For AS Biology students following the CCEA specification, the 2026 examination series marks a significant turning point. A revised specification, taught from September 2025, will be assessed for the first time, bringing new emphases, restructured papers and a sharper focus on practical and analytical skills. This article explores the key changes to the 2026 exams and the wider trends shaping CCEA Biology assessment, offering clear, bilingual guidance to help you navigate the shift with confidence.
对于学习 CCEA 课程的 AS 生物学生来说，2026 年考试系列标志着一个重要的转折点。从 2025 年 9 月开始教学的新大纲将迎来首次评估，带来了新的重点、重构的试卷以及对实验与分析技能更强烈的关注。本文探讨 2026 年考试的关键变化以及影响 CCEA 生物评估的宏观趋势，为你提供清晰的双语指引，帮助你从容应对这一转变。
1. Overview of the New AS Specification | 新 AS 大纲概览
The refreshed CCEA AS Biology course retains a three-unit structure but rebalances its content and skills demands. Unit AS 1 is titled Molecules and Cells, covering biochemistry, cell structure, membranes, enzymes and nucleic acids. Unit AS 2, Organisms and Biodiversity, deals with transport in plants and mammals, adaptation, classification and ecology. Unit AS 3 is Practical Skills in Biology, an externally assessed written paper that tests planning, data handling and evaluation of prescribed practicals. This structure mirrors the familiar pattern while embedding a more inquiry-driven approach.
更新后的 CCEA AS 生物课程保留了三个单元的结构，但重新平衡了内容与技能要求。第一单元 AS 1 题为 Molecules and Cells（分子与细胞），涵盖生物化学、细胞结构、膜、酶和核酸。第二单元 AS 2，Organisms and Biodiversity（生物体与生物多样性），涉及植物和哺乳动物的运输、适应、分类和生态学。第三单元 AS 3 是 Practical Skills in Biology（生物学实验技能），这是一份外部评估的笔试，考查实验计划、数据处理以及对规定实验的评价。这一结构延续了熟悉的模式，同时嵌入了更具探究导向的方法。
All three units are compulsory and contribute fixed percentages to the overall AS qualification. The weighting of each unit has been adjusted slightly compared with the outgoing specification, with Unit AS 3 now carrying additional significance. The aim is to place experimental reasoning at the heart of the subject, rather than treating it as an optional add-on.
三个单元都是必修单元，在 AS 总成绩中分别贡献固定比例。与旧大纲相比，每个单元的权重略微调整，其中 AS 3 单元现在具有更大的分量。其目的是将实验推理置于学科的核心，而不是作为可有可无的附加部分。
2. Content Revisions and Modernisation | 内容修订与现代化
CCEA has thoroughly updated the biology content to reflect advances in the life sciences and to reduce rote recall of excessive detail. New topics include an introduction to epigenetic regulation, a more explicit treatment of monoclonal antibodies in medical diagnostics, and the role of stem cells in developmental biology. Genetics sections now incorporate gene editing technologies such as CRISPR-Cas9, framed within ethical discussions that appear in examination questions.
CCEA 全面更新了生物学内容，以反映生命科学的进步，并减少了机械记忆过度细节的要求。新增主题包括表观遗传调控的简介、单克隆抗体在医学诊断中更明确的阐述，以及干细胞在发育生物学中的作用。遗传学部分如今融入了 CRISPR-Cas9 等基因编辑技术，这些内容将出现在考试题目中的伦理讨论框架内。
Ecology and biodiversity have been strengthened with climate-change case studies and the concept of ecosystem services. The specification encourages candidates to connect molecular processes to whole-organism responses, for example linking the light-independent reactions of photosynthesis to crop productivity under rising CO₂ levels. This contemporary lens makes the subject more relevant and rewards deep understanding.
生态学与生物多样性部分通过气候变化案例研究和生态系统服务的概念得到了加强。新大纲鼓励考生将分子过程与整个生物体的反应联系起来，例如将光合作用的暗反应与 CO₂ 浓度上升情况下的作物生产力联系起来。这种当代视角使学科更具相关性，并奖励深入的理解。
3. Rebalanced Assessment Objectives | 重新平衡的评估目标
The weighting of Assessment Objectives (AOs) in the 2026 exams has shifted noticeably. AO1 (Knowledge and understanding) now accounts for around 35% of the total marks, a reduction from the previous 40–45%. AO2 (Application of knowledge) rises to approximately 35%, and AO3 (Analysis, evaluation and synthesis) climbs to 30%. This rebalancing signals a clear move away from simple fact retrieval towards problem-solving and critical thinking.
