Title: Development of a Safe, Scalable, Course-Based Undergraduate Research Experience for Analytical Chemistry: The μCURE Project
Course-based undergraduate research experiences (CUREs) can have many positive effects on students’ learning and sense of self-efficacy. We have developed a networked CURE between four different institutions designed for courses in analytical chemistry that focuses on the process of adapting published solution-phase colorimetric assays into microfluidic paper analytical devices (μPAD) assays. We used a backward design process to develop 5 scaffolded learning outcomes: (1) identify and assess relevant literature sources, (2) propose a viable experimental plan to answer a well-defined scientific question based on literature information and experimental results, (3) apply appropriate methods of data analysis to interpret experimental results, (4) evaluate multiple pieces of experimental data to support conclusions, and (5) contribute to a team by working collaboratively toward common goals. Students begin the project by completing a literature search assignment to identify a published colorimetric assay they plan to adapt. They then write a proposal which identifies their analyte, sample of interest, and the figures of merit required for successful sample analysis using their μPAD. During the 3–5 weeks of laboratory work, students conduct their experiments, and each week evaluate the significance of their data and propose an experimental plan for the upcoming week. At the end of the μCURE project, students present their results in a joint, asynchronous poster session. Student artifacts are assessed for evidence of particular skills using rubrics from the Enhancing Learning by Improving Process Skills in STEM (ELIPSS) Project. Scores on the rubrics indicate partial to full attainment of each of the five learning outcomes  more » « less

    Participation in an archaeological field school is the entry point to a professional career in the discipline. Despite the importance of field schools, few scholars have investigated achieved student-learning outcomes or lasting impacts on students from participation in archaeological field research. We report on the educational design, learning objectives, and results of three years of formative and summative assessments for an interdisciplinary, archaeology and ecology research program for undergraduate students. Our learning objectives include promoting scientific literacy and communication, critical thinking and STEM skills, and capacities in archaeological and ecological interdisciplinarity. Using developed rubrics that account for both critical thinking and STEM understanding, self-administered competency surveys, and program-developed items, we found significant gains in nearly all learning objectives. Students demonstrated growth in program specific content, perceived abilities in their scientific and discipline specific skills, critical thinking skills, and scientific communication skills. These educational outcomes and assessment tools have implications for how we design and evaluate field learning in archaeology and may be applied to field school instruction.

  2. This paper presents the design and analysis of a pilot problem set deployed to engineering students to assess their retention of physics knowledge at the start of a statics course. The problem set was developed using the NSF-IUSE (grant #2315492) Learning Map project (LMap) and piloted in the spring and fall of 2024. The LMap process is rooted in the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model [1] and Backward Design [2,3], extending these principles to course sequences to align learning outcomes, assessments, and instructional practices. The primary motivation for this problem set (Statics Knowledge Inventory, SKI) was to evaluate students' understanding and retention of physics concepts at the beginning of a statics course. The SKI includes a combination of multiple-choice questions (MCQ) and procedural problems, filling a gap in widely-used concept inventories for physics and statics, such as the Force Concept Inventory (FCI) and Statics Concept Inventory (SCI), which evaluate learning gains within a course, rather than knowledge retention across courses. Using the LMap analysis and instructor consultations, we identified overlapping concepts and topics between Physics and Statics courses, referred to here as “interdependent learning outcomes” (ILOs). The problem set includes 15 questions—eight MCQs and seven procedural problems. Unlike most concept inventories, procedural problems were added to provide insight into students’ problem-solving approach and conceptual understanding. These problems require students to perform calculations, demonstrate their work, and assess their conceptual understanding of key topics, and allow the instructors to assess essential prerequisite skills like drawing free-body diagrams (FBDs), computing forces and moments, and performing basic vector calculation and unit conversions. Problems were selected and adapted from physics and statics textbooks, supplemented by instructor-designed questions to ensure full coverage of the ILOs. We used the revised 2D Bloom’s Taxonomy [4] and a 3D representation of it [5] to classify each problem within a 6x4 matrix (six cognitive processes x four knowledge dimensions). This classification provided instructors and students with a clear understanding of the cognitive level required for each problem. Additionally, we measured students’ perceived confidence and difficulty in each problem using two questions on a 3-point Likert scale. The first iteration of the problem set was administered to 19 students in the spring 2024 statics course. After analyzing their performance, we identified areas for improvement and revised the problem set, removing repetitive MCQs and restructuring the procedural problems into scaffolded, multi-part questions with associated rubrics for evaluation. The revised version, consisting of five MCQs and six procedural problems, was deployed to 136 students in the fall 2024 statics course. A randomly selected subset of student answers from the second iteration was graded and analyzed to compare with the first. This analysis will inform future efforts to evaluate knowledge retention and transfer in key skills across sequential courses. In collaboration with research teams developing concept inventories for mechanics courses, we aim to integrate these procedural problems into future inventories.

