ข้อกำหนดเครื่องคิดเลข
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
วัตถุประสงค์: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
ใช้เมื่อใด: Checking solutions, sketching, or solving where an analytic method is hard.
ขั้นตอน
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
ใช้เมื่อใด: Iterative or implicit equations, or to confirm an algebraic solution.
ขั้นตอน
Use the equation/zero solver, entering the equation and a sensible starting estimate.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
ใช้เมื่อใด: Checking calculus answers, or where only a numerical value is needed.
ขั้นตอน
Use the GDC's numeric integral / derivative function with the limits or the point.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
ใช้เมื่อใด: Statistics questions and hypothesis tests.
ขั้นตอน
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
ข้อควรระวังในการสอบ: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 3Injury (Biomechanics)
Attributing Delayed Onset Muscle Soreness (DOMS) to the accumulation of lactic acid.
วิธีหลีกเลี่ยง: 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.
2highคะแนนที่เกี่ยวข้อง: 2Study Design and Research Methods
Treating standard deviation (SD) error bars as direct proof of accuracy or error, rather than data variability.
วิธีหลีกเลี่ยง: 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.
3mediumคะแนนที่เกี่ยวข้อง: 1Study Design and Research Methods
Failing to write down intermediate math steps, leading to zero credit when final values are calculated incorrectly.
วิธีหลีกเลี่ยง: 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.
4mediumคะแนนที่เกี่ยวข้อง: 2Generating movement in the body (Biomechanics)
Conflating the functions of ligaments and tendons during joint movement explanations.
วิธีหลีกเลี่ยง: Consistently define ligaments as connecting bone to bone (to stabilize joints) and tendons as connecting muscle to bone (to transmit force and generate movement).
5highคะแนนที่เกี่ยวข้อง: 2Generating movement in the body (Biomechanics)
Using colloquial or abbreviated muscle names like 'pecs', 'delts', or 'hamstrings'.
วิธีหลีกเลี่ยง: Use the full anatomical terms: pectoralis major, deltoid, rectus femoris, and biceps femoris.
6mediumคะแนนที่เกี่ยวข้อง: 1Response (Exercise physiology and nutrition of the human body)
Omitting the word 'maximal' when describing training-induced changes in stroke volume or cardiac output.
วิธีหลีกเลี่ยง: Ensure you specify that while submaximal heart rate may decrease with training, stroke volume increases at rest and cardiac output increases during maximal exercise.
7mediumคะแนนที่เกี่ยวข้อง: 2Forces, motion and movement (Biomechanics)
Drawing force arrows that do not originate from the correct point of contact or center of mass.
วิธีหลีกเลี่ยง: 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.
