Click here for a post from Rebecca Loveless on “Word Bag Excitement” that offers teachers a sense of this excellent activity for studying word families modeled on Lyn Anderson’s work. This is a great reference for jumping in. Rebecca’s site has many more posts to explore too.
Click here for Mary Beth Steven’s brilliant recent post “Outer Beauty Attracts, but Inner Beauty Captivates.” This is a wonderful way to compare studying real “word families” compared to words that simply rhyme. Explore her whole blog!
Click here for an inspiring post, “Comprehending Spelling” from Sue Hegland’s excellent blog, “Learning About Spelling”. This is a short, accessible and eloquent case for why we should do the obvious -- teach our written word works.
Click here for this video on how morphological and etymological families work. This video is a collaboration between myself and Marie Foley. The video goes into many details about this topic that is so important for anyone teaching from an SWI frame.

Revised <sign> Lesson in “Teaching How the Written Word Works”
Books printed after May 2013 already include the revised lesson. You know you have the revised version if you see on <ify> suffix on the <sign> lesson on page 8. Even if you have the revised version, I recommend you download this pdf to gain from the explanation that helped me understand why this revision was needed.
Free SWI Digital Drop In Sessions Monday’s 5pm EST
I began offering this free weekly session at the beginning of the COVID pandemic in an effort to ensure teachers and parents had a place to pose questions about SWI whether or not they could afford to attend more formal on-line courses.
The response has been so rewarding (and fun) that I’ve only missed a handful Mondays since the first session on March 23rd, 2020. I plan to continue indefinitely even once we are past the pandemic.
There is no sign up, just a regular date and time to join. Most weeks we simply address questions people bring. Some weeks we have a special guest, or planned investigation to share. Every week has novices and experts who come to share their questions/experience, or just listen in.
Click THIIS LINK for a document reflecting on learning from the first session that is filled with links to free resources to build understanding of scientific word investigation.

•Shananan On Literacy points to Pete & Jeff Bowers re shift in thinking
-
Click HERE for the April 12 “Blast from the Past” post. In this post Tim Shanahan shares the post from 2017 in which he cited work from me and my brother Jeff. Even though we differed in our thinking about some key things, I was delighted at with his curiosity in our work, and took it as very constructive and positive exposure to it. However, Tim uses this ‘blast from the past’ to highlight to his substantial audience that given the research evidence since that point, he now is leaning more in the direction of our discussions back then and sees morphological instruction to be valuable earlier than he previously recommended. I so appreciate the modeling of following the science and publicly changing one’s thinking as a result.

Videos on Research & Practice
See this VIDEO (Bowers & Foley, 2025) on the ‘Nested Combinatorial Structure of English Orthography’ and how the matrix and word sum guide instruction fits that universal of oral and written language.
This video builds on David Share’s major new article “ Blueprint for a Universal Theory of Learning to Read: The Combinatorial Model. that is still in press, but accepted for publication by Reading Research Quarterly. The pre-print of that article is available HERE.
See this VIDEO ‘The Matrix Matters Because Language is Combinatorial’ (Bowers, 2025) was my presentation for the 9th Annual Dyslexia Virtual Conference of the Dyslexic Training Institute
This is the video I described as the ‘companion’ video I was working on in the video introducing this concept of language “combinatoriality” linked above.
This was my talk for the 9th Annual Dyslexia Virtual Conference which has just been made publicly available. This goes into much more detail on this important topic.

WW Newsletter #114:
Understanding what SWI is and what it is not (Feb, 2025)
Click HERE for the first WW Newsletter of 2025.
SWI has been receiving more attention in formal and informal research venues recently. In this newsletter I highlight ways in which this increased attention can foster misrepresentations of what SWI does and does not claim. I address some examples of common misrepresentations and misunderstandings presented in high profile spaces in the last couple of months.
I also point to an ever growing number of resources for SWI including a brand new one on Vocabulary & Morphology using SWI and a new video on tips on how to use the Real Spelling Tool Box 2 and much more.
Here are a couple of recent special publications about learning in my courses with many orthographic concepts and resources to support your learning.
