    SIJIL TINGGI PERSEKOLAHAN MALAYSIA

    (MALAYSIA HIGHER SCHOOL CERTIFICATE EXAMINATION)

    BIOLOGY Syllabus and Specimen Papers

    This syllabus applies for the 2012/2013 session and thereafter until further notice.

    MAJLIS PEPERIKSAAN MALAYSIA

    (MALAYSIAN EXAMINATIONS COUNCIL)

  • NATIONAL EDUCATION PHILOSOPHY

    “Education in Malaysia is an on-going effort towards further

    developing the potential of individuals in a holistic and

    integrated manner, so as to produce individuals who are

    intellectually, spiritually, emotionally and physically

    balanced and harmonious, based on a belief in and devotion

    to God. Such effort is designed to produce Malaysian

    citizens who are knowledgeable and competent, who possess

    high moral standards, and who are responsible and capable

    of achieving a high level of personal well-being as well as

    being able to contribute to the betterment of the family, the

    society and the nation at large.”

  • FOREWORD

    This revised Biology syllabus is designed to replace the existing syllabus which has been in use since

    the 2001 STPM examination. This new syllabus will be enforced in 2012 and the first examination

    will also be held the same year. The revision of the syllabus takes into account the changes made by

    the Malaysian Examinations Council (MEC) to the existing STPM examination. Through the new

    system, the form six study will be divided into three terms, and candidates will sit for an examination

    at the end of each term. The new syllabus fulfils the requirements of this new system. The main

    objective of introducing the new examination system is to enhance the teaching and learning

    orientation of form six so as to be in line with the orientation of teaching and learning in colleges and

    universities.

    The revision of the Biology syllabus incorporates current developments in biology studies to be more

    relevant to the current global developments. Biology is a science that deals with the study of living

    organisms. It is dynamic and affects every aspect of our daily lives, from food and health, to the

    responsibilities towards our environment. The cumulative discoveries and developments in biology

    have tremendously enhanced our understanding and perception towards both the unity and diversity of

    life. With this understanding, we have become more aware of our interdependence with our rich

    biodiversity and natural resources. The application of biology together with modern technologies

    leads to the evolution of biotechnology. Furthermore, the assessment tools of this syllabus consist of

    written papers and coursework. The written papers evaluate candidates’ knowledge and understanding

    of the subject, while the coursework provides an opportunity for candidates to trigger their inquisitive

    biological reasoning. This also enhances their understanding and application of biological sciences

    and develops the candidates’ soft skills.

    The syllabus contains topics, teaching periods, learning outcomes, examination format, grade

    description and specimen papers.

    The design of this syllabus was undertaken by a committee chaired by Professor Emeritus Dato’ Dr.

    Latiff bin Mohamad from Universiti Kebangsaan Malaysia. Other committee members consist of

    university lecturers, representatives from the Curriculum Development Division, Ministry of

    Education Malaysia, and experienced teachers who are teaching Biology. On behalf of MEC,

    I would like to thank the committee for their commitment and invaluable contribution. It is hoped that

    this syllabus will be a guide for teachers and candidates in the teaching and learning process.

    The Practical Syllabus

    School-based Assessment of Practical

    School-based assessment of practical work will be carried out throughout the form six school terms

    for candidates from government schools and private schools which are approved by the MEC to carry

    out the school-based assessment of practical work.

    MEC will determine 15 compulsory experiments to be carried out by the candidates and to be

    assessed by the subject teachers in the respective terms. Details of the title, objective, learning

    outcome, introduction, material, apparatus and procedure of each of the experiments will be specified

    in the Teacher’s and Student’s Manual for Practical Biology which can be downloaded from MEC’s

    Portal (http://www.mpm.edu.my) by the subject teacher during the first term of form six.

    Candidates should be supplied with a work scheme before the day of the compulsory experiment

    so as to enable them to plan their practical work. Each experiment is expected to last one school

    double period. Assessment of the practical work is done by the subject teachers during the practical

    sessions and also based on the practical reports. The assessment should comply with the assessment

    guidelines prepared by MEC.

    A repeating candidate may use the total mark obtained in the coursework for the subsequent

    STPM examination. Requests to carry forward the moderated coursework mark should be made

    during the registration of the examination.

    During the practical session, candidates should be able to:

    (a) make observations on living, preserved specimens and models, and record them accurately

    in writing or by using clear drawings or diagrams,

    (b) identify morphological features of specimens as a basis for their classification,

    (c) carry out dissection, display and illustrate the result,

    (d) stain and mount specimens for microscopic examination,

    (e) identify and illustrate the specimens observed under light microscope,

    (f) carry out biochemical, physiological and genetic experiments,

    (g) carry out sampling for ecological studies,

    (h) record the results systematically, interpret the data scientifically and make conclusion.

    Written Practical Test

    The main objective of written practical test is to assess the candidates’ understanding of practical

    procedures in the laboratory.

    The following candidates are required to register for this paper:

    (a) individual private candidates,

    (b) candidates from private schools which have no permission to carry out the school-based

    assessment of practical work,

    (c) candidates who repeat upper six (in government or private schools),

    (d) candidates who do not attend classes of lower six and upper six in two consecutive years

    (in government or private schools),

    (e) candidates who take Biology other than the package offered by schools.

    Three structured questions related to practical work will be set. MEC will not be strictly bound by

    the syllabus in setting questions. Where appropriate, candidates will be given sufficient information to

    enable them to answer the questions. Only knowledge of theory within the syllabus and knowledge of

    usual laboratory practical procedures will be expected.

    Candidates should have sufficient knowledge on:

    (a) structure of specimens and record them accurately in writing or illustration,

    (b) morphological and anatomical features and relate to functions of specimens as a basis for

    their classification,

    (c) dissection of specimens and illustration of the result (rat),

    (d) staining and mounting specimens for microscopic examination,

    (e) identification and illustration of the specimens as observed under microscope,

    (f) biochemical, physiological and genetic experiments,

    (g) sampling for ecological studies,

    (h) interpreting, evaluating, drawing conclusion from experimental data,

    (i) using theories to explain the results of experiments and performing simple calculations

    based on experiments.
