1. Overview of 2026 Exam Changes | 2026年考试变化概览
The Cambridge Lower Secondary Checkpoint Science examination for Physics is expected to introduce modifications in question style and content emphasis from 2026. While the core topics remain, the weighting of assessment objectives will shift to reward critical thinking and experimental design. The exam will continue to feature both multiple-choice and structured questions but with more data interpretation tasks.
从2026年起，剑桥初中Checkpoint科学物理考试预计将在问题风格和内容重点上做出调整。虽然核心主题保持不变，但评估目标的权重将向批判性思维和实验设计倾斜。考试仍将包含选择题和结构化问题，但会增加更多的数据解读任务。
One notable trend is the integration of physics concepts with real-life scenarios, such as explaining forces in sports or energy transfers in household appliances. Students will need to apply their knowledge rather than just recall facts. Additionally, cross-topic synthesis questions will become more frequent, testing learners' ability to link ideas from different areas of physics.
一个显著的趋势是将物理概念与生活场景相结合，比如解释体育中的力或家用电器中的能量转移。学生需要运用知识，而不仅仅是复述事实。此外，跨主题综合题将更加常见，考察学生联系物理不同领域思想的能力。
2. Updated Curriculum Framework | 更新课程框架
The CAIE Lower Secondary Science framework (0893), revised for 2022–2024, remains the backbone of teaching. In 2026, minor tweaks are likely to emphasise the 'Science in Context' strand. Topics such as Forces and Motion, Energy, Waves, Electricity, and Magnetism remain core, but teachers will be encouraged to link them to sustainability and technology.
CAIE初中科学课程框架（0893）于2022–2024年修订，至今仍是教学的基础。到2026年，可能会有微调，以突出“情境中的科学”这一主线。力与运动、能量、波、电学和磁学等主题仍是核心，但鼓励教师将它们与可持续发展和科技联系起来。
The learning objectives will increasingly require students to plan simple investigations, identify variables, and evaluate evidence. Physics will see a greater push towards quantitative analysis, with more calculations involving speed, density, and moments. Updated teaching resources will likely provide more exemplar materials featuring data-logging and digital simulations.
学习目标将越来越多地要求学生设计简单的探究活动、识别变量并评估证据。物理学科将更加强调定量分析，涉及速度、密度和力矩等更多的计算。更新的教学资源可能会提供更多包含数据记录和数字模拟的范例材料。
3. Assessment Structure & Weighting | 评估结构与权重
The Checkpoint Science test consists of two papers, each contributing 50 marks. Physics content is evenly distributed across both papers, typically accounting for about one-third of the marks. The 2026 examination may adjust the balance between AO1 (Knowledge with understanding), AO2 (Handling information and problem-solving), and AO3 (Experimental skills and investigations). Current estimates suggest a shift from 40:40:20 to 35:45:20, rewarding application more heavily.
Checkpoint科学测试由两份试卷组成，每份占50分。物理内容均匀分布在两份试卷中，通常约占总分的三分之一。2026年的考试可能会调整AO1（知识与理解）、AO2（信息处理与问题解决）和AO3（实验技能与探究）之间的平衡。目前估计，权重将从40:40:20变为35:45:20，更加重视应用能力。
| Assessment Objective | Pre-2026 Weighting | 2026 Expected Weighting |
|---|---|---|
| AO1 Knowledge with understanding | 40% | 35% |
| AO2 Handling information and problem-solving | 40% | 45% |
| AO3 Experimental skills and investigations | 20% | 20% |
This subtle change means students must practise applying physics principles to unfamiliar problems. Command words such as 'explain', 'suggest', and 'calculate' will appear more often, demanding clear reasoning and step-by-step working. Paper 2, in particular, may include extended response items that assess scientific communication.
这一微妙变化意味着学生必须练习将物理原理应用于陌生问题。指令词如“解释”、“建议”和“计算”将更频繁地出现，要求清晰的推理和分步解答。特别是试卷2，可能会包含评估科学交流能力的拓展回答题。
4. Emphasis on Practical Skills (AO3) | 实验技能（AO3）的强调
Practical-based questions will now require students to describe not only what they observe but also why certain procedures are adopted. For instance, questions on measuring the speed of a moving object might ask for the identification of control variables and suggestions to improve accuracy. Experiments on simple pendulums or friction ramps will test the ability to design fair tests.
基于实验的问题现在要求学生不仅要描述观察到的现象，还要解释为什么采用某些步骤。例如，测量运动物体速度的问题可能会要求识别控制变量并提出提高准确度的建议。单摆或摩擦斜面实验将考验设计公平测试的能力。
Lab skills such as reading a stopwatch, using a ruler to measure distance, and recording data in a table will be directly assessed. Students must be familiar with common apparatus and safety precautions in physics experiments. Typical practical tasks include investigating how the length of a wire affects its resistance or exploring the reflection of light in plane mirrors.
