Title: ACCESS FOR ALL: READING COMPREHENSION STRATEGIES FOR UNDERSTANDING AND SOLVING MATHEMATICS TASKS


1
ACCESS FOR ALL READING COMPREHENSION STRATEGIES
FOR UNDERSTANDING AND SOLVING MATHEMATICS TASKS
  • Carl Lager, PhD
  • University of California, Santa Barbara

2
Overview
  • Three problem situations will be used to
    identify, explicate, and model specific reading
    comprehension strategies in different contexts.
  • You will experience them as problem solvers
    and learn how to facilitate them with your
    students.

3
Large-scale assessment
  • Because for many students (ELs and non-ELs)
    mathematics problems are also language problems,
    lets experience a large-scale mathematics item
    (or four) like a English learner.
  • Youll get to work on four items projected on
    the screen. Youll have 90 seconds to work on
    each problem.

4
Raising our awareness
  • After 90 seconds have elapsed, Ill say time!
    You write your answer and the level of your
    confidence in the appropriate box on the
    worksheet.
  • Work silently and independently.
  • At the end, we will do a freewrite and share out.

Problem 1
  • El dueño de un huerto de manzanas manda sus
    manzanas en cajas. Cada caja vacía pesa k
    kilogramos (kg). El peso medio de una manzana es
    a kg y el peso total de una caja llena de
    manzanas es b kg. Cuántas manzanas han sido
    empacadas en cada caja?

6
Problem 2
  • El dueño de un huerto de manzanas manda sus
    manzanas en cajas. Cada caja vacía pesa k
    kilogramos (kg). El peso medio de una manzana es
    a kg y el peso total de una caja llena de
    manzanas es b kg. Cuántas manzanas han sido
    empacadas en cada caja?
  • A) b k C) b / a
  • B) (b - k) / a D) (b k) / a

7
Problem 3
  • El dueño de un huerto de manzanas manda sus
    manzanas en cajas. Cada caja vacía pesa 2
    kilogramos (kg). El peso medio de una manzana es
    0.25 kg y el peso total de una caja llena de
    manzanas es 12 kg. Cuántas manzanas han sido
    empacadas en cada caja?
  • A) 14 C) 48
  • B) 40 D) 56

8
Problem 4
  • The owner of an apple orchard ships apples in
    boxes that weigh 2 kilograms (kg) when empty. The
    average apple weighs 0.25 kg, and the total
    weight of a box filled with apples is 12 kg. How
    many apples are packed in each box?
  • A) 14 C) 48
  • B) 40 D) 56

9
Individual Freewrite (4 minutes)
  • 1) What specific meaning-making strategies did
    you employ and when?
  • 2) How effective were your strategies?
  • 3) How confident were you in your
    strategies/answers?
  • 4) What mental movies were you generating?
    What were you seeing?
  • 5) How did you feel?

10
Whole group share out
  • 1) What specific meaning-making strategies did
    you employ?
  • 2) How effective were your strategies?
  • 3) How confident were you in your
    strategies/answers?
  • 4) What mental movies were you generating?
    What were you seeing?
  • 5) How did you feel?

11
CAHSEE released algebra item (88, p. 32, CDE,
2006)
  • The owner of an apple orchard ships apples in
    boxes that weigh 2 kilograms (kg) when empty. The
    average apple weighs 0.25 kg, and the total
    weight of a box filled with apples is 12 kg. How
    many apples are packed in each box?
  • A) 14
  • B) 40
  • C) 48
  • D) 56

12
CAHSEE released item (88, p. 32, CDE, 2006)
possible challenges
  • The owner of an apple orchard ships apples in
    boxes that weigh 2 kilograms (kg) when empty.
  • Boxes? How many boxes are we talking about here?
    Is 2 kg the total weight of all the empty boxes?
    If so, dont I need to know how many boxes so I
    can divide that quantity by 2 kg to find the
    weight of one box?
  • Translation The owner of an apple orchard ships
    apples in boxes. Each empty box weighs 2 kg.

