Title: Learning Mathematics: Implications for Teaching


1
Learning Mathematics Implications for Teaching
  • Anthony Orton
  • Issues in Teaching Mathematics
  • (Ed. Orton, A, Wain, G.)

2
The Construction of Meaning
  • Unless pupils have an adequate understanding of a
    procedure, unless they have in some way made it
    their own, there is often resistance to trying to
    use it.
  • Pupils often benefit if they understand why a
    procedure works as well as simply being able to
    carry out the procedure (instrumental
    understanding).

Constructivism????
  • We all have to make sense of the world ourselves,
    and we continue to develop our understanding
    throughout life.
  • Hypotheses
  • Weak Knowledge is actively constructed by the
    learner, not passively received from the
    environment
  • Radical coming to know is an adaptive process
    that organizes ones experiential world it does
    not discover an independent, pre-existing world
    outside the mind of the knower.

5
Social Constructivism (Socio-constructivism)
  • meaning, or understanding, is being to some
    extent actively negotiated through such
    discussion.
  • Teachers role to help students develop skills
    of constructing, evaluating and modifying
    concepts The teachers role therefore is to work
    to improve the quality of the discussions rather
    than to focus from the beginning on the
    correct answer.

Contructivist Teaching Experiment (Kamii, 1989)
  • Children invent arithmetic themselves
  • belief that children acquire mathematical
    knowledge not by internalizing rules imposed from
    outside but by construction from the inside
    through their own natural thinking abilities
  • errors arise because they are thinking,
  • task of teacher is not to correct from outside,
    but to create a situation in which the children
    will inevitably correct themselves.

8
The twelve strategies for teachers to become
constructivists(Brooks Brooks)
  • (1) Constructivist teachers encourage and accept
    student autonomy and initiative.
  • (2) Constructivist teachers use raw data and
    primary sources, along with manipulative,
    interactive, and physical materials.
  • (3) When framing tasks, constructivist teachers
    use cognitive terminology such as "classify,"
    "analyze," "predict," and "create."
  • (4) Constructivist teachers allow student
    responses to drive lessons, shift instructional
    strategies, and alter content.
  • (5) Constructivist teachers inquire about
    students' understanding of concepts before
    sharing their own understandings of those
    concepts.
  • (6) Constructivist teachers encourage students to
    engage in dialogue, both with the teacher and
    with one another.

9
  • (7) Constructivist teachers encourage student
    inquiry by asking thoughtful, open-ended
    questions and encouraging students to ask
    questions of each other.
  • (8) Constructivist teachers seek elaboration of
    students' initial responses.
  • (9) Constructivist teachers engage students in
    experiences that might engender contradictions to
    their initial hypotheses and then encourage
    discussion.
  • (10) Constructivist teachers allow wait time
    after posing questions.
  • (11) Constructivist teachers provide time for
    students to construct relationships and create
    metaphors.
  • (12) Constructivist teachers nurture students'
    natural curiosity through frequent use of the
    learning cycle model. (The learning cycle model
    consists of discovery, concept introduction, and
    concept application.)

10
Actions and changes need to occur for creating
constructivist teachers.
  • (1) Structure preservice and inservice teacher
    education around constructivist principles and
    practices.
  • (2) Jettison most standardize testing and make
    assessment meaningful for students.
  • (3) Focus resources more on teachers'
    professional development than on textbooks and
    workbooks.
  • (4) Eliminate letter and number grades.
  • (5) Form school-based study groups focused on
    human developmental principles.
  • (6) Require annual seminars on teaching and
    learning for administrators and school board
    members.

Interpretation Construction (ICON) Design Model
John B. Black and Robert O. McClintock
http//www.ilt.columbia.edu/ilt/papers/ICON.html
  • Observation Students make observations of
    authentic artifacts anchored in authentic
    situations
  • Interpretation Construction Students construct
    interpretations of observations and construct
    arguments for the validity of their
    interpretations
  • Contextualization Students access background and
    contextual materials of various sorts to aid
    interpretation and argumentation
  • Cognitive Apprenticeship Students serve as
    apprentices to teachers to master observation,
    interpretation and contextualization

12
  • Collaboration Students collaborate in
    observation, interpretation and contextualization
  • Multiple Interpretations Students gain cognitive
    flexibility by being exposed to multiple
    interpretations
  • Multiple Manifestations Students gain
    transferability by seeing multiple manifestations
    of the same interpretations
