One of the oldest adages in marketing is “Half the money I spend on advertising is wasted, but I don’t know which half.” It’s as important for advertisers to reach the right people as it is to make an appealing ad, so they have developed many different ways of targeting ads effectively. Online advertising lets marketers match different ads with individual users. This section looks at how that’s done and how it affects kids’ privacy.
In this lesson, students will learn about algorithms and how they function, particularly recommendation algorithms utilized by popular apps like YouTube, TikTok, Instagram, and Netflix. Students explore the role of optimization goals such as watch time, engagement, and daily active use in shaping the content algorithms prioritize. Through activities like “red teaming,” students will critically analyze the potential downsides and biases of these optimization goals. Students will also discover how to train algorithms by providing both explicit inputs through actions like liking and sharing, and understand the implications of implicit inputs gathered from their online activity. Finally, students design their own algorithm for an app of their choice, identifying which goals it should be optimized for and how they should be weighted as well as what inputs it should use.
It's been widely said that attention is the currency of the 21st Century. In an age where media occupy an increasingly central role in our lives, the need to have that media focused on you becomes intense. For no-one is this more true than for children and teens, who now expect to be connected twenty-four hours a day and for whom the Internet and cell phones are essential parts of their social lives. An interesting Facebook page, amusing Tweets, outrageous YouTube videos, even shocking photos sent by cell phone -- most of us are aware of the ways that young people seek their peers' attention. In today's media environment, is it still possible to teach young people the value of privacy? What, indeed, does the idea of privacy even mean to today's children and teens?
It’s easier than ever to know the whereabouts of your family and friends. There are devices you can buy with wearable GPS systems. Effectively, you can be traced and tracked by loved ones.
In this lesson, students discuss their experiences playing free online games and then learn the costs of these “free” games in the form of paying with money, sharing personal information or providing attention to advertising or branded content. Students then learn a variety of techniques for mitigating the risks and drawbacks of online games and communicate their learning by describing one of these techniques in video-game terms.
Cyber Choices is an interactive game designed to help students in grades 3 to 5 develop the skills and habits they need to make safe and responsible choices online. Cyber Choices lets students explore four different stories that cover key issues such as making good choices about their own and others’ personal information, dealing with cyberbullying (as both a target and a witness) and managing online conflict.
In this lesson, students learn the concept of the Dual-Shield Defense for cybersecurity: The Outer Shield (Technical Perimeter Defenses): Automatic, structural blocks that prevent risks from ever reaching a user's account or device. This includes DNS (domain name system) filtering tools such as CIRA Canadian Shield, ad blockers, multi-factor authentication (MFA), and device-level Stolen Device or Theft Protection. The Inner Shield (Human Cognitive Verification): Active mental habits that allow users to spot, analyze, and neutralize scams that get past the outer shield. This includes detecting psychological triggers (Urgency, Fear, Authority, Secrecy), applying the "Take Five, Tell Two" rule, and using robust offline verification protocols.
