Abstract

In educational research, identifying variables and determining data sources are essential components in designing a systematic and accurate study. Research variables refer to the elements that are observed and measured within a study. These variables can include student achievement, motivation, teaching strategies, or learning environment conditions. Generally, variables are categorized as independent, dependent, control, or moderator variables. The independent variable is the influencing factor, while the dependent variable is the outcome. Control variables are held constant to avoid interference, and moderator variables affect the strength or direction of the relationship. The process of identifying variables begins with formulating the research problem and objectives. By reviewing theoretical frameworks and previous studies, researchers can focus their investigation on measurable aspects. For instance, in a study about the effectiveness of online learning on student performance, the independent variable is online learning, while the dependent variable is student achievement. Beyond identifying variables, researchers must also determine the appropriate types of data sources. Data sources are generally divided into two categories: primary and secondary. Primary data are collected directly from research subjects, such as through interviews, observations, or questionnaires. Secondary data, on the other hand, are obtained from existing sources like documents, books, journals, or official reports. The choice of data source must align with the research approach—quantitative, qualitative, or mixed methods. In quantitative research, primary data such as test scores or survey responses are used to measure variables numerically. In qualitative research, in-depth interviews and observations are commonly used to explore meanings and context. Using both types of data in combination can enhance data validity through triangulation. Ultimately, researchers must ensure the validity and reliability of their data, while also maintaining ethical standards in data collection and reporting. By understanding how to identify variables and select appropriate data sources, educational research can yield credible findings that contribute meaningfully to educational theory and practice.

Abstract

The Society 5.0 era demands advancements in educational research to generate innovation and scientifically based solutions. However, the low quality of research is often caused by a lack of open, critical, and innovative thinking. Open-mindedness allows researchers to embrace new perspectives, critical thinking helps analyze issues in depth, and innovative thinking fosters the emergence of fresh ideas relevant to current developments. This study aims to examine the nature of educational research and its role in strengthening thinking skills to enhance the quality of scientific work. Using the library research method, this study analyzes the concepts, methodologies, and relevance of educational research in the digital era. The findings indicate that open, critical, and innovative thinking in research can improve the quality of education and support adaptation to global changes. Additionally, high-quality research serves as a foundation for more effective education policies. Strengthening thinking skills in educational research is essential to producing higher-quality scientific works that are relevant to the development of Society 5.0.

Abstract

Educational research requires a thorough understanding of population and sample concepts as the foundation for ensuring the validity and generalizability of findings. This article explores the fundamental differences between population and sample, the implications of their selection on research outcomes, and appropriate strategies for selecting a representative sample. By reviewing commonly used sampling approaches, such as probability and non-probability techniques, this paper highlights the importance of aligning the method with the research objectives and context. A clear understanding of these concepts is crucial for researchers to produce accurate, reliable, and contextually relevant educational data.
