Abstract
Laboratory experimentation is generally considered central to science-based education. Allowing students to “experience” science through various forms of carefully designed practical work, including experimentation, is often claimed to support their learning and motivate their engagement while fulfilling specific curriculum requirements. However, logistical constraints (most especially related to funding) place significant limitations on the ability of schools to provide and maintain high-quality science laboratory experiences and equipment. One potential solution that has recently been the subject of growing interest is the use of remotely accessible laboratories to either supplant, or more commonly to supplement, conventional hands-on laboratories. Remote laboratories allow students and teachers to use high-speed networks, coupled with cameras, sensors, and controllers, to carry out experiments on real physical laboratory apparatus that is located remotely from the student. Research has shown that when used appropriately this can bring a range of potential benefits, including the ability to share resources across multiple institutions, support access to facilities that would otherwise be inaccessible for cost or technical reasons, and provide augmentation of the experimental experience. Whilst there has been considerable work on evaluating the use of remote laboratories within tertiary education, consideration of their role within secondary school science education is much more limited. This paper describes trials of the use of remote laboratories within secondary schools, reporting on the student and teacher reactions to their interactions with the laboratories. The paper concludes that remote laboratories can be highly beneficial, but considerable care must be taken to ensure that their design and delivery address a number of critical issues identified in this paper.

Notes
The term rig is commonly used to refer to an experimental apparatus that can be used by a single student or group of students at one time.
Consider, for example, an item of laboratory apparatus that is used for two 1-hour demonstration sessions each term. If this was made remotely accessible, and supported by an appropriate scheduling scheme, then instead of supporting a single school, it could support up to 125 schools (10 weeks x 5 days x 5 hours per day / 2 hours usage per school), and possibly many more if the schools existed across multiple time zones..
The work reported in this paper forms part of a broader strategy that is aiming to provide enhanced support for K-12 science education through the provision of rich remote laboratory environments. As this program is expanded it is considered critical that an effective evaluation program is in place. As such this study has, as a subsidiary objective, the objective of determining the extent to which the SLEI instrument may be appropriate in supporting this evaluation.