  3. Asynchronous online courses are popular because they offer benefits to both students and instructors. Students benefit from the convenience, flexibility, affordability, freedom of geography, and access to information. Instructors and institutions benefit by having a broad geographical reach, scalability, and cost-savings of no physical classroom. A challenge with asynchronous online courses is providing students with engaging, collaborative and interactive experiences. Here, we describe how an online poster symposium can be used as a unique educational experience and assessment tool in a large-enrollment (e.g., 500 students), asynchronous, natural science, general education (GE) course. The course, Introduction to Environmental Science (ENR2100), was delivered using distance education (DE) technology over a 15-week semester. In ENR2100 students learn a variety of topics including freshwater resources, surface water, aquifers, groundwater hydrology, ecohydrology, coastal and ocean circulation, drinking water, water purification, wastewater treatment, irrigation, urban and agricultural runoff, sediment and contaminant transport, water cycle, water policy, water pollution, and water quality. Here we present a is a long-term study that takes place from 2017 to 2022 (before and after COVID-19) and involved 5,625 students over 8 semesters. Scaffolding was used to break up the poster project into smaller, more manageable assignments, which students completed throughout the semester. Instructions, examples, how-to videos, book chapters and rubrics were used to accommodate Students’ different levels of knowledge. Poster assignments were designed to teach students how to find and critically evaluate sources of information, recognize the changing nature of scientific knowledge, methods, models and tools, understand the application of scientific data and technological developments, and evaluate the social and ethical implications of natural science discoveries. At the end of the semester students participated in an asynchronous online poster symposium. Each student delivered a 5-min poster presentation using an online learning management system and completed peer reviews of their classmates’ posters using a rubric. This poster project met the learning objectives of our natural science, general education course and taught students important written, visual and verbal communication skills. Students were surveyed to determine, which parts of the course were most effective for instruction and learning. Students ranked poster assignments first, followed closely by lectures videos. Approximately 87% of students were confident that they could produce a scientific poster in the future and 80% of students recommended virtual poster symposiums for online courses.

  4. ABSTRACT This is a cross institution project involving four Institutes of Technology in Ireland. The objective of this project is to assess the use of technology to enhance the assessment of laboratory sessions in Science and Health. In science, health and engineering, the laboratory sessions are at the core of the learning process for skill development. These laboratory sessions focus on the skills acquisition. The Irish Institute of Technology sector, in particular, develops these skills and considers them essential for ‘professionally ready’ graduates. In terms of student progression and retention, the assessment structure has been identified as having a significant impact on student engagement. The Technology Enhanced Assessment Methods (TEAM) project led by Dundalk Institute of Technology and partnering with Institute of Technology Sligo, Athlone Institute of Technology and Institute of Technology Carlow is exploring the potential offered by digital technologies to address these concerns. It aims to develop a framework for applying the principles of effective assessment and feedback to practical assessment. The TEAM project also aims to facilitate dialogue among stakeholders about what it is we want student to learn in laboratory sessions and how our assessment can facilitate this. A peer network of discipline-specific academics and students in the Science and Health field has been established across all four Institutes. As the network focuses on authentic skills assessment in all core modules, including physics and chemistry, the best practice from this project will inform future assessment procedures across laboratory sessions and may be considered for application within a Science and Materials Engineering context. Assessing the skills acquired in this environment takes many forms. Using student and stakeholder feedback along with an extensive literature review of the area, the team identified key technologies that cut across science and health disciplines, with the potential to influence and enable the learning process. The emphasis was on developing a powerful learning environment approach to enable students to deepen their learning through engagement with the process. The areas identified are: (i) Pre-practical preparation (videos and quizzes), (ii) Electronic laboratory notebooks and ePortfolios, (iii) Digital Feedback technologies and (iv) Rubrics). This paper describes the student experience and perceptions of the adoption of digital technology in science practical assessments. It also describes the process involved in setting up the pilot structure and it presents the initial results from the student survey.

  5. This innovative practice work in progress paper presents a systematic approach for screening and aligning service-learning projects that maximize student learning outcomes. We introduce a feasibility assessment model with criteria evaluated through a standardized rubric that guides instructors to critically assess the project fit to help in proactively identifying risks to student outcomes. The rubric serves a dual purpose: guiding the assessment process and prompting discussions with potential project partners. These discussions elicit crucial details about the project scope, potential challenges, and other critical factors. This not only facilitates effective project selection but also allows for necessary adjustments to project parameters, significantly improving the chances of successful student completion. This work builds on the experience accumulated by CCSU's Software Engineering Studio which connects community project partners with teams of 4–5 seniors working on software development projects spanning one or several semesters. Since 2014, the Software Engineering Studio has facilitated over 65 distinct projects and engaged over 550 students. By capturing the lessons learned across a wide range of successful service-learning projects, we show the value of using a feasibility assessment model to evaluate potential projects based on criteria including alignment with course goals, student skill sets, workload manage-ability, educational engagement, and other considerations. The application of this model is illustrated with a case study, which demonstrates how this model helps instructors align projects with academic goals while considering scope, risks, and other critical elements. This example demonstrates how the model facilitates communication with project partners, identifies potential risks, and guides project adjustments to ensure a successful learning experience for students. The approach is transferable to other disciplines with adaptations for project types and student skills. This work contributes to the field of service learning by offering a practical framework for integrating valuable real-world projects into the curriculum while prioritizing student learning outcomes.
