Peer code review is a key practice in professional software development, and its integration into computer science education can provide valuable learning experiences for students. However, few reports compare different peer code review methods within a single educational context. This experience report shares insights from implementing various review types-individual, team, and pair code reviews-in a first-year data structures and algorithms course in a bachelor's degree program. Throughout the semester, students took an active role in their learning by completing three programming assignments, each followed by a different peer review method. Feedback was collected through questionnaires to capture the students' perceptions of their data structure knowledge, programming skills, and overall learning experience. Our report outlines the design of the different review learning activities, provides insights into the students' opinions on the review techniques, and reflects on the challenges and successes we encountered. As each method offers unique benefits, we believe that incorporating a variety of peer code review methods can enhance the overall learning experience in computer science courses.

data structures and algorithms (DSA) are one of the main pillars of software development;however, abstractions around them are hard to teach and to be understood by students. The most common approaches adopted by instructors to demonstrate the behavior of DSAs are the use of resources like slides and whiteboard sketches to create program illustrations. This task may be slow and tedious because these illustrations need to be continuously updated to represent new algorithm inputs and modifications. In this paper, we propose Willow, a tool for Program Visualization Simulation (PVS), which supports user interactions to manipulate the generated visualizations. With these manipulations in the visualization, we expect the user to be able to create better examples, resembling Algorithm Visualization Simulation tools (AVS), which are specialized in providing visualizations for specific DSAs. We evaluated our tool through a preliminary qualitative study with teaching assistants from an introductory Computer Science course who all give review lessons to the students. Our preliminary results show that the tool was well accepted by the participants, but we still need more studies to validate the use of the tool in classrooms. With the use of our tool features in the teaching-learning process, we expect that instructors may be able to interactively and more clearly explain DSAs to their students, without the hassle of hours creating slides or drawing by hand messy examples of algorithms.

The teaching of practical foundations of computer science is still a big challenge. The course on data structures and algorithms is one of the most important foundational courses that are necessary to be included in the curriculum of future IT experts. The content of this course is quite wide and it differs in many universities. In our teaching process, we identified some interesting problems that could be presented more attractively - using the visualizing software. In this paper, we present a purpose, role, design and methodology of our developed software tool for the convenience of teaching and studying the problem of the longest common subsequence.

data structures and algorithms course is a core foundation stone in a computer science curriculum. But there are many complicated algorithms in it. In order to help students to master the algorithms, this paper describes the use of blended learning in data structures and algorithms course teaching. This blended learning model is realized as a combination of teaching methods mixed, project-based teaching, E-learning, course experiment and design mixed, process evaluation and overall evaluation. From the obtained results with performed experimental evaluation, the realized blended learning model may provide more effective and efficient educational experience.

HFOSS-Lite in CS2: Incorporating the Ushahidi Crowdmapping Program in a data structures and algorithms Course (Abstract Only) 15

Although undergraduate computer science enrollments are again on the upswing, increased enrollments do not seem to have led to increased diversity -- CS, at least in America, remains a field dominated by white males. A variety of evidence shows that many underrepresented groups, such as women and domestic students of color, are often motivated by course work that includes a clear societal benefit. The Humanitarian Free and Open Source Software (HFOSS) approach suggests that working on FOSS projects that have humanitarian benefits provides such motivation. Unfortunately, adding new themes and topics to courses can be difficult. CS2, in particular, often feels packed enough that it's hard to envision adding something else. And, while HFOSS is attractive, it's sometimes hard for the particular needs of a project to help students develop course-specific knowledge (about data structures and algorithms).I've recently experimented with an idea that I call "HFOSS-lite". Rather than students contributing directly to an HFOSS project, they use an HFOSS project as a source of data for their data structures and algorithms. The Ushahidi crowdmapping platform has proven especially useful. Students can contribute data to Ushahidi sites and even build their own sites. The data can be used in a variety of exercises, from simple searching to sorting algorithms in which they use different criteria (not just alphabetical or by time, but also by distance from a location and a variety of hybrid approaches) and beyond. And, because they are using the HFOSS software, they think about societal impact.

This Research to Practice Work in Progress paper develops an adaptive learning module aimed at enriching data structures and algorithms courses (CS2/DS) with introductory parallel computing. We emphasize exploitable shared-memory parallelism with the intention of teaching students to decompose a problem or its underlying big data structure into parts that can execute effectively in many- or multi-core processes. The module can set up conditional mastery paths and differentiate assignments for individual students automatically. The adaptive learning reflects the student-directed learning by doing and so fits naturally into the conventional CS2/DS courses. We conducted a 50-minute learning session in an adaptive learning CS2/DS class for a group of 56 students in the Fall 2019 semester. The experimental results, from two surveys executed before and after the session, was successful in engaging students, instigating students' interest in parallel computing, and improving the students' awareness and appreciation. The module can be extended to support other parallel computing concepts, such as critical section, race condition, and multi-thread synchronization and cooperation techniques. As a side benefit, we would like to show that adaptive learning prepares students, gets students to engage, and enhances their performance.

Crib sheets and exam performance in a data structures course

In this paper, we study the relationship between the use of "crib sheets" or "cheat sheets" and performance on in-class exams. Our extensive survey of the existing literature shows that it is not decisive on the questions of when or whether crib sheets actually help students to either perform better on an exam or better learn the material. We report on our own detailed analysis for a body of crib sheets created for the final exam in a junior-level data structures and algorithms course. We wanted to determine whether there is any feature of the crib sheets that correlates to good exam scores. Exam performance was compared against a number of potential indicators for quality in a crib sheet. We have found that students performed significantly better on questions at the comprehension level of Bloom's taxonomy when their crib sheet contained good information on the topic, while performance on questions at higher levels of the taxonomy did not show correlation to crib sheet contents. We have also seen that students at certain levels of performance on the final exam (specifically, medium-to-high performance) did relatively better on certain questions than other students at that performance level when they had good coverage of that question's topic on their crib sheet.
