3. Pick one of Ms.
Culbertson's eight points about directions that you found particularly
interesting, and explain why you found it to be interesting. Elaborate as
necessary.
The most interesting point to me was the following: “When
teachers are giving directions, they are not conducting an inquiry lesson.
Efficiently communicated directions in which transition time is minimized do
not normally allow time for students to debate the pros and cons of what is to
be done. Unlike Ms. Bey in Case 3.7, Ms. Culbertson did not open an opportunity
to argue about the selection.”
I think this point is interesting because I have seen many
teachers give unclear directions about an assignment and it significantly elongates
the transition time. If a teacher has not thought through their directions
beforehand to try to find points of confusion and correct them, it is likely
that there will be confusion in the classroom. Even if the teacher responds to
students’ questions and clarifies these points of confusion after giving
directions, it is still more likely that students get sidetracked with their
confusion and don’t listen to the questions, or tune out the discussion because
they think the delivery of directions is over and there are distracted by the
assignment, etc. I have also seen this question/answer time turn into a forum
for students to express their own opinions about the assignment, usually
expressing things they don’t like about it. To avoid this and hopefully ensure
comprehension of directions, it is best to prepare the delivery of directions
beforehand and try to communicate them clearly. It is also a good idea to write
down the important aspects of the directions so that you don’t mistakenly leave
out an important part while you are communicating to your students.
4. Make up a
student reasoning-level question and a student memory-level question.
Then answer each as you would in your classroom. Finally, explain why and
how you did not answer each in the same way.
Reasoning-level question:
Andrea: “I don’t get problem #4 on the homework, is says, “Show
that x(3x – 2 – x + 9) and 2x2
+ 7x are equivalent expressions.”
Ms. Nordin: “This is a
challenging question! Hmm… so if I were to sit down and try to figure this
problem out, I would first need to know what it means for two expressions to be
equivalent. We learned a couple of weeks ago that ‘equivalent expressions’
means expressions that remain equal, or have the same value, when any value is
substituted in for the variable. Okay, that helps give us some direction to
figure this out! So now we know that we need to show that x(3x – 2 – x + 9) and
2x2 +7x are have the same value when any value is substituted in for
x. That doesn’t seem like an obvious fact when we first look at these two
expressions. Oh! How about we start with one of the expression and see if we
can manipulate it to look like the other one. Let’s start with x(3x – 2 – x +
9). Hmm… this expression has parentheses while the other doesn’t, so let’s start
by distributing to get rid of the parentheses. When we distribute we get 3x2
– 2x – x2 + 9x. This is an equivalent expression to the one we
started with because all we did was distribute (Distributive law)! Now looking
at this expression, we can see that there are some like terms, so let’s use the
commutative law to switch the order of the terms, so we get 3x2 – x2
+ 9x – 2x. Now we can just add the like terms, so we have 2x2 + 7x.
This looks exactly the same as the expression from our question! So we have
showed that the two expressions are equivalent.”
Memory-level question:
Andrea: “What does the ‘commutative
law’ mean?”
Ms. Nordin: “The commutative law says that any finite sum or
product remains the same if you reorder its terms. This can be shown
symbolically by a + b = b + a, and ab = ba.”
I answered the reasoning-level question with the think-aloud
strategy. This is beneficial for this type of question because students can see
your thought process and understand how
to do something rather than just what
to do. I answered the second question directly because it was a memory-level
question, so it is appropriate to simply provide the answer.
5. Compare Cases
3.18, 3.19, and 3.20, pointing out what you personally found compelling.
In case 3.18, Mr. Grimes presents the overhead transparency,
asks his students is they can see what the blocks and circles have in common,
and immediately has them answer. While this is an inquiry-learning activity,
and while the discussion that ensues seems like a productive conversation, Mr.
Grimes did not allow time for the whole class to think about an answer before
the discussion began, which probably left many students listening to the
conversation without formulating their own answers (and practicing thinking
critically). The discussion also only involved four students, leaving the rest
of the class potentially disengaged.
Case 3.19 represents, in my opinion, a better example of this
inquiry learning activity. In this case, Mr. Smart presented the same question,
but required that the students all take three minutes to formulate their own
answers before he opened up the discussion. This is more beneficial to the
class because everyone had time to think critically about the question and
engage in the activity. Again, though, in this case only a few students were
involved in the discussion (as far as we know), so it would be impossible for
the teacher to gauge the understanding of each individual.
