This past weekend I had the pleasure of attending the annual CMC North, Asilomar Math Conference. I have attended this conference before, but this was the first year that I was going to be a presenter at the conference. The title of my presentation was "Embedding Authentic Modeling Problems in MS/HS Curriculum" and we featured two of Dan Meyer's 3-Act Video problems (http://blog.mrmeyer.com). The audience had a choice to work on one of the two problems that we included and it seemed to go very well. I've included the presentation below. Please enjoy!

### Re-Engagment Lesson

This lesson actually took place at the beginning of the year, but I am just getting around to it now...

The directions for the third page, “Between vs. Midpoint”, were to first read the student explanation, and secondly write a question or a comment that could make the argument better.

Finally, students worked on a page
of sample work called, “Angle Bisectors”, which asked them to a. look at the
student work and make sense of it, b. if the work was correct, state why, and c.
if the work was not correct, determine where the student made their mistake and
explain why it’s incorrect.

As you can see, what was required of each student was a little different from page to page. I did not want them to do the same thing for all, partly because the four pages dealt with four different mathematical ideas that I wanted to showcase. My purpose was for them to become re-introduced to the problems from the test, and to use a critical eye to determine how they might make each piece of work better if it was incorrect, or expand their knowledge if it was an unfamiliar approach.

Through
the last eight years that I have been a classroom teacher, one common thread
that stands out to me is the amount of professional development that I have
participated in. I have learned about
everything from strategies to engage English Language Learners, to how to
incorporate technology into my classroom, to how to mentor a first-year beginning
teacher. With all of the different
themes and directions that my professional growth has taken on, none of them
have been as meaningful to me as those centered on Common Core and the
Standards for Mathematical Practices.

When I was asked to participate in
the CPEC grant, I honestly had no idea what to expect, nor did I really know
anyone who was involved. I was anxious
and excited and could not wait to see what was happening in my region with
regards to Common Core. The impact that
this two-year grant has had on my teaching practice is invaluable and perhaps
even immeasurable. I continue to take
risks and try new things in my classroom, as well as persevere when I am not
successful the first or second, or even third time. One of my favorite risks that I have taken
recently was a re-engagement lesson in my Geometry classes.

I have found in my eight years of
teaching that the first chapter test is often the hardest for students. I’m not sure if this has more to do with
brushing off the dust from summer vacation, or the fact that Geometry is quite
different than Algebra. Nevertheless, my
current Geometry students played into my theory and were not overly successful
on their Chapter One test. There were
errors in notation, reasoning, and even setting up a correct equation to model
a Geometric principle; all of which are areas that need to be addressed and
remedied in order for a student to be successful in later chapters.

After grading the Chapter One tests,
it was obvious that I was faced with the age-old problem of the “haves” and the
“have-nots” in the sense that some students "have" the understanding and others don't. There was a large
population of students who were struggling with basic concepts on the test, but
there was a considerable amount of them who were successful and were ready to
move on to new applications and ideas.
So, as their teacher, what do I do?
Do I move on and hope that the “have-nots” will catch on
eventually? Or do I start over and cause
boredom and frustration amongst the “haves”?
My solution was to try a re-engagement lesson.

I chose four areas/questions that I
wanted my students to focus on. The
first three questions on the test related to Geometric notation and basic
concepts such as where two planes intersect (many said a point). The second area of concern for me was on an
error-analysis question. The majority of
students were able to articulate which student in the scenario was correct
and/or incorrect, however their explanations and justifications were weak and
unconvincing. The third and forth questions
that I chose for my re-engagement both had Algebraic applications that stemmed
from Geometry. First, an Angle
Addition Postulate problem that involved four adjacent angles (two of which
were congruent) that formed a straight angle, and asked to find the value of
the variable. Second, an angle
bisector scenario where students were given the measure of one of the smaller
angles and the larger angle, both in the forms of an Algebraic expression, and
asked to find the measure of the smaller angle.

My current class schedule is laid
out such that I teach three, 90-minute periods of Geometry every day. Every other day I see the same group of
students, so I see six periods over the span of two days. The way that this particular test panned out
was that I graded my first three classes during the first night and then graded
my second set the next night. However,
once I graded the first set of tests, I was familiar with common errors and
misconceptions, so I did not grade my second set of tests right away. Instead, I went to the photocopy machine and
made copies of student work from the second set of tests. This allowed me to copy student work that was
ungraded, so the students were unaware of the accuracy of the responses. I selected student work that represented the
common errors as well as a few correct solutions, some using a non-traditional
approach.

