Thanks for your interests in my videos. I don't have videos that explain specific research in detail. My lecture videos are for an undergraduate course, so they are broad in coverage but not too deep.
I believe the “i” and “i+ 1” come from programming/math and stands for “iteration”. If you have a sequence of numbers (1,3 ,6… etc), “i” is a symbol that represents the position of a number in that sequence. So i=1 would be 1, i=2 would be 3 , i=3 would be 6 and so on (assuming we start counting at 1 and not at 0) As a metaphor i then represents any language learning level, while i+1 is the next iteration in language learning. Basically “i” is your current level and i +1 is the very next step. I presume the importance of this is that if input is perfectly at your level (100% comprehensible, 100% repetition) there is nothing new to learn? While i+1 is input that is slightly above your level, but is still comprehensible enough to understand?
@@Gabu_Dono That also makes sense. Thank you. As I wrote, I couldn’t find the original reference where Dr. Krashen himself explains where it came from. If I come across the reference, I’ll share it here or somewhere else.
Thank you so much for valuable information 😊
Thank you for this informative video. I am able to understand what is input by watching this video.
Glad to hear that the video helped
Thank you so much
your videos are great please keep uploading more videos about SlA. What about research do you have any videos about research in SlA?

please what does «i» stand for
It seems that "i" in "i + 1" stands for the learner's interlanguage, although I don't know the original reference.
