This concise handbook leads prospective didactic researchers from project conception to thesis defense. It lays out early tasks, selecting a viable topic, framing a problem, scheduling work, then surveys qualitative, quantitative, and mixed-method designs tailored to educational inquiry. Practical chapters explain how to gather data through surveys, observations, interviews, and questionnaires, with tips on instrument design and ethical use. A dedicated writing section shows how to transform notes into polished prose, structure chapters, cite sources, and format the document. Final guidance covers creating clear visuals, managing appendices, and mastering the oral defense. Throughout, the guide stresses originality, methodological rigor, and relevance to teaching-learning contexts.
