ASSIGNMENT 1—PLEASE SOLVE AND ANSWER THE QUESTIONS IN RED

In Mr. Sullivan's class, which like all the classes in the district is heterogeneous. He taught his students how to find interest rates compounded annually. He presented to his students the formula A=P * (1 + r)t.

He defined his variables: A = amount of money; P = principal amount; r = rate of interest; t = time in years.

The class practiced many examples that were presented in the fashion:

If P = $1000; r = 6%, t = 5, find A.

If A = $4917.88; r = 7%; t = 7 find P.

They were assigned homework problems that reinforced the day's lesson. Since the students were able to start the homework in class, he was sure they knew how to do it.

In his district, all students take quarterly benchmark assessments. Teachers following the district pacing guide know what concepts will be assessed and as a result tend to follow the pacing guide pretty faithfully. As expected, working with compound interest was on the spring benchmark assessment. Students were asked to solve the following problem.

You deposited $10,000 in an account that pays 12% interest compounded annually.

a. Make a table of your data.

b. Write an equation to determine the amount, A, you will have in t years.

c. How much will you have in 5 years?

d. In how many years will you have $20,000?

e. Using only words, write a general equation for an exponential function.

On this benchmark assessment given to all grade 8 students in the district, Mr. Sullivan's class failure rate exceeded that for the whole district and he was utterly confused as to why. When Mr. Sullivan was discussing his class results with the district mathematics coordinator he expressed dismay over the results. He repeatedly stated that he had taught the material, and the students seemed to understand it. He asked to see student work from some other teachers so he could see for himself that his was the worst in the district.

If you were the mathematics curriculum coordinator, how would you respond to Mr. Sullivan?

Most educators agree that it is no longer reasonable to talk about "regular education" as though it is separate from addressing the needs of children who require specialized and specific academic services. Most classrooms are now comprised of students who:

•Are identified as having a specific learning disability

•Are from different cultural backgrounds

•Are at risk due to social inequities

•Are female

•Do not speak English

•Are mathematically talented

Let's think about Mr. Sullivan's approach to teaching mathematics. As we explore his classroom and his teaching style we must also assume his class is comprised of students with the same attributes as listed above.

How might the following suggestions impact the teaching and learning of Mr. Sullivan's students?

1. Instruct using a problem-solving based classroom in which:

1.Each problem has multiple entry points.

2.Multiple representations are required, tables, graphs, and equations.

3.Heterogeneous grouping of students is utilized.

4.Students work together in small groups to solve the problems.

5.Differentiated tasks are developed.

6.Each student is carefully listened to.

A. What are the benefits?

B. How would this approach differ from his current style?

2. Multiple representations are required, tables, graphs, equations

1.Provide a template with space for a table, a graph, an equation and a communication piece that mandates a justification for the answer.

2.Utilize the graphing calculator as a means of checking their work.

A. What are the benefits?

B. How would this approach differ from his current style?

3. Plan for Multiple Entry Points

1.Encourage multiple strategies for solving the problem

2.Use or have available manipulative models

3.Suggest multiple representations

A. What are the benefits?

B. How would this approach differ from his current style?

4. Plan Differentiated Tasks

1.Have available multiple versions of the problem

2.Present a situation with related but different questions that can be asked

3.Use workstations so for a given concept students can be assigned to specific stations based upon their abilities and readiness

A. What are the benefits?

B. How would this approach differ from his current style?

5. Use Heterogeneous Groupings

1.Mix a visual learner with a concrete learner with an abstract learner

2.Mix a verbal learner with a pictorial learner

3.Capitalize on the diversity within the class

A. What are the benefits?

B. How would this approach differ from his current style?

6. Listen Carefully to Students

1.Sit quietly in the groups to hear what students are thinking

2.Encourage students to report out their findings in a summary of the problem-solving

3.Rotate the reporter from each group so all students have an opportunity to "teach their peers"

A. What are the benefits?

B. How would this approach differ from his current style?

7. Drill and Practice with a Twist

1.Practice different problems or tasks addressing the same concept spread over numerous class periods

2.Have students go to the board in a round robin fashion or use individual white boards to practice certain skills in an environment that allows for immediate intervention if errors are present

3.Time tests/quizzes do not validate deep thinking

4.Traditional drill leaves little excitement in even the best student

5.Traditional drill provides for automatically or instant recall

6.Practice provides increased opportunity to develop conceptual ideas and useful connections, a greater chance for all students to understand, and a clear message that mathematics is about figuring things out and making sense of the mathematics

A. What are the benefits?

B. How would this approach differ from his current style?

ASSIGNMENT 2: REPLY TO THE TWO POSTS BELOW

I really enjoyed the article entitled, “Are Issues of Equity in Mathematics the Same across Racial, Ethnic, Class and Gender Boundaries,” because it talks about how though there are different minority groups, that we can kind of all join together to fight for our rights. In the same light, they also describe that though these groups can fight together, they all are very different and will need many different things, and many may not ever be able to understand the different hardships that another is going through. I really enjoyed reading about the culture of women, and how some people don’t even think that there is a culture for women.

