PREFACE
The aspiration of the nation to become an industrialised societydepends on science and technology. It is envisaged thatsuccess in providing quality science education to Malaysiansfrom an early age will serve to spearhead the nation intobecoming a knowledge society and a competitive player in theglobal arena. Towards this end, the Malaysian education systemis giving greater emphasis to science and mathematicseducation.
The Biology curriculum has been designed not only to provideopportunities for students to acquire science knowledge andskills, develop thinking skills and thinking strategies, and to
apply this knowledge and skills in everyday life, but also toinculcate in them noble values and the spirit of patriotism. It ishoped that the educational process en route to achieving theseaims would produce well-balanced citizens capable ofcontributing to the harmony and prosperity of the nation and itspeople.
The Biology curriculum aims at producing active learners. Tothis end, students are given ample opportunities to engage inscientific investigations through hands-on activities andexperimentations. The inquiry approach, incorporating thinkingskills, thinking strategies and thoughtful learning, should beemphasised throughout the teaching-learning process. Thecontent and contexts suggested are chosen based on theirrelevance and appeal to students so that their interest in thesubject is enhanced.
In a recent development, the Government has made a decision tointroduce English as the medium of instruction in the teachingand learning of science and mathematics. This measure willenable students to keep abreast of developments in science andtechnology in contemporary society by enhancing their capabilityand know-how to tap the diverse sources of information onscience written in the English language. At the same time, thismove would also provide opportunities for students to use theEnglish language and hence, increase their proficiency in thelanguage. Thus, in implementing the biology curriculum, attentionis given to developing students’ ability to use English for studyand communication, especially in the early years of learning.
The development of this curriculum and the preparation of thecorresponding Curriculum Specifications have been the work ofmany individuals over a period of time. To all those who havecontributed in one way or another to this effort, may I, on behalfof the Ministry of Education, express my sincere gratitude andthanks for the time and labour expended.

INTRODUCTION
As articulated in the National Education Policy, education inMalaysia is an on-going effort towards developing the potentialof individuals in a holistic and integrated manner to produceindividuals who are intellectually, spiritually, emotionally andphysically balanced and harmonious. The primary andsecondary school science curriculum is developed with the aimof producing such individuals.
As a nation that is progressing towards a developed nationstatus, Malaysia needs to create a society that is scientificallyoriented, progressive, knowledgeable, having a high capacity forchange, forward-looking, innovative and a contributor toscientific and technological developments in the future. In linewith this, there is a need to produce citizens who are creative,
critical, inquisitive, open-minded and competent in science andtechnology.
The Malaysian science curriculum comprises three core sciencesubjects and four elective science subjects. The core subjectsare Science at primary school level, Science at lower secondarylevel and Science at upper secondary level. Elective sciencesubjects are offered at the upper secondary level and consist ofBiology, Chemistry, Physics, and Additional Science.
The core science subjects for the primary and lower secondarylevels are designed to provide students with basic science
knowledge, prepare students to be literate in science, andenable students to continue their science education at the uppersecondary level. Core Science at the upper secondary level is
designed to produce students who are literate inscience, innovative, and able to apply scientific knowledge indecision making and problem solving in everyday life.
The elective science subjects prepare students who are morescientifically inclined to pursue the study of science at post-
secondary level. This group of students would take up careers inthe field of science and technology and play a leading role in thisfield for national development.
For every science subject, the curriculum for the year isarticulated in two documents: the syllabus and the curriculumspecifications. The syllabus presents the aims, objectives and theoutline of the curriculum content for a period of 2 years forelective science subjects and 5 years for core science subjects.The curriculum specifications provides the details of thecurriculum which includes the aims and objectives of thecurriculum, brief descriptions on thinking skills and thinking
strategies, scientific skills, scientific attitudes and noble values,teaching and learning strategies, and curriculum content. Thecurriculum content provides the themes, learning areas, learningobjectives, suggested learning activities, the intended learningoutcomes, notes and vocabulary.
AIMS
The aims of the biology curriculum for secondary school are toprovide students with the knowledge and skills in science andtechnology and enable them to solve problems and makedecisions in everyday life based on scientific attitudes and noblevalues.
Students who have followed the biology curriculum will have thefoundation in biology to enable them to pursue formal andinformal further education in science and technology.

