Welcome to the CS-Ed podcast, a podcast where we talk about teaching computer science with computer science educators to learn how they teach and manage their classrooms.
In this episode, we talk with David Malan from Harvard University, Professor of the Practice of Computer Science in the School of Engineering and Applied Sciences. He teaches Computer Science 50, Harvard University’s largest course. Our conversation focused on CS50 tools. An overview of the tools is in a YouTube video David provided. We spent most of our time talking about help50 and style50. Help50 is a tool that, when fed error output, returns a suggestion or question a student should focus on to help interpret the error output. Style50 is a tool to help students fix the style of their code
In this episode, we talk with Dan Garcia, a teaching professor at UC Berkeley in the EECS Department. He was selected as an ACM Distinguished Educator in 2012 and ACM Distinguished Speaker in 2019. He has won all four of his department’s computer science teaching awards. Our conversation focused on designing exams, which he boiled down to his five-finger rule: (1) material coverage, (2) reasonable time, (3) range of difficulty, (4) variety of question types, and (5) ease of grading. His “something awesome in computer science” highlighted his mentors Mike Clancy and Brian Harvey, who are both e
In this episode, we talk with Amy Ko, an Associate Professor at the University of Washington Information School. She directs the Code & Cognition Lab and studies human aspects of programming. Our conversation focused on how to teach students to debug, a skill many of us undoubtedly struggle to get our students to do effectively. Amy suggests: step 1 is to have students articulate what is happening versus what should happen (current output versus correct output). Step 2 is brainstorm different ways (hypotheses) that might be causing the discrepancy and exploring each idea to see if it is the ca
In this episode, we talk with Mark Guzdial, Professor of Electrical Engineering and Computer Science, with a courtesy appointment in the School of Information at the University of Michigan. Our conversation focused on live coding, which is programming in front of the class as the students would program. Mark emphasized that the most essential part of live coding is modeling process. The second part is modeling how to manage mistakes. And the third is to create opportunities for students to make predictions. For his “something awesome in computer science,” Mark talked about how he loved that co
In this episode, we talk with Armando Fox, Professor of Computer Science and Faculty Advisor to the MOOCLab at UC Berkeley. With David Patterson, he co-designed and co-taught Berkeley’s first Massive Open Online Course (MOOC) on “Engineering Software as a Service,” offered through edx.org. It is now a professional certificate in “Agile Development Using Ruby on Rails. Our conversation touched many topics involving MOOCs. We discussed the history of MOOCs, how he got into it, creating Small Private Online Courses (SPOCs), how MOOCs call into question established teaching habits, some experiment
In this episode, we talk with Colleen Lewis, Associate Professor of Computer Science at Harvey Mudd College. She specializes in computer science education and diversity issues, as well as is the creator of http://csteachingtips.org/, which we at the CS-Ed Podcast post about often. This conversation was a question and answer with Colleen. Our topics included: peer instruction, how she structures her lecture and class, how becoming a better and better teacher is a marathon, cheating on assignments, the pros and cons of splitting students based on prior experience, and where to hold office hours.
We are launching season 2 of The CS-Ed Podcast on January 4th, 2021! The year 2020 has caused so much disruption and calls for change, which led us to make this season's theme "Where should we go from here?" Join us for this season as our host, Kristin Stephens-Martinez, discusses with her guests about pedagogy and inequality in hopes it will give us all an opportunity to reflect rather than react to our present situation. This season has 6 episodes. The first will come out on January 4th and we'll release subsequent episodes every other Monday: 1/4 - Manuel Pérez-Quiñones from University Nort
In this episode, we talk with Manuel Pérez-Quiñones, a Professor at the University of North Carolina at Charlotte. Our topic is supporting students of color. We discussed why this support matters and the differences between professors versus students and equality versus equity. We also discussed how he changed his grading practices for his remote class. He even shared about changing his syllabus to specification grading, which he reflects on in his blog now that the semester is over. For his too long; didn’t listen summary, Manuel talked about how we need to acknowledge the history that got us
Our guest today is Jared O’Leary, the Director of Education and Research at BootUp PD. Jared creates computer science curriculum and professional development and is also the creator of the CSK8 podcast. Our topic was what K–12 and higher education computer science education can learn from each other. We discussed Jared’s philosophy and curriculum design process, as well as why K–12 and higher education do not communicate as much as would be ideal. In Jared’s too long; didn’t listen summary, Jared discussed the importance of reading and learning from outside of the field and how we need to figu
In this episode, we talk with Nicki Washington, a full Professor of the Practice at Duke University, about cultural competence. We discuss the definition of cultural competence. Its history, why we should care, and what it means in the context of computer science. We also talked about Nicki's new class on this topic and her 3C Fellows program. Finally, we close with a call to action. Many people and organizations have started learning, reading, and making commitments. What needs to happen next is to start executing plans and iterating on them quickly (agile method style). We need to hold peopl
Joining us today is Joe Feldman, author of Grading for Equity and the CEO of Crescendo Education Group. We discuss the historical overview of grading and why now is a good time to rethink our grading process to make it more equitable. We got concrete by discussing our host’s, Kristin Stephens-Martinez’s, syllabus for her class and changes she was considering after reading Grading for Equity. One significant point Joe made is that grades should only convey the student’s level of mastery, not their behavior. Finally, we closed the episode with him pointing out we should do small experiments, ite
In this episode, we talk to Leigh Ann DeLyser, co-founder and executive director of CSforAll. Our topic is the need to reform systems for sustainable equity. We discuss what it means and what CSforAll does. We also discussed the specific difficulties our host, Kristin Stephens-Martinez, has with her CS1 class and how it’s actually a systems problem.
