The types of language teacher training participants have had was the next factor to be analyzed. Five participants of the ten identified themselves as having had language teaching training. However, all participants showed they made some accommodation for language learners in their lessons by the language they used and the strategies/techniques they demonstrated during the observation. Overall, the differences between those with language teacher training and those without were not as marked as the researcher had predicted they would be. It was suggested that this might be attributed to the types of professional development that those teachers with language teaching undertook and whether or not this was a sustained learning experience with professional support and follow up or if this was a one off course. Research (Meiers and Buckley 2010) has shown that the former is more likely to lead to greater improvements in student learning and teaching skill. One possible reason for the similarities between the two group’s use of language and strategies and techniques may be that all of the participants were working in the PYP in an International Baccalaureate authorized school and had completed the initial IB Making the PYP Happen Workshop at the time of their lesson observation. In addition to the Making the PYP Happen workshop each participant on average had completed another two workshops run by the IB. These workshops may have helped to standardize participants’ understandings of the PYP. However, not all participants had completed the language based workshops offered by the IB perhaps due to the category level of these workshops and that the aim of one workshop is to create a language policy.
