Tpack

Main ideas / concepts conveyed

• Why this topic matters now (2024 onward):

  • Major changes in education are expected starting in 2024, especially in:
    • how AI will be applied in classrooms
    • how administrative work will be reduced
  • Although the lecture focuses on using generative AI effectively, the speaker stresses that teaching technology and AI tools evolve quickly, so educators must keep adapting.

• Purpose of the lecture: “How to Effectively Utilize Generative AI”

  • The goal is not simply “use AI,” but use it with the right teaching purpose.
  • The lecture helps learners/teachers develop:
    • the mindset and teacher perspective required
    • an understanding of the difference between a class that uses TPACK well versus one that does not.

• Core framework introduced: TPACK (Technological Pedagogical Content Knowledge)

  • TPACK is presented as a framework for the knowledge teachers need to use AI and digital tools effectively.
  • The speaker emphasizes that the three knowledge domains must intersect to create effective learning design.

Methodology / instructional structure (detailed)

1) Use the TPACK framework when designing lessons with AI/digital tools

When planning a class, consider four components:

• CK (Content Knowledge): knowledge of what to teach
• PK (Pedagogical Knowledge): knowledge of how to teach so students learn
• TK (Technological Knowledge): knowledge of which tools and how to use them (AI/digital tools)
• Context: the surrounding learning environment/conditions (implied around the three domains)

---

2) Define each knowledge domain (with examples)

CK — Content Knowledge (what to teach)

• Deep understanding of the subject matter, for example:
  • calculus for math
  • literature for Korean
  • grammar/speaking theory for English
  • nursing topics like EMS for nursing
• CK is framed as foundational: without content knowledge, teaching methods or technology have no real meaning.

PK — Pedagogical Knowledge (how to teach)

• Teaching methods and learning design, such as:
  • how to ask questions
  • designing cooperative learning
  • preventing “free riders”
  • providing immediate feedback
  • presenting learning objectives
  • conducting process evaluation
  • grading
• Examples of approaches mentioned:
  • PBL (problem/project-based learning)
  • flipped learning ideas (e.g., “watch videos at home, discuss in class”)
  • peer evaluation
  • formative/process evaluation

TK — Technological Knowledge (how to teach with technology)

• Ability to select and use digital tools and AI in education, such as:
  • GPT for generating/drawing/assisting
  • Padlet for online collaboration
  • Canvas/Cambar for preparing materials
  • other AI-enabled learning management/data systems
• Key warning: TK changes the fastest.
  • Tools/features may disappear or be replaced rapidly by large corporations.
  • The speaker gives an example of a website (Loveable) that became obsolete after Google changes and shifts in adoption.

3) Recognize the intersection products of TPACK

• PCK (Pedagogical Content Knowledge)

  • Intersection of PK + CK
  • Means teaching methods matched to the subject so students can learn effectively.

• TCK (Technological Content Knowledge)

  • Intersection of TK + CK
  • Means expressing content using technology effectively (e.g., AI-generated visualization to improve understanding).

• TPK (Technological Pedagogical Knowledge)

  • Intersection of TK + PK
  • Means using technology in ways that support specific teaching approaches (e.g., Padlet enabling real-time simultaneous student posting → more active discussion).

• TPACK (full integration)

  • Using technology + pedagogy + content together in a planned way.
  • Summary given by the speaker: Use curriculum content, learner characteristics, pedagogy knowledge, and technology knowledge to decide what tools to use and how to structure the lesson.

4) Compare three “levels” of using tech in class (example scenario)

Using an example of a writing/English-like class to show differences in learning outcomes:

Case A: Only TK

• Students mainly prompt GPT to write for them.
• Result:
  • students may learn to use tools
  • but learning goals and thinking processes are bypassed
• Implication:
  • technology use becomes superficial (tool use without learning transfer)

Case B: Only CK + PK (no TK)

• Teacher teaches persuasive writing structure.
• Students write by hand.
• Teacher provides feedback later (e.g., after a week).
• Result:
  • delayed feedback disrupts learning flow
• The lecture references Ebbinghaus’s forgetting curve:
  • students forget a large portion quickly
  • so effectiveness/continuity drops

Case C: Full TPACK (CK + PK + TK integrated)

• Students write first drafts themselves.

• Then GPT is used for targeted help:

  • prompt GPT to identify logical weaknesses in student writing
  • have students evaluate/compare AI feedback (the speaker gives an example concept of students reviewing feedback critically)

• Caution:

  • AI can be wrong, so critical thinking should be part of the learning design
• Result:
  • students learn to use GPT while practicing reasoning, revision, and learning thinking processes

---

5) Practical “self-assessment” activity (embedded exercise)

Learners are asked to:

• check their status in CK, PK, TK
• record it in “Learning Transformation Notes” (or a similar learning note tool)
• then identify:
  • strengths
  • weaknesses
  • and how to develop gaps

Suggested improvement paths:

• CK: likely strengthened through major subject classes
• PK: learned through education/pedagogy courses and practice teaching
• TK: learned through children’s classes, teacher workshops, training sessions, or online courses (example mentioned: “TeacherVille”)

---

Lessons / takeaways emphasized

• Don’t treat AI tools as the lesson itself.
  • The key is the purpose, timing (when), and audience (to whom) you use the tool.
• TPACK integration is what makes technology educationally meaningful.
• TK changes quickly, so educators must continuously update and select tools that align with instructional goals.
• Students should do real thinking, not outsource work to AI.
• AI feedback must be treated as fallible, requiring student critical review.
• The speaker reflects as a first-time learner/teacher and encourages personal reflection on preparedness.
