While Heisenberg Is Not Looking: The Strength of "Weak Measurements" in Educational Research
Geelan, David R.
Australian Educational Researcher, v42 n3 p395-404 Jul 2015
The concept of "weak measurements" in quantum physics is a way of "cheating" the Uncertainty Principle. Heisenberg stated (and 85 years of experiments have demonstrated) that it is impossible to know both the position and momentum of a particle with arbitrary precision. More precise measurements of one decrease the precision with which the other can be measured. By "sneaking a peak" at one variable however--conducting a "weak measurement" that does not fully collapse the quantum wavefunction--and combining this with a subsequent strong measurement of the other variable, increased information of better quality can be gathered. By analogy, theories and methodological approaches could conceivably be combined in research in such a way that one does not "force [the other] into blindness" (Bauersfeld 1988). This paper offers a theoretical and metaphorical introduction to an approach. The criteria for judging its value are empirical: does it work? Does it allow research work to be done and conceptualised in ways that are valuable? That evidence will be forthcoming as this approach is adopted and tested.
