What is Research

Research is a systematic inquiry to describe, explain, predict and control the observed phenomenon. Research involves inductive and deductive methods (Babbie, 1998). Inductive methods analyze the observed phenomenon and identify the general principles, structures, or processes underlying the phenomenon observed; deductive methods verify the hypothesized principles through observations. The purposes are different: one is to develop explanations, and the other is to test the validity of the explanations.

One thing that we have to pay attention to research is that the heart of the research is not on statistics, but the thinking behind the research. How we really want to find out, how we build arguments about ideas and concepts, and what evidence that we can support to persuade people to accept our arguments.

Gall, Borg and Gall (1996) proposed four types of knowledge that research contributed to education as follows:

  1. Description: Results of research can describe natural or social phenomenon, such as its form, structure, activity, change over time, relationship to other phenomena. The descriptive function of research relies on instrumentation for measurement and observations. The descriptive research results in our understanding of what happened. It sometimes produces statistical information about aspects of education.
  2. Prediction: Prediction research is intended to predict a phenomenon that will occur at time Y from information at an earlier time X. In educational research, researchers have been engaged in:
    1. Acquiring knowledge about factors that predict students’ success in school and in the world of work
    1. Identifying students who are likely to be unsuccessful so that prevention programs can be instituted.
  3. Improvement: This type of research is mainly concerned with the effectiveness of intervention. The research approach include experimental design and evaluation research.
  4. Explanation: This type research subsumes the other three: if the researchers are able to explain an educational phenomenon, it means that they can describe, can predict its consequences, and know how to intervene to change those consequences.

What are the purposes of research?
Patton (1990) pointed out the importance of identifying the purpose in a research process. He classified four types of research based on different purposes:

  1. Basic Research: The purpose of this research is to understand and explain, i.e. the research is interested in formulating and testing theoretical construct and propositions that ideally generalize across time and space. This type of research takes the form of a theory that explains the phenomenon under investigation to give its contribution to knowledge. This research is more descriptive in nature exploring what, why and how questions.
  2. Applied Research: The purpose of this research is to help people understand the nature of human problems so that human beings can more effectively control their environment. In other words, this type of research pursues potential solutions to human and societal problems. This research is more prescriptive in nature, focusing on how questions.
  3. Evaluation Research (summative and formative): Evaluation research studies the processes and outcomes aimed at attempted solution. The purpose of formative research is to improve human intervention within specific conditions, such as activities, time, and groups of people; the purpose of summative evaluation is to judge the effectiveness of a program, policy, or product.
  4. Action Research: Action research aims at solving specific problems within a program, organization, or community. Patton (1990) described that design and data collection in action research tend to be more informal, and the people in the situation are directly involved in gathering information and studying themselves.

What is the research process?
Gall, Borg, and Gall (1996) described the following stages of conducting a research study:

  1. Identify a significant research problem: in this stage, find out the research questions that are significant and feasible to study.
  2. Prepare a research proposal: a research proposal usually consists of the sections including introductory, literature review, research design, research method, data analysis and protection of human subject section, and timeline.
  3. Conduct a pilot study: the purpose is to develop and try out data-collection methods and other procedures.
  4. Conduct a main study
  5. Prepare a report

Gall, Borg, and Gall (1996) also explained that these five stages may overlap or occur in a different order depending the nature of the study. Qualitative studies which involve emergent research design may gather and analyze some data before developing the proposal, or a pilot study can be done before writing a research proposal or not at all.

Anglin, Ross, and Morrison (1995) took a closer look at the stages of identifying a research problem and preparing the research proposal. They advised a sequence of planning steps:

Select a Topic
Research requires commitment. As a researcher, you want to make sure you are doing something that you have a great interest in doing.
Identify the Research Problem
Based on your own understanding and interest of the topic, think about what issues can be explored? Sometimes, a research problem cannot be immediately identified. But, through reviewing the existing literature and having continuous discourse with peers and scholars, the research problem will start take its shape.
Conduct a Literature Search
Reviewing literature has two major purposes: one is to build up the researcher’s knowledge base of the topic under exploration for a deeper understanding, and the other is to ensure the significance of the research. The researcher needs to make sure how the research will be able to contribute to the knowledge in the related field compared with the existing research literature.
State the Research Question
The research problem will evolve during your pursuing knowledge base through reviewing literature and discourse with peers and scholars. To specify what questions your research study want to answer helps to provide the basis of planning other parts of your study, e.g. the research design, the methods for data collection and analysis.   Determine the Research Design In the intention of the research study is to verify a causal relationship between certain variables, use an experimental design; if the intention of the research study is to find out how variables relate to one another, use a correlational design; if the intention of the research study is to describe and understand a particular social condition/pattern and meaning of a social experience, conduct a qualitative study. Determine Methods Three major elements in the research study need to be considered: participants, materials, and instruments. Participants: It concerns whom to study. For experimental studies, the researcher needs to consider statistical sampling to make sure that sample is representative of the population, e.g. techniques of random sampling and stratified sampling. For qualitative research, purposeful sampling is the major principle. The selection of individuals, groups, or cases depends on how the characteristics, or properties of the individuals, groups, or cases will best inform the researcher with the focus of what is under investigation. Materials and Instrumentation: For experimental research, operationalization of the variables is the focus, i.e. what are different treatment conditions, and how to measure the dependent variables. The researcher has to consider issues about the reliability (the consistency of the test), and validity (whether the test is testing what is meant to test) of the measurement. The design of the experimental conditions has taken the threats of the internal and external validity into account. The researcher wants to make sure that the establishing of the causal relationship is not influenced by other factors than the controlling factors, and the researcher needs to consider to what extent the results of the research can be generalized to the population beyond the sample under study. For qualitative research, the issues are the sources of data, where the researcher can find the information and what methods the researcher can use to get the information. Qualitative research usually focuses on the verbal information gathered from the interviews, observations, documents or cultural artifacts. The very distinctive feature about the qualitative research is that the researcher is part of the instrument. The recognition of this researcher’s subjective interpretation of the information yields the process of triangulation, which emphasizes use of multiple sources, methods, investigators, and theories to ensure the credibility of the research. Procedures: A procedural planning of how to get approval from IRB, how to get entry to research participants or to the field, how to implement the experimental treatment or to schedule observations and interviews, and how to prepare for write-up. A general outline of the process and a timeline will facilitate the research progress.   Identify Analysis Procedures Different research questions and different research designs entail different analysis method to take. Experimental design employs statistical analysis to give statistical descriptions of the groups in terms of different independent variables and dependent variables, and to determine the significance of the differences whether the dependent variables are caused by the independent variables. On the other hand, qualitative design employs semantic analysis to identify themes, categories, processes, and patterns of an observed phenomenon, and provides rich descriptions of the phenomenon in order to develop a deeper understanding of human systems.   References: Anglin, G.
