Graph-Based Learning, Jason Gronn

Honors Projects

An educational approach to teaching students based on prerequisite knowledge they may or may not have is presented. This approach represents educational content in the form of a graph, where edges link each topic to the prerequisites of that topic. A proof-of-concept website is created based on this approach, where qualitative results are observed and a number of conclusions are drawn. Some of the findings are that, while it can prevent users from being confused by lacked prior knowledge, the users may instead be confused by the presentation of the graph structure. The work finds that the approach is workable, …

Hearing Iterative And Recursive Behavior: Sonification Improves Student Understanding, Joel C. Adams, Hayworth Anderson

University Faculty Publications and Creative Works

Abstract topics such as recursion are challenging for many computer science students to understand. In this experience report, we explore function sonification-the addition of sound to a function to communicate information about the function's behavior in real-time as it runs-as a pedagogical approach for improving students' understanding of recursion. We present several example iterative and recursive function sonifications, plus spectrograms that illustrate their different sonic behaviors. We also present experimental evidence that using these sonifications significantly improved the understanding of recursion for students who used them, compared to students who used silent (i.e., traditional) versions of the same functions. Based …

Introducing Flexible Assessment Into A Computer Networks Course: A Case Study, Joe Meehean

Journal of Mathematics and Science: Collaborative Explorations

With overall positive results and limited drawbacks, I have adapted modern pedagogical techniques to address a common difficulty encountered when teaching a computer networks course. Due to the tiered nature of the skills taught in the course, students often fail unnecessarily. Using mastery learning, competency-based education, and specifications grading as a foundation, I have developed a course that allows students with varied skills and abilities to pass. The heart of this approach is the flexible assessment of programming assignments which eliminates due dates and allows students to have their work graded and regraded without penalty. Flexible assessment also defines an …

Modeling Elementary Students' Computer Science Outcomes With In-School And Out-Of-School Factors, Umar Shehzad

Instructional Technology and Learning Sciences Faculty Publications

While the last two decades have seen an increased interest in STEAM (science, technology, engineering, arts, and mathematics) in K-12 schools, few efforts have focused on the teachers and teaching practices necessary to support these interventions. Even fewer have considered the important work that teachers carry out not just inside classrooms but beyond the classroom walls to sustain such STEAM implementation efforts, from interacting with administrators to recruiting students and persuading parents about the importance of arts and computer science. In order to understand teachers’ needs and practices regarding STEAM implementation, in this paper, we focus on eight experienced computer …

Immersive Learning Environments For Computer Science Education, Dillon Buchanan

Electronic Theses and Dissertations

This master's thesis explores the effectiveness of an educational intervention using an interactive notebook to support and supplement instruction in a foundational-level programming course. A quantitative, quasi-experimental group comparison method was employed, where students were placed into either a control or a treatment group. Data was collected from assignment and final grades, as well as self-reported time spent using the notebook. Independent t-tests and correlation were used for data analysis. Results were inconclusive but did indicate that the intervention had a possible effect. Further studies may explore better efficacy, implementation, and satisfaction of interactive notebooks across a larger population and …

Impact Of The Pandemic On Computer Science Education, Dwight Miller, Guy Trainin

Research and Evaluation in Education, Technology, Art, and Design

This poster examines the impacts of the Covid-19 pandemic on computer science education in Nebraska. Data collected by Code.org on student and teacher engagement in CS education in Nebraska public and private schools helps paint a picture of the changing landscape.We reveal a significant decrease in rural student participation since the 2019-20 school year, a minimal increase in the number of teachers teaching with Code.org, and a significant drop in participation of girls at the secondary level. By uncovering these trends in engagement, we hope to inform and inspire educators and administrators to take action.

