  2. 2. TECH3008 Introduction to Educational Technology Presentation Two: Visual Principles
  3. 3. Part One Types of Instructional Images
  4. 4. A simple representation of forms or objects by means of lines, curves and indicators to explain idea or show relationship. Line Drawing
  5. 5. A simple and attractive artwork that helps simplify concept or make an idea or relationship simple and clear. Illustrated Drawing
  6. 6. A simple drawing uses symbols, directions, keys and icons t o simplify an actual location or situation. Kroki
  7. 7. A group of pictures in a specified sequence that tell a story or illustrate a phenomena with titles and captions. Sequenced Drawing
  8. 8. A complex picture aims to explain the similarities and differences between two or more objects. Comparative Drawing
  9. 9. A simple comic drawing designed to tell a story and evoke emotions and consists of one or more frames with captions. Cartoon

  23. 23. Part Two Visual Literacy
  24. 24. Visual Literacy (VL) <ul><li>1. Defining Visual Literacy </li></ul><ul><li>“ Visual Literacy means being able to read and compose images”. </li></ul><ul><li>“ The ability to discriminate and interpret visual actions, objects and other images, while gaining meaning from them ”. </li></ul>
  25. 25. Visual Literacy (VL <ul><li>1. Defining Visual Literacy </li></ul><ul><li>“ Visual literacy skills are required for effective learning and teaching via images”. </li></ul>
  26. 26. Visual Literacy (VL) <ul><li>2. The importance of Visual Literacy </li></ul><ul><li>VL uses images to teach critical and creative thinking, communication and visual literacy. </li></ul><ul><li>VL increases student competence in constructing meaning from images that incorporate various curriculum-based subjects. </li></ul><ul><li>VL helps students sharpen their powers of observation. </li></ul>
  27. 27. Visual Literacy (VL) <ul><li>2. The importance of Visual Literacy </li></ul><ul><li>VL increases ability to locate information, analyze, reason and form conclusions about the photograph. </li></ul><ul><li>VL opens up new worlds for students and engages them to write in more meaningful ways. </li></ul><ul><li>VL helps students to think more consciously about the details they see. </li></ul>
  28. 28. Visual Literacy (VL) <ul><li>3. Enhancing student’s visual literacy: How? </li></ul><ul><li>By asking your students the right questions, they can learn to read photographs and discovering the story behind the image. </li></ul>
  29. 29. Visual Literacy (VL) <ul><li>3. Enhancing student’s visual literacy: How? </li></ul><ul><li>For Example: </li></ul><ul><li>What information is conveyed by: </li></ul><ul><ul><li>gesture? </li></ul></ul><ul><ul><li>expression? </li></ul></ul><ul><ul><li>the clothing worn in the photograph? </li></ul></ul><ul><ul><li>the background? </li></ul></ul><ul><ul><li>the use of props? </li></ul></ul>
  30. 30. Visual Literacy (VL) <ul><li>3. Enhancing student’s visual literacy: How? </li></ul><ul><li>For Example: </li></ul><ul><li>- Who created the image? </li></ul><ul><li>- Who is the audience of the image? </li></ul><ul><li>- For what purpose was the image created? </li></ul><ul><li>- What is the message of the image? </li></ul><ul><li>- Why was the image arranged that way? </li></ul>
  31. 31. Visual Literacy (VL) <ul><li>4. Student objectives/roles </li></ul><ul><li>Practice the skills of observing and interpreting photographs. </li></ul><ul><li>Transform visual information into strong descriptive language. </li></ul><ul><li>Find/create images that describe/illustrate a specific point of view or issue. </li></ul>
  32. 32. Part Three Visual Elements Syntax and Semantics
  33. 33. Visual Elements: Syntax and Semantics <ul><li>The Language of Visual Literacy </li></ul><ul><li>Visuals are a language that allow us to produce and communicate thoughts and images about reality. </li></ul><ul><li>The symbols used in visual communication are not a fixed vocabulary (dictionary) . </li></ul>
  34. 34. Visual Elements: Syntax and Semantics <ul><li>The Language of Visual Literacy </li></ul><ul><li>Visual communication is made up of symbols whose meaning results from their context . </li></ul><ul><li>A visual meaning is formed by seeing and thinking . </li></ul>
  35. 35. Visual Elements: Syntax and Semantics <ul><li>Visual Semantics </li></ul><ul><li>Semantic is the study of language meaning . </li></ul><ul><li>Visual semantics are the structural, cultural, communicative and social signs relate to meaning. </li></ul><ul><li>Examples of visual semantics signs includes: purpose, photo creator, date & time of shooting, purpose, context, audience, relationships… </li></ul>
  36. 36. Visual Elements: Syntax and Semantics <ul><li>Visual Syntax </li></ul><ul><li>Syntax is the grammatical arrangement of words in sentences . </li></ul><ul><li>VL syntax is the form of building of blocks of an image. These blocks are called visual elements . </li></ul><ul><li>Examples of visual elements includes: scale, dimension, arrangements, framing, motion, colour, light, shadow, juxtaposition, relative size, foreground, background… </li></ul>
