Main ideas / lessons conveyed

  • Purpose of “Show & Tell” at the Gyeongin National University of Education Science Gifted Education Center

    • An annual weekend event in early December
    • Each student presents research conducted independently
    • Presentations last about 5 minutes and use materials such as PPT
    • Framed as a “creative output competition”, not just an evaluation
    • Goal: build confidence as a presenter, progressively preparing students for skills used in academic conferences and papers

  • What “Show & Tell” means in science

    • Extends the childhood activity (“bring something, show it, explain it”) into science by sharing:
      • Why the student conducted the inquiry
      • How it was conducted (process)
      • What results were obtained (outcomes)
    • Compared with how scientists communicate research:
      • Oral presentations at conferences/publishing contexts
      • Poster presentations, with on-site interaction and Q&A
    • Claimed key value: sharing research supports feedback, refinement, collaboration, and accumulation of collective knowledge

  • How students should think about research topics

    • Start from genuine personal curiosity (not just what others expect)
    • Begin small if needed—“show and tell” doesn’t require a huge project
    • Keep scope specific and doable within the time limit
    • Check feasibility:
      • Can you do it with your available tools/materials?
      • Can you finish within your level/time constraints?

  • Safety and ethics

    • Research must be conducted safely (avoid dangerous experiments such as home explosions/toxicity tests)
    • Follow ethical considerations, especially when working with living organisms
    • Safety and ethics are treated as core social/scientific responsibilities

  • Record-keeping and preparation

    • Keep investigation notes (notebook or digital file)
    • Save data, photos, and the research process so you can present later
    • Present not only results, but also the necessary process steps (don’t rely on trust)

  • How to structure the PowerPoint

    • Use visuals and text so the audience can clearly understand
    • Don’t simply copy-paste—reorganize into your own presentation
    • Include:
      • Motivation/necessity for the inquiry
      • Purpose and the research question/problem
      • Theoretical background/scientific principles
      • The method (especially detailed for experiments/observations)
      • Where/how it was done
      • Results, conclusions, and reflections (students may include feelings unlike typical scientist talks)

  • Examples by course level

    • Mentions course/resource book production (2022–2025) and advancement/next-year planning for 2026
    • Provides sample topics across ages/levels, such as:
      • Paper airplanes
      • Freezing related to salinity
      • Temperature effects when raising chicks
      • Noise-canceling
      • Magnets
      • Interests related to aircraft/climate

Methodology / instruction list (detailed)

1) Timeline and event format (Show & Tell specifics)

  • Present during the weekend Show & Tell session in early December each year.
  • Each student presents:
    • Their independently conducted research from the past year (self-directed inquiry)
    • Using PPT or presentation materials
  • Presentation length: ~5 minutes (matching the center’s format)

2) Choose your inquiry topic (step-by-step guidance)

  • Step 1: Find a topic
    • Prefer a topic you’re truly curious about in daily life
    • Even a small question can start meaningful inquiry
  • Step 2: Start from curiosity, narrow the problem
    • If the curiosity is too broad, lower the level and focus on something manageable
  • Step 3: Keep idea notes
    • Write down questions/ideas immediately while reading, watching, or studying
  • Step 4: Generate ideas using sources
    • Use the internet with keywords tied to your interests
    • Review what other students did (science fairs, middle/high school competitions)
    • Optionally use generative AI to brainstorm (as conversation, not blind copying)
    • Consult with parents while ensuring the direction stays your own

3) Check feasibility before committing

  • Ensure the investigation is specific and can be completed in the available timeframe
  • Confirm it matches your level:
    • Avoid requiring graduate-school-level equipment you can’t access
  • Make sure materials can be obtained and handled safely at student level

4) Safety and ethics checklist

  • Safety
    • Do not conduct dangerous experiments (e.g., explosions, toxicity tests) at home
  • Ethics
    • Be mindful when research involves living organisms (e.g., rules for dissection)
    • Consider both handling-life ethics and broader social ethics

5) Conduct the inquiry and maintain documentation

  • Keep proper investigation notes throughout:
    • Notebook or digital file—either is fine, but recording must be continuous
  • Save and organize:
    • Collected data
    • Photos of the research process and outcomes
    • Anything needed to justify your findings later
  • Record evolving thinking:
    • Questions, interpretations, and observations (e.g., “why is this happening?”)

6) Build the PowerPoint presentation (required content)

  • Main goal: clear communication to the audience
  • Include:
    • Motivation/necessity
    • Purpose and the research problem/question
    • Scientific principles/theory
    • Method details
      • How/where the investigation was done
      • Experimental/observational procedures
    • Results
    • Conclusions
    • Reflections
  • Formatting guidance:
    • Use text and images effectively
    • Improve readability for a 5-minute talk
    • Don’t scrape/paste—reorganize in your own words and add necessary diagrams/photos

7) Possible kinds of scientific inquiry (six categories)

  1. Observational inquiry
    • Observe phenomena/objects using senses and precise tools (microscope/telescope/thermometer)
    • Examples: seasonal plant changes, moon shape changes, leaf network structures
  2. Experimental inquiry
    • Test hypotheses by controlling variables and measuring/analyzing outcomes
    • Examples: enzyme reaction vs temperature, photosynthesis vs light intensity
  3. Investigative inquiry (research/data collection)
    • Gather existing information/data from internet/books/papers/journals/databases
    • Includes:
      • Big data analysis (e.g., weather/fine dust data from institutions)
      • Document/status surveys
      • Field trips to collect/analyze information
  4. Rearing (cultivation) inquiry
    • Raise plants/animals; observe growth, behavior, and life cycles; record data
    • Examples: bean life cycle, raising rhinoceros beetles/chicks
  5. Invention/making (engineering) inquiry
    • Create prototypes/models/systems to solve everyday problems
    • Examples: optimize paper airplane design, insulating tumbler, coding-based solutions
  6. Model/simulation inquiry
    • Use simulations when real-world observation/experimentation is difficult
    • Examples: universe/composition simulations, geological change models, molecular simulations

8) Inquiry process types (three representative methods)

  1. Inductive method
    • Collect observations and derive general patterns/laws
    • Often used in observational inquiry
  2. Hypothetical-deductive method
    • Form a hypothesis, then verify via controlled experiments
    • Control variables; interpret results; revise the hypothesis if needed
  3. Engineering design method
    • Identify a real-world problem → generate ideas using scientific principles → design/create prototypes → test/verify → improve
    • Define a solvable problem within time/material limits and iterate through prototyping

9) Decide which inquiry method fits your topic

  • Match your topic to one (or more) inquiry categories:
    • observational / experimental / investigative / rearing / invention / model-simulation
  • Then match with a corresponding inquiry process:
    • inductive / hypothetical-deductive / engineering design
