interventions and b) standing on a set of sustainability-thinkingskills. Data on these two outcomes of interest are gathered through the use of end ofsemester surveys as well as written reflection activities included in student projects.Student survey results are analyzed with descriptive statistics and thematic analysis foropen-ended items. Written reflections are scored with institute-developed rubrics tied toeach system-thinking skill, depending on the nature of a given reflection prompt.Initial results from thematic analysis of open-ended student survey items suggest thatafter experiencing the sustainability intervention, students exhibit an initial understandingof the three key components of sustainability: social, economic, and

One hundred and twenty (120) students completed the pre-test. Theresults for this are detailed in Table 4. As this test was administered during the first week ofsemester 1, it is valid to compare with the scores reported

respect to their everyday lives. This idea wasreinforced with the integration of reflection questions interspersed within the everyday usessection where students are encouraged to elaborate on their personal experiences with a specificconcept. Examining the topic of orthographic projection, the idea of using a glass box to containa fragile sample for viewing in a museum environment like the bird nest in Figure 2, wouldlikely be familiar to most students making it a relevant example to incorporate into the PBLM.Figure 2: Everyday uses example: bird nest for observation.A corresponding reflection question inquires about places the student may have seen somethingsimilar, such as sports memorabilia. This real-world example helps put into perspective

self-developed survey, followed by focus group interviewsof the students to reflect students’ attitudes toward classroom attendance and their learningefficacy under this innovative self-regulated learning. Three rounds of surveys wereconducted to examine students’ changes in attitude and preferences as well as theirperceptions of their learning efficiency. Based on students’ self-reports, the average rate ofphysical classroom attendance was 26%. More than 60% of the students preferred this“soft classroom” learning. In addition, they reported on how efficient this course was inresponse to this new learning environment. The results from the three rounds of surveysand focus group interview provided evidence of the success of the current case

of autism, and reflect on their care practices (Doğa, 2020). Over adecade's research has shown that computer-assisted technology can be used as an educationaland therapeutic tool in this population (Ploog, 2012). The design of the augmented and mixedreality environments in this study has been done to facilitate a simple learning experience.Another critical aspect that is closely interrelated to design is ‘cueing’. The role and importanceof visual, auditory, and tactile cueing in designing augmented environments has been highlightedby many notable works (Angelopoulos, 2018; Janssen, Steveninck, Salim, Bloem, Heida, &Wezel, 2020; Miller, Cooper, & Szoboszlay, 2019; Pangilinan, Lukas, & Mohan, 2019).

attainment of the learning outcomes, whichdo not explicitly reflect SV skills, and can thus not be used to quantify improvements inSV. A further challenge is the difference in the order of topic presentation that the twoexperienced instructors favor, thereby inhibiting the development and use of a formativeassessment method to quantify the impact of the individual pedagogic measures on thestudents SV skill development. There are a number of tools that have been developed to assess SV development,with perhaps the most widely used (in the US) being the Purdue Spatial VisualizationTest (PSVT 34), of which often only the rotations section is used (PSVT:R) 35. Sorby andGorska 4 and Study 24 present a comparative of a number of available tests

researchers observed that improving 3-Dvisualization leads to better performance in engineering graphics and in most other engineeringcoursework resulting in improved retention and graduation rates. The majority of the 3-Dvisualization exercises currently being used by students in Design and Graphics classes presentthe objects in isometric views already in 3-D, asking the viewer to create multiple views, foldpatterns, manipulate, reflect, or rotate them. Other exercises present the objects in incompletemulti-view projections and ask the students to add missing lines. The newly proposed methoduses a different approach. It uses the standard multi-view projections to show a number ofrectangular bricks arranged in various patterns. The viewer must count

. In DFM, a more functionally constrained project could accomplish the same thing.• Building the Connection between Function and GD&T This follows from the previous point and reflects the challenge noted earlier that students experience the greatest difficulty when they are required to come up with the correct controls, and more so specific values of tolerance that will result in a desired function. In industry, this experiential knowledge has been acquired over time and is captured in standards and procedures for dimensioning and tolerancing the specific products that are designed and manufactured. Though it is difficult to reproduce this in an academic setting, tooling design again represents a good application

Particularly, single factors were identified for two of themeasurement of improvement used: Raw and Tier, but multiple factors are needed for apredictive model using Percentage as improvement indicator. It is of interest as well that the one-factor models identify question that belong to the same subset, questions that require rotationabout at least two axes in order to have a correct answer. Thus reflecting the importance of suchexercises for spatial visualization skills.In terms of demographic parameters, the results indicate that they do not have a

Renovation or reconstruction would have different sequences, such asintegrating the old wall into the new wall. In addition, evidence of the key-in feature was onlyshown in eastern Jinshanling; this may or may not apply to all sections of the wall inJinshanling. If evidence is presented that the key-in was not used, the authors will update thedesign to reflect this.There was also an inaccuracy in Google Earth’s satellite images of the terrain and locationsof the Great Wall.

College during the fall of 2014 in the Incubator experience. Although the pilot study did notfind an advantage of teaching integrated courses, it was an important step towards the re-envisioning of the existing curriculum. The Purdue Polytechnic Incubator operated as a facultynetwork that explored best practices on education by deconstructing the models of traditionaldisciplines. This allowed for re-visioning of the traditional educational model by including co-teaching and group reflections as a core component of the experience. The integration ofhumanities and technology provided with a rich ground for student development. Rather thanfocusing only in a mechanistic approach to technology, students were able to draw parallels withtheir cultural

In the first-year engineering course, ENG1101, approximately five 1.5 hour classsessions are spent on sketching topics, followed by an exam. The graphics topics covered in thiscourse include isometric and oblique sketching, orthographic projections of normal, inclined, andcurved surfaces, rotations, reflections, and planes of symmetry. Students scoring 60% or belowon the PSVT paper and LMS versions were excluded from this analysis because they wererequired to
