Students will be introduced to the Construction related syllabi at senior cycle level and develop strategies to teach their concepts and content. Students will draw on their knowledge base from their primary degree and content of this module to formulate a coherent approach to teaching construction based subjects at second level.
In addition to the Construction syllabi students will be involved in extensive laboratory work to ensure the competent and effective implementation of wood processing safety and practice in second level technology education settings. This is a core issue regarding the management of the classroom environment for health and safety of all and the nature of work being conducted.

Introduction:Aim & Objectives…The overall aim of this module is to prepare you for the role of teaching, learning and assessment of second level leaving certificate Construction Studies.
Affective Domain: To motivate and foster your moral development as a teacher of Construction Studies with emphasis on critical pedagogy and practice, i.e. health & safety, through the integration of previous knowledge and methods of reflective inquiryCognitive Domain: To draw on the learning obtained from your pervious qualifications to support the development of your knowledge, comprehension and application of both theoretical and practical elements of Constructions StudiesPsychomotor Domain:To foster your ability to plan, develop and demonstrate practical processes and techniques through organised teaching and learning activities in the Construction Studies setting

60% Laboratory Work (LW) 20% Written Exam (WE) 20% Term Assignments (TA) Machines Practical Exam (Pass / Fail Basis) Lab Book (Pass / Fail Basis) Note:
Students must pass all assessment elements to obtain a pass in the module. Students that fail the practical machines exam and repeat exam will
automatically fail the entire module.

Construction Studies:Details: Construction Studies (C.S.) was established in 1984 and was first
introduced to vocational schools It is a second level senior cycle subject and a follow on subject from
junior certificate Materials Technology Wood (MTW) It is part of the ‘established leaving certificate’ programme The subject is optional, meaning students can choose to study it if they
wish. It is offered in most schools but not all. It offers a broad range of learning involving both theory and practical. In terms of its assessment, it is offered at both ordinary and higher level The uptake in C.S. has continued despite the collapse of the Irish
Construction sector/Industry. This can be largely attributed to the learning experience on offer and the
respect for teachers of C.S.

Construction Studies:Current Trends…Current Trends: Though the theoretical areas/principles of the subject remain the same there has been a
significant change in the process of building. This is currently being assessed in the leaving certificate exam, which is set by the State
Examinations Commission (SEC). The subject has engendered a strong theme for economic, social and environmental
building performance, i.e. sustainability. These features are being integrated into the examination phase through elements such
as updated building regulations, building energy rating (BER), passive housing, sustainable planning and development.
A few years ago the subject was to receive a formal update including a revised syllabus and new name –Architectural Technology.
However, the current economic climate and the issue of funds to support the broader range of development in the technologies has resulted in this plan being shelved until a future date.

• Section 8(2)e of the 2005 Act states that it is the duty of every employer“to provide systems of work that are planned, organised, performed and maintained so as to be, so far as is reasonably practicable, safe and without risk to health.”
• Health and safety management is a practical and systematic approach to identifying hazards and evaluating the extent of associated risk

• Hazard • means anything that can cause harm (eg
chemicals, electricity, working from ladders, etc)
• Risk • is the chance, high or low, that
somebody will be harmed by the hazard.

The CE Marking is not a mark indicating conformity to a standard but rather a mark indicating conformity to the legal requirements of EU Directives.

• CE Marking is the symbol as shown on the top of this page. • The letters "CE" are the abbreviation of French phrase
"Conformité Européene" which literally means "European Conformity". • The term initially used was "EC Mark" and it was
officially replaced by "CE Marking" in the Directive 93/68/EEC in 1993.

• Machinery must bear the “CE” mark in order to be deemed in compliance with these regulations.
• Must not add to machinery – must be there… criminal offence to try to add it.
• Also an offence to reduce the visibility of the “CE” Marking on a machine.

The existence of the “CE” marking on a piece of machinery should indicate that its manufacturer has met all relevant standards and requirements.

Step 1:Isolate machine
Step 2: Squaring guide fence• Set up surface planer guide fence @ 90⁰ to
table surface• Note infeed and outfeed table. • Square to infeed using right angle square.• Use red lock handles to open and adjust fence.• Lock gently when fence is perpendicular to
infeed table.

Step 3: Setting infeed dept• This machine is calibrated in metric.• Maximum recommended material removal
is 1-2mm/pass• Dept stop to be set at 2mm• Open infeed lock handle• Turn wheel to left to drop table to 2mm• Lower you drop, the more the planer
cutting block is exposed• Close infeed lock handle when required
dept is achieved.• * Do not adjust outfeed table level, this is
for maintenance purposes only*

Step 4: Setting the guide fence width• Minimum blade exposure• Width of material + 10mm is recommended• This results in 10mm blade exposure - Safety• Adjust lock handle to wind in or out guide fence• Lock in appropriate position

Step 5: Guard adjustment• Guard set for face side = handle up – 10mm
blade exposure• Guard set for face edge = handle flat – no blade
exposure

Step 6: Material Inspection• Inspect material for the following defects
• Cupping• Bowing• Twist• Knots• Loose grain
• Example - if material is bowed, set the bowed face to the surface planer table surface and process. Material should never be run through hump side down.

Step 7: Determining face side and face edge• Use machine surface to check square• Select appropriate face side and face edge
based on inspection• Preliminary surface marking using an ‘X’ with
no less than a HB pencil• Ensure extraction gate valve is open and
extraction is on• Proceed to plane material – face side and face
edge only! Gate Valve locate on extractor pipe just above surface planer

1. Unlock twist release stop mechanism2. Press green button to start3. Allow machine to build up, this can be determined by
noise consistency4. When noise is consistent flip delta switch to on position5. Feed rate, i.e. Speed at which material is passed, is set.6. Adjust table height as required7. Feed material as directed

Refer back to your cutting list to make sure you cut pieces to the correct length.
After the material has been ripped and surface planned into correct / required sizes, you then have to cross-cut the sections to the required length. For this, you will have to set up the fence on the sliding table to achieve this.
