Before starting with the actual Learning Project, please familiarise yourself with the information on this page!

How to use this workbookThe DSPP learning support material provides additional teaching aids for the knowledge and practical skills modules based on the NOCC-A21 syllabus that was developed according to the new QCTO curriculum. The workbooks supplement the existing learning material available at the TVET colleges and consist of work assignments, which can be used by the lecturers as part of the assessments. The completed assessments will be filed in the Portfolio of Evidence (PoE) and form one of the admission requirements for the trade test at the end of the apprenticeship.

The workbooks focus on practical, workplace-driven aspects and contribute to personal growth and development of the apprentice. The focus is the apprentice!

The workbooks are arranged under headings (viz. Introduction to the Learning Project, Preparation, Theory, Work Assignments and Assessments, Further Development and Workplace Experience), using colours and icons to help the apprentice navigate easily through the workbook and are designed to suit the level of the apprentice. The mentioned time allocation is applicable to the knowledge and practical modules done at the TVET college only.

Below is a short description of the different sections of the workbook.

Introduction to the Learning ProjectOn page 4 of the workbook, the apprentice is introduced to the Learning Project. The section begins with a motivational quote, picture or story to inspire the apprentice to 'think out of the box' and to apply this mind-set to work with the workbook. With a short paragraph introducing the upcoming Learning Project, the apprentice will have an idea of how the practicals will be applied in class.

PreparationThe next heading "Preparation" is one of the most important parts of the workbook and can be used at the beginning of the Learning Project. The aim is to arouse the interest of the apprentices in the Learning Project by challenging them with problems and questions varying in difficulty and presented in a fun, creative and mostly scenario-based fashion. There is no pressure on the apprentices to have all the answers - this will encourage them to participate.

TheoryThe theoretical section entails the formal process of instruction as set out by the NOCC-A21. The lecturer is aware as to the desired outcomes and range of topics and he/she plans the process in such a way that training is effective and completed within the allocated time frame.

Work Assignments & AssessmentsWork assignments are completed by apprentices in order to assess their knowledge and skills and to determine effectiveness of the training against the stated outcomes. The assessments and evaluations are done objectively and present an opportunity to identify and schedule remedial activities. These must be formally agreed upon between the apprentice and the lecturer. Furthermore, the assessments serve as proof for the completed knowledge and practical skills modules in the Portfolio of Evidence (PoE).

Further Development & Workplace Experience"Further Development" aims to allow apprentices to delve deeper into the featured topics. The format may include references to websites, books, documents, projects or experiments. Lecturers do not formally keep track of apprentices’ activities in this section. The employment of the apprentices at the workplace is aimed to provide “real-life” work experience. The "Workplace Experience" section of the workbook ensures that apprentices complete a variety of tasks at the workplace.

Figure 1: Self care

My progress in becoming aProfessional Plumber

Do you care enough for yourself? Can you see a correlation to the topic of this Learning Project?

1. Introduction to Learning Project 3It is a fact that any tradesman relies very heavily on his tools. These tools are often very expensive, and tradesmen get attached to the tools that they trust.

The tools that a plumber uses on a daily basis are a combination of hand- and power tools, which require specific ways of being used, cared for and stored.

Not only does proper care have an influence on the life-span of the tools, but safety is also enhanced in properly cared for tools.

Why is it important to dry tools before storage?

ManufacturingPlumbing installations are executed according to client's specifications using different pipes, fastening material, sanitary products and other material. To perform those tasks, different basic work techniques are required:

• Cutting

• Metal forming

• Testing (measuring, gauging)

• Joining

All tasks have to be performed in a safe manner using appropriate personal protective equipment (PPE).

In order to meet the required quality, all work has to be tested after completion. In testing, we differentiate between subjective and objective testing.

What do you understand is the difference between subjective and objective testing?

Can you name three different 'testing tools' for each of the two different testing methods (remember, sometimes the tool can be a human organ/ human body part).

Using your examples of testing tools above, think of an example for each of the testing methods and describe the testing method in detail.

2. PREPARATION

This old pipe from the shower has broken off while you were trying to remove it.

Which tool would you use to remove it without further damaging to the wall and pipe?

"Using a stationary lower jaw and a movable upper jaw known as the hook jaw (because of its shape), these hardened, serrated jaws will generate tremendous gripping force when pressure is applied to the handle. However, the unique function and design of a coil and flat spring (located quietly inside the main housing) also permits the tool to easily and quickly be removed from the pipe without loosening the nut when the job is complete or when the tool needs to be repositioned on the material."

Which tool is discussed above and what can you use it for?

"When using a this tool, a mistake people often make is to leave too much air in the cup. Air is compressible but water does not compress very much. So if the cup is full of air, every time you push down, the air compresses and acts like a shock absorber. This means the clog doesn't receive as much force. If the cup is filled with water, the force you apply to the tool is transferred through the water all the way to the cloged area and the force is much more effective. So, when working, there must be some water in the fixture, and the cup must be tilted to remove the air as it is submerged in the water"

Which tool is discussed here and how is it used in the plumbing environment?

Work Assignment 1

ScenarioYou recently had a break-in at the company you work for. The door at the back of the workshop was broken and material was stolen from the store. The door does not have a burglar bar or other security feature fitted to it. Using some rectangular steel tubing and other material that is lying around in the store, your boss asks you to manufacture and fit a security bar on the inside of the door as an immediate measure (see Figure 1 and the drawings in Annexure A and B) for more information.

Task 1.1

Assess the physical work you may have to do and complete a detailed plan of action. List all the steps you need to follow in the correct order and list all hand and power tools you will need for each of the steps.

Make an estimate of how long each step will take you to finish.

To cut the material to size, you are using, amongst other tools, an angle grinder. Before you start cutting, your boss hands you the safe work procedure for the use of the angle grinder that he had started putting in place a while ago. He however cautions that he has not yet completed the document.

He asks you to add the 6 missing safety signs to the procedure and tick the relevant signs for the use of the angle grinder.

Explain one of your choices of relevant warning signs for the use of an angle grinder to the rest of the class.

1.4

Use the safe work procedure for the grinder as a template and complete a similar procedure for a drilling machine. Work out the following:

• Description of work

• Potential hazards

• Personal protective equipment (PPE) required

• PRE-operational checklist / tasks

• Operational checklist / tasks

• POST-operational checklist / tasks
