5 Analysis and application of wider understanding
The six stages of the enquiry process Ask questions Collect data Process & present data Analysis and application of wider understanding Draw conclusions Evaluate the process

6 Enquiry 1: Ask questions
What are the coastal landforms? What coastal processes are operating? How is the coast used by people? How do human activities affect the coastal processes and landforms? Is coastal management successful? What are the characteristics of the sand dunes?

7 Enquiry 2: Collecting data
Remember that for one of your two investigations, one of your data collection methods must be that nominated by WJEC from Table A The second investigation must be underpinned by the nominated conceptual framework (Table B) You can use additional methods of data collection as you wish Remember that fieldwork is an excellent way to practice geographical skills

8 Enquiry 2: Coasts methodologies
Use of transects (across a feature) (2020 exam) Change over time (comparing primary data with secondary sources) Qualitative surveys (analysing perception) (2019 exam) Geographical flows (analysing flows and patterns of movement) (2018 exam) Analyse slope profiles and sediment sorting up a beach profile (measure beach profile using tape and clinometer; measure pebbles along the profile) Analyse patterns of vegetation across a sand dune or salt marsh system (measure profile across sand dunes using tape and clinometer; observe and record dominant vegetation types using a quadrat and identification chart) Consider changing coastal landforms (e.g. spit, beach) based on comparison of current evidence to historical evidence from maps/photos possibly making use of data collected during previous years (measure present day coastal landforms and compare with historic data, maps/photos; use of GIS) Investigate the value of distinctive coastal landscapes (i.e. using environmental quality assessment) Investigate perceptions of coastal flood risk or cliff collapse Investigate people’s reactions to a coastal management scheme Investigate land use conflicts at the coast (use of qualitative measures such as EIAs and questionnaires) Analyse changes in sediment size/shape as a result of longshore drift along a coastline (measure sediment size using callipers and sediment size using Power’s Scale of Roundness)

9 Enquiry 2: Borth Consider what methodologies could be used here to collect data

10 Enquiry 2: Ynyslas Consider what methodologies could be used here to collect data

11 Enquiry 2: Collecting data
Design appropriate fieldwork data collecting sheets Select appropriate locations (safety – risk assessment, ease of access, geographically sound) Select appropriate sampling techniques (random, systematic, stratified) Ensure accuracy and reliability Second point, looks a bit odd to have the comma at the end of the line . . Can we get the word ‘ease’ onto this line? Remember that students will need to justify methodologies

12 Enquiry 3: Processing and presenting
Processing data This involves making calculations from the data sheet and could involve: Calculating central tendency (mean, mode, median), e.g. pebble sizes on a beach Calculating proportions, e.g. percentages of pebble angularities or types of sand dune vegetation Calculating areas, e.g. cross sectional area of a beach or exposed side of a groyne

13 Enquiry 3: Processing and presenting
Presenting data This involves selecting appropriate methods to present data and could include: Profiles and transects, e.g. beach, sand dunes Lose the title above the diagram ‘Succession on some coastal sand dunes’ and replace with ‘Sand dune profile’ I am slightly concerned about the faint text on the diagrams – heads and axes – slide 16 has been re-done by you I think and it’s very much better. This should be replicated on all the others if possible.

14 Annotated photo showing the effects of longshore drift at Borth
Pebbles rounded by attrition and abrasion Direction of longshore drift Sediment piles up on updrift side of groyne Wooden groyne buried in places by sand and pebbles Sediment eroded from downdrift side of groyne Please use a wide red arrow for ‘Direction of longshore drift’ as this is different from the other labels which identify specific features

15 Enquiry 3: Processing and presenting
Presenting data This involves selecting appropriate methods to present data and could include: Histograms, e.g. pebble size categories along a beach In key should be Sub-rounded (capital S) and Very angular (lower case a) to be consistent (Key same as on slide 17)

16 Enquiry 3: Processing and presenting
Kite diagram showing changes in vegetation along a sand dune profile Good and much clearer

17 Enquiry 3: Processing and presenting
Presenting data This involves selecting appropriate methods to present data and could include: Pie charts Dispersion graphs You could interpret a dispersion graph by marking the median, quartiles and range

18 Enquiry 3: Processing and presenting
Presenting data This involves selecting appropriate methods to present data and could include: Using GIS to plot mean sediment size at location along a stretch of coast The key – hard to read the text. Can it be improved?

