Productivity in the laboratory was observed to be the best
when the resources were tied to pre-laboratory activities.
Differences in student preparation became noticeable.
Students that used the resource were able to progress through
the experiments at an increased pace, and resort to the
troubleshooting resources without direction, when needed.
Students that made little use of the resource wasted time
understanding the fundamentals and lacked direction when it
came to troubleshooting. When these students struggled the
tendency was to seek assistance from the demonstrator, rather
than work out how to use resources to find a solution. It
usually took the demonstrator a number of attempts to put the
students into a routine, in order for them to seek out resources
before asking for help.
