📚 Cambridge IGCSE Science 2026 Exam Changes & Trends | 剑桥IGCSE科学2026年考试变化与趋势
From 2026, Cambridge IGCSE Science qualifications (Biology 0610, Chemistry 0620, Physics 0625 and Co-ordinated Sciences 0654) will undergo the most significant structural overhaul in over a decade. The tiered system that once split candidates into Core and Extended is being replaced by a single, unified assessment model designed to offer deeper challenge while keeping high-quality science accessible to all learners.
从2026年起，剑桥IGCSE科学科目（生物0610、化学0620、物理0625及综合科学0654）将经历十多年来最重大的结构性改革。过去将考生分为核心与拓展的分级体系将被统一的评估模型取代，旨在提供更深层次的挑战，同时让所有学习者都能接触高质量的科学内容。
1. Introduction to the 2026 Syllabus Update | 2026年大纲更新简介
The new syllabuses, first examined in June 2026, reflect Cambridge's drive to modernise science assessment. They aim to reduce barriers for entry while stretching capable candidates through tier-less papers, updated practical endorsements and more nuanced command words.
新大纲将于2026年6月首次考试，体现了剑桥推动科学评估现代化的决心。其目标是通过去层级化的试卷、更新的实践认证以及更加精确的指令词，既降低入门门槛，又充分挑战能力突出的考生。
Key drivers behind the change include international research into science literacy, teacher feedback on the old Core/Extended divide, and a desire to align more closely with real-world scientific problem-solving.
推动这一变化的关键因素包括国际科学素养研究、教师对旧有核心/拓展划分的反馈，以及希望评估更贴近现实世界科学问题解决的愿望。
2. Farewell to Core and Extended Tiers | 告别核心与拓展层级
One of the most talked-about changes is the removal of the Core and Extended tier option. Previously, schools chose between two difficulty levels per subject, which often dictated the maximum achievable grade (C for Core, A* for Extended). From 2026, every candidate sits the same set of papers.
最受热议的变化之一就是取消核心和拓展层级选项。此前，学校在每个科目上选择两种难度级别，这往往决定了学生能获得的最高等级（核心最高C，拓展最高A*）。从2026年起，所有考生参加同一套试卷。
This unified approach means grade boundaries will be determined by overall performance rather than by pre-selected tier. Every learner now has a clear route to the full A* grade, reducing the risk of tier-locked outcomes.
这种统一方案意味着等级分数线将由整体表现决定，而不再由预先选择的层级锁定。每位学习者现在都有通向A*等级的明确路径，降低了因层级限制导致成绩被锁定的风险。
3. Transformed Paper Structure: A Closer Look | 试卷结构转型：深入解读
Under the new model, each IGCSE science subject features three components. A typical structure for Biology, Chemistry and Physics is: Paper 1 Multiple Choice (40 marks, 45 minutes), Paper 2 Theory (80 marks, 1 hour 45 minutes), and either Paper 3 Practical Test (40 marks, 1 hour) or Paper 4 Alternative to Practical (40 marks, 1 hour). Co-ordinated Sciences follows a similar logic but with combined papers.
在新模式下，每个IGCSE科学科目包含三个组成部分。生物、化学和物理的典型结构为：试卷1选择题（40分、45分钟）、试卷2理论题（80分、1小时45分钟），以及试卷3实验操作考试（40分、1小时）或试卷4实验替代笔试（40分、1小时）。综合科学遵循类似的逻辑，但采用组合试卷。
The disappearance of separate Core Theory and Extended Theory papers is the headline. Instead, a single Theory paper is designed with progressive difficulty, embedding questions that range from recall to complex analysis.
最显著的变化是独立的核心理论卷和拓展理论卷不复存在。取而代之的是单一理论试卷，其难度呈渐进式设计，包含从基础识记到复杂分析的各类问题。
4. How Difficulty Is Differentiated Inside a Unified Paper | 统一试卷内部如何区分难度
You might wonder: 'If there is only one paper, how will it challenge everyone?' The answer lies in carefully layered questioning. Early sections feature straightforward multiple-choice and structured questions targeting knowledge and comprehension. Later sections introduce data interpretation, unfamiliar contexts and evaluate-style questions that demand higher-order thinking.