19 Enquiry 4: Analysis and wider understanding
Identify, analyse and interpret trends and patterns Apply knowledge and understanding of geographical concepts and processes to specific evidence collected Trends – changes over time, distance, etc Patterns – regular repeating distributions, e.g. linear, radial, circular

20 Enquiry 4: Describing data
When describing trends and patterns consider using the acronym ‘GCSE’: GC – general comment, describing the ‘big picture’, the overall trends and patterns S – refer to specific information/data on the graphs, maps and diagrams to support your comments E – identify and comment on any exceptions (anomalies) to the overall trend/pattern

21 Enquiry 4: Analysing data
The histogram shows that pebbles are becoming less angular (more rounded) with distance along the beach from Site 1 to Site 6. At Site 1, 65% of pebbles were either very angular or angular. This had fallen to 23% at Site 2 and to 0% at Sites 5 and 6. In contrast, the proportion of rounded and very rounded pebbles increased along the beach from 0% at Site 1, 34% at Site 3 and 88% at Site 5 There is a smaller range of pebble angularities with distance along the beach. At Site 1 there are 4 categories of angularity, at Sites 2-4 there are 5 categories and at Site 6 there are just three angularity groups. The overall trend of decreasing angularity is consistent with the direction of longshore drift. As pebbles are transported. along the coast, the processes of attrition and abrasion smooth the pebbles. Cliff erosion accounts for most of the angular pebbles at Site 1. Key on diagram – ‘Very angular’, ‘Sub-rounded’

22 Enquiry 5: Drawing conclusions
This involves synthesising (pulling together) findings to reach evidenced conclusions that relate to the initial aim of the enquiry. Here’s an example: ‘In conclusion, my results clearly show that longshore drift is operating along the coast from south to north. This is supported by the increase in beach size (cross-sectional area) and the trapping of sediment on the southern side of wooden groynes (average 45cm fall on the northern side). These results can be explained by longshore drift operating from south to north. There is also a decrease in pebble size (Site 1 average of 28cm; Site 6 average of 8cm) and angularity (Site 1 65% of pebbles were angular or very angular; Site 6 88% were either rounded or very rounded). As pebbles are transported by longshore drift, they are eroded by attrition and abrasion.’

23 Enquiry 5: Drawing conclusions
Expected trends and models are not always reflected in the real world, for example: Longshore drift does not always occur in the same direction along a beach due to changes in wind direction Storms can significantly change beach landforms in a very short period of time Human factors such as coastal management, beach profiling and offshore dredging can affect coastal processes and landforms Sand dune systems can be affected by human activities such as tourism, water drainage and farming practises

24 Enquiry 5: Drawing conclusions
The position of the tide on the beach can affect data collection and could lead to unreliable results Access may be limited to parts of the beach or sand dunes Weather conditions (e.g. storms) can affect waves, coastal processes and coastal landforms Human activity, such as management, tourism and coastal defences can affect coastal processes and landforms Two left arrow heads need to touch the box as the other two do

25 Enquiry 6: Evaluating the process
Identify the limitations of geographical evidence - accuracy, reliability and bias Reflect critically on the strengths and limitations of both primary and secondary data, methods used, conclusions drawn and knowledge gained Appreciate that stakeholders may have vested interests introducing bias.

26 Enquiry 6: Evaluating the process
How might your results be different on another day or at a different time of year (position of tides, etc)? How might an increase in the sample size or the number of sites have improved reliability? With practice, might data collection techniques have been more accurate? Was the sampling strategy appropriate? Could inaccurate diagram construction have affected your conclusions?
