    开放科学运动产生了大量与期刊文章相关的公开发表的数据,为教育工作者创造了一个巨大的资源,让学生参与当前的主题和分析。然而,教育工作者面临挑战,使用这些材料,以满足课程目标。我提供了一个案例研究,使用开放科学(已发表的文章和相应的数据集)和开放的教育实践在一个顶点课程。在参与当前的保护主题时,学生在研究过程中追踪联系,学习统计分析,并使用编程语言R重新创建分析。我评估了开放文章和数据集中最佳实践的存在,在开放评分政策中检查学生的选择,对学生的学习收获进行了调查,并对学生的反思进行了主题分析。首先,文章和数据集满足了刚刚超过一半的评估公平实践,随着出版日期的增加。学生对评估类别的加权方式存在微小差异,反思突出了对学生代理的赞赏。在课程内容中,学生在描述变量时报告了最大的学习收获,而协作活动(例如,与同龄人和教练互动)是最有效的支持。促进这些学习成果的最有效任务包括编码练习和团队主导的任务。学生反思的自动编码确定了16个主题,积极的情绪比消极的情绪高出近4倍。学生在统计分析中积极反映了他们的成长,负面情绪集中在有限的统计和编码经验使他们感到紧张。作为一个群体,我们在使用开放科学材料方面遇到了一些挑战和机遇。我提出主要建议,根据学生的经验,供科学家在发布开放数据时考虑,为开放科学界提供额外的教育益处。
    The open science movement produces vast quantities of openly published data connected to journal articles, creating an enormous resource for educators to engage students in current topics and analyses. However, educators face challenges using these materials to meet course objectives. I present a case study using open science (published articles and corresponding datasets) and open educational practices in a capstone course. While engaging in current topics of conservation, students trace connections in the research process, learn statistical analyses, and recreate analyses using the programming language R. I assessed the presence of best practices in open articles and datasets, examined student selection in the open grading policy, surveyed students on their perceived learning gains, and conducted a thematic analysis on student reflections. First, articles and datasets met just over half of the assessed fairness practices, which increased with the publication date. There was a marginal difference in how assessment categories were weighted by students, with reflections highlighting appreciation for student agency. In course content, students reported the greatest learning gains in describing variables, while collaborative activities (e.g., interacting with peers and instructor) were the most effective support. The most effective tasks to facilitate these learning gains included coding exercises and team-led assignments. Autocoding of student reflections identified 16 themes, and positive sentiments were written nearly 4x more often than negative sentiments. Students positively reflected on their growth in statistical analyses, and negative sentiments focused on how limited prior experience with statistics and coding made them feel nervous. As a group, we encountered several challenges and opportunities in using open science materials. I present key recommendations, based on student experiences, for scientists to consider when publishing open data to provide additional educational benefits to the open science community.

    妇女和少数民族在合成生物学界的代表性不足。通过写作和交流参与科学界发展学术身份是STEM保留的重要组成部分,特别是对于代表性不足的个人。已经开发了几种优秀的教学工具来教授科学素养,并衡量阅读和解释科学文献的能力。然而,在写作方面衡量学习增益的工具较少,或者教授更抽象的同行评审和科学出版过程,这对于发展学术认同和出版货币至关重要。在这里,我们描述了我们在合成生物学课程中向本科生教授科学写作和出版的方法。在基于项目的学习中使用黄金标准实践,我们创建了一个写作项目,让学生成为合成生物学特定应用领域的专家,与重要的全球问题或挑战相关。为了衡量与我们的学习成果相关的学习收获,我们适应并扩展了学生的态度,能力,和信念(SAAB)概念清单,以包括有关科学写作过程的其他问题,作者身份,和同行评审。我们的结果表明,基于项目的方法在实现写作和同行评审出版物的学习目标方面是有效的。并导致较高的学生满意度和学生自我报告的学习收获。我们建议这些教育实践可以直接促进本科生作为合成生物学家的科学认同的发展,并将有助于创建更多样化的合成生物学研究企业。
    Women and racial minorities are underrepresented in the synthetic biology community. Developing a scholarly identity by engaging in a scientific community through writing and communication is an important component for STEM retention, particularly for underrepresented individuals. Several excellent pedagogical tools have been developed to teach scientific literacy and to measure competency in reading and interpreting scientific literature. However, fewer tools exist to measure learning gains with respect to writing, or that teach the more abstract processes of peer review and scientific publishing, which are essential for developing scholarly identity and publication currency. Here we describe our approach to teaching scientific writing and publishing to undergraduate students within a synthetic biology course. Using gold standard practices in project-based learning, we created a writing project in which students became experts in a specific application area of synthetic biology with relevance to an important global problem or challenge. To measure learning gains associated with our learning outcomes, we adapted and expanded the Student Attitudes, Abilities, and Beliefs (SAAB) concept inventory to include additional questions about the process of scientific writing, authorship, and peer review. Our results suggest the project-based approach was effective in achieving the learning objectives with respect to writing and peer reviewed publication, and resulted in high student satisfaction and student self-reported learning gains. We propose that these educational practices could contribute directly to the development of scientific identity of undergraduate students as synthetic biologists, and will be useful in creating a more diverse synthetic biology research enterprise.

