, we describe future research plans, which includeusing unsupervised machine learning techniques to move beyond basic binary classification.1. IntroductionIn this paper, we explore the process for training two supervised machine learning classificationalgorithms to classify student code comments as sufficient or insufficient using MultinomialNaive Bayes Classifier and a Random Forest Classifier. We are classifying comments fromstudent lab submissions as part of a larger NSF funded writing-to-learn to program project inwhich we are developing a framework for allowing students to self-monitor and self-assess theirown metacognition [1,2]. Students are provided with an Integrated Development Environment(IDE) that allows the students to use
stated goal that PYroMat can enablestudent exploration in the classroom. Generalizability of survey results was limited by a smallsample size, so further research may be warranted to further validate these results. From a facultyperspective, we are hopeful about the potential of this tool to continue to facilitate exploration ofthermodynamic properties by students, and to expand the range of assignment types that canfeasibly be implemented by students.Several key areas of further work are planned to improve the quality of the both the PYroMatbackend and the web interface: • Standardize the property access interface (in the Python backend) across both multiphase substances and ideal gases. • Improve the numerical convergence of the
. The purpose of this activity is to get the students thinking aboutthe relationship between a design on paper and the restriction of what is possible to build in thefield. Furthermore, this planning activity was meant to enhance the students’ reflective learningexperience after they run into trouble when they built their piece in the next activity. [Figure 3] Design Critique Session (Left); Idea Sketch Exercise (Right)3.2 Build Activity DetailsThe build activity was scheduled in two sessions: the first taking up the remainder of the firstday, and the second during the morning of the second day. Students were instructed to finishtheir molds by the first day so that plaster could be poured immediately the following day.Students
could serve as both aflashlight and a bottle opener. In order to successfully complete the project, students had toconstruct a virtual prototype in CAD, present their design ideas to a “customer,” construct aprocess plan using both an NC mill and an NC lathe, select tooling and process parameters,fabricate components, and finally, assemble and debug their prototypes.Table 1: Course content for the pre-2017, 2017, and 2018 versions of ET 349.

With the growth of makerspaces on universitycampuses, some efforts have been made to develop and implement some best practices toestablish new facilities [21] and to create a classification system of academic makerspaces as ameans to compare different makerspaces for planning purposes [27].The tools and equipment available, along with the design and layout of each makerspace, candepend on the community it serves. One of the most common features of any makerspace is theuse of digital tools for the creation of physical artifacts [2], [3], [6], [9], [25]. Along with 3Dprinters, many maker workshops include other rapid prototyping tools that can be used onmaterial like wood, metal and plastics, such as computer
approach basically involves the observation of aphenomenon, the description and measurement of its characteristics in a variety of conditions,the recognition of patterns of data, and the constitution of these patterns in theory (Reynolds,1971). The fasificationist or theory-then-research approach, on the other hand, involves thenotion of a conjecture or hypothesis to be refuted or falsified via the design of a research plan totest it (Chalmers, 1982). In this paper, we would like to emphasize that, whichever approach istaken in the process of building theory, there are elements and procedures in common that needto be identified. Dubin (1978) recognizes the following elements in theory building:Table 1. Elements in Theory Building (source: Chalmers
; (b) requiring groups tocomplete a project planning phase that serves as a roadmap for their experience; (c) encouragingassignment of tasks to individuals rather than condoning ‘group work’; (d) conducting regularcheckups of team progress; and (e) coaching teams or team leaders in dealing with non-performing team members or other team dysfunction. All of these aspects of team guidance bythe instructor are deemed critically important to project success [2, 6].Approach to Capstone Design ExperienceThe project groups or teams for the capstone design in chemical engineering at TAMUK areformed in the fall, at the beginning of the two-semester senior design course sequence (fall-spring sequence, also known as Design II and Design III). The students

We will also use their narratives to understand howto foster an innovative mindset in the engineering classroom. These findings will inform theeducational plan to develop an inclusive pedagogy to support latently diverse students.Impact of the Proposed WorkThis work impacts the engineering education community by 1) identifying alternativeapproaches to understand how to support latently diverse students, 2) employing a new statisticalmethod used for complex datasets, and 3) highlight narratives of latently diverse students tounderstand how they develop their
network analysis along with studentdemographics (both expressive and latent diversity [24]) to understand how diversity isintegrated into the social structure. Through this line of inquiry, we hope to identify which, ifany, student demographics are predictors of social activity. While this alone would be asignificant contribution to an expansion of the use of social network analysis within engineeringeducation, we plan on combining the social network data with students’ attitudinal profiles toexplore if their attitudes about diversity predict their social activity. This first step will lead to adeeper understanding of what diversity characteristics, either expressive or latent, work to predictsocial activity within an engineering

We also Figure 2. Examples of LEGO scenes.observed that students made changes to theirscenes and often noted these on their cards. However, we found that it still was difficult to fullyinterpret the scene and notecard, especially when students did not record a video description.

