An Exploratory Study of Student Perceptions of Ungrading in Upper-Level Psychology Courses

Background Ungrading is an innovative approach to assessment that relies on feedback rather than numerical grades to deprioritize (or remove) grades, but that has gone relatively unexplored in the psychology classroom. Objective The current study examined student perceptions of ungrading in three psychology courses. Method Using an inductive approach, we examined patterns and themes in student reflections across two time points (start and end of the semester) in three upper-division psychology courses. Results Students generally had positive impressions of ungrading, but stress around grade uncertainty was an area of concern. Conclusion Implementation of alternative grading methods has the potential for many benefits in the psychology classroom, but careful consideration is needed to overcome negative student perceptions. Teaching Implications Going gradeless is an intriguing option that may potentially impact student learning, engagement, motivation, mental health, and equity. This exploratory study offers insight into student perceptions of ungrading, which can help instructors who are considering this method.

The hardest-hit home run?

We present a problem to be assigned or done as an in-class activity in an upper-division undergraduate course on computational physics. The problem involves a home run hit by Mickey Mantle on May 22, 1963, which he famously called “the hardest ball I ever hit.” Is this home run truly one for the record books, or has it been eclipsed by players in the modern era? Modeling the trajectory of a baseball involves consideration of both wind resistance and the Magnus effect and is an interesting application of numerical solutions to ordinary differential equations. Ultimately, the answer is that Mantle would compare favorably to the most powerful batters currently playing, but to arrive at that conclusion we must reflect on the plausibility of results and sources of uncertainty.

Unpacking the Dynamics of Online Motivation: A Study of Short-Term Changes in Task Value and Cost Utilizing Multiple Change Analyses

Motivation is critical to student success in learning environments. However, changes in situation-specific motivation over time are rarely explored among online learners. Drawing from the Situated Expectancy Theory (SEVT), in the current study, I examined changes in situational task-specific task value and cost over the short term and tested the impact of these changes on achievement. I collected task value and cost over four time points from 68 students in an upper-division online Educational Psychology course. Grades on two discussion posts and one exam represented academic performance. I used multiple analytic techniques, scarcely used in the literature, to measure change across time, including task value-cost switching and group and individual-level task value-cost intensity. Group-level intensity analyses revealed task value and cost stability across most time point comparisons. However, individual-level analysis demonstrated variability in task value and cost across comparisons. There was no evidence of task value or cost switching. One significant increase in cost across tasks predicted academic performance in the subsequent assessment. The study highlights the importance of using various techniques to explore motivational changes among online learners and demonstrates the applicability of SEVT in online learning environments.

Mind the Gap: Investigating Disaggregated Student Performance in an Upper-Division Biochemistry Course Following Team-Based Learning.

Team-based learning (TBL) is a highly intense active learning pedagogy that uses a cycle of preclass preparation, formative assessment for readiness, mini-lectures, and complex team exercises. Consistent with the literature on active learning, prior research on TBL consistently shows its benefits for student outcomes as compared with previous lecture. However, little work has examined student outcomes disaggregated by demographic variable. We analyzed assessment and student demographic data (i.e., binary gender, racial/ethnic group, generational status) in three semesters of TBL in an upper-division biochemistry course to understand the degree to which performance could be predicted by student demographics. We use theoretical and empirical research from social psychology to hypothesize that the intense interpersonal interactions of TBL could activate psychological threats, the effects of which would be measurable as differences in student performance that correlate with demographic variables. Our regression analysis did not support this hypothesis. This null result invites a deeper discussion on how we measure the potential effects of active learning on student outcomes, particularly given how important it is to account for intersectional and invisible identities.

Immediate Versus Delayed Low-Stakes Questioning: Encouraging the Testing Effect Through Embedded Video Questions to Support Students’ Knowledge Outcomes, Self-Regulation, and Critical Thinking