Exploring Elementary Student And Teacher Perceptions Of Stem And Cs Abilities, Scott R. Bartholomew, Vanessa Santana, Jessica Yauney

Journal of STEM Teacher Education

Curriculum, legislation, and standards across the nation are quickly evolving to incorporate computer science and computational thinking concepts into K-12 classrooms. For example, many states have passed legislation requiring computer science to be included in every school’s curriculum. Most states, however, report high shortages of qualified computer science teachers, meaning, teachers without extensive training will be required to integrate these concepts into their classrooms—a daunting task for most teachers without the necessary background and experiences. This paper reports the impacts of a thirteen-week intervention in a local elementary school designed to introduce computational thinking skills to 4^th and 5 …

Addressing The "Leaky Pipeline": A Review And Categorisation Of Actions To Recruit And Retain Women In Computing Education, Alina Berry, Susan Mckeever, Brenda Murphy, Sarah Jane Delany

Conference papers

Gender imbalance in computing education is a well-known issue around the world. For example, in the UK and Ireland, less than 20% of the student population in computer science, ICT and related disciplines are women. Similar figures are seen in the labour force in the field across the EU. The term "leaky pipeline"; is often used to describe the lack of retention of women before they progress to senior roles. Numerous initiatives have targeted the problem of the leaky pipeline in recent decades. This paper provides a comprehensive review of initiatives related to techniques used to boost recruitment and improve …

Teaching Computer Science: An Exploration Of Habits Of Mind, Lauren Hays, Jenna Kammer

The Advocate

Previous research has indicated that many K-12 computer science teachers do not have a background in computer science education. This means, computer science teachers are not necessarily using established habits of mind they learned from their own studies. The purpose of this study is to understand more about the habits of mind needed by computer science educators, and students, who often have varying levels of ability and knowledge of computer science.

We answer the following research questions:

1. How do teachers of computer science use teaching strategies to develop the habits of mind needed for computing?
2. What habits of mind do …

Impact Of User Traversal On Performance Of Stem Learners In Immersive Virtual Environments, Eric W. Nersesian

Dissertations

The emerging technologies of augmented and virtual reality (AR/VR) may have vast implications to societal communication and representation of information. AR/VR computer interfaces are unique in that they may be placed spatially around the user in three-dimensional (3D) space; this affords new methods of both presentation and user interaction with the target information.

This may be especially impactful in the education of science, technology, engineering, and mathematics (STEM) professionals. Prior research has shown that simulations and visualizations improve the performance of STEM learners compared to live instruction and textbook reading. Yet, research into AR/VR as a learning environment for widespread …

Translanguaging About, With, And Through Code And Computing: Emergent Bi/Multilingual Middle Schoolers Forging Computational Literacies, Sara Vogel

Dissertations, Theses, and Capstone Projects

As computing pervades more aspects of life, and as Computer Science for All (CS for All) initiatives roll out across the U.S., the field must understand the experiences and language practices of emergent bi/multilingual K-12 students and use that knowledge to drive equitable pedagogical and programmatic approaches. But little is known about how emergent bi/multilingual students — a growing population that school systems have often viewed with deficit-based lenses and have thus struggled to educate equitably — use language in the context of CS education. This dissertation addresses this gap by (1) qualitatively documenting and using asset-based frames to analyze …

Much of maker education’s expansion has focused on STEM (science, technology, engineering, mathematics) learning, leaving out equally promising opportunities for integrating arts learning. In this paper we share findings from a project in which high school students created electronic-textiles-based art representing features of a community important to them as a part of an elective high school computer science class. We addressed the following research questions: (1) What kinds of personal and community meanings did students convey through their maker projects? (2) How did students engage with artistic dimensions in their projects? (3) How did coding interactive features support students’ artwork? …

Re-Shape: A Method To Teach Data Ethics For Data Science Education, Benjamin R. Shapiro, Amanda Meng, Cody O'Donnell, Charlette Lou, Edwin Zhao, Bianca Dankwa, Andrew Hostetler

Learning Sciences Faculty Publications

Data has become central to the technologies and services that human-computer interaction (HCI) designers make, and the ethical use of data in and through these technologies should be given critical attention throughout the design process. However, there is little research on ethics education in computer science that explicitly addresses data ethics. We present and analyze Re-Shape, a method to teach students about the ethical implications of data collection and use. Re-Shape, as part of an educational environment, builds upon the idea of cultivating care and allows students to collect, process, and visualizetheir physical movement data in ways that support critical …

Introducing Parallelism To First-Year Cs Majors, Barbara M. Anthony, D. Cenk Erdil, Olga Glebova, Robert Montante

School of Computer Science & Engineering Faculty Publications

We propose to strengthen the computer science (CS) curriculum by embedding parallel concepts in a required first-semester seminar taken by all incoming declared CS majors. We introduce students to parallel computing concepts through a series of unplugged activities so that students see parallel approaches as a natural form of solution to a task. We describe a pilot offering of the class and activities, with measurements and analysis of what students self-report and their performance on assessments.