2026 年考试中评估目标的权重已发生显著变化。AO1（知识与理解）现在约占总分的 35%，低于之前的 40–45%。AO2（知识应用）升至约 35%，AO3（分析、评价与综合）攀升至 30%。这种重新平衡清楚地表明从简单的事实回忆转向问题解决和批判性思维。
Questions are designed to target specific AOs, often blending two or three in a single item. For example, a data-response question on enzyme kinetics may require AO1 to recall the induced-fit model, AO2 to apply the model to a new graph, and AO3 to evaluate the limitations of the experimental design. Teachers and students must therefore embed AO practice into every topic from the start of the course.
题目旨在针对特定的评估目标，通常在一道题中混合两个或三个目标。例如，一道关于酶动力学的数据分析题可能需要 AO1 回忆诱导契合模型，AO2 将该模型应用到新的曲线图中，以及 AO3 评价实验设计的局限性。因此，教师和学生必须从课程伊始就将各 AO 的练习融入每个课题中。
4. Practical Skills Assessment Redesigned | 实验技能评估重新设计
Unit AS 3, the practical skills paper, is now a 1 hour 15 minute examination sat at the end of the AS year, worth 25% of the total AS marks. It is based on a list of prescribed practical activities that students carry out during the course. The paper assesses the ability to design investigations, identify variables, present results in tables and graphs, apply simple statistical tests, and draw evidence-based conclusions.
AS 3 单元——实验技能试卷，现在是 AS 学年结束时进行的 1 小时 15 分钟考试，占 AS 总分的 25%。考试基于学生在课程期间完成的一系列规定实验活动。试卷评估设计探究、识别变量、在表格和图表中呈现结果、应用简单统计检验以及得出有据可依的结论的能力。
A notable change is the greater emphasis on evaluating limitations and suggesting genuine improvements. Candidates can expect questions that ask ‘Explain why the method did not give accurate results’ or ‘Suggest two modifications that would increase validity’. The marking schemes demand precise, biological reasoning rather than generic comments about ‘human error’.
一个显著变化是更加强调评价局限性并提出真正的改进措施。考生可能会遇到这样的问题：“解释为什么该方法没有给出准确的结果”或“建议两项可以提高有效性的修改”。评分方案要求精确的生物学推理，而不是泛泛地评论“人为误差”。
Alongside the written paper, CCEA requires students to maintain a lab book or portfolio as evidence of practical competence. While this does not carry marks towards the AS grade, it forms the basis for the practical endorsement that appears on the certificate alongside the final grade. The endorsement does not affect university offers but is highly valued by admissions tutors, so consistent, careful recording is essential.
除笔试外，CCEA 要求学生维护实验记录本或作品集，作为实验能力的证据。虽然这不计入 AS 成绩，但它构成了实践认可的基础，该认可与最终成绩一同出现在证书上。实践认可不影响大学录取，但受到招生导师的高度重视，因此持续、细致的记录至关重要。
5. Mathematical and Data Handling Requirements | 数学与数据处理要求
Biology is becoming increasingly quantitative, and the 2026 specification reflects this trend. A minimum of 10% of the total AS marks must assess mathematical skills at a level equivalent to higher-tier GCSE Mathematics. This includes calculating percentages, ratios and rates, using standard form and significant figures, manipulating the magnification formula M = I/A, and plotting graphs with lines of best fit. In addition, students must be able to perform simple statistical tests such as the chi-squared (χ²) test and the t-test.
生物学正变得越来越定量化，2026 年的大纲反映了这一趋势。AS 总成绩中至少 10% 的分数必须评估相当于高等级 GCSE 数学水平的数学技能。这包括计算百分比、比率和速率，使用标准形式和有效数字，处理放大倍数公式 M = I/A，以及绘制带有最佳拟合线的图表。此外，学生必须能够进行简单的统计检验，例如卡方检验（χ²）和 t 检验。
Questions often embed data in tables or graphs that candidates have not seen before. The skill lies in extracting biological meaning from numerical patterns. For instance, a question on osmosis might present raw mass change data and ask students to calculate mean percentage change and explain why percentage change is preferred over absolute change. Such items test both mathematical competence and conceptual clarity.
