Peer assessment, as a form of collaborative learning, can engage students in active learning and improve their learning gains. However, current teaching platforms and programming environments provide little support to integrate peer assessment for in-class programming exercises. We identified challenges in conducting such exercises and adopting peer assessment through formative interviews with instructors of introductory programming courses. To address these challenges, we introduce PuzzleMe, a tool to help Computer Science instructors to conduct engaging in-class programming exercises. PuzzleMe leverages peer assessment to support a collaboration model where students provide timely feedback on their peers' work. We propose two assessment techniques tailored to in-class programming exercises: live peer testing and live peer code review. Live peer testing can improve students' code robustness by allowing them to create and share lightweight tests with peers. Live peer code review can improve code understanding by intelligently grouping students to maximize meaningful code reviews. A two-week deployment study revealed that PuzzleMe encourages students to write useful test cases, identify code problems, correct misunderstandings, and learn a diverse set of problem-solving approaches from peers.

PeerPresents: A Web-Based System for In-Class Peer Feedback during Student Presentations
Peer feedback systems enable students to get feedback without substantially burdening the instructor. However, current systems typically ask students to provide feedback after class; this introduces challenges for ensuring relevant, timely, diverse, and sufficient amounts of feedback, and reduces time available for student reflection. This paper explores the current landscape of peer feedback tools and introduces a novel system for in-class peer review called PeerPresents where students can quickly exchange feed-back on projects without being burdened by additional work outside of class. Through an exploratory study with Google docs and a preliminary evaluation of PeerPresents, we find students can receive immediate, copious, and diverse peer feedback through a structured in-class activity. Students also described the feedback they received as helpful and reported that they gave more feedback than without using the system. These early results demonstrate the potential benefits of in-class peer feedback systems.

Peer feedback is a central activity for project-based design education. The prevalence of devices carried by students and the emergence of novel peer feedback systems enables the possibility of collecting and sharing feedback immediately between students during class. However, pen and paper is thought to be more familiar, less distracting for students, and easier for instructors to implement and manage. To evaluate the efficacy of in-class digital feedback systems, we conducted a within-subjects study with 73 students during two weeks of a game design course. After short student presentations, while instructors provided verbal feedback, peers provided feedback either on paper or through a device. The study found that both methods yielded comments of similar quality and quantity, but the digital approach provided additional ways for students to participate and required less effort from the instructors. While both methods produced similar behaviors, students held inaccurate perceptions about their behavior with each method. We discuss design implications for technologies to support in-class feedback exchange.more » « less

This letter introduces a novel method for the stability analysis of positive feedback systems with a class of fully connected feedforward neural networks (FFNN) controllers. By establishing sector bounds for fully connected FFNNs without biases, we present a stability theorem that demonstrates the global exponential stability of linear systems under fully connected FFNN control. Utilizing principles from positive Lur’e systems and the positive Aizerman conjecture, our approach effectively addresses the challenge of ensuring stability in highly nonlinear systems. The crux of our method lies in maintaining sector bounds that preserve the positivity and Hurwitz property of the overall Lur’e system. We showcase the practical applicability of our methodology through its implementation in a linear system managed by a FFNN trained on output feedback controller data, highlighting its potential for enhancing stability in dynamic systems.more » « less

Student Experiences With Peer Review and Revision for Writing-to-Learn in a Chemistry Course ContextPeer review is useful for providing students with formative feedback, yet it is used less frequently in STEM classrooms and for supporting writing-to-learn (WTL). While research indicates the benefits of incorporating peer review into classrooms, less research is focused on students’ perceptions thereof. Such research is important as it speaks to the mechanisms whereby peer review can support learning. This study examines students’ self-reported approaches to and perceptions of peer review and revision associated with WTL assignments implemented in an organic chemistry course. Students responded to a survey covering how they approached peer review and revision and the benefits they perceived from participating in each. Findings indicate that the assignment materials guided students’ approaches during both peer review and revision. Furthermore, students described various ways both receiving feedback from their peers and reading their peers’ drafts were beneficial, but primarily connected their revisions to receiving feedback.more » « less

East, Martin; Slomp, David (Ed.)Studies examining peer review demonstrate that students can learn from giving feedback to and receiving feedback from their peers, especially when they utilize information gained from the review process to revise. However, much of the research on peer review is situated within the literature regarding how students learn to write. With an increasing use of writing-to-learn in STEM classrooms, it is important to study how students engage in peer review for these types of writing assignments. This study sought to better understand how peer review and revision can support student learning for writing-to-learn specifically, using the lenses of cognitive perspectives of writing and engagement with written corrective feedback. Using a case study approach, we provide a detailed analysis of six students’ written artifacts in response to a writing-to-learn assignment that incorporated peer review and revision implemented in an organic chemistry course. Students demonstrated a range in the types of revisions they made and the extent to which the peer review process informed their revisions. Additionally, students exhibited surface, midlevel, and active engagement with the peer review and revision process. Considering the different engagement levels can inform how we frame peer review to students when using it as an instructional practice.more » « less
