+ IITIOIllE FORTIACHINGTECHNICIl DIIWING

It is generally recognised that Technical Drawing is the language of communication oftechnical/vocational occupations and as such, has widespread applications in the life ofconsumers. It is, therefore, being recommended that every secondary school student should have,at the minimum, a basic knowledge of Technical Drawing.

To this end, the Caribbean Examinations Council recognizes the need to provide a programme ofstudies in Technical Drawing which will cater not only to the above stated interest, but also tothose students who will proceed to studies at tertiary levels and/or seek entry level employmentin related fields.

The Technical Drawing course as conceived, therefore, will be an essential companion to thecognate CSEC Industrial Technology programme as well as an integral component of the GeneralEducation curriculum.

+ GENEIIlOBJECTIVESThis syllabus is designed for candidates to:

(i) develop an understanding of and appreciation of Technical Drawing in the CaribbeanIndustrial Society;

II (ii) discover and develop their talents in the fields of Technical Drawing and relatedtechnologies;

(iii) develop technical problem-solving skills in Technical Drawing as related to materialsandprocesses;

(iv) develop the correct and accepted Technical Drawing skills as demanded by Industry;

(v) be aware of the career opportunities available in Technical Drawing and its related fields;

(vi) have a working knowledge and understanding of Computer Aided Drafting applications;

~ ICXC 13/0 ISYLL OO/A.

CANDIDATE POPULATION

The syllabus is designed to be covered in the final two years of the five-year secondary schoolprogramme and is intended for students enrolled in a full-time programme. However, candidateswho do not attend school full-time may undertake the course by observing the followingguidelines:

A. Regulations for Private Institutions

(i) Candidates entering for the examination through private institutions recognizedby the Council will be required to complete all the components of the respectiveproficiencies.

(ii) The School-Based Assessment of such candidates must be monitored by thetutors in the institution through which they register.

B. Regulations for Private Candidates

(i) "A private candidate is one not entered through a school or other approvededucational institution".

(ii) A private candidate will be required to complete all the components of therespective proficiencies.

(iii) A private candidate must identify a teacher/tutor from a registered institution(school/technical institute/community college) who will assess and approve thecandidate's submission for the School-Based Assessment component of thesyllabus. The name, school, and territory of the identified teacher/tutor should besubmitted to the Council on registration for the subject.

ALLIED SUBJECTS

School candidates should be encouraged to include the following subjects in their programme of IIstudy: one of the Industrial Technology subjects (Building Technology; Mechanical EngineeringTechnology; Electrical and Electronic Technology), English A, Mathematics, Physics.

SUGGESTED TIME ALWCATION

lilt is recommended that a minimum of five 4O-minute periods per week with no single period be II

allocated to the subject over a two-year period.

~ ICXC 13/0 ISYLL OO/A. 2

+ IRIIIIIIIIIIIIF THESBIIBOSThe syllabus is divided into three Units:

UNIT 1UNIT 2UNIT 3

Plane and Solid GeometryBuilding DrawingMechanical Engineering Drawing

Candidates are expected to undertake UNIT 1: Plane and Solid Geometry and EITHER UNIT2: Building Drawing OR UNIT 3: Mechanical Engineering Drawing.

CERTIFICATION AND DEFINITION OF PROFILES

The Technical Drawing course is an integral component of the TechnicalNocational Educationprogramme offered by the Council. It will, therefore, be examined for certification at both Basicand General Proficiencies. Candidates have the option of using either the Traditional DrawingMethod (drawing board and tee square) or Computer Aided Drafting method/applications tocomplete the objectives of the syllabus.

Candidates will be awarded an overall grade reported on a 6-point scale, that is, Grades 1-6. In IIaddition to the overall grade, candidate's performance will also be reported under the profiledimensions, Knowledge, Application and Practical Ability.

DEFINITIONS

Knowledge Recall and comprehension of terms, principles, methods, theoriesand structures; interpretation and extrapolation;

Application Use of concepts, principles, methods and theories to solveproblems in a given situation; analysis, synthesis and evaluation;

Practical Ability Demonstration of manipulative skills involving the use ofdrawing instruments, equipment and materials in problemsolving situations.

