Last Updated on June 20, 2022 by Mostafa

Internet has played a very important role in serving researchers and scientists in various fields as tool for distance learning by providing many scientific sources that are accessible at any time and place. In this article, we will address 5 of the most important scientific search engines on the internet. They include many research papers and Ph.D And Master theses, in addition to a lot of scientific references in various fields. But first, let’s discuss what scientific research is, its importance, types, and steps.

Researchers always seek accurate information and clear facts in all fields. They carry out this process according to a clear methodology for studying contemporary issues. They rely on scientific research as an objective tool to investigate and refute evidences. The first to use the scientific research method was psychologists and sociologists in the nineteenth century. It is recalled that the psychologist Ernest Weber was the first to try to measure specific models of human behavior in the 1940s of the century.

Definition of scientific research:

There are many different definitions of scientific research. It is defined as the systematic method that follows a number of successive steps, from knowledge of the problem to analysis, data collection and documentation, in order to extract a number of solutions derived from analysis, comparison and statistics.

It is also defined as an organized and systematic investigative process with the aim of ascertaining the truth of facts or proving new facts. Provided that scientific methods are followed while conducting the scientific research and preparing its reports and results.

It is also considered by some to be a systematic study built to meet lack of knowledge,  and to link disparate or mixed concepts, or to achieve a new knowledge derived from scientific research procedures and results.

The importance of scientific research:

The importance of scientific research is reflected in many of the skills acquired by researchers while working on their research. It also shows great effects on societies that in turn benefit greatly from the results of such research. Therefore, we can summarize the importance of scientific research in the following points:

1- To develop the scientific research skills of researchers, and help them identify the best scientific means to access accurate scientific information and avoid randomization.

2- To increase the knowledge of researchers and expand their knowledge. This is one of the importance of research at an individual level, where a researcher can access new information in the area of their specialization.

3- To develop the sectors of the state. This can directly reflect on the general public, as the latest technologies can be provided in various areas of life making it easier for them to perform their daily activities.

4- To develop industries through the use of modern technologies, which affects the rate of production and eliminates the use of traditional means of manufacturing.

5- To check and review previous scientific studies on similar scientific subjects. New researchers can then clarify the validity of the results of these previous researches.

Types of scientific research:

Scientific research can divided according to:

1- Purpose of research.

2- Research method.

First: Division by purpose of research:

Theoretical research: This is a scientific research that produces a set of theoretically proven laws and theories. It contributes to the growth of knowledge, serves the studies, and establishes a documented ground for applied science.

Applied Research: Researches that concerned with the practical side and the application of available knowledge to discover more accurate facts, solve various problems, and develop methods of work to achieve higher levels of production. There are a lot of new techniques that could be used in this researches such as virtual labs.

Second: Division by method:

Descriptive research: It aims to describe the various phenomena, monitor the spatial and temporal conditions, and try to reach a clear understanding of these phenomena. This type includes several methods, such as: observation, personal interview, and paper or electronic survey tests.

Historical research: It has the same descriptive form, but it is limited to the events that have already occurred. It aims to document the past and analyse its events in order to provide new methods for avoiding past pitfalls and predict a better future.

Experimental research: This research is concerned with the analysis of problems and phenomena based on the experimental method through observation, development of hypotheses, and checking the details for authenticity to verify their validity. In this type, researchers adjusts all the variables and control them in terms of serving the content of their research. This is perhaps what distinguishes experimental research from other types.

Scientific writing steps:

1- Identify and select the research title.

2- Introduction to research.

3- Clarify the problem.

4- Research questions.

5- Write the research objectives.

6- Clarify the importance of the research.

7- Methodology of the study.

8- Study tools.

9- Research plan.

10- References.
