Evaluation….. Notes to help in Assessing this stage
Aspect 1: conclusion
The validity of the solution
to the problem should be evaluated and justified. Evidence may be provided via
testing of a designed product and expert appraisal or astute interpretation of
data for an investigation, even if the conclusion appears contradictory to the
accepted theories.
Aspect 2: procedure
The suitability of chosen
strategies at each stage of the investigation or project should be assessed
taking into account available resources, including time. Students should not
only state weaknesses, but also indicate how significant the weaknesses are.
For a design project, procedures will also relate to testing the solution in
relation to the specifications stated at the planning stage and gaining user
research.
Aspect 3:
recommendations
Suggestions for improvements should be based on the
weaknesses and limitations identified in aspect 2. Improvements may be
presented in a variety of forms, such as drawings, a modified design
specification, or a new set of variables. For investigations based on data
collection, modifications should address issues of precision, accuracy and
reproducibility of the results. The modifications proposed should be realistic
and clearly described. It is not sufficient to state that more precise
equipment should be used or more time allocated. Modifications for a designed
prototype should consider changes to the design for scaling up production and
to produce a design family of products.
