Science and the Scientific Process – Quick Reference Notes

Definition of Science

  • Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.
  • It is a systematic and logical approach to understanding phenomena, involving observing, asking questions, and using evidence to build, test, and refine explanations.

Goals and Importance of Science

  • Explanation: understand how and why things work
  • Prediction: anticipate outcomes under certain conditions
  • Control/Application: improve quality of life via technology, medicine, environment, etc.
  • Continuous Revision: knowledge is open to further investigation and revision

Scientific Method

  • Foundation of scientific inquiry: conclusions based on logic, evidence, and reproducibility rather than guesswork or bias

Observation

  • Scientists note phenomena, patterns, or problems that spark curiosity
  • Examples of observation focus: patterns in political discussion during elections, differences between urban and rural communities
  • Research Spark: question why certain communities engage more in political discussions during elections

Formulating Research Questions

  • Formulate clear, researchable questions based on observations
  • Example Research Spark: Why do people in some communities engage actively in political discussions during elections, while others do not?
  • Research Questions (examples):
    • 1) What social factors influence the frequency of political discussions among community members during election periods?
    • 2) How do community characteristics (urban vs rural, socioeconomics, education) affect political engagement in public spaces during elections?
    • 3) To what extent do media exposure and access to information shape participation in political discussions during elections?
    • 4) What role do local leaders and social networks play in stimulating political conversations during campaigns?
    • 5) How does perceived political efficacy affect willingness to join discussions in various neighborhoods during elections?
    • 6) Are there differences in topics or tone of discussions between highly engaged vs. less engaged communities during elections?

Background Research

  • Review existing knowledge to inform the investigation and avoid repetition
  • Key ideas:
    • Social capital and community attachments: networks of relationships, trust, and reciprocity influence political participation; stronger social bonds encourage more discussions and engagement.
    • Political efficacy and interest: belief in influencing government and genuine interest in politics predict participation; internal (self-efficacy) and external efficacy both matter; interest can be a stronger motivator than efficacy alone.

Hypotheses

  • If higher social capital, then greater engagement in political discussions during elections.
  • If higher political efficacy, then more active participation in political discussions.
  • If greater access to political information (media), then higher levels of political discussion and engagement.
  • If active local leaders/influencers encourage discourse, then higher participation in election-related discussions.

Variables (Experimental/Data Collection)

  • Independent Variables (IVs): factors that influence engagement
    • Level of social capital (strength of networks, trust among community members)
    • Political efficacy (belief in ability to affect political processes)
    • Access to political information (media exposure, internet availability)
    • Presence of community leadership encouraging discussions
    • Socioeconomic status (education, income)
    • Cultural norms regarding political participation
    • Urban versus rural setting
  • Dependent Variable (DV): outcome to measure
    • Level of active engagement in political discussions during elections, operationalized as:
    • Frequency of participating in political conversations in public or private settings
    • Willingness to express political opinions openly
    • Participation in election-related discussions on social media or community forums

Data Collection

  • Use survey/questionnaire to answer the research objectives

Analysis

  • Organize and interpret data using graphs, tables, and statistics
  • Determine whether results support or refute the hypotheses
  • Correlations observed:
    • Between political efficacy and frequency of political discussion: r=+0.62r = +0.62
    • Between social capital and political engagement: r=+0.55r = +0.55
    • Between media exposure and engagement: r=+0.48r = +0.48

Conclusion

  • Findings: communities with stronger social networks, higher political efficacy, greater access to information, and active community leadership are more likely to engage in political discussions during elections.
  • Implications: social capital and information accessibility foster civic participation; urban areas tend to show higher engagement, while rural areas may need targeted communication infrastructure and mobilization efforts.

Foundations of Scientific Inquiry

  • Key components: Theory, Logic, Data, Observation, Data Collection, Data Analysis
  • Movement: Theory + Data collection leads to Data Analysis; both feed back into Theory

Theoretical and Empirical Plan (Fig. 1)

  • Theoretical Plane:
    • Construct A, Construct B, Proposition, Independent Variable, Dependent Variable, Hypothesis
  • Empirical Plane:
    • Data collection, Analysis, Observations, Hypothesis testing

Theoretical and Empirical Plan – Aspects of the Scientific Enterprise

  • Theoretical Plane vs Empirical Plane: constructs, propositions, hypotheses mapped to data collection and analysis

Guiding Principles for Scientific Inquiry (National Academies, 2002)

  • Principle 1: Pose significant questions that can be investigated empirically
    • Nature of questions: science proceeds by posing significant questions with potentially multiple answers
    • Manner of posing: questions must be posed so that they lead to testable hypotheses
    • Significance: a question’s significance is grounded in prior research, theory, and policy relevance
    • Characteristics of significant questions: empirically investigable, relevant/important, focused/clear, feasible
  • Principle 2: Link research to theory
    • Research should be connected to established theories or frameworks relevant to the problem
  • Principle 3: Use methods that permit direct investigation of the research
    • Methods are the design for data collection, measurement, and analysis; the question drives method choice
    • Methods should allow direct observation, measurement, or experimentation
    • Can include experimental, observational, correlational, or mixed methods
  • Principle 4: Provide coherent, explicit chain of reasoning
    • Build transparent, step-by-step explanations showing how data support conclusions
  • Principle 5: Replicate and generalize across studies
    • Replication increases reliability; generalization tests broader applicability
  • Principle 6: Disclose research to encourage critique and critique/peer review
    • Transparency of methods, data, analyses, and conclusions
    • Promotes accountability, replication, and scientific dialogue
