THE STRUCTURE OF THE PRACTICAL ASSESSMENT TASK (PAT) As the Engineering Graphics and Design (EGD) PAT is a compulsory national formal assessment task that contributes 25% (i.e. 100 marks) towards a learner's final NSC mark, it is essentially the third NSC examination paper of EGD. All the presentation requirements must therefore be adhered to and, with the exception of the required research, completed at school, under the supervision of the EGD teacher. Each learner must complete the PAT individually and ALL the presentations must be his/her own original work. The primary purpose of the EGD PAT is to assess four subjective content and concept topics which are not assessed in the examination papers. These are: • The design process • The application of drawing knowledge and drawing skills to the design process • CAD management and drawings • The quality and neatness of free-hand, instrument and CAD drawings It also provides an opportunity to: • Incorporate content & concepts that are outside/beyond the framework of the prescribed EGD content The EGD PAT is therefore designed to develop a learner's ability to integrate and apply knowledge and to demonstrate acquired levels of skills and competency. With the inclusion of the PAT into EGD, the learner is given an opportunity to apply acquired knowledge, skills and values in a creative way through the design process. The learner is given an opportunity to complete the PAT in an environment which is more conducive to the creative processes. This environment should therefore provide the learner with easier access to, and a wider variety of, resource material than would be available in a formal examination. The various components of the EGD PAT gives the learner an opportunity to demonstrate the level of drawing skill that has been attained in all the appropriate drawing methods through the presentation of the required drawings. Each EGD PAT consists of TWO parts: • Part A: The design process • Part B: Required working and pictorial drawings Part A of the PAT requires that the learner demonstrates a clear understanding of, and is able to apply, the design process. As part of the design process, the learner must be able to do the following: • Identify the problem(s) and formulate a design brief with specifications and constraints • Conduct and use relevant external research in an appropriate way • Generate a number of own ideas/concepts/solutions analytically and graphically through comprehensive free-hand drawings • Select a final solution(s) that demonstrates a clear understanding of the design brief • Present the final solution(s) as working drawings and pictorial drawings • Provide clear evidence of continuous self-evaluation during the development of the PAT Copyright reserved Please turn over Engineering Graphics and Design 4 GDE Gr. 10 & 11 PAT: 2015 & ► Part B of the PAT requires that the learner demonstrates and provides evidence of a acceptable level of knowledge and understanding of the concepts and content of Engineering Graphics and Design through the presentation of orthographic drawings and pictorial drawings. The PAT also gives the learner the opportunity to demonstrate that a high level of competency and skill has been attained in the following required EGD drawing methods: • Freehand drawings prepared in pencil • Instrument drawings prepared in pencil • Using a CAD (Computer-aided Drawing/Design) system NOTE: Each learner must complete one PAT for every year of the FET phase. However, by the end of the combined Grade 10 and Grade 11 cycle, each learner should have completed both a CIVIL and MECHANICAL PAT! This document contains SEVEN grade 10 and SEVEN grade 11 PAT scenarios. Templates for the development of own/new PAT scenarios are also included.

ADMINISTRATION OF THE PAT In accordance with the Annual Teaching Plan, every EGD learner must receives a copy of SECTION B’s general instruction and presentation requirements, the selected PAT scenario(s), the assessment criteria and rubrics, the grade specific summative assessment sheet and the declaration of authenticity. ALL the completed PATs must be submitted in time for summative assessment to be done before the commencement of provincial moderation. The PATs must therefore be completed in the following PHASES during the first three terms: Copyright reserved Please turn over Engineering Graphics and Design • • 5 GDE Gr. 10 & 11 PAT: 2015 & ► The GRADE 10 PHASES: Phase 1: Design Process (completed by the end of the 2nd term) Phases 2 and 3: Presentation Drawings and completion of portfolio (completed by the end of the 3rd term) The GRADE 11 PHASES: Phase 1: Design Process (completed by the end of the 1st term) Phase 2: Presentation Drawings (completed by the end of the 2nd term) Phase 3: Completion of portfolio (completed by the end of the 3rd term) NOTE: Although the phases could be done either CYCLICALLY or in BLOCK TIMES as indicated by the EGD CAPS, it is recommended that ONE ENTIRE DAY per term, e.g. as an extra paper during the June examinations, be allocated for each phase. GRADE 10 TIME ALLOCATION: The teaching/period time that may be allocated for the completion of the PAT is 8 hours to a maximum of 10 hours. Additional non-teaching/-period time may, however, also be allocated for the completion of the PAT at the