|Machining of Material/Metal - Course: Manual working of metal. Methodical course-guide for instructors (Institut für Berufliche Entwicklung, 62 p.)|
In order to ensure that the instructions, demonstrations and exercises go off smoothly, the training must be well prepared. The following is to be made available:
Classroom and workshop
Though the instructions could be given in the workshop, it is better to do it in a room where the trainees have adequate facilities to sit and write.
If a daylight projector shall be used, a bright projection area and electric supply are required.
The demonstrations of the working techniques, followed by exercises, are to be done in the workshop directly on the relevant machine. One machine with the necessary cutting and operating tools, measuring and testing tools and accessories should be available for each trainee. The necessary working tools, related to the Instruction Examples for Practical Vocational Training, are summarized in the Methodical Guide for Instructors.
Sufficient copies of the Trainees' Handbook of Lessons equalling the number of trainees are to be made available. The Trainees' Handbook of Lessons is mainly used in the introductory instruction for introduction and recapitulation. It explains the technical knowledge of one training unit, which is absolutely necessary for mastering the relevant technique, in a clearly arranged and easily conceivable way. Many illustrations add up to better understanding. Tasks and questions are included to recapitulate, strengthen and test the knowledge acquired. But they may also be used by the trainees for acquiring the knowledge by themselves. A summary of all questions is contained in a complex of questions and answers in the present methodical guide in the sub-section of the relevant training unit. Tasks and questions included in the Trainees' Handbook of Lessons are marked with A.
Sufficient copies of the Instruction Examples for Practical Vocational Training, depending on the number of trainees, are to be made available. They explain the technology for practising the examples, supplemented by working drawings. By means of the Instruction Examples ... workpieces can be produced and working algorithms practised to develop essential practical skills. Based on the Instruction Examples ..., the availability of the materials and necessary working tools can be checked and arranged by the trainees themselves.
The Instruction Examples ... of each training unit are arranged with increasing level of difficulty and should be followed in the sequence given.
- Basic Vocational Knowledge - Working of Metal
- Formulas and Tables - Metal
- Machine Elements and Assemblies and their Installation
can be used by the instructor for the instructions to consolidate knowledge and refresh basic knowledge.
The textbook Formulas and Tables - metal is particularly recommended for exercises of technical calculations.
All tools and accessories required for the working technique are to be made available as visual and/or demonstration aids. Various workpieces related to the conditions of the relevant factory are also to be made available for demonstration.
Blackboard drawings are to be prepared prior to the instructions.
If further teaching aids are available, the instructor can complete the Methodical Guide for Instructor.
This will give him a comprehensive survey and facilitate the preparations for the instructions.
Working tools and materials
The trainees' working places are to be checked for neatness, serviceability and completeness of the working tools and materials.
The completeness of the required technological documents (drawings, instruction examples for the relevant working technique) is to be ensured. Tests and/or recapitulations are to be prepared. The materials required for the exercises are specified in the relevant Instruction Examples for Practical Vocational Training - including the required dimensions. In a few cases the raw materials are to be made available in a certain stage of prefabrication that is to be prepared on advance.
