The objective of this study was to determine if the way students were grouped affected their performance in the classroom. Many studies have focused on grouping or tracking students through various grades based on their ability, while this paper wanted to specifically see how it could affect their performance in a single mixed ability level high school science classroom. Students were separated by three different methods; alphabetical pairings, student choice, and high ability with low ability students; all groups were given the same instruction and observed to see any possible increase or decrease in student performance. Students were compared using their test scores and laboratory experiment reports.
