The scientific approach is no longer limited to the sequence of observation-hypothesis-experimentation-conclusion found in most textbooks. Since the adoption in 2021 of the UNESCO Recommendation on Open Science, the scope of this approach includes data management, protocol traceability, and conditions for reusing results. A practical PDF guide that claims to cover the topic without addressing these dimensions remains incomplete.
Registered reports and pre-registered protocols: a methodological turning point
Most methodological sheets describe the scientific approach as a linear sequence of steps. This presentation conceals a documented problem: the temptation to modify hypotheses or protocols after observing results.
Registered reports address this difficulty. The principle is to submit the research question, hypotheses, and experimental protocol to peer review before data collection. The French open science strategy 2026-2033, published on September 16, 2026, by the Ministry of Higher Education, Research, and Space, positions this format among the levers of reproducibility.
A PDF guide that details the steps of the scientific approach in PDF would benefit from integrating this dimension from the protocol design phase, not just at the final writing stage.
Pre-registration does not eliminate all flexibility. It requires a clear distinction between planned (confirmatory) analyses and analyses added afterward (exploratory). This distinction, rarely explained in traditional methodological sheets, changes how results are interpreted.
Scientific approach and data management: what the 2021 UNESCO Recommendation covers
The UNESCO Recommendation on Open Science, adopted in 2021, expands the scope of the scientific approach to six components:
- Open access scientific publications, including preprints and research reports
- Research data, their documentation, and metadata, with explicit reuse conditions
- Software and source code used to produce and analyze results
- Open educational resources and shared infrastructures
- Citizen participation in research processes
Planning data management from the project’s design is no longer an optional good practice. It is an institutional expectation in most European and French funding programs.
For a student or young researcher consulting a methodological PDF guide, the concrete consequence is as follows: the scientific approach does not stop at publication. It includes depositing datasets in a repository, drafting a management plan, and choosing a dissemination license.
Reproducibility in the humanities and psychology: the limits of the classical experimental model
The classical scheme (observation, hypothesis, experimentation, results, conclusion) works well in physics or chemistry. Its application in the humanities, psychology, or education sciences poses specific difficulties that PDF guides rarely address.
In psychology, the results of an experiment often depend on the cultural and temporal context in which it was conducted. Reproducing a protocol exactly in another country or ten years later can yield different results, even if the initial protocol is sound. Field feedback varies on this point across disciplines.
What the transparency of the editorial process changes
The French open science strategy 2026-2033 emphasizes an aspect often absent from methodological manuals: the transparency of peer review. This includes reporting problematic publications and tracking article retractions.
A practical guide to the scientific approach should therefore teach how to check the editorial history of a source. Knowing whether an article has undergone corrections or retractions is part of the bibliographic exploration step, just like reading the abstract or methodology.
Building a useful PDF guide: three criteria for methodological quality
The majority of available online methodological sheets follow the same breakdown into four or five steps. This format has the merit of clarity, but it produces interchangeable documents. For a PDF guide to provide real value, three criteria should be checked.
The first concerns the distinction between hypothetico-deductive and inductive approaches. A guide that mentions only the former ignores a significant part of research in social sciences, where one often starts from data to build a theory, not the other way around.
The second criterion pertains to the presence of disciplinary examples. A protocol in molecular biology has nothing to do with a field survey in education sciences. Véronique Barthélémy, in her work on the stages of the research process, describes seven stages organized into three acts (disruption, construction, observation), a breakdown more suited to the humanities than the classical school scheme.
The third criterion, most often absent, concerns the documentation of the protocol to allow for reuse. A guide that explains how to formulate a hypothesis but not how to archive data or describe variables in a standardized manner remains incomplete in light of current requirements.
Scientific approach in school and academic contexts
The methodological sheets intended for middle school students (observation, hypothesis, experiment, conclusion) serve a legitimate pedagogical role. However, transposing them as they are into a master’s thesis or doctoral project creates a mismatch. Methodological rules in academic research require explicit problematization, a well-argued theoretical framework, and an analysis of potential biases.
The available data do not allow for concluding that a single guide format covers all levels. A PDF intended for a university audience should at a minimum address the starting question, bibliographic exploration, the problem statement, the construction of the analysis model, observation, information analysis, and conclusions, which are the seven steps described in research work in education sciences.
The scientific approach is evolving faster than the documents that describe it. A PDF guide downloaded five years ago probably does not mention registered reports, open data management, or checking the editorial history of sources. Checking the publication date of the document remains the first methodological reflex to adopt.
