The Evolution of Technology

Active learning works well for this topic because young students need concrete experiences to grasp abstract ideas like accessibility. When they physically simulate challenges and analyze real apps, they connect empathy to design in a tangible way, making the concept stick.

Learning Objectives

1. Analyze the changes in a chosen technology (e.g., telephone, computer) from its invention to the present day.
2. Explain the societal or practical reasons that drove specific advancements in a technology's evolution.
3. Predict plausible future developments for a current technology based on observed trends.
4. Compare and contrast the features and functions of early versions of a technology with its modern counterparts.

Simulation Game

⏱ 40 min·Individual

Simulation Game: The Empathy Challenge

Students try to perform a simple digital task (like finding a website) using only one hand, or with their screen brightness turned all the way down. They then discuss what features would have made the task easier.

Prepare & details

Analyze the progression of a specific technology over time (e.g., phones, computers).

Facilitation Tip: During the Empathy Challenge, ask students to reflect out loud after each simulation round about how the physical limitations changed their experience of the task.

Setup: Flexible space for group stations

Materials: Role cards with goals/resources, Game currency or tokens, Round tracker

Inquiry Circle

⏱ 45 min·Small Groups

Inquiry Circle: App Audit

In small groups, students look at a popular educational app and identify three features that make it easy to use (e.g., big buttons, clear icons, voice instructions) and one thing that could be improved.

Prepare & details

Justify why certain technological advancements were necessary.

Facilitation Tip: When running the App Audit, model how to identify at least one inclusive feature and one barrier in a shared example before letting groups work independently.

Setup: Groups at tables with access to source materials

Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template

Think-Pair-Share

⏱ 30 min·Pairs

Think-Pair-Share: Designing a Better Remote

Students think of how to redesign a TV remote for someone who is blind. They share their ideas with a partner, focusing on textures, shapes, and sounds, before presenting to the class.

Prepare & details

Predict how a current technology might evolve in the future.

Facilitation Tip: For the Designing a Better Remote activity, circulate and listen for students using inclusive language like 'easier to see' or 'works for my friend who uses a wheelchair' in their explanations.

Setup: Standard classroom seating; students turn to a neighbor

Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs

Teaching This Topic

Start by normalizing difference—frame inclusive design as a natural part of making things better for everyone, not as an extra task. Use familiar examples like subtitles or larger font sizes to build prior knowledge. Keep discussions concrete by grounding them in the students’ own technology use, and avoid abstract lectures about disability rights or legal requirements at this age.

What to Expect

Successful learning looks like students recognizing that technology design affects real people’s lives and can articulate simple, actionable ways to make designs inclusive. They should demonstrate this through explanations, justifications, and creative problem-solving in group work.

Watch Out for These Misconceptions

Common Misconception

During the Empathy Challenge, watch for students who say accessibility only matters for a few people. Redirect by asking them to share examples from their own lives where captions or high-contrast screens have helped them in noisy or bright environments.

What to Teach Instead

Use the Empathy Challenge to highlight that temporary situations, like a broken arm or a loud café, can make any technology less usable for anyone. After simulating vision impairment, ask students to name a technology they’ve used recently that would have been harder without sight.

Common Misconception

During the App Audit, watch for students who assume accessibility requires expensive or complex changes. Redirect by having them compare two versions of the same app, one with clear fonts and one with fancy scripts, and ask which one is easier to read and why.

What to Teach Instead

After the audit, bring the class back together to list simple design choices they saw in real apps, like large buttons or color contrast, to reinforce that accessibility starts with basic decisions.

Assessment Ideas

Quick Check

After the Empathy Challenge, provide images of three versions of a device (e.g., a phone from 1990, 2010, and 2020). Ask students to arrange them in order and write one sentence explaining how the newest version addresses needs that the oldest one didn’t.

Discussion Prompt

During the App Audit, pose the question: 'What problem do you think people needed solved that led to the creation of this app feature?' Facilitate a discussion where students justify their ideas based on the barriers they identified in their audit.

Exit Ticket

After the Designing a Better Remote activity, ask students to name one technology they use daily. Then, have them write one sentence about how this technology might change in 20 years to meet more people’s needs, using what they learned about inclusive design.

Extensions & Scaffolding

• Challenge: Ask students to redesign a classroom object (like a ruler or scissors) to be more accessible, then present their design to the class.
• Scaffolding: Provide sentence starters for the Think-Pair-Share, such as 'One problem with the remote is... One way to fix it is...'
• Deeper exploration: Invite a guest speaker who uses assistive technology to explain how inclusive design impacts their daily life.

Key Vocabulary

Innovation	A new method, idea, or product that is an improvement on something that already exists.
Obsolescence	The state of becoming obsolete, meaning no longer produced or used, or out of date.
Advancement	The progress or development of something, especially in technology or science.
Iteration	A repetition of a process or utterance; in technology, it often refers to a new version or update.
