Unlike like hardcopy material, eBooks, theoretically, have the advantage that they may be more readily edited, updated, improved and expanded. But so far, you're lucky to find editions being updated yearly, and so you find content and topics become so rapidly unappealing, outdated &/ inaccurate. It goes without saying the eBooks save trees in the process (though it is questionable that they are actually more eco-friendly, but that's a matter for another time since electronic media is in). It is unquestionable, nevertheless, that the Virtual World is vital for education, especially in these times.
So my novel idea is to have published an eBook here and in the Cloud (currently with Evernote), which may be accessed for a one-time fee (of approx. €92 / USD $100), and members get access to continual updates, improvements, and additions weekly, sometimes daily for as long as you and I live. (More details on my EXTRAS page).
The content of my eBook is a unique compendium based on years of experience in ELT of having taught English to Foreign Language to adult learners. It includes what I believe to be an essential appendix to the syllabus for teachers of English as well as an insightful, original way for autonomous learners of English tired of the traditional and flawed contemporary methods to improve beyond the mediocre standard of today's globally used English.
The aim of the eBooks is to raise the level of pre-intermediate to upper-intermediate level non-native speakers of English.
I also offer unique English lessons online on Zoom that can help to assist with the eBook content. (See the offer in EXTRAS on my page).