你可能会想：“如果只有一份试卷，如何挑战每个人？”答案在于精心分层的提问。早期部分包括直接的选择题和结构化问题，针对知识和理解力。后续部分则引入数据解释、陌生情境以及要求高阶思维的评估型问题。
This structure rewards consistent study while allowing strong performers to excel without a separate Extended paper. Students will see command words such as 'describe', 'explain', 'suggest' and 'evaluate' clearly signalling the cognitive demand at each step.
这种结构奖励持续学习，同时让表现优异的学生无需单独拓展试卷也能脱颖而出。学生们会看到诸如“描述”、“解释”、“建议”和“评价”等指令词，清晰地标示每一步的认知要求。
5. Practical Skills Move to the Forefront | 实验技能走向前台
Practical work remains central, but the assessment has been refined. The new Practical Test (Paper 3) and the Alternative to Practical (Paper 4) retain a similar feel, yet the syllabus now places stronger emphasis on experimental design, error analysis and safe manipulation of apparatus. Simple recall of set practicals is no longer enough.
实验工作仍然是核心，但评估已被精炼。新的实验操作考试（试卷3）和实验替代笔试（试卷4）保留了相似的形式，然而大纲现在更加强调实验设计、误差分析以及安全操作仪器。仅仅背记规定实验已不足够。
Teachers are encouraged to build a portfolio of hands-on skill development throughout Year 10 and 11. The ability to plan an investigation, identify variables, plot graphs with lines of best fit and evaluate limitations is explicitly tested.
鼓励教师在十年级和十一年级全程建立动手技能发展档案。计划调查、识别变量、绘制带最佳拟合线的图表以及评估局限性等能力会被明确考查。
6. Command Words and Assessment Objective Shifts | 指令词与评估目标的转变
Assessment Objectives (AOs) have been redistributed. AO1 Knowledge with understanding, AO2 Handling information and problem-solving, and AO3 Experimental skills and investigations now carry slightly different weightings. AO2 and AO3 gain marginal prominence, reflecting the increased importance of application and practical insight.
评估目标（AO）已重新分配。AO1知识理解、AO2信息处理与问题解决以及AO3实验技能和调查，现在有着略微不同的权重。AO2和AO3的地位略有提升，反映出应用与实践洞察力的重要性增加。
Command words like 'calculate', 'determine', 'evaluate' and 'predict' appear more frequently. This signals that rote learning must give way to genuine understanding of scientific processes. Students should practise using formulas, interpreting graphs and drawing conclusions from data sets.
像“计算”、“测定”、“评价”和“预测”这样的指令词出现得更加频繁。这标志着机械记忆必须让位于对科学过程的真正理解。学生应练习使用公式、解读图表以及从数据集得出结论。
7. Curriculum Content: What Has Been Added or Removed? | 课程内容：增加了什么，删除了什么？
While the core concepts remain stable, some topics have been streamlined and a few new applications introduced. For example, in Biology, there is a greater focus on the impact of human activity on ecosystems and sustainable practices. Chemistry sees an expanded treatment of organic chemistry basics and green chemistry principles. Physics incorporates more modern energy resources and the principles of digital sensors.
虽然核心概念保持稳定，但部分主题被精简，并引入了一些新的应用。例如，在生物学中，更加关注人类活动对生态系统的影响以及可持续实践。化学对有机化学基础和绿色化学原则进行了扩展处理。物理纳入了更多现代能源资源和数字传感器原理。
Content has been reorganised into clearer learning sequences. Cross-references between topics help students see the bigger picture, supporting synoptic understanding that the new exams reward.
