IA - Teacher Support - Data Presentation
This pages provides a step by step guideline for teachers to use in the classroom in preparing the students for their internal assessment. The guideline contains a useful checklist for the students as well as exemplary material and model features.
Introducing Presentation Techniques
The following examples are all taken from successful internal assessments written by students at my school. You could present these ideas to the students and for each one discuss the successes and limitations for showing the data effectively.
A Location map of the River Lesse, showing both the location of survey sites and characteristics of the drainage basin
A Choropleth Map showing Environmental Quality
Choropleth uses colour to represent a range of data
It provides the important spatial element to the investigation
It allows easy comparison of zones.
The range needs to be chosen carefully
A Cluster Map Showing Location of Ethic and High Street Orientated Functions
Cluster maps are effective layers of data and can also be used as an overlay with a choropleth map.
Clusters show general trends of spatial patterns
Cluster maps complement the statistical technique, nearest neighbour.
An Urban Transect showing Ground floor Land use
Transect use choropleth to distinguish ground floor land use
They are drawn to scale and show the spatial trend
Link well with a chosen sample method
Can be be combined with pie chart as well as annotated
A Composite Bar Graph Showing Environmental Quality at Different Sites
Composite bar graphs show comparison across a broad range of data
They present data effectively and are eay to read
A Composite Bar Graph on Environmental Quality Along a Transect
In this case the composite graph is comparing the CB with an area of the inner city
A Radar Chart comparing Environmental Quality in Two Zones
Radar charts are impressive to look and effective for showing a range of scores.
can be used to show congestion at different times of the day as well
Good for comparing different sets of data
An Radar Chart Based on a Survey
In this case the radar chart is used to present the results of population survey where a numerical scoring system has been used
Line Graphs to Show Bipolar Survey
A simple line depicts a bipolar survey based around the perception of place in this case.
It's easy to read and ane effective technique
Cross Sectional Graphs of a River with Velocity
Cross sectional graphs show channel width, depth, cross sectional area and velocity in one technique
Excellent for comparing changing patterns across sites
Good when combined with annotated photographs of sites
Long Profile (30 meters) Choropleth to Show Surface Velocity
It's good to show how channel characteristics change at a local scale
When combined with annotation and/or a photograph it;s an excellent technique for explaining local channel factors
this graph can also be used an overlay on Google Earth
Line Graph to Show Hydraulic Radius
Simple graph, effective and easy to read
Line Graph to Show Average Velocity with Trend Line
Trend lines are useful when the line graph pattern shows significant variation
Annotated Photograph of a Survey Site
Annotated photographs and field sketches are very useful for setting the geographic context and interpreting how local factors have a influence
Criterion C - Quality and treatment of information (presentation) (1350)
- Criterion C is integrated with Criterion D in the written report
To achieve 6/6 Students should meet the following assessment criteria:
The information collected is directly relevant to the fieldwork question and is sufficient in quantity and quality to allow for in‑depth analysis. The most appropriate techniques have been used effectively for both the treatment and display of information collected.
Students should include the following:
Display of information (6-10 examples)
Students should treat and display the information collected using the most appropriate and effective techniques. This may include tables of data, graphs, diagrams, maps, annotated photographs and images, matrices and field sketches and statistical tests (including confidence limits).
Full attention should be given to the accuracy of display, with titles, axis titles and integration
How to Structure the Data Presentation
This is an important stage of the written report as it forms the basis of the analysis and is essential to the student's interpretation of information and argument. It is integrated with the analysis section of the report.
Students should consider a variety of effective techniques including graphs, tables, maps, sketch photographs and field sketches. The report is best structured in the same order as the hypotheses or subaims were stated in the introduction.
Students should use the hypotheses or subaims as subheadings within the report to inform the reader of how the presentation and analysis relates to the main fieldwork question.
Students should begin by providing the data in simple tables and graphs. Where appropriate the display of data can then become more precise and sophisticated.
For example, a student might first present a simple set of data on average channel depth in a table or graph. But this can then be followed up with a series of cross profile diagrams that show how depth varies across the channel. An annotated photograph or sketch diagram then shows the true nature of the river channel in terms of the influencing human and physical factors at the survey site.
The hypotheses may increase in complexity as the investigation continues. It is a good idea that the last hypothesis integrates more of the data so students can develop the connections across their data.
Returning to the river study the final hypothesis might refer to the changing discharge down stream as this factors connects channel depth, width, velocity and channel shape and roughness. In this way many connections and relationships can be interpreted.
