With the spread of the Internet, people are now equally exposed to a vast amount of information. This includes, of course, misinformation and malicious disinformation. In addition, in the past few years, there has been an increase in the amount of information about wars, politics, and other issues that are viewed from completely different perspectives depending on one's position.

Students need to verify information.

Being able to differentiate false information is especially important in schools. Students are accessing the internet for schoolwork more often in recent years. On top of that, active learning and programming education have accelerated the usage of the internet even more.The skill of being able to access correct information is essential, yet it is not under the spotlight nearly as often.

Over 80% of students are unable to verify false information.

According to a study by the Ministry of Internal Affairs and Communications of Japan, 15-19 year olds are most likely to be deceived by false information online.
Students are at the most risk when it comes to misinformation and harmful disinformation.

Students are most likely to...

Lessons taught in
Ray's Blog

Finding primary information.
In fact-checking, the act of "searching" is fundamental. When one comes across an article or post with questionable content, it is important to first search for it using a search engine such as Google and compare it with primary information from credible news organizations and public institutions. At the same time, it is important to pay attention to the "when and by whom" the information was spread and the "citation source" of the information.
Social media awareness.
Social media sites are filled with a lot of false information. According to a study done by the Japanese government, about 30% of all respondents saw fake news on social networking sites and blogs at least once a week. This is why it is easy for misinformation and fake news to spread as well.
Invasion of short-form videos.
Nowadays, short-form video content distributed on TikTok and YouTube has become mainstream among the younger generation. Information that is complex or requires additional context is difficult to convey accurately in a short amount of time, and inaccurate information can easily spread.
Geo-point Location.
Geo-point location is the ability to identify a location from video and images.Such skills can be useful in response to fake images and videos that tend to be spread during times of turmoil, such as war. For example, if an image that has nothing to do with war is spread as an image of war, the information in the image can be used to identify the location, thereby establishing that the information is false.

In the review lesson, we will connect the actions you have taken so far in the game to the context of fake news, how to deal with misinformation, and examples of verification to help you realize the social value of the skills you have just acquired.

Since they are foreigners and in Japan, misinformation is a threat and with fraud being a problem, a program like this is a great way to learn Japanese and media literacy together.
