剑桥国际AS Level计算机科学资格证书（教学大纲代码9618）将从2026年考试起发生重大变化。这些更新反映了计算机科学教育的不断演变，更加重视实际编程技能和计算思维。作为学生或教育工作者，理解这些变化对于有效备考和教学至关重要。本文将探讨教学大纲的关键修改、评估结构以及将塑造2026年及以后AS计算机科学体验的新兴趋势。
1. Overview of the 2026 Exam Changes | 2026年考试变化概览
Cambridge International released an updated syllabus for 9618, with first examination in 2026. The most notable change is the adoption of Python as the mandatory programming language for both AS Paper 2 and A Level Paper 4. Additionally, the syllabus content has been refreshed to include contemporary topics while removing outdated ones. The assessment weightings for different objectives have also been adjusted to better measure practical problem-solving abilities.
剑桥国际发布了9618的更新大纲，首次考试年份为2026年。最显著的变化是采用Python作为AS试卷2和A Level试卷4的强制编程语言。此外，大纲内容已更新，纳入了当代主题，同时删除了过时的内容。不同评估目标的权重也进行了调整，以更好地衡量实际的问题解决能力。
2. Python as the Sole Programming Language | Python成为唯一编程语言
Starting in 2026, candidates must use Python for all programming tasks in Papers 2 and 4. Previously, schools could choose from Java, Visual Basic, or Python. This change simplifies assessment and ensures consistency. Python’s readability and widespread use in higher education and industry make it an ideal choice. Students will need to be proficient in Python syntax, data structures, and standard libraries.
从2026年开始，考生必须在试卷2和试卷4的所有编程任务中使用Python。此前，学校可以从Java、Visual Basic或Python中选择。这一变化简化了评估并确保了统一性。Python的可读性及其在高等教育和工业界的广泛使用使其成为理想选择。学生需要熟练掌握Python语法、数据结构和标准库。
3. Implications for AS Paper 2 – Problem-solving and Programming | 对AS试卷2——问题解决与编程的影响
Paper 2 now exclusively tests Python programming. The paper still assesses algorithm design, debugging, and code comprehension. However, students will encounter Python-specific constructs such as list comprehensions, dictionaries, and built-in functions like enumerate(). The exam may include questions requiring code completion or output prediction purely in Python. Knowledge of other languages is no longer required, allowing deeper focus on a single language.
试卷2现在只测试Python编程。该试卷仍然评估算法设计、调试和代码理解。但是，学生将遇到Python特有的结构，如列表推导式、字典以及像enumerate()这样的内置函数。考试可能会包含需要纯粹使用Python完成代码或预测输出的题目。不再需要其他语言的知识，从而可以更深入地专注于一门语言。
4. Syllabus Content Updates and Key Shifts | 教学大纲内容的更新与关键转变
The revised syllabus incorporates new topics while retiring some older ones. The table below highlights key additions and removals.
| New/Enhanced Topics | Removed/Reduced Topics |
|---|---|
| Cybersecurity fundamentals (e.g., phishing, encryption) | Magnetic tape storage |
| Ethical and social implications of AI | Binary-coded decimal (BCD) arithmetic |
| Internet of Things (IoT) concepts | Detailed low-level printer mechanics |
| RISC vs. CISC architectures (clarified) | Overlap with legacy network protocols |
修订后的教学大纲包括了新的主题，如网络安全基础（例如网络钓鱼、加密）、人工智能的伦理和社会影响、物联网（IoT）概念，并更清晰地阐述了RISC与CISC体系结构。同时，一些旧内容如磁带存储、二进制编码十进制（BCD）算术、低层次的打印机机制以及与遗留网络协议重叠的部分已被移除或缩减。这些更新确保课程内容保持现代性和相关性。
5. Adjustments in Assessment Objectives | 评估目标的调整
The assessment objectives (AO1: Knowledge with understanding, AO2: Application, AO3: Evaluation) have been reweighted. AO2 and AO3 now carry greater weight to reflect the practical nature of the course. In Paper 1, more marks are allocated to scenario-based questions that require application of theory. This shift encourages students not just to recall facts but to analyze and solve real-world problems.
评估目标（AO1：知识理解、AO2：应用、AO3：评价）的权重已重新分配。AO2和AO3现在占有更大比重，以反映课程的实践特性。在试卷1中，更多分数分配给了需要应用理论的情景题。这一转变鼓励学生不仅回忆事实，还要分析和解决真实世界的问题。
6. Enhanced Focus on Computational Thinking | 对计算思维的加强重视
Computational thinking—decomposition, pattern recognition, abstraction, and algorithm design—runs throughout the updated syllabus. Students will be expected to apply these skills in both theory and programming contexts. For example, Paper 1 questions might ask how abstraction is used in a given scenario, while Paper 2 requires designing an algorithm using these principles. This prepares learners for modern software development and AI fields.
