Introduction to Science, Technology, and Society

Learning Objectives

  • Define science, scientific method, technology, and society.
  • Differentiate science from technology and explain their relationship.
  • Describe the interaction among science, technology, and society.

Concept of Science

  • Etymological Origin:

    • The word science originates from the Latin term scientia, which translates to "knowledge."

  • Broad Definition:

    • In its broadest sense, science refers to a systematic way of developing knowledge about the natural world and, in certain contexts, the social world through observation, investigation, evidence, reasoning, and communication.

  • Dual Nature of Science:

    • Science serves a dual function as both:
    • A structured body of knowledge regarding the natural world.
    • A process of inquiry utilized to develop and evaluate knowledge.
    • Example (Physics): Physics contains a body of knowledge surrounding matter, energy, motion, and forces. Simultaneously, physics represents a process through which scientists formulate questions, conduct systematic investigations, construct theoretical models, test explanations, and evaluate empirical evidence.

  • Characteristics of Science:

    • Empirical: Scientific knowledge is grounded directly in observations or evidence obtained from the physical world.
    • Systematic: Scientific investigations follow structured and organized procedures rather than relying solely on intuition, guessing, or speculation.
    • Evidence-based: Scientific claims must always be supported by appropriate, verifiable evidence.
    • Testable: Scientific explanations should, whenever possible, be capable of being tested against observational or experimental evidence.
    • Tentative: Scientific knowledge is not static; it can change or be revised when new and stronger evidence becomes available.
    • Communal: Scientific knowledge is open to being communicated, examined, criticized, replicated, and extended by the broader scientific community.
    • Self-correcting: Errors, oversights, and limitations in scientific knowledge are identified and corrected through ongoing investigation, critical evaluation, and the cumulative accumulation of evidence.

Scientific Method and Inquiry

  • Definition:
    • The scientific method is a systematic approach used to investigate questions, obtain evidence, develop explanatory models, and test predictions.

Major Components of Scientific Inquiry

  • Major Components of Scientific Inquiry:

    • 1. Observation: Noticing and describing phenomena in the natural world using the senses or observational instruments.
    • 2. Question: Asking a clear, precise, and specific question about what was observed.
    • 3. Hypothesis: Proposing a testable, possible explanation or answer to the formulated question.
    • 4. Investigation / Experimentation: Testing the hypothesis by collecting empirical data through carefully planned procedures.
    • 5. Data Collection: Systematically recording observations and measurements.
    • 6. Data Analysis: Organizing and analyzing collected data to identify underlying patterns, trends, or correlations.
    • 7. Conclusion: Drawing a conclusion grounded in data analysis to accept, reject, or modify the initial hypothesis.
    • 8. Communication: Sharing investigation results and conclusions with others through reports, presentations, or academic publications.

  • Iterative and Dynamic Process:

    • Scientific inquiry is inherently iterative; new questions frequently arise from drawn conclusions, leading to further rounds of inquiry.
    • Real scientific research does not always strictly follow these steps in a rigid, linear sequence. Scientists regularly move back and forth among questioning, observation, experimentation, modeling, data analysis, and explanation.

Concept of Technology

  • Misconceptions vs. Broad Definition:

    • Technology is often narrowly misunderstood as referring only to electronic devices such as smartphones, computers, and robots.
    • In a broader, complete sense, technology refers to the application of knowledge, skills, methods, tools, and techniques to solve practical problems, accomplish tasks, or satisfy human needs and goals.

  • Scope and Components of Technology:

    • Technology encompasses a wide variety of artifacts, knowledge, and practices, including:
    • Tools
    • Machines
    • Instruments
    • Processes
    • Techniques
    • Systems
    • Materials
    • Software
    • Methods of organizing human activities

  • Historical Context and Examples:

    • Technology existed long before the invention of modern computers or the Internet.
    • Diverse historical and modern examples of technology include:
    • A primitive stone tool
    • An agricultural technique
    • The printing press
    • An electric motor
    • A modern smartphone

Concept of Society

  • Definition:

    • Society refers to an organized group of individuals who interact with one another and share common institutions, systems, social practices, values, norms, and organizational structures.

  • Constituent Social Structures:

    • Society is comprised of various interacting structures, such as:
    • Families
    • Schools
    • Governments
    • Economies
    • Religious organizations
    • Industries
    • Scientific institutions
    • Media
    • Communities
    • Other social organizations

  • Interaction Among Science, Technology, and Society:

    • Science and technology (S&T) are developed, modified, and utilized directly within social contexts.
    • Technological development is never determined by scientific capability alone.
    • Example (Medical Technology): The development and adoption of a new medical technology depends on multiple social factors, including:
    • Government regulations and policy
    • Available funding and economic resources
    • Identified healthcare needs
    • Cultural beliefs and ethical standards
    • Public acceptance
