About This Topic

Automation and the future of work explore the profound shift in the labor market caused by robotics and AI. For 12th graders, this topic is highly personal as they prepare to enter the workforce. Students analyze which industries are most susceptible to automation, from manufacturing to white-collar jobs like accounting, and research the new career paths that are emerging in their place. They also examine the economic theories behind automation, such as the 'lump of labor' fallacy.

This unit encourages students to think critically about the social safety nets required for a changing economy, such as Universal Basic Income or lifelong retraining programs. This aligns with CSTA standards for evaluating how computing technologies change the way people live and work. Students grasp this concept faster through structured discussion and peer explanation of how technology has historically transformed work, from the Industrial Revolution to the present day.

Key Questions

1. What responsibilities do developers have to create software that works for people with disabilities?
2. Critique existing software interfaces for their adherence to universal design principles.
3. Design an accessible feature for a common application, justifying its implementation choices.

Learning Objectives

• Analyze existing software interfaces to identify specific features that adhere to or violate universal design principles.
• Evaluate the accessibility of a given software application based on established guidelines, such as WCAG.
• Design a new feature or modification for a common application that enhances its accessibility for users with specific disabilities.
• Justify design choices for an accessible feature by referencing principles of universal design and user needs.

Before You Start

Introduction to User Interface (UI) and User Experience (UX) Design

Why: Students need a foundational understanding of how users interact with software to evaluate and design interfaces.

Ethical Considerations in Technology

Why: This topic builds on an understanding of the broader societal impacts and ethical responsibilities associated with technological development.

Key Vocabulary

Universal Design	The design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design.
Accessibility	The practice of ensuring that digital products and services are usable by people with disabilities, allowing them to perceive, understand, navigate, and interact with the web and technology.
WCAG	Web Content Accessibility Guidelines, a set of recommendations for making web content more accessible, developed by the W3C.
Assistive Technology	Any product, equipment, or system that is used by a person with a disability to increase, maintain, or improve their capabilities.

Watch Out for These Misconceptions

Common Misconception

Automation only affects blue-collar, manual labor jobs.

What to Teach Instead

Explain that AI is increasingly capable of performing 'cognitive' tasks like legal research and data analysis. Use a peer-teaching moment to show how 'Generative AI' is now impacting creative fields like graphic design and writing.

Common Misconception

Automation will lead to the end of all work.

What to Teach Instead

Clarify that while some jobs disappear, new ones are created (e.g., prompt engineers, drone pilots). A hands-on activity looking at 'jobs that didn't exist 20 years ago' helps students see the dynamic nature of the economy.

Active Learning Ideas

Inquiry Circle: The Automation Risk Audit

Groups are assigned different professions (e.g., truck driver, surgeon, artist). They must research the specific tasks of that job and determine which are 'automatable' and which require 'human-centric' skills like empathy or complex problem-solving, creating a 'risk score' for each career.

Formal Debate: The Robot Tax

Students debate a proposal to tax companies that replace human workers with robots, with the funds going toward job retraining. They must consider the perspectives of the business owner, the displaced worker, and the consumer who wants cheaper goods.

40 min·Whole Class

Think-Pair-Share: Skills of the Future

Pairs of students brainstorm three skills they believe will be 'future-proof' against AI. They then swap with another pair and try to 'automate' those skills using current or near-future technology, leading to a class-wide discussion on the unique value of human creativity.

Real-World Connections

• Web developers at companies like Google and Microsoft are responsible for ensuring their products, such as Google Maps or Microsoft Word, meet accessibility standards so that users with visual impairments can navigate and utilize them effectively.
• UX designers at gaming companies like Nintendo consider accessibility when developing new consoles and games, incorporating features like customizable controls and colorblind modes to broaden their player base.
• Government agencies, such as the Department of Transportation, must ensure their public-facing websites and digital services are accessible to all citizens, including those with disabilities, in compliance with Section 508 of the Rehabilitation Act.

Assessment Ideas

Quick Check

Present students with screenshots of two different software interfaces. Ask them to identify one element in each that demonstrates universal design and one element that could be improved for accessibility, explaining their reasoning.

Discussion Prompt

Facilitate a class discussion using the prompt: 'Imagine you are a developer for a popular social media app. What are two specific features you would prioritize for accessibility, and why are these crucial for users with disabilities?'

Peer Assessment

Students share a brief proposal for an accessible feature they designed. Partners review the proposal, checking if the proposed feature directly addresses a specific accessibility need and if the justification is clear. Partners provide one piece of constructive feedback.

Frequently Asked Questions

How can active learning help students understand the future of work?

The future of work can feel scary and uncertain. Active learning strategies, like 'career path simulations' or 'policy debates,' give students a sense of agency. By researching and debating the economic and social impacts themselves, they move from being passive observers of change to informed participants who can plan their own education and career strategies accordingly.

What is 'Universal Basic Income' (UBI)?

UBI is a government program where every citizen receives a set amount of money regularly, regardless of their employment status. It is often proposed as a solution to the job losses caused by mass automation.

Which skills are hardest for AI to replicate?

Skills involving high-level emotional intelligence, complex ethical decision-making, physical dexterity in unpredictable environments, and truly original creative synthesis are currently the hardest for AI to master.

How has automation changed the US economy in the past?

Historically, automation (like the assembly line or the tractor) has moved workers from one sector to another, for example, from farming to manufacturing, and then from manufacturing to the service and tech industries.
