NO EASY TASK!

Forget the purpose

decision making ?

What decisions learners make in the development of their own investigations?

Question #1

How do learners come to make such decisions?

Question #2

What aspects of the learning environment support these choices?

Question #3

Methods

Yin’s (2003) comparative case studies

Context: A one week implementation of KC with learners between the ages of 9 to 13.

Lisa & “ Togo ” Cakes

Denise

& Red Cakes

Lily,

Velvet

, and Meg

Choice Day Synopsis

“Togo” cakes – Pancakes with syrup in the middle

Engineering tasks: Enough fluffiness and how to get the syrup in the middle of the syrup

Q1: What decisions were made?

Decision #1: Chose to use baking powder as a leavener and determined the amount to use with an experiment.

Decision #2: Chose to freeze different syrups to as the way to insert the liquid into the middle

Q2: How were the decisions made?

Decision #1: Looked for heights of the foam generated from specific quantities of baking powder, water, and time in the microwave

Q2: How were the decisions made?

Decision #2: She developed an experiment to test out whether honey, corn syrup or maple syrup would freeze well enough to be inserted into the middle.

Q3: What aspects of KC helped?

Choice Day Synopsis

Red velvet cake – Denise wanted to make this because her aunt made this style of cake.

Denise initially did not think of this as a science investigation; she just wanted to make the cake.

Q1: What decisions were made?

Decision #1: Comparison cake and a regular cake.

Decision #2: The regular cake uses one egg and baking soda + vinegar.

The comparison cake uses two eggs and baking powder.

Q2: How were the decisions made?

Decision #1: The adult facilitators worked with the girls to figure out what their goals were for the cake.

Q2: How were the decisions made?

Decision #2: The girls wanted a “cakey” and “moist” cake.

Learners and Choice

Science is not just about the content knowledge and the

social practices.

Learners may need a sense that making

informed decisions matter.

We attempted to use the four aspects of KC to explore the notion

that learners can make viable decisions.
