SECTION A: (Educator Information)  

INTRODUCTION/BACKGROUND  
The 16 Curriculum and Assessment Policy Statements subjects which contain a practical component  all include a Practical Assessment Task (PAT), i.e. a Practical or Performance Assessment Task.  These subjects are:  

  • AGRICULTURE: Agricultural Management Practices, Agricultural Technology 
  • ARTS: Dance Studies, Design, Dramatic Arts, Music, Visual Arts 
  • SCIENCES: Computer Applications Technology, Information Technology 
  • SERVICES: Consumer Studies, Hospitality Studies, Tourism 
  • TECHNOLOGY: Civil Technology, Electrical Technology, MECHANICAL TECHNOLOGY and  Engineering Graphics and Design.  

A PAT allows the educator to directly and systematically observe applied competence. The PAT  comprises the application/performance of the knowledge, skills and values to that subject and counts  25% (i.e. 100 marks) of the total promotion/certification mark out of 400 for the subject.  
The PAT is implemented across the first three terms of the school year, which is broken down into  different practical skills that make up the PAT.  
Any profession requires of its members a thorough grounding in both theory and practice, and  MECHANICAL TECHNOLOGY is no exception. It is emphasized that the goal of the Practical  Assessment Task is to produce a skilled learner in each specialisation field. A nation's true wealth is  in its manpower and education should aim to develop the talents of the learner so that he/she can  contribute to the well-being of society by using scientific and technological resources with the greatest  efficiency and by continuing to develop them.  
To prepare a learner to develop skills in MECHANICAL TECHNOLOGY, in each specialisation field:  

  • An attitude where the learner can selectively assimilate ideas, gather evidence and facts, and  drawing logical conclusions and put them to good use creatively and with imagination; 
  • A capability to express ideas and information clearly by speech, writing, sketching or drawing; 
  • A willingness and capability to accept and exercise responsibility, to make decisions, and to  learn by experience. 

Attributes such as these cannot all be achieved in a classroom. A sound knowledge of engineering  science is essential to equip the MECHANICAL TECHNOLOGY learner with the necessary practical  capabilities for the required processes. Training is the art of acquiring essential skills to bridge  between trade theory and practice.  
Practical application in the workshop must therefore be made an interesting and challenging  experience, mentally and physically, with encouragement to the learner to use his/her initiative,  curiosity and persistence in finding things. The giving of some degree of responsibility during practical  application is very important as a stimulus and to develop self-confidence.  

2. TEACHER GUIDELINES
2.1 Administration of the PAT
Teachers are requested to make copies of the different assessment criteria of the PAT document.  These documents need to be distributed to the learners at the beginning of each phase of PAT to be  completed. The Practical Assessment Task for Grade 10 is internally set and moderated.  
Teachers must attach due dates for the different terms of the PAT task (refer to the CAPS document).  In this manner, learners can easily assess their progress. Instances where formal assessments take  place, it is the responsibility of the teacher to administer assessment.  
The PAT should be completed in the first three terms. The PAT should be based and completed  under controlled conditions (Refer to the Mechanical Technology CAPS Grade 10–12).  
Teachers must ensure that each learner has a portfolio of evidence and that it is kept in a safe place.  
This must be available at all times when requested for by a department official for scrutiny or  moderation.  

2.2 Assessment of PAT
Frequent and developmental feedback is needed to guide and give support to the learner to ensure  that the learner is on the right track.  
Both formal and informal assessment should be conducted in different terms to ensure that the  embedded skills are covered for the PAT. Informal assessment can be conducted only to monitor  progress of the term in which the learners are engaged. Formal assessment should always be  conducted by the teacher and will be recorded. 

2.3 Moderation of PAT
During moderation of the PAT, the term tasks will be presented to the moderator with the assessment  criteria and marks obtained. 
Where required the moderator should be able to call on the learner to explain the function, principles  of operation and also request the learner to demonstrate the skills acquired through the capability  tasks for moderation purposes.  
Upon completion, the moderator will, if necessary, adjust the marks of the group up or downwards  depending on the decision reached as a result of moderation.  

2.4 CONSEQUENCES OF ABSENCE/NON-SUBMISSION OF TASKS
If a learners’ Practical Assessment Task is incomplete or unavailable with valid reason, the learner  will be given three weeks before the commencement of the final end-of-year examination to submit  outstanding task. Should the learner fail to fulfill the outstanding PAT requirement, such a learner will  be awarded a zero for that PAT component.  
A learner's results are regarded as incomplete if he/she does not offer any component of the PAT  task. He/she will be given another opportunity based on the decision of the Head of the assessment  body.  
Should the learner fail to fulfill the outstanding PAT requirement, the marks for these components will  be omitted and the final mark for Mechanical Technology will be adjusted for promotion purposes in  terms of the completed  

2.5 Management Plan:

Phase 1: Complete at the end of first term – April. 
Phase 2: Complete at the end of second term – July. 
Phase 3: Complete during third term - End of September. 
Phase 4: Plan and start task during term one and complete at the end of September (third term).