school. However, the total maximum time for the completion of the PAT may not exceed 12 hours. GRADE 10 TIME ALLOCATION: The teaching/period time that may be allocated for the completion of the PAT is 10 hours to a maximum of 14 hours. Additional non-teaching/-period time may, however, also be allocated for the completion of the PAT at the school. However, the total maximum time for the completion of the PAT may not exceed 16 hours. To ensure that the PAT is completed within the prescribed phases and time frames, it is essential that the teacher draw up a pace setter/management plan, which must be aligned to the provincial management plan, for the learners at the beginning of the year. Attached to the pace setter/management plan must be target dates for the completion of the different components of the different phases. This will help learners to assess their own progress and teachers to set up intervention programmes. NOTE: • ALL the presentation requirements of the selected PAT must be adhered to and, with the exception of the required research, completed at school under guidance and supervision of the EGD teacher, who must observe the learners' progress at all times. Not adhering to this instruction will be deemed to be an examination irregularity. • It is the teacher's responsibility to ensure that each learner's PAT is of an appropriate higher-order complexity for the specific grade. 3. ASSESSMENT AND MODERATION OF THE PAT 3.1 Assessment Frequent developmental feedback is needed to guide and give support to each learner and to ensure that each learner is on the right track. Copyright reserved Please turn over Engineering Graphics and Design 6 GDE Gr. 10 & 11 PAT: 2015 & ► Both formal and informal assessment should be conducted throughout the development of the PAT. Informal assessment can be conducted by the learner, a peer, a group of learners or by the teacher. However, the teacher must conduct ALL the formal assessment, by using official summative assessment sheet, and record the results on onto the official mark sheets himself/herself. ALL the PATs must be submitted in time for final formal assessment to be done before the commencement of provincial moderation. Once ALL the PATs have been formally assessed, the teacher must retain ALL the PATs for the purpose of external moderation. All the PATs must also be retained at the school for the period of time as prescribed by the Provincial Departments of Education. 3.2 Moderation Monitoring and/or moderation of the PAT can take place at any time during the development of the PAT. ALL completed presentation requirements of the PAT must therefore always be available at the school. During a moderation process, the moderator will randomly select the PAT files/portfolios that will be moderated. To assist the process of the final provincial moderation, the teacher must supply the moderator with a completed mark sheet(s) and a merit list(s). During the moderation process, learners may be called upon to explain the functions and principles of operating a CAD system and to demonstrate drawing skills through performing capability tasks. 3.3 Declaration of authenticity Prior to the final submission of the PAT for formative assessment, ALL the learners and teacher must complete the Declaration of Authenticity as laid out on the final page of this document. NOTE: Only the official grade specific SUMMATIVE ASSESSMENT SHEET (page 33 or 34) and the completed DECLARATION OF AUTHENTICITY form (page 35) of this document must be included in the front of the learner's completed PAT file/portfolio. 4. CONCLUSION Upon completion of the Practical Assessment Task learners should be able to demonstrate a better understanding of the industry, enhance their knowledge, skills, values and reasoning abilities as well as establish connections to life outside the classroom and address real-world challenges. The PAT furthermore develops learners' life skills and provides opportunities for learners to engage in their own learning.

A SIMPLIFIED RUBRIC FOR THE ALLOCATION AND VERIFICATION OF MARKS NOTE: • This rubric should be used to allocate marks for all aspects of the assessment criteria which require a mark out of 10. • This rubric should also be used to verify that the overall level of achievement, i.e. the final mark out of 10, of each assessment criteria is in accordance with the presentation requirement. • The concept of 'bench marking', i.e. the identification and mark allocation of the best example(s) for each assessment criteria, should be applied when assessing the PATs. MARK ALLOCATION for all assessment criteria of the PAT DESCRIPTION FOR MARK GENERAL INDICATOR ±% MARK ALL/MORE than ALL the REQUIREMENTS are met. - PERFECT - Error free 100% 10 ALL (ALMOST ALL) the REQUIREMENTS are met. - OUTSTANDING - Very few errors 90% + 9 ALMOST ALL (MOST OF) the REQUIREMENTS are met. - VERY GOOD - Few errors 80% + 8 70% + 7 The REQUIREMENTS are ADEQUATELY met. - SATISFACTORY - 60% + 6 The REQUIREMENTS are MODERATELY met. - ACCEPTABLE - 50% + 5 40% + 4 The REQUIREMENTS are SUBSTANTIALLY met. - GOOD - Some errors Many errors ONLY SOME of the REQUIREMENTS are met. - UNACCEPTABLE VERY FEW of the REQUIREMENTS are met. - NOT ACHIEVED - Mostly wrong The REQUIREMENTS are NOT met. - VERY POOR - Completely wrong NOT DONE!
