1. gPortfolios: A pragmatic approach to online asynchronous assignments

   Hickey, D. T. ( April 2020 , Information and learning science)

   Purpose: We gathered examples from our extended collaboration to move educators move online while avoiding synchronous meetings. “gPortfolios” are public (to the class) pages where students write responses to carefully constructed engagement routines. Students then discuss their work with instructors and peers in threaded comments. gPortfolios usually include engagement reflections, formative self-assessments, and automated quizzes. These assessments support and document learning while avoiding instructor “burnout” from grading. gPortfolios can be implemented using Google Docs and Forms or any learning management system. Methodology. We report practical insights gained from design-based implementation research. This research explored the late Randi Engle’s principles for productive disciplinary engagement and expansive framing. Engle used current theories of learning to foster student discussions that were both authentic to the academic discipline at hand and productive for learning. This research also used new approaches to assessment to support Engle’s principles. This resulted in a comprehensive approach to online instruction and assessment that is effective and efficient for both students and teachers. Findings. Our approach “frames” (i.e., contextualizes) online engagement using each learners’ own experiences, perspectives, and goals. Writing this revealed how this was different in different courses. Secondary biology students framed each assignment independently. Secondary English and historymore »students framed assignments as elements of a personalized capstone presentation; the history students further used a self-selected “historical theme.” Graduate students framed each assignment in an educational assessment course using a real or imagined curricular aim and context. Originality. Engle’s ideas have yet to be widely taken up in online education.« less
2. Low-Barrier Strategies to Increase Student-Centered Learning Low-Barrier Strategies to Increase Student-Centered Learning

   Friend, Nicole Erin Woodcock ( July 2021 , ASEE annual conference exposition proceedings)

   Evidence has shown that facilitating student-centered learning (SCL) in STEM classrooms enhances student learning and satisfaction [1]–[3]. However, despite increased support from educational and government bodies to incorporate SCL practices [1], minimal changes have been made in undergraduate STEM curriculum [4]. Faculty often teach as they were taught, relying heavily on traditional lecture-based teaching to disseminate knowledge [4]. Though some faculty express the desire to improve their teaching strategies, they feel limited by a lack of time, training, and incentives [4], [5]. To maximize student learning while minimizing instructor effort to change content, courses can be designed to incorporate simpler, less time-consuming SCL strategies that still have a positive impact on student experience. In this paper, we present one example of utilizing a variety of simple SCL strategies throughout the design and implementation of a 4-week long module. This module focused on introductory tissue engineering concepts and was designed to help students learn foundational knowledge within the field as well as develop critical technical skills. Further, the module sought to develop important professional skills such as problem-solving, teamwork, and communication. During module design and implementation, evidence-based SCL teaching strategies were applied to ensure students developed important knowledge and skills withinmore »the short timeframe. Lectures featured discussion-based active learning exercises to encourage student engagement and peer collaboration [6]–[8]. The module was designed using a situated perspective, acknowledging that knowing is inseparable from doing [9], and therefore each week, the material taught in the two lecture sessions was directly applied to that week’s lab to reinforce students’ conceptual knowledge through hands-on activities and experimental outcomes. Additionally, the majority of assignments served as formative assessments to motivate student performance while providing instructors with feedback to identify misconceptions and make real-time module improvements [10]–[12]. Students anonymously responded to pre- and post-module surveys, which focused on topics such as student motivation for enrolling in the module, module expectations, and prior experience. Students were also surveyed for student satisfaction, learning gains, and graduate student teaching team (GSTT) performance. Data suggests a high level of student satisfaction, as most students’ expectations were met, and often exceeded. Students reported developing a deeper understanding of the field of tissue engineering and learning many of the targeted basic lab skills. In addition to hands-on skills, students gained confidence to participate in research and an appreciation for interacting with and learning from peers. Finally, responses with respect to GSTT performance indicated a perceived emphasis on a learner-centered and knowledge/community-centered approaches over assessment-centeredness [13]. Overall, student feedback indicated that SCL teaching strategies can enhance student learning outcomes and experience, even over the short timeframe of this module. Student recommendations for module improvement focused primarily on modifying the lecture content and laboratory component of the module, and not on changing the teaching strategies employed. The success of this module exemplifies how instructors can implement similar strategies to increase student engagement and encourage in-depth discussions without drastically increasing instructor effort to re-format course content.

