Interactive learning is a new approach: educators teach small chunks of content in short cycles of theory, example, exercise, solution and feedback. It is based on active, computer-based and experiential learning and focuses on immediate feedback to improve the learning experience. It allows students to reflect about the content incrementally. It includes hands-on activities, guidance by the instructor and increases students' motivation and engagement. This workshop describes experiences of multiple interactive learning courses for large classes, including exercises for (1) multiple choice quizzes, (2) interactive tutorials, (3) interactive programming exercises, (4) interactive modeling, and (5) team activities. Based on our experience, we present multiple case studies and concrete examples of interactive exercises. While the assessment of many exercises can be (semi-)automated, teaching assistants in the classroom manually assess other exercises. We show how educators can integrate these exercises into large classes without significantly increasing their effort. Participants should bring a laptop to this workshop.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"53 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":"134085745","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}

This technique enables students to retain content while also learning process skills such as communication and teamwork. Developing POGIL activities and facilitating them takes practice and experience. Few, if any, current faculty have been taught using POGIL activities and so have less experience to bring to their development and especially to their incorporation into the classroom. The skills and preparation for delivering an effective POGIL class are very different than faculty have seen in action. The 5 practices: Anticipating, Monitoring, Selecting, Sequencing, and Connecting can be used to better understand how to prepare for and facilitate POGIL activities. While the POGIL organization (pogil.org) has many training sessions, including facilitator training available, most computer science materials still do not incorporate facilitator information that goes beyond the answers to the questions and suggested timing for sections of activities. A brief example of an activity prepared using the 5 practices will be shared to illustrate the potential along with anecdotes and tips for transitioning from traditional lecture to POGIL activities in the classroom.","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":"134119059","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}

The demand for trained professionals in the field of Big Data technologies is huge, and there is urgent need to develop and update courses in this area. One of the biggest hurdles for many schools is establishment, maintenance, and constant update of high performance computing infrastructure. Further, the technology landscape for Big Data is constantly evolving, and newer technologies, such as Apache Spark, require significant expenditure to set up and upgrade at the cluster level. Traditional infrastructure at most higher educational institutions is insufficient for this, and is also not able to scale up to meet the expectations of large class sizes and multiple simultaneous sessions. In this lightening talk, we will share our experience of running large undergraduate and graduate Big Data courses using open source infrastructure. Some of this infrastructure is cloud based, while others require students to create virtualized environment on their personal computers. Both types of resources are freely available, easy to setup, and provide students with enough computational power to run most academic tasks and projects. We will provide specific examples of using such technologies for common tasks, such as setting up a distributed file system, running MapReduce algorithms on large datasets, performing large scale machine learning and graph mining using Apache Spark, and maintaining a high availability Cassandra instance.","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":"134157025","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}

This belief is not unfounded as the majority of online computer science teaching materials require modern technology and Internet connectivity, making these tools inaccessible to the low-tech classroom. As a solution, we developed SAS® CodeSnaps, a free tool that provides an engaging coding experience with minimal technology. One iPad and one robot (www.sphero.com) are all that is needed for every student in a classroom to code. With CodeSnaps, students program together using printable coding blocks. When their program is ready, they \"snap\" a picture using the CodeSnaps app which digitizes their code and executes it on a robot, allowing students to see their program execute in the real world. In this poster we present lesson plans for both a single engagement with students as well as week-long introduction to CS fundamentals centered around the CodeSnaps app. We also discuss results from two pilot studies designed to measure student engagement during these lessons.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"16 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":"134389855","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}

Unlike encryption, covert communication allows to send information covertly, using an otherwise legitimate medium of transfer, thus it is not apparent that a message is being transferred at all. There is limited research on Covert Timing Channels (CTCs), i.e., channels that manipulate packet inter-arrival time to exchange messages based on a certain encoding. Implementing and testing CTCs in real network environments is lacking in the current literature due to sensitivity to network delays that significantly affects this type of communication. Thus, it is important to implement CTC communication to analyze the challenges of creating robust, efficient, and undetectable channels in real life situations. It is also paramount to test these implementations in a wide range of realistic network conditions. In this research, we have developed and tested two implementations of CTCs. The first implementation is based on [1] using standard bits encoding and ASCII for simplicity and robustness. This implementation suffers from easy detection. On the other hand, we developed the second implementation with goal to make the channel undetectable by using encoding with five different delays, i.e., symbols, where five symbols in a specific order correspond to one letter of the alphabet. This implementation has sufficient randomness to be undetected with standard statistical mechanisms. We have tested both implementations on local networks, the Global Environment for Network Innovations (GENI) controlled environment, networks across states in the US, and internationally.","PeriodicalId":344382,"journal":{"name":"Proceedings of the 2017 ACM SIGCSE Technical Symposium on Computer Science Education","volume":"70 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":"131750867","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}

The community has primarily focused on high school implementations, which have different situational factors than university courses (e.g., amount of class time). In this poster, we present the design of a survey course that aligns with CS Principles and also continues the long tradition of breadth-first introductions to computer science at the college level. We describe the instructional strategies, assessments, and curriculum details, providing a model for how to modify existing CS0 courses. We also outline twelve lab activities that support the computational thinking practices and learning objectives of the AP curriculum framework. All instructional materials including activities, labs, performance tasks, and rubrics are freely available on the course website: https://w3.cs.jmu.edu/cs101. Quizzes, solutions, and other materials are also available to instructors upon request.