    阅读,介绍,讨论同行评审的科学报告,案例研究,和评论对现代生物学教育至关重要。这些练习为学生未来专业活动的关键方面建模,并向学生介绍当前的科学概念和方法,数据分析,和介绍。与主要文献合作的一种常见形式是期刊俱乐部:在同龄人面前展示和讨论研究文献,它有许多优点。然而,在大型现代教室里,这种格式非常耗时和压力,特别是因为演讲不是一种普遍教授的技能。我们认为,由于历史上缺乏代表性或健康问题,当前的教育和专业范式对其构成挑战的学生群体被剥夺了关键的教育机会。为了解决这个问题,我们制定了一种称为同行评审演示交流(PRPE)的方法,专注于协作分析,介绍,并审查研究文献,包括(I)学生语音叙述的研究报告,(ii)由教师生成的检查表,以建立对提供信息的介绍或审查的期望,和(iii)陈述分配和同行评审过程。我们在3年的本科细胞生物学课程中测试了这种方法。评估前和评估后不仅展示了展示的学生,而且评审了展示的学生在自我效能感和知识方面都取得了显着进步;因此,同行评审的演讲是一种有效的学习工具。退出调查显示,大多数学生认为这种方法是有益的。我们的方法允许每个学生在低压力的创意环境中发言和提问。这是一个很好的可定制,可跟踪,和可扩展的低风险评估工具。
    Reading, presenting, and discussing peer-reviewed scientific reports, case studies, and reviews are essential to modern biology education. These exercises model crucial aspects of students\' future professional activities and introduce the students to the current scientific concepts and methodology, data analysis, and presentation. A common format for working with primary literature is a journal club: presenting and discussing research literature in front of peers, which has many merits. However, in large modern classrooms, this format is very time-consuming and stressful, especially since presenting is not a commonly taught skill. We argue that student groups for whom the current educational and professional paradigms present a challenge due to a historical lack of representation or wellness issues are deprived of a key educational opportunity. To solve this problem, we formulated an approach called Peer-Reviewed Presentation Exchange (PRPE), which focuses on collaborative analysis, presentation, and review of research literature that includes (i) voice-narrated research presentations by students, (ii) checklists generated by the instructor to establish expectations for an informative presentation or review, and (iii) presentation assignment and peer review process. We tested this approach in an undergraduate cell biology class over 3 years. Pre- and post-assessments show significant gains in self-efficacy and knowledge not only by students who presented but also by the students who reviewed the presentations; therefore, peer-reviewed presentations are an effective tool for learning. Exit surveys show that the approach is seen as beneficial by most students. Our approach allows every student to speak and ask questions in a low-stress creative environment. It is an excellent customizable, trackable, and scalable low-stakes assessment tool.

