Acts Standards
Entry Events
Events that will be used to introduce the project to studentsThe Case of the Missing Grade
Students are presented with a fictional scenario: A student's grades have mysteriously plummeted, and the only clue is their mobile phone usage data. Students must analyze the data to determine if there's a correlation and present their findings as expert witnesses.App Addiction Confessions
The teacher shares anonymous confessions from students about their mobile phone habits and academic struggles. This sparks a class discussion about the potential impact of phones on learning, leading to the project's data analysis phase.Design Your Own "Digital Detox" App
Students brainstorm features for an app designed to help people reduce phone usage and improve focus. This exercise encourages them to consider the various ways phones can be distracting and motivates them to investigate the connection between phone usage and academic performance.Social Media "Trial"
Students participate in a mock trial where social media is "on trial" for negatively impacting academic performance. Some students act as prosecutors, others as defenders, and the rest as the jury. This debate format introduces the project's central question in an engaging and controversial way."Phone vs. Focus" Experiment
The class conducts a mini-experiment where students perform a focused task (e.g., reading comprehension) under two conditions: with and without phone access. They then compare their performance in each condition, creating a visceral experience of the potential impact of phones on concentration.Portfolio Activities
