Phương pháp luận và phương pháp nghiên cứu: từ triết lý khoa học đến thiết kế nghiên cứu

Scientific research is fundamental to advancing knowledge, with its quality and credibility depending not only on novelty but also on the scientific integrity of its process. Research methodology and research methods are core to how scholars conceptualize, design, and validate findings, ensuring objectivity, reliability, validity, and replicability. A common challenge, particularly among students and early-career researchers, is the superficial understanding or confusion between these critical concepts. This often results in research designs that lack clear philosophical direction, theoretical depth, and logical coherence, undermining the persuasiveness and impact of scholarly work. This article aims to provide a systematic framework to address this gap.

Researchers, postgraduate students, and early-career academics in social sciences, education, and related fields, particularly those seeking to deepen their understanding of research methodology and methods.

This article critically examines the distinct yet interconnected roles of research methodology and research methods, arguing that their rigorous application is crucial for the quality and credibility of scientific inquiry. It begins by clarifying these two concepts, highlighting that methodology represents the philosophical and theoretical underpinnings guiding research decisions, whereas research methods constitute the specific tools and procedures for data collection and analysis. The paper emphasizes the dialectical relationship where philosophical paradigms inform methodological approaches, which in turn dictate the choice of research methods. Key components of methodology, such as research philosophy (e.g., positivism, interpretivism, pragmatism, critical realism, and especially Marxist-Leninist philosophy in the Vietnamese context) and research approaches (deductive, inductive, abductive), are meticulously discussed. Furthermore, it delves into practical aspects of research methods, including research design (quantitative, qualitative, mixed methods), population and sampling strategies, data collection tools, and data analysis techniques. The article underscores the importance of ensuring reliability, validity, and ethical integrity throughout the research process. By offering a comprehensive and systematic guiding framework, it aims to empower researchers, particularly in social sciences, to construct robust and logically coherent research projects. The implications extend to enhancing the academic rigor, trustworthiness, and societal relevance of scholarly contributions, ultimately fostering a deeper methodological understanding.
