SPM Biology PEKA Assessment Guide contains information about the objectives, characteristics and organization of SPM Biology PEKA. It also outline the assessment procedures to serve as guidelines for teachers to carry out the assessment in a coordinated manner. 2.0 OBJECTIVES OF SPM BIOLOGY PEKA The objectives in conducting SPM Biology PEKA is to enable the pupils to : * Master the Scientific Skills * * Science Process Skills Science Manipulative Skills Strengthen the knowledge and understanding of scientific theories and concepts. Inculcate the Scientific Attitudes and Noble Values 3.0 THE CHARACTERISTICS OF SPM BIOLOGY PEKA 3.1 Compatibility with the Curriculum Specification The assessment should be compatible with the knowledge, scientific skills, scientific attitudes and noble values to be developed in the teaching and learning process as specified in the SPM Biology Curriculum. 3.2 Pupil-centered All activities should be carried out by the pupils in a conducive environment and guided by the teacher’s teaching plan. The pupils should be assessed in accordance to their abilities and readiness. 3.3 Feasible and Systematic The format of assessment is designed to be practical and manageable. The assessment procedure should be systematic to enable teachers to administer the assessment efficiently. 9 Continuous Monitoring The 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.7 Valid and Reliable The validity of the assessment is determined by the scores that portray relevant information on the constructs assessed. 3. folio. 3.3 3. scrap book. check-lists and models as evidence of their ability and their level of performance. The reliability of the assessment refers to the consistency and accuracy of the scores obtained through the process of moderation and monitoring.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. Throughout the assessment period the pupils are encouraged to acquire knowledge and experience and also given opportunities to improve their work and their score. is achieved. It is ascertained by ensuring the constructs assessed are within the curriculum specification. project. . 3. 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.5 Variety of Instruments Pupils may use a variety of instruments such as practical report.6 Continuous and Formative Assessment The assessment is to be carried out from Form 4 to Form 5. The maximum score of each construct is 3. 9 5 . 4. The teachers are required to manage the evidence produced by the pupils. 7 3.4 1 .2 Grade A B C D . The maximum score for each construct is 9.6.0 THE ORGANIZATION OF SPM BIOLOGY PEKA 4. Total Score 8.1 Planning The assessment should be planned accordingly which includes aspects such as: 4.3 Scoring Scores are awarded based on the scoring scheme. The grade for each total score is shown below.2 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 Administration All evidence for assessment are collected and assessed by teachers responsible in the teaching and learning process of the subject.4 4. The three best scores for each construct are taken from the assignments assessed. 5. 5.3 Scientific Attitudes and Noble Values should be assessed simultaneously with other skills.5 4.4 Teachers assess and score the evidence presented by the pupil.4 Reporting The scores and grades are recorded in the Individual Score Form (ISF) and compiled into the Master Score Form (MSF) 4. 5.6 Pupils must submit a complete evidence.8 Pupils should be given adequate opportunity to master the required skills before the assessment is made. Pupils who have not mastered any assessed constructs are given the opportunity to repeat it in another assignment. 5.0 METHOD FOR ASSESSMENT 5. 5. Teachers can assess either one construct/skill or several constructs/skills of a small group of pupils or of the whole class. .1 5.7 Students must complete enough assignments to ensure that all the constructs have been assessed. 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 Moderation A mechanism to ensure that pupils of similar skill level of each construct are given similar scores.5 5. 5. All the information regarding the evidence are accessible to the pupils.2 SPM Biology PEKA is carried out as a part of teaching and learning process. 6 5. The highest score for each construct could be taken from either year. 6. 4 and 5 contain a list of the skills used as performance indicators.0 THE FRAMEWORK OF SPM BIOLOGY PEKA 6.Pusat Perkembangan Kurikulum.
