Study Notes

Science 3, 4, 5, and 6 Third Quarter Examinations

  • Table of Specifications (TOS): Documents outlining the distribution of test items across different skills and learning objectives. Used to ensure balanced assessments.

  • Competencies: Skills students are expected to demonstrate. These vary by grade level (3, 4, 5, and 6).

  • Domains: Categories of cognitive skills assessed, such as remembering, understanding, applying, analyzing, evaluating, and creating. The distribution of items across domains is specified in the TOS.

  • Item Numbers: Unique identifiers for each question or task on the test.

  • Total Number of Test Items: The overall count of questions/tasks for each subject.

  • Specific Competencies (Examples):

    • Participate in activities to discover and predict how rigid and soft objects change shape.
    • Measure distance and time to calculate speed.
    • Identify force as changing the shape of objects.
    • Use simple equipment to study motion and speed.
    • Investigate the properties of magnets.
    • Explore the effects of objects not in contact, such as magnets and light.
    • Understand the concept of energy in different forms (light, sound, heat).
    • Identify and observe energy sources in different environments (school, home, community).

  • Specific Grade Level Competencies (Examples - from Science 5):

    • Describe the motion of objects using distance/time relationships.
    • Understand why some materials are good conductors of heat/electricity.
    • Explain the properties of materials relating to light transmission.
    • Design experiments to learn how to make a bulb light.
    • Analyze how changing circuit components affects circuits.
    • Investigate factors affecting the strength of electromagnets.

  • The information is grade-specific with different competencies and skills being emphasized for each. For example, Science 3 focuses on position/relationships, and Science 5 is more complex involving circuits and electromagnetism.

  • Note the consistent pattern in the structure, with similar elements repeated for each grade level.
