4 INTRODUCTION A. What is Plumbing about? Plumbing is the skilled trade of working with pipes, tubing and plumbing fixtures for water systems and the drainage of waste. Plumbing also refers to a system of pipes and fixtures installed in a building for the distribution of drinking water and the removal of waterborne wastes. In Plumbing, students acquire the skills to install sanitary fittings, water piping to buildings and sewerage systems. B. Why is Plumbing important in the Construction learning programme? The plumbing industry is a basic and substantial part of every developed economy due to the need for clean water, and proper collection and transport of wastes. Most building structures require plumbing. Students interested in careers in the construction industry must be well informed of plumbing principles and requirements. C. The link between Plumbing and the Critical and Developmental Outcomes In Plumbing, students develop the skill to work in teams and to identify and solve problems. Students also learn to understand and contribute to the environment by meaningfully interpreting information which they come across. Students have the opportunity to develop an understanding of the world as a set of related systems by recognising the impact that the different environments can have on the construction industry. Students explore educational and career opportunities in the industry and in important building services D. Factors that contribute to achieving Plumbing Thorough preparation for teaching and learning activities An environment conducive to teaching and learning through effective learner support, motivation, commitment and a positive attitude An interest in plumbing Exposure to construction environments. 2 Department of Education

5 1 DURATION AND TUITION TIME This is a one-year instructional programme comprising 200 teaching and learning hours. The subject may be offered on a part-time basis provided the student meets all the assessment requirements. Students with special education needs (LSEN) must be catered for in a way that eliminates barriers to learning. 2 SUBJECT LEVEL FOCUS Explain equipment, tools and machinery used in Plumbing. Identify and use machines, tools, methods and processes to produce different Plumbing products. Explain and apply relevant health and safety procedures and practices. 3 ASSESSMENT REQUIREMENTS 3.1 Internal assessment (50 percent) Theoretical component The theoretical component forms 40 percent of the internal assessment mark. Internal assessment of the theoretical component in Plumbing Level 2 takes the form of observation, class questions, group work, informal group competitions with rewards, individual discussions with students, class, topic and semester tests and internal examinations. Lecturers can observe students when marking exercises from the previous day and asking class questions. Assignments, case studies and tests can be completed at the end of a topic. Tests and internal examinations must form part of the internal assessment Practical component The practical component forms 60 percent of the internal assessment mark. Practical components include applications and exercises. All practical components must be indicated in a Portfolio of Evidence (PoE). Internal assessment of the practical component in Plumbing Level 2 takes the form of assignments, practical exercises, case studies and practical examinations in a simulated business environment. Students may complete practical exercises daily. Assignments and case studies can be completed at the end of a topic. Practical examinations can form part of internal practical assessment. Some examples of practical assessments include, but are not limited to: A. Presentations (lectures, demonstrations, group discussions and activities, practical work, observation, role-play, independent activity, synthesis and evaluation) B. Exhibitions by students C. Visits undertaken by students based on a structured assignment task D. Research E. Task performance in a Structured Environment Department of Education 3

6 Definition of the term Structured Environment For the purposes of assessment, Structured Environment refers to a simulated workplace or workshop environment. Activities in the simulated workplace or environment must be documented in a logbook with a clear listing of the competencies to be assessed. The following information must be contained in the logbook: Nature of department or environment in which practical component was achieved Activities in the environment with which to achieve the Time spent on activities Signature of facilitator or supervisor and student For the logbook to be regarded as valid evidence, it must be signed by an officially assigned supervisor. Evidence in practical assessments All evidence pertaining to evaluation of practical work must be reflected in the student s PoE. Assessment instruments used for the purpose of conducting these assessments must be part of the evidence contained in the PoE Processing of internal assessment mark for the year A year mark out of 100 is calculated by adding the marks of the theoretical component and the practical component of the internal continuous assessment (ICASS) Moderation of internal assessment mark Internal assessment is subjected to internal and external moderation procedures as set out in the National Examinations Policy for FET College Programmes. 3.2 External assessment (50 percent) A national examination is conducted annually in October or November by means of a paper(s) set and moderated externally. A practical component will also be assessed. External assessment details and procedures are set out in the Assessment Guidelines: Plumbing Level 2 4 WEIGHTED VALUES OF TOPICS TOPICS WEIGHTED VALUE 1. Introduction to Plumbing 15% 2. Plumbing principles and Code of Practice 15% 3. Materials, tools and equipment used in the plumbing industry 10% 4. Pipe assembly for water reticulation 25% 5. Cutting and joining of metals 10% 6. Set out below-ground drainage systems 25% TOTAL CALCULATION OF FINAL MARK Internal assessment mark: Student s mark/100 x 50 = a mark out of 50 (a) Examination mark: Student s mark/100 x 50 = a mark out of 50 (b) Final mark: (a) + (b) = a mark out of 100 All marks are systematically processed and accurately recorded to be available as hard copy evidence for, amongst others, reporting, moderation and verification purposes. 6 PASS REQUIREMENTS A student must obtain at least 50 percent in ICASS and 50 percent in the examination to achieve a pass in this subject. 4 Department of Education