    有效的科学交流已被确定为神经科学教育的核心能力之一,正如2017年FUN研讨会所阐述的那样。然而,大多数本科生并没有收到关于如何有效地将科学传播给多元化受众的明确指导。相反,交流作业通常帮助学生熟练通过研究文章与其他科学家分享科学信息,海报介绍或口头介绍。这提供了一个错失的机会,指导学生与公众沟通的复杂性,在COVID-19大流行期间,其重要性已成为人们关注的焦点。翻译研究结果,以便非专业受众理解它们需要实践和深度学习,并且可以作为一个强大的教学工具来帮助学生培养科学素养技能。在这里,我分享了旨在解决神经科学教育核心能力的广泛科学交流任务的蓝图。这项任务是一所小型公立文科大学400级神经药理学课程的最终项目。学生小组工作,以确定感兴趣和研究的主题,脚本,录制面向普通观众的音频播客。作业是脚手架,以允许学生小步完成最终提交工作,并从教师和他们的同伴那里获得反馈。这些反馈步骤与修改工作的机会配对,以进一步发展学生的沟通技巧。学生的初步反馈表明,这项作业促进了更深入的学习和对课程内容的更高参与度。
    Effective science communication has been identified as one of the core competencies of neuroscience education as articulated at the 2017 FUN Workshop. Yet most undergraduate students do not receive explicit instruction on how to effectively communicate science to a diversity of audiences. Instead, communication assignments typically help students become proficient at sharing scientific information with other scientists through research articles, poster presentations or oral presentations. This presents a missed opportunity to instruct students on the complexities of communicating to the general public, the importance of which has come into sharp focus during the COVID-19 pandemic. Translating research findings so they can be understood by a non-specialist audience requires practice and deep learning and can act as a powerful teaching tool to help students build science literacy skills. Here I share the blueprint to a broadly-oriented science communication assignment built to address the core competencies of neuroscience education. The assignment acts as the final project for a 400-level neuropharmacology course at a small public liberal arts university. Students work in small groups to identify a topic of interest and research, script, and record an audio podcast geared towards a general audience. The assignment is scaffolded to allow students to work towards the final submission in small steps and to receive feedback from the instructor and their peers. These feedback steps pair with opportunities to revise their work to further develop students\' communication skills. Initial feedback from students suggests the assignment promoted deeper learning and higher engagement with course content.

    学习阅读科学文献是本科科学教育的重要组成部分。本科理科学生学习分析数据,阅读主要文献,并将文章中的知识整合为对研究领域的凝聚力理解。通常,一堂课包括阅读初级文学的不同经验的学生,这使得很难制定足够平易近人但对每个学生都具有挑战性的作业。在这里,我描述了旨在解决这一问题的中级神经生物学课程的三部分作业。每个学生首先被分配了一篇阿片类药物研究领域的文章,他们在数字时间表的条目中总结了这一点。第二,学生们向全班展示了他们的时间表条目,编制的数字时间表在网上公开。在作业的第三部分,学生们写了一篇简短的观点论文。这里,学生解释了他们分配的文章如何适合使用他们的同学\'时间表条目的研究领域,以及在时间线之外包含其他引用的选项。这个由三部分组成的作业旨在为各级学生提供一个支持性但具有挑战性的项目。该项目被设计为非一次性任务,与其他学习目标和教学实践保持一致,包括跨学科意识,写作学习,包容性教育学。此分配的版本已用于亲自和远程指令。
    Learning to read scientific literature is a crucial component of an undergraduate science education. Undergraduate science students learn to analyze data, read primary literature, and integrate knowledge across articles into a cohesive understanding of a field of study. Often, a class includes students with varying experience reading primary literature, making it difficult to develop assignments that are adequately approachable yet challenging for every student. Here I describe a three-part assignment for an intermediate level neurobiology course that seeks to address this concern. Each student was first assigned a single article in the field of opioid research, which they summarized in an entry for a digital timeline. Second, students presented their timeline entries to the class, and the compiled digital timeline was made publicly available online. In the third part of the assignment, students wrote a brief perspective paper. Here, students explained how their assigned article fit into the field of study using their classmates\' timeline entries, along with the option to include additional references outside of the timeline. This three-part assignment sought to provide a supportive yet challenging project for students at all levels. The project was designed as a non-disposable assignment, aligned with additional learning goals and pedagogical practices, including interdisciplinary awareness, writing-to-learn, and inclusive pedagogy. Versions of this assignment have been used for both in-person and remote instruction.