THINKING SKILLS
Thinking is a mental process that requires an individual tointegrate knowledge, skills and attitude in an effort to understandthe environment.
One of the objectives of the national education system is toenhance the thinking ability of students. This objective can beachieved through a curriculum that emphasises thoughtfulllearning. Teaching and learning that emphasises thinking skillsis a foundation for thoughtful learning.
Thoughtful learning is achieved if students are actively involvedin the teaching and learning process. Activities should beorganised to provide opportunities for students to apply thinkingskills in conceptualisation, problem solving and decision-making.
Thinking skills can be categorised into critical thinking skills andcreative thinking skills. A person who thinks critically alwaysevaluates an idea in a systematic manner before accepting it. Aperson who thinks creatively has a high level of imagination, isable to generate original and innovative ideas, and modify ideasand products.
Thinking strategies are higher order thinking processes thatiinvolve various steps. Each step involves various critical andcreative thinking skills. The ability to formulate thinkingstrategies is the ultimate aim of introducing thinking activities inthe teaching and learning process.
Critical Thinking Skills
A brief description of each critical thinking skill is as follows:
Attributing Identifying characteristics, features,qualities and elements of a concept or an
object.Comparing andContrasting
Finding similarities and differences basedon criteria such as characteristics,features, qualities and elements of aconcept or event.
Grouping andClassifying
Separating objects or phenomena intocategories based on certain criteria suchas common characteristics or features.
Sequencing Arranging objects and information in orderbased on the quality or quantity of commoncharacteristics or features such as size,
time, shape or number.
Prioritising Arranging objects and information in orderbased on their importance or priority.
Analysing Examining information in detail by breakingit down into smaller parts to find implicitmeanings and relationships.
Detecting Bias Identifying views or opinions that have thetendency to support or oppose somethingin an unfair or misleading way.
Evaluating Making judgements on the quality or value
of something based on valid reasons orevidence.
Making Conclusions Making a statement about the outcome ofan investigation that is based on ahypothesis.

Creative Thinking Skills
A brief description of each creative thinking skill is as follows:
Generating Ideas Producing or giving ideas in a discussion.
Relating Making connections in a certain situationto determine a structure or pattern ofrelationship.
Making Inferences Using past experiences or previouslycollected data to draw conclusions andexplain events.
Predicting Stating the outcome of a future eventbased on prior knowledge gained throughexperiences or collected data.
MakingGeneralisations
Making a general conclusion about agroup based on observations on, orinformation from, samples of the group.
Visualising Recalling or forming mental images abouta particular idea, concept, situation orvision.
Synthesising Combining separate elements or parts toform a general picture in various formssuch as writing, drawing or artefact.
Making Hypotheses Making general statement about therelationship between manipulatedvariables and responding variables toexplain observations or events. Thestatements can be tested to determinevalidity.
Making Analogies Understanding abstract or complexconcepts by relating them to simpler orconcrete concepts with similarcharacteristics.
Inventing Producing something new or adapting
something already in existence toovercome problems in a systematicmanner.
Thinking Strategy
Description of each thinking strategy is as follows:
Conceptualising Making generalisations based on inter-related and common characteristics inorder to construct meaning, concept or
model.
Making Decisions Selecting the best solution from variousalternatives based on specific criteria toachieve a specific aim.
Problem Solving Finding solutions to challenging orunfamiliar situations or unanticipateddifficulties in a systematic manner.
Besides the above thinking skills and thinking strategies,another skill emphasised is reasoning. Reasoning is a skillused in making logical, just and rational judgements.Mastering of critical and creative thinking skills and thinkingstrategies is made simpler if an individual is able to reason inan inductive and deductive manner. Figure 1 gives a generalpicture of thinking skills and thinking strategies.

