This document provides information about using LEGO Mindstorms robots for STEM education. It includes the following: 1) An overview of the allowed robot parts for competitions, including controllers, motors, sensors and requirements to check competition rules for any changes. 2) A discussion of general thoughts on common problems teams face like aiming robots and heavy attachments, and best practices such as fixtures and gearing. 3) An explanation of computational thinking concepts like decomposition, patterns, and abstraction and how they apply to breaking problems into steps and generalizing solutions in computer science and robotics.
First LEGO League Kickoff - Coding and Confidence
- 1. Discover STEM through Mindstorms: Brick by Brick
- 2. Aaron Maurer
- 3. LEGO Master Educator & Advisor
- 4. Reality is perception: not a reflection of truth
- 7. How many different ways can you use this coffee cup?
- 15. Raise Your Right Hand
- 18. We express who we are through what we make.

- 21. Allowed Robot Parts • Controller (1): EV3, NXT, RCX or SPARK PRIME • Motors (4): any type • As many sensors as you like but only from this set – touch, light, color, rotation, ultrasonic, and gyro • They must all be LEGO-manufactured sensors • Be sure to check this year’s rules for any changes, especially due to SPARK PRIME
- 22. Apple Users: Do Not Update to Catalina https://education.lego.com/en-us/downloads/mindstorms-ev3/software
- 23. 94 Team Scores - Moline and Quad Cities 2018 Regionals
- 24. 94 Team Scores - Moline and Quad Cities 2018 Regionals
- 25. What does it mean? Distribution of high & low table scores Low table scores below 50 ~ 40 teams High table scores above 100 ~ 11 teams What are the skill differences?
- 26. General Thoughts PROBLEMS • Aiming the robot in base • Moves & Turns without finding waypoints • Heavy attachments - tool motor has little control with a massive attachment • Single finger attachments • Team members not knowing what to do next BEST PRACTICES • Fixtures to align robot in base • Plan each mission’s way- points • Gears w/small motor, or use large motor • Fingers to cover error zones • Practice mission changes, watch YouTube
- 30. Computational Thinking Concept Computer Science Application Break a problem into parts or steps Break a computational graph problem into 4 sections, each one to be completed by a different computer processor Recognize and find patterns or trends Visualize data comparing microchip material and computer speed to notice a trend Develop instructions to solve a problem or steps for a task Write a computer program to sort data Generalize patterns and trends into rules, principles or insights Use data structures to more easily and efficiently retrieve and use information in a program
- 31. Patterns
- 32. Patterns Where do we have to lift objects? Where do we have to push? Where do we have to pull? Where do we have to identify color? Where do we have to drop items?
- 33. Decomposition
- 34. Decomposition What are all the possible things that need to be accomplished on the board? What are all the barriers to these tasks? Create subtasks of learning
- 35. Decomposing Complex Problems = CT
- 38. Abstraction
- 39. Abstraction Generalize patterns and trends into rules, principles, or insights *Cleaning up code *My Blocks *Streamlining Mission Structure
- 65. Program Flow
- 66. Wait vs. Sensor
- 68. Move Steering Blocks Mode Steering Speed/Power Number of Rotations Brake or Coast Which motors are controlled
- 69. Wait Blocks Wait For Reflected Light Sensor Compare Value - Comparison Operator - Comparison Value Change Value - Change Direction - Change Amount Light Sensor Port
- 70. Loop Blocks Name of loop This output value provides the count of iterations of the loop
- 71. Switch Blocks – If and Case Statements
- 72. Touch or Black Line Use math on the logic outputs of the Sensor Blocks to produce an OR result that controls the loop.
- 73. Debugging Ideas • If you don’t know where the robot is in the program, use a Sound Block to just play a tone to see if the robot has gotten to a particular point. • What value does my variable have? Display the value to the EV3 screen to see the value. • Take a subtask out of a more complex larger program and debug it separately rather than trying to debug it in the full more complex environment.
- 75. Private Reasoning Time • Take about 1 minute for private reasoning time(solo) • Reflect on morning learning • How can you apply what you have learned to your FLL team? • What new ideas could you use? • What do you plan to learn more about? • What further questions do you have?
- 76. Partner Reasoning Time • Discuss your ideas with a partner/small group: • How can you apply what you have learned to your classroom? • What new ideas could you use? • What do you plan to learn more about? • What further questions do you have?
- 77. Wrap Up
- 78. The scandal of education is that every time you teach something, you deprive a child of the pleasure and benefit of discovery.
- 79. Think about …. • Resilience • Risk taker • Problem solving • Enthusiasm • Confidence • Self belief • Inclusive • Social skills • Empathy • Love of learning How many of these are picked up on high stakes assessment? Or less cynically... What does a classroom look like that promotes these attributes?

Editor's Notes
- #2: Quick introduction of who I am
- #3: Quick introduction of who I am
- #17: You are in your groups. Being is a group is very important to taking your work and learning about yourself and the world around you to a new level. When you can combine forces you can create a superpower that leads to something as amazing as Captain Planet.
- #82: Why is so hard to become a leader? Why do we come up with so many excuses? If we want to be a leader we must see the end before we begin the journey. Dreaming is not hard, leading is hard. The difficult part is not dreaming, but sharing it out loud because at this point it might now work. Nobody has been there to your dream and maybe you don't know either. The difficult work of leadership begins when we announce and share our painting. Describe that future of wha It has been said by Seth “Ask yourself the question, ‘will the work I set out to do be criticized?” If the answer is NO then you need to find something that will in order to produce CHANGE.
- #83: How are you going to create a ruckus? Stand out. Be different.
