BackgroundOpen Educational Resources (OERs) help instructors create innovative lessons and foster cost-effective and equitable access to educational materials. As more instructors turn to OERs to enhance their courses, there is a growing demand for the creation of more lesson plans. MethodsTo increase the number of high-quality OERs in undergraduate biology and physics, the journalCourseSourceintroduced Writing Studios to assist educators in writing and publishing OERs. Over a period of 5 years, 188 attendees participated in one of 11 different Writing Studios in which they followed a scaffolded worksheet to help draft their OER and engaged in peer review with partners. Attendees completed surveys before and after participation, and we tracked whether or not they published their manuscripts. ResultsWe found that 38.8% of attendees shared their OERs through aCourseSourcepublication. Several characteristics predicted OER sharing through publication such as format of the workshop and attendee’s type of institution. Participants also described a variety of supports and barriers that impacted their ability to publish as well as possible long-term supports that would help bring resources to publication. DiscussionThis study highlights the importance of ongoing support and tailored strategies to facilitate the sharing of OERs. The findings can benefit instructors and professional development leaders who are committed to increasing the number of high-quality resources that are available. 

ABSTRACT In undergraduate life sciences education, open educational resources (OERs) increase accessibility and retention for students, reduce costs, and save instructors time and effort. Despite increasing awareness and utilization of these resources, OERs are not centrally located, and many undergraduate instructors describe challenges in locating relevant materials for use in their classes. To address this challenge, we have designed a resource collection (referred to as Open Resources for Biology Education, ORBE) with 89 unique resources that are primarily relevant to undergraduate life sciences education. To identify the resources in ORBE, we asked undergraduate life sciences instructors to list what OERs they use in their teaching and curated their responses. Here, we summarize the contents of the ORBE and describe how educators can use this resource as a tool to identify suitable materials to use in their classroom context. By highlighting the breadth of unique resources openly available for undergraduate biology education, we intend for the ORBE to increase instructors’ awareness and use of OERs. 

With the onset of COVID-19, colleges and universities moved to emergency remote teaching, and instructors immediately adjusted their curricula. Many instructors adapted or developed new online lessons that they subsequently published as Open Educational Resources (OERs). While much has been examined related to how entire course designs evolved during this period, the same attention has not been paid to how individual lessons were structured to meet online learners’ needs. As such, we evaluated OER lessons for the integration of universal design for learning (UDL) guidelines and active learning strategies. We evaluated OER lessons published in CourseSource, which is an open-access, peer-reviewed journal that focuses on biology lessons implemented in undergraduate classrooms and provides the necessary details and supporting materials to replicate the lesson. We found that biology instructors used a variety of UDL guidelines and active learning strategies to encourage student learning and engagement in online teaching environments. This study also provides a collection of OER online lessons that instructors and educational developers can use to inform the practice of engaging biology students. 

Critical thinking is the process by which people make decisions about what to trust and what to do. Many undergraduate courses, such as those in biology and physics, include critical thinking as an important learning goal. Assessing critical thinking, however, is non-trivial, with mixed recommendations for how to assess critical thinking as part of instruction. Here we evaluate the efficacy of assessment questions to probe students’ critical thinking skills in the context of biology and physics. We use two research-based standardized critical thinking instruments known as the Biology Lab Inventory of Critical Thinking in Ecology (Eco-BLIC) and Physics Lab Inventory of Critical Thinking (PLIC). These instruments provide experimental scenarios and pose questions asking students to evaluate what to trust and what to do regarding the quality of experimental designs and data. Using more than 3000 student responses from over 20 institutions, we sought to understand what features of the assessment questions elicit student critical thinking. Specifically, we investigated (a) how students critically evaluate aspects of research studies in biology and physics when they are individually evaluating one study at a time versus comparing and contrasting two and (b) whether individual evaluation questions are needed to encourage students to engage in critical thinking when comparing and contrasting. We found that students are more critical when making comparisons between two studies than when evaluating each study individually. Also, compare-and-contrast questions are sufficient for eliciting critical thinking, with students providing similar answers regardless of if the individual evaluation questions are included. This research offers new insight on the types of assessment questions that elicit critical thinking at the introductory undergraduate level; specifically, we recommend instructors incorporate more compare-and-contrast questions related to experimental design in their courses and assessments. 

ABSTRACT Undergraduate genetics courses have historically focused on simple genetic models, rather than taking a more multifactorial approach where students explore how traits are influenced by a combination of genes, the environment, and gene-by-environment interactions. While a focus on simple genetic models can provide straightforward examples to promote student learning, they do not match the current scientific understanding and can result in deterministic thinking among students. In addition, undergraduates are often interested in complex human traits that are influenced by the environment, and national curriculum standards include learning objectives that focus on multifactorial concepts. This research aims to discover to what extent multifactorial genetics is currently being assessed in undergraduate genetics courses. To address this, we analyzed over 1,000 assessment questions from a commonly used undergraduate genetics textbook; published concept assessments; and open-source, peer-reviewed curriculum materials. Our findings show that current genetics assessment questions overwhelmingly emphasize the impact of genes on phenotypes and that the effect of the environment is rarely addressed. These results indicate a need for the inclusion of more multifactorial genetics concepts, and we suggest ways to introduce them into undergraduate courses. 

Open Educational Resources (OER) are widely used instructional materials that are freely available and promote equitable access. OER research at the undergraduate level largely focuses on measuring student experiences with using the low cost resources, and instructor awareness of resources and perceived barriers to use. Little is known about how instructors work with materials based on their unique teaching context. To explore how instructors engage with OER, we surveyed users of CourseSource , an open-access, peer-reviewed journal that publishes lessons primarily for undergraduate biology courses. We asked questions aligned with the OER life cycle, which is a framework that includes the phases: Search , Evaluation , Adaptation , Use , and Share . The results show that OER users come from a variety of institution types and positions, generally have positions that focus more on teaching than research, and use scientific teaching practices. To determine how instructors engage throughout the OER life cycle, we examined the frequency of survey responses. Notable trends include that instructors search and evaluate OER based on alignment to course needs, quality of the materials, and ease of implementation. In addition, instructors frequently modify the published materials for their classroom context and use them in a variety of course environments. The results of this work can help developers design current and future OER repositories to better coincide with undergraduate instructor needs and aid content producers in creating materials that encourage implementation by their colleagues. 

Abstract Field courses provide transformative learning experiences that support success and improve persistence for science, technology, engineering, and mathematics majors. But field courses have not increased proportionally with the number of students in the natural sciences. We conducted a scoping review to investigate the factors influencing undergraduate participation in and the outcomes from field courses in the United States. Our search yielded 61 articles, from which we classified the knowledge, affect, behavior, and skill-based outcomes resulting from field course participation. We found consistent reporting on course design but little reporting on demographics, which limits our understanding of who takes field courses. Cost was the most commonly reported barrier to student participation, and knowledge gains were the most commonly reported outcome. This scoping review underscores the need for more rigorous and evidence-based investigations of student outcomes in field courses. Understanding how field courses support or hinder student engagement is necessary to make them more accessible to all students.