I personally found Case 3.20 to be the most compelling of all
three cases because the same activity was presented, but in this case Ms.
Cramer had each of her students write their reaction on a tasksheet. This no
only allowed each student time to formulate their own answers, but also gave
them a chance to practice communicating their thought process (an important
skill). The tasksheet method also provided Ms. Cramer with a means to assess
the understanding and progress of each student in her classroom. After everyone
had time to work on their tasksheet, a discussion was still held so that
students could benefit from other ideas in the classroom, and Ms. Cramer could
ensure that the purpose of the activity was conveyed to every student.
6. Which of the
nine points about cooperative-learning sessions do you find most interesting
and why?
The most interesting point to me is the following: “Tasksheets
direct students’ focus and provide them with an overall picture of what they
are expected to accomplish in their groups.” In my experience, I have found
that students stay on task better if they have something to produce, such as a
tasksheet. If they are engaging in a group activity where they don’t have to
write anything down or turn anything in, it seems more vague and less
purposeful. But if the group is collaborating together to create something
together that they will present either to the class or to the teacher, they are
more likely to take ownership over the activity and engage more fully. There is
a delicate balance, though, to how intensive the tasksheet should be. If it is
too thorough, students may become overwhelmed and focus more on getting it done
rather than learning through working through the tasksheet. For this reason,
the tasksheet should be a fairly simple guide through the activity. I also
think the tasksheet should, in general, not receive a grade so that students
are not motivated to just find the answers to fill in to get a good grade, but
can focus on the purpose of the learning activity.

Swap stories with a colleague about mathematics homework assignments that include examples of efficient, productive assignments, as well as examples of useless or counterproductive assignments.
Swap stories with a colleague about mathematics homework assignments that include examples of efficient, productive assignments, as well as examples of useless or counterproductive assignments.
The least beneficial homework assignments I have ever seen are
those that ask students to solve certain math problems where the answer
correlates to a letter, where the purpose is to spell out the answer to some
riddle. Or, similarly, the answers to the math problems correlate to some word
on a crossword puzzle, or something of that sort. In my experience tutoring
students with these kind of tasksheets, students are totally focused on finding
the answer to the riddle or puzzle and don’t pay as much attention to the math
part of the worksheet. It is also my experience that it is possible to solve
the word puzzle without fully engaging in the math, so many times I have seen
students quit solving the math problems halfway through the worksheet, fill in
the remaining letters (because they have solved the riddle), and think they
have successfully completed the assignment. An
example of a productive assignment I have seen dealt with finding the surface
area of three-dimensional objects. The students were asked to find various 3-D
objects from home and discover relationships in processes to find surface area
for different objects. I remember in particular that one of my students was
asked to find a toilet paper roll and measure the surface area using given
formula, and then they were asked to cut the toilet paper roll and discover
that the formula is just the area of the two circles added to the area of a
rectangle. This was an inquiry-based learning activity that they were able to
do from home, that was successful in getting them to discover a relationship
but wasn’t too time-consuming or difficult to accomplish on their own.

Look over a mathematics
textbook currently being used in a middle, junior high, or high school. Select
two topics from different chapters of the text. Examine how each topic is
presented. Categorize aspects of each topic as to whether they originated as a
concept construction, discovery of a relationship, or invention. For example,
here is how I labeled some aspects of two topics from the prealgebra text whose
table of contents appears in Exhibit 1.4.
Topic: Proportional
Relationships
-Constant of
proportionality (unit rate) is a concept construction of a comparison of things
that exist that can be measured. The terms “constant of proportionality” and
“unit rate” are invented conventions.
-Proportional
relationships and comparing two ratios are relationships.
-Comparing two
ratios to find an unknown amount of something, and using cross multiplication
to solve for the unknown are inventions of algorithms.
Topic: Graphing on a Number
Line
-Distance
and direction are concepts that exists in nature.
-The terms
“absolute value”, “direction”, “positive”, and “negative” are invented
conventions.
-The number line is an invention to
illustrate a concept.

Activity #2 pp. 169-170 and post your reactions.