13
CAHSEE released item (88, p. 32, CDE, 2006)
  • How many apples are packed in each box?
  • Whos packing the apples? This passive voice
    (PV) construction is very common in mathematics
    texts because it purposefully focuses our
    attention on the subject of the action, the
    apples. However, by doing so, PV obfuscates who
    is doing the action, making the construction of a
    mental movie of the problem more difficult.

14
Reading mathematics texts/items
  • Vocab, syntax, symbols, multiple meanings of
    words make math reading difficult (Gullatt 1986
    Harris Devander, 1990)
  • Math texts require different reading demands than
    other texts (Bye, 1975)
  • lt90 meaningful words frustration (Betts, 1946)
  • Second language learning is more difficult when
    textbook English is the first English discourse
    very different from ordinary talk (Fillmore,
    1982)

15
Reading Comprehesnion
  • Step 1 in problem solving is understanding the
    problem (Polya, 1943).
  • Reading comprehension is critical to
    understanding the problem
  • Think about what you just experienced with the
    Spanish CAHSEE math item

16
The RRSG (RAND, 2002) defines reading
comprehension as
  • the process of simultaneously extracting and
    constructing meaning through interaction and
    involvement with written language. It consists of
    three elements the reader, the text, and the
    activity or purpose for reading.

17
The RRSG (2002) defines reading comprehension as
  • these elements interrelate in reading
    comprehension, an interrelationship that occurs
    within a larger sociocultural context that shapes
    and is shaped by the reader and that interacts
    with each of the elements iteratively throughout
    the process of reading.

RC Classroom Strategies - I
  • 1) Activate related prior knowledge and
    experience.
  • 2) Break down task into smaller chunks.
  • 3) Use manipulatives or real-world objects.
  • 4) Predict the problem.

20
RC Strategies - I
  • This problem will be presented, bit-by-bit, in 5
    stages.
  • At each stage, you will be given 1 minute to
    predict the problem. Generate as many possible
    problems as you can that fit the information
    provided.
  • At stage 5, you will receive the actual problem.
    Solve it.
  • When you finish, write down how and why your
    answer based on the paper version of the problem
    might differ from the answer for the real-world
    version.

21
RC Strategies I (10 minutes)
  • And away we go

22
Tennis Ball small group discussion(5 minutes)
  • What were some of your questions?
  • How, why, and when did they change?
  • Was there a progression or schema that organized
    the changes?
  • How and why would your answer based on the paper
    version of the problem differ from the answer for
    the real-world version?

23
Tennis Ball share out
  • What were some of your questions?
  • How, why, and when did they change?
  • Was there a progression or schema that organized
    the changes?
  • How and why would your answer based on the paper
    version of the problem differ from the answer for
    the real-world version?

24
Treismans Challenge (May, 2007)
  • We need to systematically and coherently go
    beyond generic instructional strategies to
    address EL needs through on-target long-term
    professional development
  • Borrow from Using the Language to Increase Deeper
    Mathematical Meaning and Understanding session
    (Martinez-Cruz and Delaney 2005)

25
(Posamentier and Salkind, 1996)
  • 1) Solve the following 3-part problem singly or
    with a partner. Write all work on the problem
    itself .
  • 2) When finished, circle your answers.
  • 3) Then, apply the KWC and CI strategies to the
    problem. Another words, answer in writing the
    questions Ill provide.
  • 4) You have 10 minutes. Go.

26
(Posamentier and Salkind, 1996)
  • A man buys 3-cent stamps and 6-cent stamps, 120
    in all. He pays for them with a 5.00 bill and
    receives 75 cents in change.
  • Does he receive the correct change?
  • Would 76 cents change be correct?
  • Would 74 cents be correct?

27
(Posamentier and Salkind, 1996)
  • A man buys 3-cent stamps and 6-cent stamps, 120
    in all. He pays for them with a 5.00 bill and
    receives 75 cents in change.
  • Does he receive the correct change? No
  • Would 76 cents change be correct? No
  • These apparent problems to find (Pólya, 1943) are
    really problems to prove (Pólya 1943).
  • NCTMs (2000) Grades 9 12 Reasoning and Proof
    standard (p. 342, p. 344)

28
Would 76 cents be correct?
  • A man buys 3-cent stamps and 6-cent stamps, 120
    in all. He pays for them with
  • a 5.00 bill and receives 75 cents in change.
  • Would 74 cents be correct? ???

