This article unpacks the key requirements, methods and evaluation techniques you need to succeed.
欢迎阅读 Year 10 WJEC 地理实地考察与实践考核必备指南。掌握这些技能不仅对考试至关重要，也能通过数据收集与分析更深入地理解世界。本文将梳理你需要掌握的关键要求、方法和评价技巧。
1. Understanding the WJEC Fieldwork Enquiry Structure | 理解 WJEC 实地调查的结构
The WJEC GCSE Geography specification requires you to complete two fieldwork enquiries. One enquiry must be in a human geography context (e.g. urban regeneration, quality of life) and the other in a physical geography context (e.g. river processes, coastal management). Each enquiry follows a clear sequence: question, data collection, presentation, analysis and conclusion.
WJEC GCSE 地理大纲要求完成两次实地调查。一次必须在人文地理背景下进行（例如城市再生、生活质量），另一次在自然地理背景下进行（例如河流过程、海岸管理）。每次调查都遵循清晰的步骤：提出问题、收集数据、数据展示、分析和结论。
2. Formulating Strong Enquiry Questions and Hypotheses | 构建强有力的探究问题与假设
A good fieldwork investigation starts with a focused enquiry question. For example, 'How does channel depth change downstream in the River Taff?' This question should be testable and link to geographical theory. You may also state a hypothesis, such as 'Channel depth increases with distance from the source.'
一个优秀的实地调查始于一个聚焦的探究问题。例如，“River Taff 的河道深度如何沿着下游变化？”这个问题应可检验且与地理理论相联系。你也可以提出假设，如“河道深度随离源头距离增加而增大”。
Use the 'Do, Think, Test, Conclude' framework to structure your thinking. In WJEC exams, you will often be asked to evaluate an enquiry question or suggest improvements.
使用“做、想、测试、结论”框架来组织思路。在 WJEC 考试中，你常常会被要求评价一个探究问题或提出改进建议。
3. Primary Data Collection Techniques | 一手数据收集技术
Primary data is information you collect yourself. Common techniques for physical geography include measuring river velocity with a flow meter, sediment angularity with a Powers scale, and beach profile with a clinometer and ranging poles. For human geography, surveys, pedestrian counts, questionnaires and land-use mapping are typical.
一手数据是你亲自收集的信息。自然地理常用的技术包括用流速仪测量河流速度、用 Powers 圆度分级量计评估沉积物棱角、以及用测斜仪和测距杆测量海滩剖面。人文地理中，调查、人流量计数、问卷调查和土地利用绘图是典型方法。
Always record data systematically in a table or on a recording sheet, noting the date, time and weather conditions.
务必用表格或记录表系统地记录数据，并注明日期、时间和天气状况。
4. Sampling Strategies for Reliable Data | 获取可靠数据的抽样策略
It is rarely possible to measure every individual. Sampling allows you to select a representative subset. The three main strategies are random, systematic and stratified sampling. Random sampling avoids bias but can miss patterns; systematic sampling (e.g. every 10th person) is easy to apply; stratified sampling ensures subgroups are included proportionally.
几乎不可能测量每一个个体。抽样让你能够选择一个具有代表性的子集。三种主要策略是随机抽样、系统抽样和分层抽样。随机抽样可避免偏差，但可能遗漏模式；系统抽样（例如每第十个人）易于实施；分层抽样确保按比例包含子群体。
For river studies, systematic sampling at regular intervals along the channel is common. For urban surveys, stratified sampling by age or gender may be used.
在河流研究中，沿河道等距系统抽样很常见。在城市调查中，可能按年龄或性别进行分层抽样。
5. Conducting a Risk Assessment | 进行风险评估
Before you go into the field, you must identify potential hazards and plan control measures. Hazards could include slippery rocks near the river, traffic during urban counts, or weather extremes. A risk assessment table records the hazard, who might be harmed, the level of risk, and how it will be managed.
在前往实地之前，你必须识别潜在危害并规划控制措施。危害可能包括河流附近湿滑的岩石、城市计数时的交通危险或极端天气。风险评估表记录危害、可能受影响的人、风险等级以及如何管控。
Example: Hazard – strong currents; Risk – drowning; Control – do not enter deep water; wear a life jacket.
示例：危害 – 强水流；风险 – 溺水；控制措施 – 不进入深水区；穿救生衣。
6. Using Secondary Data Sources | 使用二手数据源
Secondary data strengthens your investigation. You can use OS maps to identify land use, historical aerial photographs to show coastal change, or census data for population characteristics. Always evaluate the reliability and bias of secondary sources.
二手数据能增强你的调查。你可以使用英国地形测量（OS）地图识别土地利用、历史航空照片展示海岸变化，或人口普查数据了解人口特征。始终要评价二手来源的可靠性和偏差。
Online GIS platforms like ArcGIS or Google Earth offer powerful ways to visualise spatial patterns and add context.
