The goal of this project

This two-part assessment is designed to provide prompt formative feedback to students without increasing teacher workload. Providing feedback to groups of students proved to be an efficient and scalable model that supports student learning while not imposing on teacher time.  An assessment FOR learning approach allows students to address misunderstandings and misconceptions before submitting their individual lab report. 

 

ARTEFACT 1

Assessment overview with intro video

 Students were provided with three components in Canvas:

 

Canvas assignment module showing the three parts: overview, part 1 and part 2.

 

Learner-centered information

This assessment was structured and written to support student learning.

The overview and instructions were written for the web. Where appropriate, instructions were in bullet points to make it easier for students to understand. 

The image on the left provides an example of how to provide instructional content in assessments.

  • Use bullet points where possible when communicating directly.
  • Use meaningful headings to chunk information.
  • Keep your communication clear and unambiguous.

 

 

The Fluid Mechanics Lab overview in Canvas was laid out in the following way:

Learning Outcomes

  1. Understand how fluid flow in the real world includes some energy lost to the surrounding environment that are not negligible.
  2. Understand the effects of friction and pipe roughness on the energy lost by the fluid flow.
  3. Understand how different pipe fittings affects the loss factors for the flow of a Newtonian fluid in the pipe.
  4. Understand and apply the modification to Bernoulli’s equation may be used to design the flow of fluid within a piping system.

This lab has been designed in two parts to support your learning. 

Part 1: Group

  • During the lab you will work in groups of four to complete the experiment, record measurements and complete calculations.
  • At the end of the lab (or within two hours of the lab finishing) you have an opportunity to submit your group calculations for feedback.
  • This submission is formative only and has no grade attached.
    It is designed to support your learning and allow for any corrections you might need to make to your calculations for the individual report in Part 2. 

Part 2: Individual

  • Having received feedback as a group, you can now complete and submit your individual lab report.

ARTEFACT 2

Formative Group Work with Feedback

<Logistics on the group set up goes here>

Steps for completing this assessment:

    1. Watch the corresponding lab demonstration video and lab manual located within the Laboratory Module to familiarise yourself with the experiment.
    2. Check your Lab Group via the Canvas Announcement or here: (link here)
    3. Attend the lab allocated to your group. 
      We will discuss the experiments and the expectations in completing the lab report.
    4. At the end of the lab or within 2 hours of the lab finishing, submit your group calculations for feedback via this portal.

Submission formats:

  • a digital photo of handwritten calculations or
  • a PDF if calculations were completed electronically e.g., on a Surface Pro

After the group submission you will receive feedback on your group's calculations within 24/48 hours which you can use to complete your individual lab report. 

NOTE: while this submission is ungraded, the feedback you receive is designed to help with your individual report.

 

 

ARTEFACT 3

Summative individual report submission

 

Experiment F1-22:  Energy Losses in Pipes

Bernoulli’s equation is commonly used to describe the flow of a fluid in ideal conditions, but real-world situations include some energy losses. To determine the loss factors for flow through a range of pipe fittings including bends, a contraction, an enlargement and a gate-valve, this experiment measures the head differences across pipe fittings connected in series over a range of steady flows.
