Steps of Scientific Method by Galileo
The first researcher to apply a scientific approach with a series of well-defined steps was...
Galileo Galilei (1564-1624)
Find a problem or event that you want to explain
Observation
Is a variable that trouhgout the experiment stays fixed the whole time
Controlled variable
Object of study?
The world and natural phenomena
Object of study?
The human being, the social world and its interactions
Implies a detailed description of the object to be investigated or of the aspect to be solved
Observation
Define the specific questions of the problem to investigate
Statement of the problem
This variable does not depend on something to be, the researcher manipulates it experimentally
Independent variable
Method used?
Mainly quantitative, experimental and supported byformal sciences, such as mathemathics
Methods used?
Quantitative, qualitative and mixed
Provisional explanation of the phenomenon
Formulation of an Explanatory Hypothesis
Analyze the consequences of possible explanations
Hypothesis
It focuses on the particular characteristics and condition of the object studied
Qualitative
Steps and stages?
Observation, Statement of the problem, Hypothesis, Experimentation, Analysis and conclusions
Steps and stages?
Exploration, Planning, Execution, Evaluation, Communication
It served to substantiate the relationship of this hypothesis with the rest of the scientific knowledge existing up to this time
Deduction
Design experiments to confirm or refute possible explanations, and obtain results
Experimentation
It focuses on statistics and numerical data obtained from the observation of study
Quantitative
Approaches or types?
Exploration and field practices, Description of the phenomena, Documentary inquiry
Approaches or types?
Historical, Comparative, Critical-rational
Reproduces the phenomenon and the conditions in which specific changes occur to control the way they happen, carefully analyzing the events, taking measurements and better understanding the effects of certain phenomena
Experimentation
Make judgments based on the study of the results
Analysis and conclusions
This depends on something that makes it vary, one tries to change this variable by manipulating the independent variable
Controlled variable
