Using video to improve teaching -- and support teachers

Much of the discussion related to how new technologies can be used in classrooms in low and middle income countries focuses on the use of PCs, desktops and tablets. Less discussed, I often find, is the strategic potential of various so-called peripheral devices, which are (in my experience) typically only considered within the context of how they can be used to enhance or extend the functionality of the 'main' computing devices available in schools.

Many education systems (for better or for worse) have specific 'hardware' budgets, and, when they are looking to tap these budgets to introduce more hardware into schools, in my experience they often look to buy more of what they already have, supplemented in places by things like interactive whiteboards, or networked printers, as a complement to what is already available in a school.

When talking with educational planners contemplating how to use funds specifically dedicated to purchase computer hardware, I often counsel them to think much more broadly about what they may wish to buy with these monies, within a larger context of discussing things like how such equipment can be utilized to meet larger educational objectives, what sorts of training and maintenance support may be needed, and how the use of this technology can complement other, non-technology-enabled activities in a classroom. As part of such discussions, I often find myself attempting in various ways to challenge policymakers and planners to think beyond their current models for technology use.

One general type of gadget that I only rarely hear discussed is so-called 'probeware', which refers to set of devices which are typically used in science classes to measure various things -- temperature, for example, or the pH level of soil, or the salinity of water. Despite the increasing emphasis in STEM subjects in many countries, and what is often a rhetorical linkage between the use of computers in schools and STEM topics, I rarely find that World Bank client countries are considering the widespread use of probeware in a strategic way as part of their discussions around ICT use in schools. That said, one suspects that such an interest is coming, especially once the big vendors direct more of their attentions to raising awareness among policymakers in such places (much like the interactive whiteboard vendors began to do a half-decade or so ago).

While probeware is a new type of peripheral for many education policymakers, there is another peripheral that policymakers are already quite familiar with, and which is already used in ad hoc ways in many schools, but which rarely seems to be considered at a system level for use in strategic ways. Once you have a critical mass of computers is in place, and in place of buying one additional PC, might it be worth considering (for example) utilizing video cameras instead? Video can be put to lots of productive uses (and some perhaps not-so-productive uses). Considering three concrete examples from around the world may shed some light on how video can be used to improve teaching -- and support teachers.
