Research in common parlance refers to a search for knowledge. Once can also define research as a scientific and systematic search for pertinent information on a specific topic

. Common Ways Of Knowing…
. Personal Experience/Intuition
. Experts/Traditions/Authority
.Scientific Method

Why must we understand research?
.
Help Make Informed Decisions
. Need To Produce Research In Career
. Evaluating Research In The Media
. Assist In Classes

Scientific And Disciplined Inquiry Is An Orderly
Process, Involving:
. Recognition And Identification Of Topic To Be
Studied (“Problem”).
. Description And Execution Of Procedures To
Collection Information (“Method”)
. objective data “analysis”
. Statement Of Findings (“Results”)

. Basic…
…The Process Of Collecting And Analyzing Information
To Develop Or Enhance A Theory .
. Applied…
…conducted for the purpose of applying or testing theory and evaluating its usefulness for solving problems

Evaluation…
…Concerned With Making Decisions About The Quality,
Effectiveness, Or Value Of Programs, Products, Or
Practices

1. Quantitative…
…Collects And Analyzes Numerical Data Obtained From Formal
Instruments .
2. Qualitative…
…Collects And Analyzes Nonnumeric Data Over An Extended
Period Of Time

Research methods
1. Qualitative Research :
That Depend Primarily On The Search For Quality Of Data In The Form Of
Notes And Written Comments, Opinions Or Watch Or Audible.
2. Quantitative research on research that require digital data and arranged either in the form of tables or categories or classifications or graphs. Often such data is obtained from the readings of scientific devices and tools used in the search, Such measurements weights and lengths and sizes, ages and time and capacity, quantity, distances and temperatures, income and other quantitative data types.

Types of Variables in Research
1. Independent…
…An Activity Or Characteristic Believed To Make A
Difference With Respect To Some Behavior
2. Dependent…
…the change or difference occurring a a result of the independent variable

Tools Of Scientific Research

1-samples
2. The Data Collection Tool
-Questionnaire
- Interview
- Note

Research Methodology
1. Descriptive Approach.
2. Historical Method.
3. The Experimental Method.

Learning Outcomes
