Students' preconception due to former students' feedback about the difficulty of an undergraduate engineering course

Purpose - Most university students, if not all, develop a preconception about any academic course before taking it. This preconception undeniably affects students' performance by influencing their motivation. As a result, learning can be minimized. The purpose of this paper is to investigate the evolution of students' preconception about the difficulty of an engineering course - taught by the same instructor - for a period of seven semesters by analyzing the results of survey questionnaire completed at the beginning of every semester. This approach allows the instructor to assess students' preconception that is built by former students' feedback and hence control the impact on students' motivation which influences their learning performance. Design/methodology/approach - By analyzing the surveys' results, the instructor gets a close idea about how the course is perceived. When students harbor misconceptions that constitute difficult barriers to learning, it becomes necessary to take action like adjusting the way of teaching the corresponding course's content, or ultimately changing the course instructor for a couple of semesters. Findings - The adopted survey-based strategy implicitly helps the instructor to correct inaccurate preconceptions before they become crystallized misconceptions, while in case of a very positive preconception, one can continue to enhance the course level with even more challenging evaluations (e.g. exams). However, in case of a persistent misconception, a midterm survey would further help the instructor to better adjust the way the course is taught by objectively considering the obtained inputs from a considered C/D/S set (i.e. continue doing what was helpful/do start doing what would be beneficial/stop doing what is not working). Originality/value - To the best of the author's knowledge, no study has investigated the evolution of - or at least - students' preconception built by former students' feedback about the difficulty of a course despite its direct influence on students' motivation and hence on students' performance, thus filling an important gap in the literature. Indeed, one general positive aspect of students' preconception research is the attention it has brought regarding the absolute necessity for teachers and researchers to be well grounded in both content knowledge and pedagogical content knowledge.
