Question 1 [1 mark]
The library trial: a trial report [1] On Tuesday, library monitors investigated a long queue at lunchtime at the library entrance. They first watched the usual arrangements instead of immediately buying new equipment. Their notes suggested that pupils had to ask the librarian where to return books. [2] The group agreed to a clearly labelled return box. For one week, they compared what happened with their earlier notes. They recorded that the queue became shorter. The trial was encouraging: there was a noticeable improvement. However, a few pupils put borrowed books in the wrong box. [3] At their meeting, the group recommended that staff check the box before opening time. One member said, "This is the best change our school has ever made." The report did not treat that opinion as a measured result. It concluded that the change was promising, but the evidence was limited to one week. No observations yet covered a whole school year. The next trial would include this missing information before a permanent decision was made.
