In this case itwould be possible for the evaluation instrument to measure static student beliefs more thanpeer’s performance. However if responses change significantly over the duration of the capstonecourse then some change to goal structures is occurring. While not providing a definitiveevaluation tool, this work can potentially lead to methods to gauge changes to an individual’sability to function of a team. Judging student efficacy on a team is also addressed by the fourthquestion.

Theundeniable benefit of podcasting is its ability to allow students to pause a class for reflection orto replay portions of a class for review.IntroductionFor some time now, technology-enabled teaching methods (e.g., distance learning, virtual/remotelaboratories, podcasting, and on-line, hybrid or blended courses) have promised greaterefficiencies for education delivery and improved student access, and is purported to better matchthe learning style and preference of today’s students. Few scientifically rigorous studies havebeen conducted to test the effectiveness of these methods because, most likely, the methods areevolving at a rapid pace as the

In most implementations, these final presentations are also assessed, often forcommunication, to decouple the success of the physical prototype from the presentation andcourse grade. In several implementations, students have also completed some preparatory workin advance, and reflections on their experience afterwards. See Appendix A for full schedules ofMech, Tron, and ECE Days.While many of the Engineering Design Days implementations have some competitive aspect, theprizes are often merely bragging rights.

motivational goals for learning with respect to course favoritism are reflective of a statedependence rather than a trait the students hold with respect to the way they approach learning.Thus, motivational goals of engineering students are likely to shift, some substantially, based ontheir affinity for a course. The implications for our findings are such that if students favor acourse they are more likely to engage in learning at the mastery level and seek deeperunderstanding and develop more complex knowledge of subjects based on intrinsic factors. Incontrast, if students disfavor a course they are likely to be driven by external factors, like grades,or simply passing and getting through, and are much less likely to develop and retain deep

The D3EM program serves asan example of how impactful programs can be designed to encourage students to explore avariety of potential future career pathways, particularly beyond tenure-track faculty positions.Implications from the findings include the continued implementation of such programs andsustained efforts to change the conversation about PhD careers that reflect the job market andgraduate student interests.Introduction In the past decade, graduate engineering education has emerged as a research

What are the differences in preparednessbetween the two domain specific student groups? Which elements of student profiles best predictglobal preparedness within and across the two student groups? In designing both the engineering global preparedness index (EGPI) and the businessglobal preparedness index (BGPI), similar subscales of the previously described generic globalcitizenry instrument were utilized as these subscales have been closely aligned to global theory.To make the instrument domain/field specific, the individual survey items were altered withinthe subscales to reflect

These situations, when added tothe fact that the course requires the use of mental processes that are generally complex andrequire creativity, ingenuity, and discipline, can cause a high desertion rate and a low retentionrate. This is, consequently, reflected in the low passing rate, which is currently about 35%.Second, the teaching method being implemented by many faculty has lost sight of the fact

Leah Jamisen, Dean of Purdue'scollege of engineering, also calls for "reflection,"3 a critical practice of moral and ethicaldevelopment4. While many of these skills have appeared to some extent in engineeringaccreditation criteria, engineering programs traditionally focus on the science andengineering content in their curricula, rather than developing and measuring skills like“life-long learning”. In an effort to intentionally strengthen students’ development inthese other areas, we turned to the research literature to discern how the variousconstructs such as moral development or self-directed learning, are linked to controllableaspects of the learning environment

LML differs from learning styles approaches in thatlearning styles typically identify the learner with a personality type or category rather than aprofile reflecting degree of preference for multiple interacting patterns. Another key difference Page 13.1345.2is that LML emphasizes the learner’s capacity to use his/her patterns consciously andstrategically to adapt to different learning expectations, rather than merely seeking

Narrowed focus and heightened involvement parallel a “flowstate”. The variables effecting immersion, engagement and flow were investigated by Hamari etal. in the context of educational game design [7]. They found that games which are challengingcompared to the skill level of the player led to increased engagement and immersion, inagreement with Flow theory.In their systematic review of game-based learning, Bodnar et al. found that of 191 papersconsidered, 54 included a measurement of emotional

Since trained observers who arenot involved parties in the classroom (i.e., neither students nor instructors) are conducting ourobservations, we have had to continually reflect on the precise detection, perception, recognition,and judgment of certain events to ensure our observations are accurately capturing what isoccurring in the classroom. This experience is much different than training observers to obtaininter-rater agreement, used often by researchers to ensure that observations are reliable acrossmany different observers. Instead, we have examined ways in which we can confirm the eventswe are recording are a valid depiction of classroom behaviors.In this paper
