In a controlled experiment, presenting words in a small font leads to better memory recall than presenting words in larger font. when teachers adopt small font for class reading materials, however, there is no improvement in students’ recall. what does this study lack?

That a small font leads to better memory recall than presenting words in a larger font,it is only the scientific fact which is external validity.Students who are studying with concentration only able to recall the words in memory it not matters with any small or larger words. The words which are described with pictures can easily recall by students.So there will huge improvement in studies among students.

This is what i found on google “eightin 1997, the mccaughey septuplets were born in carlisle, iowa. multiple births of as many as eight babies have been born alive, the first set on record to the chukwu family in texas in 1998; one died and seven survived. in 2009, a second set, the suleman octuplets, were born in bellflower, california.” i was surprised about this . i don’t want to have that many babies .
