          ABSTRACT: Industrial firms dependent on their developed engineering knowledge base lament
          the loss of years of accumulated capability as Baby Boom generation engineers fade into retirement.
          Looking for ways to retain this institutional learning, the notion of knowledge transfer between
          engineers of differing generations offers an opportunity to maintain competitive positioning and
          innovation momentum. Understanding how communication behaviours and preferences differ
          among the engineering disciplines and generations may be a key toward supporting corporate
          knowledge transfer. This exploratory study compares communication norms across disciplines of
          nearly 400 practicing engineers in America, seeking to identify similarities and differences. The
          study examines responses to a communications focused survey instrument using analysis of variance
          (ANOVA) statistical methods, offering a glimpse into engineering communication preferences
          and behaviours. Findings reveal that statistical differences relating to communication do not
          exist between the ten examined engineering disciplines, however, further inquiry and instrument
          development is suggested.

                                Diana Bairaktarova is a PhD Candidate in the School of Engineering Education
                                at Purdue University. She holds BS and MS degrees in Mechanical Engineering
                                from Technical University in Sofia, Bulgaria, and an MBA degree from the
                                Hamline School of Business, St Paul, Minnesota. Diana has over a decade of
                                experience working as a design engineer. Her graduate research is focused on
                                human learning and engineering, ie. understanding how individual differences
                                and aptitudes affect interaction with mechanical objects in engineering education
                                instruction, and how engineering students’ personality traits influence ethical
                                decision-making process in the engineering design. Diana has contributed to
                                manuscripts in the European Journal of Engineering Education, Children, Youth,
                                and Environments, and Contemporary Perspectives on Science and Technology in
                                Early Childhood Education, and published conference proceedings at American
                                Society of Engineering Education (ASEE), the European Society of Engineering

                                DEMETRA EVANGELOU

                                Dr Demetra Evangelou is an Assistant Professor in the School of Engineering
                                Education at Purdue University. She obtained her BA in Psychology from
                                Northeastern Illinois University, and a MEd and PhD in Education from the
                                University of Illinois at Urbana-Champaign. Demetra was awarded an NSF
                                CAREER grant in 2009 and a Presidential Early Career Award for Scientists
                                and Engineers (PECASE) in 2011. Demetra’s current research focuses on
                                developmental engineering, early childhood antecedents of engineering
                                thinking, developmental factors in engineering pedagogy, technological literacy
                                and human-artefact interactions.
