電卓の規定

A graphic display calculator (GDC) from the IB-approved list is required for most Mathematics and Sciences papers and must be set to examination mode. Note that some papers do not permit a calculator (for example Mathematics Paper 1 and the multiple-choice Sciences Paper 1).

  • AO1: Knowledge and comprehension
  • AO2: Application and analysis
  • AO3: Synthesis and evaluation

電卓プログラム

Graph: zeros, intersections & turning points

Graphical calculator / GDC (exam mode)

目的: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.

使う場面: Checking solutions, sketching, or solving where an analytic method is hard.

手順
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.

試験での注意: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Numerical equation solver

Graphical calculator / GDC (exam mode)

目的: Solve an equation or find a variable numerically when an algebraic route is long or implicit.

使う場面: Iterative or implicit equations, or to confirm an algebraic solution.

手順
Use the equation/zero solver, entering the equation and a sensible starting estimate.

試験での注意: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Numerical integration & differentiation

Graphical calculator / GDC (exam mode)

目的: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.

使う場面: Checking calculus answers, or where only a numerical value is needed.

手順
Use the GDC's numeric integral / derivative function with the limits or the point.

試験での注意: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Statistics & probability distributions

Graphical calculator / GDC (exam mode)

目的: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.

使う場面: Statistics questions and hypothesis tests.

手順
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).

試験での注意: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

よくあるミス

  1. 1high影響する配点: 4Biological approach to understanding behaviour (Core)

    Describing multiple research studies or techniques in Section A SAQs, which wastes precious exam time.

    回避方法: Present and detail exactly one high-quality, relevant study. Examiners will only grade the first study described.
  2. 2high影響する配点: 5Sociocultural approach to understanding behaviour (Core)

    Confusing enculturation (learning native cultural schemas) with acculturation (cultural change from foreign contact).

    回避方法: Explicitly define enculturation as internalizing one's primary native culture and acculturation as adjusting to a new culture.
  3. 3high影響する配点: 3Approaches to researching behaviour (Core)

    Providing a one-sided evaluation (strengths only or limitations only) in ERQs.

    回避方法: Ensure every evaluation essay presents a balanced review of both strengths and limitations to avoid a 3-mark cap on Criterion D.
  4. 4medium影響する配点: 4Biological approach to understanding behaviour (Core)

    Treating brain-imaging techniques (like MRI and fMRI) as research methods.

    回避方法: Classify fMRI/MRI as technology tools utilized within a research method like an experiment or case study.
  5. 5high影響する配点: 6Abnormal psychology (Options)

    Writing sequential descriptive essays for 'Contrast' questions in Paper 2 rather than directly comparing factors throughout.

    回避方法: Structure contrast essays comparatively from the start, highlighting explicit similarities and differences throughout the response.
  6. 6medium影響する配点: 4Biological approach to understanding behaviour (Core)

    Failing to explicitly link animal research findings back to human neurobiology and behavior.

    回避方法: When utilizing animal models, actively write a conceptual bridge detailing the specific evolutionary or physiological links to human behavior.
