    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems and make decisions using critical and creative thinking:
  • Note: The ability of the learner to identify anomalous data and to determine the relationship between structural features and stratigraphic units will indicate that the learner is proficient in problem solving and in the use of creative thinking processes. The cognitive ability of the learner to construct and interpret a geological cross section, contributes to his/her problem solving ability and will indicate the learner's problem solving capabilities by using critical and creative thinking to make decisions. 

  • UNIT STANDARD CCFO WORKING 
    Work effectively with others as members of a team, group, organisation or community:
  • Note: The ability of the learner to accept and interpret work instructions and report anomalous conditions identified during the course of the assignment indicates that he/she can work effectively as a team member in the bigger organisational environment. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively:
  • Note: The selecting of the appropriate data types from the specific data set will indicate that the learner can manage and organise activities responsibly and effectively. 

  • UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information:
  • Note: The correct formatting and plotting of data and the interpretation of the cross section will indicate that the learner can collect, analyse, organise and evaluate information. The identification of anomalous data that can affect the reliability of the final product will enhance the learner's ability to critically evaluate geological data. 

  • UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written presentations:
  • Note: The construction and interpretation of the cross section and the recording and reporting of the results in the correct format will indicate the learner's efficiency in mathematical reasoning and written/oral presentations. 

  • UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically, showing responsibility towards the environment and health of others:
  • Note: The effective interpretation of stratigraphic and structural relationships from geological cross sections in accordance with accepted geological procedures would indicate that the learner is proficient in the appropriate use of science and technology. 

  • UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation:
  • Note: The ability of the learner to identify anomalous data and to deal with this by applying problem solving techniques will indicate his/her proficiency in understanding that a specific action or decisions taken have more than one effect. Identification of the relationship between structural features and stratigraphic units will assist in the learners understanding interrelationship of individual systems.

    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.