The next time that I saw each group
of students, this was also the day after their test, I told them that they
would get their tests back at the end of the period, but they had some work to
do first. I knew that if they received
their tests first, they would not buy in to the re-engagement activity. On the white board I had written prompts that
corresponded with each page of student work – there were four pages in total.

For the first page, titled “Notation”, students were asked to find the error in each student’s notation and make appropriate corrections. Because I photocopied the first three questions from the test and used that for each anonymous student representative, there were some pieces of each student work that were possibly correct. If that was the case, students did not need to comment.

The second page was called “True
Statements About Angles” and required students to a. make sense of the student
work sample, b. determine if the work was correct, c. if the student was
correct, they needed to describe the approach, and d. if the work was
incorrect, explain why.

The directions for the third page, “Between vs. Midpoint”, were to first read the student explanation, and secondly write a question or a comment that could make the argument better.

As you can see, what was required of each student was a little different from page to page. I did not want them to do the same thing for all, partly because the four pages dealt with four different mathematical ideas that I wanted to showcase. My purpose was for them to become re-introduced to the problems from the test, and to use a critical eye to determine how they might make each piece of work better if it was incorrect, or expand their knowledge if it was an unfamiliar approach.

As students began to engage in this
activity, I was blown away by their interest and motivation to make sense of
the mathematics. Without asking them to
do so, they started taking out their notes to use as a reference, they were
communicating with their partner to see what they thought, and there were very
few questions of me. This was the polar
opposite of what I normally see in my classroom. It is a struggle for me to get them to
interact with their notes and textbook, they usually turn right to me for the
answers, and they don’t rely on their peers as resources or experts.

As I observed my students working, I
heard them discussing why a particular answer was true or false, they were
critiquing the arguments that had been provided by the selected students, and
they were working together to draw a conclusion. I even heard comments like, “I’m going to be
much more careful on my next test so that Ms. Balli doesn’t have to grade all
of this crap!” or “Oh no, I don’t think this is my work, but I know that this
is the way I did this problem, and now I see that it’s wrong.”

There was one student work sample
that I included because it was an example of an equation that had been set up
incorrectly, but yielded the correct answer.
This was an interesting discussion starter because students asked me,
“Would they get full credit? They got
the right answer!” Eventually students
began to realize that the importance did not rest in the correct answer, but
rather the correct method. It was
obvious that, to them, math is all about getting the correct answer, but they
were able to slowly move away from this because they saw evidence of getting
the right answer through an invalid process.
I believe that this was the start of a cultural shift in my classroom –
as their teacher, a correct answer is nice, but that is certainly not the only
thing that I am looking for.

When it came time to return the
tests, I did a short debrief with them about the whole re-engagement
experience. Several students stated that
they had never done anything like this before, and found it very useful. The majority of my students said that they
learned something from this lesson, and whether they scored an A or an F on the
first chapter test, they felt strongly about these particular problems that they
had examined and felt that they understood them better. Regardless of his or her grade on the test, I
did feel that each student was able to walk away from this experience with a
deeper understanding of the mathematics.

Just before handing back the tests,
I shared with my students some of the research that has been done with
relationship to feedback. The three
categories that were examined in this research study were teachers providing
only a grade (no feedback), teachers providing both written feedback and a
grade, and teachers providing only feedback (no grade). The results showed that the greatest amount
of student learning was from the population of students who only received
feedback, no formal grade. I had a good
laugh with my students, because despite the findings from this research, I had
provided them with both a formal grade and feedback. I did this because I knew that I wanted to
have my students participate in a re-engagement lesson prior to getting their
tests back, so I felt that this would be a vehicle for student learning,
regardless of me providing them with a grade.

As the research predicted, once
students received their tests with both written feedback and a formal grade,
they appeared to be ready to move on to the next topic of discussion, as there
was little interest in examining their mistakes. However, I will say that they were able to
connect mistakes that they made to mistakes that they saw from the student work
samples. The work samples may not have
been a photocopy of their work, but the same mistake was made, and I do feel
that there was something learned from making this connection.

An observation that I made about my
six Geometry classes was that, in some instances, there was not as much buy-in
from my B-Day students (second day). My
B-Day classes have fewer Honors students, as the Honors classes (English,
History, and Science) are offered more on B-Days, so I do find more Honors
students in my A-Day classes. However, I
am not sure that the schedule of classes is the only culprit. When I made photocopies of student work, I
only made copies from my B-Day classes, so I am wondering if they felt
discouraged because they recognized some of their work. Are the students in these classes not as
confident? I am not sure what the
reasoning is for the lack of connection, but I am interested to see that if I
include work from both days, would there be an increase in buy-in?

