電卓の規定
A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.
AO1: Demonstrate knowledge and understanding of psychological ideas, processes and procedures. (35%)
AO2: Apply knowledge and understanding of psychological ideas, processes and procedures. (35%)
AO3: Analyze and evaluate psychological ideas, processes and procedures. (30%)

電卓プログラム
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
目的: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使う場面: Solving or sketching a function when you want to find where its graph crosses or turns.
手順
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
目的: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使う場面: Any data-handling, statistics, or required-practical analysis question.
手順
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
目的: Keep full-precision intermediate values to avoid rounding errors.
使う場面: Multi-step calculations where premature rounding loses the final accuracy mark.
手順
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
目的: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使う場面: As a check only, after solving by hand.
手順
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
よくあるミス
1high影響する配点: 2Scenario-based Applications (AO2)
Failing to link justifications directly back to the specific characters or individuals named in the scenario questions.
回避方法: Always mention the character's name explicitly and describe their specific action or situation alongside the psychological theory.
2high影響する配点: 3Extended Essays (AO3)
Using generic evaluative terms in essays, such as 'this lacks ecological validity' or 'this is reliable', without providing any specific context.
回避方法: Explain the exact details of why the setting or task was artificial, or what standardized procedure makes it replicable.
3medium影響する配点: 1Research methods
Leaving mathematical ratios in Paper 2 unsimplified or failing to round decimals properly.
回避方法: Always simplify ratios to their lowest terms using common factors (e.g. 14:25 instead of 56:100) and perform rounding at the final step.
4medium影響する配点: 4Synoptic Essays
Writing two completely isolated mini-essays in Paper 1's 9-mark synoptic assessment (Q23) instead of synthesizing the two areas.
回避方法: Find intersections between the two psychological areas and write paragraphs that compare or link both theories directly to the scenario.
5medium影響する配点: 2Criminal psychology
Confusing positive punishment with negative reinforcement in learning theory explanations.
回避方法: Remember that positive punishment ADDS an unpleasant stimulus to stop behavior, while negative reinforcement REMOVES an unpleasant stimulus to encourage behavior.
6high影響する配点: 1Research methods
Omitting the complete label and measurement units of the y-axis when drawing bar charts in Paper 2.
回避方法: Always use a ruler and pencil, label both axes fully, and include specific scale units in parentheses, such as '(out of 10)'.