    神经科学是许多高等教育机构中新兴且密集的本科专业,神经科学教育的一些领域需要进一步发展。这种需要的发展之一是,除了传统的学科知识获取之外,更加注重采购与职业相关的技能。技能发展在神经科学教育中尤其具有挑战性,因为该学科的跨学科性质为毕业生提供了非典型的广泛潜在职业。许多神经科学职业的共同技能包括理解和分析定量数据并根据这些分析得出结论的能力。这里介绍了一种主动学习的教学方法,涉及分析主要科学文献中的开创性文章,以提供分析数据并从这些数据中得出结论的实践,同时学习突触传递的基本原则。选择了突出原理的文章,例如Ca2在突触释放中的作用,胞吐作用,定量释放,和突触延迟。从这些文章中选择了可以很容易地用于教导这些原理的数字,并提出了有助于指导学生分析数据的问题。需要更多这样的活动来促进帮助学生获得与神经科学生产性职业相关的技能的过程。
    Neuroscience is a burgeoning and intensive undergraduate major at many institutions of higher education and several areas in neuroscience education need further development. One such needed development is an increased focus on the procurement of career-relevant skills in addition to the traditional acquisition of subject knowledge. Skill development is particularly challenging in neuroscience education as the subject\'s interdisciplinary nature provides an atypically broad range of potential careers for graduates. Skills common to many careers in neuroscience include the ability to understand and analyze quantitative data and to draw conclusions based on those analyses. Here is presented an active learning pedagogical approach involving the analysis of seminal articles in the primary scientific literature to provide practice in analyzing data and drawing conclusions from those data while at the same time learning the fundamental tenets of synaptic transmission. Articles were selected that highlight principles such as the role of Ca2+ in synaptic release, exocytosis, quantal release, and synaptic delay. Figures from these articles that can readily be used to teach these principles were selected, and questions that can help to guide students\' analysis of the data are also suggested. Activities like this are needed in greater numbers to facilitate the process of helping students gain skills relevant to a productive career in neuroscience.

    本案例研究旨在帮助学生探索剪接体的分子机制以及SARS-CoV-2如何影响宿主细胞剪接体功能,同时解释主要文献中的数字(A.K.Banjeree,etal.,单元183:1325-1339,e1-e10,2020年,https://doi.org/10.1016/j。cell.2020.10.004)。“皮特和失踪的剪刀”是在2022年春季和2022年秋季在两个大型招生(150+)分子生物学入门课程中设计和实施的,公共研究机构。案例研究的格式与国家科学案例研究教学中心(NCCSTS)框架保持一致,这已经被证明是有效的,以学生为中心的方法在本科阶段教授复杂的生物学概念。该案例研究有四个学生学习目标(SLO),与Bloom的修订分类法保持一致,并要求学生对剪接的分子机制有一个理解,并分析和解释主要文献中的一个数字。本活动包括形成性和总结性评估问题,每个问题映射到一个案例研究SLO。总结性评估问题以前/后的方式给出,配对t检验用于评估学生评估前后分数之间的差异。评估结果表明,两个课程的学生都掌握了本案例研究的每个SLO,鉴于与评估前相比,评估后分数显着增加。这些发现表明,“皮特和缺失的剪刀”案例研究是培养学生对剪接体理解的有效方法,以及从主要文献中解读数字的能力。
    This case study was designed to help students explore the molecular mechanisms of the spliceosome and how SARS-CoV-2 impacts host cell spliceosomal function while interpreting figures from primary literature (A. K. Banjeree, et al., Cell 183:1325-1339, e1-e10, 2020, https://doi.org/10.1016/j.cell.2020.10.004). \"Pete and the Missing Scissors\" was designed and implemented in the spring of 2022 and fall of 2022 in two large-enrollment (150+) introductory molecular biology courses at a large, public research institution. The case study was formatted in alignment with the National Center for Case Study Teaching in Science (NCCSTS) framework, which has been shown to be an effective, student-centered approach to teaching complex biological concepts at the undergraduate level. The case study had four student learning objectives (SLOs) that aligned with Bloom\'s Revised Taxonomy and required students to develop an understanding of the molecular mechanisms of splicing and analyze and interpret a figure from primary literature. Both formative and summative assessment questions are included in this activity, with each question mapping to one of the case study SLOs. Summative assessment questions were given in a pre-/post-manner, and a paired t-test was used to evaluate differences between students\' pre- and post-assessment scores. Assessment results demonstrated that students in both courses mastered each of the SLOs of this case study, given the significant increase in post-assessment scores compared to the pre-assessment. These findings indicate that the \"Pete and the Missing Scissors\" case study is an effective approach to develop students\' understanding of the spliceosome, as well as ability to interpret figures from primary literature.

