In semester 1 each year, around 1600 students enroll in the major Year 1 Physics course at UNSW. Laboratory time for any given student is limited, with significant pressure to complete the laboratory activities on time. This has been problematic when students are poorly prepared. To attempt to remedy this, pre-lab quizzes were introduced in 2011. Along with the questions, quizzes have accompanying supporting materials such as videos that introduce the students to the important concepts covered and equipment used during the laboratory sessions. The pre-lab quizzes have resulted in students being significantly more prepared for their laboratory sessions, allowing the demonstrators to maximize the time they spend helping students. It has also reduced greatly the need to mark preliminary work at the beginning of laboratory sessions. Students are now better prepared and better able to complete the laboratory exercises within two hours. Further, moving the safety induction online has released an extra week of laboratory time to introduce a new experiment. Thus, the use of Moodle quizzes has enhanced efficiency and quality of laboratory learning and teaching. This approach is being embraced by other schools within the faculty, such as Chemistry, for use with large first year classes. To further diversify and enrich these activities, an advanced quiz question type, which will allow for calculated questions including randomized quantities such as different planets or chemicals, is planned for development.
1. Moodle quizzes to improve learning in
large first year laboratory classes

2. The Problem in general
Large student numbers (1600 in semester 1)
• labs must run efficiently,
• if students finish late it disadvantages students in the next class
When preparatory work was in the lab manual
• Students would copy each other
• Students came unprepared for class
• Demonstrators mark preparatory work in lab rather than helping students
• Safety induction talk given 17 times during first week by one staff member
3. The solution
Students complete prework online before coming to class
Prework consists of reading over the lab manual, watching a video, a few additional
resources and then a prework test.
The test counts as 25% of their lab mark, each test is 0.5% of their total physics mark,
students get helpful feedback as they complete the test; formative assessment.
The test shuts down as soon as their lab session starts (group overrides)
Safety induction moved online, video and then a test
19. Does it work?
Students feel that they are better prepared for class
Demonstrators report that the labs run much more smoothly
The number of labs running overtime has been reduced
Random numbers mean that even if students get help they need to enter it into their own
calculator, reduced plagiarism
21. Demonstrators enter marks into GoogleDocs
Tried Moodle but too slow….
Lab technician uploads marks to Moodle after each lab
22. Current limitations of
Moodle
A pendulum is located on Mars/Jupiter/Saturn…
Mars/Jupiter/Saturn has a mass of ….. kg and a radius
of …. m.
What is g on Mars/Jupiter/Saturn?
___________ ms-2
What is the period of a spring on Mars/Jupiter/Saturn
with a spring constant of …. N/m with a hanging mass
of …. kg attached to it?
___________ s
What additional mass would you need to add to
double this period?
___________ kg
Question types are fairly
limited.
Can not easily ask questions

• Mindmaps
• WIRIS STEM questions
Wish list
• Draw a vector
• Drag, drop, rotate and resize a shape
• Bookmark a segment and area of
screen in a video
• Conditional upon current score
New question types of interest
24. Trials (soon)

Future Quiz developments
25. The future of online quizzes at UNSW
Blended Learning institution: Moodle augments campus experience.
Ask questions that enhance campus experience.
UNSW capacity and track record for enhancements relying on:
• Modular, Open Source software
• LMS provider relationship
• Institutional LMS Advisory group
• Faculty team: executives, academics, designer, technologist, programmer
• Faculty facilities: servers, access to live identities
• Moodle community: user-contributions

Would be better to do this part live…. Screenshots as back up. Mention that I go to the first lecture for all students and tell them how to use it, plus the administration forum.
Again better live.
This is an experiment that we were able to add because of the time freed up with the safety induction. Students had found the rotation topic very hard in the past so adding a lab exercise gave them more chance to engage with it in class time and has improved their results.
Continual marking through lab, more consistency across labroatory demonstrators
Only way to currently ask questions like this is to set up a very large question pool of cloze questions….
