PRACTICAL ASSESSMENT TASK (PAT) CONTENTThis CONTENT must be formally assessed within the PAT only!

THE DESIGN PROCESSThe complete Design Process must be applied to the all the Practical Assessment Tasks (PATs) for all the grades.

The Design Process requires that the learner shows clear evidence of ALL of the following:• Problem identification and the formulation of a design brief with a list of specifications and/or constraints• Conducting research and generating graphical ideas/concepts• Selecting the best solution within the context of the design brief• Presenting the final solution as working and3D drawings• Evaluation of the whole process

COMPUTER-AIDED DRAWINGS/DESIGN (CAD)The PAT for EGD requires that some of the presentation drawings have to be generated by a CAD system. CAD is therefore a mandatory part of EGD. However, It is the responsibility of the school to provide a secure facility for CAD and to procure therequired computer hardware and CAD software, which has to be available for use by all the EGD learners.Although there is no prescribed CAD software programme that should to be used, it is advisable to procure a recognized CADsoftware programme that will benefit the learners once they leave school.A period of grace has been extended to schools that are still in the process of preparing a secure CAD facility and/or procuring the required computer hardware and/or CAD software. The learners of those schools have to in the interim, complete all the required presentation drawings of the PAT as instrument drawings.

Basic CAD requirements for all the grades:• Application and management of the specific CAD software.• To draw the required Presentation Drawings of the PAT.

General Suggested Content for all grades:

• Set up a CAD drawing environment• Activate toolbars• Set up and work with layers• Use tools, properties and settings• Draw orthographic and pictorial drawings• Save and retrieve a drawing• Print/plot• Optional: 3D CAD for the more advanced learners.

ENGINEERING GRAPHICS AND DESIGN 2016 THE ANNUAL TEACHING PLAN (WORK SCHEDULE) FOR GRADES 10 – 12

NOTE: This annual teaching plan is suitable for schools that will be teaching CAD either during one period per week/cycle or after normal school hours. It is the responsibility of each school’s EGD teacher(s) to do planning in 2016 TERMs of selecting the resourcematerial, activities and assessment tasks for the annual teaching plan. The hours in the duration column are an indication of the minimum time that should be spent on the specific topic. Thenumber of days, indicated in brackets in the same column, is an indication of the maximum number of school days forthe specific topic. All the assessment tasks for each topic have to be completed within the allocated week(s)/days for the topic. In order to successfully implement the annual teaching plan for EGD, the timetable has to be adjusted to allow for fourhours contact time during a five-day week.

NOTE:The sequencing and/or allocated week(s)/days of these annual teaching plans may be altered. However the altered sequencingand/or allocated week(s)/days have to be approved by an Engineering Graphics and Design Subject Advisor or Co-ordinatorbefore the end of 2015 and all the topics and prescribed content have to be contained.

6.4 Examinations

The Engineering Graphics & Design examination papers should, in terms of format and content, be of a similar or higher standard than the DBE’s examination/exemplar papers. The mark allocations should also be similar to the DBE’s examination/exemplar papers.In order to ensure the validity of examination papers, all papers should consist of original questions. Complete previous EGD exam papers, whether internally or externally set, may therefore not be used again. However, individual questions from a previous question paper may, preferably with some changes, be used again.

Format and composition of the final EGD examination papers are as follows