考题经常将数据嵌入考生未见过的新表格或图表中。技巧在于从数字模式中提取生物学意义。例如，一道渗透作用的题目可能给出质量变化的原始数据，要求学生计算平均百分比变化，并解释为什么百分比变化优于绝对变化。这类题目既测试数学能力也考察概念的清晰程度。
6. The Shift Towards Synoptic Questions | 转向综合题
Synoptic assessment, which requires candidates to draw links across different topics, is no longer reserved for A2. The 2026 AS exams include structured questions that weave together concepts from multiple units. A typical question might start with the structure of starch (Unit AS 1), move to its digestion in the human gut (Unit AS 2), and finish by asking for adaptations of the ileum epithelium (Unit AS 2 again), thereby demanding fluid movement between topics.
综合性评估要求考生在不同主题之间建立联系，现在已不再专属于 A2 考试。2026 年的 AS 考试包含结构化问题，这些问题将多个单元的概念交织在一起。一道典型题目可能从淀粉的结构（AS 1）开始，转到它在人体肠道中的消化（AS 2），最后要求描述回肠上皮的适应性（同样是 AS 2），从而要求在不同主题之间流畅切换。
To prepare, students should regularly practise mapping key ideas on a single sheet, showing how cell signalling, enzyme activity and membrane transport intersect. Teachers are encouraged to spiral the curriculum, revisiting earlier content in later contexts. This approach not only aids exam performance but builds a genuinely integrated understanding of biology.
为了备考，学生应定期练习将关键观点绘制在一张纸上，展示细胞信号传导、酶活性和膜运输如何交叉。鼓励教师采用螺旋式课程设计，在后期情境中回顾早期内容。这种方法不仅有助于考试表现，还能构建真正融合的生物学理解。
7. Changes in Question Format and Command Words | 题目形式与指令词的变化
While multiple-choice items still appear occasionally, the majority of marks come from short-answer and extended-response questions. The new specification introduces more ‘unstructured’ extended writing, where the candidate must synthesise several strands of knowledge without sub-parts to guide them. Such questions demand planning and concise expression, rewarding quality over quantity.
虽然选择题仍然偶尔出现，但大部分分数来自简答题和拓展回答题。新大纲引入了更多“无结构”的拓展写作，考生必须综合多个知识线索，而无需小题引导。这类题目要求规划和简洁的表达，奖励质量而非数量。
Command words have been refined to signal the required response unambiguously. Common terms include ‘Name’ (simple recall), ‘Describe’ (step-by-step account), ‘Explain’ (give biological reasons), ‘Compare’ (similarities and differences), ‘Suggest’ (apply knowledge to a novel situation) and ‘Evaluate’ (weigh strengths and limitations). Examiners’ reports consistently show that higher marks go to answers that match the command word precisely, so regular drill with these terms pays off.
指令词已经过精炼，能明确提示所需的回答。常见术语包括“Name”（说出，简单回忆）、“Describe”（描述，逐步说明）、“Explain”（解释，给出生物学原因）、“Compare”（比较，异同点）、“Suggest”（建议，将知识应用于新情境）和“Evaluate”（评价，权衡优势和局限性）。考官报告始终表明，与指令词精确匹配的回答能获得更高分数，因此经常练习这些术语是值得的。
8. Grade Boundaries and Performance Standards | 分数线与表现标准
The first live examination of a new specification always brings a degree of uncertainty around grade boundaries. CCEA examiners will meet after the 2026 scripts are marked to set raw mark thresholds for grades A to E (and U). Because new specifications often produce slightly lower raw marks initially, boundaries tend to be more generous than in the final years of an outgoing specification.
新大纲的首次实考总是会给分数线带来一定程度的不确定性。在 2026 年试卷批改完毕后，CCEA 考官将开会设定 A 到 E（及 U）等级的原始分数门槛。由于新大纲在初期通常会产生稍低的原始分数，分数线往往比旧大纲最后几年更为宽松。
However, this does not mean the exam is easier. It reflects the fact that both students and teachers are adjusting to new question styles and content emphases. The key determinant of a student’s grade will be how well they demonstrate the assessment objectives. Consistent performance across all three units is vital; a weak Unit AS 3 score can pull down the overall grade significantly.
但这并不意味着考试更容易。它反映了学生和教师都在适应新的题型和内容重点。决定学生等级的关键因素是他们展示评估目标的程度。三个单元的稳定表现至关重要；AS 3 单元得分低会明显拉低总成绩。
9. Implications for Teaching and Learning | 对教学的影响
The 2026 changes encourage a classroom culture that values enquiry over transmission. Practical work is no longer just an illustration of theory; it becomes the medium through which data-handling and evaluative skills are developed. Teachers may need to allocate more lesson time to student-designed investigations, modelling, and the analysis of sample data sets provided by CCEA.
