2.  Usedto designate a teaching procedure that
uses experimentation with apparatus and
materials to discover or verify facts and to
study scientific relationship.
 Used not only in the physical sciences but
also in home economics and manual arts.
 Defined as a teaching procedure dealing with
firsthand experiences regarding materials or
facts obtained from investigation or
experimentation.

3. by John Walton (1966)
 Togive firsthand experience in the
laboratory which may increase student
interest
 Toprovide student participation in original
research
 To
develop skill in the use of laboratory
equipment and instruments.

4.  Experimental – aims to train pupils in solving
with incidental acquisition of information
and motor skill.
 Emphasis: discovery, original procedure, analysis, and
solution of problems.
 Observational
– the acquisition of facts is the
dominant aim.
 Facts can be acquired through activities such as visit to
museums, exhibits and art galleries, watching
demonstrations, listening to lectures, viewing films,
and going on field trips.

5.  IntroductoryStep. Includes determination of
the work to be done. The teacher should
motivate the work at this stage.
 Work Period. No matter what they are
working on, the students will gain experience
in scientific procedure, handling raw
material, and using tool.
 Culminating Activities. Decide on how to
present results of their individual work in the
following forms: (next slide)

6.  Explaining
the nature and importance of the
problem the group had worked on
 Reporting data gathered or other findings
 Presentingillustrative material or special
contributions
 Special reporting and exhibition of work by
those with individual projects
Exhibiting various projects and explanation by
their sponsors.

7.  Laboratory exercises should be adapted to
broader social needs.
 Material must be socially valuable and
relevant.
 Problems should be real, interesting, and
adapted to the learner’s level.
 Laboratory exercises must grow out of
problems.
 Laboratory manual should be chosen with
care
 The teacher must be a skillful director of
problem solving and of study.

8.  Learning by doing
 Impressionsthrough several sense make
learning more effective
 Undergoing actual experience is more vivid
 It is a direct preparation for life.

9.  Uneconomical way of learning
 Becomes mechanical – at times.
 The expensive materials sometimes does not
justify results.
 Loss
of time occurs due to indiscriminate
overuse of the method.
