Introduction

Research is a process of investigation or experimentation focused on the interpretation and discovery of facts or revision of current theories. Purpose of researches is to help increase our understanding and knowledge of a certain issue or topic [1]. Therefore, in order to keep going on the right way of the goal of research that produces deep understanding or new knowledge, we need research methodologies (research methods).

There are many research methods whose objectives and characteristics are quite different from others. Each research field often uses certain methodologies, but normally, researchers must survey what kind of methods suitable for their researches. A logical and reasonable methodology can guide researchers to   correct results, even new theories. Moreover, it helps the researchers save their time and other people can understand and position the researches easily.

I am a master student in Computer Science, so in this paper, I aim mainly at research methodologies in CS. In the remains of introduction, I present briefly what is scientific research in CS, steps of researching, family of research approaches, key methodologies, and qualities of researches through summarizing the content of "Research methods in Computer Science" class [2]. Furthermore, I give my unclear points during the course as problems that I need to work on more in order to understand clearly.
