The Impact of Social Integration on First Time in College Engineering Students Persistence, Longitudinal, Interinstitutional Database Analysis. Persistence of engineering students was 51.5% from 1987 to 2010, based on a largemulti-institution dataset. Many approaches have been proposed to assess factors affectingpersistence. The main models on persistence are Tinto’s Theory of Student Departure, Astin’sTheory of Involvement in Higher Education and Pascarella’s General Model for AssessingChange. Tinto proposed that academic and social integration reinforce students’ commitment totheir institution and educational goals. Sociometric techniques from Social Network Theory arebeing adapted to develop measures of social integration among undergraduate students using alarge, multi-institution longitudinal dataset. This paper will introduce this approach and, inparticular, discuss the social network parameter “mutuality” and study its relationship topersistence in engineering. Mutuality is an index that assesses the tendency for individuals in agroup to reciprocate choices more frequently than would occur by chance. Subsets of students with the same major and starting years were sampled by institution.Unique institution-class-course identity codes were defined for section groups to establish whichstudents took classes in each other’s presence, and the mutuality index was evaluated for eachstudent cohort in a section group. Mutuality reflects reciprocity beyond random grouping, due tostudents having free selection of groups. A matrix of section groups and cohorts was built as abridge data structure to assess mutuality. A simplified mutuality algorithm was evaluated pereach cell in the matrix. A linear model for mutuality as predictor and persistence rate per cohortas the response was fit to subsets results. Two institutions with persistence rates of 73% and 44% were compared. Mutuality rateper group was p 0.73 2.26% and p 0.44 0.79% , respectively. Results suggest mutuality maybe related with persistence. Results for other institutions and subpopulations will be consideredin the final paper.Mutuality Distributions for Mechanical Engineers at two institutions. Institution A: Persistence rate 73%. Institution B: Persistence rate 44%.
