Many people include too many jobs on their resumes that are irrelevant to their desired career path.  For example, while its important to show that you worked your way through college, its OK to consolidate those job experiences under your employment section in bullet form.
The interpersonal and problem solving skills you developed are probably more important to mention in this section, than all the specific duties in those positions.   Subsequently, use the space that you’ve saved, and add in more details about advanced coursework in your field of study, information about important projects, and ample description of career oriented internships.
