官方報告整理

常見失分位

  • Drawing multiple, sketchy lines for curves of best fit instead of a single smooth curve.
  • Omitting the correct precision of decimal places (e.g. writing 41 instead of 41.0) when reading values from scales.
  • Incorrect rearrangement of simple equations like density or speed-time relationships.
  • Failing to convert time units (e.g. 4 h 15 min to 4.25 h, or minutes to seconds) before plugging into physics formula.

常見誤解

  • Believing that tap water is a pure substance rather than a solution of dissolved solids.
  • Believing that fertilisation in humans takes place in the uterus rather than the oviducts.
  • Confusing the functions of goblet cells and ciliated cells, thinking that goblet cells move the mucus.
  • Thinking that water vapour exits the stomata via active transpiration or evaporation rather than diffusion.

失分原因

  • Losing marks on ray diagrams because the line did not start exactly at position Y or didn't pass through the principal focus.
  • Inability to state the correct units for calculations, such as forgetting the unit for resistance (ohms/Ω) or pressure (Pa).
  • Providing vague answers like 'avoid contamination' instead of explaining why a clean glass rod prevents the transfer of enzymes.
  • Stating that the offspring of sexual reproduction are 'non-identical' without specifying that there are genetic differences.
