Correlating Freshman Engineers’ Performance in a General Chemistry Course to Their Use of Supplemental InstructionAbstractThis study examines the correlation between first year engineering students’ use of supplementalinstruction and their performance in a required general chemistry course. Supplementalinstruction includes one-on-one and group peer tutoring, review sessions outside of scheduledclass time, instructor/TA office hours, and student-initiated study groups. Previous research hasshown that supplemental instruction is positively correlated with measurable factors such ashigher grade point averages and timely graduation rates, as well as less-easily measured factorssuch as long-term retention of course material, teamwork, communication skills, informationprocessing skills, and motivation. Last year, a study done at _________ University examinedwhat grade level triggered students to seek out supplemental instruction and what factorsaffected whether a student uses a form of supplemental instruction. This present study focuseson comparing course grades between students who do and do not use different forms ofsupplemental instruction and correlating these outcomes with factors deterring students fromthese resources.In order to understand a student’s pre-disposition and ultimate choice to participate insupplemental instruction as well as determine correlations with grade distribution, students in arequired general chemistry course were given pre-surveys at the beginning and post-surveys atend of the semester. Overall, 408 first year engineering students participated (a response rate of83%), including 332 non-honors students (26% female) and 76 honors students (45% female).Previous experiences have suggested that honors students would make less use of supplementalinstruction and on average have higher grades than the non-honors students.One focus of the pre-survey was on identifying a student’s predisposed “trigger point” at whichs/he decides to seek extra help entering college. In this current survey, females had a highertrigger threshold of A/B compared to B/C for males, similar to previous results. The availabilityof data for different types of course assessments, including exams, homework, and classparticipation, now has enabled correlation among individual trigger points, grades, and the use ofdifferent forms of supplemental instruction. Other factors assessed included whether a studentparticipated in pre-college preparatory programs (such as a summer bridge). This study alsoinvestigated how important convenience factors, such as time, frequency, and location of extrahelp, and incentive factors, such as food or friends attending a resource, are to students in theirdecision to use supplemental instruction. In both previous and the current surveys students haverated convenience factors as most important. This year’s study furthered this analysis todetermine what factors deter students from using specific resources for supplemental instructionas well as the impact of taking part in activities viewed as detrimental for course success, such asusing cell phones or laptops for activities unrelated to a class, sleeping in the classroom, orskipping class.This paper presents the survey results, methodology used, conclusions, and recommendations forincreasing first year engineering student usage of supplemental instruction.
