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.
Teaching Method - Laboratory Method
- 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.