Admittedly, there waslittle opportunity for students to conduct mathematical analysis during engineering activities.More detailed analysis of the quantitative data is planned in which comparisons between groupswill be investigated to see if differences between the camps exist.Table 1: Results of Significant Survey Items Pre-test Survey Posttest Survey Survey Item Mean SE SD Mean SE SD I know I can do well 4.21 .118 .806 4.49 .109 .748 in science.

The first author conducted three interviews withVanessa and five with Dani, using the same protocol each time. Each interview began with theteacher describing her most recent units, often with pictures of student work and binders oflesson plans. The second part of each interview asked teachers to explain their instructional andpedagogical choices, reflect on why they persisted in teaching

But program funders and host universitiestypically want to see more than that, such as entry into STEM majors or recruitment to theuniversity. This study captures our effort to track long term outcomes of a program that’s beenrunning at WPI for the

Once a young woman was selected by her faculty advisor as a mentor because she was female. She told the mentee that she didn’t like the field—that her parents made her do it. That faculty member offered that mentor again and we declined.Mentor support before and during the program is important to gauge their interest, to help them think through how they are going to teach a high school student with much less specific knowledge than them—learn how to do what they are planning for students to do and also to see if they need any cultural competency guidance. During the program it is

Additionally, theproject provided students with an opportunity to practice their public speaking and presentationskills through the ‘poster session,’ an important aspect of their growth as a STEM engineeringgraduate.In the future, the instructors plan to explore pathways to have the material’s project centeredaround a societal cause (such as a local community-driven social project) or an actual case-studyproblem in collaboration with the local materials and manufacturing industries. The motivationbehind this approach is to give students a project assignment that will help the community

Results show a significant reduction in the advising session duration and general satisfaction from both faculty and students. The study is still ongoing. The next steps involve standardization and validation. We plan to standardize the process by reflecting and rectifying problems that aroused during Fall 2018. Some problems included miscommunication between PMs and faculty and delays in obtaining the executive summaries. We would like to expand the use of the new advising process to including all advising faulty and all first-year students in Fall 2019. The validation/post-implementation phase is conducted

We describe both methods below in order to compare them with thenewly-developed method, which we denote the projection method.This work is a part of ongoing research to establish the most effective method for teachingfourbar linkage analysis to engineering students. Previous related work has established thecomputational efficiency of deriving the solution for fourbar mechanisms using the projectionmethod [11].

A major goal of thisprogram has been to increase interest and diversity in STEM by giving students hands-onexperience in these fields. This paper will discuss the growing interest for such a program alongwith future plans. Additionally, this paper presents data from 2017 program participantsincluding an update of their education/career plans.Introduction:With the continued growth in STEM

Its capacity and capabilityincrease significantly over the years and a device can easily incorporate an advanced embeddedsystem. The FPGA based system introduces a new dimension – the hardware programmability– in the design process and the availability of the devices makes the hardware-software codesignparadigm more relevant and accessible. It allows a designer to explore both software andhardware to obtain optimal efficiency and performance. It will be an important paradigm forfuture development. Intel (the largest manufacturer of processors) recently acquired Altera (thesecond largest manufacturer of FPGA devices) and had discussed plans to integrate the
study, students near the end of their BME undergraduateeducation are less likely to perceive BME in terms of its potential impact on society. This may bedue to an increased awareness of how the student as an individual will be asked to contribute tothe field as he or she nears graduation. Students within the degree program also appear to have agreater appreciation for BME as an interdisciplinary field with medicine and biology being thetwo most commonly included non-engineering disciplines. Finally, asking students to perform adesign-related task as part of their coursework may encourage the perception of BME in terms ofdevelopment or creation of new devices or processes.

He discussed that his brother was in medical school and planning to do DoctorsWithout Borders and: …engineers have the same thing, Engineers Without Borders. So that's why I'm taking Spanish.

cultural transformations in many engineering programs. We posit thatthese three issues that are wicked problems. Wicked problems are ambiguous, interrelated andrequire complex problem-scoping and solutions that are not amenable with traditional and linearstrategic planning and problem-solving orientations [2].As design thinking provides an approach to solve complex problems that occur in organizationalcultures [3], we argue that these wicked problems of engineering education cultures might bebest understood and resolved through design thinking. As Elsbach and Stigliani contend, “theeffective use of design thinking tools in organizations had a profound effect on organizationalculture” [3, p. 2279].However, not all organizational cultures support
