IGCSE 生物主題：橡木標本板上放著不鏽鋼樣方（內有三件壓製植物標本）、三格標本木盒、盛土陶碟上長出的綠芽、放大鏡（鏡片放大下方葉片）、大片葉標本、摺疊黃銅放大鏡與兩枚乾豆莢。

Connect biological topics through mechanisms, then strengthen terminology, data and practical responses.

  • Connect cells, physiology, inheritance and ecology through recurring biological mechanisms
  • Replace keyword lists with precise explanations of location, sequence and consequence
  • Use values, calculations and limitations to judge what biological data can support
  • Control variation through suitable variables, sampling, repeats and evaluation

課程重點

Connect large amounts of content through biological mechanisms Organise cells, physiology, inheritance and ecology through recurring structure-function and system ideas.
Link scales
Move from molecules and cells to organisms and ecosystems.
Compare systematically
Use common criteria for organs, processes and adaptations.
Retrieve by mechanism
Use transport, energy, information and regulation to locate relevant knowledge.
 Write complete biological explanations Go beyond keywords by stating location, sequence, substances and consequences.
Follow the process
Explain what enters, changes, moves or responds at each stage.
Use precise terms
Distinguish similar structures and processes.
Answer the command
Separate describe, explain, compare and suggest.
 Use data as evidence, not decoration Describe patterns accurately, perform the required processing and judge what the data can support.
Reference values
State trends, ranges, comparisons and anomalies with data.
Calculate carefully
Handle magnification, percentage change, rate, ratio and probability.
Judge conclusions
Separate correlation, causation, reliability and limitations.
 Design fair and informative investigations Align variables, controls, sampling, measurement and analysis for either practical route.
Control biological variation
Choose controls, repeats, sample size and sampling method.
Plan data handling
Decide tables, graphs and calculations before collecting results.
Evaluate specifically
Link each limitation to an improvement and to the conclusion affected.
