As an introduction to the Modeling Your World workshop, Bob1 began by explaining the meaning of SUCCEED. He challenged the students by asking questions such as the meaning of SUCCEED, and what scientists spend most of their time doing. He explained that science was began by the process of observation. He explained that a flow chart could be made, with observation requiring thought, which requires the act of studying, which requires the development of a hypothesis. He challenged the students further by asking the definition of a hypothesis. "An educated guess," many students said. "Then why don't they just say an educated guess? Why do they say hypothesis instead of a simpler term. You all say that it's a guess. Why can't they just term hypothesis as an educated guess?" Bob1 challenged the students yet once again. When none of the students answered, Bob1 gave them a brief understanding of the word hypothesis. "Scientists like to use big words to confuse others," he said. "That's as complicated as it gets. So, these words are just used to indicate a simpler name. It's nothing to get mixed up about." Then Bob1 introduced modeling, the topic for the workshop, through rope tricks. He showed some knots, but also to acknowledge how a rope is like life. It has a beginning and an end, with complicated weaving in the middle, representing the complications in life. The students seemed to enjoy seeing and trying the different rope tricks. At the end of the introduction, he told students that with the use of computers, observations are more efficient. After break, students began modeling on the computer by learning how to use Stella Research® software. With Cornelia carefully showing them the way, they created a visual model of a disease epidemic in a school of 1000 students. Cornelia explained the different tools used in Stella®, including the stock, flow, converter, and connector. She reviewed the x and y axes so that they could generate graphs displaying the information contained within the model. In the end they completed a model of the disease epidemic and seemed proud of their results. Last Update: |
