Is the experimental method used in the
education?
The quasi-experimental method and
examples

3. It is a method or procedure
derivative from the practice and
experience that consists of a
systematic
observation, measurement, and
experiment, and the
formulation, testing, and
modification of hypotheses.

4.  Observation: Consists in data
selection.
 Hypotheses: This are the rational
suppositions get from the observed
data.
 Hypotheses Explanation: It is the
explanation of mathematics systems
to the hypotheses get before.
 Experimentation: Confirm or
refute the hypotheses.

5. Three Important reasons:
 The human being acts depend on
the context.
 The result of the research can be
manipulated.
 It is not possible generalized data.

6. Quasi-experimental research
may look very much like true
experimental research in that it
does involve the manipulation
of an independent variable.
However, it is not the same as
true experimental research
because quasi-experimental
research studies lack one or
both of the essential properties
of randomization and a control
group.
