In Nadia’s case
14, Martha looked at the triangles that she and thought that when you cut
it in half you only came up with two angles so there could only be two angles
in the triangle. Also, she could have not been looking at the fact
at where the lines meet on the triangle in the three different places is where
an angle is actually formed. Alana was explaining an angle by the
slant of a line. She understood that lines needed to work at a slant
somewhat in order to actually form an angle but she was not completely grasping
the concept behind an angle.
In Lucy’s case
15 (line 251), Ron suggests that a certain angle “can be both less than 90˚ and
more than 90˚": Ron was explaining how angles can be both 90 degrees
or over 90 degrees but when he explained it as a “certain angle” can be both
less than or greater than 90 degrees that is where he was incorrect. He
understood you can have angles over and under 90 degrees but did not explain
how that changes the name of them.
In Delores' case 13: the
students wrote their different ideas of what the angles were:
Chad: explained small and large angles in the
terms of long and short. He understood that there were different types of
angles that varied in size but I would want for him to actually know the names
of the angles as well as a way to actually show them versus the way he
explained them.
Cindy: explained angles in a different way to
me. The term slanted was one that was okay with me because when looking
at angles they are slanted. I did not so much like the comment about angles
going down. I feel like angles can be formed in moving in either
direction. I would want Cindy to be able to better clarify what she meant
when describing angles.
Nancy: I like the way Nancy described angles
because she used the actual terms that go along with angles. She was able to explain that little angles are acute angles and
obtuse angles are larger angles. The only thing I would want Nancy to
further explain would be what makes an acute and obtuse angle.
Crissy: did a great job at explaining angles to
me. She had the names as well as the definitions about what angles truly
were. The only thing that she could have done different was to draw a
picture.
Chelsea: I like how Chelsea included pictures
and explained right angles. The thing I wish she had done different was
to draw all kinds of angles.
In Sandra’s Case 16: Casey
says of the pattern blocks, “They all look the same to me.", Casey
believes at first that there is only one kind of angle and that is a 90 degree
angle. As he continues to work with his teacher on the angles he
realizes that there are actually other types of angles that are within shapes.
I found the Angle's video to be very interesting in listening to the students different explanations of what the believed an angle to actually be. I liked watching the one little girl draw the pictures when describing her angles and I also liked how she gave the description's of what she was talking about as she was drawing. The students in this video for the most part to me seemed to really understand angles and I feel like were more advanced when discussing angles than the students that were in the case studies. In my classroom I want to allow students to draw images along with giving me an explanation. Seeing the students give me a visual helps me to better understand if they are grasping the concepts or not.
Annenberg Angles Module:
The usage of the straw as a protractor in part A was very neat to me. I had never thought about using a straw before but not I would consider using them in my own classroom because it is a cheaper as well as more flexible device that an actual protractor. I understand it does not give exact measurements but it still gives a general idea. Using the straw during session A was a neat way to understand the angles.
In part B I did not have much trouble in answering the questions because angles were always something I enjoyed learning about in school and was pretty good at identifying without actual measurements. I did have to freshen myself up on a few terms such as vortex but once I got all of my definition's in order I was able to figure out the problems.
In part C I found the Geo-Logo activity to be fun once I figured out how to do my commands. I could see students actually enjoying that part of the module because students like interactive computer things and I feel like they also learn better that way.

I also think that Martha was only thinking about splitting the triangle in half when she thought there was only two angles. She was not thinking about the third angle that was formed. when the two sets of angles met. If a student in your class did this, how would you correct it?
ReplyDeleteI also thought the students in the video had a good grasp on angles. They were able to explain what they meant in detail when asked. I also liked the picture and explanation the girl gave while she was drawing the shape. I think drawing what students are talking about helps both the student explain as well as you and other students understand what the student is talking about. What do you think?
I liked using the straw too. I did not really think about using one until completing this activity. I would also use it in my classroom. How would you generalize using the straw to using a protractor for angles? Students will eventually have to switch over.
I also never really had a problem with angles in school. How would you help struggling students in your class who are having trouble with angles. For example, what if they cannot learn the vocabulary or confuse the different types of angles?
Happy Thanksgiving!
