Year one consists of a series of modular topics which together lay the foundation for the following two years. While some of the topics are discrete most will be inter-dependent. At the core of the course are plane and descriptive geometries and communication Graphics. These expand to underpin a range of topics that increase in factor-of-difficulty over the three years. The course is so structured as to provide pupils with a stimulus for managing spatial problems mentally and communicating spatial ideas and solutions graphically.


(a)  To stimulate the pupils creative imagination through developing their visuo-spatial abilities.
(b)  To encourage the development of the cognitive and practical manipulative skills associated with graphicacy.
(c) To provide pupils with a body of knowledge appropriate to interpreting and communicating spatial information and ideas.
(d) To sharpen the pupils visual perception of their environment and its elements and encourage the exercising of aesthetic   value judgments.
(e)  To develop basic competency in computer graphics in the context of graphical problem-solving and computer aided design.
(f)  To encourage the development of logical and progressive reasoning and enquiry/investigative skills, and the ability to  spatialise and visualise two and three dimensional configurations and their elements in the solution of graphical problems.
(g)  To help pupils understand the importance of communicating information graphically.


The pupils will be able to:

• Use graphics in the development of ideas and in the communication of information.
• Interpret drawings and diagrams including freehand sketches, plans, numerical data (expressed graphically), flow charts and  formal working drawings.
• Solve two and three-dimensional space problems graphically using appropriate geometries and their underlying principles and  theorems.
• Demonstrate dexterity in the use of drawing instruments, templates etc. as reflected in neatness and accuracy.
• Display an understanding of the projection systems associated with descriptive geometry.
• Select appropriate methods of graphic representation in expressing spatial ideas and concepts.
• Show a basic understanding of input, processing and output systems associated with computers.
• Produce computer generated drawings and graphical solutions using appropriate computer graphics and computer aided design  software.
• Produce neat and accurate drawings according to recognised standards, conventions and illustration techniques.
• Co-operate in the assimilation of data necessary for scaled representation.
• Produce freehand drawings in two and three-dimensions as graphical communication and as an aid to spatial reasoning and  refinement.
• Recognise the importance of graphics in the process of designing and produce
graphical solutions to appropriate design problems.
• Use shade and colour with discretion and model appropriate solutions in card or other materials.
• Apply ergonomic and other appropriate data in the consideration and solution of design problems.

Subject Overview

Technical Graphics involves students in the development of the range of skills associated with the management of spatial problems and the graphical communication of spatial ideas and solutions.


Conventions and Standards

Plane Geometry:

•    Constructions
•    Plane figures
•    Loci
•    Transformation geometry
•    Areas and figures

Descriptive Geometry:

•    Orthographic Projection
•    Pictorial drawing and projection
•    Scaled drawing
•    Surface development

Communication Graphics:

•    Freehand drawing and sketching
•    Graphics in designing
•    Computer graphics



Technical Graphics is assessed at both Ordinary level and Higher level by means of a terminal examination paper. Teaching of this syllabus commenced in 1992. A review of provision for technology education in the junior cycle has taken place and syllabus revision will commence in 2006/2007

What sort of subject

Technical Graphics is one of the technology subjects offered at junior cycle. In Technical Graphics you will learn how to represent 3-D objects on paper. You will develop problem solving and creative thinking skills through the solution of graphical problems.

What will I learn in Technical Graphics?

Some of the things you will learn include:

•  How to produce drawings using drawing equipment, freehand sketches and computers
•  How to read and interpret drawings and diagrams
•  How graphics relate to the design and manufacture of products.

How will I learn Technical Graphics in school?

Some of the things you may do with your teacher and your classmates are:

•  produce neat drawings of everyday items
•  create models of recognisable items on the computer
•  use freehand sketching, colouring and shading to represent objects
•  make paper/cardboard cut-outs of items and use these to model items in 3-D
•  work on your own and as part of a group
•  use a textbook and worksheets
•  organise and maintain a folder of drawings and notes.

What is the Technical Graphics Junior Certificate exam like?

You will sit a three hour examination paper. It is made up two sections:

•  Short answer questions which you complete on the sheet provided and
•  Longer questions which require more detailed answers. The longer questions allow you to show, in greater detail, the drawing and problem solving skills you  have learned.

You can take the exam at Higher or at Ordinary level. When the time comes to decide, your teacher will help you choose the level that suits you best.

What sort of student

Technical Graphics helps you to think in a more logical and creative way. You will be able to communicate information using diagrams and sketches. You will have learned how to present information in a neat and organised fashion. This subject will be of use to you if you want to progress into career areas such as architecture or engineering.

A student with good spatial and good problem solving skills will do well- (technically minded). The subject is a must if a student is to choose its senior cycle equivalent subject, design and communication graphics after 3rd year.