AbstractIn light of the educational challenges brought about by the COVID-19 pandemic, there is a growing need to bolster online science teaching and learning by incorporating evidence-based pedagogical principles of Learning Experience Design (LXD). As a response to this, we conducted a quasi-experimental, design-based research study involving nN = 183 undergraduate students enrolled across two online classes in an upper-division course on Ecology and Evolutionary Biology at a large R1 public university. The study extended over a period of 10 weeks, during which half of the students encountered low-stakes questions immediately embedded within the video player, while the remaining half received the same low-stakes questions after viewing all the instructional videos within the unit. Consequently, this study experimentally manipulated the timing of the questions across the two class conditions. These questions functioned as opportunities for low-stakes content practice and retention, designed to encourage learners to experience testing effect and augment the formation of their conceptual understanding. Across both conditions, we assessed potential differences in total weekly quiz grades, page views, and course participation among students who encountered embedded video questions. We also assessed students’ self-report engagement, self-regulation, and critical thinking. On average, the outcomes indicated that learners exposed to immediate low-stakes questioning exhibited notably superior summative quiz scores, increased page views, and enhanced participation in the course. Additionally, those who experienced immediate questioning demonstrated heightened levels of online engagement, self-regulation, and critical thinking. Moreover, our analysis delved into the intricate interplay between treatment conditions, learners’ self-regulation, critical thinking, and quiz grades through a multiple regression model. Notably, the interaction between those in the immediate questioning condition and self-regulation emerged as a significant factor, suggesting that the influence of immediate questioning on quiz grades varies based on learners’ self-regulation abilities. Collectively, these findings highlight the substantial positive effects of immediate questioning of online video lectures on both academic performance and cognitive skills within an online learning context. This discussion delves into the potential implications for institutions to continually refine their approach in order to effectively promote successful online science teaching and learning, drawing from the foundations of pedagogical learning experience design paradigms and the testing effect model.

Network analysis of students’ conceptual understanding of mathematical expressions for probability in upper-division quantum mechanics

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.

Implementation of the photovoice methodology in a project-based upper-division physics course

Photovoice is a type of participatory action research in which individuals document their experiences through photography. Through the taking, captioning, and reflecting on photographs that they have taken, participants are able to affect change within their communities. Participants also take part in an interview or focus group about their photos at the end of the photovoice process in which they determine themes that appear in their photos, allowing them to participate in the research being done. We used the photovoice methodology in a small, project-based, upper-division, physics capstone course at the University of Colorado Boulder, in which students worked on an authentic industry project in partnership with a company in the quantum industry. As an example of the types of research results and benefits one could obtain using photovoice, we present a discussion of how we implemented the photovoice process within this course and present some of our results, including students’ experiences with the photovoice process. Photovoice may be particularly useful in understanding new, unique courses, as it allows students to co-create research that highlights ideas about the course that researchers would not know to ask about in more traditional research methodologies such as reflection questions.

Financial Literacy Simulation in Managerial Finance: Signing Up for a Mock 401(k)

Much evidence suggests a growing need for financial literacy as a prerequisite to a lifetime of financial well-being. And while it has been recommended that U.S. colleges and universities implement a mandatory financial literacy course (President’s Advisory Council on Financial Literacy, 2009; U.S. Financial Literacy and Education Commission, 2019), no such requirement has been imposed. Currently, only one quarter of college students report access to financial literacy education (Montalto et al, 2019). Guided by best practices and insights, this paper examines the opportunity for an upper-division core business course to support a focused, financial literacy learning opportunity for upper classmates by employing a simulated retirement plan enrollment. This work contributes to the body of work on financial literacy education and represents an efficient approach to providing relevant education to meet the growing financial literacy needs of college students.

Student definitions of ownership and perceived ways ownership influences writing in a biology laboratory class.

Laboratory courses offer a unique opportunity, and sometimes challenge, to engage students in projects where they can experience ownership and authentic science practices. An important science practice is writing, which can lead to increased learning about concepts and science communication. Experiencing a sense of ownership in research can lead to various student outcomes, such as increased motivation, greater interest in research, and higher retention in STEM fields. Although previous work has extracted aspects of ownership from students' descriptions of research experiences, studies have not examined directly how students define and perceive ownership. In addition, we do not have a clear idea of whether a sense of ownership is related to student attitudes toward scientific writing in a lab course setting. To better understand the relationship between ownership and writing directly from students' perspectives, we used analysis of student responses to surveys and interviews in an upper-division laboratory course. Using a grounded theory approach for the analysis of 167 survey responses and 9 interviews, we found that students have varying perceptions of project ownership, with the most frequent being opportunities to contribute ideas and shape the project (autonomy), doing the work, and leadership. Students largely perceived that increased ownership had positive influences on their writing, such as increased understanding and thinking, freedom in writing, and increased motivation. Learning about how students perceive ownership in the context of a lab course is useful for considering how lab course structure may support the development of a sense of ownership and may influence how we can engage students in meaningful writing practices.

