Consequently, IoT provides an opportunity to demonstrate the pervasiveness and social relevance of computing. Moreover, today's hobbyist- oriented IoT platforms empower entry-level students to create meaningful, real-world IoT applications. This allows rich computer science topics, such as event driven programming, concurrency, networking, information representation, cloud computing, etc., to be introduced earlier in the curriculum. Most importantly, IoT examples provide a compelling context for students to hone their critical thinking skills while solving engaging, real-world problems. Faculty interested in including IoT topics face several challenges: selecting a suitable set of topics, identifying an appropriate pedagogical approach, and, perhaps most daunting, choosing a cost-effective platform that lends itself to classroom use. This workshop will introduce the basic terms and technologies in IoT, discuss issues that arise when including IoT topics in classes, compare and contrast the most popular platforms for IoT, and walk participants through several classroom-tested, hands-on examples using a classroom-friendly platform (Particle's Photon) where they create both Wi-Fi-based IoT devices and corresponding web apps. Participants will need a laptop (any OS) with Internet access.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123615544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasingly, evidence suggests that we need to approach student perceptions of computer science and self perceptions of \"who does computer science\" before college, at ages in which students have not yet formed difficult-to-change viewpoints. In an effort to address underrepresented groups in computing, as well as to change common, stereotypical perceptions of what a computer scientist is, we ran a pilot summer camp that drew students from our local community and sought to increase their self-efficacy and change the way they conceptualized Computer Science. In designing the course, we leveraged approaches that have shown success at the college level - particularly Computing for Social Good and Media Computation - to introduce students to important concepts. The camp was structured as a week-long, full-day camp in one of the Computer Science department's computer-equipped classrooms, We taught programming in Processing to 28 rising 5th-9th grade students, focusing on artistic aspects and real-world inspiration. In this paper, we report on the project (both successes and failures) and the effects the project had on students' self-efficacy and attitudes towards computer science. We also provide some recommendations for others planning to offer similar camps.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124249265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They provide an ideal framework for abstracting relationships between related parameters. In image processing, tensors can be used to represent gradient information. The 2D structure tensor is one such representation, useful in corner detection and non- photorealistic rendering. This abstract summarizes my image processing filter based on the 2D structure tensor that generates artistic abstraction from photographs. With the 2D structure tensor, I explored ways to present the gradient directions of an image as artwork and investigated the relationship between the Gabor filter and the eigenvectors of the 2D structure tensor. Using this filter, I produce images that consist of a dense patchwork of lines, somewhat resembling certain artistic types of pen shading such as hatching and cross-contour shading. By applying this filter, I have found ways to categorize images that display salient groups of parallel lines. These images present a higher artistic quality and display better compositional style after being processed using the 2D structure tensor than the average photograph. Another finding is that not all resolutions of images are ideal for structure tensor processing and that an image size of 700-1000 pixels per side yields the best results from both a mathematical and artistic standpoint.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125379702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent work has suggested that machine learning approaches applied to snapshots of small programming exercises may be an effective solution to this problem. However, these results have been obtained using data from a single institution, and prior work using features extracted from student code has been highly sensitive to differences in context. This work provides two contributions: first, a partial reproduction of previously published results, but in a different context, and second, an exploration of the efficacy of neural networks in solving this problem. Our findings confirm the importance of two features (the number of steps required to solve a problem and the correctness of key problems), indicate that machine learning techniques are relatively stable across contexts (both across terms in a single course and across courses), and suggest that neural network based approaches are as effective as the best Bayesian and decision tree methods. Furthermore, neural networks can be tuned to be reliably pessimistic, so they may serve a complementary role in solving the problem of identifying students who need assistance.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129826865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is imperative that students are familiar with accessible practices to support this often-overlooked form of diversity. We suggest that including accessibility topics when teaching user-interface development skills is a low-effort task that can directly support teaching core software development principles such as \"separation of concerns\" and \"standards compliance.\" In this lightning talk we describe our initial efforts to integrate accessibility and accessible design as \"first-class\" topics into our department's required course on web development, including specific examples of concepts covered, classroom activities, and assignments. We also discuss suggestions for how to potentially integrate accessibility topics into other computer science courses which include any kinds of front-end user interfaces. The goal of this talk is to promote awareness of accessibility concerns, demonstrate the ease by which educators can include such material, and encourage discussion about how to engage students in such diversity considerations throughout the curriculum.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130038983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a unique model of inter-class student collaboration that motivates creativity, expands the scope of collaborative research and enables handling of conceptual gaps through inter-class peer mentoring. The proposed model engages students from an upper level class with students of a lower level class so that they can connect with each other in a peer mentor-mentee relationship to overcome conceptual gaps in learning. It provides upper level students with an exclusive opportunity to reinforce their conceptual grasps and engage in research for addressing the problems faced by lower level students. This proposed model of improvised peer collaboration promotes a new kind of service-oriented learning project in computing that inspires innovation and leads to research on finding ways to handle common conceptual limitations, thereby helping student retention by assisting lower level peer mentees. It also assists upper level peer mentors in self-driving towards research oriented thinking for inventing methods to solve authentic conceptual issues. The proposed model has been currently implemented in the UWGB computing curriculum, where CS2 students have been collaborating with CS1 students and have been participating in computing educational research as part of the process. These ongoing research experiments have analyzed the performance of the proposed model through data obtained by conducting student surveys. The collected survey data represent insightful evidences from preliminary evaluations of the proposed model.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129263000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an effort to increase the interest of students in studying within these fields, many commercial, governmental, and non-for-profit educational groups have sponsored numerous activities aimed to expose students to computing prior to college. With the advent of CS for All, there is further need to research these programs and evaluate their effectiveness. This session will gather researchers and practitioners interested in researching the impact that pre-college computing activities have on their participants. Participants will learn about a new initiative underway to make the job of collecting and tracking data easier. To be useful for the broader community, this NSF-funded IUSE initiative requires input from the community it wishes to serve. Participants will have the opportunity to provide valuable input on what their needs are for tracking such activities and what tools may be helpful for them, including methods for data collection to produce meaningful data that can be compared to data provided by other researchers and practitioners. The focus of this discussion will be the long-term impact of these activities; however, we will discuss data collection techniques researchers have used in the past to gauge short-term impact as well.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129646635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Students receive immediate feedback from the grader, and can resubmit to correct errors as needed. Through an online interface, TAs can access detailed grading results and supplement the automated scores with manual grading (numeric and written feedback) of overall program structure, good use of comments, reasonable error checking, etc. and any non-programming components of the assignment. The instructor can also configure the system to allow for a configurable late day policy on a per assignment and per student basis. We currently use Submitty in eight different courses (spanning from introductory through advanced topics) serving over 1500 students and 35+ instructors and TAs each week. We will present a range of \"case study\" assignment configurations in a hands-on demo, going from simple through complex, using a variety of different automated grading methods including per-character and per-line output difference checkers, external unit testing frameworks (such as JUnit), memory debugging tools (Valgrind and DrMemory), code coverage (e.g., Emma), static analysis tools, and custom graders. Submitty can be customized per test case as appropriate to apply resource limits (running time, number of processes, output file size, etc.) and to display or hide from students the program output, autograding results, and testing logs.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130231441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
