Teachers’ Views of their Primary School Classrooms: Referees’ Comments and Authors’ Responses Referees’ comments Reviewer 1 The study is interesting, because is important to the scientific community to know the opinion of key actors in schools, as the teachers. Abstract – rephrase the sentence: “The teachers appear to be aware of the “hard” aspects of the physical environment, but less conscious of the impact of “softer” aspects, especially the level of stimulation created” Authors’ responses Agreed. Agreed and changed. should be “The teachers appear to be aware of the “hard” aspects of the physical environment, but less conscious of the impact of “softer” aspects, especially those with impact on the level of stimulation created” Page 6 “Of course this is a view from a group of teachers, but it does raise an interesting question to be addressed through further research: “is our school design improving and is it building on the lessons of the past?” I think the question is very simplistic, because the characteristics of the buildings were adapted to the reality of each period. I think it would be useful to the relationship between the density of occupation (and perhaps also the volume) classrooms and age schools. Page 16 – table 5 The sentence “Also, more electrical lightning with higher quality can provide a better visual environment” is also arguable, being in terms of health, being in terms of energy efficiency. It should be preferable to provide a better visual environment using natural light and using appropriate tools for attain it. Reviewer: 2 In general, valuable information about classroom conditions can be obtained by interviewing teachers. We can see the point being raised here, which is essentially what is it about, especially 1950s classrooms, that teachers seem to like? As this is a qualitative paper for which the basis is the views of the teachers, we have actively responded to this query by tracking across the characteristics and identified those where particularly low problem scores are evident for 1950s classrooms in contrast to the later schools. We have also removed the polemical question as inappropriate (sorry about that) and replaced it with a more objective observation about not assuming old is bad. We know what is being suggested here and if good quality natural lighting could provide sufficient light for the whole of the school day / year that might well be the ideal. However, in practice there are parts of the classroom, times of day and times of the year when the natural lighting is not sufficient and this is where the need for good quality artificial lighting is essential. In Table 5 this comes in the left-hand column and is in fact a finding given and justified in an earlier paper regarding impacts on learning (see note 1 to the table). The right-hand column does highlight that teachers appear to underestimate the importance of daylight. For these reasons and in this context we feel the text should stand. Agreed, but it has implications for the nature of the analysis that is possible, which is a recurrent theme below. The analyses should take into account the clustered nature of the data: teachers from the same school are more likely to report similarly then teachers from different schools. Also seasonal variation should be considered, since the interviews were conducted over one year period. For example thermal conditions and perception of indoor air quality are likely to change by season. Other important confounding factors are not considered, such as teachers' characteristics (e.g. age, gender, level of education and experience, years working in the same classroom). Sample size limitations need to be discussed. The format of some questions presented in Table 1 appears unclear, so I would suggest adding some discussion about the formulation of the prompts. Are these validated questions or are there any references? I would find it interesting to relate the subjective perception of the teachers to objective measurements of classroom thermal conditions, indoor air quality, noise, and lighting, but it is unclear if any such measurements were done. Connections to pupils’ learning progress are not well explained and it leaves it open how these results were obtained and/or how they relate to the current work. … It appears that the paper describes one part of a larger study, but it is not clearly presented so the reader cannot easily put this piece of work into a larger context. The issue of seasonal variation was one of the key reasons for interviewing teachers about their experience of the classroom over the whole year. We have highlighted this in the text to reinforce this point. We did in reality gain useful information across the seasons from the individual teachers, for example, overheating in the Summer and problems with cold in the Winter. On the suggestion that teachers from the same school are likely to report similarly, this is something that we can’t test per se as this is not a statistical study (see next box below). But we do discuss some aspects that seem to reflect common school characteristics in 3.2 and note there that we also found quite considerable variations in some cases too. We did not collect demographic data about the teachers as the driving force for the sample selection was to provide diversity in the classrooms (we have amended it from schools) analyzed so that the findings about the teachers’ views would be independent of any particular school type. This mirrors Marten (2002)’s approach and is explained in section 2.2. As to sample size, it would seem uncontentious that although 222 would only be a moderate sample size for a questionnaire survey, it is a large sample for face-to-face interviews with qualitative analysis based on detailed notes of the discussion. The questions included covered areas that seem likely to emerge based on our previous POEs etc, but they were there as a back up after an initial general enquiry. Apologies we had missed this last out from Table 1 before, so we have now added this and deleted one column as superfluous making the table simpler and clearer. The associated text has been augmented to reflect these changes and to mention that a Likert scale was used for the final question. We do not have the data to do this as only spot measures were taken and as distinct from the views over the whole year that were sought from the teachers. However we do compare a more measurement-based, statistical analysis of the classrooms, published in a previous paper and summarized in the Introduction, with these subjective users’ views in the final Table 5 and comment as to synergies and differences. The measurement-based, statistical analysis and results regarding pupils’ learning are freely available in a previously published paper in “Building and Environment”. We have briefly summarized them in the Introduction as they were part of the same study as these results and the thrust of the paper is to give visibility to the teachers’ views alongside this complementary methodology. The second paragraph of the Introduction makes this relationship between the parts of the HEAD study explicit. We do think this is clear, but are open to suggestions.
