by performance goals focus more on the optics of lookingnot-smart or performing poorer than their peers. Research has shown that students’ goal orientationhas implications towards their academic performance [3]. Besides goal orientation, some researchershave proposed that the how students approach study reflects on their cognitive engagement withacademic material, and may affect their performance in school [3].The Students Approach to Learning (SAL) theory proposes two major levels of cognitive processesthat characterizes students approach to studying: surface-level strategy approach and deep-levelstrategies approach [4]. Surface approach to studying is associated with rote memorization and thereproduction of facts, without making any deep

Engineering undergraduates enrolled in physics and thermodynamics reported thefrequency of use of problem-solving strategies, confidence in their ability to solve problems, andanswered demographic questions. Measures of performance included course grades. Factor-analytic methods that were applied to students’ reports of strategy use identified three types ofstrategies, which were labeled Execution, Planning and Looking Back, and Low Confidence inAbility. The three factors were significant predictors of course performance, based on correlationand regression methods that were applied to the data. The study provides evidence that usingproblem-solving strategies improves

America’s Promise (LEAP) was able to identify many suchHIPs that are gaining attention [1]. In a subsequent report, Kuh found that students whoparticipated in these HIPs show that they were positively affected by these activities, asmeasured by the National Survey of Student Engagement (NSSE). It was found that these“deep approaches to learning are important because students who use these approaches tend toearn higher grades and retain, integrate, and transfer information at higher rates [2].” Thus,what we set out to do is to apply HIPs to a 300- level engineering course at a state collegelevel and gather data regarding its effectiveness, student reflections, and possible futureimprovements for better learning outcomes.HIPs in a Mechanical

With funding from an NSF IUSE/PFE Revolutionizing EngineeringDepartments (RED) grant, our School of Engineering is "revolutionizing" engineering education,with the aim of preparing students to innovate engineering solutions developed within acontextual framework that embeds humanitarian, sustainable and social justice approaches withtechnical engineering skills [1].

In all, a total of six half-hour long focus group interviews were utilized to facilitatecollective reflection and dialogue by providing students opportunities to openly discuss theirlearning experiences with fellow peers. The number of students participating in a given focusgroup ranged between 6-8 and all focus groups sessions were audio recorded for transcription andanalysis purposes. The dynamic nature of the focus group method stimulated conversation amongthe students and sparked conversations centered on their unique experiences related to the

Further, this reflective activityincreases both understanding and retention.The Seven C’s were introduced to students in several Mechanics of Materials classes during arecent multi-year study on assessment methods [1]. Though they were not a formal part of thestudy itself, it was observed that the C’s played a key role in student success.

An effort is made as part of this study to capture some of the long-term impacts of theefforts in the thermo-fluids lab course, through a survey of student perceptions of their abilitiesand experiences. The data included in this study was administered to seniors in a post-requisitethermo-fluids course asking them to reflect back on their technical writing skills and the coursesthat impacted such skills. This cohort of students had directly been impacted by the technicalwriting efforts described in this study, and hence could provide such insight

Reverse engineering is a process in which the starting point ofa new design starts with an existing design [1]. These tools were incorporated into a designcourse in a Mechanical Engineering program to design and validate a lighter version of abracket.3D Laser scanners are used to obtain the geometry of existing parts determining the position ofa scanned area by sensing the reflection of a laser on a surface taking into account the period ofreturn of the light ray and the angle of impact [2].

This is exactly a scale ofhow much progress the students have made based on the lesson they learned from the instructor.The instructor can use some rubrics to assess this directly. Some formal tests can be administered.Self-reflection and self-evaluation by students can be a significant part of evaluation. Revised andresubmitted statements of learnings of students can also provide some clues towards evaluationsof their learning outcomes.2.2 The DBR MethodAs mentioned earlier, the word DBR

At the end of the semester, the class votedon the best problem-solving partner, and that person received a small prize. This helped tohighlight what makes a good partner but was too late to affect student behavior. Another way toraise awareness of desirable partnering behavior may be to ask students in an out-of-class or in-class assignment to reflect on what makes a good partner and which behaviors they themselvesexhibit.Laboratory Activities The course made use of a large material testing load frame.

Thehomework solution template was designed to force students to utilize the problem-solving approach theinstructor was working to develop. For instance, students had to draw a diagram of the system, whichsometimes seems unnecessary to students early in the course because the problems are straightforward.However, forcing the student

However, many doodles were created last minute orwithout much thought in order to obtain the points.On the positive side, several students provided comments such as:I like the doodle because it helped visualize the concept.I liked the doodles because I felt they gave me an opportunity to think in more detail of the actualapplications of what I'm learning, other than the applications given to me in class.

Despite the improvement in DEW percentages,the rate of students achieving an A in the course was significantly higher in the mixed class thanin either the flipped or traditional sections. Overall, the grades reflected similar outcomes to theexams where students in the mixed section outperformed students in both the flipped andtraditional sections. This indicates that, despite some promise shown in the flipped coursesection, students in that section were still not able to achieve at the same level as their peers inthe mixed-delivery class.
