Downloaded from hlayiso.com Agricultural Technology 3 DBE/2021 Examination Guidelines 1. INTRODUCTION The Curriculum and Assessment Policy Statement (CAPS) for Agricultural Technology outlines the nature and purpose of the subject Agricultural Technology. This guides the philosophy underlying the teaching and assessment of the subject in Grade 12. The purpose of these Examination Guidelines is to:  Provide clarity on the depth and scope of the content to be assessed in the Grade 12 National Senior Certificate Examination in Agricultural Technology.  Assist teachers to adequately prepare learners for the examinations. This document deals with the final Grade 12 external examinations. It does not deal in any depth with the school-based assessment (SBA), practical assessment tasks (PATs) or final external practical examinations, as these are clarified in a separate PAT document which is updated annually. These Examination Guidelines should be read in conjunction with:  The National Curriculum Statement (NCS) Curriculum and Assessment Policy Statement (CAPS): Agricultural Technology  The National Protocol of Assessment: An addendum to the policy document, the National Senior Certificate: A qualification at Level 4 on the National Qualifications Framework (NQF), regarding the National Protocol for Assessment (Grades R–12)  The national policy pertaining to the programme and promotion requirements of the National Curriculum Statement, Grades R–12 Copyright reserved Please turn over

Downloaded from hlayiso.com Agricultural Technology 7 DBE/2021 Examination Guidelines EXAMPLES OF ASSESSMENT TASKS IN AGRICULTURAL TECHNOLOGY Control Tests  The control test in Agricultural Technology must be substantive in terms of time and marks.  Minimum 75–100 marks with a duration of 2 hours  Tests should include the theory of the technological process, principles and concepts and the application thereof in the production of product/artefact. Research Task  This task should be based on activities such as research, case study, projects, simulations, modelling, fabrication, manufacturing and demonstration and should focus on a variety of technological themes relating to an agricultural context.  Minimum marks for the research task must be 100 marks.  Tasks such as simulations put theoretical knowledge to practical use and usually do not require conclusions.  Therefore, simulations will not include elaborate worksheets and conclusions but should rather generate guidelines and criteria to what is required. Examples of Research Tasks: Grade 12  Research on the maintenance of an electric fence  Set up a small-scale solar panel system on the farm  Research on a centre-pivot irrigation system Trial Examinations  The trial examinations for Grade 12 should consist of one paper of six questions and will count 200 marks.  The suggested duration of the paper is 3 hours. ALL the questions are COMPULSORY.  The trial examination needs to be closely related to the final examination in terms of time allocation, layout of the paper and subject requirements. External assessment in Grade 12 The external assessment task in Grade 12 consists of an externally written paper (50%) and a PAT (25%). November External Examination NSS  The external examination for Grade 12 will consist of one paper that contains six questions and counts 200 marks.  The duration of the paper will be 3 hours. ALL the questions are COMPULSORY.  The examination papers should test the knowledge and skills covered in Agricultural Technology. EXAMINATION GUIDELINES FOR AGRICULTURAL TECHNOLOGY General remarks: These guidelines are applicable to Grade 12 in Agricultural Technology. Specifications One paper Grade 12 Trial Examinations Duration: 3 hours Marks: 200  All the questions must be answered.  Sketches must be neat.  All calculations and units must be indicated.  The questions will not necessarily count for the same marks, as each section of the work has a different weighting.

GENERAL INFORMATION 4.1 Quantities, symbols and units The most common quantities, symbols and SI units used in introductory physics are listed below. A quantity should not be confused with the unit in which it is measured. 4.1.1 Formulae  Determining the speed of a pulley Na X Da = Ng X Dg Na = speed of drive pulley Da = diameter of drive pulley Ng = speed of driven pulley Dg = diameter of driven pulley Example: The sketch below shows an electric motor connected to a pulley with a fan belt. The pulley diameter on the electric motor is 70 mm and the turning speed is 4 000 revolutions per minute. The pump that is connected to the driven pulley requires a speed of 2 000 revolutions per minute. Calculate the diameter of the driven pulley by using the formula below. Show ALL calculations. Na x Da = Ng x Dg Where: Na = Speed of driving pulley D = Diameter of driving pulley a Ng = Speed of driven pulley Dg = Diameter of driven pulley Na x Da = Ng x Dg 4 000 x 70 = 2 000 x Dg Dg = 4 000 x 70 2 000 Driven pulley diameter Dg = 140mm (5 marks) Copyright reserved Please turn over

(Show all calculations.) Gear Ratio = Drive gear Driven gear = 54 18 The gear ratio is 1:3 (3 marks)  Calculate the flow rate in a water system Flow rate = Content Time Example Calculation of the flow rate (litres per minute) by using the data below: (Show all calculations) The capacity of the tank is 20 k ℓ It took 40 minutes to fill the tank to the top. Flow rate = capacity Time = 20 x 1000 40 = 20000 40 = 500 ℓ/minute (4 marks) 4.1.2 Units and their symbols Metals  Copper Cu  Tin Sn  Zinc Zn  Brass Cu Zn  Bronze Cu Sn Synthetic materials  Glass fibre  Vesconite  Teflon Copyright reserved Please turn over

CONCLUSION It is envisaged that this Examination Guidelines document will serve as an instrument to strengthen and empower teachers to set valid and reliable assessment items in all their classroom activities. This Examination Guidelines document is meant to articulate the assessment aspirations espoused in the CAPS document. It is therefore not a substitute for the CAPS document which teachers should teach to. Qualitative curriculum coverage as enunciated in the CAPS cannot be over-emphasised. Copyright reserved