使用秒表读数、用尺子测量距离、在表格中记录数据等实验技能将直接成为考点。学生必须熟悉物理实验中的常用仪器和安全注意事项。典型的实践任务包括探究导线长度如何影响其电阻，或探索平面镜中光的反射。
Expect to see questions that present a set of results and ask learners to identify anomalous points, calculate mean values, and draw conclusions. This shift aligns with the 'working scientifically' approach, nurturing the habits of a true scientist.
可预见到考题会提供一组结果，要求考生识别异常点、计算平均值并得出结论。这一转变符合“科学化工作”的方法，培养真正科学家的习惯。
5. Mathematical Skills in Physics | 物理中的数学技能
Mathematical requirements are becoming more explicit. Students are expected to use and rearrange formulas, convert units, and interpret graphs. Key equations for Year 8 include:
数学技能的要求变得更加明确。学生需要会使用和变换公式、进行单位换算以及解读图表。八年级的关键公式包括：
- average speed = total distance ÷ total time
- density = mass ÷ volume
- pressure = force ÷ area
- moment = force × perpendicular distance from pivot
Graph work will involve plotting line graphs of distance–time or extension–force, calculating gradients, and describing trends. Students should practise drawing lines of best fit and identifying anomalous points. Calculations may also involve converting between units such as cm to m, minutes to seconds, and g to kg.
图表作业将涉及绘制距离-时间或伸长量-力的线图，计算斜率，描述变化趋势。学生应练习绘制最佳拟合线并识别异常点。计算还可能涉及单位换算，如厘米换算为米、分钟换算为秒、克换算为千克。
average speed = total distance ÷ total time
This formula is central to numerous problems. In 2026, data might be presented in a table or graph, requiring students to extract information before substituting into the equation. Similarly, the density formula will be tested with irregular solids, linking to the practical skill of measuring volume by displacement.
该公式在众多问题中处于核心地位。到2026年，数据可能以表格或图表形式呈现，要求学生先提取信息再代入公式。同样，密度公式将与不规则固体结合测试，关联到通过排水法测量体积的实验技能。
6. Real-World Application & Context-Based Questions | 实际应用与情境题
Context-based questions will link physics to everyday life, such as explaining why a sharp knife cuts better (pressure), why astronauts seem weightless in space (gravity and free fall), or how ear defenders reduce sound (sound insulation). These questions test the ability to transfer understanding to unfamiliar situations.
情境题将物理与日常生活联系起来，例如解释为什么锋利的刀切东西更好（压强），为什么宇航员在太空中似乎失重（重力和自由落体），或者耳罩如何减小声音（隔音）。这些问题考察将理解迁移到陌生情境的能力。
Expect questions that combine multiple topics, e.g., a scenario involving a cyclist may ask about forces, motion, energy transformations, and even friction. Cross-topic integration will be more common in 2026. Another example is a solar-powered car: students might need to discuss energy changes from light to electrical to kinetic, as well as the forces opposing motion.
可预见到结合多个主题的问题，例如涉及骑自行车的情境可能会问及力、运动、能量转换甚至摩擦。跨主题综合题在2026年将更加常见。另一个例子是太阳能汽车：学生可能需要讨论从光能到电能再到动能的变化，以及阻碍运动的力。
In preparation, learners should read widely about how physics principles appear in technology and nature. This not only deepens understanding but also provides ready-to-use examples for extended answers.
在准备过程中，学生应广泛阅读物理原理如何在科技和自然中体现。这不仅加深理解，还为拓展回答提供了现成的例子。
7. Trends in Digital Assessment | 数字化评估趋势
Cambridge is gradually moving towards on-screen assessments. While Checkpoint Science is still primarily paper-based, pilot digital tests may be introduced in some regions by 2026. Digital questions could include interactive simulations, drag-and-drop ranking of forces, or video-based observations. Students should become comfortable with reading from screens and using digital tools for measurement.
剑桥正逐步转向屏上评估。虽然Checkpoint科学仍以纸笔为主，但到2026年，部分地区可能会试行数字化测试。数字题型可能包括交互式模拟、拖拽排序力的大小或基于视频的观察。学生应适应屏幕阅读和使用数字测量工具。
Even if the exam remains on paper, the style of questions is influenced by digital capabilities. For instance, data might be presented in dynamic tables or require interpretation of multi-step virtual experiments. Being familiar with simple data-logging software and online physics simulations (e.g., PhET) will give students an advantage.
即使考试仍以纸笔形式进行，题目风格也会受到数字化能力的影响。例如，数据可能以动态表格呈现，或要求解读多步骤的虚拟实验。熟悉简单的数据采集软件和在线物理模拟（如PhET）将使学生占据优势。
Teachers are encouraged to integrate ICT into physics lessons: using spreadsheets to plot graphs, analysing video clips of moving objects, or programming simple simulations. This approach mirrors the direction of assessment.
鼓励教师将信息技术融入物理课堂：使用电子表格绘制图表、分析运动物体视频片段，或编写简单的模拟程序。这种方法反映了评估的发展方向。
