Laboratory and demonstration method

Laboratory and demonstration methodLaboratory and demonstration methodAt the end of the discussion, the students will be able to:Classify the different types of laboratory and demonstration method

Identify the different steps of laboratory and demonstration method

Differentiate laboratory and demonstration method

Laboratory methodUtilizes raw data or material things to produce better understanding of the subject matter or lesson.

Learning by doing.

Used to designate a teaching procedure that uses experimentation Laboratory methodAimsLaboratory methodTo give firsthand experience in the laboratory which may increase student interest

To provide student participation in original research

To develop skill in the use of laboratory equipment and instruments

Two typesLaboratory methodExperimental - aims to train pupils in problem solving with incidental acquisition of information and motor skills.

Observational - the acquisition of facts is the dominant aim of the method. AdvantagesLaboratory methodApplies learning by doing

Develops the power of observation and reasoning

Develops scientific attitude

Advantages

Laboratory methodGives an understanding of what research is and how to apply scientific method of research

Gives training in organizing data

Preparation for solving real life problems

DisadvantagesLaboratory methodUneconomical way of learning

Does not give much training in verbal expression which makes the lesson mechanical

Laboratory methodSteps in Laboratory MethodPreparationLaboratory methodReview past lesson.

Raising and defining the work to be done

Expected learning outcomes

PlanningActual work periodLaboratory methodWork under instructors supervision

The students may be assigned individually, by group or a committee in which the tasks are sometimes divided by its members

A single study may last for few daysActual work periodLaboratory methodThose who work fast may be given incentives or additional assignment for additional credits

Culminating activitiesLaboratory methodReporting what is worked on by individuals or groups in plenary session of the class

The reports may be compiled and reproduced for the benefit of the class to review for an evaluation or test.

After each report, questions may be asked concerning the report

Lecture Demonstration methodCombination of lecture and demonstration

This method of teaching is used frequently in biological and physical sciences

With this method, if it is executed properly, it enables the student to understand the lesson within a given period of timeLecture Demonstration methodIt is as effective as the individual laboratory method

Better compared to mere oral explanaitionLecture Demonstration methodAimsLecture Demonstration methodTo teach a skill, concept or principle

To demonstrate delicate and dangerous works involving careful manipulation.

To let teachers participate in demonstration classrooms to help improve their own teaching strategies.TypesLecture Demonstration methodExpository designed to impart information directly or to illustrate a skill as students observe.

Questioning designed to foster discovery of a concept or its application.Lecture Demonstration methodSteps in Lecture Demonstration MethodAdvantagesLecture Demonstration methodIt follows a systematic procedure.

Possible wastage of time, effort and resources will be avoided.

It will not result to trial and error.

Curiosity and keen observing ability are instilled.DisadvantagesLecture Demonstration methodTends to foster passiveness and teacher-dependence on the part of the students.

Becomes a failure when the number of students is greater.DisadvantagesLecture Demonstration methodIt needs a lot of time for instructions and demonstration.

It requires a knowledgable and expert demonstrator.The chief difference between the two is that:Diffeerencesin the laboratory method, all the learners perform the experiment and learning by doing.

In the demonstration method, the teacher does the experiment while the class observes.
