According to figures from the UNESCO Institute for Statistics, "Countries will need an extra 1.6 million teachers to achieve universal primary education by 2015 and 3.3 million by 2030". The 2013/4 Global Monitoring Report provides a useful discussion of the consequences of this deficit, as well as some strategies for overcoming it. There are, unfortunately, no 'quick fix' solutions here. We didn't get ourselves into this mess overnight, and we won't get out of it overnight either. While longer term efforts tackle this challenge in multiple ways over time, recruiting new teachers and upgrading the skills of others, it is probably also useful to ask:
How do you teach children in places where there are no teachers?
Many proposed answers to this include some consideration of the use of information and communication technologies. Some groups have offered that it may be most efficacious to simply introduce technologies that help enable students to teach themselves, bypassing teachers altogether. That is certainly one approach, but one with, to date, a rather checkered history of success in many instances (although not all), and one that is consistent with a worry that teacher union officials have expressed to me many times over the years: that many of their members fear that they are being, or will be, replaced by new technologies. Rhetoric from certain politicians (I'll refrain from adding a link or three here, but a few minutes with your favorite search engine should help you locate a number of them yourself) and projections from some ministry of finance officials (informed, one suspects, in some cases by data from the marketing departments of certain technology firms) do little to alleviate such concerns. In some cases, the introduction of new technologies undeniably *does* replace certain specific functions or roles that teachers currently perform, or have performed in the past (especially related to what are essentially clerical or administrative functions -- this replacement is presumably not always such a bad thing). In my experience, introducing new technologies in schools actually makes the role and function of teachers more central and critical, but that is perhaps a topic for another blog post.
Faced with severe, in some cases quite extreme, deficits of qualified teachers, especially in remote communities and in subjects like mathematics, science and foreign languages, many countries are in engaged in long term efforts to recruit and train more teachers and upgrade the skills and content masteries of 'low-skilled' teachers already in their system. They are exploring how ICTs can be leveraged to help in these efforts. Where there are pressing needs *now* for teachers that can not be met through conventional approaches or according to the traditional timelines dictated by the capacity and effectiveness of their teacher training institutes, there are looking to see how technologies can help reach students today in schools without qualified teachers -- or in some cases, without any teachers at all.
