Let just take a moment to savor a basic fact: it was a randomized experiment. makes you smart then it might as well not be randomised, with respect to that specific hypothesis?No, the randomization still serves for causal inference, it just means the identified causes are a mix of potential causes like direct effect of art and expectancy effects. maybe the kind of children who have parents that choose art vs. Air Max One Yeezy
Some of the work stemming from Pearl causality formalism has been about conditions under which one can make causal inference even in the absence of an explicit randomization step, and one can attack it from another direction by compiling correlations which have been later examined with randomization, and estimating how many of the correlations turned out to be causation in the same direction (the numbers tend to look like 10%) and how much they are due to other factors.> Isn [potential selection bias etc.] just as bad as [potential expectancy effects etc.]No. Expectancy effects can be manipulated and measured and one could arguably then adjust for it in other results where expectancy is mixed in. It a fact about human psychologies, as measurable as anything else there. Selection effects are too wild and unpredictable to hope to do such a thing.
to the type of content they were exposed to during the field trips, because as such the test is also measuring their exposure to that content (art criticism and analysis) and its style. To compare to baseball again, it would be like sending kids to baseball camp and then testing those who went to camp against those who didn in a test where they were asked to write an essay about promising 2014 rookie players, and then claiming that good results in essays about baseball from the baseball camp goers was evidence the baseball camp created gains in general critical thinking skills. Maybe it did but such a test tightly connected to the particular subject matter that one group was exposed to and the other was not is not a reasonable way to assess general critical thinking skills.

Experiment, but the design seems to preclude that. Not clear if the pupils within each school were selected through student ID numbers or similar or left to school groups?PS: The Isabella Stewart Gardner Museum has regular classical music concerts that are downloadable as mp3s, classified by composer. Very useful resource as they are CC licensed.
Spot on analysis, Thanks for this. We also asked them to write an essay in response to a work of art that was unfamiliar to them. Having said that, the title of the article really seems like a stretch.
The link in the article has more detail, which includes an expanded "critical thinking" section. I must have missed that link. The benefits as described there seem a lot more impressive.

Nice study as an example for statistics teaching, shades of the Lanarkshire Milk Air Max Plus 97
This is a reasonable preliminary study but the conclusions drawn by it are not justified. Students went to the museum and art was discussed in a particular way, talking about symbols and analysis of paintings and so forth. Then the students who went to the museum and heard this, and those who didn were asked to write an essay about a painting. The ones who had been to the museum and heard people talking about paintings in the way the "good" essays were scored did better than those who had not been given exposure to an example of how people are expected to talk about art in an academic context. This is not a measure of critical thinking skills at all! It is a measure of who went to the museum and listened. To measure improvements in critical thinking skills, the content of the Air Max 1 Black Bonsai essay should not have been directly specifically linked Air Max 1 Flyknit Grey
