📚 IGCSE Physics Syllabus Changes and Summer Exam Preparation Tips | IGCSE 物理考纲变化与夏季备考建议

With the 2025 IGCSE summer exams fast approaching, understanding the latest syllabus updates for Physics (0625 / 0972) is essential for every candidate. The Cambridge 2023–2025 syllabus introduced several key changes that will continue to be examined this summer, including a brand-new topic and a stronger focus on practical skills. This article breaks down the most important syllabus changes and provides a clear set of revision strategies to help you maximise your performance in the upcoming exams.

随着 2025 年 IGCSE 夏季大考临近，了解物理学科 (0625 / 0972) 的最新考纲变化对每一位考生都至关重要。剑桥 2023–2025 考纲引入了几项关键变化，包括一个全新主题以及对实验技能的更高要求，这些内容在今年夏季考试中仍将沿用。本文将详细解析最重要的考纲变化，并提供一套清晰的复习策略，帮助你在即将到来的考试中发挥出最佳水平。

1. Introduction to the 2023–2025 Syllabus | 2023–2025 考纲简介

Cambridge Assessment International Education updated the IGCSE Physics syllabus for examination from 2023 onwards. The current syllabus (available as 0625 for international candidates and 0972 for UK schools) will be examined in the June 2025 series without further modification. While the overall structure remains familiar, the revisions aim to reflect modern physics education, with a greater emphasis on scientific investigation and contemporary topics.

剑桥大学国际考评部对 IGCSE 物理考纲进行了更新，自 2023 年起开始实施。现行考纲（国际考生使用代码 0625，英国学校使用 0972）将在 2025 年夏季考试中继续沿用，不再做进一步修改。尽管整体框架仍为考生所熟悉，但此次修订旨在反映现代物理教育的需求，更加强调科学探究以及具有时代性的主题。

Students and teachers must download the official 2023–2025 syllabus document from the Cambridge website and use it as a checklist throughout revision. The syllabus clearly defines what is required for Core and Extended candidates, and highlights the practical skills to be assessed. Being syllabus-led is the single most effective way to avoid wasting time on outdated or irrelevant material.

学生和教师必须从剑桥官方网站下载 2023–2025 考纲文件，并将其作为复习清单。考纲明确规定了核心和扩展考生各自需要掌握的内容，并标注了将被评估的实验技能。以考纲为纲是避免在过时或无关内容上浪费时间的最有效方法。

2. New Topic: Space Physics | 新增主题：空间物理

The most striking addition to the syllabus is the ‘Space physics’ topic (section 6.2). This is examined in both Paper 1/2 and Paper 3/4 for Extended candidates, and introduces content that was previously absent from IGCSE Physics. The topic covers the Earth, the Solar System, the life cycle of stars, and our place in the Universe.

考纲中最引人注目的新增内容是“空间物理”主题（第 6.2 节）。对于扩展考生而言，这部分内容既会在选择题卷（Paper 1/2）中考查，也会在理论卷（Paper 3/4）中出现，它引入了此前 IGCSE 物理中未曾涉及的知识。该主题涵盖地球、太阳系、恒星的生命周期以及我们在宇宙中的位置。

You must be able to describe the orbits of planets, moons, and artificial satellites; explain the formation of a star from a nebula; outline the stages of a star’s life cycle, including the main sequence, red giant, white dwarf, and supernova leading to neutron stars or black holes; and discuss evidence for the Big Bang theory, such as the red-shift of light from distant galaxies and cosmic microwave background radiation. These concepts are now regular features in past papers since 2023.

你必须能够描述行星、卫星和人造卫星的轨道；解释恒星如何由星云形成；概述恒星生命周期的各个阶段，包括主序星、红巨星、白矮星，以及超新星爆发后形成的中子星或黑洞；并且讨论大爆炸理论的证据，例如来自遥远星系光的红移和宇宙微波背景辐射。自 2023 年以来，这些概念已经成为真题中的常客。

3. Content Reorganized and Removed Topics | 内容重组与删减

Besides adding Space physics, Cambridge reorganized several existing topics to improve coherence. For example, the sections on energy resources and thermal physics have been restructured, and radioactivity now sits more naturally within the nuclear physics chapter. Some older applications, such as the detailed operation of a cathode-ray oscilloscope, have been removed or simplified, making room for more contemporary contexts like digital electronics and renewable energy systems.

