計算機規定
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: AO1: Demonstrate knowledge and understanding
AO2: AO2: Apply knowledge and understanding
AO3: AO3: Analyze, evaluate and synthesize scientific information
根據歷屆試題與評分準則整理(2023–2025)。
計算機程式
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使用時機: Checking solutions, sketching, or solving where an analytic method is hard.
步驟
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考試提示: 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)
用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使用時機: Iterative or implicit equations, or to confirm an algebraic solution.
步驟
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考試提示: 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)
用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使用時機: Checking calculus answers, or where only a numerical value is needed.
步驟
Use the GDC's numeric integral / derivative function with the limits or the point.
考試提示: 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)
用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使用時機: Statistics questions and hypothesis tests.
步驟
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考試提示: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
常見錯誤
1high涉及分數: 3Injury (Biomechanics)
Attributing Delayed Onset Muscle Soreness (DOMS) to the accumulation of lactic acid.
如何避免: Explain that DOMS is caused by microdamage/micro-tears in eccentric muscle fibers, which triggers an inflammatory response. Clarify that lactic acid is cleared from the blood shortly after exercise and is not the cause.
2high涉及分數: 2Study Design and Research Methods
Treating standard deviation (SD) error bars as direct proof of accuracy or error, rather than data variability.
如何避免: Define standard deviation as the dispersion of data points around the mean. When comparing means, state clearly that overlapping error bars indicate that the observed differences are not statistically significant.
3medium涉及分數: 1Study Design and Research Methods
Failing to write down intermediate math steps, leading to zero credit when final values are calculated incorrectly.
如何避免: Always show your full working (e.g. subtraction steps or fraction setup for percentage changes) so that method marks can be awarded even if a rounding error occurs.
4medium涉及分數: 2Generating movement in the body (Biomechanics)
Conflating the functions of ligaments and tendons during joint movement explanations.
如何避免: Consistently define ligaments as connecting bone to bone (to stabilize joints) and tendons as connecting muscle to bone (to transmit force and generate movement).
5high涉及分數: 2Generating movement in the body (Biomechanics)
Using colloquial or abbreviated muscle names like 'pecs', 'delts', or 'hamstrings'.
如何避免: Use the full anatomical terms: pectoralis major, deltoid, rectus femoris, and biceps femoris.
6medium涉及分數: 1Response (Exercise physiology and nutrition of the human body)
Omitting the word 'maximal' when describing training-induced changes in stroke volume or cardiac output.
如何避免: Ensure you specify that while submaximal heart rate may decrease with training, stroke volume increases at rest and cardiac output increases during maximal exercise.
7medium涉及分數: 2Forces, motion and movement (Biomechanics)
Drawing force arrows that do not originate from the correct point of contact or center of mass.
如何避免: Begin the tail of your force vector arrow exactly at the application point (e.g., foot-to-ground contact or the system's center of gravity) and include a clear directional arrowhead.
