Stages of Learning

• Acquisition

• Mastery/Fluency

• Generalization

• Maintenance

4

Errorless Learning

• A procedure that reduces the chance of incorrect responses

• Makes use of prompts and prompt fading to reduce incorrect responses

• Reduces potential of learning incorrect responses

5

Prompts

• Prompts increase the effectiveness of teaching by decreasing the likelihood of incorrect responses.

• Types of Prompts– Physical Prompts– Visual Prompts– Verbal Prompts

6

Physical Prompts

• Physically guiding the student

• Hand-over-hand

• Use the least force needed to ensure correct response

• Never physically force the child’s movement

• Effective for teaching motor skills

7

Visual Prompts

• Visual cues to ensure correct response

• 4 types of visual prompts– Gestural– Picture– Model– Positional

8

Verbal Prompts

• Verbal instructions

• Words or phrases

• Can include sign language

9

Prompt FadingGeneral Guidelines

• Determine how the prompt will be faded before you start fading.

• Must be done in an orderly manner.• Begin fading when correct responding

averages 80% correct.• Delay prompt• 2-3 consecutive incorrect responses return to

the last prompt level that the student was successful

10

Prompt FadingPhysical Prompts

• Reduce the force of grip

• Light touch

• Shadowing or change position of prompt

Selection-Based Imitation

• Used to teach receptive language• Sequence of Implementation

– Linear configuration• Ensure attending

– Field expansion• Strengthen scanning and increase field size

– Linear configuration/different positions• Solidify scanning and prevent positional responding

– Two steps• Increase flexible scanning and increase attention

– Transfer to receptive labeling• “Do this.” is changed the label of the item• Gestural prompt is gradually faded• Response comes under control of verbal label of item

32

Prompt FadingVerbal Prompts

• Shorten the instruction

• Shorten the word– Give beginning sounds

33

Discrete Trial Training

• A structured way of teaching

• Each trial has a clear beginning and ending

• Trials are distinct and succinct

• A trial is one set of instructions

Instruction Response Consequence

34

Discrete Trial TrainingComponents

• Presentation of Materials

• Instructions

• Prompting

• Delivery of Consequences

35

Discrete Trial TrainingPresenting the Materials

• Materials are ready and organized

• Unnecessary items are removed from area

• Materials and reinforcers are accessible to trainer

• Items must be randomized each trial

Discrete Trial Training5 Components of Effective Instructions

• Clear and easily identifiable

• Appropriate for the task

• Consistent for new tasks

• Uninterrupted

• Gain student’s attention

40

Delivering ConsequencesCorrect Responses

• Initially reinforce all correct responses

• Once prompts are faded, use praise only to signal correct prompted responses

41

Delivering ConsequencesIncorrect Responses

• Do not use “No, no” prompt

• Remove materials

• If prompt has been faded, do not prompt after first incorrect response

• Present materials and instruction

• Reinstate last successful prompt after 2 incorrect responses

42

Discrete Trial Training

Practice

43

Precision Teaching

• A fluency based set of methods and practice procedures which adjust curricula for each student to maximize learning

44

Precision TeachingExamples of Success

• Students at Malcom X College made 2 grade level gains in 16 hours of instruction (Johnson & Layng 1994)

• Sacajawea Elementary students gained 20-40 percentage points within 3 yrs. on standard achievement tests (Beck & Clement 1991)

• Morningside Academy offers 2 money back guarantee for program• Students will progress 2 grade levels each year• Time on task will increase from 1-3 min. to 20 or more minutes

(Johnson & Layng 1994)• Have not refunded any monies to date

45

Precision TeachingKey Features

• The learner knows best

• Uses frequency for measurement

• Daily charting on the Standard Celeration Chart

• Focused instruction and practice on directly observable behavior

46

Precision TeachingBenefits

• Frequency of response is the basic unit of measurement

• Free operant responding

• Emphasizes teaching sequentially

• Instructional decisions are data based

• Multiple instructional techniques can be utilized

47

Precision Teaching5 Steps

• Select a Task

• Set an Aim

• Count and Teach

• Develop a Learning Picture

• Decide What to Do

48

Precision TeachingSelect a Task

• Countable– The movement must be observable and measurable

• Counting Period– Consistent– At least 8-10 movements

• Correct/Incorrect Pair– Define correct and incorrect movements– Count both correct and incorrect movements for each counting

period• Learning Channel

– Input and Output– Multiple learning channel sets for each skill

• Hard-To-Do– Goal is to teach a new skill

Precision TeachingSet an Aim

• Strategy 1– Use component skill frequencies

• 1.5 to 2.0 times greater than composite skill• Ex. Writes 120-160 digits/minute

– Aim for multiplication facts = 80/mintue

• Strategy 2– Ratio between teacher and student

Adult Skill Rate = Student Skill RateAdult Tool Rate Student Tool Rate

80 = X = 40/minute 100 50

– Ratio between fluent student and student

Precision TeachingCount and Teach

• Count correct and incorrect movements

• Teach– Materials – Prompting– Consequences for correct and incorrect

movements– Practice

55

Precision TeachingDevelop a Learning Picture

• Daily charting

• Draw expected celeration line (minimum celeration line)

• 3 consecutive days below line change teaching strategy

56

Precision TeachingDecide What to Do

• Slice Back– A smaller movement of the original movement– Error rate is higher than correct rate

• Step Back– A movement that is easier than the original movement– Error rate is higher than correct rate

• Change the Counting Period– When endurance is an issue– Duration should equal real life

• Change the Aim– Set a temporary aim lower than the final aim– Gradually increase the aim as each temporary aim is met

57

Precision TeachingStandard Celeration Chart

• Standard charting conventions

• Multiply/Divide– Advantages of multiply/divide

• 1 response/1000 minutes

• 1000 responses/minute