    目的:对主要文献的批判性评估和理解对药学实践至关重要。该项目在重症监护选修课程中评估了学生的信心和学习成果,其中播客被用作文献评估的主动学习任务。
    方法:药学三年级学生创建了一个15到20分钟的播客,回顾了一个具有里程碑意义的重症监护试验。使用前/后调查来评估学生对评估主要文献的信心的看法。使用标准化的规则来评估多个领域的文献评估技能。
    结果:92名药学三年级学生参加了重症监护选修课程,93%(92人中有86人)完成了调查。学生对他们评估文学的能力的看法在所有七个问题中都得到了改善,包括在解释研究方法和将文献发现应用于患者护理方面的舒适度。学生对标准化规则的大多数组成部分进行了精通,讨论结果和结论的能力是表现最差的领域(78.2%完全熟练)。完成活动后,学生对解释结果更有信心,应用发现,并向同行口头发表期刊文章。大多数学生认为播客活动帮助他们加强了文学评估技能,并向同龄人推荐了这项活动。
    结论:第三年药学专业学生报告说,在创建播客事件回顾重症监护试验后,对主要文献的解释和应用的信心有所改善。将来应该研究创建播客或其他音频/视觉方法的其他研究。
    OBJECTIVE: Critical evaluation and understanding of primary literature is essential to pharmacy practice. This project evaluated student confidence and learning outcomes in a critical care elective course where podcasts were used as an active learning assignment for literature evaluation.
    METHODS: Third-year pharmacy students created a 15- to 20-min podcast episode that reviewed a landmark critical care trial. A pre/post survey was used to assess student perceptions of confidence in evaluating primary literature. A standardized rubric was used to assess literature evaluation skills in several domains.
    RESULTS: Ninety-two third-year pharmacy students were enrolled in the critical care elective course, and 93% (86 of 92) completed the survey. Student perceptions of their ability to evaluate literature improved for all seven questions, including comfort in interpreting study methodology and applying findings of literature to patient care. Students scored proficient on most components of the standardized rubric, with ability to discuss results and conclusions being the lowest performing domain (78.2% fully proficient). After completing the activity, students felt more confident in interpreting results, applying findings, and orally presenting a journal article to peers. Most students felt the podcast activity helped them strengthen their literature evaluation skills and recommended this activity to a peer.
    CONCLUSIONS: Third-year pharmacy students reported an improvement in confidence in the interpretation and application of primary literature after creating a podcast episode reviewing a critical care trial. Additional research with creation of podcasts or other audio/visual methods should be studied in the future.