I very much enjoyed reading these two excerpts. Both of these
authors communicated a disconnect between real mathematics and “schoolmath,”
and both argued the importance of educating kids in the art of real
mathematics. The problem is how to do
that. The most obvious way to me to teach students real mathematics is to use
inquiry-based teaching methods that lead students to discover mathematical
concepts. The order of discoveries should also be guided by the teacher in the
natural progression of discovery of mathematical concepts throughout history.
This would present students with an organic encounter of real mathematics.

Transitional Activity 1 p.171
What strategies should
teachers employ to lead their students to construct mathematical concepts for
themselves? How should lessons for construct-a-concept objectives be designed?
What are some strategies for monitoring students’ progress during lessons for
construct-a-concept objectives?
Teachers should employ creative, hands-on activities for their
students to participate in that will lead the students to construct
mathematical concepts for themselves. For example, the activity that our class
did on the first day to work with grid of nails on a wood board and use rubber
bands to find all of the possibly different sizes of squares. This was an
engaging activity that allowed us to discover through experimentation how to
find the different sizes of squares, which solidified our conceptual
understanding.
Lessons for construct-a-concept objectives should be designed
similarly to the example described above. First, students should participate in
an engaging activity that leads to discovery and motivates direct instruction.
Second, the teacher should employ direct instruction, ensuring that each student
understood the concept involved in the hands-on activity and introducing
algorithms.
One strategy for monitoring students’ progress during lessons
for construct-a-concept objectives is to walk around the room while students
are engaging in the discovery activity and listen to discussions or look at
written papers, and guide students who may be struggling. It is also a good
idea, as I talked about earlier in this week’s journal, to have a simple
tasksheet to act as a guide and to give teachers an idea of individuals’
understanding.

Interview with a teacher (Activity 1.4)
Kaitlyn: For how
many years have you been working as a professional mathematics teacher?
Mrs. Lindsay:
This is my fifth year, so I have been at West High for four and half years.
Kaitlyn: How, if
at all, do you teach differently now than you did during your very first year
as a mathematics teacher?
Mrs. Lindsay: I
collaborate a lot more with other teachers than I did when I first started
teaching. This has changed and improved my teaching style quite a bit. I have
also integrated more investigative learning than I did when I started.
Something else I’ve discovered is that projects that students take home take a
huge amount of time to grade and students don’t really get enough out of them for
me to invest that much time in grading them. I would rather spend my time more
efficiently in investigative learning activities in class. I also used to bring
in a lot of guest speakers to my College Prep. Math class to give students a
chance to hear from people working in various professions that are using
mathematics in their careers, but I haven’t done that once this year. It is so
time consuming to plan the speakers, and I just haven’t had the time this year.
Kaitlyn: Do you
feel like you spend less hours working now than you did when you started?
Mrs. Lindsay: A
little bit less... but it’s not that different. I have taught many different
courses each year I’ve been here, so I always have to spend a lot of time
formulating new lesson plans. It’s hard for me to work from home, though, so I
always get it done here.
Kaitlyn: How late
do you usually stay after school to get things done?
Mrs. Lindsay: Well
I used to come in at 6:30 every morning, now I usually come around 7:30. I
generally leave before 5 every day.
Kaitlyn: Reflect
back on that first year and talk about your experiences. What were the major
surprises - both the satisfying ones and the disappointing ones?
Mrs. Lindsay: One
positive surprise that I experienced my first year is that there were actually
quite a few students who worked extremely hard in my class despite their
low-income circumstances and bad family situations. I was expecting these
students to be the most difficult and least driven, but many of them were very
dedicated students. One difficult surprise I experienced was how difficult it
is to manage all of the different classes I teach. It can be really challenging
when you’re teaching a lot of different subjects to create engaging lesson
plans for all of them, and at this school we have red and black days, so I will
often get confused between my classes! Another disappointing surprise was that
there were some students that I just didn’t have the capacity to help. I came
in with the attitude that I would get every students excited about math, and at
least engaged in the material, but I learned that sometimes there’s only so
much you can do to make kids interested.
Kaitlyn: How is
your professional life different today than it was then?
Mrs. Lindsay: My
first couple of years I decided I wouldn’t take part in any extracurricular
activities at all because I’ve heard that it’s really easy to burn out, and I
didn’t want that to happen. Now, though, I participate in more extracurricular
activities; mainly I lead a competing math team. It becomes easier to be
involved once you get to know the administration better and you’ve had a couple
of years of teaching experience.
