7. Assessment Objectives and Weightings | 评估目标与权重

AQA sets out three Assessment Objectives (AOs) that define what you are expected to demonstrate. The same weightings apply to both Paper 1 and Paper 2.

AQA 规定了三个评估目标 (AO)，明确了你需要展现的能力。相同的权重适用于试卷一和试卷二。

Assessment Objective	Weighting	Expected Skills
AO1: Demonstrate knowledge and understanding of scientific ideas	40%	Recall facts, use correct terminology, describe theories
AO2: Apply knowledge and understanding	40%	Apply knowledge to unfamiliar contexts, interpret data, use equations
AO3: Analyse information and evaluate evidence	20%	Analyse graphs, draw conclusions, evaluate methods and validity

评估目标	权重	要求技能
AO1：展示对科学思想的知识和理解	40%	回忆事实、使用正确术语、描述理论
AO2：应用知识与理解	40%	将知识应用于不熟悉的场景、解读数据、使用方程式
AO3：分析信息并评价证据	20%	分析图表、得出结论、评价方法和有效性

AO2 questions are particularly demanding as they require you to take what you have learned and apply it to a new situation. AO3 questions often appear in the context of practical scenarios, asking you to comment on experimental design or reliability. A significant proportion of marks requires you to go beyond simple recall.

AO2 题目尤其具有挑战性，因为它要求你将所学知识应用到新情境中。AO3 题目通常出现在实践场景中，要求你评论实验设计或可靠性。有相当一部分分数要求你超越简单的记忆。

8. Question Formats and Command Words | 题型与指令词

Familiarity with question formats and command words is vital. AQA uses specific command words to tell you exactly what the examiner is looking for. Misunderstanding these can cost you marks.

熟悉题型和指令词至关重要。AQA 使用特定的指令词来告诉你考官究竟在寻找什么。误解这些可能会让你丢分。

Multiple choice questions test a broad range of knowledge and are often the most straightforward, though they can trick you with finely balanced distractors. Structured questions are broken into parts and often build up from simple recall to application and analysis. Open-ended questions require extended writing and may ask you to evaluate or suggest in detail.

多项选择题考查广泛的知识，通常最为直接，但它们可能会用精细平衡的干扰项来误导你。结构题分为若干部分，通常由简单回忆逐步上升到应用和分析。开放式问题要求扩展性写作，可能要求你详细评价或提出建议。

Common command words include:

常见的指令词包括：

State/Name/Identify: Brief factual answer, no explanation needed
Describe: Give a detailed account of what happens, what is seen, or steps in a process
Explain: Give reasons why something happens, often using scientific concepts
Calculate: Perform a mathematical operation and show working
Compare: Describe similarities and differences
Evaluate: Consider evidence, weigh up advantages and disadvantages, and give a judgement
Suggest: Apply knowledge to propose a hypothesis or explanation for a novel situation

State/Name/Identify：简短的事实性回答，无需解释
Describe：详细描述发生了什么、看到了什么或过程的步骤
Explain：说明某事发生的原因，常运用科学概念
Calculate：进行数学运算并展示步骤
Compare：描述相似点与不同点
Evaluate：考量证据，权衡利弊，并做出判断
Suggest：应用知识对新颖情境提出假设或解释

When you see ‘evaluate’, always provide a balanced conclusion supported by evidence. For ‘explain’, use the phrase ‘because’ to link cause and effect. Practise using past papers to understand exactly what each command word requires.

当你看到‘evaluate’时，始终要提供一个有据可依的平衡结论。对于‘explain’，使用‘因为’来连接因果关系。通过练习真题来准确理解每个指令词的要求。

9. How to Use the Specification for Revision | 如何利用大纲进行复习

Your specification is more than a list of topics – it is a targeted revision checklist. Print it out or keep a digital copy handy. As you revise, tick off each learning outcome to track your progress. The specification often gives precise wording that directly appears in mark schemes.

你的大纲不仅仅是一份主题列表——它还是一份有针对性的复习清单。将其打印出来或随时携带电子版。复习时，每完成一个学习目标就做上标记，以追踪你的进度。大纲中常包含直接出现在评分方案中的精确措辞。

Work through the ‘required practical’ section listed in the specification, not just the general descriptions. It tells you exactly what apparatus, techniques, and safety precautions you need to know. Many questions come from the specification notes, so never rely solely on textbooks.

仔细研究大纲中列出的‘必做实验’部分，而不仅仅是概括性的描述。它会确切地告诉你需要了解哪些仪器、技术和安全注意事项。许多题目源自大纲的注释，所以永远不要只依靠教科书。

Group your revision: start with Paper 1 topics to build a solid foundation, then move to Paper 2. Use the specification to make flashcards, mind maps, and summary notes. For mathematical skills, cross-reference with the maths requirements section. When you attempt a past paper, use the specification to identify which statement each question is targeting.

分组复习：先从试卷一主题开始建立扎实基础，然后进入试卷二。利用大纲制作闪卡、思维导图和总结笔记。对于数学技能，与大纲的数学要求部分进行交叉对照。当你做真题时，利用大纲找出每道题所针对的条目。

The specification also contains a list of chemical equations, key terms, and required vocabulary that you must be comfortable using. Ensure you can recall and apply these terms in context.

大纲还包含你必须能熟练使用的化学方程式、关键术语和必备词汇。确保你可以在上下文中回忆并应用这些术语。
