Is there a way instead of using the word lessons to use or change to the word module, or any other word desired?

Have you tried Custom CSS? That usually will do the trick to sizing your website to mobile size.
See if this Changes the size of the word 'MirbooNorth' on the header on the mobile site. 
LET'S TEST THIS OUT, SHALL WE?
 
COPY AND PASTE BELOW CODE IN THE CUSTOM CSS UNDER DESIGN, IT'S WORTH A TRY🤷🏻‍♂️
 
/* CSS FOR TABLET AND MOBILE */
@mobile:  ~"only screen and (max-width: 640px)";
@tablet:  ~"only screen and (min-width: 641px) and (max-width: 980px)";
/* CSS FOR TABLET */
@media @tablet {
/* Insert Code for Tablet Below This Line*/
/* Insert Code for Tablet Above This Line */
}
/* CSS FOR MOBILE */
@media @mobile {
/* Insert Code for Mobile Below This Line  
 
/*MirbooNorth Header*/
#block-yui_3_17_2_1_1620831576334_3950{
max-width:50%!important;
margin: 0 auto;
}  
//* Insert Code for Mobile Above This Line *//
}
