Of course a students personality type can effect their ability to learn in certain situations. The simplest way around this is to offer a wide range of activities and alterations to the learning environment. A student who learns best on their own may find it more difficult in a group setting and others may do an activity in a group that was otherwise difficult for the student and the lesson will simply click for them just by changing their environment slightly. It is impossible to know the best learning environment for every student in your class so it is vital to offer a varied lesson plan to reach all students.
