The document defines laboratory method as a teaching procedure that uses experimentation and hands-on experiences with materials and equipment to discover facts and study scientific relationships. It is used not only in the physical sciences but also in other subjects. The goals of the laboratory method are to provide students with firsthand experiences in experimentation to increase interest, allow participation in original research, and develop skills in using lab tools and instruments. The method can be either experimental, with an emphasis on discovery and problem solving, or observational, with a focus on acquiring facts through demonstrations and activities.

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.
