Criterion A.
Explaining Phenomena or Designing Solutions
“Lessons work together in a coherent storyline to help
students make sense of phenomena.”
In CE1, students are introduced to “fair tests” and the
concept of forces that are acting on the parachutes. In CE2, students become
more familiar with the engineering design process. In both of these pre-classroom
extensions, students learn about the practices they will be using in the
engineering exploration. I think that the CE2 especially will help students
understand the challenge better when they get to EE1, as it is a very similar
engineering design challenge. In order to make CE1 more relevant to the
engineering exploration at MOXI, the EE1 lesson could incorporate a review of
fair tests and possibly a chart to record their data. This will help students understand
that they need to complete multiple tests that are consistent with each other
in order to get accurate data and show whether or not their pennyship design is
successful.
“Students get direct experience with a problem or phenomenon
that is relevant to them and is developmentally appropriate.”
In my experience facilitating EE1, during the discussion
about the picture of the fire with a large plume of smoke, many students will
bring up the Thomas fire or other fires that have occurred in our region. This
makes the problem that is being solved in the activity more relevant to the
students. However, I think that one issue with this is that it is sometimes difficult
for the students to make the jump from solving the issue of fighting fires to
solving the issue of creating a device that will hold a sensor that will give
us information about the fire. This problem usually has to be explained to the
students as they cannot make this jump on their own. It might be helpful to
find some video that specifically refers to this issue of firefighters using
information from the smoke plume in order to predict the fire’ behavior. This
would make the problem more realistic and relevant to the students so that they
can focus on the issue of creating a device that will hover inside the wind
columns.
Criterion E. Student
Ideas
“Students have opportunities to share ideas and feedback
with each other directly”
EE1 provides many opportunities for students to share their ideas
with the teacher asking questions and students raising their hands and sharing
with the class. One challenge with this method is that sometimes it causes only
a few students to be answering questions, and keeping shyer students from
sharing their ideas. This can be prevented by providing more opportunities for
students to have ~1 minute discussions with a partner, so that everyone can
have a chance to communicate their ideas.
“Student artifacts include elaborations of reasoning behind
their answers, and show how students’ thinking has changed over time.”
In the worksheet for CE1, students are asked to predict
which sized parachute will fall the slowest. For older groups (grades 3+), it
may be helpful to have a space for students to write down their reasoning for
why they predicted the way that they did. This will allow students to take time
to think through why they chose that answer before the teacher opens up the
class discussion of predictions.
