Topics & Methods


* includes land uplift/GIA, land subsidence, landslides etc.

Note: Not all methods are handled in the course. Not all topic/method combinations match (e.g. tilt meters are not used for positioning)

Instructions

There are two parts to this assignment: 1) Your own report and presentation and 2) Giving feedback to others. The first part will give you 2/3 of the final grade for this part, 1/3 will come from the second part.

For the first part: Pick a topic from the table above (e.g. land uplift studied with gravity satellites or sea level surface height studied with altimery) and find two articles that have studied the chosen topic. You can use https://scholar.google.com/ or library’s search engine at https://www.aalto.fi/fi/oppimiskeskus to get started. Try to find recent articles (2010's) to start with. If you have trouble choosing the topic, please contact Mirjam.

Write your choice in MyCourses / Registrations

Write a summary report of the topic based on the two articles you found. You should also use other sources or articles to check the information you have. Optimum length for the report is four pages (approx. 1600 words, with figures), references excluded. The preferred structure of the report is:

  1. Introduction: What was the problem?
  2. Materials and methods: How can the problem be solved?
  3. Results: What did they find out?
  4. Discussion: What does it mean?
  5. (Short conclusions or summary chapter to sum it all up if you like)

Return the report to MyCourses / assignments "Report v. 1: version for feedback" by Tuesday 28.3. Don't be late, the reports are forwarded to your peers the next morning.

Prepare a short presentation (10 mins) of the topic to be presented to the whole course on Tuesday 4.4. or Wednesday 5.4. 

For the second part: MyCourses will give you reports of two other course participants to give comments and feedback to. You will comment the report with written comments in MyCourses but be prepared to ask one question after the presentation. The DL for comments is on 11.4. (after the presentations) you can also comment on the presentation in writing. The Rubric for the assessment is below and it is also built-in to the Workshop activity. You will be asked to grade revision/pass/pass with distinction. The teachers will finalize the grades.

Final version: Take the comments into account and return the final version to the Turnitin return box by 17.4. --> MyCourses / Assignments "Final version of the report"

Assessment aspect

needs revision

pass

pass with distinction

Focus and content

Misunderstandings or conflicting information,

topic explained vaguely

Clear structure exists, logical order

Clear structure with good logics and subtle transitions

Style and conventions
