LEAVING CERTIFICATE PROGRAMMESAims and Principles1. The general aim of education is to contributetowards the development of all aspects of theindividual, including aesthetic, creative, critical,cultural, emotional, expressive, intellectual, forpersonal and home life, for working life, for living in the community and for leisure.2. Leaving Certificate programmes are presentedwithin this general aim, with a particular emphasis on the preparation of students for therequirements of further education or training, foremployment and for their role as participative,enterprising citizens.3. All Leaving Certificate programmes aim to provide continuity with and progression from theJunior Certificate programme. The relativeweighting given to the various components —e.g. personal and social (including moral andspiritual) development, vocational studies andpreparation for further education and for adultand working life — within the programmes mayvary.4. Programmes leading to the award of the LeavingCertificate are of two years duration and areoffered in three forms:i. The Leaving Certificate (Established)ii. The Leaving Certificate Vocational Programmeiii. The Leaving Certificate Applied5. All Leaving Certificate programmes, in contributing to a high quality education, emphasise theimportance of : self-directed learning and independentthought a spirit of inquiry, critical thinking, problemsolving, self-reliance, initiative and enterprise preparation for further education, for adultand working life lifelong learning.The Leaving Certificate (Established)The Leaving Certificate (Established) programmeoffers students a broad and balanced educationwhile allowing for some specialisation.Syllabuses are provided in a wide range of subjects. All subjects are offered at Ordinary andHigher levels. In addition, Mathematics and Irishare also offered at Foundation level.The certificate is used for purposes of selectioninto further education, employment, training andhigher education.The Leaving Certificate VocationalProgramme (LCVP)The Leaving Certificate Vocational Programme isan intervention within the Leaving Certificate(Established). LCVP students study a minimumof five subjects (at Higher, Ordinary orFoundation levels), including Irish and two subjects from specified vocational subject groupings.They are also required to take a recognisedcourse in a Modern European language, otherthan Irish or English. In addition LCVP studentstake three Link Modules on Enterprise Education,Preparation for Work and Work Experience.In particular, the LCVP aims to foster in studentsa spirit of enterprise and initiative and to develop their interpersonal, vocational and technological skills.The Leaving Certificate AppliedThe Leaving Certificate Applied is a distinct, selfcontained Leaving Certificate programme. It isdesigned for those students who do not wish toproceed directly to third level education or forthose whose needs, aspirations and aptitudesare not adequately catered for by the other twoLeaving Certificate programmes. The LeavingCertificate Applied is structured around threemain elements – Vocational Preparation,Vocational Education and General Education which are interrelated and interdependent. Thisprogramme is characterised by educational experiences of an active, practical and student-centred nature.

L E A V I N G C E R T I F I C AT E P H Y S I C S S Y L L A B U S PreamblePolicy ContextScience education in the senior cycle should reflectthe changing needs of students and the growingsignificance of science for strategic development inIreland.Leaving Certificate science syllabuses are designed toincorporate the following components: science for the enquiring mind, or pure science, toinclude the principles, procedures and concepts ofthe subject as well as its cultural and historicalaspects science for action, or the applications of scienceand its interface with technology science, which is concerned with issues – political,social and economic – of concern to citizens.The three components should be integrated withineach science syllabus, with the first componenthaving a 70% weighting. The remaining 30% shouldbe allocated to the other two components in the ratio3 to 1.The syllabuses, which are offered at two levels,Higher and Ordinary, will have approximately 180hours of class contact time over a two-year period.They should be practically and experimentally basedin their teaching.

