    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 a representative logging and sampling section avoiding bias and the effective taking of samples according to the correct procedure, indicates that the learner can make decisions, using critical and creative thinking processes. 

  • 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 collection of the sample material, 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 identify, log and sample a face will indicate his/her effective relationship with the group. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively:
  • The correct logging and effective sampling of the face within the required time and legal constraints will indicate that the learner can organise and manage activities in his/her work environment. 

  • UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information:
  • The ability of the learner to correctly identify the stratigraphic sequence, above, within and below the selected mining horizon, and the correct recording of the required geological parameters according to accepted geological principles, will enhance his/her proficiency to collect, analyse, organise and critically evaluate information. The correct identification of anomalous geological features that can affect the reliability of the logging and sampling results and their complete recording in the required format will enhance the learner's ability to critically evaluate exposed geological features. The correlation and evaluation of the newly acquired and processed geological interpretation with adjacent sections and/or borehole data indicates that the learner can critically evaluate information. 

  • 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 lithological characteristics and the compilation of a complete logging and sampling 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 hazardous, substandard or anomalous 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 use of scientific geological nomenclature and technical knowledge will 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 recognizing that problem-solving contexts do not exist in isolation:
  • The ability of the learner to interpret the geology of the selected mining horizon and roof/floor lithologies between mining sections will indicate his/her proficiency in understanding that a specific workplace cannot be logged and sampled in isolation. Utilizing 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 solve actual and potential problems that can affect the reliability of the logging and sampling results, to communicate effectively and to organise his/her work, contributes to the development of the learner. The correct identification and taking of sampling intervals will indicate 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.