内容被重新组织成更清晰的学习序列。主题之间的交叉引用帮助学生看到更广阔的全貌，支持新考试所奖励的综合理解力。
8. Grading and Grade Descriptors: What to Expect | 评分与等级描述：应期待什么
With the removal of tiers, grade boundaries will apply to the entire cohort. Cambridge has published revised grade descriptors for A, C and E to reflect the unified model. Grade A candidates are expected to demonstrate thorough knowledge, accurate application and critical evaluation. A grade C still requires a solid grasp of the core material and competent practical skills.
随着层级的取消，等级分数线将适用于整个考生群体。剑桥已发布修订后的A、C和E等级描述，以反映统一模型。获得A等级的考生应展现全面的知识、准确的应用和批判性评价。C等级仍需扎实掌握核心材料且具备合格的实践技能。
Grade thresholds will be determined statistically after each session, but teachers can anticipate a similar distribution of top grades. However, the new format may initially produce slightly wider grade spreads as students adapt.
等级阈值将在每次考季后通过统计方式确定，但教师可以预期高分等级会有相似的分布。然而，新形式可能在初期产生略有扩大的等级分布，因为学生需要适应。
9. Implications for Year 10 Students Starting Now | 对现在入学的十年级学生意味着什么
Year 10 learners in a two-year programme will be the first cohort to sit the 2026 exams. This is both an opportunity and a responsibility. You will not have past papers identical to the new format, but Cambridge provides specimen papers and mark schemes that closely mirror the live assessments.
在两年的课程中学习的十年级学生将成为参加2026年考试的第一批考生。这既是机遇也是责任。你们将不会有与新格式完全相同的往年真题，但剑桥提供了与正式试卷高度相似的样卷和评分方案。
Your teachers will be embedding the new assessment style from day one. Pay close attention to how practical skills are integrated into every topic, and start practising the full range of command words early. There is no benefit in delaying deep processing.
你们的老师将从第一天起嵌入新的评估风格。密切关注实践技能如何融入每个主题，并尽早开始练习完整的指令词范围。延迟深度学习没有任何好处。
10. Study Strategies Adapted to the 2026 Paper Style | 适应2026年试卷风格的学习策略
Because the unified Theory paper mixes low-demand and high-demand items, effective revision requires a deliberate balance. Use spaced repetition for core facts and definitions, then move into targeted application tasks weekly. Timed practice with specimen questions is essential to build stamina for the 1-hour-45-minute Theory paper.
由于统一的理论试卷混合了低要求和高要求的题目，有效的复习需要刻意平衡。用间隔记忆法巩固核心事实和定义，然后每周进行针对性的应用任务。用样卷进行限时训练对于建立应对1小时45分钟理论卷的耐力至关重要。
Create summary sheets that link practical activities to theory, noting independent, dependent and control variables for each investigation. Practise plotting graphs with correct axes labels, units and scales. Explain your reasoning out loud or in writing to reinforce evaluative thinking.
制作将实践活动与理论联系起来的总结表，注明每次调查研究的自变量、因变量和控制变量。练习绘制带有正确坐标轴标签、单位和刻度的图表。大声或书写解释你的推理过程以强化评价性思维。
11. Predicted Trends and Future Directions | 预测趋势与未来方向
The 2026 changes signal Cambridge's long-term direction: science assessment is becoming more inclusive yet more intellectually demanding. The unified paper model may reduce anxiety about tier choice, but it raises the bar for baseline scientific literacy. Future syllabuses will likely integrate more climate science, data ethics and computational thinking.
2026年的变化预示着剑桥的长期方向：科学评估正变得更具包容性，同时也在智力上要求更高。统一试卷模式可能会减少对层级选择的焦虑，但提高了基础科学素养的门槛。未来的大纲可能会纳入更多气候科学、数据伦理和计算思维内容。
Digital examinations are on the horizon. Although 2026 paper-based exams remain, Cambridge is piloting on-screen assessments. Students who are comfortable reading graphs on screen and typing short answers may gain an edge when the transition happens further down the line.
数字化考试即将到来。虽然2026年仍为纸笔考试，但剑桥正在进行屏幕评估试点。习惯于在屏幕上阅读图表并用键盘输入简短答案的学生，在未来过渡时可能占据优势。