SUBJECT: Automotive (Mechanical Technology)   EDUCATOR:  
PROJECT:   NUMBER OF LEARNERS IN CLASS:  
Term Two PAT Phase Two  JOINING:  Plates and thread cutting  

Resources Required:

  • Mild steel flat bar of 100mm (length) x 96mm (breadth) x 5mm (thickness).  (if flat plate is used, ensure that two sides are parallel to each other, i.e all angles must be  90⁰). 
  • Appropriate metal hand files. 
  • Vernier and other measuring equipment (callipers, steel rule etc). 
  • Marking medium (Engineers blue, Koki pen, chalk etc.) 
  • Marking off instruments (Square, combination square, scriber etc.) 
  • Appropriate Personal Protection Equipment (PPE). 
  • Centre punches. 
  • Hammers. 
  • Hacksaw. 
  • Appropriate sized Twist Drill bits to enable M10 and M12 threads to be cut. 
  • Press drilling machine. 
    (If a hand drill machine is used, then use a large engineer’s square against the drill  machine or some similar jig, to ensure a perpendicular hole)  

Instructions:
11) Use a marking medium to prepare the two ends of the material for marking (96mm width). 
12) Use a steel rule to check / ensure that the material can be cut / filed / worked down to  100mm in length i.e. if pre-cut pieces are used the starting length should be about 120mm. 
13) Use engineers square on either of the 100mm ends of the material to plan a square line. 
14) Use a scriber to scribe this straight square line about 4mm from the rough edge. 
15) Use the square and scriber on the opposite end of the material to scribe a straight, square  line so that the material between the lines is 100mm in length. (ensure lines are parallel) 
16) Request an informal assessment on the marked lines before proceeding. 
17) By cutting with a hacksaw about 1-2mm on the waste side of the above lines, demonstrate  your hacksaw skill by cutting off the excess material parallel to the scribed lines.  (Do NOT cut on the line).  
18) Request a formal assessment on your ability to cut straight before proceeding (4).  
19) First use a rough-cut bastard file to file both ends, use the engineers square regularly to  check that you are filing the width square (along the 96mm edge) AND for square-ness  across the 5mm thickness.  
20) Request a formal assessment on your ability to file all four sides square and to size,  before proceeding (10).  
21) Then using a smooth double cut file, complete the filing process, so the material is reduced  to 100 x 96mm with square corners and thickness, according to the tolerance table as in  Annexure A.  
22) Request formal assessment on ability to file square to tolerance (7). 
23) Measure from one end 50mm, to establish and scribe a straight square line across the  centre width of the plate.  
24) On this line measure from one 100mm edge, 48mm along the line to establish and mark  the centre of the line above and thus the center of the rectangular plate.  
25) Use the centre punch to mark this point for drilling.  
26) Request informal assessment on your ability to mark and punch this centre point,  before proceeding (5).  
27) Measure and mark a point 20mm from each end on the 100mm length.  28) Scribe a line across the width of the material at the 20mm marks, parallel to the mid line  scribed earlier.  
29) Along one 20mm line, measure and mark from both sides 20mm inwards and centre punch  these TWO marks in preparation for drilling.  
30) Use this punch mark to scribe the two 20mm radii on the two corners 
31) Along the other 20mm line, measure and mark from each side 15mm inwards and centre  punch these TWO marks in preparation for drilling.  
32) Cut off on the waste side of the scribed radii lines.  
33) File down to the line, in two stages, firstly with a bastard file and then a double cut smooth  file to complete the radii to a smooth finish.  
34) Request formal assessment on your ability to mark and punch these centre points  accurately and the filling of the radii, before proceeding (6+5).  
35) Use a press drill machine drilling a hole, center of the plate suitable to cut a M12 thread.  (Ensure the hole is perpendicular, using large engineers square if hand drill is used!) 
36) Request an informal assessment / guidance on attempt and required skill to drill the  other holes perpendicular to the surface, before proceeding.  
37) Use a press drill machine to drill four holes on the center punched holes positioned on the  15 / 20mm cross lines and the 20 / 20mm cross lines on the plate, suitable to cut a M10  thread. (Ensure holes are perpendicular, use large engineers square if hand drill is used!)  
38) Place the drills in the holes, use an engineer’s square up against the drill to testing square. 
39) Hand task in for formal assessment on your ability to drill perpendicular holes (1+4). 
40) Using a thread cutting tap, cut appropriate 1x M12 and 4x M10 thread in these five holes,  square to the surface.  
41) Test for effective square thread by turning-in a long M12 and M10 bolt or threaded rod and  an engineer’s square, up against the rod. 

NOTE - Safety and Finishing (-5) is the last assessment component that may apply:  

  • A maximum of Five NEGATIVE marks allocated.  
  • Less 1 mark for vice (jaw) damage - clamping marks for overtightening or loose slip. 
  • Less 1 mark for lack of overall manufacturing competency in finishing / “look” of completed  task related to surface finish, edges, square-ness, centrality, etc.  
  • Less 1 mark: Repetitive disregard for the use of PPE and safe use of tools and equipment,  while working in the workshop.  
  • Less 1 mark: Another negative mark for continuing to have a disregard for the use of PPE  and safe use of tools and equipment, while working in the workshop.  
  • Less 1 mark: Quality versus Time – “rush” job vs inefficient time to complete a good job.  

42) Hand the task in for formal assessment on your ability to cut square /  perpendicular thread in different sized holes (5).  
43) Clean any burs, roughness and dirt caused by the drilling, cutting and manufacturing  process.  
44) Hand the task in for formal final assessment on your ability to clean your project (3).