Kaitlyn: I am in
the process of learning how to be a professional mathematics teacher. What
advice do you have for me at this stage of my career?
Mrs. Lindsay:
This is a hard question because there are so many things that you just can’t
learn until you get thrown into the classroom, but something I would strongly
advise is to absorb everything you
can from your student teaching. While you’re in student teaching, learn how to
deal with discipline and classroom management problems. Then incorporate these
skills that you’ve learned into your own classrooms on the first day. Start the year off right. Your main battle will
be managing the classroom, but once you’ve learned those skills teaching
becomes much easier. Another piece of advice I have for you is to teach them
something everyday. Your first couple of years as a teacher will be immensely
challenging and some days you will probably feel so overwhelmed and unprepared
that you’re not sure what to do, but no matter what state you’re in or how
you’re feeling, just make it a goal to teach them something each day.
Sample Homework: One does not "simplify" inequalities (just as one does not simplify equations or other relations); instead, don't you mean "solve"?
ReplyDeleteSample Quiz: Same issue here.
Looks like your quiz indeed positively reinforces the behavior of completing homework. Yay.
3) I find this point to be interesting too. Some teachers unfortunately think that they are expected to constantly conduct inquiry--not true and disastrous! I agree that "it is best to prepare the delivery of directions beforehand..."
4) Your think-aloud response to the student's reasoning-level questions demonstrates solid understanding of reasoning-level; same with your memory-level response. Note that you may want to respond to this memory-level question with a "how might we find that out?" reply (you know..."teach 'em how to fish).
5) I too prefer Case 3.20.
6) I too am a fan of task sheets as an anchor for focus. You make a very astute point: "If it is too thorough, students may become overwhelmed and focus more on getting it done rather than learning...."
7) I like your feedback regarding students focusing on the end result of a "silly" riddle instead of the mathematics. We should make the mathematics the riddle, right? That's all that math is really is: problem solving.
9) Thanks for your response; we'll be talking a lot more about these things (concept, discovery, invention) in the near future.
10) In addition, I think the curriculum should be adjusted so that it looks more like it used to look 50 years ago (namely, a focus on logic, problem solving, and abstraction...you know, things that real mathematicians focus on (not balancing checkbooks or crunching numbers)).
11) Thanks for getting started on your unit draft. Obviously, we'll be fleshing these out soon.
12) Thanks for your thoughtful reply; again, we'll talk a lot more about these ideas very soon.
13) Oh no! What a bummer. Let me know when you get this completed by shooting me an email at cangelos@math.utah.edu
Thanks!
Amanda,
ReplyDeleteThanks for the feedback, and thanks for pointing out the mistakes on my sample homework and quiz! I will fix them and post another draft right now.

What did you think of the comment "One positive surprise that I experienced my first year is that there were actually quite a few students who worked extremely hard in my class despite their low-income circumstances and bad family situations. I was expecting these students to be the most difficult and least driven, but many of them were very dedicated students."
ReplyDeleteThanks for finishing this up, Kaitlyn. Things that stood out to me include Mrs. Lindsay's feedback regarding the effectiveness of student projects, absorbing as much as possible from your student teaching experience (focusing on classroom management), and that "there's only so much one can do to make kids interested." The third point regarding student motivation is important, because nothing works for all students all the time; this is one reason why it's crucial to constantly "switch it up" (so that you'll hopefully reach everybody at least once...but you'll never reach all students at the same time).
ReplyDeleteEmina,
ReplyDeleteI thought this comment was very interesting. It sort of rubbed me the wrong way because I think it's wrong to stereotype individuals based on your impression of their socioeconomic or racial group. I believe that it is essential to view individuals as individuals when you are a teacher. If you expect students to not be as driven, oftentimes students can sense that you feel this way and will be less motivated to work hard in your class, and outside of your class. It's not okay to project your low expectations onto your students. You can be aware of struggles they may commonly face, but judging their character based on their struggles is a different story. At the same time, it was hard to tell whether this teacher was humbly admitting that she had wrongly felt this way before, or if she had no problem with the biases that she held. Either way, whether she recognized it or not, this mindset is not acceptable in my opinion.
