Knowa's Ark: A Reflection
Beyond The Ordinary
Reflection is the redirection of waves (like light or sound) off a surface or a deep, analytical thought process regarding personal experiences and actions. It involves examining, questioning, and learning from events to improve future understanding and actions. Common contexts include physics (light bouncing) and personal/professional development.
Key Aspects Of Reflection.
🔹️ Physics/Science:
▪️ Reflection occurs when waves,
such as light, hit a surface and bounce back, often producing a reversed image. The law of reflection states that the angle of incidence equals the angle of reflection (i = r).
🔹️ Personal Development & Learning:
▪️ This involves 'thinking about
thinking' (metacognition), studying one's own actions to gain insights, improve skills, and foster self-awareness.
🔹️ Professional Practice:
▪️ It is a key tool in professional
development, allowing for the evaluation of decisions and promoting better, more evidence-based practice.
🔹️ Geometry:
▪️ A reflection is a transformation
that flips a shape over a "line of reflection," where every point on the new image is the same distance from the line as the original, but on the opposite side.
Benefits Of Reflective Practice.
🔹️ Learning from Experience:
▪️ It helps individuals understand
what works, what doesn't, and why, maximising the value of experiences.
🔹️ Improved Decision-Making:
▪️ By analysing past actions,
individuals can make more informed decisions in the future.
🔹️ Enhanced Self-Awareness:
▪️ Regular reflection boosts
understanding of one's own strengths and weaknesses.
Beyond The Ordinary
Rotations and Reflections are rigid geometric transformations (isometries) that change a shape's position or orientation without altering its size or shape. A rotation turns a figure around a fixed point, while a reflection flips a shape over a specified mirror line, producing congruent images.
Rotations.
A rotation is a 'turn' of a shape around a fixed center point.
Key Elements: Requires a center of rotation angle (e.g., 90°, 180°) and direction (clockwise or counterclockwise).
Properties: The shape remains congruent to its pre-image.
Example: A shape turned 90 degrees counterclockwise around the origin (0, 0).
Reflections.
A reflection is a 'flip' of a shape over a designated line, known as the line of reflection or mirror line.
Key Elements: The line of reflection.
Properties: Each point of the original shape is the same distance from the mirror line as its reflected image. The resulting image is a mirror image.
Line: The line of reflection can be any line, often the x-axis or y-axis in coordinate geometry.
