The power of teachers sharing beliefs, practice, and data

That the Manaiakalani kaupapa works is hard to dispute. The data keeps accumulating: writing progress at twice national averages. As we also know, reading and maths less so (only 1.5x national averages).

Look at the fluency of writing from Jordan, of Year 7. The visual expression of Sofia in Year 10. The list goes on.

I tend to overthink things (too often) and often therefore wonder why this stuff works. I ask the question 'what is it about Leaner Create Share' that creates this acceleration? Is it the pedagogy itself, or is it the fact that we have a clear visible pedagogy that we promote, that is clear to all staff across the kura engaged with this Manaiakalani kaupapa? We should not assume that this is universally so. I have seen many (I suggest most?) schools that do not have a clear pedagogy, and far too many teachers who do not know what they stand for, nor how they will achieve it.

I settled on the view that it doesn't much matter, because it works, and that is the most important thing. I tend to use a phrase that a former colleague would often use, and I say of myself 'I'm not over bright, you know'. 

It was a comment by colleague Gary Roberts (Principal, Hornby Primary School) that generated another of those 'aha' moments for me as we talked about our Teacher Summits run across our Uru Mānuka kāhui ako. He said this is what Hattie calls 'Collective Teacher Efficacy'. Some will no doubt say 'what the ** is that?'

Easy:

The concept of Collective Teacher Efficacy itself is much older. It was introduced in the 1990s by Albert Bandura and is rooted in his concept of self-efficacy, Bandura (1993, 1997). He defines collective efficacy as “a group’s shared belief in the conjoint capabilities to organize and execute the courses of action required to produce given levels of attainment.” Bandura found that the positive effects of CTE on student academic performance more than outweigh the negative effects of low socioeconomic status.

In a video interview clip on the same page Hattie (https://visible-learning.org/2018/03/collective-teacher-efficacy-hattie/) makes the point that collective teacher efficacy is not only a matter of believing that students can achieve, that what we do makes a difference, but it is also a matter of backing it up with the data to show that it works. The 'effect size' of CTE is 1.57, the highest of any of the potential impacts that the Visible Learning team has investigated. As a point of reference the effect size of simply leaving learners to do their own thing is 0.2 i,e. that would be natural age related improvement.

We have the shared view of a consistent pedagogy, we are building this collective view that all learners are capable of being successful in their learning, we have the data to show that what we do works. We share practice across our kāhui ako, and across Manaiakalani's 100+ schools, practice that we have established works.

Collective Teacher Efficacy? Yup!!!
