Abstract Knowledge of quantum mechanical systems is becoming more important for many science and engineering students who are looking to join the emerging quantum workforce. To better prepare a wide range of students for these careers, we must seek to develop new tools to enhance our education in quantum topics. We present initial studies on the use of one of these such tools, Quantum Composer, a 1D quantum simulation and visualization tool developed for education and research purposes. In particular, we conducted five think-aloud interviews with students who worked through an exercise using Quantum Composer that focused on the statics and dynamics of quantum states in a single harmonic well system. Our results show that Quantum Composer helps students to obtain the correct answers to the questions posed, but additional support is needed to facilitate the development of student reasoning behind these answers. We also show that students are able to focus only on the relevant features of Quantum Composer to achieve the task.

Investigating student use of a flexible tool for simulating and visualizing quantum mechanics
As education researchers gain a broader understanding of how students learn quantum mechanics, new pedagogical and technical resources are being developed to facilitate student learning. To further research-based knowledge of student learning of quantum mechanics, we present a study on the use of Quantum Composer, a flexible, flow-based tool for the exploration and simulation of quantum mechanical systems in one dimension. To explore Composer’s impact on students’ knowledge of quantum mechanics, we carried out think-aloud interviews where students worked through an exercise exploring the statics and time-dynamics of quantum states in single and double harmonic well potentials. Student Outcomes are then cross-coded with their observed Interactions with Composer. We find that defined Outcomes of Recollection, Reinforcement and Discovery happen most often when students are using the Composer tools that allow them to visualize quantum states, simulate their time dynamics, and change parameters repeatedly in order to understand how systems are represented in both the static and dynamic cases.

Abstract Research-validated multiple-choice questions comprise an easy-to-implement instructional tool that serves to scaffold student learning and formatively assess students’ knowledge. We present findings from the implementation, in consecutive years, of a research-validated multiple-choice question sequence on measurement uncertainty as it applies to two-state quantum systems. This study was conducted in an advanced undergraduate quantum mechanics course, in online and in-person learning environments for consecutive years. Student learning was assessed after receiving traditional lecture-based instruction in relevant concepts, and their performance was compared with that of a similar assessment given after engaging with the multiple-choice question sequence. We analyze and discuss the similar and differing trends observed in the two modes of instruction.more » « less

This project supports the success of undergraduate engineering students through coordinated design of curricula across STEM course sequences. The Analysis, Design, Development, Implementation, Evaluation (ADDIE) framework and backward design are being used to develop guides for instructors to align learning outcomes, assessments, and instructional materials in a physics – engineering mechanics course sequence. The approach relies on the analysis of student learning outcomes in each course, identification of interdependent learning outcomes, and development of skills hierarchies in the form of visual learning maps. The learning maps are used to illustrate the knowledge required and built upon throughout the course sequence. This study will assess the effectiveness of a course redesign intervention, which uses visual learning maps and backward design concepts, to guide instructors within a common course sequence to align learning outcomes and assessments. If successful, the intervention is expected to improve students’ primary learning and knowledge retention, as well as persistence and success in the degree. The study will compare academic performance among Mechanical Engineering B.S., Environmental Engineering B.S., and Civil Engineering B.S. students who begin a Physics for Engineers – Statics – Dynamics course prior to the intervention (control) and after the intervention (treatment). During control and treatment terms, students’ primary learning in individual courses will be assessed using established concept inventories. Retention of knowledge from pre-requisite courses will be tracked using pre-identified problem sets (quizzes, exams) specifically associated with interdependent learning outcomes in the Statics and Dynamics courses. Students’ primary learning and knowledge retention in the sequence will be related to longer term student success outcomes, including retention and graduation. The poster will show the results of the research team’s first year of work, including an analysis of current course materials, learning maps for each course, identification of interdependent learning outcomes, example guiding materials and templates for instructors, and preliminary student performance data from the control cohort.more » « less

Abstract Research-validated multiple-choice questions comprise an easy-to-implement instructional tool for scaffolding student learning and providing formative assessment of students’ knowledge. We present findings from the implementation of a research-validated multiple-choice question sequence on the basics of two-state quantum systems, including inner products, outer products, translation between Dirac notation and matrix representation in a particular basis, and change of basis. This study was conducted in an advanced undergraduate quantum mechanics course, in both online and in-person learning environments, across three years. For each cohort, students had their learning assessed after traditional lecture-based instruction in relevant concepts before engaging with the multiple-choice question sequence. Their performance was evaluated again afterward with a similar assessment and compared to their earlier performance. We analyze, compare, and discuss the trends observed in the three implementations.more » « less

Mills, Caitlin; Alexandron, Giora; Taibi, Davide; Lo_Bosco, Giosuè; Paquette, Luc (Ed.)Research on epistemic emotions has often focused on how students transition between affective states (e.g., affect dynamics). More recently, studies have examined the properties of cases where a student remains in the same affective state over time, finding that the duration of a student's affective state is important for multiple learning outcomes. However, the likelihood of remaining in a given affective state has not been widely studied across different methods or systems. Additionally, the role of motivational factors in the persistence or decay of affective states remains underexplored. This study builds on two prior investigations into the exponential decay of epistemic emotions, expanding the analysis of affective chronometry by incorporating two detection methods based on student self-reports and trained observer labels in a game-based learning environment. We also examine the relationship between motivational measures and affective decay. Our findings indicate that boredom exhibits the slowest decay across both detection methods, while confusion is the least persistent. Furthermore, we found that higher situational interest and self-efficacy are associated with greater persistence in engaged concentration, as identified by both detection methods. This work provides novel insights into how motivational factors shape affective chronometry, contributing to a deeper understanding of the temporal dynamics of epistemic emotions.more » « less