Understanding different reasons for teaching computer science isn’t just important so that we can get other people to care about CS, they should also shape what computer science education efforts look like - who gets opportunities to learn, what kinds of things get taught and in what ways. Our values should be expressed in our practice.

Exercises Integrating High School Mathematics With Robot Motion Planning, Ronald I. Greenberg, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

This paper presents progress in developing exercises for high school students incorporating level-appropriate mathematics into robotics activities. We assume mathematical foundations ranging from algebra to precalculus, whereas most prior work on integrating mathematics into robotics uses only very elementary mathematical reasoning or, at the other extreme, is comprised of technical papers or books using calculus and other advanced mathematics. The exercises suggested are relevant to any differerential-drive robot, which is an appropriate model for many different varieties of educational robots. They guide students towards comparing a variety of natural navigational strategies making use of typical movement primitives. The exercises align …

Recent discussions of making have focused on developing out-of-school makerspaces and activities to provide more equitable and enriching learning opportunities for youth. Yet school classrooms present a unique opportunity to help broaden access, diversify representation, and deepen participation in making. In turning to classrooms, we want to understand the crucial practices that teachers employ in broadening and deepening access to making. In this paper, we investigate two high school teachers’ approaches in implementing a novel eight-week, electronic textiles unit within the Exploring Computer Science curriculum, where students designed wearable electronic textile projects with microcontrollers, sensors, and LEDs. We share teachers’ …

People Like Me: Providing Relatable And Realistic Role Models For Underrepresented Minorities In Stem To Increase Their Motivation And Likelihood Of Success, Nir Aish, Philip Asare, Elif Eda Miskioglu

Faculty Conference Papers and Presentations

Despite efforts to increase participation of racial and ethnic minorities (excluding Asians) in science, technology, engineering and mathematics (STEM) in the United States, this group remains underrepresented in these fields. Many efforts to increase minority participation focus on support structures to help this group “get through” the pipeline. However, less attention has been paid to increasing their intrinsic motivation to pursue careers in STEM. Our work is focused on increasing this intrinsic motivation, looking at role models as external influences. Underrepresented minorities are faced with a limited role model pool and in many cases with role models (who we call …

We report on the strengths of various survey responses and their relationships, and we compare student responses by race and gender. The data …

The Impact Of The Exploring Computer Science Instructional Model In Chicago Public Schools, Ronald I. Greenberg

Ronald Greenberg

As part of the Taste of Computing project, the Exploring Computer Science (ECS) instructional model has been expanded to many high schools in the Chicago Public Schools system. We report on initial outcomes showing that students value the ECS course experience, resulting in increased awareness of and interest in the field of computer science. We compare these results by race and gender. The data provide a good basis for exploring the impact of meaningful computer science instruction on students from groups underrepresented in computing; of several hundred students surveyed, nearly half were female, and over half were Hispanic or African-American.

Pythagorean Approximations For Lego: Merging Educational Robot Construction With Programming And Data Analysis, Ronald I. Greenberg

Ronald Greenberg

Abstract. This paper can be used in two ways. It can provide reference information for incorporating diagonal elements (for bracing or gear meshing) in educational robots built from standard LEGO kits. Alternatively, it can be used as the basis for an assignment for high school or college students to recreate this information; in the process, students will exercise skills in both computer programming and data analysis. Using the paper in the second way can be an excellent integrative experience to add to an existing course; for example, the Exploring Computer Science high school curriculum concludes with the units “Introduction to …

Experiences With Scala Across The College-Level Curriculum, Konstantin Läufer, George K. Thiruvathukal, Mark C. Lewis

Konstantin Läufer

Various hybrid-functional languages, designed to balance compile-time error detection, conciseness, and performance, have emerged. Scala, e.g., is interoperable with Java and has become an early leader in adoption, especially in the start-up and open-source spaces. As educators, we have recognized Scala’s value as a teaching language across the CS curriculum. In CS1, the read-eval-print loop and simple, uniform syntax aid programming in the small. In CS2, higher-order methods allow concise, efficient manipulation of collections. In a programming languages course, advanced constructs facilitate the separation of concerns, program representation and interpretation, and concurrent programming. In advanced applied courses, language mechanisms and …
