The College of Engineering, Computer Science, and Technology (ECST) at California State University, Los Angles, an Hispanic Serving Institution (HSI) with over 60% Hispanic students, is committed to improving graduation rates through the Grad initiative 2025 (the California State University’s initiative to increase graduation rates for all CSU students while eliminating achievement gaps). The majority of our students are under-represented minorities, low-income, Pell-eligible and first generation. Currently, one quarter of the students leaving the major before the second year. Many that “survive” the first two years of math and science do not develop the knowledge and the skills that are needed to succeed in upper division engineering courses, leading to more students unable to finish their engineering majors. Three years ago, we launched a pilot program for the First-Year Experience at ECST (FYrE@ECST) for incoming freshmen. The program focuses on providing academic support for math and physics courses while introducing students to the college community, and comprises a summer bridge program, a hands-on introductory course, cohorted math and science sections, and staff and faculty mentoring. Academic support is provided through peer-led supplemental instruction (SI) workshops. The workshops have led to a significant improvement in student performance in Math, but have had no significant impact in the student performance in physics. Our hypothesis is that students, in addition to having limited understanding of calculus, struggle to understand the fundamental principles of physics and thus cannot apply their knowledge of math to theories in physics to solve problems. This work-in-progress paper describes an inquiry-based hands-on pre-physics course for first-year students as part of the FYrE@ECST program. The course is intended to prepare students for the calculus-based mechanics course in physics and covers about half of the competencies of a classical mechanics course, with focuses on the fundamental concepts of mechanics (i.e. Newton’s Laws, Types of forces, vectors, free-body diagrams, position, velocity and acceleration). Equations are only introduced in the second half of the semester, while the first half is directed to help students develop a deep understanding of these fundamental concepts. During classes, students run simple experiments, watch segments of movies and cartoons and are asked questions (written and orally) which can guide them to think intuitively and critically. A think-pair-share mode of instruction is implemented to promote inquiry and discussion. Students work in groups of five to discuss and solve problems, carry out experiments to better understand processes and systems, and share what they learned with the whole class. The paper presents preliminary results on student achievement.

Introduction to Quantum Computing for Everyone: Experience Report
Quantum computing presents a paradigmatic shift in the field of computation, in which unintuitive properties of quantum mechanics can be harnessed to change the way we approach a wide range of problems. However, due to the mathematics and physics perspective through which quantum computing is traditionally presented, most resources are inaccessible to many undergraduate students, let alone the general public. It is thus imperative to develop resources and best-practices for quantum computing instruction accessible to students at all levels. In this paper, we describe the development and results of our Massive Open Online Course (MOOC) "Introduction to Quantum Computing for Everyone." This course presents an introduction to quantum computing with few technical prerequisites. In the first half of the course, quantum computing concepts are introduced with a unique, purely visual representation, allowing students to develop conceptual understanding without the burden of learning new mathematical notation. In the second half, students are taught the formal notation for concepts and objects already introduced, reinforcing student understanding of these concepts and providing an applicable context for the technical material. Most notably, we find that introducing the math content in the curriculum's second stage led to no drops in engagement or student performance, suggesting that our curriculum's spiral structure eased the technical burden.

Quantum computing (QC) is an emerging field at the intersection of computer science and physics. Harnessing the power of quantum mechanics, QC is expected to solve otherwise intractable problems significantly faster, including in encryption, drug development, and optimization. High-quality and accessible QC resources are needed to help students develop the critical skills and confidence to contribute to the field. However, existing programs are often aimed at college students with an advanced mathematics or physics background, shutting out potential innovators. To make quantum learning resources for a broad, young audience, we designed Qupcakery, a puzzle game that introduces players to several core QC concepts: quantum gates, superposition, and measurement. We present preliminary testing results with both middle school and high school students. Using in-game data, observation notes, and focus group interviews, we identify student challenges and report student feedback. Overall, the game is at an appropriate level for high school students but middle school students need more levels to practice when new concepts are introduced.more » « less

The quantum computing curriculum developed in the Freshman Research Initiative at The University of Texas at Austin caters to students who have not yet studied advanced math and science. We lower the barrier to entry by simplifying notation and teaching through application of the concepts, only covering math methods as they become necessary. Physical motivation and simulation connect with students, and embedded examples and practice problems help cement their understanding. Through learning to program in Python and completing creative technical projects, students gain valuable, transferable skills while exploring quantum information and computing.more » « less

One expected outcome of physics instruction is for students to be capable of relating physical concepts to multiple mathematical representations. In quantum mechanics (QM), students are asked to work across multiple symbolic notations, including some they have not previously encountered. To investigate student understanding of the relationships between expressions used in these various notations, a survey was developed and distributed to students at six different institutions. All of the courses studied were structured as “spins-first,” in which the course begins with spin-1/2 systems and Dirac notation before transitioning to include continuous systems and wave function notation. Network analysis techniques such as community detection methods were used to investigate conceptual connections between commonly used expressions in upper-division QM courses. Our findings suggest that, for spins-first students, Dirac bras and kets share a stronger identity with vectorlike concepts than are associated with quantum state or wave function concepts. This work represents a novel way of using well-developed network analysis techniques and suggests such techniques could be used for other purposes as well.more » « less

null (Ed.)Engineering graduates need a deep understanding of key concepts in addition to technical skills to be successful in the workforce. However, traditional methods of instruction (e.g., lecture) do not foster deep conceptual understanding and make it challenging for students to learn the technical skills, (e.g., professional modeling software), that they need to know. This study builds on prior work to assess engineering students’ conceptual and procedural knowledge. The results provide an insight into how the use of authentic online learning modules influence engineering students’ conceptual knowledge and procedural skills. We designed online active learning modules to support and deepen undergraduate students’ understanding of key concepts in hydrology and water resources engineering (e.g., watershed delineation, rainfall-runoff processes, design storms), as well as their technical skills (e.g., obtaining and interpreting relevant information for a watershed, proficiency using HEC-HMS and HEC-RAS modeling tools). These modules integrated instructional content, real data, and modeling resources to support students’ solving of complex, authentic problems. The purpose of our study was to examine changes in students’ self-reported understanding of concepts and skills after completing these modules. The participants in this study were 32 undergraduate students at a southern U.S. university in a civil engineering senior design course who were assigned four of these active learning modules over the course of one semester to be completed outside of class time. Participants completed the Student Assessment of Learning Gains (SALG) survey immediately before starting the first module (time 1) and after completing the last module (time 2). The SALG is a modifiable survey meant to be specific to the learning tasks that are the focus of instruction. We created versions of the SALG for each module, which asked students to self-report their understanding of concepts and ability to implement skills that are the focus of each module. We calculated learning gains by examining differences in students’ self-reported understanding of concepts and skills from time 1 to time 2. Responses were analyzed using eight paired samples t-tests (two for each module used, concepts and skills). The analyses suggested that students reported gains in both conceptual knowledge and procedural skills. The data also indicated that the students’ self-reported gain in skills was greater than their gain in concepts. This study provides support for enhancing student learning in undergraduate hydrology and water resources engineering courses by connecting conceptual knowledge and procedural skills to complex, real-world problems.more » « less
