1. What is the primary defining characteristic of a MicroSim?

  1. It requires specialized software installation
  2. It is a small, focused simulation targeting a single learning objective
  3. It uses complex multi-system modeling
  4. It runs only on high-end computers
Show Answer

The correct answer is B. A MicroSim (Micro Simulation) is a small, focused, interactive web-based simulation designed to help learners understand a specific concept. Unlike comprehensive simulation software, MicroSims embrace purposeful simplicity by targeting one learning objective at a time.

2. Why is simplicity considered a "superpower" for MicroSims?

  1. It makes simulations look less professional
  2. It limits what students can learn
  3. It reduces cognitive load and allows focus on a single concept
  4. It prevents AI from generating them
Show Answer

The correct answer is C. Simplicity reduces cognitive load so students focus entirely on the concept, not on learning a complex interface. Simple structures are also easier for AI to generate correctly, easier to maintain, and more accessible across devices.

Concept Tested: Simplicity

3. What makes MicroSims "AI-driven"?

  1. AI controls the simulation while it runs
  2. Students must use AI to interact with the simulation
  3. Generative AI can rapidly create and modify MicroSim code
  4. MicroSims train AI models for education
Show Answer

The correct answer is C. MicroSims are AI-driven in their creation, not operation. Generative AI tools like ChatGPT and Claude can produce working MicroSim code from educator descriptions in minutes rather than weeks, transforming the role from programmer to designer.

4. In JavaScript, what is a variable?

  1. A function that draws graphics
  2. A named container that stores values
  3. A loop that repeats actions
  4. A method to create buttons
Show Answer

The correct answer is B. Variables are named containers that store values your program needs to remember and manipulate. In MicroSims, variables track everything from canvas dimensions to simulation parameters to animation states.

5. What is the purpose of control flow in programming?

  1. To store data in memory
  2. To decide which code executes under different conditions
  3. To create visual graphics on screen
  4. To organize code into reusable blocks
Show Answer

The correct answer is B. Control flow refers to how your program decides which code to execute under different conditions. Using if/else statements, programs can respond to changing conditions like detecting wall collisions or responding to button presses.

6. Why does embedding MicroSims using iframes transform educational content delivery?

  1. It requires students to download additional software
  2. It limits access to only certain institutions
  3. It enables direct integration within course materials at zero marginal cost
  4. It creates licensing fees for educators
Show Answer

The correct answer is C. Embedding via iframes allows educators to place MicroSims directly within their course materials—textbooks, LMS pages, and websites—without requiring external links or downloads. Once a quality MicroSim exists, any educator can use it with a single line of code at no cost.

7. What role does the draw() function serve in a p5.js MicroSim?

  1. It runs once when the program starts
  2. It creates the canvas element
  3. It runs repeatedly (~60 times per second) to create animation
  4. It handles only button click events
Show Answer

The correct answer is C. The draw() function runs repeatedly, approximately 60 times per second, creating the animation effect. This implicit loop updates positions, redraws graphics, and responds to changing parameter values continuously.

8. Research shows interactive simulations with prediction produce approximately what level of knowledge retention after one week?

  1. 15%
  2. 45%
  3. 75%
  4. 90%
Show Answer

The correct answer is D. According to learning research, interactive simulations with prediction achieve approximately 90% knowledge retention after one week. Asking students to predict before manipulating dramatically increases retention compared to passive methods like reading (15%) or watching videos (25%).

9. A MicroSim ball passes through the right wall instead of bouncing. Which debugging step should you perform first?

  1. Immediately rewrite the entire physics function
  2. Ask AI to generate completely new code
  3. Reproduce and isolate the problem by testing boundary values
  4. Delete the file and start over
Show Answer

The correct answer is C. Effective debugging follows a systematic process: first reproduce the problem reliably, then isolate the cause by narrowing down which code is responsible. Commenting out sections and testing specific values helps identify whether it's a boundary calculation or comparison operator issue.

10. Which code pattern correctly uses a loop to draw multiple circles?

  1. if (i < 5) { circle(i * 30, 100, 20); }
  2. for (let i = 0; i < 5; i++) { circle(i * 30, 100, 20); }
  3. let i = circle(30, 100, 20);
  4. function circle5() { draw(); }
Show Answer

The correct answer is B. A for loop with a counter variable (let i = 0; i < 5; i++) executes code repeatedly a known number of times. This pattern draws 5 circles at different x positions by multiplying the loop counter by the spacing.

11. A teacher wants to demonstrate how changing pendulum length affects swing period. What advantage does a MicroSim offer over the formula \(T = 2\pi\sqrt{L/g}\)?

  1. MicroSims are more mathematically accurate
  2. Students can manipulate the length and observe results directly
  3. The formula is incorrect
  4. MicroSims require no internet connection
Show Answer

The correct answer is B. While the formula provides abstract mathematical truth, a MicroSim enables interactive learning where students drag a slider to change length and watch the swing change in real-time. This direct manipulation creates neural pathways that reading formulas alone cannot build, leading to intuition about how the system behaves.

12. How do web-based simulations promote educational equity?

  1. They require expensive software licenses
  2. They work only in well-funded schools
  3. They run on any device with a modern browser, regardless of location
  4. They need the latest operating systems
Show Answer

The correct answer is C. Web-based simulations liberate education from installation, compatibility, and licensing concerns. A student can access a MicroSim on a school computer in Toronto, a smartphone in rural Kenya, or an aging laptop in Argentina. If it has a modern browser, it works—making quality interactive learning available regardless of resources.
