Teaching Media Chapter 5 - VISUAL PRINCIPLES

VISUAL PRINCIPLES

THE ROLE OF VISUALS IN INSTRUCTION
- One role that visuals definitely play is to provide a concrete referent  for ideas.
- Visuals can simplify information  that  is difficult to understand.
- visuals provide a redundant  channel; that is, when accompanying spoken or written verbal information they present that information in a different modality,  giving  some  learners  a  chance  to  comprehend visually what they might miss verbally.

VISUAL LITERACY
Consider the sorts of visuals that are used every day for important  communication purposes, such as the emergency information  cards in airplanes or highway signs that  warn  of dangerous  curves or  obstructions.

Visual literacy can be developed through two major approaches
- Input  strategies. Helping learners to decode, or "read," visuals proficiently by practicing visual analysis skills (e.g., through  picture analysis and discussion of multimedia and video programs).
- Output strategies. Helping learners to encode, or "write," visuals-to express themselves and communicate with others (e.g., through planning and producing photo and video presentations).

Decoding: Interpreting Visuals
- Developmental  Effects, many variables affect how a learner decodes a visual. Prior to the age of 12, children  tend  to  interpret  visuals section  by section rather than as a whole.
- Cultural Effects, the act of decoding visuals may be affected by the viewer's cultural background. Different cultural groups may perceive visual materials in different ways.
- Visual Preferences, in selecting visuals, teachers have to make appropriate choices between the sorts of visuals that are preferred and those that are most effective.

Encoding: Creating Visuals
Another route to visual literacy is through  student  creation  of visual presentations.  Just as writing  can spur reading, producing media can be a highly effective way of understanding  media.

VISUAL LITERACY EDUCATION
“Visual Education“, the district's curriculum guide, encourages teachers to consider visual  learning styles and emphasizes the importance of visuals in developing creativity and critical thinking skills

GOALS OF VISUAL DESIGN
Good visual design tries to achieve at least four basic goals in terms of improving communication:
- Ensure legibility.
- Reduce the effort required to interpret the message.
- Increase the viewer's active engagement with the message.
- Focus attention  on the most important parts of the message.

PROCESSES OF VISUAL DESIGN
Teachers, designers, and others who create visual and verbal/visual  displays face a series of design decisions about  how  to  arrange  the  elements  to  achieve their goals.  We will group these decisions into three sets:
- Elements: Selecting and assembling the verbal/visual elements to incorporate into the display
- Pattern: Choosing an underlying pattern for the elements ofthe  display
- Arrangement: Arranging the individual elements within the underlying pattern

Elements
- Visual Elements can be subdivided into three categories: realistic, analogic, and organizational (Houghton & Willows, 1987).Including: Realistic visuals, Analogic visuals and Organizational  visuals.
- Verbal   Elements.   Most   displays  incorporate some type of verbal information in addition to visuals such as: letter style, Number of lettering style, Capitals, Color of lettering, Size of lettering, Spacing between letters, and Spacing between lines.
- Elements   That Add  Appeal Let's look at three devices for making displays more  appealing: surprise, texture, and interaction

Pattern
The major factors that affect the overall look are
- alignment
- shape
- balance
- style
- color scheme
- color appeal

Arrangement
- Proximity
- Directionals
- Figure-Ground  Contras
- Consistency

VISUAL PLANNING TOOLS
This chapter emphasizes the design decisions that you must make, not the technical steps involved in the pro- duction processes. These skills grow with practice, and with practice you will find yourself thinking  visually more  often  as you  grapple with in- structional problems.
- Storyboard
- Types of Letters
- Drawing, Sketching, and Cartooning

DIGITAL IMAGES
Digital imaging allows users to capture, edit; display, share, and network still and video images. The technology makes the process very easy for both teachers and students.
- Digital Cameras
- Scanners
- Photo CDs
- Caution When Editing Images

Teaching Media-Chapter 3, The Assure Model

THE ASSURE MODEL Assure model is a procedural guide for planning and conducting instruction that incorporates media and technology. All effective instruction require careful planning Gagne (1985), his research revealed that well-designed lessons start with the student interest The ASSURE model focuses on planning surrounding the actual classroom use of media and technology ASSURE model meant for the individual instruction to use when planning classroom use of media and technology 1. ANALYZE LEARNERS If instructional media and technology are to be used effectively, there must be a match between the characteristics of the learner and the content. Several factors, however are critical for making good methods and media decision: a. General characteristics b. Specific country competencies c. Learning styles a. General Characteristics Include broad identifying description, such as age, grade level, job or position, and cultural or socioeconomics factors. ...

TEACHING MEDIA – CHAPTER 1 MEDIA, TECHNOLOGY, AND LEARNING LEARNING Learning is the development of new knowledge, skills, or attitude as an individual interacts with information and the environment. Thus, the learning process involves the selection, arrangement, and delivery of information in an appropriate environment and the way learners interact with that information. Psychological Perspectives on Learning Behaviorist Perspective . In the mind 1950s, the focus of learning research started to shift from stimulus design (communication) to learner response to stimuli. Cognitivist Perspective. Behaviorists refuse to speculate on what goes on internally when learning takes place. The three key concepts of mental development in Piaget’s work are schemata, assimilation, and accommodation (Piaget, 1977). Schemata . Schemata (singular, schema) are the mental structures by which individuals organize their perceived environment. Assimilation . Assimilation is the c...

Teaching Media Chapter 4 - MEDIA AND MATERIALS

MEDIA AND MATERIALS MANIPULATIVES Real objects-such as coins, tools, artifacts, plants, and animals-are some of the most accessible, intriguing, and involving materials in educational use. They are known as manipulative because students may handle and inspect them.  Example: The collection of Colonial era coins, frogs dissected in the college biology, laboratory, the real baby being bathed  in the parenting class-these are just a few examples of the potential of real objects to elucidate the obscure and to stimulate the imagination. Verbalism Verbalism is a term that refers to parroting words without meaningful  understanding.  To build schemata that have meaning and relevance in their lives, learners need a base in concrete experience, and bringing real objects into the classroom can help in this. Cutaways : Devices such as machines with one side cut away to allow close observation of the inner workings Specimens : Actual plants, anima...
