Syllabus and Specimen Papers

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

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.

22

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.
