Students need to have an understanding of or prior knowledge of what is going to be presented to them withing the classroom or the lesson will not be beneficial to them. In activating their prior knowledge, the students will make a connection and will be able to take the material presented to them with easy. 
The specific implications for instruction and assessment based on student individual differences and classroom characteristics would be if a student would need help with a specific learning area based on a disability that could affect the learning process.
Students learn in a variety of ways, they learn
visual which are learners who learn through seeing things in front of them. The second is kinesthetic and tactile which are learners who experience through doing things with their hands. The final is an auditory learner who learns best through hearing things said to them.
(ex. kinesthetic and tactile learning)
The understanding of student differences that may affect learning are: the student’s age, the student’s involvement in their learning, and their knowledge of the computers.
The characteristics of the classroom that may affect the learning would be the way the classroom is decorated and how students’ desks or tables are arranged within the classroom (ex. if the students desks are in a box formation may make some students feel uneasy and their minds wonder).