    科学有效传播是科学素养发展的重要组成部分。研究表明,通过期刊俱乐部引入初级科学文献可以改善学生的学习成果,包括增加科学知识。然而,没有脚手架,学生可能会错过更复杂的科学素养,包括如何分析和呈现科学数据。在这项研究中,我们应用一个修改的CREATE(S)过程(概念图介绍,阅读方法和结果,阐明假设,分析数据,想想下一个实验,和综合图)提高学生的科学素养技能,特别是他们对科学过程的理解以及他们使用叙事综合来传达科学的能力。我们在高年级本科课程中使用回顾性准实验研究设计测试了这一假设。我们将CREATES干预学生的学习结果与在引入CREATES之前参加过相同课程的学生的学习结果进行了比较。规则指导,直接证据评估用于衡量学生在学习成果方面的收获.分析显示,CREATES干预学生与对照组相比,表现出更好的解释和交流主要文献的能力,尤其是在方法上,假设,和叙事综合学习成果类别。通过对CREATES干预小组完成的反思作业的混合方法分析,学生报告说,合成图是过程中最常用的步骤,对他们的学习非常有价值。一起来看,这项研究展示了这种修改后的CREATES过程如何促进科学素养的发展,以及它如何在科学中应用,技术,工程,和数学杂志俱乐部。
    Communicating science effectively is an essential part of the development of science literacy. Research has shown that introducing primary scientific literature through journal clubs can improve student learning outcomes, including increased scientific knowledge. However, without scaffolding, students can miss more complex aspects of science literacy, including how to analyze and present scientific data. In this study, we apply a modified CREATE(S) process (Concept map the introduction, Read methods and results, Elucidate hypotheses, Analyze data, Think of the next Experiment, and Synthesis map) to improve students\' science literacy skills, specifically their understanding of the process of science and their ability to use narrative synthesis to communicate science. We tested this hypothesis using a retrospective quasi-experimental study design in upper-division undergraduate courses. We compared learning outcomes for CREATES intervention students to those for students who took the same courses before CREATES was introduced. Rubric-guided, direct evidence assessments were used to measure student gains in learning outcomes. Analyses revealed that CREATES intervention students versus the comparison group demonstrated improved ability to interpret and communicate primary literature, especially in the methods, hypotheses, and narrative synthesis learning outcome categories. Through a mixed-methods analysis of a reflection assignment completed by the CREATES intervention group, students reported the synthesis map as the most frequently used step in the process and highly valuable to their learning. Taken together, the study demonstrates how this modified CREATES process can foster scientific literacy development and how it could be applied in science, technology, engineering, and math journal clubs.

    能够进行科学交流是获得科学学位的学生的一项重要技能。在未来的研究生院和科学专业的职业生涯中使用的技能包括口头和书面沟通,以及科学素养和能够创建数字来显示信息。人们一致认为,应该在整个本科科学课程中教授这些技能;然而,许多教师指出,没有足够的时间来涵盖技能和开发材料来有效地融入这些技能,特别是低层次的内容为重点的课程。这里,我们提出了一个积极的课程,可以很容易地纳入任何内容为重点的本科细胞生物学课程。该课程围绕科学文献设计,使学生参与多种主动学习活动,以培养不同类型的科学交流技能。该课程不仅培养了学生在科学交流中的技能和自我效能感,它还使他们参与课程内容,并激发他们对研究的兴趣。虽然对课程进行更改以包括科学交流可能很困难,做一些小的改变,例如将该课程添加到已经存在的以内容为重点的课程中,可能会对早期本科理科学生的技能和态度产生重大影响。
    Being able to communicate scientifically is an important skill for students graduating with a science degree. Skills used in future graduate school and careers for science majors include oral and written communication, as well as science literacy and being able to create figures to display information. There is a consensus that these skills should be taught throughout an undergraduate science curriculum; however, many instructors have cited insufficient time to cover skills and develop materials to effectively incorporate these skills, especially into lower-level content-focused courses. Here, we present an active curriculum that can easily be incorporated into any content-focused undergraduate Cell Biology course. The curriculum is designed around scientific literature that engages students in a multitude of active learning activities to develop different types of scientific communication skills. This curriculum not only develops student skills and self-efficacy in scientific communication, it also engages them in course content and stimulates their interest in research. While making changes to a course to include scientific communication can be difficult, making small changes, such as addition of this curriculum to an already-existing content-focused course, could make a big difference in the skills and attitudes of early undergraduate science students.