在线 GIS 平台如 ArcGIS 或 Google Earth 提供了强大的方法来可视化空间格局并增添背景信息。
7. Data Presentation Methods: Choosing the Best Graph | 数据展示方法：选择最佳图表
Presenting data clearly is an assessed skill. The choice of graph or chart depends on the data type. Here is a quick reference:
清晰地展示数据是一项被评估的技能。图表的选择取决于数据类型。这里提供了快速参考：
| Data Type 数据类型 | Suggested Graph 推荐图表 | Example 示例 |
|---|---|---|
| Discrete categories (e.g. land use) | Bar chart or pie chart 条形图或饼图 | Percentage of each land-use type 每种土地利用类型的百分比 |
| Continuous data (change over distance) | Line graph or scatter graph 折线图或散点图 | River depth vs. distance downstream 河流深度 vs. 下游距离 |
| Flow lines and desire lines | Proportional symbols 比例符号 | Traffic volume at different junctions 不同路口的交通量 |
Remember to label axes, include units and give your graph a title. In WJEC exams, you may be asked to complete or critique a graph.
记住标注坐标轴、包含单位并给图表添加标题。在 WJEC 考试中，你可能会被要求补全或点评一个图表。
8. Analysing Data with Descriptive Statistics | 用描述性统计分析数据
asets. For example, calculate the mean pebble size at each site to compare changes downstream. Use the formula for range: Range = Maximum value - Minimum value.
分析不仅仅是描述，还包括识别趋势、异常值和关系。计算数据集的平均值、中位数和极差。例如，计算每个地点的平均鹅卵石大小以比较下游变化。使用极差公式：极差 = 最大值 - 最小值。
Spearman's rank correlation might be introduced in Year 10 to test the strength of a relationship between two variables. This is a key geographical skill.
Year 10 可能会引入斯皮尔曼等级相关系数，用于检验两个变量之间关系的强度。这是一项关键的地理技能。
9. Interpreting Results and Drawing Conclusions | 解读结果并得出结论
Your conclusion must directly answer the enquiry question and refer back to the hypothesis. State whether the evidence supports or rejects it. Avoid simply repeating the data; explain why patterns occur using geographical theory, such as the Bradshaw model for rivers or the Burgess model for urban zones.
你的结论必须直接回答探究问题并回扣假设。陈述证据是支持还是否定假设。避免简单重复数据；要用地理理论解释模式为何出现，如河流的 Bradshaw 模型或城市的 Burgess 模型。
If the results are unexpected, suggest possible reasons, like equipment error or unusual weather on the day.
如果结果出乎意料，指出可能的原因，如仪器误差或当天的反常天气。
10. Evaluating the Fieldwork Investigation | 评价实地调查
Evaluation is a high-order skill where you reflect on the limitations of your methods and data. Discuss weaknesses such as small sample size, timing of collection, or human error. Suggest specific improvements, e.g. 'Using a more precise laser measure instead of a tape measure for distance.'
评价是一项高阶技能，你需要反思方法和数据的局限性。讨论不足之处，如样本量小、收集时间不当或人为误差。提出具体的改进建议，例如“使用更精确的激光测距仪代替卷尺进行距离测量”。
Also consider the validity and reliability of conclusions. A valid conclusion measures what it set out to measure; reliability means you would get similar results if the investigation were repeated.
还要考虑结论的有效性和可靠性。有效结论衡量了既定目标；可靠性意味着如果重复调查能得到相似结果。
11. Practical Skills in the Written Examination | 笔试中的实践技能
In the WJEC exam, you will encounter fieldwork-related questions. These may ask you to describe a method, explain why a sampling technique was chosen, interpret a graph, or assess the strengths of a secondary data source. Prepare by reviewing your own fieldwork experiences, as you can often refer to them.
在 WJEC 考试中，你会遇到与实地考察相关的问题。这些问题可能要求你描述一种方法、解释为什么选择某种抽样技术、解读一个图表或评价二手数据来源的优势。通过复习你自己的实地考察经验来准备，因为你往往可以引用它们。
Command words such as 'justify', 'evaluate' and 'assess' require extended writing using evidence.
指令词如“justify”、“evaluate” 和 “assess” 需要使用证据进行扩展写作。
12. Tips for Fieldwork Success | 实地考察成功的秘诀
Plan thoroughly: know your question and methods before you go. Pack essentials: pencil, clipboard, recording sheets, first aid kit. Collect more data than you think you need; you can filter later. Annotate maps and photographs in the field to capture observations. Always evaluate your process; it shows critical thinking.
周密计划：出发前了解你的问题和所用方法。携带必需品：铅笔、书写板、记录表、急救箱。收集比你以为所需更多数据；后面可以筛选。在实地标注地图和照片以记录观察结果。始终评价你的过程；这体现了批判性思维。
These habits will not only boost your practical grade but also build confidence for the exam.
这些习惯不仅能提高你的实践成绩，还能为考试建立信心。
