Today’s objectives
- Explain what makes something a computing innovation, and how computing innovations are improved through collaboration (LO CRD-1.A)
- Explain how computing innovations are developed by groups of people, using online collaboration tools and models like pair programming (LO CRD-1.B)
- Demonstrate effective interpersonal skills — communication, consensus building, conflict resolution, and negotiation — during collaboration (LO CRD-1.C)
Bell ringer
Your school is replacing the paper lunch line with a lunch-ordering app. Round 1: list every need a user of this app might have. Go for quantity — every kind of user, every situation you can imagine.
Round 2: combine lists with a partner. Count the needs your partner caught that you missed — and the ones only you caught.
01. What Counts as a Computing Innovation
Key Vocabulary (LO CRD-1.A & CRD-1.B)
| Term | Definition (write it) |
|---|---|
| Computing innovation | |
| Pair programming | |
| Bias |
Innovation or Not? Run the Test
For each candidate, apply — is a program an integral part of its function? — then classify it's three shapes.
Complete the empty cells.
| Candidate | Computing innovation? Why / why not | Type |
|---|---|---|
| Self-driving car | Yes — software that steers, brakes, and navigates is integral to its function | Physical computing innovation |
| Picture-editing app | Yes — the innovation IS a program | |
| E-commerce (shopping online) | Nonphysical computing concept | |
| A wooden bookshelf | ||
| Smartwatch that tracks heart rate | Yes — an onboard program collects and analyzes the readings |
Stop and think
- An old vending machine drops a snack using a purely mechanical coin lever. A newer model runs software that tracks stock and accepts phone payments. Apply the test from today: which one is a computing innovation, and why?
- E-commerce is not an object and not an app you can install, yet the College Board calls it a computing innovation. Explain what makes that classification work.
- Invent your own example of each shape — one physical, one software, one concept — that did not appear on today's slides.

02. Why Collaboration Improves Innovations
Why Diverse Teams Build Better Innovations
- Diverse perspectives on a team protect the PRODUCT by .
- Consultation and communication with are important aspects of developing a computing innovation.
- Talking to potential users before building matters because .
Stop and think
- In the bell ringer, your merged list contained needs you missed alone. Connect that experience to today's claim: what does effective collaboration produce that solo work usually cannot?
- A team of expert programmers — all the same age, from the same neighborhood — builds a city transit app that works badly for wheelchair users and night-shift workers. Using the word bias, explain how the team's makeup shaped the product, and state the fix.
- Why does the College Board insist on gathering information from POTENTIAL users — people who don't use the program yet — rather than only its current fans?

03. How Real Teams Collaborate
Group Work vs. True Collaboration
Just dividing the work
True collaboration
- You can tell true collaboration happened because the final product .
- Online tools support collaboration by allowing programmers to on ideas and documents.
- Splitting the work into silos fails as collaboration because .
AP TIP: On the exam, 'collaboration' means perspectives mixing during development. An answer choice that just divides tasks is describing group work, not collaboration.
Watch out — “Collaboration Means Splitting Up the Work”
Myth: A good team divides the project into equal parts, each member builds their part alone, and the pieces get combined at the end — that's what collaborating means.
Explain why this is wrong:
Deep Dive · Beyond the AP Exam
Deep Dive: Collaboration at Internet Scale
The problem
How open source solves it
- A pull request is shared work plus .
- Open-source teams practice interpersonal skills mostly through .
- The AP exam tests what online tools make possible, never .
Deep dive only — the AP exam never asks about brand-name tools; it tests WHAT online tools make possible: sharing and feedback.
Stop and think
- A four-person team 'collaborates' by splitting an app into four files and combining them the night before the deadline. Explain what their final product will fail to reflect, using today's language.
- Two pair-programming setups: in one, the navigator scrolls a phone while the driver types; in the other, the navigator questions every line. Which pair is running the real model, and what is the passive pair losing?
- Your team deadlocks 2–2 on a design choice. Name two interpersonal skills from today you could apply, and describe one concrete move for each.

Common AP Traps
Three ways Topic 1.1 loses points on the exam — one minute now, real points in May.
“It must be a gadget” — in your own words:
“Diversity is only fairness” — in your own words:
Passive pair programming — in your own words:
Collaboration, in One Slide
- A computing innovation includes a program as an integral part of its function — and it can be physical, nonphysical software, or a nonphysical concept.
- Effective collaboration produces an innovation that reflects the team's diversity of talents and perspectives, and diverse perspectives help avoid bias.
- Consultation and communication with users — including potential users — reveal a program's purpose from diverse perspectives and shape its design.
- Online tools support collaboration through sharing AND feedback; pair programming is a common model that facilitates it.
- Effective teams practice interpersonal skills: communication, consensus building, conflict resolution, and negotiation.
Exit check — I can…
- ☐ classify a computing innovation as physical, software, or concept (LO CRD-1.A)
- ☐ explain how diverse perspectives improve a product and help avoid bias (LO CRD-1.A)
- ☐ describe how teams collaborate: online tools and pair programming (LO CRD-1.B)
- ☐ name and use the four interpersonal skills of effective teams (LO CRD-1.C)
