Hello, Kay.
Just to check, do you mean the stages in the cycle – Connect, Wonder, Investigate, Construct, Express, Reflect – or something more detailed?
The Empire State Information Fluency Continuum (ESIFC), which FOSIL is based on, is a model and continuum of skills that stretches from PK (Reception) to Grade 12 (Year 13), and has been in use in New York State – more than 3.2 million children in 4,236 schools – since 2012 (or 2009 in New York City – the ESIFC is also in use in at least British Columbia and Rhode Island).
We have experienced no problems using FOSIL with our Year 6 students, and I can’t imagine why this would not be the case lower down, although the challenge would be developing age-appropriate graphic organisers to support the development of the relevant inquiry skills – something that we would be very interested in helping with.
In addition to the graphic organisers that we have developed (Resources), see also the ESIFC Assessments by Grade and/ or Standard, which is where I first started.