Figure 1: TSTS Model in Science Mastering of thinking skills and thinking strategies (TSTS)through the teaching and learning of science can bedeveloped through the following phases:
1. Introducing TSTS.2. Practising TSTS with teacher’s guidance.
3. Practising TSTS without teacher’s guidance.4. Applying TSTS in new situations with teacher’sguidance.
5. Applying TSTS together with other skills to accomplishthinking tasks.
Further information about phases of implementing TSTS canbe found in the guidebook “Buku Panduan Penerapan Kemahiran Berfikir dan Strategi Berfikir dalam Pengajaran dan Pembelajaran Sains” (Curriculum Development Centre,1999).
Relationship between Thinking Skills and Science ProcessSkills
Science process skills are skills that are required in theprocess of finding solutions to a problem or making decisionsin a systematic manner. It is a mental process that promotescritical, creative, analytical and systematic thinking. Masteringof science process skills and the possession of suitableattitudes and knowledge enable students to think effectively.
The mastering of science process skills involves themastering of the relevant thinking skills. The thinking skills

Teaching and Learning based on Thinking Skills andScientific Skills
This biology curriculum emphasises thoughtful learning based onthinking skills and scientific skills. Mastery of thinking skills andscientific skills are integrated with the acquisition of knowledge inthe intended learning outcomes. Thus, in teaching and learning,teachers need to emphasise the mastery of skills together withthe acquisition of knowledge and the inculcation of noble values
and scientific attitudes.
The following is an example and explanation of a learningoutcome based on thinking skills and scientific skills.

Example:
Learning Outcome:
Thinking Skills:
Compare and contrast animal cell andplant cell based on the structure andorganelles
Comparing and contrasting
Explanation:
To achieve the above learning outcome, knowledge on thestructure and organelles in animal and plant cells are learnedthrough comparing and contrasting. The mastery of the skill ofcomparing and contrasting is as important as the acquisition ofknowledge on animal and plant cells. This would enablestudents to understand topics on mitosis and meiosis.
SCIENTIFIC ATTITUDES AND NOBLE VALUES
Science learning experiences can be used as a means toinculcate scientific attitudes and noble values in students. Theseattitudes and values encompass the following:
? Having an interest and curiosity towards the environment.
? Being honest and accurate in recording and validating data.? Being diligent and persevering.
? Being responsible about the safety of oneself, others, andthe environment.
? Realising that science is a means to understand nature.
? Appreciating and practising clean and healthy living.
? Appreciating the balance of nature.
? Being respectful and well-mannered.
? Appreciating the contribution of science and technology.
? Being thankful to God.
? Having critical and analytical thinking.
? Being flexible and open-minded.? Being kind-hearted and caring.
? Being objective.? Being systematic.
? Being cooperative.
? Being fair and just.? Daring to try.
? Thinking rationally.
? Being confident and independent.
The inculcation of scientific attitudes and noble values generallyoccurs through the following stages:
? Being aware of the importance and the need for scientific
attitudes and noble values.? Giving emphasis to these attitudes and values.
? Practising and internalising these scientific attitudes andnoble values.
When planning teaching and learning activities, teachers need togive due consideration to the above stages to ensure thecontinuous and effective inculcation of scientific attitudes andvalues. For example, during science practical work, the teachershould remind pupils and ensure that they carry out experimentsin a careful, cooperative and honest manner.
Proper planning is required for effective inculcation of scientificattitudes and noble values during science lessons. Before thefirst lesson related to a learning objective, teachers shouldexamine all related learning outcomes and suggested teaching-learning activities that provide opportunities for the inculcation ofscientific attitudes and noble values.

Love and respect for theenvironment.
Being responsible for the safety ofoneself, others and theenvironment.
Appreciating the balance of nature.
Being systematic.
Being cooperative.
Inculcating Patriotism
The biology curriculum provides an opportunity for thedevelopment and strengthening of patriotism among students.For example, in learning about the process of colonization andsuccession in an ecosystem, students will learn about the richbiodiversity in the country, they will appreciate the diversity anduniqueness of this natural resource of the country and deepentheir love for the country.
TEACHING AND LEARNING STRATEGIES
Teaching and learning strategies in the biology curriculumemphasise thoughtful learning. Thoughtful learning is a processthat helps students acquire knowledge and master skills that willhelp them develop their minds to the optimum level. Thoughtfullearning can occur through various learning approaches such asinquiry, constructivism, contextual learning, and mastery learning.Learning activities should therefore be geared towards activatingstudents’ critical and creative thinking skills and not be confinedto routine or rote learning. Students should be made aware of the
thinking skills and thinking strategies that they use in theirlearning. They should be challenged with higher order questionsand problems and be required to solve problems utilising theircreativity and critical thinking. The teaching and learning processshould enable students to acquire knowledge, master skills anddevelop scientific attitudes and noble values in an integratedmanner.