For this season’s last episode, we talk with Jacqueline Smith, an Assistant Professor of the teaching stream in the Department of Computer Science at the University of Toronto. We talk about U of T’s large flipped CS1. We started with the class’s specifics, how it’s flipped, and their “prepare, rehearse, and perform” cycle. Then we discussed their decision to have a synchronous part of the class despite remote teaching. We spent the rest of the episode on her thoughts on how best to flip a class, which included reconsidering if video is the right medium, flipping doesn’t need to happen all at
Hello, everyone! We are going to have a season 3! But we are going to try something new. Rather than six episodes released every few weeks, we are going on an irregular schedule. We’re picking a theme and running with it until we run out. This season’s theme is “What’s next?” where we focus on how we've rethought our teaching since covid-19. We’ve got a few episodes lined up and the goal is to release an episode on average every other month. So make sure to subscribe, so you don't miss an episode!
In a two-part episode series, we talk with Kevin Lin and Brett Wortzman from the University of Washington about alternative grading practices. In this episode, we focus on the purposes and goals of grading and discuss different types of grading systems. We dig into the philosophy of Kevin and Brett’s grading approach, how it can work in very large courses, and how to get buy-in from students on an unfamiliar system. Kevin mentions the importance of focusing on equity and defining what exactly that means, and Brett emphasizes that grading should align with the course’s learning outcomes. We clo
In part two of our episode series with Kevin Lin and Brett Wortzman from the University of Washington, we dig into the details of how they implement their alternative grading systems. Brett outlines their ESNU system that stands for exemplary, satisfactory, not yet and unaccessible, as well as the components of his grading system for his large CS1 course, and Kevin talks about his version from his CS2 and other data structures courses. We discuss trading off complexity for precision and how much differentiation in grades is actually feasible and necessary. We also talk about grading workload a
In this episode, we talk with Michael Ball from the University of California, Berkeley. Our focus is on undergraduate teaching assistants (TAs), which Berkeley has a long history of. Michael goes into detail about what Berkeley TAs do, the TA hierarchy, and TA training. We learn about a small core group of students that make an undergraduate career out of being TA. Another question we focus on is advice to an institution that is just starting its TA program. Finally, throughout our talk, we discuss how things are different from before the pandemic and now.
Today's episode is with Richard Ladner from AccessComputing and AccessCSforAll, Professor Emeritus from the University of Washington. Our discussion focuses on accessibility. How do we improve accessibility in our teaching? What do AccessComputing and AccessCSforAll do? And how do we be considerate of our students that are hard of hearing, blind, or have some other accessibility need? Edited by Michael Ball
Teaching Associate, what's that? In this two-part series's first episode, we talk with Kate O'Hanlon, a teaching associate in the computer science department at Duke University. Teaching associates are department staff positions that support the large enrollment classes. We discuss the four primary teaching associate responsibilities: project manager, student outreach, developer, and instructor. In addition, we discuss the underlying goal when Duke created the position and the needed flexibility within the role. This episode is part of a two-part series. The second episode will be with another
Here’s episode two of our two-part series on teaching associates! A teaching associate is a teaching support staff position here at Duke University. This episode is a conversation with Yesenia Velasco. We talk about how her role is different than Kate O’Hanlon from our last episode, reflect on how Duke did at its first attempt at such a position, and look towards the future of where such a position can go.
In this episode, we talk with Amogh Mannekote, a Ph.D. student at the University of Florida. He and others analyzed class forum data from three very different classes and discovered that a lot of factors influence how students use the class forum, including the kind of class assignments, the accessibility of other sources of help, and how the instructor or TAs answer questions on the class forum. After doing this work, he also strongly believes that instructors should download and analyze their data or we should create more "out of the box" open source tools that do this for instructors.

AIICE stands for Alliance for Identity Inclusive Computing Education. It is an organization dedicated to "empowering the next generation of computer scientists by eliminating systemic barriers." This episode is with Dr. Shaundra (Shani) B. Daily, Ph.D., the backbone director of the organization. We discuss how she and her Co-PI, Dr. Nicki Washington, Ph.D., and past podcast guest, wrote the grant that started it all, how we should stop trying to "fix" students, that we should instead focus on fixing the systems that "requires" "fixing" students, and about their 3C program, a professional devel
In this episode, Sarah Heckman from North Carolina State University and our host discuss the Peer Teaching Summit at SIGCSE Technical Symposium 2022. We cover what a peer teacher is, more commonly known as an undergraduate or graduate teaching assistant, and how they support student help-seeking. The summit brought together many people with peer teachers at their schools where they discussed what they can and cannot do, and how every school is unique. Afterward, we focused on office hours and how there was a surprising variety of handling them, including what information students see in the of
Join us in a conversation with Iris Howley from Williams College about Primarily Undergrad Institutions (PUIs). Where we talk about what a PUI is, the research and teaching expectations, what the interview cycle is like, and compare a PUI professor with a teaching track professor. The biggest takeaway from this episode is that PUIs exist, they don't look like the school someone is getting their Ph.D. at, and they are an option post-graduation. More info is at http://bit.ly/cspui-jobs Finally, make sure to check the deadlines soon. They usually interview in the fall!
