The teacher began the chromatography lesson by identifying the key concepts and activating students' prior knowledge. They arranged the information so patterns could be found while explaining the experiment components. The teacher then guided students to the objectives, promoting social interactions and allowing schema construction. Questions were asked to ensure understanding of the process. Suggestions were made for the teacher to get more participation, such as providing a list for students to follow or asking more questions. In the end, it was agreed that the activity engaged students and created healthy interactions.
1. We began in the
Science Center with
Dr. O’Connor
2. We then moved to the
“Authentic” building in
the South West corner
Where Tamara (the
documenter) and Sandra
and Christina
(participants) met and
discussed…
3.
4. Tamara and Sandra were not
able to view the movie, but
Christina, who had voice
issues in the beginning, could
play it on her end.
How do we fix it? We
have no idea…
5. We began with
question number
one:
What scaffolding does the teacher do to present the
chromatography?
Last, he guided the
students to the
objectives,
Then he arranged promoting social
interactions and “Why
the information so don’t we
patterns could be allowing them to
all do it at
found while he advance schema
once…”
“These are actual explained the construction
chromatography components of the
papers” First: He Identified
experiment
the concepts,
activating the “These are the
student’s prior suspects, let’s
knowledge start with the
crime scene…”
6. How about a lap top with
some real-world
Chromatography playing on
YouTube?
Hold on! Wouldn’t
some examples be
helpful here?
Or even a handout
with some
explanations.
7. What other questions might
you ask to ensure that students
are understanding the process?
8. What do these
colors we see
actually
Why is it represent?
important that the
paper not touch
the sides of the
beaker?
Every student benefits from
identifying the objective
9. What suggestions might you make to
the teacher to get more participation
from the students?
“High five!”
“Which one
do you want
to talk
about?”
10. The approach
was very good!
The objectives
were clear and
they produced an
outcome.
Presenting to the judges was a
great way to show
cooperation and
understanding!
11. Maybe if they had a list
to follow it would have
been easier for
everyone to
participate?
But wait a minute,
couldn’t the teacher have
asked more questions to
get everyone involved?
12. At the end of the day we all
agreed that this was a
fantastic, well thought out
activity that engaged the
students and created
healthy interactions
between them!
Case Closed!
