---------------------------------
ASSESSMENT
In order to achieve this unit, candidates are required to present sufficient
evidence that they have met all the performance criteria for each outcome within
the range specified. Details of these requirements are given for each outcome.
The assessment instruments used should follow the general guidance offered by
the SQA assessment model and an integrative approach to assessment is
encouraged. (See references at the end of support notes).
Accurate records should be made of the assessment instruments used showing
how evidence is generated for each outcome and giving marking schemes
and/or checklists, etc. Records of candidates' achievements should be kept.
These records will be available for external verification.
SPECIAL NEEDS
In certain cases, modified outcomes and range statements can be proposed for
certification. See references at end of support notes.

SUPPORT NOTES
UNIT NUMBER:

UNIT TITLE:
ORGANIC CHEMISTRY FOR TEXTILES
SUPPORT NOTES: This part of the unit specification is offered as guidance.
None of the sections of the support notes is mandatory.
NOTIONAL DESIGN LENGTH: SQA allocates a notional design length to a unit
on the basis of time estimated for achievement of the stated standards by a
candidate whose starting point is as described in the access statement. The
notional design length for this unit is 40 hours. The use of notional design length
for programme design and timetabling is advisory only.
PURPOSE This module will enable the candidate to gain sufficient knowledge of
organic chemistry so that the candidate can proceed to further study of Higher
National Certificate chemistry modules for textiles. This chemistry module will
also act as a support for other textile modules.
SQA publishes summaries of NC units for easy reference, publicity purposes,
centre handbooks, etc. The summary statement for this unit is as follows:
This module will enable you to gain an understanding of organic chemistry
required for the chemistry of fibres and fibre processing. You will learn how to
recognise different classes of organic compounds along with an understanding
of some of their reactions important in textile chemistry. You will also relate
organic chemistry to the formation and structures of polymers used as synthetic
fibres. You will learn how to relate specific classes of organic compound to the
primary structure of wool protein and to the structure of cellulose which serves as
a basis for the further study of natural fibres in other textile or textile chemistry
modules.
CONTENT/CONTEXT Corresponding to Outcomes 1-4:

structural formulae of various organic compounds containing up to eight
carbon atoms in the main chain to include alkanes, alkenes, arenes
(benzene, naphthalene), alkanols, alkanals, alkanones, alkanoic acids
and derivatives (esters, nitriles, anhydrides, amides) aromatic carboxylic

acetates.
APPROACHES TO GENERATING EVIDENCE
Chemical structures and
reactions should be discussed using visual material such as OHP, molecular
models or videos. Tutorials using worksheets should be used to reinforce main
principles. Laboratory demonstrations can be carried out where possible to
illustrate certain areas related to organic reactions.
The outcomes should be tackled in the order shown.
Each candidate should be assessed at appropriate points throughout the
module.
Where a candidate is unsuccessful in achieving an outcome, provision should be
made for remediation and reassessment.
ASSESSMENT PROCEDURES Centres may use Instruments of Assessment
which are considered to be most appropriate.
Examples of Instruments of Assessment are as follows:
Outcomes 1-4
It is recommended that structured questions should be
used here. An appropriate number of questions should
be set in each outcome in order to assess all
performance criteria ensuring that all of the range
statements and evidence requirements are achieved.
PROGRESSION The candidate could progress on to the appropriate SQA
Higher National Unit in Textiles: Fibre/Polymer Chemistry, Dyestuff Chemistry
(Colour and Constitution), Colour Measurement and Specification.
RECOGNITION Many SQA NC units are recognised for entry/recruitment
purposes. For up-to-date information see the SQA guide 'Recognised and
Recommended Groupings'.
