2. Enhanced Focus on Practical Endorsement | 对实验认证的重视提升

The practical component remains a cornerstone of Pre-U Science; however, from 2026 the assessment model shifts towards a ‘practical endorsement’ portfolio approach. Students will compile a minimum of twelve core practical activities over the two-year course, with direct assessment of skills such as experimental design, risk assessment, data manipulation and evaluation of uncertainty. This replaces the previous standalone practical exam paper in favour of continuous internal assessment moderated externally.

实验部分仍然是 Pre-U 科学的基石；然而，从 2026 年起，评估模式转向“实验认证”作品集方式。学生将在两年课程中完成至少十二项核心实验活动，直接评估实验设计、风险评估、数据处理和不确定度评价等技能。这取代了以往独立的实验考试试卷，转而采用经过外部审核的持续性内部评估。

3. Digital Examination Trials and Accessibility | 数字化考试试点与可及性

CCEA has announced a phased introduction of digital examinations starting in 2026 for selected science components. A pilot for the multiple-choice and data-response sections will be available on a secure online platform, offering on-screen tools such as periodic tables, formula sheets and a scientific calculator. This move aims to improve access for students with diverse needs and to familiarise learners with the digital skills increasingly required in higher education and scientific workplaces.

5. Science Literacy and Communication Skills | 科学素养与沟通技能

A noticeable shift in the 2026 mark schemes is the greater allocation of marks for ‘scientific communication’. Students will be expected to construct coherent, evidence-based arguments, interpret abstract representations and critique the validity of information from a variety of sources. This applies across all three sciences, with essay-style questions appearing more frequently, designed to assess not only knowledge but also the ability to articulate scientific reasoning clearly.

2026 年评分方案中一个显著的变化是“科学沟通”的分值比例提高。学生应能构建连贯、基于证据的论点，解释抽象表达，并批判性评价各种来源信息的有效性。这适用于所有三门科学学科，论述式题目将更频繁出现，旨在不仅评估知识，还评估清晰阐述科学推理的能力。

6. Data Analysis and Statistical Fluency | 数据分析与统计能力

Building on the emphasis on practical work, 2026 candidates must demonstrate stronger statistical fluency. The use of descriptive statistics, error analysis, correlation coefficients, and graphical representation of data sets are now explicitly specified in the assessment objectives. Students tackling investigatory tasks will need to select appropriate statistical tests and justify their choice, moving beyond simple plotting to the interpretation of significance and confidence intervals using built-in spreadsheet logic during digital tests.

基于对实践工作的重视，2026 年考生必须展现出更强的统计能力。描述性统计、误差分析、相关系数和数据集图形表示现已明确列入评估目标。处理研究任务的学生需选择合适的统计检验并论证其选择，从简单的绘图进阶到在数字化测试中使用内置电子表格逻辑解读显著性和置信区间。

7. Interdisciplinary Links Across Sciences | 科学学科间的跨学科联系

CCEA is promoting a more integrated approach to science learning. The 2026 examinations will feature synoptic questions that bridge two or more disciplines. For example, a question might ask students to apply principles of chemistry to understand biological processes such as enzyme kinetics, or to use physical concepts like wave behaviour to explain techniques in medical imaging. This rewards learners who perceive science as a connected body of knowledge rather than isolated subjects.

CCEA 正在推行一种更综合的科学学习方法。2026 年考试将包含跨两个或多个学科的综合性题目。例如，一道题可能要求学生运用化学原理理解酶动力学等生物过程，或运用波动行为等物理概念解释医学成像技术。这奖励了那些将科学视为相互联系的知识整体，而非孤立学科的学习者。

8. Updated Assessment Objective Weightings | 评估目标权重更新

The balance of assessment objectives (AOs) has been recalibrated for 2026. AO1 (Knowledge and understanding) now accounts for 35% of total marks (previously 40%); AO2 (Application of knowledge) rises to 40% (from 35%); and AO3 (Analysis, evaluation and creativity) remains at 25% but with refined descriptors. This shift underscores the premium placed on students’ ability to transfer their learning to unfamiliar contexts and to critically evaluate scientific information.

2026 年评估目标 (AOs) 的权重已经重新调整。AO1（知识与理解）现在占总分的35%（此前为40%）；AO2（知识应用）上升至40%（此前为35%）；AO3（分析、评价与创新）保持25%但描述指标有所细化。这一转变强调了学生将所学迁移到陌生情境以及批判性评价科学信息能力的价值。

9. Research Project Component in Physics | 物理学科的研究项目部分

Beginning in 2026, Pre-U Physics introduces an optional extended research project that can contribute to the final grade. Students may investigate a topic such as aerofoil design, gravitational wave detection or the thermodynamics of a domestic heat pump. The project is internally assessed and externally moderated, fostering independent inquiry, literature review skills and sustained practical engagement – attributes highly valued by universities and employers.

从 2026 年起，Pre-U 物理引入了一个可选的研究项目，可计入最终成绩。学生可以研究诸如翼型设计、引力波探测或家用热泵的热力学等主题。该项目由内部评估、外部审核，培养独立探究、文献综述技能和持续的实践参与——这些都是大学和雇主高度重视的特质。

10. Changes to Question Formats and Paper Structure | 题型与试卷结构的改变

To align with the new weightings, all written papers will undergo structural changes. There will be fewer discrete factual recall items and more structured, context-rich problems. Multiple-choice sections are reduced to 20% of the paper, while data-analysis exercises and guided open-response questions form the bulk. In addition, an ‘unseen passage’ task is being tested for Biology and Chemistry, where candidates must extract and evaluate information from a scientific article provided on the day.

为与新的权重保持一致，所有笔试都将进行结构调整。离散的事实回忆题将减少，更多结构化和情境丰富的问题将出现。选择题部分缩减至试卷的20%，而数据分析练习和引导性开放式回答问题构成主体。此外，生物和化学正在试行一种“陌生短文”任务，考生必须从考试当天提供的一篇科学文章中提取和评价信息。
