A-Level Geography: Fieldwork and the Independent Investigation

In England every A level Geography student completes at least four days of fieldwork and an independent investigation, the non-exam assessment worth 20% of the qualification; boards such as AQA and Pearson Edexcel set an advisory length of 3,000 to 4,000 words. Fieldwork methods are also examined in the written papers. This material trains the decisions that make an investigation strong, using short scenarios set in invented places.

It starts with the question itself: why a focused, located title linked to a theory, such as a river model or an urban land-use idea, is more investigable than a broad topic, and how aims, hypotheses and null hypotheses follow from it.

The largest section is sampling. You calculate a proportional stratified sample from census percentages, spot the hidden danger of systematic sampling when the interval matches a regular pattern such as beach cusps, see why simple random sampling can miss a small but important zone, and recognise the bias of an opportunistic sample taken in one place at one time.

Next come data quality and ethics. You separate precision from accuracy, using readings that are consistent but offset by a calibration error, and improve the reliability of a subjective bipolar survey with agreed descriptors and several observers. You identify what informed consent, anonymity and minimal data collection require, and choose sensible control measures in a river risk assessment.

The final questions cover presentation and evaluation: triangular graphs for three components that sum to 100%, desire lines and proportional flow lines for a sphere of influence, and judging whether a conclusion goes beyond the evidence.

The material offers a quiz with explanations, flashcards for the key terms, a printable written sheet of longer planning and evaluation tasks, and an oral exam in which an examiner asks about an investigation you have planned or completed, one question at a time, and gives brief feedback at the end. It does not write or assess your investigation for you; it helps you reason about methods so that your own choices are justified. Statistical tests are practised in the separate statistical skills material in this category.

• Frame a focused, investigable question with a theoretical and locational context
• Design random, systematic and stratified samples and recognise sources of sampling bias
• Distinguish accuracy, precision, reliability and validity
• Apply ethical principles and risk assessment to fieldwork
• Choose suitable presentation techniques for different data
• Evaluate fieldwork methods and the strength of conclusions
