Great read / especially for my immersion families.
Open study -- Sprouts of literacy: The longitudinal prediction of early morphological awareness skills in French -- from Swiss and French researchers, investigation into the benefits of teaching morphology, and students using morphology, in the earliest grades.
French morphology instruction and knowledge matters even in G1, especially to be able to retain and accurately recall French word spelling. From the study's conclusion:
"Morphological awareness assessed at time 1 predicts general reading and spelling skills a year later in French-speaking children followed from Grades 1 to 2 and from Grades 2 to 3.
Morphological awareness skills can thus be considered a cornerstone of literacy acquisition. In languages like French, given the number of morphologically derived words that children encounter during their schooling, morphological awareness should not be overlooked and should be widely taught and practiced, promoting literacy development."
Link to the open study is in a comment below.

"... the aim of the current study is to test the early contribution of derivational morphological awareness on literacy skills (reading fluency and word spelling) and, more specifically, to assess whether this effect is present on morphologically derived words (in reading and spelling) but also on more general measures of reading and spelling. To do this, we recruited two groups of children that we longitudinally followed: a first sample followed from Grade 1 to Grade 2 and a second sample followed from Grade 2 to Grade 3."

"Morphological decoding—defined as the use of morphemic units to read or spell complex words—is particularly relevant in the early stages of literacy acquisition, as it allows learners to process larger orthographic units beyond grapheme–phoneme correspondences. This mechanism is therefore central to the present study."

"... in a longitudinal study conducted from the beginning to the end of 2nd grade, Desrochers et al. (2018) compared the contribution of morphological awareness to various measures of literacy in English (opaque orthography), French (consistent orthography in reading and inconsistent in spelling), and Greek (transparent orthography).
The results showed that morphological awareness was a unique predictor, after controlling for phonological awareness and rapid automatized naming, of (1) reading comprehension in the three languages, (2) reading fluency in French and English, and (3) reading accuracy in English.
Moreover, in languages with a rather consistent orthographic system for reading (such as French or Italian), it seems that morphological awareness has a role to play in young or struggling readers, particularly in terms of reading fluency. In sum, while knowledge of grapheme–phoneme correspondences is sufficient for reading accuracy in consistent orthographic systems, morphology plays a role in accelerating reading fluency."

"Although reading and spelling are closely related, they differ in key cognitive demands, as spelling requires active production, including working memory and letter retrieval, whereas reading mainly involves recognition."

"... Casalis et al. (2011), in a study with French-speaking children in Grades 3 and 4, showed that morphological awareness predicted not only the spelling of derived words but also general standardized measures of spelling. As for the longitudinal studies that have been conducted, they provide evidence of the predictive relationship of morphological awareness for later spelling skills (Deacon et al., 2009; Desrochers et al., 2018; Manolitsis et al., 2019)"
--
"Our main results show a unique contribution of morphological awareness to standardized text reading fluency, on word spelling, together with an effect on morphologically derived words during spelling only."
--
"While the importance of phonological skills in literacy acquisition is already well established, our study further supports this finding and suggests phonological awareness plays an equally important role at this age in both cohorts in reading but becomes more important in word spelling in the G2–G3 sample..."
--
"These results seem to be in line with those found in languages with a transparent orthographic system, where morphological awareness is a predictor of reading fluency (Burani et al., 2008; Desrochers et al., 2018; Giazitzidou & Padeliadu, 2022; Marcolini et al., 2011). French-speaking children therefore use their morphological awareness, in addition to other components such as phonological skills, for reading texts, after only one to two years of formal literacy learning."

For spelling, our results show a dual contribution of morphological awareness: one to standardized word spelling, and another to morphologically derived words in spelling.
The longitudinal contribution of morphological awareness to word spelling skills, assessed by a standardized test, had already been shown by several authors (Deacon et al., 2009; Manolitsis et al., 2019), but only in one study with French-speaking children (Desrochers et al., 2018). One explanation for this finding could be that children use their knowledge of morphology to spell the words in the word spelling task that are for the most part (9 out of 10 words) base words, thus allowing for the formation of other words of the same family (even if they are monomorphemic words). For example, the word *ville [city] has many morphological derivatives: village and *villageois [villager]. If children use their knowledge of derived words, they will be able to write a related word of the same family.
To our knowledge, no study has reported the contribution of morphological awareness to morphologically derived words in spelling among children, moreover, in the earliest stage of spelling acquisition.
Our statistical model showed that this relation, between morphological awareness assessed in the first year and morphological decoding in spelling assessed in the following year, is significant in both samples.
This effect was one of the most expected, especially since it was consistent with the Morphological Pathways Framework (Levesque et al., 2021) that hypothesizes that morphological awareness plays a role in the spelling of multimorphemic words. In other words, children use their knowledge of morphemes to spell these words.
Since the French writing system is particularly inconsistent in spelling (Ziegler et al., 1996), children need to use their morphological awareness in addition to phonological information to spell more accurately, because morphemes are islands of regularity among the majority of irregularities"

"The contribution of morphological awareness to general reading fluency and word spelling shows the same pattern of effect size across groups: a stronger effect in the younger group (G1–G2) compared to the second group (G2–G3) based on the non-overlap of confidence intervals. This pattern is contrary to our hypothesis."
--
"One of the most important limitations of our study lies in the measures we used to build our model. Indeed, morphologically derived words are a latent variable for reading and spelling, while the “general” measures of spelling and reading are only represented by manifest variables. It would have been interesting to compare latent variables on the same level.
Also, we were not able to directly compare reading and spelling performance because we measured reading using a text reading task (to measure fluency), whereas we tested spelling via the dictation of single words."
