Marking

The Following is taken from Pages 35 & 36 of the Edexcel Specification

Students cannot select both their observational tasks from the same row in the observation task table. For example, not A1 and B1, A2 and B2 etc.

 

Assessment criteria

Teachers must mark the student’s work using the assessment criteria specified below. Teachers should check carefully that the students’ work is their own and is not copied from source material without any attempt by the students to put the material in their own words.
Each observational task (both aided and unaided) should be awarded a mark out of five in each of the design, observation, analysis and evaluation strands.

 

Design

Mark range
Descriptor
0
No procedure designed.
1
Outline a simple procedure for the observations, using basic astronomical terminology.
2–3
Astronomical knowledge and understanding used to decide on the most appropriate site, time, equipment for observations.
Spelling, punctuation and grammar used with reasonable accuracy. Limited use of astronomical terminology.
4–5
Detailed astronomical knowledge and understanding used to design the most appropriate observing programme with a range of sites, times and instruments evaluated.
Spelling, punctuation and grammar used with considerable accuracy. Good range of astronomical terminology used correctly.

 

Observation

Mark range
Descriptor
0
No observations completed.
1
Simple observations completed, providing some data.
A few observational details included.
2-3
Sound observations completed and recorded, providing adequate data for the task.
Clear and accurate observational details included.
4-5
Excellent programme of observations completed and recorded, providing conclusive data for the task.
Full observational details included clearly and accurately.

 

Analysis

Mark range
Descriptor
0
No analysis on the observations.
1
Simple comments on what is shown by the observations, using basic astronomical terminology.
2-3
Conclusions or calculations derived from observational data used to address the task set.
Spelling, punctuation and grammar used with reasonable accuracy. Limited use of astronomical terminology.
4-5
Full analysis of the observational data, resulting in clear conclusions related to the task set.
Spelling, punctuation and grammar used with considerable accuracy. Good range of astronomical terminology used correctly.

 

 

Evaluation

Mark range
Descriptor
0
No evaluation of the observation.
1
Simple comment on the accuracy of the observations, using basic astronomical terminology.
2-3
Supported statement of the accuracy of the observational data obtained. Feasible suggestions for improvements or extensions to the observations.
Spelling, punctuation and grammar used with reasonable accuracy.
Limited use of astronomical terminology.
4-5
Clearly reasoned quantitative assessment of the accuracy of the observational data obtained.
Detailed suggestions for improvements or extensions to the observations.
Spelling, punctuation and grammar used with considerable accuracy. Good range of astronomical terminology used correctly.

 

Marks for both the unaided and aided observation tasks should be recorded on the Controlled Assessment Record Sheet found in Appendix 5.