除了新增空间物理，剑桥还对若干已有主题进行了重组以增强条理性。例如，能源资源和热物理部分的结构得到了调整，放射性内容现在更自然地归属于核物理章节。一些较老的应用，例如阴极射线示波器的详细操作，已被删除或简化，为数字电子学和可再生能源系统等更具时代性的内容腾出了空间。

It is important to check the current syllabus against older notes. Several learning objectives that used to be Core requirements have shifted to the Supplement, and vice versa. For instance, calculations involving specific heat capacity and latent heat are now clearly assigned to Extended candidates. Relying on pre-2023 textbooks without cross-referencing the syllabus could mean you study topics that are no longer required or miss those that now carry greater weight.

务必用现行考纲对照你过去的笔记。一些曾经属于核心要求的教学目标已移至扩展部分，反之亦然。例如，涉及比热容和潜热的计算现在明确划归扩展考生。若只依赖 2023 年之前的教材而不对照考纲，你可能会学习已不再要求的内容，或者遗漏如今权重更高的知识点。

4. Emphasis on Scientific Inquiry and Practical Skills | 重视科学探究与实验技能

The 2023–2025 syllabus places a stronger, more explicit emphasis on practical skills. Assessment Objective 3 (AO3) – Experimental skills and investigations – accounts for 20% of the total marks, and the syllabus now includes a detailed list of practical skills that students are expected to develop. These include planning investigations, taking accurate measurements, handling data, drawing graphs, and evaluating sources of error.

2023–2025 考纲对实验技能给予了更为明确和突出的强调。评估目标 3（AO3）——实验技能与探究——占总分的 20%，考纲现在包含了一份详细清单，列出学生应当发展的实验技能。这些技能包括设计探究方案、精确测量、处理数据、绘制图表以及评估误差来源。

Even if you are sitting Paper 6 (Alternative to Practical) rather than Paper 5 (Practical Test), you must be thoroughly familiar with common apparatus, experimental techniques, and data analysis. Questions often ask you to suggest improvements to experimental setups, identify anomalous results, or calculate a gradient from a line of best fit. Simply memorising theory is no longer sufficient – you must think like a working scientist.

即使你参加的是实验替代试卷（Paper 6）而非动手操作试卷（Paper 5），你也必须彻底熟悉常见仪器、实验技术和数据分析方法。考题经常要求你提出实验装置的改进建议、识别异常数据，或者根据最佳拟合线计算斜率。仅仅背诵理论已不足以应对，你必须像一位在行的科学家那样思考。

5. Changes in Assessment Objectives and Weighting | 评估目标与权重变化

While the names of the three Assessment Objectives remain the same, their weightings have been fine-tuned to reflect a greater focus on applying knowledge to unfamiliar contexts. AO1 (Knowledge with understanding) now accounts for about 40%, AO2 (Handling information and problem solving) for another 40%, and AO3 for 20%. In the Extended papers, this means that recall questions are balanced by more demanding application and analysis tasks.

虽然三个评估目标的名称未变，但其权重经过了微调，以体现对在不熟悉情境中应用知识能力的更多重视。AO1（知识与理解）现在约占 40%，AO2（信息处理与问题解决）同样占 40%，AO3 占 20%。在扩展试卷中，这意味着回忆性题目会被更具挑战性的应用和分析类任务所平衡。

Teachers have observed that recent papers feature longer stem questions that provide a real-world context, such as the physics of a car braking system or the energy transfers in a wind turbine. To succeed, you must practise reading contextualised problems and linking them to the core physical principles you have learned. Pure rote learning will not prepare you for the manner in which concepts are now tested.

教师们观察到，近年试卷出现了更长的题干，并提供真实世界的背景情境，例如汽车制动系统的物理原理或风力涡轮机中的能量转换。要取得成功，你必须练习阅读情境化的问题，并将其与你所学过的核心物理原理联系起来。单纯的死记硬背无法让你应对如今概念被考查的方式。

6. Paper Structure and What to Expect in Summer Exams | 试卷结构与夏季考试预期

The summer 2025 examination will follow the standard structure established in 2023. Candidates who have studied the Core syllabus take Paper 1 and Paper 3, plus one practical component (Paper 5 or Paper 6). Extended candidates take Paper 2 and Paper 4, plus a practical paper. The table below summarises the papers:

2025 年夏季考试将遵循 2023 年确立的标准结构。学习核心大纲的考生参加 Paper 1 和 Paper 3，外加一个实验部分（Paper 5 或 Paper 6）。扩展考生则参加 Paper 2 和 Paper 4，外加一份实验试卷。下表总结了各试卷概况：