Synthesis and Characterization of Superparamagnetic Iron Oxide Nanoparticles: A Series of Laboratory Experiments.

The following laboratory procedure provides students with hands-on experience in nanomaterial chemistry and characterization. This three-day protocol is easy to follow for undergraduates with basic chemistry or materials science backgrounds and is suitable for inclusion in upper-division courses in inorganic chemistry or materials science. Students use air-free chemistry procedures to synthesize and separate iron oxide magnetic nanoparticles and subsequently modify the nanoparticle surface by using a chemical stripping agent. The morphology and chemical composition of the nanoparticles are characterized using electron microscopy and dynamic light scattering measurements. Additionally, magnetic characterization of the particles is performed using an inexpensive open-source (3D-printed) magnetophotometer. Possible modifications to the synthesis procedure, including the incorporation of dopants to modify the magnetic response and alternative characterization techniques, are discussed. The three-day synthesis, purification, and characterization laboratory will prepare students with crucial skills for advanced technology industries such as semiconductor manufacturing, nanomedicine, and green chemistry.

Comparing learning outcomes of two collaborative activities on random genetic drift in an upper-division genetics course

Abstract Background Random genetic drift is a difficult concept for biology undergraduates to understand. Active learning activities in a collaborative setting have the potential to improve student learning outcomes compared to traditional lectures alone and have been shown to help foster success for underrepresented students. However, few activities in this content area have been evaluated for effectiveness in improving student outcomes using peer-reviewed instruments backed by evidence of their validity and reliability. Our aim in this study was to use the Genetic Drift Instrument (GeDI) to evaluate and compare student learning gains in an upper division genetics course in which two different genetic drift activities, a faculty-developed collaborative exercise and a commercially published lab tutorial, were administered in an active-learning classroom with students working in small groups. Methods The GeDI was administered in both pre- and post-testing in two semesters (n = 95 and 98 students), with the semesters differing in which activity was assigned. Instrument dimensionality, person and item fit, and reliability were evaluated using Rasch analysis. Hierarchical Linear Models (HLMs) with two-way interactions were fitted to assess whether being in a certain Intervention Type, Race/ethnicity, Gender, or First Generation Status affected learning gains. HLMs with three-way interactions were used to assess whether the activities benefited students of all backgrounds equivalently. Results We found that the GeDI demonstrated unidimensionality, with high item reliability and relatively low person reliability, consistent with previous studies. Both the faculty-developed activity and the commercially available lab tutorial were associated with significant learning gains on genetic drift concepts. Students in the SimBio group had higher learning gains but the difference in effect size was small. No significant differences in learning gains were found between students from different demographic groups, and both activities appeared to benefit students of different backgrounds equivalently. Conclusions The GeDI instrument could be improved by adding items that more consistently differentiate students of different ability levels, especially at high ability levels. The greater impact on learning gains in the SimBio group while statistically significant does not translate into actual meaningful differences in student understanding. While students of different background variables in the sample have equivalent learning gains and are benefitted equivalently by the different interventions, our interventions did not ameliorate inequities in genetic drift understanding as measured by the GeDI that were uncovered in pre-testing.

Exploring student reasoning in statistical mechanics: Identifying challenges in problem-solving groups

Statistical mechanics has received limited attention in physics education research and remains a relatively underrepresented topic even in research on upper-division physics courses. The purpose of this study was to explore potential challenges that physics students encounter when they solve statistical mechanics problems in groups. Adopting a grounded approach, we video recorded and analyzed nine small student groups engaging in collaborative problem solving on the topic. The analysis involved iterative thematic coding, which gave rise to ten emergent categories of challenges. These were later divided into two broad groupings: and . In the first grouping, we list seven identified categories related to the concepts of macrostates and microstates, distinguishable and indistinguishable particles, temperature, entropy, energy, equilibrium, heat bath, the Boltzmann distribution, and the partition function. In the second grouping, we list three categories related to the inappropriate application of common relations, difficulty managing tensions between calculated results and qualitative reasoning, and coming up with definitions of new and inconsistent concepts. Some of our findings are supported by existing research on the topic, and others are previously unreported. Based on our findings, we propose that future research should investigate the relations between the identified challenges on one hand, and students’ epistemological framing, reasoning, and use of multiple representations on the other. Finally, we suggest that teachers should spend time engaging students in a conceptual discussion of the central ideas of statistical mechanics, motivating the choice and pointing out limitations of commonly used toy models, and linking course content to real-world phenomena.