计算思维——分解、模式识别、抽象和算法设计——贯穿整个更新大纲。学生将需要在理论和编程情境中应用这些技能。例如，试卷1的题目可能询问在给定场景中如何使用抽象，而试卷2则需要运用这些原则设计算法。这为学习者从事现代软件开发和人工智能领域做好了准备。
7. Impact on Teaching and Learning Approaches | 对教学方法的影响
Educators must adapt their pedagogy to the new requirements. The exclusive use of Python means that classroom practice should immerse students in Python from the start. Project-based learning and code reviews become more prominent. Teachers may need professional development to stay current with Python’s advanced features. Emphasis on computational thinking also calls for more unplugged activities that build logical reasoning before diving into code.
教育工作者必须调整教学方法以适应新要求。Python的独家使用意味着课堂实践应该从一开始就让学生沉浸于Python。基于项目的学习和代码审查变得更加突出。教师可能需要进行专业发展培训以跟上Python的高级特性。对计算思维的重视也要求在开始编程之前有更多不插电的活动来建立逻辑推理。
8. Preparation Strategies for AS Students | AS学生的备考策略
Students should start using Python as early as possible, moving beyond basic syntax to libraries like math, random, and string. Practice with past papers or specimen papers in the new format is crucial. Focus on writing pseudocode and then translating it to Python to strengthen algorithm skills. Additionally, stay informed about current computing trends, as Paper 1 may include questions on emerging technologies like AI ethics. Regular coding challenges and peer reviews will build confidence.
学生应该尽早开始使用Python，从基础语法扩展到math、random和string等库。以新格式训练历年试卷或样卷至关重要。集中练习编写伪代码然后将其翻译为Python，以加强算法技能。此外，要了解当前的计算机趋势，因为试卷1可能包含关于新兴技术（如AI伦理）的问题。定期的编程挑战和同伴评审将建立信心。
9. Changes in Resources and Support Materials | 资源与支持材料的改变
Textbook publishers are releasing updated editions aligned with the 2026 syllabus. Online platforms offer Python-specific exercises and autograding tools. The Cambridge School Support Hub provides new schemes of work, example candidate responses, and teacher guides. Students should select resources that explicitly mention the 2026 syllabus. It is also beneficial to use interactive coding environments to simulate exam conditions.
教科书出版商正在发布与2026年教学大纲一致的新版本。在线平台提供Python专项练习和自动评分工具。剑桥学校支持中心提供了新的教学方案、考生答题范例和教师指南。学生应选择明确提及2026年大纲的资料。使用交互式编程环境来模拟考试环境也是有益的。
10. Broader Trends in Computer Science Education | 计算机科学教育的更广泛趋势
The 2026 changes mirror a global shift towards Python as the lingua franca of introductory programming. There is also a trend to integrate ethics and societal impact into computing curricula. AS Computer Science is increasingly seen as a foundation for data science, machine learning, and cybersecurity careers. The revised syllabus aligns with industry demands, ensuring that learners acquire relevant, future-proof skills.
2026年的变化反映了全球转向Python作为入门编程的通用语言的趋势。同时，也有将伦理和社会影响融入计算机课程的趋势。AS计算机科学越来越被视为数据科学、机器学习和网络安全职业的基础。修订后的教学大纲与行业需求保持一致，确保学习者获得相关的、面向未来的技能。
11. Predicted Challenges and How to Overcome Them | 预期挑战及应对方法
One major challenge is the transition period for schools that previously used Java or Visual Basic. Converting existing resources and retraining staff takes time. Students may face difficulties with Python’s dynamic typing if they are used to static-typed languages. To mitigate this, schools should start introducing Python in preceding years and run mock exams under new conditions. Collaboration between teachers within and across schools can ease the transition.
一个主要的挑战是对于之前使用Java或Visual Basic的学校的过渡期。转换现有资源和重新培训员工需要时间。如果学生习惯了静态类型语言，可能会对Python的动态类型感到困难。为了减轻影响，学校应该在前几年开始引入Python，并在新条件下举办模拟考试。校内和校际教师之间的合作可以缓解过渡。
12. Conclusion: Embracing the Future of AS Computer Science | 结论：拥抱AS计算机科学的未来
The 2026 AS Cambridge Computer Science syllabus represents a forward-thinking step that equips students with relevant programming expertise and critical thinking abilities. While change can be disruptive, the focus on Python and computational thinking brings the qualification in line with university and employer expectations. By staying proactive and utilizing available resources, students and educators can turn these changes into opportunities for deeper learning and success.
2026年AS剑桥计算机科学教学大纲代表了具有前瞻性的一步，使学生具备相关的编程专业知识和批判性思维能力。尽管变化可能带来暂时的混乱，但对Python和计算思维的重视使该资格证书与大学和雇主的期望保持一致。通过保持积极主动并利用可用资源，学生和教育工作者可以将这些变化转化为深入学习和成功的机会。