2026 年的变化鼓励一种重视探究而非灌输的课堂文化。实验工作不再仅仅是理论的例证；它成为培养数据处理和评价技能的媒介。教师可能需要将更多的课堂时间分配给学生设计的探究、建模以及对 CCEA 提供的样本数据集的分析。
Formative assessment techniques such as hinge questions and exit tickets can help identify misconceptions early. Because AO3 now carries substantial weight, pupils must be trained to critique information and justify conclusions, habits that take consistent practice to develop.
形成性评估技术，如关键问题和退出卡，有助于及早发现误解。因为 AO3 现在占有相当比重，学生必须养成批判信息和论证结论的习惯，这些习惯需要持续练习才能形成。
10. Revision Strategies for 2026 Candidates | 2026 年考生的复习策略
Effective revision for the new AS Biology cannot rely on passive reading. Start by organising revision around the specification statements, using them as a checklist. For each statement, generate at least two exam-style questions that blend AOs; for example, for the topic of enzyme inhibition, write one question that requires graph interpretation (AO2) and another that asks you to evaluate the use of statins in cardiovascular disease (AO3).
新 AS 生物的有效复习不能依赖被动阅读。从围绕大纲陈述组织复习开始，将其用作检查清单。对每一条陈述，生成至少两个融合评估目标的考试风格问题；例如，对于酶抑制这一主题，编写一个需要解读图表的问题（AO2）和另一个要求评价他汀类药物在心血管疾病中使用的问题（AO3）。
Practical skills revision should involve working through CCEA’s published practical handbook and completing past-paper Unit AS 3 questions under timed conditions. Pay special attention to the command word ‘Evaluate’ and prepare template responses that highlight accuracy, reliability, precision and validity. Always link improvements to specific apparatus, control variables or sample size.
实验技能复习应包括研读 CCEA 发布的实验手册，并在限时条件下完成往年的 AS 3 单元试题。特别注意指令词“Evaluate（评价）”，并准备突出准确性、可靠性、精密度和有效性的回答模板。始终将改进措施与具体的仪器、控制变量或样本大小联系起来。
11. Resources and Digital Tools | 资源与数字工具
CCEA provides a comprehensive package of support materials for the 2026 specification, including a full specimen paper, mark schemes, examiners’ reports on the specimen, and a detailed practical support booklet. These should be the starting point for all exam preparation. The specification itself contains a section on mathematical requirements with worked examples, which is immensely helpful for statistics revision.
CCEA 为 2026 年大纲提供了一套全面的支持材料，包括完整的样卷、评分方案、样卷的考官报告以及详细的实验支持手册。这些应是所有备考的起点。大纲本身包含一个带有解法的数学要求部分，对统计学的复习极有帮助。
Digital tools can also enhance learning. Molecular visualisation apps help with protein structure, while online quiz platforms tuned to CCEA command words strengthen recall. However, be discerning: not all third-party materials align with the new specification’s depth and style. Cross-reference any external resource against the official specification to avoid wasted effort.
数字工具也能加强学习。分子可视化应用程序有助于理解蛋白质结构，而针对 CCEA 指令词的在线测验平台能强化记忆。但要审慎：并非所有第三方资料都与新大纲的深度和风格一致。将任何外部资源与官方大纲对照，避免做无用功。
12. Looking Ahead: Future Trends in Biology Assessment | 展望：生物学评估的未来趋势
Beyond 2026, several trends are likely to grow in importance. The integration of bioinformatics—using large genomic databases to solve problems—is already appearing in optional A2 topics and may filter down to AS. Real-world data from global health organisations and climate science will increasingly underpin exam questions, demanding that students interpret graphs with confidence and recognise the limits of scientific models.
2026 年之后，若干趋势的重要性可能会增加。生物信息学的整合——使用大型基因组数据库解决问题——已经出现在 A2 的可选课题中，并可能渗入 AS。来自全球卫生组织和气候科学的真实数据将越来越多地支撑考试题目，要求学生自信地解读图表并认识到科学模型的局限性。
There is also a growing conversation around digital examinations and the use of simulations to assess practical skills. While CCEA has not yet announced a move to on-screen testing for biology, the success of pilot schemes in other subjects means that such a shift could arrive within the lifetime of the current specification. Staying adaptable and digitally literate will therefore be a lasting asset for biology learners.
此外，围绕数字化考试和使用模拟评估实验技能的讨论也越来越多。虽然 CCEA 尚未宣布在生物学中转向机考，但其他科目的试点计划成功意味着这种转变可能在本大纲的有效期内出现。因此，保持适应能力和数字素养将是生物学习者的持久财富。
