The possible uses of computers for school practical work continue to increase, both as a means to enhance practical work and to support simulations as an analogy of practical work. Simulations have been more readily adopted in aviation training (Salas, Bowers, & Rhodenzer, 1998) and in medical education (Bligh & Bleakley, 2006; Issenberg, McGaghie, Petrusa, Gordan, & Scalese, 2005; Ziv, Ben-David, Ziv, 2005), but the use of simulations for schools has only become more prevalent in the last decade (Rutten, van Joolingen, & van der Veen, 2011; Scalise, Timms, Moorjani, Clark, Holtermann, & Irvin, 2011). However, the use of simulations for schools continues to expand.
Since the advent of simulations in education, various different terminology has been used to describe the particular types of simulation and how they link with the object being simulated, e.g., simulation of practical work. Clements (1999) draws on the idea of 'concrete' from concrete manipulatives, in terms of a Piagetian pedagogical sequence moving from 'concrete to abstract', and offers a re-formulation that encompasses computer manipulatives. However he notes potential issues in agreement of equating 'concrete' with physical manipulatives and 'accepting objects on the computer screen as valid manipulatives' (ibid, p.49). Despite these issues he notes that research has shown that 'computer representations may even be more managable, 'clean', flexible, and extensible than their physical counterparts' (ibid, p.49). Based on the research, what is 'concrete' is in 'the eye of the beholder' (ibid, p.50).
Zacharia (2007) uses the terms Real Experimentation (RE) and Virtual Experimentation (VE) to distinguish between practical work and practical work simulations. Zacharia and Olympiou (2011) introduce the terms Physical Manipulative Experimentation (PME) and Virtual Manipulative Experimentation (VME), thus highlighting the terms to distinguish types of experimentation are still open to debate. When it comes to experimentation, it could be argued that the addition of 'manipulative' is unnecessary, as manipulation is an inherent aspect of experimentation. It is also pertinent to note the change of the term ‘real’ (Zacharia, 2007) to ‘physical’ (Zacharia & Olympiou, 2011). From a philosophical perspective, virtual experimentation could be argued as a ‘real’ student experience (Zacharia & Olympiou, personal communication, 07/09/2011) and hence, the change of real to physical. However, it could also be argued that virtual experimentation involves a ‘physical’ student experience with a computer. There is clearly an issue in defining the interpretive boundaries of virtual, physical, and real in relation to experimentation. One could fall into a matrix of experimentation terminology. What is real? What is virtual? What is physical? Such a debate falls in line with Clements (1999)'s argument that determining what is 'concrete' is based on each individual's perception. The debate could be complicated further by considering other terminology such as artificial experimentation, actual experimentation, simulated experimentation. Put me back inside the Matrix where things are simpler!
Unfortunately, there are bigger issues of concern in schools in that many students' experience of supposedly 'real' practical work is rather 'artificial' or 'simulated' where students simply follow steps in a cookbook manner to a known conclusion (Abrahams & Millar, 2008). Such practices reflect little in aiding to develop students' scientific reasoning and understanding of what scientists do. The focus of enhancing practical work needs to move beyond issues of just physicality (hands-on) to consider the meaning students derive from practical work (minds-on). An exellent 'concrete' activity is an excellent mental activity (Clements, 1989; Kamii, 1989). Such activities for learners are meaningful, provide ownership and flexibility, align with cognitive processes, and overall assist in a greater knowledge integration (Clements, 1999).
