Instructional scaffolding is a learning process designed to promote a deeper level of
learning. Scaffolding is the support given during the learning process which is
tailored to the needs of the student with the intention of helping the student
achieve his/her learning goals (Sawyer, 2006).
There are a number of ways in which
teachers can assist students in developing language and subject matter
knowledge from the interactive, sociocultural perspective sketched here. One such
way, scaffolding, is particularly consonantwith sociocultural theory (SCT) and
is well suited to English language learners.
A.
DISCUSSION
1. Learning from a Sociocultural
Perspective
The main tenets of vigotsky’s learning theory can be
summarized as follow:
·
Leaning precedes development.
·
Language is the main vehicle (tool) of
thought.
·
Mediation is central to learning.
·
Social interaction and internalization.
·
The Zone of Proximal Development (ZPD).
2.
Scaffolding
Creating
contexts for linguistic and academic learning in the ZPD occurs in part through
the scaffolding of social interaction. Scaffolding is closely related to the
ZPD. In fact, it is only within the ZPD that scaffolding can occur. As we saw
above, working in the ZPD means that the learner is assisted by others to be
able to achieve more than he or she would be able to achieve alone. Scaffolding
refers to the detailed circumstances of such work in the ZPD. According to
David Wood, scaffolding is tutorial behavior that is contingent, collaborative
and interactive (Wood, 1988: 96).
a. Scaffolding as structure and
process
The
original idea of scaffolding comes from the work of Jerome Bruner, who defines
scaffolding as a process of ‘setting up’ the situation to make the child’s
entry easy and successful and then gradually pulling back and handing the role
to the child as he becomes skilled
enough to manage it. (Bruner, 1983: 60)
b. Features of pedagogical scaffolding
There are six features of pedagogical scaffolding,
among others are:
·
Continuity
Tasks
are repeated, with variations and connected to one another (e.g. as part of
projects).
·
Contextual support
Exploration
is encouraged in a safe, supportive environment; access to means and goals is
promoted in a variety of ways.
·
Inter subjectivity
Mutual
engagement and rapport are established; there is encouragement and
nonthreatening participation in a shared community of practice.
·
Contingency
Task
procedures are adjusted depending on actions of learners; contributions and
utterances are oriented towards each other and may be constructed (or, see
below, vertically constructed).
·
Handover/takeover
There
is an increasing role for the learner as skills and confidence increase; the
teacher watches carefully for the learner’s readiness to take over increasing
parts of the action.
·
Flow
Skills
and challenges are in balance; participants are focused on the task and are ‘in
tune’ with each other.
c. Scaffolded interaction
differentiated from IRF
Often
the scaffolding process arises in a context of spoken interaction, when the
utterance of one participant is completed or taken further by the utterance of
another participant. Bruner has called this kind of collaborative talk
‘ratchet-like’ (cited in Cazden, 1992: 103). In classroom settings, it is
important to understand the difference between spoken interaction that
scaffolds student learning and interaction that imposes a ‘recitation script’,
as Tharp and Gallimore (1988) call it. Most teacher- student talk is of the
scripted type (Wells, 1999) and is commonly known asScaffolding Instruction for
English Learners 165 Initiation-Response-Feedback (IRF).
d. Beyond the expert-novice context
So
far we have discussed the ZPD and scaffolding from the perspective of a more
knowledgeable person (a teacher or parent) interacting with a less
knowledgeable person (a student or child). However, in the work of several
researchers (Donato, 1994; Gibbons, 2002; Mercer, 1995; Rogoff, 1995), the idea
of scaffolding has been expanded to include no only an expert-novice
relationship, but also a relationship of equal knowledge, such as in a group of
learners working on a shared task.

Scaffolding
instruction for English Language
learners in secondary Schools
Because scaffolds are by definition temporary, as the teacher
observes that students are capable of handling more on their own, she gradually
hands over responsibility to them. And the teacher carefully monitors the
learners’ growing understanding and developing academic skills.
Types of
instructional scaffolding to use with English learners
a.
Modelling
When
introducing a new task or working format, it is indispensable that the learners
be able to see or hear what a developing product looks like. The example;
In my chemistry class I can always
do well because the teacher first demonstrates an experiment, and then we try a
similar one.
b.
Bridging
-A common
bridging approach is to activate students’ prior knowledge.
-Another important aspect of
bridging is establishing a personal link between the students and
the subject matter.
-Other ways of bridging
include asking students to share personal experiences related to the theme. For
example, as a way of preparing students to read Francisco Jimenez’s short
story.
c. Schema
building
Schema, or
clusters of meaning that are interconnected, are how we organise knowledge and
understanding. If building understanding
is a matter of weaving new information into pre-existing structures of meaning,
and it becomes indispensable for teachers to help English Language Learners see
these connections, through a variety of activities.
d.
Re- presenting
text
In terms of language use, this continuum starts with asking students to say what is happening
(as in drama or dialogue), then what has happened (narrative, reports), then
what happens(generalisations in exposition ) and, finally, what may happen
(tautologic transformations, theorising). Short stories or historical essa, for
example, can be transformed into dramas or personal narratives.
The task is for students to re-present the article as a play. The
teacher presents small groups each with a scenario that corresponds to a
section, or moment, in the text.
e. Developing metacognition
It refers to the ways in which students manage their thinking, and
it includes at least the following four aspects:
1)
Consciously
appling learned strategies
2)
Knowledge and
awareness of strategic
3)
Monitoring,
evaluating, and adjusting performance during activity; and
4)
Planning for
future performance based one evaluation of past performance.
