電卓の規定
A silent scientific calculator may be used on papers where calculators are permitted (some papers are non-calculator). It must not be graphical or programmable and must hold no stored information.
AO1: Knowledge with understanding (30%)
AO2: Skills and analysis (52%)
AO3: Judgement and decision-making (18%)
過去問と採点基準にもとづいて作成（2023–2025）。
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 on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
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 on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
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 on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
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 on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
よくあるミス
1high影響する配点: 2Migration
Using circular definitions when explaining processes, such as defining forced migration as 'when people are forced to migrate'.
回避方法: Use distinct, precise terminology that avoids repeating the command words (e.g., define forced migration as 'the involuntary movement of people fleeing conflict, political instability, or environmental disasters').
2high影響する配点: 3Climate and natural vegetation
Reversing climate graph scales, plotting temperature on the rainfall axis or vice-versa.
回避方法: Always verify that temperature is represented by a line graph matching the left vertical axis (°C) and rainfall is represented by bar charts matching the right vertical axis (mm).
3high影響する配点: 4Geographical skills
Omitting graph axes completions and data plotting requirements on skills and fieldwork tasks.
回避方法: Perform a rigorous visual check on every page of Papers 2 and 4 to locate plotting tasks, incomplete bars, or missing key symbols.
4high影響する配点: 2Geographical skills
Presenting standalone raw statistics in comparison questions without utilizing comparative adjectives or connectives.
回避方法: Always pair statistics using comparative vocabulary (e.g., write 'the birth rate in Country A is 35 per 1000, whereas in Country B it is significantly lower at 12 per 1000').
5high影響する配点: 3Urban settlements
Drafting broad country-level case studies (e.g., citing only 'India' or 'Brazil') without place-specific regional, urban, or community scale facts.
回避方法: Ground your Level 3 case studies in local sub-districts, street-level initiatives, or exact project schemes (e.g., Dharavi slum in Mumbai, or the Curitiba urban transit plan).
6medium影響する配点: 2Environmental risks of economic development
Conflating global warming and the greenhouse effect with the chemical depletion of the ozone layer.
回避方法: Differentiate these completely: explain global warming as infrared radiation absorption by greenhouse gases, and ozone depletion as CFCs breaking down stratospheric O3 layers.
7medium影響する配点: 3Geographical skills
Confusing a bipolar environmental survey with a standard community questionnaire during fieldwork design.
回避方法: Recall that a bipolar survey scores physical parameters on a qualitative negative-to-positive numerical scale (-3 to +3), while a questionnaire records personal answers from respondents.
8high影響する配点: 2Geographical skills
Drawing segmented/divided bar graphs or pie charts starting each category's plot line from zero.
回避方法: Plot values cumulatively by adding each segment sequentially to the previous segment's end value (e.g., if segment A is 40% and B is 30%, B's dividing line must be drawn at 70%).