29
(Posamentier and Salkind, 1996)
  • A man buys 3-cent stamps and 6-cent stamps, 120
    in all. He pays for them with
  • a 5.00 bill and receives 75 cents in change.
  • Would 74 cents be correct?
  • A) yes
  • B) Likely, but not certain (P S)
  • C) Possible, but not likely (me)

30
(Posamentier and Salkind, 1996)
  • A man buys 3-cent stamps and 6-cent stamps, 120
    in all. He pays for them with
  • a 5.00 bill and receives 75 cents in change.
  • Does vs could? No vs. No
  • Would vs. could? (76) No vs. No
  • Would vs. could? (74) ??? vs. Yes

31
(Polya, 1943 and Hyde, 2006)
  • Step 1 in problem solving is understanding the
    problem (Polya, 1943)
  • Hyde infuses Pólyas (1943) work with reading
    comprehension strategies to create his five-phase
    Braid Model of Problem Solving Situation,
    Representations, Patterns, Connections, and
    Extensions.

32
(Polya, 1943 and Hyde, 2006)
  • Two such strategies the KWC strategy and the
    Checking Inferences strategy were applied to this
    problem.
  • K What do I know for sure?
  • W What do I want to figure out, find out, or do?
  • C Are there any special conditions, rules, or
    tricks I have to watch out for?

33
Checking Inferences
  • What inferences did you make? Are the inferences
    accurate?
  • What information is implied by the problem
    writer?
  • What are the significances of these
    inference-implication interactions for problem
    solvers?

34
Awareness of potential ambiguity
  • MacGregor and Price (1999) define awareness of
    potential ambiguity as the recognition that an
    expression may have more than one interpretation,
    depending on how structural relationships or
    referential terms are interpreted (p. 457).

35
Awareness of potential ambiguity
  • The Northwest Regional Education Laboratory
    (NRWEL) mathematics problem solving scoring guide
    states that, with regard to insight, an
    exemplary solution should document possible
    sources of error or ambiguity in the problem
    itself (NRWEL 2000)

36
Metalinguistic awareness
  • Metalinguistic awareness - the reflection upon
    and analysis of oral or written language in
    mathematics (MacGregor and Price 1999 Herriman
    1991).

37
Wordwalking
  • Interpreting Does he receive the correct change?
    (explicitly asking about one transaction) as Is
    it possible he received the correct change?
    (explicitly asking about all possible
    transactions) is wordwalking (Mitchell 2001)

38
Wordwalking
  • Wordwalking - the changing of the original
    questions wording to convey similar meaning but
    actually change the problems mathematical
    structure.

39
In conclusion
  • In conclusion

40
The overriding challenge
  • For ELs (and some non-ELs), the ongoing triple
    challenge of handling everyday and mathematical
    English, unfamiliar contexts and cultural norms,
    and mathematics content, all at the same time
    during an on-demand assessment and classroom
    setting can be quite daunting.

41
NCTMs PSSM (2000)
  • Though NCTM (2000) expects secondary mathematics
    teachers to help studentslearn to read
    increasingly technical text (p. 351), many
    teachers not adequately prepared to do so (RAND,
    2002).

42
NCTMs PSSM (2000)
  • Telling students, and language learners in
    particular, to read mathematics problems
    carefully (NCTM 2000, p. 54) without teaching
    them how is innately unjust and unfair.

43
The RRSG (RAND, 2002)
  • Reading instruction is seldom effectively
    integrated with content-area instruction.
  • Teaching in the content areas relies on texts as
    a major source of instructional content.

44
The RRSG (RAND, 2002)
  • These texts are not designed as a context for
    comprehension instruction, but comprehension
    instruction that uses these texts may be crucial
    if students are to understand or learn from them.
