Transcript Formative Assessment - University of Dayton

Overview


This is a science class in a CD special
education resource room at a lower
income high school.
The classroom contains 11 high school
students, 7 boys and 4 girls, who have
a 1st through 4th grade reading level.
Standards:

Grade 9-Ohio 1- Explain how stars and
other celestial objects provide
information about the processes that
cause changes in composition and
scale of the universe.
Formative Assessment:






Student’s were given a pretest to see what they know
about black holes at the very beginning of the lesson.
The video downloaded from United Streaming was viewed.
Discussion Questions were:
1. Describe how a black hole is formed from the time a
massive star begins its collapse.
2. Describe the steps involved in determining the mass of a
black hole. What do you have to measure or observe in
order to estimate the mass?
3. If you were observing a probe entering the event horizon
of a black hole, you would see it “hovering for an eternity
and destroyed in an instant.” Discuss the meaning of this
phrase as it applies to conditions near a black hole.
4. Discuss Einstein’s theory of gravity and the curvature of
space time.

Project: Divide class into 3 groups of 4, giving each a
different kind of black hole to research. Group one did Stellar
Mass black holes. Group 2 did Super Mass black holes and
group 3 did mini black holes.
They were assessed on the research project using the
following rubrics:
• 3 points: report well-researched, information clearly and
logically organized, presentation interesting and lively
• 2 points: report adequately researched, information
sufficiently organized, presentation dull
• 1 point: report insufficiently researched, information
inadequately organized, presentation poorly prepared
Summative Assessment

Students were given a final test. This
was basically the 1st test they were
given for the summative assessment,
rewritten slightly so that it was more
at their reading level.

4 of the 8 Questions used on
the Pretest and Final Test
One of the Discussion Questions after the Movie




1. Describe how a black hole is formed from the time a
massive star begins its collapse.
We discussed, as we saw in the movie, that first there was
a huge explosion, followed by huge implosion and then an
incredible concentration of mass.
What was previously the size of 10 of our suns is now the
size of Washington D. C. We discussed prior lab with the
sun and showing how many earths we could line across it.
Then we drew the pinpoint on just one of those earths
representing something the size of Washington DC.
An example of an
accommodation for the 1st
question:





1. To detect black
holes, astronomers
look for____.
ultraviolet radiation
they emit
objects falling out of
space-time
nuclear reactions at
their centers
stars circling massive
compact objects

1. To find black holes,
astronomers look for
_______.
Ultraviolet radiation
they spit out
Objects falling out of
space and time
Nuclear reactions at
their centers
Stars circling huge
invisible objects
Overall Reflection

All students had improved their scores much better
than I had anticipated.
Research was hard for the students as they read at
such a low level but they still were able to gather
enough data to do a Venn Diagram which we will
do this week.
Next time I will try to have sites that they may be
able to comprehend better.
I’ll also remember that if the lesson plan states that
it can be done in two 50 minute class periods, that
a special ed group may actually need at least twice
as much time, if not 3 times as much.
