Title: Real-World Problems, Data, and Visualizations Using BRIDGES (PreConference Workshop)
The rise in CS enrollments in the past few years has also resulted in a more diverse population of learners that have different expectations, motivations and interests, making it important to provide relevant learning materials in early foundational courses. Grounding Computer Science concepts in reality by solving important real-world or fun problems are keys to increasing students’ motivation and engagement in computing, which may help improve student retention and success. This workshop provides instructors with a hands-on introduction to BRIDGES, a software infrastructure for programming assignments in early computer science courses, such as CS1, CS2, data structures, and algorithm analysis. BRIDGES provides the tools for creating engaging programming assignments, including: (1) a simplified API for accessing real-world data, such as those from social networks, entertainment (songs, movies), science, engineering (USGIS Earthquakes, elevation maps), geography (OpenStreet maps), and literature (Project Gutenberg), (2) creating visualizations of the data, (3) an easy to use API for game-based assignments, and, (4) algorithm benchmarking. Workshop attendees will engage in hands-on experience using BRIDGES with multiple datasets, have the opportunity to discuss the challenges they face in their own courses, and how BRIDGES can be used in their own courses. Using BRIDGES in data structures, algorithms, and other courses have shown improved retention of CS knowledge and better student performance in follow-on courses, when compared to students from other sections of the same course. BRIDGES has impacted nearly 2000 students across 20 institutions since its inception 5 years ago. A repository of BRIDGES assignments is now maintained for instructors using BRIDGES in their classes.  more » « less

  1. Despite increasing enrollments in CS in recent years, retention of CS majors to meet current and future workforce needs remains a major concern. Grounding Computer Science concepts by solving important real-world problems or fun problems can be keys to increasing students’ motivation and engagement in computing, and may provide a path to improving retention in CS programs. This tutorial provides instructors with a hands-on introduction to BRIDGES, a software infrastructure for programming assignments in early computer science courses, including introductory programming (CS1, CS2), data structures, and algorithm analysis. BRIDGES provides capabilities for creating engaging programming assignments, including: (1) a simplified API for accessing real-world data sets}, including social networks; scientific, government, and civic organization data; and movie, music, and literature collections; (2) interesting visualizations of the data, (3) an easy to use API that supports creation of games, and, (4) algorithm benchmarking. Workshop attendees will engage in hands-on experience with BRIDGES and will have the opportunity to discuss how BRIDGES can be used in their own courses.

  2. This workshop provides instructors with a hands-on introduction to BRIDGES, a software infrastructure for programming assignments in early computer science courses, including introductory programming (CS1, CS2), data structures, and algorithm analysis. BRIDGES provides capabilities for creating more engaging programming assignments, including: (1) a simplified API for accessing real-world data sets, including from social networks; scientific, government, and civic organizations; and movie, music, and literature collections; (2) interesting visualizations of the data, (3) an easy to use API that supports creation of games that leverage real-world data, and, (4) algorithm benchmarking. Workshop attendees will engage in hands-on experience with BRIDGES with multiple datasets and will have the opportunity to discuss how BRIDGES can be used in their own courses.

  3. BRIDGES is a software framework for creating engaging assignments for required courses such as data structures and algorithms. It provides students with a simplified API that populates their own data structure implementations with live and real-world data, and provides the ability for students to easily visualize the data structures they create as part of routine classroom exercises. The objective is to use the infrastructure to promote a better understanding of the data structure and its underlying algorithms. This report describes the BRIDGES infrastructure and provides evaluation data collected over the first five years of the project. In the first 2 years, as we were developing the BRIDGES projects, our focus was on gathering data to assess whether the addition of the BRIDGES exercises had an effect on student retention of core concepts in data structures; and throughout the 5-year duration of the project, student interest and faculty feedback were collected online and anonymously. A mixed method design was used to evaluate the project impact. A quasiexperimental design compared student cohorts who were enrolled in comparable course sections that used BRIDGES with those that did not. Qualitative and quantitative measures were developed and used together with course grades and grade point averages. Interest and relevance in BRIDGES programming assignments was assessed with additional survey data from students and instructors. Results showed that students involved in BRIDGES projects demonstrated larger gains in knowledge of data structures compared to students enrolled in comparable course sections, as well as long-term benefits in their performance in four follow-on required courses. Survey responses indicated that some investment of time was needed to use BRIDGES, but the extra efforts were associated with several notable outcomes. Students and instructors had positive perceptions of the value of engaging in BRIDGES projects. BRIDGES can become a tool to get students more engaged in critical foundational courses, demonstrating relevance and context to today’s computational challenges.

  5. This demo introduces participants to the concepts and application of BRIDGES, a software infrastructure designed to facilitate hands-on experience for solving traditional problems in introductory computer science courses using data from real-world systems that are of interest to students, such as Facebook, Twitter, and Google Maps. BRIDGES provides access to real-world data sets for use in traditional data structures programming assignments, without requiring students to work with complex and varied APIs to acquire such data. BRIDGES also helps the students to explore and understand the use of data structures by providing each student with a visualization of operations performed on the student's own implementation of a data structure. BRIDGES visualizations can be easily shared (via a weblink) with peers, friends, and family. Demo attendees will see (and possibly engage in) hands-on experience with BRIDGES and will have the opportunity to discuss how BRIDGES can be used to support various introductory computer science courses. Additionally, the demo will complement our oral presentation of our work at SIGCSE, by providing hands-on demonstrations of BRIDGES.
