The Investigation-Colloquium
Method
The Investigation-Colloquium
Method was designed over three decades ago (Lansdown
et al., 1971) to provide a means for promoting new
student learning in science by connecting a concrete
experience with reasoning and language. The method
is based on the premise that through interaction
and dialogue students are more likely to make sense
of observations and generate questions that may
be systematically pursued in subsequent investigations.
The
following diagram illustrates the sequence of stages
in students' conceptual progress as described by
Lansdown (p. 121):

The
teacher plans the first stage to meet pre-determined
objectives. It may involve a hands-on engagement
by students or an observation of a demonstration.
This initial stage is often employed through the
use of an eliciting prompt (see The
Eliciting Prompt: Initiating Student Questioning
Via Spontaneous Observation at http://www.designedinstruction.com/learningleads/eliciting-prompt.html)
that evokes spontaneous reaction and observation
from students. The role of the teacher in creating
the situation that evokes these elaborations is
critical. They provide the spark and the interest
to promote the generation of questions by presenting
scientific problems initially in such a way that
they correspond and build upon experiences that
are familiar to students.
The
fundamental premise of the method is that we learn
by doing and then talking about our discoveries
and perceptions. Instructionally, as teachers mediate
the discussion portion of the process, they should
strive to redirect and connect students' thoughts
and ideas rather than lead the conversation. Again,
however, it is of significant importance that the
teacher remains involved, as discussed in the following
research sidebar.
The Investigation-Colloquium Method is both based
in solid learning theory and supported in scientific
research. Its initial development was influenced
heavily by Vygotsky's theories and research on the
development of thought and language (1962, 1978),
and subsequent research (Brooks, 1988; Trainor,
1978) indicates that the method effectively takes
advantage of the value of verbal interaction in
bringing order and understanding to children's experience
with a scientific concept. More recent literature
indicates increasing alignment with expert opinion.
The National Science Education Standards
(National Research Council [NRC], 1996) support
the idea of discourse (i.e., "(Teachers) orchestrate
discourse among students about scientific ideas"
and "...encourage informal discussion and structure
science activities so that students are required
to explain and justify their understanding...").

The term "colloquium" is now commonly
accepted and used to refer to gatherings and discussions
of professionals around a particular concept or
set of ideas or events. Through structured interactive
dialogue understandings are enhanced, perspectives
are challenged, and needs for further research are
established, both individually and as a collective
body.