A Hands-On Collaboration-Ready Single- or Interdisciplinary Computational Exercise in Molecular Recognition and Drug Design

Molecular docking plays an increasingly necessary role in interdisciplinary research, particularly in modern drug design. Pharmaceutical companies compose a trillion dollar per year industry and the public is generally unaware of how beneficial pharmaceutics come to be. Despite this increasing relevance in contemporary research, docking and, by extension, computational science, have been under-represented in undergraduate education in the chemical, biochemical, and biophysical sciences. We describe herein how a multidisciplinary approach is used to design novel inhibitors of the butyrylcholinesterase enzyme (BChE), an upregulated protein in patients suffering from Alzheimer’s disease. Students will then be able to compare their designed inhibitors to known BChE inhibitors via molecular docking using this easily adapted hands-on computational laboratory exercise or at-home activity that provides users with a module in which to learn the fundamentals of computer-aided drug design. While being well suited for upper-division courses in biology/biochemistry and physics/physical chemistry, the accessibility of this module allows for its incorporation into college curricula as early as second-term organic chemistry. Highly portable freeware makes this an ideal learning tool by which to infuse single- or multidisciplinary drug design reasoning into college level curricula at no cost to the student or instructor.

Innovating Perception: A design-based learning group project for Sensation and Perception

ABSTRACT Sensation and Perception is an upper-division psychology course that typically focuses on foundational knowledge of sensory and perceptual systems. This study describes a design-based learning group project in Sensation and Perception that encouraged students to apply that foundational knowledge to real-world problems. Students were asked to devise, research, and conceptually design an innovation – such as a product or technology – that would help solve a problem faced by people with a particular sensory or perceptual difference (such as blindness). Students were guided through the design thinking process via 3 main phases: identifying the population and problem (empathizing and defining), using existing research to inform potential innovations (ideation), and designing a conceptual representation (prototyping). The project culminated in a product “pitch” and research paper. Survey data showed that students perceived the project to enhance their engagement with, application, and understanding of course material – benefits that were most prominent for first-generation students and people of colour. Furthermore, compared to students in previous quarters, students who completed this project achieved higher overall grades in the course. Overall, this study suggests that implementation of design-based learning group projects into courses like Sensation and Perception can enhance student learning and engagement, particularly for underrepresented students.

A spherical version of Feynman’s static field momentum example

The Feynman demonstration that electromagnetic field momentum is real—even for static fields—can be made more pedagogically useful by simplifying its geometry. Instead of Feynman’s disk with charged balls on its surface, this article uses the geometry of a hollow non-conducting sphere with uniform surface charge density. With only methods available in a typical upper-division electrodynamics course, the initial field angular momentum and the final mechanical angular momentum can then be calculated in closed form and shown to be equal.

Gendered Performance Gaps in an Upper-Division Biology Course: Academic, Demographic, Environmental, and Affective Factors.

Despite the existent gender parity in undergraduate biology degree attainment, gendered differences in outcomes are prevalent in introductory biology courses. Less is known about whether these disparities persist at the upper-division level, after most attrition is assumed to have occurred. Here, we report the consistent presence of gender equity gaps across 35 offerings (10 years) ofalarge-enrollment upper-division biology course at a research-intensive public university.Multilevel modeling showed that women's grades were lower than men's, regardless of prior GPA. These gender gaps were present even when controlling for students' race/ethnicity, socioeconomic status, first-generation college-going status, international status, and transfer status. Class size, gender representation in the classroom, and instructor gender did not significantly relate to course grades. Student questionnaires in a subset of offerings indicated gendered differences in course anxiety, science identity, and science self-efficacy, which correlated with grade outcomes. These results suggest that women experience differential outcomes in upper-division biology, which may negatively influence their persistence in STEM fields postgraduation. Our findings suggest that gender disparities are a systemic problem throughout the undergraduate biology degree and underscore the need for further examination and transformation of upper-division courses to support all students, even at late stages of their degrees.

Postsecondary biology students' ways of participating in the critique and discussion of primary scientific literature.

