Course Outline

Aims

Through studying any of Biology, students should become aware of how scientists work and communicate with each other.
While the “scientific method” may take on a wide variety of forms, it has an emphasis on a practical approach through
experimental work. It is in this context that all the Diploma
Programme

Biology course should aim to:


1. provide opportunities for scientific study and creativity within a global context that will stimulate and

challenge students


2. provide a body of knowledge, methods and techniques that characterize science and technology


3. enable students to apply and use a body of knowledge, methods and techniques that characterize

science and technology


4. develop an ability to analyse, evaluate and synthesize scientific information


5. engender an awareness of the need for, and the value of, effective collaboration and communication

during scientific activities


6. develop experimental and investigative scientific skills


7. develop and apply the students’ information and communication technology skills in the study of science


8. raise awareness of the moral, ethical, social, economic and environmental implications of using science

and technology


9. develop an appreciation of the possibilities and limitations associated with science and scientists


10. encourage an understanding of the relationships between scientific disciplines and the overarching

nature of the scientific method.

There are 3 levels of Understanding
demonstrated in this course:


Objective 1


Define Give the precise meaning of a word, phrase or
physical quantity.


Draw Represent by means of pencil lines.


Label Add labels to a diagram.


List Give a sequence of names or other brief answers with
no explanation.


Measure Find a value for a quantity.


State Give a specific name, value or other brief answer
without explanation or calculation
.


Objective 2


Annotate Add brief notes to a diagram or graph.


Apply Use an idea, equation, principle, theory or law in a
new situation.


Calculate Find a numerical answer showing the relevant
stages in the working (unless instructed not to do so).


Describe Give a detailed account.


Distinguish Give the differences between two or more
different items.


Estimate Find an approximate value for an unknown
quantity.


Identify Find an answer from a given number of
possibilities.


Outline Give a brief account or summary.

Objective 3


Analyse Interpret data to reach conclusions.


Comment Give a judgment based on a given statement or
result of a calculation.


Compare Give an account of similarities and differences
between two (or more) items, referring


to both (all) of them throughout.


Construct Represent or develop in graphical form.


Deduce Reach a conclusion from the information given.


Derive Manipulate a mathematical relationship(s) to give a
new equation or relationship.


Design Produce a plan, simulation or model.


Determine Find the only possible answer.


Discuss Give an account including, where possible, a range
of arguments for and against the


relative importance of various factors, or comparisons of
alternative hypotheses.


Evaluate Assess the implications and limitations.


Explain Give a detailed account of causes, reasons or
mechanisms.


Predict Give an expected result.


Show Give the steps in a calculation or derivation.


Sketch


Represent by means of a graph showing a line and
labelled

but
unscaled

axes but with


important features (for example, intercept) clearly
indicated.


Solve Obtain an answer using algebraic and/or numerical
methods.


Suggest Propose a hypothesis or other possible answer.
