GIZ Skills Development for a Green Economy (SD4GE) II is closely cooperating with the Department of Higher Education and Training (DHET) to bring the latest methodologies in occupational teaching & learning to in-service TVET lecturers. In this context, a number of modular capacity building measures will be rolled out, of which this training forms one.
During this course, you will take a learning journey through real life industry projects from the South African Plumbing and Electrical trade context.
With the help of external local and international experts, you will gain invaluable experience and solve actual local problems in the electrical and plumbing field. You will learn to collaborate with other trades (as no tradesman works in isolation), and to apply and to draw from each other’s strengths and knowledge base.
Throughout the learning journey of 11 weeks in total (5 Modules) you will switch between the role of a facilitator and learner, and experience the situated/project-based learning approach from both sides.
Welcome to the Expert Network. In short, this platform is meant to support all our Project-based Teaching and Learning Alumni after completion of the training event.
The aim of this platform is to serve as a type of transfer and networking platform, where you can freely communicate with each other to brainstorm ideas, share resources, and most importantly: Collaborate on developing ways to integrate the project-based teaching and learning methodology into your teaching. After all, the training has only had an impact if you can apply it in your daily practice.
Feel free to use this space to your benefit by adding content, setting up meetings, and creating discussions in the forum space. We hope that you can harness the full potential of this space to contribute to the constant improvement of education and training in South Africa.This initiative has been implemented by:
We are delighted that you are part of shaping a new sequence of instruction and learning experiences for the educational process in Namibia and the rest of Africa.
Digital tools such as mobile phones, computers, eBooks and more, allow for easy facts-finding. Our current models of teaching that are based on information retention should therefore be reviewed in favor of immersive or applied learning, where doing and the application of facts becomes the center of information and knowledge creation.
This introductory programme was accordingly created to explore how we move the education sector for the artisan industry, from being informed of facts, to participating in facts.
Participants in this programme will be active in knowledge creation, using virtual reality praxis for the plumbing and electrical trades.
We are certain that you will enjoy your knowledge journey with us and your fellow course participants.
Get in touch with what's happening in the industry and resolve real-life trade scenarios, while experiencing a new teaching approach. You will learn through the real-life industry from the South African Plumbing, Electrical, and Welding trade context. This course will give you cross-trade, peer-to-peer development& individual support by working with multi-disciplinary teams comprising NCV, NATED & CoS lecturers, ensuring a smooth transition from competency-based to integrated (occupational qualifications) training
The learner should understand what Backflow is and how it occurs.
What is a Backflow and How must we protect against it?
The movement of any substance in any direction is called flow. So why the term backflow when water moves from an installation towards the municipal potable supply? Firstly, it is assumed that the water in any installation originates from the municipal supply and so the water that flows back towards there is viewed as flowing back and thus called "Backflow".
What has happened to the water that makes it unsafe to return it from where it comes? Firstly, we need to take cognizance of the fact that once the water passes past the water meter it now becomes the homeowner's responsibility and the municipality no longer has control over what happens to it. Once they have lost control over what happens to the water, they do not want to let it back into the municipal system.
We could let the water back into the municipal system if it was tested and certified as SANS 241 quality compliant, but we know that is not practical.
How does Backflow occur?
Simply put, the backflow of water in a plumbing system will occur in a number of instances:
- During maintenance of a system and a siphon is created in part of the system causing a reverse flow.
- When the pressure downstream of the source of supply is increased causing water to flow in the opposite and unintended direction.
- When pressure is lost at the source of supply or pipe bursts simply causes the system to drain to the low-pressure area.
- During Firer Fighting when there is a large draw-off on a communication or service pipe (rare).
