In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
People credited with this unit standard are able to:
  • Demonstrate an understanding of a GUI environment
  • Compare a GUI environment with a text-based environment
  • Write a computer program using an OOP language in a GUI environment
  • Test a computer program using an OOP language in a GUI environment
    The performance of all elements is to a standard that allows for further learning in this area. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit value of this unit is based on a person having the prior knowledge and skills to:
  • Apply the principles of computer programming
  • Demonstrate an understanding of fundamental mathematics (at least NQF level 3)
  • Apply the fundamental principles of Object Oriented Programming 

  • UNIT STANDARD RANGE 
    N/A 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The writing ensures that the program code implements the program design. 

    ASSESSMENT CRITERION 2 
    The writing ensures that the program code does not duplicate objects from available object libraries. 

    ASSESSMENT CRITERION 3 
    The writing ensures that, in the case where an object is not available for a particular GUI requirement, the programs use the application programming interface (API) for the GUI. 
    ASSESSMENT CRITERION RANGE 
    The concept of using the GUI API rather than low level interrupt calls must be demonstarted
     

    ASSESSMENT CRITERION 4 
    The writing ensures that the development includes objects that exhibit polymorphic behaviour. 
    ASSESSMENT CRITERION RANGE 
    Operators can operate on values of different types (integer; real; character; string).
     

    ASSESSMENT CRITERION 5 
    Writing ensures that the development includes the use of abstract data types. 

    ASSESSMENT CRITERION 6 
    Writing ensures that the development includes objects that exhibit inheritance. 
    ASSESSMENT CRITERION RANGE 
    A class inherits behaviour from a superclass. Avoid duplication of common behaviour.
     

    ASSESSMENT CRITERION 7 
    Writing ensures that the development includes individual objects that are managed within container objects. 
    ASSESSMENT CRITERION RANGE 
    Linking and Embedding (OLE Component; Server-Container Object)
     

    SPECIFIC OUTCOME 4 
    Test a computer program using an OOP language in a GUI environment. 
    OUTCOME RANGE 
    Break points; Watch expressions; Call Stack; Immediate and Locals Windows. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Testing includes the program code that is corrected to eliminate errors identified through testing. 

    ASSESSMENT CRITERION 2 
    Testing includes a test plan that describes tests and expected results for all behaviours of all objects. 

    ASSESSMENT CRITERION 3 
    Testing fulfils the test plan 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    The relevant Education and Training Quality Authority (ETQA) must accredit providers before they can offer programs of education and training assessed against unit standards

    Moderation Process:
    Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    1. Performance of all elements complies with the laws of South Africa, especially with regard to copyright, privacy, health and safety, and consumer rights.
    2. All activities must comply with any policies, procedures and requirements of the organisations involved, the ethical codes of relevant professional bodies and any relevant legislative and/ or regulatory requirements.
    3. Performance of all elements is to be completed within the normal range of time and cost that would be expected in a professional environment (eg. In a commercial or government organisation).
    4. Performance of all elements should be performed with a solid understanding of the use of development tools needed in the areas applicable to the unit standard.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
