2The 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).

4Constructivism????
- 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.
5Social 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.

7Contructivist 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.
8The 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.)
10Actions 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.
11Interpretation 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
