Wednesday - TinkerPlots

Sampling and Simulation

This morning, we will look at taking samples of fish from a population of normal and genetically engineered fish.  The activity titled Fish-Length Distributions from Key Curriculum Press (2012) will introduce the the Mixer device in the Sampler Engine as a simulation tool.  All of the necessary files are linked below (Google Drive).



Vocabulary:  Sample, Population, Distribution, Mean, Hat Plot, Conclusion, Claim (Hypothesis), Inference, Mixer Device, Sampler Engine, Sample with Replacement, Sample without Replacement, Sample Size, Margin of Error

Monday Afternoon - Classroom Connection

Classroom Connection

Watch an animation created by a researcher from NC State.  What are you noticing about the students' statistical reasoning?



Monday Afternoon - Scrambled Survey

Personal Information Survey Results

Your teacher compiled the responses to the survey in a spreadsheet and then randomized the order of the columns that contained the data for questions. Thus, the columns A, B, C, … N, O, P did not match the order of the questions 1-16 on the survey.  Unfortunately, he/she did this before giving each column a name for the variable that describes the measurement taken from that question.  We need to investigate this data and help the teacher label data with appropriate variable names, rather than using A, B, C…, N, O, P as variable names. In other words, which question on the survey could a set of data have come from?

Your Assignment

You have been assigned to investigate data for two variables. Open the file
containing the mislabeled survey data. For each letter variable name you are asked
to investigate, think about what type of data variable is represented and use graphs
to display the data. What possible questions on the survey could produce this type
of data? You can use any analysis tools available to you in the software and
explore any of the data from variables A-P.
For each letter variable name you were assigned, answer the following questions.
Be prepared to share your answers and evidence with the class.
1. Which survey question(s) could your data match?
2. How do you know? Provide an explanation to convince another classmate.
3. How confident are you in your choice? Explain.
4. In investigating the data for this variable, did you find evidence to support a match of another variable name to any other questions? Which ones? Support your claim.

UG Tech Class - 11Feb15 Tasks

Undergrad Tech Class  --  Wednesday, February 11th

On Friday, you will be learning more about iPads so I decided to share information about two apps that are very popular with educators at ALL levels. A volunteer can display / play the videos for the class.

Task 1: 15 minutes (stop at 20 minutes)
Get the Eno pens to work.  Dr. Jacobi will be there to assist you.  Pull up Google Earth and create a mathematically engaging graphic using at least two tools (Jared).  Showcase a few items (Jensen).

Task 2: 5-10 minutes
Read the Learning and Leading Article and briefly discuss in a small group
Students Explain Everything with iPads

Task 3:  3-5 minutes
Watch the Explain Everything Overview  - It goes pretty fast, but does provide an overview.

Task 4: 5 minutes
Watch the video described below (elementary school example - student video)

I thought you might get a kick out of this "lesson" on the number 18 by one of my kids with his buddy. The kindergartener was in charge of writing on the screen, the older kid was just there as a coach.  This is their first time working on something like this and was meant to be a practice run.  This is what I was referring to in my journal.  I just love the explanations, hearing him verbalize his thought processes and how he is very obvious on checking his thinking.  Many of the videos are similar to this one.  Click here to view this lesson about 18.

Task 5:  5 minutes
Watch this video I created last summer for MATH 360 using Doceri (high school example - teacher video)

Task 6: 5 minutes
Reflect on this class session in your journal.