3. Collective Development of Large Scale Data Science Products via Modularized Assignments: An Experience Report

   Bhavya, Bhavya ; Boughoula, Assma ; Green, Aaron ; Zhai, ChengXiang ( February 2020 , Proceedings of the 51st ACM Technical Symposium on Computer Science Education)

   Many universities are offering data science (DS) courses to fulfill the growing demands for skilled DS practitioners. Assignments and projects are essential parts of the DS curriculum as they enable students to gain hands-on experience in real-world DS tasks. However, most current assignments and projects are lacking in at least one of two ways: 1) they do not comprehensively teach all the steps involved in the complete workflow of DS projects; 2) students work on separate problems individually or in small teams, limiting the scale and impact of their solutions. To overcome these limitations, we envision novel synergistic modular assignments where a large number of students work collectively on all the tasks required to develop a large-scale DS product. The resulting product can be continuously improved with students' contributions every semester. We report our experience with developing and deploying such an assignment in an Information Retrieval course. Through the assignment, students collectively developed a search engine for finding expert faculty specializing in a given field. This shows the utility of such assignments both for teaching useful DS skills and driving innovation and research. We share useful lessons for other instructors to adopt similar assignments for their DS courses.

   Computing theory is often perceived as challenging by students, and verifying the correctness of a student’s automaton or grammar is time-consuming for instructors. Aiming to provide benefits to both students and instructors, we designed an automated feedback tool for assignments where students construct automata or grammars. Our tool, built as an extension to the widely popular JFLAP software, determines if a submission is correct, and for incorrect submissions it provides a “witness” string demonstrating the incorrectness. We studied the usage and benefits of our tool in two terms, Fall 2019 and Spring 2021. Each term, students in one section of the Introduction to Computer Science Theory course were required to use our tool for sample homework questions targeting DFAs, NFAs, RegExs, CFGs, and PDAs. In Fall 2019, this was a regular section of the course.We also collected comparison data from another section that did not use our tool but had the same instructor and homework assignments. In Spring 2021, a smaller honors section provided the perspective from this demographic. Overall, students who used the tool reported that it helped them to not only solve the homework questions (and they performed better than the comparison group) but also to better understandmore »the underlying theory concept. They were engaged with the tool: almost all persisted with their attempts until their submission was correct despite not being able to random walk to a solution. This indicates that witness feedback, a succinct explanation of incorrectness, is effective. Additionally, it assisted instructors with assignment grading.« less
5. Improving conceptual understanding of gas behavior through the use of screencasts and simulations

   Abstract Background Engagement with particle-level simulations can help students visualize the motion and interactions of gas particles, thus helping them develop a more scientifically accurate mental model. Such engagement outside of class prior to formal instruction can help meet the needs of students from diverse backgrounds and provide instructors with a common experience upon which to build with further instruction. Yet, even with well-designed scaffolds, students may not attend to the most salient aspects of the simulation. In this case, a screencast where an instructor provides narrated use of the simulation and points students towards the important observations may provide additional benefits. This study, which is part of the larger ChemSims project, investigates the use of simulations and screencasts to support students’ developing understanding of gas properties by examining student learning gains. Results This study indicates that both students manipulating the simulation on their own and those observing a screencast exhibited significant learning gains from pre- to post-assessment. However, students who observed the screencast were more than twice as likely to transition from a macroscopic explanation to a particle-level explanation of gas behavior in answering matched pre- and post-test questions. Eye-tracking studies indicated very similar viewing and usage patterns formore »both groups of students overall, including when using the simulation to answer follow-up questions. Conclusion Significant learning gains by both groups across all learning objectives indicate that either scaffolded screencast or simulation assignments can be used to support student understanding of gas particle behavior and serve as a first experience upon which to build subsequent instruction. There is some indication that the initial use of the screencast may better help students build correct mental models of gas particle behavior. Further, for this simulation, watching the instructor manipulate the simulation in the screencast allowed students to subsequently use the simulation on their own at a level comparable to those students who had manipulated the simulation on their own throughout the assignment, suggesting that the screencast students were not disadvantaged by not initially manipulating the simulation on their own.« less