(Distinction between Basic and General Proficiency)

The Basic Proficiency or "Core" syllabus provides the minimum Technical Drawing skills andcompetencies.

For the General Proficiency, the syllabus is augmented by additional modules to ensure a more-extensive knowledge and understanding of the subject. General Proficiency candidates willnormally be expected to proceed to further studies in their chosen subject areas and should beable to respond at a higher level to any of th.e modules listed in the syllabus, so as to demonstratetheir ability to recall and apply the knowledge gained in the solution of problems of a practicalnature.


Accordingly, the examinations for Basic Proficiency and General Proficiency differ in:

(i) the extent of the syllabus content to be covered;

(ii) the degree of difficulty of questions in papers other than Paper 1;

(iii) the relative importance of the three profile dimensions - Knowledge, Application,Practical Ability;

The syllabus coverage required is as follows:

• SCHOOL ..BASED ASSESSMENT

RATIONALE

School-Based Assessment (SBA) is an integral part of student assessment in the course covered by thissyllabus. It is intended to assist students in acquiring certain knowledge, skills and attitudes that areassociated with the subject. The activities for the SBA are linked to the syllabus and should form part ofthe learning activities to enable the student to achieve the objectives of the syllabus.

During the course of study for the subject, students obtain marks for the competence they develop anddemonstrate in undertaking their SBA assignments. These marks contribute to the final marks and gradesthat are awarded to students for their performance in the examination.

The guidelines provided in this syllabus for selecting appropriate tasks are intended to assist teachers andstudents in selecting assignments that are valid for the purpose of SBA. The guidelines provided for theassessment of the assignments are intended to assist teachers in awarding marks that are reliable estimatesof the achievement of students in the SEA component of the course. In order to ensure that the scoresawarded by teachers are consistent with the CXC standards, the Council undertakes the moderation of asample of the SBA assignments marked by each teacher.

School-Based Assessment provides an opportunity to individualise a part of the curriculum to meet theneeds of students. It f8cilitates feedback to the student at various stages of the experience. This helps tobuild the self-confidence of students as they proceed with their studies. School-Based Assessment alsofacilitates the development of the critical skills and abilities emphasised by this subject and enhances thevalidity of the examination on which candidate performance is reported. School-Based Assessment,therefore, makes a significant and unique contribution to both the development of relevant skills and thetesting and rewarding ofsrudents for the development olthose skills.

GENERAL PROFICIENCY

During the fourth and fifth terms of the course, candidates will be required to complete a project testingthe candidates' ability to design/redesign a Building component or Mechanical Engineering device/gadgetto solve a simple functional problem in one of the ten categories, namely:

Categories

i)ii)iii)iv)v)

HouseholdEducation facilitiesAgriculture/FishingHealth facilitiesTransportation

vi)vii)viii)ix)x)

Business/OfficePowerRecreationConstructionManufacturing

Candidates will be required to prepare a complete set of working drawings of the Building component orMechanical Engineering device/gadget. Sketches, working/assembly drawings should be kept in a portfolio(laboratory book) which will be assessed by the teacher. Candidates must include a full or part sectionalview of the fully assembled component or device/gadget for the Building or Mechanical Engineering Unit.The project will carry 60 marks - 6 for Knowledge, 24 for Application and 30 for Practical Ability and willaccount for 20% of the composite score (See page 4 of this document for detailed criteria and markscheme).

NB: The teacher should prepare candidates for the drawing project by discussing with them the stagesin the design process: recognition of need; definition of problem; illtLstration of various aspects ofsolution; selection of best solution; evaluation of selected solution; and presentation of chosensolution.

The drawing project must be doneIn its entirety in the classroom/laboratory. Since this project ispart of School-Based Assessment, it must be done under the gttidance of the teacher but must bethe candidate's own work.

Candidates who opt to use the Traditional Drawing Method for Paper 02 and Paper 03 may,nevertheless, opt to do the SBA drawing project tLsing the Computer Aided Draftingmethod/application.
