Why use a TSD?

The TSD will be a long term project to address the lack of continuity between class rooms and schools.

Tactual form of Compic, Boardmaker, Writing with Symbols.

May allow MI students to organise and make sense of their environment.

May allow MI students to communicate choices over time.

May allow MI students to express their needs over time.

TSD will be predictable, consistent and allow for anticipation and practise.

Tactual Learning Involves:

Locating objects

Exploring objects

Manipulating objects

Recognising objects

Comparing objects

Organising objects

Using objects for communication.

slide5

Why are Tactual Skills Important?

  • There are two tactual systems:
  • The Discrimination System
  • The Protective System

Tactual skills are important in the development of body awareness.

May allow students to use their hands to obtain information.

May allow students to identify symbols from the TSD.

Kershmann’s Tactual Key Learning Sequence

1. Large, solid geometric figures.

2 Flat figures, smaller than larger, solid geometric figures.

3. Embossed-dot geometric figures, smaller than large,flat figures.

4. Embossed-dot lined figures.

5. Braille cells.

slide7

Three Stages of Tactual Information Processing

1. Sensory Register

2. Short-term memory

3. Long-term memory

slide8

Tactile Defensive Students

There is a difference between being tactile selective and being tactile defensive.

TD students are hypersensitive in the area responsible for providing protective information.

TD students avoid touching as their system misinterprets stimuli as aversive and abrasive.

slide9

TD students may resist touching stimulus if:

Initial presentation startles them.

They have not received sufficient information from the stimulus.

They dislike the texture.

The item is placed directly into the palm rather than against the fingertips.

They are not interested in the item.

The item is messy.

The item is too warm or too cold.

They cannot anticipate the end of the experience.

slide10

TSD Cards

Made from corrugated plastic, cut to shape.

Marked according to their category, eg food.

Designed to be durable.

Designed to use inexpensive materials where possible.

Designed to be produced easily.

Use a standard font and size ie. Comic Sans, Bold, N36.

Cards stored in categories so they can be easily found/returned.

Changes will need to be made over time as refinements are made. This is a work in progress!