L E A V I N G C E R T I F I C AT E P H Y S I C S S Y L L A B U S IntroductionAimsThe aims of the syllabus, common to both levels,The science, technology and society (STS)component places the content within a relevantcontext. The format in which the syllabus is presenteddoes not imply any particular order of teaching.Teaching strategies should promote, in a positivemanner, the aims and objectives of the syllabus.are: to give students an understanding of thefundamental principles of physics and theirapplication to everyday life and technology to develop an appreciation of physics as a humanendeavour, thereby enriching the students’Activities describe how the syllabus objectives are tobe achieved as the content is studied. The activitiescolumn provides a pedagogical approach to thesyllabus by outlining the relevant demonstrations andby indicating where problem-solving is required.Where resources permit, the use of spreadsheets, datalogging, computer-aided learning, modelling andsimulation is recommended. Slides, posters andvideos are excellent resource materials, and their usein implementing the syllabus is recommended.Additional activities may be included whereappropriate.experience of life to provide a reasonably broad perspective ofphysics, thus developing an understanding of thephysical environment and of how human beingsinteract with it to provide a general education in physics for allstudents, whether or not they proceed to furtherstudies in physics to develop the ability to observe, to thinklogically, and to communicate effectively to develop an understanding of the scientificmethodThe science, technology and society (STS)component places the concepts, principles andtheories of physics within relevant contexts by(a) referring to the applications of physics and(b) solving problems set in the everyday world.It is important to include personal, medical,biological and social examples of physics as well asmechanical or technical examples, so that the place ofphysics in the everyday world can be appreciated.Establishing links with local industry would be ofgreat importance in implementing this aspect of thesyllabus. The links between history, culture,philosophy and physics should also be included.Students, through their study of physics, shoulddevelop a critical awareness of the limitations of, andconstraints on, physics. Therefore, as citizens, theycan contribute constructively to the development oftheir society on social, economic and environmentalissues, some of which may be controversial. to develop an appreciation of physics as acreative activity, using informed intuition andimagination to create an understanding of thebeauty, simplicity and symmetry in nature.Structure of the SyllabusThe entire Ordinary level syllabus is presented firstfollowed by the entire Higher level syllabus. Thesyllabus is presented in four columns: content depth of treatment activities science, technology, and society (STS).The content and the depth of treatment required arestated. The activities given in the syllabus provideopportunities to achieve the objectives of the syllabus.2

L E A V I N G C E R T I F I C AT E P H Y S I C S S Y L L A B U S laboratory. Those required are indicated in theactivities column by the term “demonstration ofeffect”.STS is an integral part of the syllabus at bothOrdinary and Higher levels, so that students canplace physics within the everyday world. The STSmaterial needs to be known at the appropriate level;that is, where the basic principle is on the Ordinarylevel, examples must be known at Ordinary level, andsimilarly at Higher level. Only the principles of theapplications listed in STS are required. Technicaldetails, e.g. structural details, operational details, etc.,are not required. The list of applications is notexhaustive and additional applications may beincluded where appropriate.Experimental error: There should be an appreciation of the errors inherent in an experiment and ofthe precautions that can be taken to reduce sucherrors. No quantitative treatment is required.Differentiation between Higher leveland Ordinary levelThere are three main differences between Higher leveland Ordinary level: structure and contentThe mathematical requirements are stated on pages45 and 46. The notation and symbols to be used aredefined on pages 47 to 51 and the formulas sectionon pages 52 to 54 indicates the equations relevant tothe syllabus. depth of treatment mathematical treatment.Structure and content: Ordinary level consists of adefined set of concepts. Higher level consists of theOrdinary level concepts, additional concepts, andeither Option 1 (Particle Physics) or Option 2(Applied Electricity). The additional concepts atHigher level are printed in black text.Practical workStudents must follow a course of practical work. Theexperiments listed at the end of each section of thesyllabus must be carried out by the students and anadequate record of such work must be retained forthe period of the course.Depth of treatment: Ordinary level provides anoverview of physics and its applications to everydaylife, while at Higher level there is a deeper, morequantitative treatment of physics.Standard laboratory safety precautions must beobserved, and due care must be taken whencarrying out all experiments.Mathematical treatment: Equations must beknown and used at Ordinary level. At Higher levelcertain equations must be derived; the other equations must be known and used. The formulas section(pages 52 to 54) indicates the equations relevant tothe syllabus. Appropriate calculations are essentialthroughout to develop students’ skills and understanding.The hazards associated with electricity, EHT, lasersetc. should be identified where possible, andappropriate precautions taken. The careful use ofsources of ionising radiation is essential. It isimportant that teachers follow guidelines issued bythe Department of Education and Science.It is recommended that the practical work listed inthe syllabus be supplemented by teacherdemonstrations, further student practical work, andstudent investigations, as appropriate. Where possible,physical phenomena should be demonstrated in the3

All material within the syllabus isexaminable.It should be noted that STS is examinable. Studentswill be expected to have a knowledge of generalapplications but will not be required to have adetailed knowledge of specific applications.Practical work is an integral part of the study ofphysics; it will initially be assessed through themedium of the written examination paper. Anelement of practical assessment may be included aspart of the overall assessment at a later stage.4
