My 9 year old nephew was making a Powerpoint slideshow today. I watched him regularly saving his slideshow using the menu and asked why he was not using the Save button, to which he replied, “Which one is it?”.
I looked at the toolbar and saw a button with a picture of a floppy disk. I don’t think he has ever seen a floppy disk in his life. I’m not surprised he didn’t associate this button with saving his slideshow.
I’ve seen articles suggesting that buttons with icons are not good for new users. This is especially true if the icons reference old technology they have never encountered.
