DESCRIPTION
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.

Moodle quizzes to improve learning in large first year laboratory classes

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
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

Edit quiz
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
Further efficiencies in the lab
Rubric for each exercise:
Demonstrators enter marks into GoogleDocs
Tried Moodle but too slow….
Lab technician uploads marks to Moodle after each lab
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
