In an attempt to overcome this problem, the theoretical framework of situated cognition or situated learning has been used in this project to design an interactive multimedia resource that allows preservice teachers to become aware of different assessment strategies in mathematics education and how to apply them. The resource enables users to encounter the authentic use of a range of assessment strategies and to view their interpretations from multiple perspectives which include the teacher's decision-making processes, the child's thinking, expert opinion and written documentation.
The interactive multimedia package described in this paper goes some way towards providing perspectives on mathematics education that may provide students with the confidence to implement approaches that are appropriate for assessing the range of outcomes that are valued in the learning of mathematics.
|Student Teacher:||This is my lesson plan for tomorrow. I'll need to think about assessing the way the students solve problems?|
|Teacher:||And how do you think you might do that?|
|Student Teacher:||Well, I could try putting them in groups and using a checklist but I'm not sure that will work. When I was in school the teacher would simply give us a test. I think I'll do that.|
|Teacher:||Why not give it a go? Perhaps you could list some approaches that you think the students might use when they solve the problems and make a checklist up that way.|
|Student Teacher:||Well, I'd feel safer using a test. I'm not sure what strategies they might use. I haven't actually seen anyone using a checklist in class before.|
This script is contrived but, we contest, not unique. It is accepted wisdom in teacher education circles that teachers teach the way they were taught and that innovative approaches are not widely employed.
Several writers have expressed concern that despite the emphasis in teacher education courses on 'reformist' methods of teaching mathematics, teachers revert to methods of teaching derived solely from their own experiences as students (Ball, 1994; Lampert & Ball, 1990). Others have noted that preservice teachers' experiences in classrooms during their practicum have proved inadequate because often students observe teaching 'driven by texts and tests', or are ill equipped to detect the subtle differences between quality and mediocre teaching (Mousley & Sullivan, 1995). Despite the variety of innovative and effective assessment techniques, teachers generally continue to limit their means of assessment to a narrow range of pencil-and-paper methods (NCTM, 1995; AEC, 1991).
The reasons, as we see it, stem from the belief that much of what goes on in teacher education courses involve tasks that require students to process knowledge that is not linked to situations in which the new knowledge will be applied. Consequently, the knowledge and abilities that are learnt have little chance of transfer to real classroom situations. The problem then becomes one of creating links between what the learners know and the situations in which they plan to use it.
There are many ways in which these links can be made. It would appear that teaching practice is a useful way of enabling student teachers to apply knowledge gained from their teacher-training courses. Unfortunately, given a scenario similar to the one described above, this situation may not provide an environment where a student teacher can explore and experiment with theoretical approaches in a real context.
An environment that enables exploration can be provided by multimedia. Recent advances in computer technology allow for the storage of large amounts of data in the form of visual, audio and text formats. These formats allow for multiple perspectives and representations of ideas to be easily accessible and interactive.
The approach that we have taken is to use current theories of learning, in particular the notion of situated cognition or situated learning, as a framework for designing interactive multimedia that allows student teachers to become not only aware of different assessment strategies in mathematics education, but also to gain the conditional knowledge of when it is appropriate to apply them in the real context of the classroom.
Brown, Collins and Duguid (1989) were the first to use the ideas to produce a proposal for a model of instruction that has implications for classroom practice. Their theory was first expounded in the article: 'Situated cognition and the culture of learning' which appeared in the Educational Researcher in 1989. Collins (1988) defines situated learning as: 'the notion of learning knowledge and skills in contexts that reflect the way the knowledge will be useful in real life' (p.2). In proposing their model of situated cognition, Brown et al. (1989) argue that meaningful learning will only take place if it is embedded in the social and physical context within which it will be used. A critical aspect of the situated learning model is the notion of the apprentice observing the 'community of practice'. Lave and Wenger (1991) proposed that participation in a culture of practice can, in the first instance, be observation from the boundary or 'legitimate peripheral participation'. As learning and involvement in the culture increase, the participant moves from the role of observer to fully functioning agent.
McLellan (1994) summarises the key components of the situated learning model as: apprenticeship, collaboration, reflection, coaching, multiple practice, and articulation of learning skills (p. 7). However, the model is constantly evolving and recent contributions of various theorists and researchers, including the original authors of the model, have expanded and refined the notion to a much more comprehensive and far-reaching framework for classroom application. Many of these authors and theorists believe that useable knowledge is best gained in learning environments which feature the following characteristics (Herrington & Oliver, 1995):

The instruction book for facilitators suggests ways that the resource can be used and advises on the role of the lecturer. A number of challenging activities are provided which enable students to make an initial exploration into the package. The package is not designed for students to progress in a linear fashion, but attempts to stimulate students' to ask their own questions and instigate their own investigations.
|Oral reports||Written report, eg., project or investigation|
|Portfolios||Pencil and paper test|
|Problem solving test||Practical test|
|Multiple choice test||Self assessment through journals|
|Projective assessment||Interviewing or conferencing|
|Newman Error analysis||Oral Questioning: higher order|
|Oral Questioning: fact recall||Using open-ended questions|
|Attitude test||Students writing their own questions|
These strategies are grouped within broader categories of assessment such as teacher observations, teacher questioning, testing, interviewing, student reporting and student self assessment.
Twelve mornings were scheduled in eleven different schools to videotape the central video scenes of the assessment types in the classroom. The video recordings of the teachers' and students' comments also needed to be taped immediately after the video so that their thoughts on the task were fresh in their minds. If any materials were integral to the scene they were collected for scanning.
The video equipment was minimal, consisting of a betacam camera, a tripod, three lights and a portable microphone. The crew consisted of two people: the video producer and a sound recordist. The video sequences were filmed in the teacher's normal classroom, but some reorganisation was often required for the teacher to retain the same room for the whole morning. The scenes were shot and edited in most cases within a week of filming.
At the same time, the project needed to consider the advantages of a dual-platform delivery system. While the initial programming and graphics design was to be carried out using a Macintosh system, we recognised that in some instances, potential users may wish to use the program on other platforms. It was recognised that developing a dual platform product would increase its potential use and application beyond the immediate setting. A decision was taken to apply standard programming techniques and to use processes and extensions in the development that were compatible with cross platform delivery.