Teaching and Learning Approaches in Science
Inquiry-Discovery
Inquiry-discovery emphasises learning through experiences.Inquiry generally means to find information, to question and to
investigate a phenomenon that occurs in the environment.Discovery is the main characteristic of inquiry. Learning throughdiscovery occurs when the main concepts and principles ofscience are investigated and discovered by studentsthemselves. Through activities such as experiments, studentsinvestigate a phenomenon and draw conclusions by themselves.Teachers then lead students to understand the science conceptsthrough the results of the inquiry. Thinking skills and scientificskills are thus developed further during the inquiry process.However, the inquiry approach may not be suitable for allteaching and learning situations. Sometimes, it may be moreappropriate for teachers to present concepts and principles
directly to students.
Constructivism
Constructivism suggests that students learn about somethingwhen they construct their own understanding. The importantattributes of constructivism are as follows:
? Taking into account students’ prior knowledge.
? Learning occurring as a result of students’ own effort.
? Learning occurring when students restructure theirexisting ideas by relating new ideas to old ones.
? Providing opportunities to cooperate, sharing ideasand experiences, and reflecting on their learning.
Science, Technology and Society
Meaningful learning occurs if students can relate their learningwith their daily experiences. Meaningful learning occurs in
learning approaches such as contextual learning and Science,Technology and Society (STS).
Learning themes and learning objectives that carry elements ofSTS are incorporated into the curriculum. STS approachsuggests that science learning takes place through investigationand discussion based on science and technology issues in
society. In the STS approach, knowledge in science andtechnology is to be learned with the application of the principlesof science and technology and their impact on society.
Contextual Learning
Contextual learning is an approach that associates learning withdaily experiences of students. In this way, students are able toappreciate the relevance of science learning to their lives. Incontextual learning, students learn through investigations as inthe inquiry-discovery approach.
Mastery Learning
Mastery learning is an approach that ensures all students areable to acquire and master the intended learning objectives. Thisapproach is based on the principle that students are able to learnif they are given adequate opportunities. Students should beallowed to learn at their own pace, with the incorporation ofremedial and enrichment activities as part of the teaching-learning process.
Teaching and Learning Methods
Teaching and learning approaches can be implemented throughvarious methods such as experiments, discussions, simulations,projects, and visits. In this curriculum, the teaching-learningmethods suggested are stated under the column “SuggestedLearning Activities.” However, teachers can modify thesuggested activities when the need arises.
8/14/2019 Curriculum Specification Biology Form 4
http://slidepdf.com/reader/full/curriculum-specification-biology-form-4 19/77
11
The use of a variety of teaching and learning methods canenhance students’ interest in science. Science lessons that arenot interesting will not motivate students to learn andsubsequently will affect their performances. The choiceof teaching methods should be based on the curriculum content,
students’ abilities, students’ repertoire of intelligences, and theavailability of resources and infrastructure. Besides playing therole of knowledge presenters and experts, teachers need to actas facilitators in the process of teaching and learning. Teachersneed to be aware of the multiple intelligences that exist amongstudents. Different teaching and learning activities should beplanned to cater for students with different learning styles andintelligences.
The following are brief descriptions of some teaching andlearning methods.
Experiment
An experiment is a method commonly used in science lessons.In experiments, students test hypotheses through investigationsto discover specific science concepts and principles. Conductingan experiment involves thinking skills, scientific skills, andmanipulative skills.
Usually, an experiment involves the following steps:
? Identifying a problem.
? Making a hypothesis.
? Planning the experiment- controlling variables.
- determining the equipment and materials needed.
- determining the procedure of the experiment and themethod of data collection and analysis.
? Conducting the experiment.
? Collecting data.
? Analysing data.
? Interpreting data.
? Making conclusions.
? Writing a report.
In the implementation of this curriculum, besides guiding studentsto do an experiment, where appropriate, teachers should providestudents with the opportunities to design their own experiments.This involves students drawing up plans as to how to conductexperiments, how to measure and analyse data, and how topresent the outcomes of their experiment.
Discussion
A discussion is an activity in which students exchange questionsand opinions based on valid reasons. Discussions can be
conducted before, during or after an activity. Teachers shouldplay the role of a facilitator and lead a discussion by askingquestions that stimulate thinking and getting students to expressthemselves.
Simulation
In simulation, an activity that resembles the actual situation iscarried out. Examples of simulation are role-play, games and theuse of models. In role-play, students play out a particular rolebased on certain pre-determined conditions. Games requireprocedures that need to be followed. Students play games in
order to learn a particular principle or to understand the processof decision-making. Models are used to represent objects oractual situations so that students can visualise the said objects orsituations and thus understand the concepts and principles to belearned.
8/14/2019 Curriculum Specification Biology Form 4

