Concepts of Number Head Together (NHT) Technique
1.
Definition of Number Head Together (NHT) Technique
According to Jacobs. G and Hall. Y (1994: 2). Define Numbered Heads Together encourages successful group functioning because all members need to know their group’s answers and because when students help their groupmates, they help themselves and the whole group.
Base on Lou. M. M (2005: 7) states this versatile can be used effectively for both memory level and higher order thinking activities. Instead of answering questions, learners can brainstorm ideas, solve a problem, draw a diagram, invent a product, etc.
In addition (Harper,
Maheady & Mallette, 1994: 32) Number Head Together is one of the
cooperative learning structures designed to engage all students to promote
their academic and social interactions.
According to
Kagan in (Dwi Andari A. W. 2012: 7) Numbered
Heads Together is a
cooperative learning strategy,
that holds each
student accountable for
learning the material. Students are placed in groups and
each person is given a number (from one to the maximum number in each group).
Based on the state above the writer
have conclude that Number Head Together (NHT) is a strategy to improve the
student ability with make a group, the student will be understand about the
material given.
2. The procedures of
structuring NHT are described as below (Kagan, 1989):
a.
Students are put into
heterogeneous teams and each has a number.
b.
Students sit together in a
circle when the instructor implements the whole class teaching.
c.
The instructor asks the
whole class a question, which is usually a high consensus one. Students
actually put their heads together to think of the best answers and make sure
every group member can answer the question.
d.
The instructor randomly
chooses a number, and only students with that number can respond to the
question.
e.
The instructor evaluates the
answers and rewards specific teams accordingly.
In addition Kagan (2009) the steps for using Numbered Heads
Together are:
a)
Students Count Off - In each
group, students count off by the number of students in the group. If you have
groups of six students, students count off 1-6. They do this in whatever order
they choose. If there is a group with only five students in it, one student
will have two numbers.
b)
Pose a question/problem -
The teacher poses a question or problem to the class and tells groups they have
a specific amount of time to come to consensus on an answer. The amount of time
allotted will depend on whether the question is one with a specific “right”
answer or a more open-ended question.
c)
Students put heads together –
The students put their heads together to make sure that everyone in the group
has the answer or answers.
d) Teacher calls a number – The teacher calls a number from 1-6. All
the students with that number stand. One of the standing students is called
upon to give their group’s answer. Standing students with different answers can
be called upon to explain their group’s thinking.
