1. Data Collection and Problem Solving – Day 2 Exploring Computer Science – Lesson 2-1

2. Solving Community Problems  According to a Northwestern University study a higher proportion of black (22.6%) and Hispanic/Latino (22.4%) Chicago high school students were overweight, compared with white students (11.8%).  CPS wants to understand why this is true and what can they do to help the situation.

3. Solving Community Problems  At your tables: 1.How would you approach the problem? 2.What kind of data would you need to collect? 3.How would you collect and analyze the data?  According to a Northwestern University study a higher proportion of black (22.6%) and Hispanic/Latino (22.4%) Chicago high school students were overweight, compared with white students (11.8%).  CPS wants to understand why this is true and what can they do to help the situation.

4. Making a Case -vs- Discovery  Making a case (advocacy)—Use data to document situations that contribute to make a positive or negative case for something. (e.g., Let the CTA know about timing of trains and buses; tell the principal about something that needs to be done at the school; tell someone about something you’d like to see continued).  Discovery—Collect data to document situations and then use the data to learn something. (e.g., could your food choices be improved?; do I always take an efficient route to activities?)

5. Research Questions As a group, answer these questions and turn them in…  What is your research question?  What data would you choose to collect to research your question?  What are the limits of this data?  What can you confidently say based on your data?  What perspectives are left out based on your data?

6. Assignment – This will be used for the Unit 2 Final Project. You must have this data!  Every day for the next 2 weeks collect data related to where you go after school—location, means of transportation (walk, bike, etc.), how long it takes to get from one location to the next, any other data that you think would be interesting.

7. Journal Entry  What are the steps you use to solve a problem?