12
Project
A project is a learning activity that is generally undertaken by anindividual or a group of students to achieve a certain learningobjective. A project generally requires several lessons tocomplete. The outcome of the project either in the form of a
report, an artefact or in other forms needs to be presented to theteacher and other students. Project work promotes thedevelopment of problem-solving skills, time management skills,and independent learning.
Visits and Use of External Resources
The learning of science is not limited to activities carried out inthe school compound. Learning of science can be enhancedthrough the use of external resources such as zoos, museums,science centres, research institutes, mangrove swamps, andfactories. Visits to these places make the learning of science
more interesting, meaningful and effective. To optimise learningopportunities, visits need to be carefully planned. Students maybe involved in the planning process and specific educationaltasks should be assigned during the visit. No educational visit iscomplete without a post-visit discussion.
Use of Technology
Technology is a powerful tool that has great potential inenhancing the learning of science. Through the use oftechnology such as television, radio, video, computer, andInternet, the teaching and learning of science can be made more
interesting and effective.
Computer simulation and animation are effective tools for theteaching and learning of abstract or difficult science concepts.Computer simulation and animation can be presented throughcourseware or Web page. Application tools such, as wordprocessor, graphic presentation software and electronic
spreadsheet are valuable tools for the analysis and presentationof data.
The use of other tools such as data loggers and computerinterfacing in experiments and projects also enhance theeffectiveness of teaching and learning of science.
CONTENT ORGANISATION
The biology curriculum is organised around themes. Each themeconsists of various learning areas, each of which consists of anumber of learning objectives. A learning objective has one ormore learning outcomes.
Learning outcomes are written based on the hierarchy of thecognitive and affective domains. Levels in the cognitive domainare: knowledge, understanding, application, analysis, synthesisand evaluation. Levels in the affective domain are: to be awareof, to be in awe, to be appreciative, to be thankful, to love, topractise, and to internalise. Where possible, learning outcomesrelating to the affective domain are explicitly stated. Theinculcation of scientific attitudes and noble values should beintegrated into every learning activity. This ensures a morespontaneous and natural inculcation of attitudes and values.Learning areas in the psychomotor domain are implicit in thelearning activities.
Learning outcomes are written in the form of measurablebehavioural terms. In general, the learning outcomes for aparticular learning objective are organised in order of complexity.However, in the process of teaching and learning, learningactivities should be planned in a holistic and integrated mannerthat enables the achievement of multiple learning outcomesaccording to needs and context. Teachers should avoid

13
employing a teaching strategy that tries to achieve each learningoutcome separately according to the order stated in thecurriculum specifications.
The Suggested Learning Activities provide information on thescope and dimension of learning outcomes. The learningactivities stated under the column Suggested Learning Activitiesare given with the intention of providing some guidance as tohow learning outcomes can be achieved. A suggested activitymay cover one or more learning outcomes. At the same time,more than one activity may be suggested for a particularlearning outcome. Teachers may modify the suggested activityto suit the ability and style of learning of their students. Teachersare encouraged to design other innovative and effective learningactivities to enhance the learning of biology.
