilizing audiovisual materials and various graphics are widely used in schools today. However, it is questionable whether multimedia actually improves learning outcomes. In one study, participants were shown presentation materials; one group was given a text-only document, while the other group was shown multimedia that included text along with audio and visual presentations. When comprehension was later measured with 10 questions, the group that read only text answered more questions correctly on average, and in a survey, they also rated the presentation as more interesting, educational, and easier to understand.
In a similar vein, a university research team compared a group of students who were shown a typical news report with various graphics and subtitles on the screen to a group that was not. The results showed that those who viewed the multimedia format with graphics and subtitles remembered less of the news afterward than those who viewed the simple format. As these findings accumulated, reports emerged that even in Silicon Valley—the heartland of cutting-edge technology—some parents are sending their children to schools that use only traditional teaching aids, without digital devices such as computers, screens, or projectors. They worry that digital devices may harm creative thinking and attention span.
Case 3: The Limitations of Hypertext Reading
In the online environment, people often read books or academic papers in hypertext format on tablets or monitors rather than reading them linearly on paper. Hypertext has the advantage of allowing users to instantly find desired information through indexes or links, and it offers the convenience of being able to search for answers immediately if questions arise while reading.
However, an experiment conducted by Canadian researchers in 2001 observed that such hypertext actually hinders comprehension. When test subjects were asked to read a short story, those who read it as a linear document understood the content relatively quickly and accurately, whereas those who read it as hypertext via links took longer to read and, in subsequent interviews, showed signs of not fully understanding the content or appearing confused. About three-quarters of those who read the hypertext reported difficulty in reading through it, whereas only about one in ten of those who read the linear document reported similar difficulties.
Conclusion: The Choice Between Convenience and Preserving Our Abilities
As the above examples show, electronic media and advanced technology have made our lives more convenient, but at the same time, they carry the risk of weakening our ability to think independently or achieve deep understanding.
It is a paradoxical situation where tools created to help humans maximize their potential may actually limit those very abilities.
Therefore, rather than unconditionally embracing electronic media, we need to evaluate its influence from a critical perspective and adopt a cautious approach to its use. Whether to pursue convenience at the cost of losing our intellectual sharpness, or to maintain our thinking abilities even if it means accepting some inconvenience, is a matter of choice—and the latter choice is well worth making.
