    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems and make decisions using critical and creative thinking:
  • The ability of the learner to identify anomalous data values and data types and the correcting of gross errors contributes to his/her problem solving ability. The ability to effectively identify and correct errors during the validation process 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:
  • The ability of the learner to accept and interpret work instructions correctly and to request assistance, when required, with the procedure, indicates that he/she can work effectively as a team member in the bigger organisational structure. The standard of work performance will affect the efficiency of the team or group as a whole and the ability of the learner to correctly process geological data will indicate his/her effective relationship with the group. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively:
  • The effective organisation and sorting of the raw data by data type and within data types and the consequent integration of the data will indicate that the learner can organise and manage activities in his/her work environment. The selecting of the appropriate calculation methods for the specific procedure will indicate that the learner can manage and organise activities responsibly and effectively. 

  • UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information:
  • The ability of the learner to obtain/collect and organise actual raw data and to critically evaluate this data for gross errors will enhance him/her proficiency to collect, analyse, organise and evaluate information. The correcting of errors that were detected during the validation process will indicate that the learner can critically evaluate his/her work output prior to submitting the data to other personnel. 

  • UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written presentations:
  • The correct recording of the geological parameters and associated grade characteristics and the compilation of a report in accordance with accepted scientific principles and nomenclature, will indicate the learner's efficiency in written presentations. The appropriate communication with the relevant personnel with regard to the reporting of anomalous data and/or conditions will indicate his/her proficiency in effective oral communication. 

  • UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically, showing responsibility towards the environment and health of others:
  • The correct application of mathematical formulae to accurately analyse the data will indicate that the learner is proficient in the appropriate use of science and technology. The identification of hazardous and sub-standard conditions that can have an effect on the environment and the health of others indicate his/her responsible behaviour in these circumstances. 

  • 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:
  • The ability of the learner to interpret the geological data and grade control parameters will indicate his/her proficiency in understanding that a specific data type cannot be evaluated in isolation. Utilising the information from other sources can enhance problem solving. 

  • UNIT STANDARD CCFO CONTRIBUTING 
    Reflect on, and explore a variety of strategies to learn more effectively and to contribute to the full development of each learner to enhance the social and economic development of the society at large:
  • The ability of the learner to explore more than one strategy to record geological data, to communicate effectively and to organise his/her work, contributes to the development of the learner. The correct identification of anomalous data indicates that the learner accepts responsibility for the economic implications of his/her actions. This will enhance the learning curve of the individual to contribute to his/her own personal growth, socio-economic development and the community at large.
