The items of the instrument gauged student perception of theirdevelopment of competencies related to understanding requirements, teamwork competencefrom an individual and team manner, communication, and understanding the design process. Theauthentic design problem that the students addressed in the class required them to use concepts,knowledge, and tools that they have been introduced to during their previous six semesters.In this paper we investigate the following competencies (Table 3): (A) Understandingrequirements of a project (B) Managing a team (team) (C) Managing a team (individual) (D)Communication (E) Understanding design

For example,positive emotions (e.g., joy) may increase engagement and nurture creative learning strategies,while negative emotions (e.g., boredom) may have an opposite effect, diminishing engagementand supporting superficial cognitive processing [2]. In other instances, negative emotions (e.g.,anger) may increase an individual’s desire to prevent future failure [2] and serve to improveperformance.Multi-componential measure of academic emotionsTraditionally, academic emotions are measured with self-reports [9], [10].

with a passing grade of“A”, “B” or “C” and receives grades of “D,” “F,”or “W” (withdraw). There are several possibleexplanations for the higher rate of DFW in spring 2007. The lower passing rate might be theresult of a small sample size or simply a pool of unmotivated students. For this course theinstructor offered recitation sessions, but few students took advantage of attending the recitationsessions or contacting the instructor for help in solving homework assignments. A goodprobable reason was that many students had access to the solution manual, and did not find itnecessary to seek instructor’s help for solving textbook homework assignments. We believe themain reason for poor performance by many students was that they had access to the
