Goals for Class

1
Goals for Class

• To learn about the interactive teaching model
  called presentation.
• To learn about components of a lesson establish
  set, advance organizer, and closure

2
Rationale for UsingPresentation (Figure 7.1)
3
Considerations

• 1/6 to 1/4 of all classroom time is devoted to
  presentation.
• Use of presentation increases with grade
  levels-from elementary to high school.
• Its a popular model among teachers.
• Reflect
• Youve experienced 2300 hours of lecture during
  13 years of K-12 instruction.
• How do teachers make a presentation (lecture)
  effective?

4
Planning for Presentation

• Prepare learning outcomes.
• Choose content.
• Conceptual mapping
• Pre-assessing students prior knowledge
• Select advance organizer.
• Adapt presentation for differing student
  abilities.
• Use photographs, diagrams, illustrations.
• Use varying cues and examples.
• Be concrete.
• Plan for materials, time and space.

5

• Prepare Learning Outcomes
• The students will be able to classify a squid as
  cephalopod by explaining how they are similar and
  different from other cephalopods.

6
Instructional Sequence

• Review, clarify aims and establish set.
• Present advance organizer.
• Present learning materials.
• Monitor and check for understanding and
  strengthen student thinking.

7
Time
TEACHER ACTION TIME
Review, clarify aims and establish set. 2 min.
Present advance organizer. 3 min.
Present learning materials. 20 min.
Monitor and check for understanding and strengthen student thinking. 10 min
8
Space

• Arrange furniture and area for presentation.
• Establish board space for posting visual aids.
• Group students in pairs for Turn and Talk.

9
Arrangement of Furniture (Figure 7.7)
Traditional Row and Column

• Helps focus students attention on teacher and
  presentation area
• Supports individual learning

10
Arrangement of Furniture
U-Shaped or Horseshoe - Paired Seating

• Helps focus students attention on teacher and
  presentation area
• Supports cooperative learning (Turn and Talk)

11
Aspects of Clear Presentations (Figure 7.10)

• Be clear about aims and points.
• Go through your presentation step by step.
• Be specific and provide several examples.
• Check for student understanding

12
Materials

• Visual Aids
• Handout for Note-Taking

today.2 things you would like to know more
about cephalopods.1 thing about what or how

27
Closure

• Teachers closing statements and questions.
• Causes students to summarize the new knowledge.
• Purpose
• Focuses attention to the end of the lesson
• Organizes students learning
• Scaffolds - bridges knowledge learned during the
  lesson to prior knowledge
• Reinforces knowledge that was learned

28
What is a cephalopod? - This is how my thinking
has changed about squid and other cephalopods.-
What would you like to know more about?
Example

What a
Teacher Says Today, you learned about a group of
animals that are invertebrates and classified as
cephalopods. Now, Turn and Talk. What is a
cephalopod? How has your knowledge changed? What
would you like to know more about?
29
Advance Organizer(see Arends p. 267-270)

• Teachers introductory statements and questions.
• Different from establish set and review
• Purpose
• focuses attention on topic at hand and informs
  students where the lesson is going
• Scaffolds Bridges prior knowledge to knowledge
  to be learned
• Provides structure for knowledge to be learned

What a Teacher Would Say In a few minutes, I
will present information about Cephalopods.
Scientists classify squids as an animal and an
invertebrate. Squids are a type of of
invertebrate called a Cephalopods. You will learn
about the topics in the above conceptual mapping.
I want you to take notes as I speak.
31
Establish Set(see Arends p. 267)

• Teachers introductory statements to get students
  ready for and engage in learning
• Different from other ways of introducing a lesson
  (review, advance organizers)
• Purpose
• Scaffolds gets students to use prior knowledge
  and skills from long-term memory
• Communicates a link to the knowledge to be
  presented.
• Stimulates interests and involvement
• Teacher uses cues such as questions or visual
  images.

The 90s fad included Inky Beanie Baby is a
Cephalopod.
Example
What a Teacher Would
Say During our two classes, we learned about the
parts of a squid. Today you will learn that
scientists classify a squid as a cephalopod. Did
you recognize this Beanie Baby? Inky is a
cephalopod. Is Inky a squid or an octopus? How
would you know?
