Principles of Teaching The Laboratory Method

What is The Laboratory

Method?

Laboratory Teaching Methods This methods is one of the important

methods of teaching science and it forms an integral part of effective science teaching. Under this methods, teachers encourages the students to derive various scientific laws and principle on their own by getting personally involved in the experiment work.

• Scientific Method is define as the principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of problem, the collection of data through observation and experiment, and the formulation and testing of hypothesis.

2 Major Types of Laboratory Methods

1. Situation where students work in the laboratory- In this situation student’s work informally in pairs or groups where equipment cannot go around all students individually.

2 Major Types of Laboratory Methods

2. Demonstration- is a process of presenting or establishing facts or principles. It is a procedure of doing or performing something in the presence of others or either as a means of showing them how to do it or illustrating a principle.

MAJOR GOALS OF LABORATORY WORKS

Teaching Manuals and Observational skills relevant to the subject

Improving understanding methods of scientific inquiry

Developing problem solving and doing by self skills.

CORRECT METHODS OF TEACHING IN LABORATORY

1. Self Preparation2. Right Explanation3. Starting Experiments4. Handling instruments5. Explaining observations6. Writing reports7. Lab safety

Advantages of Laboratory Method1. Students learn by doing and come in contact

with raw data or materials in teaching learning process.

2. Develops the power of observation and reasoning.

3.Develops the scientific attitudes4. Gives an understanding of what research is

and how to apply the scientific method

Advantages of Laboratory Method

5. Gives training in organizing data gathered from real materials object and how these objects are manipulated to attain the objectives.

6. Since students come in contact with real life situations, it can be a preparation for solving real life problems

Disadvantages of Laboratory Method

1. Uneconomical way of learning in time and material.

2. Does not give much training in verbal expression and when the same equipment is used most of the time, its use becomes mechanical i.e., used without much thinking anymore