Finally, I want to take a moment to
reflect on the two successful re-engagement lessons that I have undertaken. The first re-engagement lesson that I taught
successfully was using a MARS task that I had given my students as a formative
assessment. I was teaching a unit on
surface area and volume and wanted to see how much they were able to apply to a
composite three-dimensional figure. The
task involved finding the volume of a wine-shaped glass that was part cylinder,
part hemisphere. Students struggled with
the composition of volume; forgetting to divide the volume of the sphere by
two, or did not remember the four-thirds from the sphere formula. There was a wide range of issues.

When I did the re-engagement lesson,
I provided students with six samples of student work, which they were asked to
make sense of and then determine which student had the correct answer. Without exception, every student in my three
different classes was able to articulate why “Student B” was correct. It was an amazing sight to see and I was
confident that my students had really made a connection to the mathematics from
the task.

Fast-forward a week and I am now giving them their summative
assessment. The end of unit test
included a problem asking them to find the volume of a hemisphere, and I was
devastated to find that less than a quarter of my students were successful with
this task. This made me question the
impact of the re-engagement lesson. Was
it not all that it was cracked up to be?
Was it really that effective? Or
in that moment during the re-engagement lesson did they actually connect to the
mathematics and were unable to make the connection to this new problem? Is the issue in their ability to see how
these concepts work together?

I am finding that this year I am eager to assess my students,
simply so that I can take them through the process of re-engagement. I am also excited to explore the applications
of re-engagement outside of assessment, as well as outside of mathematics. Would a re-engagement lesson be applicable or
effective in Science or Spanish? What
about English or History? As I gain
confidence in my teaching, I am open to sharing my thoughts and experiences
with others, because I know that there are so many things that I have yet to
learn. Not only have I learned from
professional development seminars, which are lead and populated by adults, but
even more so I have learned from the people that are inside the walls of my
classroom everyday; my students.

### Animoto and Geometry

I always want my students to make connections between math and their surroundings, especially when it comes to Geometry. We are just now wrapping up the chapter on parallel lines cut by transversals, and I think there are so many examples of some of the Geometric ideas that we cover in their everyday environment. So, I had them download the free app Animoto and it was great because more than half of each class had the capacity to do so, which made groups small and doable.

I had students get into groups of two and walk around campus looking for various Geometric elements. I had a list of twelve, which they had to find a minimum of ten. The list included:

Overall, I found that the students took the activity seriously. They loved being outside and making connections to what they were learning in class. They still relied on me for things like, "Mrs. Murk, would this be an example of Parallel Planes?" They still struggle with self-starting, but for the most part, they took the initiative.

Something that I would change for next time is I would be stricter, or more descriptive, as to what the pictures are of. I don't want students to find two lines that are intersected by a transversal and use that picture for three or four different Geometric idea. I just find this boring and not pushing the students very hard to be creative.

I've included some of my favorite videos below.

### New Things on the Horizon

So, I know that as teachers we live for our summer holiday and the time off for relaxation and rejuvenation; but I can't seem to turn off my work mind. I love getting online through my lap top or my iPad and checking in to communities like Edmodo or Facebook to see what's new. I think that a big reason for this is because of the transition to Common Core that will be taking place this year and next in my classroom. I say classroom because I am 100% committed to making changes in my instruction, but I don't know what the goals area for my department, school, or district are as of yet.

One thing that I have been working on is planning Common Core Math units that will be implemented this year. I brought one into my curriculum this year and it was successful in many ways. I'm anxious about all of the work that will need to go into the other units to follow; especially because of the lack of support from my district. I feel like the only one doing this kind of work, so it's a lonely road.

Another element of my teaching that I have been revamping is my use of technology in my classroom. I have been using apps and online communities to try to keep my students connected and interested in their learning. The challenge for me will be to sustain the use of these items in my work. For example, I have created an assignment on Edmodo that my students need to complete, but it's more just as a trial because I don't know how it all works. I want to see if it's a useful tool, and if it is, I want to continue to use it.

I want to stay positive and continue to think outside the box when it comes to my teaching, but at the same time, I do not want to constantly be trying new things for the sake of trying new things. I would like to find something that I think is useful, effective, and meaningful and make it work for me and my students.
