What is science?

• Science is the systematic study of the natural world through observation, experimentation, analysis, and evidence-based explanation.
• The discipline tests ideas, builds knowledge, and revises explanations when new evidence changes existing understanding.
• Science provides methods for interpreting organisms, materials, environments, landscapes, societies, and the processes connecting them.

What are the main reasons for being active in the field of science?

• Science offers an intellectual framework for asking questions, testing explanations, and distinguishing evidence from unsupported assumptions.
• The field examines environmental processes such as ecosystems, climate change, biodiversity, geological activity, and interactions between people and nature.
• Scientific methods connect theory with practical investigation through experiments, observations, measurements, models, and systematic analysis.
• Scientific knowledge contributes to public discussions involving healthcare, technology, environmental management, materials, and social development.
• Research frequently crosses national and disciplinary boundaries because many scientific questions require shared data, facilities, methods, and expertise.

What are the main features of science?

Science investigates natural and social phenomena through organized observation, experimentation, analysis, and explanation, while keeping its findings open to testing, replication, and revision.

• Evidence-based inquiry: Scientific explanations depend on observable or measurable evidence gathered through systematic research rather than intuition, authority, or unsupported assumption.
• Objectivity: Scientific methods aim to limit personal bias through transparent procedures, standardized measurements, critical evaluation, and comparison with independently collected evidence.
• Repeatability: Researchers describe their methods clearly so others can repeat investigations, examine results, and determine whether findings remain consistent under similar conditions.
• Knowledge building: Science develops an expanding body of knowledge by connecting individual findings with established theories, models, measurements, and earlier observations.
• Continuous revision: Scientific understanding changes when new evidence, improved instruments, stronger methods, or alternative explanations reveal limitations in existing conclusions.

What are important sub-areas of science?

Science contains several broad branches that investigate different aspects of reality while sharing methods of systematic observation, logical analysis, modelling, and evidence-based explanation.

• Natural sciences: Physics, chemistry, biology, astronomy, geology, and ecology examine matter, energy, organisms, Earth systems, and processes in the physical universe.
• Social sciences: Psychology, sociology, anthropology, economics, and political science investigate human behaviour, institutions, cultures, societies, relationships, and collective decision-making.
• Formal sciences: Mathematics, logic, statistics, and computer science examine abstract structures, symbolic systems, algorithms, relationships, and rules of valid reasoning.
• Physical sciences: Physics and chemistry study forces, motion, energy, matter, substances, reactions, and the fundamental principles governing physical systems.
• Life sciences: Biology and related fields examine organisms, cells, heredity, evolution, physiology, ecosystems, and relationships among living forms.

What are key concepts in science?

Scientific investigation relies on concepts that organize research, connect evidence with explanations, and clarify how natural or social phenomena can be represented and understood.

• Scientific method: Research commonly progresses through observation, question formulation, hypothesis development, testing, analysis, interpretation, and communication of the resulting conclusions.
• Scientific theory: A theory provides a well-supported explanation that connects multiple observations and remains open to further testing or revision.
• Natural law: Scientific laws describe consistent relationships or patterns observed under defined conditions without necessarily explaining why those patterns occur.
• Scientific model: A model simplifies a system or process so researchers can represent relationships, test assumptions, make comparisons, or explore possible outcomes.
• Hypothesis: A hypothesis is a focused and testable proposed explanation that guides the collection, analysis, and evaluation of relevant evidence.

Who are influential figures in science?

Influential scientists have shaped the discipline by developing new theories, experimental methods, observations, or forms of evidence that changed established explanations of nature.

• Galileo Galilei: His astronomical observations and studies of motion strengthened experimental investigation

What is research design?

Further depth: what is research design as a discipline?

What are the main features of research design?

Research design establishes the logical structure of an investigation, connecting its question with appropriate procedures while considering validity, reliability, bias, ethics, participants, and available resources.

• Purposeful structure: Each design is selected according to the question being investigated and the kind of evidence required to address it effectively.
• Bias management: Study procedures are organized to reduce systematic distortion and support conclusions that remain consistent with the collected evidence.
• Ethical planning: Participant selection, informed involvement, data collection, and research procedures must be structured in accordance with relevant ethical responsibilities.
• Resource alignment: Time, funding, personnel, access, and practical constraints influence how an investigation can be organized without weakening its central purpose.

What are important sub-areas of research design?

Research design includes quantitative, qualitative, and mixed-methods approaches, each offering distinct ways to organize evidence around measurement, comparison, interpretation, experience, or contextual understanding.

• Experimental design: Researchers manipulate an independent variable and observe changes in a dependent variable to investigate possible cause-and-effect relationships.
• Survey research: Questionnaires or interviews collect structured information from a sample intended to represent a broader population or defined group.
• Quasi-experiments: These designs examine intervention effects when full experimental control or random assignment is unavailable or impractical.
• Case studies: A bounded individual, group, organization, event, or situation is examined intensively within its particular context.
• Ethnographic design: Researchers use observation and participation to examine the practices, meanings, and relationships of a culture or social group.
• Phenomenological research: Investigations focus on how individuals describe and interpret their lived experiences of a shared phenomenon.
• Mixed methods: Quantitative and qualitative evidence are combined to examine different dimensions of the same research question.

What are key concepts in research design?

Core concepts define what a study investigates, whose experiences or characteristics are represented, how evidence is produced, and how confidently its conclusions may be interpreted.

• Research question: The central question determines the study's focus and guides the selection of participants, variables, methods, and analytical procedures.
• Variables: Measured or analyzed characteristics allow researchers to examine patterns, differences, associations, and possible effects within a study.
• Variable roles: Experimental designs distinguish the manipulated independent variable from the dependent variable used to observe a possible effect.
• Validity: Validity concerns
