“make an assignment packet Day 8 Lesson Plan: Optimize Your Device Objective Students will identify and recommend operating-system and software settings that help a device work better for a particular user or goal. Word Bytes (Key Terms & Definitions) Optimize – To adjust something so that it works better for a particular purpose or goal. Accessibility – Features that make a device or application easier for people with different needs to use. Performance – How efficiently and reliably a device or application operates. Default Setting – A setting automatically selected unless the user changes it. Activities Hook: What Are the “Best” Settings? — 5 minutes Introduce the following two users: User A: A student is editing a video. Several applications are open, the device is running slowly, and very little storage remains. User B: A student has difficulty reading small text and identifying buttons on the screen. Ask students: Should both devices have exactly the same settings? What changes might help User A? What changes might help User B? What would it mean for each device to be “optimized”? Explain that optimizing a device means adjusting it to meet a particular user’s needs or goals. There is not one perfect set of settings for every user. Mini-Lesson: Settings Serve Different Goals — 8 minutes Review that the operating system manages a device’s hardware, applications, files, accounts, and settings. Explain that users can adjust operating-system and software settings for different purposes: Performance Close applications that are not being used. Free storage space. Reduce unnecessary startup applications. Install appropriate updates. Accessibility Increase text size. Increase contrast. Enable captions. Use screen magnification. Enable speech-to-text or a screen reader. Reduce motion or animation. Battery Life Reduce screen brightness. Enable battery-saver mode. Close unused applications. Turn off unused connections or features. Security and Privacy Shorten the automatic screen-lock time. Review application permissions. Install security updates. Use separate accounts on shared devices. Focus and Productivity Enable focus or do-not-disturb mode. Disable unnecessary notifications. Reduce animations. Use a distraction-free writing mode. Explain that changing a setting may help achieve one goal while creating a disadvantage elsewhere. Discuss examples: Increasing screen brightness may make the screen easier to see but use more battery. Shortening the automatic screen-lock time may improve security but require more frequent logins. Turning off notifications may improve focus but cause the user to miss an important message. Installing an update may improve security or performance but require time and a restart. Goal, Setting, and Tradeoff — 7 minutes Present students with several possible setting changes. For each change, students identify: the goal the change could help accomplish; how the change would help; one possible tradeoff. Suggested examples: Increase the text size. Reduce the screen brightness. Close unused applications. Enable captions. Shorten the automatic screen-lock time. Enable focus mode. Install an operating-system update. Discuss whether one setting can support more than one goal. For example, an operating-system update may improve security, performance, stability, or compatibility. Device Optimization Challenge — 17 minutes Place students in pairs and assign each pair a user scenario. Device Optimization Challenge Worksheet Students answer: What is the user trying to accomplish? What problem is preventing the user from reaching that goal? What two settings or actions would you recommend? How would each recommendation help? What tradeoff could each change create? How would the user know whether the changes worked? Scenario A: Video Editor A student is editing a class video. The device is running slowly, several applications are open, and only a small amount of storage remains. Scenario B: Small Text A student has difficulty reading small text and identifying buttons in an application. Scenario C: Long Bus Ride A student needs a laptop battery to last through a long bus ride but must also use it to write a report. Scenario D: Shared Classroom Computer Several students use the same classroom computer. The device remains signed in when students walk away, and several applications can access the camera and microphone. Scenario E: Distracted Writer A student is trying to complete an essay but is distracted by notifications, animations, and applications that open automatically. Scenario F: Noisy Classroom A student is watching an instructional video in a noisy classroom and cannot clearly hear the speaker. Students may locate the relevant settings on a device or use teacher-provided screenshots. Remind students: Locate settings and recommend changes. Do not change a setting unless your teacher specifically authorizes it. Students should not: install or remove software; delete files; change passwords or account information; create or remove user accounts; disable security protections; reveal personal information. Pair Share — 5 minutes Each pair shares its recommendation: Our user wants to __________. The problem is __________. We recommend changing __________ because __________. One tradeoff is __________. We would know the change worked if __________. If time permits, ask students whether another setting could accomplish the same goal with a different tradeoff. Exit Ticket — 3 minutes Present the following situation: A student increases the screen brightness to make the text easier to see, but the device’s battery begins draining quickly. Students respond: What goal did the student accomplish? What tradeoff did the change create? What different setting could improve readability while using less battery? A possible response: Increasing the brightness made the screen easier to see, but it reduced the battery life. The student could increase the text size or contrast instead. Word Bytes (Student-Friendly Examples) Students add “optimize,” “accessibility,” “performance,” and “default setting” to their Word Bytes dictionary with examples. Suggested examples: Optimize – Turning on battery-saver mode so a laptop lasts through a long trip. Accessibility – Increasing the text size so information is easier to read. Performance – Closing unused applications so a device runs more smoothly. Default Setting – The original screen-brightness level selected by the operating system.”