Science advances through the interplay of idea construction and idea critique. Our goal was to describe varied forms of productive disciplinary engagement that emerged during primary literature discussions. Such descriptions are necessary for biology educators and researchers to design for and recognize diverse repertoires of participation in the critique and discussion of primary scientific literature. We identified three cases (a lower-division ecology course, an upper-division organismal course, and a journal club embedded in a summer research program) that were each designed with weekly primary literature discussions. We analyzed 12 discussions (four from each case) to describe what postsecondary students attend to when they critique and what forms of participation emerged from students reading and discussing primary scientific literature. Students participated in critique in all three cases and patterns in the substance and framing of critiques reflected the level of the context (lower- or upper-division). Students also shaped how they participated in ways that were relevant to the science classroom communities in each case. Our findings suggest that structuring primary literature discussions in ways that both elevate and connect students' agency and personal relevance is important for fostering varied forms of productive disciplinary engagement within a science classroom community.

Integrating ArcGIS Online and digital story mapping for active learning in systematic geography courses

ABSTRACT Amid the shift to virtual teaching and learning during the COVID-19 pandemic, educators across disciplines were faced with developing new teaching strategies for active learning and significant learning experiences. This paper discusses findings from a case study of integrating ArcGIS Online and StoryMaps for assignments and semester projects in systematic geography courses – health, population, and urban geography. The study assesses the process of incorporating the use of this technology into these upper-division undergraduate courses, with a mix of both geography and non-geography majors, and student perspectives on their learning of and engagement with this technology. With broader applications to different course, discipline, and education contexts, findings suggest increased student engagement, enhanced understanding of course topics and their practical applications, and an appreciation for the opportunity to learn within and work with geospatial technology.

Increasing student interest with the Bacterial Unknown Identification Project: using mixed cultures to create real-world applications.

Many introductory-level classes teach fundamental concepts, as they are prerequisites for upper-division courses. Therefore, the student body in these classes has diverse interests. To address this breadth of career trajectory, introductory-level laboratory courses often include experiments that demonstrate a wide range of microbiological techniques and processes. One of the experiments that is a standard component of many microbiology classes, the Bacterial Unknown Identification Project (BUIP), is often limited to isolated organisms or a specific environment. Here, we describe an updated method for the BUIP that incorporates the projected student career diversity through the implementation of multiple mixed cultures of microorganisms associated with different environments. This update can be utilized in any microbiology laboratory classroom. We maintained the learning objectives, including applying appropriate microbiological methods to analyze and interpret results, and effectively communicate scientific findings, while modifying the sample composition. Assessment of the modification demonstrated that upon completion of the BUIP, students felt that the project applied to their career and it did not take too much of their free time to complete.

User experiences of college students using mental health applications to improve self-care: Implications for improving engagement

The purpose of this study is to evaluate themes on ‘user experiences’ among college students (N = 265) enrolled in an upper-division Psychopathology course who were assigned a project in which they were instructed to identify a self-care goal, choose from a list of six mental health-focused mobile applications (apps) provided by the instructor, and use the app over the course of three weeks to support progress towards their goal. Prior literature on user experiences typically evaluates user reviews, or asks participants to reflect on past app use or anticipate future use. Students reported their experiences using the app during key decision points: app selection, while using the app, and at the conclusion of the assignment. Using thematic analysis, results identified seven central themes and eight subthemes pertaining to the content of the app (e.g., app features) and the context of using the app (e.g., classroom assignment). Content-wise students liked: 1) features with a strong evidence base, namely, thought diaries and guided meditations; 2) progress tracking, because it increased awareness of mood/stressors, motivated students to see improvement, and helped them stay on track. Students appreciated having 3) crisis support resources; 4) app interfaces that allowed for customization (poor app interfaces were sometimes cited as the reason for disengagement); and 5) apps that included varied, comprehensive resources such that it felt like a one-stop shop. In addition to the content of features and design interface, the context in which mental health apps are introduced and used is important. The remaining themes related to the context in which the app was used, including 6) preparation for app usage, such as reviewing scholarly/credible sources, and 7) social support from fellow students completing the same assignment. Future research should evaluate the ‘who, what, when, why, where, and how’ of app utilization during key decision points, such as initial app selection or subscription renewal, to better understand the impact of user experience on engagement.