The second article, “Creating Multiple Representations in Algebra: All Chocolate,” I really liked how the author talked about the different ways there was success in the classroom and how the students achieved knowledge and felt confident in their answers and what they were doing. I especially liked the section on modifications because it told what they would do in this activity for younger students or students with special needs, which shows they were thinking about them, and different entry points, which is great!

In your classroom do all students (male, female, different abilities)...

1. have your encouragement to share their thinking and reasoning about the problems they solve in small groups or with the class as a whole? yes

2. receive quality and varied feedback (questioning, constructive criticism, etc.)? yes

3. expect to take responsibility within small groups? yes

4. gain practice trying out invented algorithms as well as conventional strategies for solving problems? yes

5. have an opportunity to work with manipulatives and other hands-on learning tools? yes

6. follow established rules for participation (such as calmly raising a hand or waiting to be called on) so that no one student dominates class time and teacher attention? yes

7. have a chance to use examples and experiences that draw on their own interests? yes

8. have equal time at the computer and use the computer for mathematical problem-solving (rather than only for practice with isolated skills, such as number facts)? yes

9. have exposure to math problems grounded in real-life situations that include opportunities to be "messy" (estimation, making predictions, multiple problem-solving methods)? yes

Do you...

1. use language that is inclusive for all kinds of students? yes

2. provide activities for students to develop those skills, such as spatial skills and higher order problem-solving, that have "disparate developments in students"? yes

3. allow adequate wait time (3-5 seconds) for students to answer a question? Not all the time.

4. hold high expectations for, and communicate those expectations to, all students? Could be better at this.

5. find ways to engage all students in class discussion, even those who are more quiet or passive? yes

6. analyze your interactions with students to check for biased language and stereotyping? no

7. try to use software that is free of harmful gender or other stereotypes and that is mathematically rich? yes

8. encourage girls to be confident in their abilities as mathematicians? Could be better

9. encourage girls to pursue math in high school, college, and beyond? yes

10. structure problem-solving activities so that they are cooperative/collaborative rather than competitive? Could be better

11. strive to call on a variety of students, and especially work to involve students who tend not to participate in discussion? yes

I found the first article, by Jay Hill, somewhat discombobulating. I believe I got hung up on the phrase “culture of women” and the subsequent sentence, “this means a full acceptance that women have a different view of the world (and, consequently, mathematics) that is as valid as world views held by men.” I don’t particularly like thinking of academic subjects as gendered, especially math, perhaps because I’m sensitive to the fact that giving something a feminine gender often weakens it.

I agreed wholeheartedly with the final sentence, which said, “There are so many forces at work that to ignore the influence of gender and to focus on ethnic or SES group membership would be a disservice to all, particularly when one must note that gender is a factor that cuts across all races, ethnicities and social classes.” Though that made “the culture of women” more unclear to me, as, as it states, “female culture” necessarily incorporates all other types of cultures. I’m not saying there aren’t things that relate to women alone, I just find it hard to compile them into a cohesive “culture.” Though, that may be a semantics issue.

As a prospective elementary school teacher, and one most comfortable with 1st to 4th grades I found the second article, All Chocolate, No Change, less than compelling. It did make me think about the fact that by working primarily with younger grades, my “higher” math (relative to basic addition and subtraction) has been sorely neglected, so was interesting reading from that viewpoint.

In your classroom do all students (male, female, different abilities)...

1.have your encouragement to share their thinking and reasoning about the problems they solve in small groups or with the class as a whole? Yes, I ask a lot of “Why” questions.

2.receive quality and varied feedback (questioning, constructive criticism, etc.)? I think so

3.expect to take responsibility within small groups? N/A

4.gain practice trying out invented algorithms as well as conventional strategies for solving problems? Not really. Though I don’t quite get this.

5.have an opportunity to work with manipulatives and other hands-on learning tools? Yes

6.follow established rules for participation (such as calmly raising a hand or waiting to be called on) so that no one student dominates class time and teacher attention? N/A

7.have a chance to use examples and experiences that draw on their own interests? N/A

8.have equal time at the computer and use the computer for mathematical problem-solving (rather than only for practice with isolated skills, such as number facts)? N/A

9.have exposure to math problems grounded in real-life situations that include opportunities to be "messy" (estimation, making predictions, multiple problem-solving methods)? N/A

Do you...

1.use language that is inclusive for all kinds of students? I think so.

2.provide activities for students to develop those skills, such as spatial skills and higher order problem-solving, that have "disparate developments in students"? N/A

3.allow adequate wait time (3-5 seconds) for students to answer a question? I catch myself answering too early often. I definitely need to work on this.

4.hold high expectations for, and communicate those expectations to, all students? I try to but it is an ongoing process. Much easier to say than do. How does one “communicate” high expectations?

5.find ways to engage all students in class discussion, even those who are more quiet or passive? N/A

6.analyze your interactions with students to check for biased language and stereotyping? No

7.try to use software that is free of harmful gender or other stereotypes and that is mathematically rich? N/A

8.encourage girls to be confident in their abilities as mathematicians? I really try to, although I worry that focusing attention on girls may be internalized as them needing more help, so I’m not sure I’m succeeding.

9.encourage girls to pursue math in high school, college, and beyond? N/A

10.structure problem-solving activities so that they are cooperative/collaborative rather than competitive? N/A

11.strive to call on a variety of students, and especially work to involve students who tend not to participate in discussion? N/A
