Dynamic/interactive assessment has been a long time coming! It has been
almost a century since Alfred Binet suggested that assessment of the
processes of learn- ing should constitute a priority in the mental
testing movement, and over 60 years since Andre Rey made the same
suggestion. An important model that supports many contemporary
approaches to "flexible" or "process" assessment was offered by Vygotsky
in the 1920s. The ground breaking work by Reuven Feuerstein and his
Swiss colleagues on process assessment of North African Jewish children
was done in the early 1950s. In the intervening years almost every
serious psy- chometrist has, at one time or another, called for emphasis
on assessment of the of learning, rather than an exclusive emphasis on
assessment of the processes products of prior opportunities to learn.
One has to wonder why we have had to wait so long for formalization and
instrumentation of the methods for doing just that! Of course, we
psychologists like to do what we do well, and we have learned to do
static, normative assessment, especially of "intelligence," very well
indeed. Unfortunately, it is also true that dynamic/interactive
assessment has not attracted or fueled the volume of high-quality
research that is still going to be necessary if it is to survive as a
widely used supplement to static, normative testing. This volume,
incorporating a strong research base, goes a long way toward remedia-
tion of that situation.
