Component Exemplary Basic Nonperformance General Exemplary work will not just answer all components of the given question but also answer correctly, completely, and thoughtfully. Attention to detail—as well as answers that are logical and make sense—is an important piece of this. Basic work may answer all components of the given question, but some answers are incorrect, or difficult to interpret given the context of the question. Basic work may also be missing components of a given question. Nonperformance occurs when students are missing large portions of the assignment, or when the answers simply do not make sense and are incorrect. 5 pts Plot of Positions 4–5 Plot uses correct symbology for different positions. Axes are labeled with correct Title and legend. All required points are present and in the correct locations 2–3 Plot missing some components (title, legend, positions, etc.) or has switched axes. 0–1 Multiple missing components (title, legend, positions, etc.). Missing data. 5 pts Question 1 5 Answered all of correctly. Reports the average error correctly with appropriate units. Correctly distinguishes between precision and accuracy and assigns an appropriate grade (high, medium, low). 3–4 Answered all questions, mostly correct Reports the average error correctly but missing appropriate units. Distinguishes between precision and accuracy and assigns an appropriate grade (high, medium, low) but description is incomplete. 0–2 Answered a few of the questions correctly Incorrect reporting of the error and/or missing/incorrect units. Confuses precision and accuracy and does not use the correct grade.
3 pts Question 2 3 Correctly describes and explains differences in accuracy and precision between measurements Recognizes coordinated errors. 2 Describes differences in accuracy and precision between measurements types. Struggles to articulate why time dependent. 0–1 Struggles to describe differences in accuracy and precision between measurements Cannot explain coordinated errors. 3 pts Question 3 3 points: For each of GNSS device, correctly gave the accuracy, precision, and two uses. Identified that change cannot be detected if the reported error or uncertainty is greater than the amount of change measured. 1–2 points: Answered the questions correctly but failed to either correctly attribute error to the correct source or didn’t discuss the differences in consumer versus commercial grade equipment And/Or Failed to identify change couldn’t be detected. 0–1 points: Failed to correctly attribute error to the correct source or didn’t discuss the differences in consumer versus commercial grade equipment And Failed to identify change couldn’t be detected. 5 pts Question 4 5 Correctly attributed each grade of GNSS equipment with the correct accuracy and precision. Identified that commercial grade receivers are capable of higher precision than consumer grade because of the ability to correct signal deviations Lists two uses for each grade of device 3–4 Answered the questions correctly but failed to either correctly attribute error to the correct source or didn’t discuss the differences in consumer versus commercial grade equipment And/Or Lists less than two uses for each grade of device 0–2 Failed to correctly attribute error to the correct source or didn’t discuss the differences in consumer versus commercial grade equipment And/Or Lists less than two uses for each of grade 3 pts Question 5 3 Correctly explains the value in making uncertainties explicit with all measurements. Answer articulates how large uncertainties can make hazard assessment difficult to do confidently. 2 Correctly explains the value in making uncertainties explicit with all measurements. Answer starts to explain how uncertainties can obscure confident results. 0–1 Does not provide clear or correct answers.
