3.4 Open and Transparent
The pupils should be informed of the following aspects :
What are the constructs that will be assessed?
How will the construct be assessed?
When will the construct be assessed? Where will the construct be assessed?
3.5 Variety of Instruments
Pupils may use a variety of instruments such as practical report, folio, project,
scrap book, check-lists and models as evidence of their ability and their level of
performance.
3.6 Continuous and Formative AssessmentThe assessment is to be carried out from Form 4 to Form 5. Throughout the
assessment period the pupils are encouraged to acquire knowledge and
experience and also given opportunities to improve their work and their score.
3.7 Valid and Reliable
The validity of the assessment is determined by the scores that portray relevant
information on the constructs assessed. It is ascertained by ensuring the
constructs assessed are within the curriculum specification.
The reliability of the assessment refers to the consistency and accuracy of thescores obtained through the process of moderation and monitoring.
3.8 Positive Reports
The scores reported should show that an acquisition of skills that stimulates the
pupils to improve on their performance and achievement to a better level of
mastering skills, is achieved.
3.9 Continuous MonitoringThe assessment process SPM Biology PEKA has to be monitored and
supervised systematically from time to time to ensure that it is carried out in
accordance to its objectives and procedures.

4.1 Planning
The assessment should be planned accordingly which includes aspects such as:
- the pupils to be assessed- the time / duration to conduct the assessment
- the frequency of the assessment
- the personnel involved
- the type of instrument
- the scoring
- the grading
- the reporting
4.2 Administration
All evidence for assessment are collected and assessed by teachers responsible
in the teaching and learning process of the subject. The teachers are required to
manage the evidence produced by the pupils.
4.3 Scoring
Scores are awarded based on the scoring scheme.
The maximum score of each construct is 3.
The three best scores for each construct are taken from the assignmentsassessed.
The maximum score for each construct is 9.
The grade for each total score is shown below.

4.4 Reporting
The scores and grades are recorded in the Individual Score Form (ISF) and
compiled into the Master Score Form (MSF)
4.5 Moderation
A mechanism to ensure that pupils of similar skill level of each construct are
given similar scores. Moderation is an essential process to standardize and
monitor school based assessments in order to maintain the validity and reliability
of the assessment conducted by the teacher.
5.0 METHOD FOR ASSESSMENT
5.1 SPM Biology PEKA is carried out as a part of teaching and learning process.
5.2 Teachers can assess eit her one const ruct/skill or several
constructs/skills of a small group of pupils or of the whole class.
5.3 Scien ti fi c At ti tudes and Noble Values shou ld be assessed
simultaneously with other skills.
5.4 Teachers assess and score the evidence presented by the pupil. All
the information regarding the evidence are accessible to the pupils.
5.5 Pupils must submit a complete evidence.
5.6 Pupils who have not mastered any assessed constructs are given the
opportunity to repeat it in another assignment.
5.7 Students must complete enough assignments to ensure that all the
constructs have been assessed.
5.8 Pupils should be given adequate opportunity to master the required
skills before the assessment is made.

We assume that all the heat released from the food samplehas been transferred to the water. Since the specific heatcapacity of water = 4.2 J-1g oC-1.
Energy value = 4.2 (Jg-1 oC-1) x mass of water (g) xincrease in temperature (oC)
_______________________________
Mass of peanut(g) x 1000
Energy value of cashew nut = 4.2 x 20 x 620.72
= 7233 J g -1
= 7.233 kJ g -1
Energy value of groundnut = 4.2 x 20 x 440.54
= 6488 J g -1
= 6.844 kJ g -1
C4 P 1 C4 P 2 C4 P 3
Discussion : The higher the rise in temperature of water, the more theenergy value content in the food sample.
C4 P 4
The rise in temperature for cashew nut is higher thangroundnut. Therefore, the energy value for the cashew nutis higher than the groundnut.
Conclusion : The energy value of cashew nut is different from theenergy value of groundnut. Cashew nut has a higher
energy value than groundnut. The hypothesis is accepted.

Procedure : 11. A cashew nut is weighed and its weight record.12. 20ml of distilled water is poured into a boiling
tube.13. The boiling tube is clamped to a retort stand.
14. The temperature of the distilled water in the boilingtube is recorded.
15. The pointed end of a long pin is poked into acashew nut. The other end of the pin is poked intoa piece of plasticine.
16. The cashew nut is ignited by using a match stickand immediately placed under the boiling tube.
17. The flame from the cashew nut is allowed to heatup the water. The water is stirred gently by using athermometer to distribute the heat evenly. At thesame time the rise in temperature is observed.
18. The final temperature of the water is recorded in atable.
19. The energy value of the cashew nut is calculated.20. Steps 1 to 9 are repeated by using a groundnut.

We assume that all the heat released from the food samplehas been transferred to the water. Since the specific heatcapacity of water = 4.2 J-1g oC-1.
Energy value = 4.2 (Jg-1 oC-1) x mass of water (g) xincrease in temperature (oC)
_______________________________Mass of peanut(g) x 1000
Energy value of cashew nut = 4.2 x 20 x 620.72
= 7233
= 7.233
Energy value of groundnut = 4.2 x 20 x 440.54
= 6488
= 6.844
